I have a script that loops through a file of ip addresses and pings them. If the ping is successful, it rsh's to the machine and runs a command. I am using Net-Rsh-0.02. Here is some debug output: Errno::EADDRINUSE(/usr/local/perl/5.6.1/lib/5.6.1/sun4-solaris/Errno.pm:153): 153: sub EADDRINUSE () { 125 } DB<1> Errno::FETCH(/usr/local/perl/5.6.1/lib/5.6.1/sun4-solaris/Errno.pm:182): 182: $errno = 0 unless $! == $errno; DB<1> Errno::FETCH(/usr/local/perl/5.6.1/lib/5.6.1/sun4-solaris/Errno.pm:184): 184: return $errno; DB<1> Net::Rsh::rsh(/usr/local/perl-v5.6.1/lib/site_perl/5.6.1/Net/Rsh.pm:42): 42: if($!{EADDRINUSE}) { DB<1> Carp::croak(/usr/local/perl/5.6.1/lib/5.6.1/Carp.pm:119): 119: sub croak { die shortmess @_ } DB<1> Carp::shortmess(/usr/local/perl/5.6.1/lib/5.6.1/Carp.pm:109): 109: { local $@; require Carp::Heavy; } # XXX fix require to not clear $@?

sub runCommands {
  $a=Net::Rsh->new();
    $host="$ip";
      $local_user="root";
        $remote_user="root";
          $cmd="/home/admin/master/pushout/scripts/$program";

  if ( defined($a) )
    {
      $status = $a->rsh($host,$local_user,$remote_user,$cmd);
        if ( ! defined($status) )
          {
            $msg = $rsh->errmsg;
              print "\t$msg\n";
               print LOG "\t$ip\t$msg\n";
                 $rsh->close;
               }
      else
       {
         print PING "$ip  $hostname\n";
            # Run the program
           $a->rsh($host,$local_user,$remote_user,$cmd);
             sleep 1;
           }
    }
  else {
    print "\t$ip\tConnection refused.\n";
      print LOG "\t$ip\tConnection refused.\n";
    }
}

Any ideas? It barfs after successfully rsh'ing to 5 hosts.
