NAME

Net::Telnet::Netscreen - interact with a Netscreen firewall

SYNOPSIS

use Net::Telnet::Netscreen;

my $fw = new Net::Telnet::Netscreen(host=>'192.168.1.1'); $fw->login('admin','password') or die $fw->error; $fw->enter_vsys('wineasy.no'); print "We are now in: ".$fw->current_vsys."\n"; my %vsys=$fw->get_vsys; foreach $key (sort (keys %vsys)) { print $key,'=', $vsys{$key},"\n"; } print @results;

DESCRIPTION

Net::Telnet::Netscreen is mostly a pure rippoff of Net::Telnet::Cisco, with adaptations to make it work on the Netscreen firewalls. It also has some additional commands, but for basic functionality, see Net::Telnet and Net::Telnet::Cisco documentation.

FIRST

Before you use Net::Telnet::Netscreen, you should probably have a good understanding of Net::Telnet, so perldoc Net::Telnet first, and then come back to Net::Telnet::Netscreen to see where the improvements are.

Some things are easier to accomplish with Net::SNMP. SNMP has three advantages: it's faster, handles errors better, and doesn't use any vtys on the router. SNMP does have some limitations, so for anything you can't accomplish with SNMP, there's Net::Telnet::Netscreen.

METHODS

New methods not found in Net::Telnet follow:
