I have a Challenge S (basically an Indy without audio and video) which a major medical center here used as a router and fileserver until last year. They only gave it up because it was the last piece of 10baseT networking gear in the house, and the Challenge's external SCSI was all HVD.

Given an additional NIC and a proper IPfilter installation, I expect an Indy would make an OK router. It would be a lot more fun as a workstation, though.

I've seen that statement in several places, but I've been running a -104 IO4 board with R10K processors in my Challenge L for a couple of years.

Do you know what sort of problems are supposed to occur if you have a pre-107 IO4 with R10Ks? I had some problems earlier this year, but none were traceable to the -104 IO4, and it's still in there.

Currently the machine's running six R10K processors, 3 GB RAM on two MC3s, the -104 IO4 board, a full complement of internal SE SCSI drives and an external DLT tape, and doing Just Fine.

The system will not see all the processors and it is driving me nuts. I don't think it is the board or the procs, I think it may be the carriers. If anyone has the time and machine, I am willing to ship the board to you for repair. Please let me know if anyone is interested.

Your best bet is probably just to buy a good IP25 off eBay or from some other Nekochaner (Nekochaniste? Nekochanoid?).

I've got a couple of duff ones myself: a 2-CPU one that gives the occasional panic, and a 4-CPU one that I ran for a couple of years before it ate its voltage regulator. I'm tempted to try to combine the two into one good board, but haven't tried it yet.

You can control Postfix's idea of what your local network is, and, unless you specify addresses that aren't really on your network, it's bulletproof in my experience. Postfix (since pretty early versions) rejects relaying by default. It's posible to override this with configuration, of course.

If you continue to have trouble, join the Postfix mailing list at http://www.postfix.org . Read the membership welcome notice carefully before posting.

Why it isn't part of the Postfix base package is kind of a mystery to me, tho. Seems like almost everyone is travelling all over with a laptop these days. Postfix is definitely fast. Mikey likes that part !

Since Postfix doesn't do POP at all, Postfix's including a hack like pop-before-smtp would be pretty tough.

The real thing is to use a supported authentication method. However, they seem to be moderately difficult to implement, since they are a compile-time option with Postfix, etc. Once implemented, both on the client and the server, however, they are user-transparent.

Because I have a relatively small number of traveling users, and they are tech-savvy, I use a home-brew combination of split-horizon DNS and SSH tunnelling to provide remote access. The advantage to this method is that I can allow out-of-LAN access to a number of otherwise local services. The disadvantage is that the user has to affirmatively put his machine into "traveling" mode when he leaves the LAN, and put it back into "local" mode when he returns.

I don't know about Exabytes, but I've had no problems at all using various DLT drives on both Sun and SGI machines; I've plugged them in and they Just Work.

Folks-

It looks like WinXP and I are going to reach EOL together; after a 20-year battle with cancer, I've signed up for in-home hospice care.

As a result, I have a pile of SGI and associated equipment I'd like to pass along to someone who can still use it.

It's a large pile:

SGI Indigo2: Purple R10k-195, MaxImpact, 768MB RAM, nice plastic, IRIX 6.5.22. Battery is dead, but it will boot through the maintenance menu.

SGI O2: Mid-range spec, but I think it has the high-end A/V module. IRIX 6.5.30, boots and runs fine. Plastic good except CD-ROM drive door missing.

SGI Octane: Single processor, dual graphics modules, good plastic, IRIX 6.5.30.

External peripherals: About a dozen Sun and SGI external cases (411, 611, etc.) suitable for all sorts of SCSI devices. Some open-face, some closed, etc. I think there's an SGI SCSI floppy drive in a granite case.

Cables: A large collection of external SCSI cables.

Drives: A bunch of those, too, including some 36 GB SCA drives.

Parts, books: Yep. A couple or three Granite keyboards and mice. Large box of IRIX installation CDs. Much etc.

I'd love for this to go together. I can't ship it; it's SGI stuff, it weighs a ton, and I'm not really in shape to take it anywhere. It'll all fit in a station wagon; getting it in a compact sedan might be a challenge.

Contact me off-list to arrange pick up on Bainbridge Island, across Puget Sound from downtown Seattle.

Thanks.
