Simple perl program failing to execute
- by yves Baumes
Here is a sample that fails:
#!/usr/bin/perl -w
# client.pl
#----------------
use strict;
use Socket;
# initialize host and port
my $host = shift || 'localhost';
my $port = shift || 55555;
my $server = "10.126.142.22";
# create the socket, connect to the port
socket(SOCKET,PF_INET,SOCK_STREAM,(getprotobyname('tcp'))[2])
or die "Can't create a socket $!\n";
connect( SOCKET, pack( 'Sn4x8', AF_INET, $port, $server ))
or die "Can't connect to port $port! \n";
my $line;
while ($line = <SOCKET>) {
print "$line\n";
}
close SOCKET or die "close: $!";
with the error:
Argument "10.126.142.22" isn't numeric in pack at D:\send.pl line 16.
Can't connect to port 55555!
I am using this version of Perl:
