I am having a devil of a time and would appreciate any help from experienced folks -- IBM's customer support ain't what it's cracked up to be! I am attempting to set up a network using a single RT and several PC ATs running X on DOS software, all using ethernet connections. Following the guideines in the Communications cookbook, I diddled all the relevant files (at least I THINK I did), and recompiled the kernel. One particular problem is that, when attempting to "ping" or otherwise make network contact with another host that is not on the net, I get a diagnostic message: net0: transmit timeout -- device shutdown !@#$!@!!!! This is plain annoying! After this happens, the easiest thing to do is reboot! The network is "unreachable" after this! Also, the XONDOS software seems not to work -- it sets the host addresses correctly for their Internet address, but thinks that the local host's ethernet address is 00 00 00 00 00 !!!! I would love to hear from anyone regarding: - TCP/IP services on the RT (running at the same time as X11) - X Windows for DOS Software (we're using 3COM boards, all of which work just fine talking on the ether to each other!) - Making the above two work together! An seemingly unrelated but vexing problem is that, upon rebooting (after a shutdown, of course) the f***ing login: doesn't recognize any login names (including 'root'). The only thing to do is reboot again, interrupt, which puts us in maintenance mode, and exit -- strangely, when multi-user mode is started again, it recognizes my login !!!! hooray! but what is happening?? Anyone else regret going with AIX?? I'd be happy to be made a fool of if it makes these problems go away! Thanks for your support! m sierchio -- {apple, pacbell, hplabs, ucbvax}!well!gors gors@well.sf.ca.us (Doolan) | (Meyer) | (Sierchio) | (Stewart)

This looks like the same problems we've encountered here dozens of times. Perhaps this shoudl be a monthly posting :-). Anyway, it looks like you forgot to use the devices command to set the memory addresses correctly. The parameters you want to change are rsa (98000), rea (99fff), brsa (9a000), and brea (9ffff). The parens are my values. The default values are just plain wrong (typical IBM). You also need to set the interrupt level to 3 and the frequency to every 18.3ms. You also need to set the jumpers on the board properly. For the above values the settings are as follows... The interrupt level is right above the edge connector. Set it to three. The memory address jumpers are w10 to w13. Set them to horizontal, horizontal, vertical, vertical. Sort of _ _ H H The interrupt frequency is w14 and should be set at position 2. I'm sorry I can't be more exact, but the positions are hard to explain. If you have the red "User Setup Guide and Options Installation book it's in there under network adapters. Good luck. >Also, the XONDOS software seems not to work -- it sets the host >addresses correctly for their Internet address, but thinks that the >local host's ethernet address is 00 00 00 00 00 !!!! Check /etc/rc.tcpip You need the host command in there and the name used must match the /etc/net name and the name in the hosttable. Also, fixing the jumpers as above might help. >Anyone else regret going with AIX?? I had no choice (it was free, so we took it) but I think I'd prefer a "real" Unix. db ________________________________Daniel Barron__________________________________ ______________________________________ ________________________________________ "There are four types of homicide: | E-mail: barron@eniac.seas.upenn.edu felonious, excusable, justifiable | barron@wharton.upenn.edu and praiseworthy." --Ambrose Bierce | barron@dacth01.bitnet ______________________________________|________________________________________

I suppose you know by now, but I doubt that your baseband adapter's jumpers are the whole problem. I don't think you'd be able to talk to the net at all with default settings on both the card and in the software. The card comes jumpered to use memory starting at 98000 hex; the default in /etc/ddi (used by devices) is 80000. >I would love to hear from anyone regarding: > > - TCP/IP services on the RT (running at the same time as X11) They get along fine here. I don't know anything about XONDOS. >An seemingly unrelated but vexing problem is that, upon rebooting (after >a shutdown, of course) the f***ing login: doesn't recognize any login >names (including 'root'). The only thing to do is reboot again, interrupt, >which puts us in maintenance mode, and exit -- strangely, when multi-user >mode is started again, it recognizes my login !!!! hooray! but what is >happening?? What's in your /etc/.init.state file? It should be one character (and a newline), probably `a' for `automatic multi-user' or `m' for `maintenance' (single-user mode). This letter gets passed as an argument to /etc/rc to determine the run level on boot. Documented in chapter 3 of the Operating System Technical Reference (assuming you're running an RT). >Anyone else regret going with AIX?? Not me. Our systems are fast and reliable. The Berkeley stuff that's been integrated into the system is really a part of it, not a pile of scabs and patches, and it's true to the way the stuff works on BSD-based systems (except for symbolic links, but I don't really want to get into that now... ). *-*-*-*-* Things to do to get a network node going: - Edit /etc/hosts. You don't need a `localhost' entry for loopback; the local system is just another name in the list. - Edit /etc/hosts.equiv. - Edit /etc/rc.tcpip (to set the host name at boot time) - Edit /etc/rc to uncomment the invocation of /etc/rc.tcpip - Edit /etc/net. Comment out or remove the token ing entry unless you're running token ring. - Run `devices' to add net0 (driver for the baseband adapter). - Use the `devices' command to make ptys, some with gettys and some without. If you need more than 16 ptys, bump the value of `ptybuffers' in /etc/master and make a new kernel, and edit /etc/ddi/pty to make more blank entries for use by devices. IBM people say they're going to provide a batch program to create devices; for now, it's all interactive and somewhat tedious. - To run X on an RT, you need at least 8 megs of memory. For running X, there are some resource limits in the kernel that should be bumped upward. The ones I changed were ptybuffers (from 16 to 32) charlists (64 to160) maxminor (in the `uptc' and `upts' stanzas; 16 to 32) procs (in `sysparms'; 60 to 90) filetab (250 to 350) inodetab (250 to 350) Chuck Karish {decwrl,hpda}!mindcrf!karish (415) 493-7277 karish@forel.stanford.edu

As there are two (or more according to recent commentaries) distinct operating systems which are germaine to this newsgroup, marking which one would help me not read what I can't fix or comment knowingly upon. Inserting "AIX" into the keywords or subject line would do the trick. Thanks, and I don't have an AIX box to play with... Eric Eric Brunner uunet!ibmsupt!brunner
