[Ssh-sftp-perl-users] Detecting connection closed by server.

[Enrique de A. S. <enr...@pc...>]

Hi,

I'm doing a little program which sends command to anothe machine 
periodically. The code of this program is basically the next one:

my $ssh = Net::SSH::Perl->new($host, protocol => 2, compression => 1, 
debug => 1);
$ssh->login($user, $pass);

my $i;
for ($i=0; $i<10; $i++) {
	print "Iteration $i\n";
	my ($out, $err, $exit) = $ssh->cmd("ls");
	print ($out, $err, $exit, "\n");
	sleep 60;
}

I'm using SSH-2 to avoid authenticate myself each time I send a command 
(it's very important for me because time reasons).

I have next problems, sometimes it's possible that ssh server close SSH 
connection. Then, requests sent by the client has not response, but it 
is unable to detect it.

Has anybody any idea about how to detect that server has closed the 
connection?

Thanks in advance,

Enrique.
