#!/usr/bin/env perl

use Net::Telnet;

print "reporting end of web server log files:\n";

my($input_log, $output_log, $dump_log);
$input_log="./input_log.log";
$output_log="./output_log.log";

the command gives back a 6 digit string like 123456. de content of the dump_log is > 0x00000: 67 65 74 20 63 6f 6d 6d 73 0d 0a get comms.. < 0x00000: ff fd 03 ff fe 01 ff fb 01 ÿý.ÿþ.ÿû. Any idea?
