I use iptables with a 2.4.x kernel, but I believe you're looking for -A input -p ICMP -j DENY
-----Original Message----- From: Nikolai Sent: Friday, September 20, 2002 11:17 To: [EMAIL PROTECTED] Subject: ipchains help I have setup the following rules for my ipchains: :input ACCEPT :forward DENY :output ACCEPT -A input -j DENY -p all -l -s 127.0.0.0/8 -i eth0 -d 0.0.0.0/0 -A input -i eth0 -s 0/0 -d 0/0 -p tcp -y -j DENY -l I did an online-based scan at scan.sygate.com and everything appears to be 'blocked' except ICMP service on port 8. Can someone please help me with how to close this hole as well? Some background: my kernel is 2.4.18 (with Mandrake 8.2) I'm new to Linux/GNU in general and security in particular. Thanks Nikolai
