I am trying to SSH into a remote machine and execute a shell script. So far I can access the machine and I can run basic administrative commands such as, pwd, ls ,df -h, but when I attempt to use sh, perl, or any of the SGE commands (qsub, qstat) my script fails. Ideally I want to use the SGE commands directly, but I would be happy if I can get a shell script to run and thereby accomplish what I need to do (check status of a job and hopefully one day actually submit a job).
Any help is greatly appreciated.
Below is my existing script:
my $server="400.800.400.800"; #not a real IP address
#my $command="df -h"; #this worked
#my $command="ls"; #this worked
#my $command="sh status.sh"; #Received error Use of uninitialized valu
+e $stdout in string at ssh.pl
#my $command="/usr/bin/sh status.sh"; #Received error Use of uninitial
+ized value $stdout in string at ssh.pl
#my $command="qstat"; #Received error Use of uninitialized value $stdo
+ut in string at ssh.pl line
my $command="pwd"; #this worked
my $ssh = Net::SSH::Perl->new("$server", protocol=> 2, port=>"$port",
my($stdout, $stderr, $exit) = $ssh->cmd("$command");
