Hi monks, I have a subroutine, in which user gives a server_list_array which containts the list of server ips. I then look through each server name, telnet and try to login. If it is a faliure, I make that line in server_list_array null(""). Later I can grep {\S}, @server_list_array to remove the failed servers. Am attaching the code, but the script dies when a server is encountered to which I cannot telnet, even though Errmode is set to 'return'. What is wrong here? 
sub server_test_routine {
    for $i (0..$#SERVER_LIST_ARRAY) {
        $server_name = $SERVER_LIST_ARRAY[$i];
        chomp($server_name);
        $server_status = 0;
        $server_test = Net::Telnet->new(    Timeout => 10,
                                            Prompt => '/]/i',
                                            Host => $server_name,
                                            Errmode => 'return');
        print "Server $server_name returned $server_test\n";
        $server_status = $server_test->login(Name => $username,Passwor
+d => $password,Errmode => 'return');
        $server_test->close;
        if (!$server_status){
            print "Rejecting server $server_name, cannot telnet\n";
            $SERVER_LIST_ARRAY[$i] = "";
        }
    }
}
