Hi, I tried to apply: okidz:~# iptables -m iplimit -I INPUT -p tcp --dport 23 -j DROP --iplimit-above 3 Unfortunately, I had this: iptables: No chain/target/match by that name Kernel version 2.5.18, iptables 1.2.3. What's wrong? Thanks in advance, Oki -- To UNSUBSCRIBE, email to debian-user-request@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmaster@lists.debian.org
