It seems that the SSH server is closing the connection after the first request. It may be a limitation of the device you are connecting to (unfortunately it is not to unusual to find defective SSH implementations in network devices and other embedded systems).
Just to be sure that this is the problem, ask the module to run the master ssh client in verbose mode:
$ssh = Net::OpenSSH->new($host_ip, user => $user, password => $passwor
+d, master_opts => '-vv');
Also, add an error check after the
capture call:
my @output = $ssh->capture($_);
if ($ssh->error) {
print STDERR "capture failed: " . $ssh->error;
}
else {
print @output, "\n";
}
