When I invoke the "layered shell" shl on my ATT 3B2 computer I receive the following error message: no control channels available (errno=6) What does this mean and how can I fix it? Thanks. -Ed Scheinerman Dept Math Sciences Johns Hopkins Baltimore, MD 21218

Do you have all of the pseudo tty's installed in /dev? That is, all of the /dev/sxt___ devices? And do they have a default permission of 622? I would guess this to be your problem area. ==> Larry Lippman @ Recognition Research Corp., Clarence, New York <== ==> UUCP {decvax|dual|rocksanne|rocksvax|watmath}!sunybcs!kitty!larry <== ==> VOICE 716/741-9185 {rice|shell}!baylor!/ <== ==> FAX 716/741-9635 {G1, G2, G3 modes} duke!ethos!/ <== ==> seismo!/ <== ==> "Have you hugged your cat today?" ihnp4!/ <==

Recently I posted the following question: > When I invoke the "layered shell" shl on my > ATT 3B2 computer I receive the following > error message: > > no control channels available (errno=6) > > What does this mean and how can I fix it? > Thanks. and received many responses by mail. The following, however proved the most helpful and I thought I'd share it: -> HA!!! I was bit by this a while ago and it drove me up -> a wall!! I had been running shl just fine. And then it went -> away. Turns out I had a partial system crash, and did a -> partial restore from the original floppies. The gotcha -> is that there is a file /etc/system, that has to have the line -> INCLUDE: SXT -> in it. This line gets removed in a partial restore! -> Just edit that file, add that line and do a cold boot from -> erom. Instead of answering unix to the question of which file -> to load off the hard disk, say '/etc/system' -> Good luck. -> -> -> --- -> .. that's the biz, sweetheart... -> Randy Suess -> chinet - Public Access UN*X -> (312) 545 7535 (h) (312) 283 0559 (system) -> ..!ihnp4!chinet!randy Thank you Randy, and thank you to all the others who responded. My 3B2 is feeling much better now. -Ed Scheinerman
