RE: perl script on remote server linux

[Irfan J Sayed (isayed)]

Hi,

In my case, the user with which I am executing the script is not there in 
sudoers file. So I did in the following manner.
#!/usr/bin/perl

open FILE, "server_list" or die $!;
while(<FILE>) {
    print "the host is: $_";
    chomp;
    system "ssh [EMAIL PROTECTED] /home/cgadgil/avm2.1/launchtomcat.sh"; } 
close FILE;
   if($?){ print "error \n"; exit 1;}
   else { print "success\n";}

But it says :
[EMAIL PROTECTED] test]$ perl ssh_test1.pl
the host is: 172.21.58.149
ssh: cgadgil: Name or service not known
Error

Any help

Regards
Irf

Try the code below, wish it works fine for you.

open FILE, "server_list.txt" or die $!;
while(<FILE>) {
    print "the host is: $_";
    chomp;
    system "ssh -x -t $_ \"sudo /home/tadipah/test.sh\" "; } close FILE;
