Has anyone successfully run slip on an RT (preferably running AOS, but AIX info is welcome as well)? Anything to look out for? I'm looking for any kind of info I can get. Thanks in anticipation, Chet Ramey -- Chet Ramey "We are preparing to think about contemplating Network Services Group, CWRU preliminary work on plans to develop a chet@cwjcc.INS.CWRU.Edu schedule for producing the 10th Edition of the Unix Programmers Manual." -- Andrew Hume

I'm looking for any >kind of info I can get. Async support in the stock Dec 88 release of AOS is completely bogus-- you'll lose characters all over the place, making SLIP essentially useless. The fixes posted to comp.sys.ibm.pc.rt (and available via UUCP from ibmsupt) are said to correct this. Also, the Sep 88 kernel works OK. You'll want to use the buffered async board, in my experience, if you're running at 9600 baud or 19.2kb--the older unbuffered board and the planar ports lose characters regardless of the AOS revision. Once you have this settled, SLIP works fine. I had to hunt down on UUNET slattach.c and compile and install it as /etc/slattach, since I didn't see it in the distribution (maybe I messed up, I dunno.) I've been running for almost a year with a SLIP connection at 19.2kb. -- Steve Dyer dyer@ursa-major.spdcc.com aka {ima,harvard,rayssd,linus,m2c}!spdcc!dyer dyer@arktouros.mit.edu, dyer@hstbme.mit.edu

I asked this one about 2 months back and lot's of people said `If you find one let me know' but nobody said they had a version that worked (I was looking for AIX version for RT and/or PS/2). If somebody has done a slip version for AIX and it is not based on licenced code how about posting it ? -- John Pettitt UUCP: uunet!slxsys!jpp Internet: John.Pettitt@specialix.co.uk POTS: +44 1 941 2564 FAX: +44 1 941 4098 Disclaimer: Me, say that ?

I'm looking for any kind of info I can get. I'm running SLIP on RTs running Mach 2.5. I'm told that the AOS drivers are (largely?) what's in Mach. I discovered a fencepost error in the latest SLIP driver, what amounts to an off-by-1 error in slinput() because it checks for noisy line packet overrun via (count >= SLMTU) rather than (count > SLMTU). A new Mach kernel with the 4.3-tahoe SLIP driver is working fine so far, but I have to do some more testing before I'm fully convinced. The async port driver on this system is deeply braindamaged. I get error messages on the console such as "asy0: overrun error" and "slih6: undefined bit(s) in softlevel: 4" down to speeds as low as 1200bps. The fact that the system wastes time chattering these messages onto the console makes the problem worse. I've done a rude thing with Emacs to put a ^@ at the beginning of these messages, so I don't see them any more. --Karl

At least one of my customers have successfully set up SLIP on AIX/RT V. 2.2.1. I can't answer if there were things "to watch out for", but I asked him if it worked and he said yes. It's not being used in a "production" environment, he just set it up to try it. If you are having problems *with AIX* on this, please call your local IBM Branch Office. If that doesn't work, call me.

I haven't tried it, but AIX/RT 2.2 and above support SLIP already ... no porting should be required.

The problem is that the asynchronous support shipped in December '88 did not work. This problem is fixed by fix V1.3. With fix V1.3, SLIP works at 19200 bps. Here are the things you need to do to set it up: Make sure the psuedo device "sl" is in your kernel config file (It is in "GENERIC"). Compile slattach (find it in /usr/src/etc). login using tip or kermit or whatever. put this in the background with control/z. on each host: /etc/slattach tty speed (e.g. slattach tty01 19200) /etc/ifconfig sl0 inet source destination options.
