Question:

A perl program that was using SSH to run on a remote machine errors out because of an update in the warning message at login. The script interprets the following as STDERR and stops executing.

################################################################################

Before they added this message the script was working fine…any ideas?

Solution:

I’m assuming that the ssh_cmd is the part that is failing.  Is this correct?
From the documentation, it doesn’t look like there is any way to handle it if the data appears on STDERR.

You could try the Net::SSH::Perl module, and use the command:
my($stdout, $stderr, $exit) = $ssh->cmd($cmd);
which allows you to run a command, and capture the STDOUT and STDERR seperately.

Or instead of using the ssh_cmd, use sshopen2 (as you are), but then print to WRITER the commands you want to execute.
