As a system administrator I am responsible for the security and the weakest link is user behaviour...

I have the following problem. Assume the users login from untrusted loaned computers at conferences, hotels, Internet cafes etc.

If I let users log in over SSH with password authentication then basically anyone on the Internet can try to guess passwords, or someone could have watched as my colleague typed his password and then try from another host. Not very comforting.

An other possibility is to use client certificates. Looks good with a passphrase, but I have no way of knowing if the user has removed the passphrase from his certificate. If such an unprotected certificate is stolen (because my colleague forgot to remove it from the PC) it can be copied to everywhere and the cracker can login at will.

What I would like to do is to require a client certificate AND password authentication on the server side (two factors). But I don't see how to configure SSHD to require two concurrent authentication approaches unless something like SecurID is used.

client certificate isn't a factor. client certificate is some organization (possibly 3rd party) attesting to the validity of the binding between a public key and some other information (like name or email address, etc). It was originally invented as something of an analog to the letters of credit from the sailing ship days .... that relying parties had no direct way of verifying information ... so had to rely on some hard copy that the person carried with them and could pass around.

In the modern world with online environment and/or prior reliationship between the entity being authenticated and the relying party .... certificates are mostly redundant and superfluous.

3-factor authentication
• something you have (frequently hardware token)
• something you know (pin or password)
• something you are (biometrics)

2-factor authentication can be hardware token and a pin/password that is used to activate the hardware token. The hardware token can implement digital signature technology using public/private key pair where the key pair is generated on the token and the private key is never allowed to leave the token. The PIN is then used to activate the token aka just stealing the token isn't sufficient to compromise the system, and/or just using something like social engineering to obtain the PIN doesn't directly accomplish anything w/o also stealing the hardware token.

The issue with regard to non-hardware tokens (aka software envelopes) for private key containers is that vulnerabilities and threats assesements tend to gravitate to independent failure/exploit; the issue with software containers is that they may be easier to steal than pin/passwords ... and so there isn't true independent 2-factor authentication. The difference is especially true when the software container can be copied with no knowledge of the owner ... via-a-vis knowing that a hardware token is missing and will generate lost/stolen report.

There has to be some process that registers the public key ... so that digital signature authentication can be performed. In the case of a CA infrastructure with certificates ... they basically have an RA (or registgration authority) function that performs the public key registration ... and then generates a certificate that can be used to indicate/representation to others that a valid registration has been performed by somebody for some purpose.

However, it is possible for valid businesses to directly perform the public key registration and not be dependent on other parties to perform the function (along with the complexity of what does a certificate really mean). This registration of a public key can use the same business process that registers a password in a shared-secret paradigm.

What is important for 2-factor authentication is totally orthongonal to the existance of a redundant and superfluous certificate ... it is does the registration process actually validate that the public key being registered originates from an hardware token with acceptable integrity characteristics. It is totally independent of whether or not anybody actually bothered to generate a (redundant and superfluous) certificate in response to the registration process .... but did the registration process use the appropriate due diligence with regard to the public key being registered.

disclaimer ... there is now an instantiation of the aads chip strawman that i originally postulated several years ago:
https://www.garlic.com/~lynn/x959.html#aads

the comfort level for appropriate 2-factor authentication may be whether due diligence has been taken in validating that the public key being registered (whether it is in an SSH table, or a RADIUS account table, or a Kerberos table, or some other kind of table) actually originated with a hardware token of the appropriate integrity characteristic (regardless of what some certificate might say about the public key).

Søren Roug writes:
OK, I wasn't being completely clear here. When speaking about certificates I meant the kind of public key pair generated by ssh-keygen.

It takes the place of a hardware token in conventional two-factor authentification. Unlike real hardware tokens it can be copied/stolen without the user noticing, but it does add the level of security that only persons with access to copy the private keyfile will be able to try to log into the server over ssh.

And unlike real hardware tokens it costs nothing.

rather than 2-factor authentication ... then it is more of an issue of shared-secret authentication vis-a-vis non-shared-secret authentication.

the registration of the public key at the relying-party ... aka at the site accepting the SSH connection ... rather than a password ... implies that even given knowledge of the public key ... it is not possible to impersonate the entity ... while knowing a shared-secret allows impersonation.

hardware tokens tend to use non-shared-secret paradigms because they tend to offer more protection than shared-secret paradigms. note that there is some additional confusion with the terms password/pin. A password/pin that is registered at a remote site ... is a shared-secret ... a password/pin that is known only to an individual and their privately owned hardware token is not a shared-secret.

there are specific exploits/vulnerabilities with regard to shared-secret and non-shared-secret paradigms. these are somewhat independent of exploits/vulnerabilities with regard to 2/3-factor authentication. They overlap in the sense that a something you know factor can be implemented as either shared-secret ... registered with other parties ... or non-shared-secret (like in hardware tokens where it is not known to other parties).

When IBM designed S/360, the first "architecture", they were hoping for a long life, but I don't think anyone believed it would still be going after 40 years.

ibm was planning on doing something completely different in the early '70s called future system (FS) ... which eventually got canceled. However, there is some contention that Amdahl left to do his own 360/370 plug compatible because it seemed like IBM was going to walk away from the 360. In Amdahl's talk at MIT auditorium in the early '70s ... sort of giving his business case justification ... was that there was a $100b in software already written for the 360, and even if IBM totally walked away from 360, the legacy software (at that time) should provide him with viable market until the end of the century (nearly 30 years). random fs refs:

Han't lots of FS surfaced in the AS/400 etc., and some of it in the innards of AIX?

the lore is that some number of the people from the canceled FS project migrated to rochester and created the s/38. as/400 is follow-on to s/38.

FS was heavily object as part of the machine instruction level ... as well as one level store. I'm not sure how much of AIX could be considered FS. The as/400 maintained a fairly high-level abstraction and was able to port from a CISC hardware to power/pc RISC hardware with little impact to customers.

in addition to lore that Amdahl left to do 360 pcm, in part because it appeared that the company would be walking away from 360 with the FS strategy:
https://www.garlic.com/~lynn/submain.html#futuresys

there is also some lore that 801/risc in the early to mid 70s was a re-action to FS ... to go as far as possible to the opposite extreme by putting as little as possible in the hardware (as opposed to putting as much as possible in the hardware). Higher level abstraction could be be provided by software thru the CPr operating system and the PL.8 programming language ... running on top of minimalist hardware.
https://www.garlic.com/~lynn/subtopic.html#801

then in some sense, as/400 running on power/pc is a convergence of the FS extremes with high level abstraction ... and risc with minimalist hardware.

That sounds wrong.

I know a 4381 is no speed daemon in processor speed, but I remember doing compiles on one in college, and big COBOL programs took seconds most of the time. The longest I ever saw was for some job which took about 3 minutes, but we had 10 users locally, and I don't know how many from other schools.

The 4381 was in Richmond, VA, and was shared by several community colleges.

there were some really big/slow ada compilers. somewhat aside, i remember may eldest sending me email 20+ years ago from a college student machine and commenting during the day that trivial response to edit input was on the order of minutes (bsd running on a vax).

4381 was faster follow-on to 4341. 4361 was follow-on to 4331 ... much slower processor. however, all four were as fast or much faster than 360/67 on which we use to have sub-second trivial response with 75-80 users. some of the change is software bloat (even tho many of these online university 43xx machines were running vm/370, a derivative of cp/67) and some was that they tended to be configured with less disk thruput capcity (aka the argument that relative disk system thruput declined by a factor of ten times between the late 60s and the early 80s, disk thruput improvement was much less than cpu & memory thruput).

I was not present at the creation of the Amdahl corp or machines, but my understanding is that Amdahl wanted to build a non-360, Cray killer inside IBM, but IBM said it had to be a 360. Amdahl left, decided that there were 100 billion little green reasons to build a 360 and did so. This is not really contradictory to your story, but is a little bit different.

Once, pundits predicted that the mainframe computer was a dinosaur heading for extinction. These huge classics of the corporate computing world were reaching the end of the line and would give way to the new generation of server-based systems.

But IT workers with mainframe experience are getting older. A study by the Meta Group last year found that 55 per cent were over 50, compared with fewer than 10 per cent of those with Unix or Windows NT server skills.

So, the real question is: What point are you trying to make, or what is your real question? Code written in 1970 will run on a zSeries machine today. There are many applications running that were coded 10 or 20 (or more) years ago. There are many of those older programs that will also run on a PC under the Hercules emulator, running MVS 3.8. There are still quite a few large corporations that use mainframe systems, and still a number of companies writing/maintaining applications for those corporations (CA, BMC, Compuware, and others). There are a lot of folks who spent their entire careers writing code for S/360, S/370, S/370XA, S/390 and/or zArch systems, and there are still people working (like myself) who continue to write code for them.

and as i'm found of pointing out ... most of the 360s and the low-end and mid-range 370s were all "micro-coded" machines ... aka the implementations were not all that different from the current crop of "mainframe" emulators (like hercules) running on intel platforms.

late 70s/early 80s there was a project to switch the large number of different micro-code engines to 801/risc ... including the low-end and mid-range 370 (aka like for the follow-on to the 4341) .. which eventually got killed (although there are a number of 801/risc chips as support processors in various places today). there has been a related mainframe thread playing out in comp.arch & a.f.c.:

https://www.garlic.com/~lynn/subtopic.html#545tech

when ed (at csc) did internal network support, vnet/rscs, the support was added to propagate the instant message command thru the network ... so instead of
msg userid abcd....

it became
msg vnet msg nodeid userid abcd.....

i would claim that the internet is common infrastructure, somewhat akin to the highway system (and some of the past information superhighway analogies). huge numbers of people contribute to the financing of the common infrastructure ... and it is possible for individuals to abuse their share of the infrastructure ... akin to 18-wheelers abusing the highway network.

In part, this is because that actual use is hardly metered, and therefor it is possible to design strategies (like spam) where actual use is one hundred times or more larger than the direct financial contribution to their share of the internet (aka fully loaded cost of huge spamming is more than 100 times larger than the price charged the spammers). One might make the analogy to people growing rice in a desert ecology because the price they pay for water is less than one cent on the dollar of the cost of providing the water.

Somebody claiming to have spewed out over 200 million spams per day (120 million spams per 12 hrs) is analogous (but multiplied by factor of 100 or more) to "overloaded" trucks on the nations highways ... threatening the infrastructure integrity because of the excessive payloads.

so doing a similar analysis to that of fuel tax & road costs:
https://www.garlic.com/~lynn/2002j.html#41 Transportation
https://www.garlic.com/~lynn/2002j.html#42 Transportation

aka ... effectively the cost of building and maintaining roads is based on use/loading by heavy trucks. a majority of that cost is underwritten by fuel tax against everybody. However, if the costs were really born by the entities responsible for the cost ... then the fuel tax would be removed from all but heavy trucking ... and the tax for heavy trucking possibly increased to $20/gal (in order to accurately reflect direct cause and effect between the reasons for the costs and the payment of the costs).

Now, things that are heavily transportation related, like food distribution, could see significant price increases. However, again, this is akin to zero sum budgeting ... everything that directly incurs costs are directly charged proportional to the cost incurred. aka ... the current amortizing of road costs across all vehicles heavily subsidizes heavy trucking as well as products heavily dependent on heavy trucking.

so doing similar analysis with regard to spamming. Lets say the current infrastructure has 60 million accounts paying $20/month plus another $5/month amortized consumer computer related purchases .. for a total of $25/month or maybe $1.5b/month.

Hypothetically, lets say that spammers are consumming on the order of 25 percent of that infrastructure ... or roughtly equivalent to $375m/month ... mostly attributable to the top ten spammers. Using direct prorated charging ... those ten spammers should be each charged $37.5m/month (along with a corresponding reduction in the end-user monthly cost).

For argument sake, lets say that the spammers are actually being charged on the order of $5k/month (or less) rather than $37.5m/month and possibly are earning maybe $50k/month. In effect, to clear possibly $40k/nmonth or less, they are taking advantage of other peoples' resources to the tune of nearly $40m/month .... aka they are in effect burning $1000 of other people's money for every dollar they are realizing. This is an horrendously, enormous inefficiency ... and has no plausable economic benefit to the overall industry.

In effect, they are doing it because they can.

In the heavy trucking industry ... they may only be subsidized to the tune of 10:1 .... aka other entities are paying $20 (to build roads that are heavy truck capable) for every $1 earned in the trucking industry. Now even with such heavy subsidy, there are still instances where entities try and take further advantage of the infrastructure, like heavily overloaded trucks that create real threats to the integrity of the infrastructure. This gives rise to at least the weigh stations to try and curb the worst abuse.

The issue in the ISP industry is that the cost of the weigh-station equivalent probably can't be born by the spamming industry. While they may be creating the economic burden on the infrastructure to the tune of $375m/month ... they possibly are only bringing in $500k/month (this is the horrible, nearly 1000 to one, mismatch between the burden that they are placing on the infrastructure vis-a-vis the limited economic benefit realized from such activities).

In the heavy trucking world ... a subsidy of ten-to-one is possibly deamed tolerable because it achieves indirect subsidies of other (possibly desirable) objectives (that happen to be transportion related), like cheap(er) food. However, it is hard to understand a subsidy infrastructure of something like thousand-to-one with no observable general benefit.

i recently ran across an old reference from the late '70s wondering whether there were more tankers than there were 370/168s. This was someone supposedly looking at data processing systems on tankers in conjunction with using them to improve collision avoidance ... the claim was that something like 10 percent of the inventory was lost each year to collisions ... oh, and supposedly there were something like five times as many tankers world wide as there were 370/168s.

I was thinking about building a new rail system where one didn't exist. Have you driven along these highways through any commercial center? There isn't much expansion room except up. And around here, bridges seem to be so expensive that even maintenance is beyond our public pocketbooks (but that's yet another political issue).

Forget about underground; the northeast is at the end of a boondoggle called the Big Dig.

then there are all the public lobbying groups. when they widen 101 from four lanes to six (and sometimes eight) and put in the new section south of el camino (south san jose, about where the ibm, oops, hitachi plant site is), publlc lobbying insisted that the ten mile coyote valley section from about bernal to cochran be only four lanes.

this created huge traffic jams in the morning going north at cochran where it narrowed from six to four lanes and in the evening going south at bernal where it narrowed. for several years this added something like 15 minutes to the morning and evening compute for possibly tens of thousands of people ... say 30minutes/day, 20k people, 10khours/day @ $10/hr, something like $100k/day people costs, $2.3m/month, $28m/year (much higher if use $100/hr). There was some suggestion that the state send a bill for the additional people costs to the public lobbying group each month.

last week there was big celibration that the coyote valley section was retrofitted with the two additional lanes at enormous additional cost (compared to it having been built at six lanes to begin with).

san jose's light rail is another issue. the original specs called for break-even use volumes based on elapsed commute times being dependent on light rail having off-grade crossings .... aka light rail didn't have to share intersections with automobiles. however, somewhere along the way, there was a decision to save on construction costs by not implementing off-grade crossings at numerous places. This resulted in significant increase in transit time (people in south valley commuting to computer businesses like intel, amd, etc) ... making it much less attractive as a commuting method (which adds more cars to the intersections, slowing things down even more).

Why do they need to track? From what I understand the pre-paid cards do, the tracking is a real time usage subtracted from a number. That is accessed at the beginning of a call to tell the customer the remaining minutes and then the number is decremented (I presume) each minute of on-line use.

Why isn't that done with regular accounts? These long distance plans are so f**king complicated, the companies have to keep track of a gazillion variables added five different ways.

but that is real time ... not long term ... there is no necessity in keeping line-item billing that you might have with stuff like long distance. and of course, if you have line-item billing ... then you also need to have enough operators in the customer call center to handle people who want to dispute specific line-items. all goes away with pre-paid.

It's pretty common to do the key generation in the factory when the card is first personalized, but it can also be done by the user.

a number of cards have key generated at personalization (after the chip is in the 7816 carrier and embedded in plastic). This is frequently because the chip lacks the "power" to perform adequate random number generation as part of generating the key pair. In these situations, the key is generated in an external source and injected into the card.

One could postulate that a number of these cards/chips also implement RSA digital signatures as opposed to DSA or ECDSA for the same reason, RSA infrastructure use of random numbers can be defined as noches as part of messages from an external source. DSA/ECDSA require random number as part of the actual signing process (as well as part of key generation).

the aads chip strawman specified a ECDSA key-pair that was generated in the chip:
https://www.garlic.com/~lynn/x959.html#aads

and the private key never leaves the chip and is never divulged. The implication is that the key generation and the signing process requires a fairly robust random number generation implementation in the chip.

This is part of a certificate-less, non-PKI public key infrastructure.

where the key-pair is generated during power-on/test in the chip fab (before the wafer is even sliced & diced). The objective is to bind the integrity characteristics of the chip to the public key ... aka
can you say with any degree of certainty the real integrity characteristics of any chip inside a 7616 carrier embedded in a piece of plastic?

... I may have no idea who has the card ... but given that a specific public key authenticates a digital signature produced by the card ... some assumption can be made about the integrity level of the environment that produced that digital signature.

3278 was sort of the 3277 replacement. original 3272 controller had lots of the electronics in the 3277 keyboard and head. for the 3278, a lot of the electronics were moved out of the individual (3278) terminals and into the shared 3274 controller (making each terminal somewhat less expensive to manufactur).

one of the characteristics of knowledge work is that it is relatively distance insensitive ... not a lot of transportation expenses &/or delays.

MVS (or rather JES) flushes the job if there is anything wrong with the input or output dataset allocations, to avoid wasting thruput: no way anyone is going to waste time changing or fixing anything without editing the deck, or changing the actual names and allocations, and resubmitting. There is some amount of error recovery if things go not too badly wrong during job execution, but that is very dependent on the hardware configuration, and relies on there being another path available on which to redrive the I/O.

and the jes-based nje networking flushes network stuff if the origination and destination nodes both weren't in the local table. this started out having nodes defined in what was left over in the 255-entry psuedo device table (nominally maybe 160-200 entries available). this is one of the reasons that a real mvs/nje node could be trusted as an intermediate node on the internal network.

somewhat after the time the internal network exceeded 1000 nodes, the mvs jes limitation was raised to 999 nodes. the 20th aniv. of the 1000th node on the internal network is coming up. 10jun2003 ref:

the other reason that real mvs jes nje could be trusted as an intermediate node (or even barely any kind of node) was that nje header jumbled bunch of networking and non-networking together ... which led to imcompatibilities between different releases of mvs jes ... and system crashes.

the base internal networking that started it all was vnet/rscs which had its own native drivers ... but because of the way it layered things, it could also run multiple different kinds of nje drivers. this was leveraged to have lots of jes nje release specific drivers that did canonical nje header rewrites ... aka ... when vnet had a direct connection to a real mvs jes system ... the appropriate nje driver in vnet was started to try and minimize mvs crashes due to incompatible headers.

by the time bitnet started ... it appeared that the only drivers shipping to vnet customers where standard nje drivers. this possibly minimizedq the negative comparison of native nje compared to native vnet ... and of course it couldn't work the other way around ... jes ever running vnet drivers ... this was a really novel concept to vnet from the beginning ... and didn't even show up in arpanet until 1/1/83 cut-over to ip protocol. misc. bitnet/earn

the multi-user, 4381 was frequently somewhat closer to traditional transaction activity ... something like how many independent 4k disk operations can be handled per second. this was the point of my old claimed that disk technology had a ten times relative system thruput decline in roughly a 15 year period between late 60s and early 80s.

the disk transfer rate has gone up significantly ... but the increase in 4k accesses per second hasn't increased that much. can two current 20gbyte disks do more 4k operations per second than 16 3380 disks.

in part, the programming and use patterns over the last 20 or so years have had to change to accommodate the change in the relationship of relative thruput of different parts of system (lot more attention to caching and large contiguous block transfer).

3380 had avg. access of 16mills (arm+rotational delay) ... you might have current drives at 1/2 to 1/4th that ... so two current drives would have 4-8 times thruput of a single 3380 ... but possibly only 1/8th the aggregate thruput of 16 3380 drives.

lots of govs. and financial instutions have chips under armed guards until after personalization ... and sometimes even up until delivery of the card to the end-entity. conjecture that this is at least possibly because of possible exploits involving substituting couterfeit chips for the real ones (even before chips are embedded in the 7816 carrier ... it is somewhat problematical that eyeball examination of a chip can tell real ones from counterfeit).

all the trouble with the armed guards .... making sure that a counterfeit chip can't be substituted for a real one ... and then they let a person carry it around in their wallet ... or leave it on their desk. the govs and other institutions want to know that there is some level of integrity and trust with using the method of electronic authentication. that involves some aspect about the trust and integrity of the individual components. as a result they tend to specify things like EAL5-high certifications.

some manufactur may claim that they have gotten an EAL5-high certification for a specific chip .... but that typically involves only a dozen chips. Then some claim is made that the thing that you might be carrying around in your wallet is in any way similar to the dozen or so chips that were actually evaluated. they tend to specify extremely tamper-resistant components .... lots of attention that the readers at security checkpoints haven't been compromised ... or that ATM cash machines are armored and under surveillance. That still leaves something of a gaping hole about whether the card in your hand contains a real chip or a copy chip.

There are very significant issues with regard to non-repudiation ... whether or not the key-pair was generated on-chip, is possibly one of the least significant.

In general for electronic id .... they want to know that the process has some high level of integrity and trust .... aka high-security biometric readers under constant surveillance and some degree of confidence that you can't duplicate the biometric readings. The whole issue isn't whether or not you can't (re)generate a new biometric reading (rather than the one you got at the factory) ... but whether the reading is consistently reliable. copy/counterfeit chips are somewhat similar to fake fingers or fake eyeballs or readers that have been compromised and give wrong readings.

The real issue isn't whether or not you generated your own key .... it includes whether or not the card you are presenting does really contain a chip with the acceptable integrity characteristics ... and can be trusted.

basically forget all the witch doctor mumbo-jumbo you may have heard associated with PKIs and certificates.

basically electronic-ID is authentication. authentication boils down to one or more of:
• something you have (tokens)
• something you know (secrets)
• something you are (biometrics)

chips supposedly are used in tokens to allow verification of the token to be done electronically ... and plausibly also to make it harder to counterfeit the token. The reason that gov. and financial institutions specify things like EAL5-high certification is that they really want it to be difficult to counterfeit tokens (also why they frequently have armed guards during transport from chip fabrication to personalization center).

the issue is, given the overall infrastructure, to what degree of certainty can the institution really believe its you? this not only involves things like exploits counterfeiting one or more of the three authentication methods .... but also the whole infrastructure that takes part in verifying the authentication information.

for instance, x9.84 standard for biometrics .... has issues with biometrics values .... when they effectively are used in shared-secret mode (aka central registrty, remote matching, etc) that they have the highest level of security. evesdropping a biometric value and later being able to electronically reproduce the biometric signal (as in shared-secret) opens the infrastructure up to impersonation (aka it is much easier to change a compromized PIN that it is to change a compromized thumb print).

so a real issue with buying off-the-shelf card and doing your own key generation ... has little or nothing to do with key gen ... it has to do with how can the institution trust a user presented token as part of something you have authentication (aka as in the key is suppose to be a unique representation of the token ... as opposed to the key having some unique intrinsic magical value of its own). This is in the context of institutions that nominally require armed guards as part of addressing exploits associated with copy/counterfeit chips being injected into the environment.

I would have preferred it giving me some opportunity to kill mozilla.

i've since doubled page space (which just means that it would take a little longer for mozilla to fill it up) ... and have taken to periodically killing/restarting mozilla when it seems to getting too stressed.

there were some at SHARE and elsewhere that attempted to get ibm to produce a "fast" 3380. basically it was a microcode load that only allowed access to something like 25 percent of the surface area ... resulting in better avg. arm access. The trouble appeared to be that they found that it was really only attractive to the bean counters at their corporations if it actually was priced more than a regular 3380.

The economics were somewhat ... take a $5million dollar computing installation; if you spent an extra $100k on regular disks ... and only kept each disk partially full, you could get an extra 20 percent thruput. Saving the $100k on the extra disks ... translated effectively into 20 percent overall loss (lower total system thruput) of the $5million dollar investment ... or approx. $1m.

To make it work, it had to be an official product that was marketed as a fast 3380 for more money than a regular 3380 (even tho it only had 25 percent the capacity).

the other was that half of the advanced degree graduates in technical areas were non-us.

Don't do it. Whilst RAID 5 offers a good ratio of available data to drives the write performance suffers as a result. With the current price of small drives, I don't think any one should be using it....

raid5 is norminally considered really good for read mostly. individual records can be read independently off of individual drives ... but writes requires two additional reads and an additional write

the data record (that is to be written/replaced) is first read and the corresponding parity record for that stripe is read, the original data record is "subtracted" from the parity record, the parity record is then updated with the new value to be written ... then both the data record and the parity record are written back out.

This is avoided if you are going to write all records in the stripe, then the new parity record value can be directly calculated and everything written at one time.

with cheap drives, for transaction stuff ... it is possible to just have two-way mirror ... can give twice the read thruput ... and with both drives written in parallel, is no worse than non-mirror on writes (modulo some additional bus bandwidth).

IIRC, the IBM 7090, announced c. 1959, was upwardly compatible with the IBM 709. If they were using a 709 and wanted to replace it, my guess is that they would've gone to a 7090, not a 1401, especially as a military installation. I don't think the 1401 had enough horsepower or memory to emulate another computer, nor ever had "emulator" hardware. (The IBM "emualtor", as installed on S/360, was a combination of both software and hardware. Using software alone was a _simulator_ and very slow.)

I'm pretty sure the S/360 could emulate a 709, and that the early S/370s had emulators too, so S/360 emulation wasn't necessary.

360/30s and 360/40s had ROS for both 360 architecture and 1401 architecture i.e. if you set a switch on the front panel to 1401 and put a 1401 self loading card deck into the 2540 (like MPIO) and hit the load button, the card deck would read and run.

350/50s & 360/65s had ROS for 360 architecture and 7090 architecture.

somebody has previously posted table or some 360 ROS features here within the past year or two (but can't find the reference at the moment)

I think your formula is wrong.

I've done RAID5 and gained write performance by adding drives. Your math shows the opposite.

Are you sure you don't mean T/R n instead?

(where, R is raid overhead)

Even that's too simple to be true, but it has the right implication.

raid5 write performance is four i/os compared to one i/o for non-raid(5).

you can have raid4 with all parity records on (the same) single drive ... which resultes in bottleneck on the parity drive ... basically constant performance regardless of the number of data drives. raid5 will rotate the drive with the parity record .... so aggregate performance doesn't tend to bottleneck on a single drive ... but is spread across all drives; however it is still approx. 1/4th the thruput of non-raid given distribution across the same number of drives (each write requires two reads and two writes).

possibly try search engine for raid5, raid6, raid10, etc; result with pictures/diagrams:

there were some implications ...

one) that the avg. size of the subsidies and the percentage needing subsidy were increasing over time and

Then the widgets would be tranported to Moscow and then tranported to the fifth corner of the Union for assembly. Manufacturing and assembly were not allowed to be done on the same site. Not only does that make thing more expensive, it also makes the wall clock time span of manufacturing each piece extremely long. What would take us a day to make, from raw material to finished product, would take the Russians a month or longer.

the us automobile industry had an analogous problem taking avg. of seven years from inception until car was rolling off the line. some of the problems were that after early overall design .... some of the pieces (like batteries, shocks, etc) might change size/shape and no longer fit in the original design. focus of C4 that I attended circa 1990.

other issue was that foreign competition had reduced the cycle to 3 years (aka it was possible for foreign competition to react almost two and half times faster to changing consumer habits than domestic manufactures).

I'm looking for a document entitled:

"Draft American national standard for financial institution sign-on authentication for wholesale financial systems: Secure transmission of personal authenticating information and node authentication"

It's the ANSI X9.26 specification.

electronic standards store:
http://webstore.ansi.org/ansidocstore/

and do search on x9

notice x9.26 withdrawal ...
Withdrawal of x9.26

Recommended Action:

In its July, 1999 meeting, Working Group X9F3 responsible for the maintenance of ANS X9.26, Financial Institution Sign-On Authentication for Wholesale Financial Transactions, by unanimous vote recommends that ANS X9.26 be withdrawn. This is a continuation of the action taken by X9F in its last meeting when it recommended the withdrawal of ANS X9.9 and ANS X9.23. ANS X9.26 is dependent on ANS X9.9 and X9.23 and is therefore an inappropriate standard to be used in the wholesale financial environment based on the high average dollar value of transactions.

Procedural Basis:

At its April meeting in 1999, the X9F subcommittee voted unanimously (except for an abstention of one new member) to withdraw ANS X9.9 and ANS X9.23. Subsequent to that meeting, the X9 Secretariat advised ANSI to cease all sales (paper and ESS versions) of ANS X9.9 and ANS X9.23. X9F3 also recommends the withdrawal of ANS X9.26 for the reasons stated below.

Rational for this action:

Based on recent attacks on 56 bit symmetric encryption algorithms such as the Data Encryption Algorithm (DEA), X9F at its April, 1999 meeting decided to cease support for X9.9 and X9.23. ANSI has been advised to stop selling these standards.

ANS X9.26 is also recommended for withdrawal based on the following:

1) ANS X9.26 is dependent on ANS X9.9 (MAC) for message authentication and X9.23 for data encryption..

2) There is a well known attack on MACs used by ANS X9.26 based on the availability of brute force equipment, such as the "DES cracker". This attack is published in TG-24-1999, which is available in draft form and will be made freely available on the X9 bookstore web site.

3) Given the existence of the above equipment, in the wholesale environment with average transactions of millions of dollars, the use of 56-bit keys is no longer a prudent business practice to be continued. Financial Institutions need to plan to migrate away from the use of any 56 bit symmetric encryption algorithm in the wholesale business environment.

I certainly can't speak for Oracle, but I do note that IBM provides the "coupling facility", which is a special OS, running on a S/390 type proessor (one of those on the MCM set) and provides relativly low latency locking between OS images. Also, the descendants of the Univac/Sperry/Unisys systems offer a piece of special function hardware that provides low latency inter system locking precisely for this purpose. It's use is integrated into their database software.

The fact that these vendors go to all that trouble seems to support your contention that, for the workloads they want to support, main memory caching is not sufficient, although for systems that can fit in one tightly coupled complex, tehy do, of course, use main memory for the database caches.

when i did the original parallel lock manager for ha/cmp .... random ref:
https://www.garlic.com/~lynn/95.html#13
https://www.garlic.com/~lynn/subtopic.html#hacmp

i worked out the semantics that allowed a cached record to follow the lock. some number of people are/were apprehensive because the recovery/commit logs are node specific ... and recovery in fast commit scenario can be complicated i.e. local log record(s) has been written/commuted, but the record home location hasn't been rewritten ... and the working copy is floating around different node caches.

effectively with the fast interconnects ... the I/O & processor overhead moving the lock between nodes and moving the lock plus record between nodes was nearly identical. with the record accompanying the lock, then the complex starts to look much more like aggregate large distributed memory.

the alternative is that in the case of fast commits, the record home location has to be written before the lock is moved between nodes (and the destination node reads the record off disk). An intermediate step (addressing some of the recovery complexities) is to allow forcing the write of the record home location before the lock moves between nodes ... but transmits the record along with the lock ... at least saving the destination node having to reread the record off disk.

some of this originated when my wife did her stint in pok responsible for (mainframe) loosely coupled (i.e. cluster) architecture. Her Peer-Coupled Shared Data included low latency locking protocol ... but ran afoul policy that inter-machine communication was suppose to be SNA based (she fought and lost battle that trotter should be less like emulated ctca and more like real interprocessor communication).

Note: the UNIX _block_ buffer cache can also be useless or a damn nuisance because in almost all cases UNIX applications access files sequentially, and the replacement policy for most such block buffer caches is LIFO/LRU like, which is exactly the worst possible choice for that (IIRC very few UNIX implementations actually implement 'POSIX_FADVISE_RANDOM' or similar).

An LRU block buffer cache actually works well when files are one or a few blocks long, even if block access patterns are FIFO, because then in effect it becomes a file buffer cache, and while as a rule block access within a file under UNIX is FIFO, access to files is often LIFO. When sequential access to a few large files happens, then the UNIX buffer cache as commonly implemented, especially as under Linux, is a damn nuisance.

i had something of this issue with the sheriff/3880-13 full track cache people 20 years ago. they were claiming 90 percent hit rate in the cache. however they were measuring an application having dataset formated 10 4k blocks per track and reading sequentially. the first record touched on a track would fetch the whole track and then the next nine reads would be "hits". my claim was that the application could achieve slightly better thruput by changing the parameters on the DD statement (so the system did 10 record reads in single I/O operation) and the sheriff/3880-13 hit rate would drop to zero.

35 years ago, i had 2741 going into cms. a little less than 30 years ago, i got 3270 (24x80 char) going into cms. 25 years ago, i had two 3270s next to each other on the desk with coaxs going to different system ... then added coax switch box so i could manually switch between 4 systems for each 3270 ... then added parasite, story, and pvm ....

so each terminal connection could have multiple different logical sessions to different systems.

about 20 years ago, got a pc with 3270 terminal emulator which could have multiple logical sessions and could switch between local window on the pc (say borland's tinycalc) and various 3270 sessions.

for past couple years, i've had two 21in screen, two keyboards, and two mouse ... side for side ... one going to an NT system and one going to linux system. about a month ago ... i got a switcher cable that supports single screen, keyboard, and mouse ... and uses scroll lock to toggle between the linux and nt systems.

I can have two windows per screen each window with 2-3 times as many lines as the 3270 screen ... and i have graphics background when i've minimized a window. i run close to the same environment on both linux & nt .... same browser, similar email, same usenet interface, both internet connected, etc.

the keyboard interface has had almost no changes in 35 years.

the gml i used over 30 years ago supported the embedding of other gml files (have common start, end, top, bottom, and whatever other common things i wanted across a collection of files). html i use today doesn't support embedding other html files. for instance, in the rfc index:

since one of the swap partitions had nothing behind it ... i decided to increase it from 512m to 1.5g (resulting in 2gig total).

... start
/sbin/sfdisk -l

/sbin/swapoff /dev/sda5 /sbin/swapon -s

/sbin/parted /dev/sda print rm 5 mkpartfs logical linux-swap <start> <end> print quit

/sbin/mkswap /dev/sda5 /sbin/swapon /dev/sda5 /sbin/swapon -s

/sbin/sfdisk -l

... end

check man pages for sfdisk, swapoff, swapon, and parted. parted especially warns about being very careful of what you type. basically "<start>" was original start for the original partition and "<end>" was enuf added cylinders to be 1.5gig instead of .5gig.

since i recreated the same swap partition only larger ... /etc/fstab didn't have to change.

Remember, the Volkswagen also came out of that era--the Nazis really did try to deliver on some of their promises. In fact we're kind of fortunate that Hitler had no patience.
