Time out set in perl script
Hi,

I am preparing a perl script, which will run some commads on remote Linux servers.

I have a file contains all the servers names one by one like below

vi servers.txt

srv1
srv2
srv3

Now, I need to prepare a perl script to ssh (or)rsh to each server in the above file and get the uptime.

but the issue is, if the server is pinging and not able to ssh or rsh, then the script is getting hung.

can anyone suggested me to fix this, without using any perl modules.

here is my script

Code:
 
 #!/usr/bin/perl 
 use strict;use warnings;
  
 open (DATA, "<servers.txt") or die "no file, $!";
@srv = <DATA>;
close (DATA);
  
 $cmd = 'uptime';

 foreach $i (@srv) {
        chomp $i;
         $up = qx/rsh $i '$cmd';
         print " $i $up";
          }
 exit(0);

here the problem is, if the server is pinging but not able to login, then the script is not moving to another server.

please suggest me.
