Hi Monks,

First off, I'm not a competent Perl coder, so please forgive me if this is obvious....

I'm trying to get the following code to execute two commands on a remote machine using Net::OpenSSH. I can login and execute the first command ok, but the second command simply returns "Connection to x.x.x.x closed by remote host." By introducing a delay before the 2nd command and looking at netstat I can see that the connection is still open, right up until the second command is attempted. In fact netstat looks like: 

netstat -an | grep x.x.x.x
tcp        0      0 x.x.x.x:55942       x.x.x.x:22           ESTABLISH
+ED 
unix  2      [ ACC ]     STREAM     LISTENING     7356830 /home/cstron
+g/.libnet-openssh-perl/root-10.224.138.142-26229-724671

Is it even possible to execute two commands without opening two connections to the remote machine? Where am I going wrong?!

Thanks Monks! 
#!/usr/bin/perl

use Net::OpenSSH;

$ip="x.x.x.x";
$user="xx";
$pass="xx";

($ssh)=&connect_ssh($ip, $user, $pass);  

@arry = $ssh->capture("ps -ef");


while (@arry)
{
 $line=shift @arry;
 print "MATCH1 $line";
}


@arry = $ssh->capture("ps -ef");


while (@arry)
{
 $line=shift @arry;
 print "MATCH2 $line";
}


sub connect_ssh
{
 my $ip = shift;
 my $user = shift;
 my $pass = shift;
 my $ssh = Net::OpenSSH->new(   $ip,
 strict_mode => '0',
 user     =>     $user,
 password =>     $pass,
 timeout  =>     '60');
 return ($ssh);
}

By the way, I know running twp "ps -ef" is pointless, but I'm just trying to illustrate the fact that I can't get a second command to run.

I have openssl installed and normal ssh works perfectly fine.
