Hi All,

I think the problem is related to restrictions imposed by the jail.

Please advise.

This is because you haven't been allocated a pty inside your jail.
Enable sshd inside your jail, ssh to your jail (which will allocate you
a pty). Then from inside your jail, you can use any pty-using
application you wish.

I am presuming you are doing something like 'jexec 1 /bin/csh' or
similar, and I'm only really repeating Xin Li's advice to me[1].

Cheers

I'm chiming in to signal a possibly related problem. Logging in
and out via sshd behaves normally (ie: the ptys are cleaned up
accordingly) but opening virtual consoles in screen and then closing
them does not, thus leading to starvation.


I can confirm this also occurs in our jails on 6.2-RELEASE-p5.
