Scratching my head with an issue where my Perl CGI output is being
truncated, however when running directly from the command line it
works. I've tried apache2 without any chance.

Below is a minimal version of a script I'm useing to pull info from a
Cisco router and display in the web browser:
---
#!/usr/bin/perl -w

use strict;
use CGI ':standard';

my $output;

print header;
print start_html('Test');
print h1('Testing...');

$output = `rsh <cisco_router> ping <ip_addr>`;
print "<pre>$output</pre>";

print end_html();

exit;
---

The problem being the output is being truncated:
---
Testing...

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to <ip_addr>, timeout is 2 seconds:
!
---

Missing:
---
!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 4/4/8 ms

I'm running:
# perl -v
