Unable to ssh in linux box

pinnacle has asked for the wisdom of the Perl Monks concerning the following question:

I am unable to ssh into *nix box, it always says: "Net::SSH: Bad host name: tic-rhel5-20-12" when I check hostname on box it says

[root@tic-rhel5-20-12 ~]# hostname
tic-rhel5-20-12
[download]

CODE:

#!/usr/bin/perl

use Net::SSH::Perl;
use strict;

my $host = "tic-rhel5-20-12";
my $user = "ssh root\@10.10.20.12";
my $passwd = "test";
my $cmd = "ls -l /root";

my $ssh = Net::SSH::Perl->new($host);
my $ssh->login($user,$passwd);
print "looking...";
my ($output, $error, $exit) = $ssh->cmd("$cmd");
print "Result:\n";
print $output;

Try `hostname -f`. The domain part is missing.	[reply] [d/l]

`[root@tic-rhel5-20-12 ~]# hostname -f tic-rhel5-20-12` [download] It still gives same hostname on the box	[reply] [d/l]

I recently changed providers. Everything works, but the provider insists on muscling-out "localhost". The result is that when I try to use a ssh module, it comes back with "Bad Hostname". Make sure that localhost is working, or use your host's info.	[reply]

Reply to all I tried "uname -n" it still gives "tic-rhel5-20-12" localhost is working fine I escaped `my $cmd = "ls \-l \/root";` Still same error Net::SSH: Bad host name: tic-rhel5-20-12	[reply] [d/l]

It works for me now, I troubleshooted myself, I changed the hostname to actual "ip address" and username to just "root" it worked for me	[reply]

Try "uname -n" to get the name. Under some OS's it will return just the hostname. On others, it will return the FQDN.	[reply]

Do you need to escape the '-' ?	[reply]
