Description Glen Lapham 2002-06-03 15:21:54 AEST

I'm running OpenSSH v3.0.2 on MP-RAS. I am having problems running ssh by cron.
I can run a script from the command line which executes ssh and does a simple
'who' on the remote system (running OpenSSH v3.1).  The script is:

/usr/local/bin/ssh <user@host> "who"

When I run it from cron, I get the error:    select: No such device or address
I turn DEBUG3 on and get the following just before the above error:

debug3: channel_close_fds: channel 0: r 6 w 7 e 8
debug1: fd 0 clearing O_NONBLOCK
debug1: fd 1 clearing O_NONBLOCK
debug2: fd 2 is not O_NONBLOCK

It seems to be a file descriptor problem when it is freeing fds.

In the crontab,  I have tried  /usr/bin/ksh and /usr/bin/-ksh.  Same thing 
happens.  Have also tried v3.2.2 and used the -T option. No luck. 

Has anyone encountered this before on any OS?

Glen
