Ok, fair enough.

Well the rest of the code _only_ does the telnet part and has too much
hardcoded stuff atm. It works perfectly as per cpan docs.
I'm just stuck on formatting the sub to match a string, just don't know
enough about Perl:)
I think I have it:
sub parse_output {
my ( $string, $match ) = @_;
die "Error in parse_output sub\n" unless ((defined $string) || (defined
$match));
if ( $string =~ /$match/ ) {
return "OK";
} else {
return "CRITICAL";
}
}
$status = parse_output($output, $expect);
print "Status: $status\n";
>From what I can see, this follows all the suggestions you have provided?
Thanks for all your help!
