Has anyone ever run dual ethernets under ISC2.2? I've got it working, but only if I avoid IRQ 7. (Yes, I turned off lp, and anything else that wanted to use IRQ 7.) Does anyone know why I can't get a WD8003E or 3COM Etherlink II to work at IRQ 7? Is this an ISC bug or is there something magical that one must do for ISC that one doesn't have to do for ESIX? (Kudos to ESIX on their dual ethernet support -- it all just works when you install it, rather than having to edit a bunch of files and grunge around -- unfortunately, we just had to have faster networking.) Another question regarding stune parameters -- if anyone has installed/used dual-ethernets, what did you set your streams parameters to? I've tried various incantations -- some work better than others. The default parameters for an 8Mb system allow, count 'em, 0 rlogin sessions to occur. As the system is installed (no 8Mb changes from kconfig) about 3 rlogin sessions can be started until it chokes. The current settings, (which came for ISC tech support, but they've never tried this before and are just sending me what they've got on their single ethernet, 9Mb system), seem ok, except that periodically, for no known reason, a stream will hang. Not exactly something we can afford. So, if ANYONE can help, I'd be much obliged.

A 3c503 and a WD8003 do work however. But you have to edit the config files and /etc/netd.cf yourself. No big deal, but a small hassle. >before and are just sending me what they've got on their single >ethernet, 9Mb system), seem ok, except that periodically, for >no known reason, a stream will hang. Not exactly something >we can afford. There's a fix for the hanging streams. I haven't run it long enough to be sure it really fixes the problem, but it appears to so far. Posted here 'cause I'm sure others have questions about this problem. It's been there since at least 2.0.2 (first one I used TCP/IP heavily with). -- Karl Denninger (karl@ddsw1.MCS.COM, <well-connected>!ddsw1!karl) Public Access Data Line: [+1 708 808-7300], Voice: [+1 708 808-7200] Copyright 1991 Karl Denninger.

This is true, but see below. >there is a 17 page paper called "setting up a gateway on a 386/ix >system with hdb tcp" by Kevin Haley and John Antypas. on page >three (ff) it goes into detail about installing a second ethernet >board of the *same* type. i won't type in those four pages now, >you should be able to get this doc from ISC. the original >poster should get it also, it tells you everything you need to >setup a gateway. Have YOU done it with two 3c503s? If not, then I suggest you try. You'll find that it doesn't work. ISC has admitted to this. I have read, and used, the instructions you mention. They're in the 2.2 ISC manuals. Two WD cards, or one WD and one 3c503 card, work fine. Two 3c503s do NOT work. In any case, you do have to set up the files by hand. I'm not sure of the reason for the problem but I will note that the 3c503 can use DMA..... and it appears you can't change the DMA channel! Perhaps the ISC driver uses that mode (the 503 has three operating modes). Try it sometime with two 503s. -- Karl Denninger (karl@ddsw1.MCS.COM, <well-connected>!ddsw1!karl) Public Access Data Line: [+1 708 808-7300], Voice: [+1 708 808-7200] Anon. arch.
