Re: [Ssh-sftp-perl-users] Problem using Net::SSH::Perl

[rkb@i.frys.com]

Try checking the exit code of the command.

my ($stdout, $stderr, $exit) = $ssh->cmd("service snmpd start");

if ($exit != 0 {
   warn "An error has occured - exit code:$exit\nerror message:$stderr";
}
else {
   print "ssh command succeeded - Good Bye";
}
