[net.micro.att] Layered shell on 3B2; help please

msc_wers@jhunix.UUCP (Edward R Scheinerman) (01/09/86)

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.

	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.

Recently I posted the following question:

and received many responses by mail. The following,
however proved the most helpful and I thought I'd share it:

Thank you Randy, and thank you to all the others who responded.
My 3B2 is feeling much better now.
