Running SSH as an executable console.

Hello,

I am trying to use conserver to connect to the SPs of some blade systems
using ssh. However I keep getting this error in the log file.

[Tue Aug 2 12:05:31 2011] conserver (6739): ERROR: GetPseudoTTY():
open(/dev/pts/30): Permission denied
[Tue Aug 2 12:05:31 2011] conserver (6739): ERROR: [nt6340-tvp540-a.uk]
failed to allocate pseudo-tty: Permission denied: forcing down

Has anybody seen this before ?

Here is the console config entry.

console nt6340-tvp540-a.uk {
include localconsole;
type exec;
exec /usr/bin/ssh -lroot nt6340-tvp540-a-sp.uk;
logfile /var/adm/console/nt6340-tvp540-a.uk;
rw nt6340-tvp540-a.uk;
}

Many thanks

Robin

Hi Robin,

give the ssh -t switch a try

-t Force pseudo-tty allocation. This can be used to execute arbi‐
trary screen-based programs on a remote machine, which can be
very useful, e.g. when implementing menu services. Multiple -t
options force tty allocation, even if ssh has no local tty.

Re: Running SSH as an executable console. [In reply to]

Are you running this on Solaris? And did you compile it? If so, did
HAVE_UNLOCKPT get defined in config.h? The problem is that it's trying
to allocate a pty locally and getting a permission problem. I'm
guessing at the HAVE_UNLOCKPT idea. Seeing the whole config.h might
enlighten things. Or there is some system-level thing blocking the
allocation...it's not even getting to the point of running ssh.

Re: Running SSH as an executable console. [In reply to]

Thanks for your reply Bryan.

I am running it on Solaris and I did it compile it :-) Looks like
HAVE_UNLOCKPT is set in config.h. I have attached the whole config.h,
if you wouldn't mind taking a look.

Do you think it has anything to do with the fact we have reached 1013
consoles?

Many thanks

Robin

Re: Running SSH as an executable console. [In reply to]

The config.h certainly looks fine. The number of consoles *could* be it.
Do you have any low ulimit values that might be hit? Or max number of
ptys being used? If 1012 consoles work and 1013 doesn't, there's some
maximum somewhere. Not sure what else I can suggest as I think it's
system-related and not conserver related (but I could be wrong, of
course).
