Hi > [root at localhost root]# chkconfig --list iptables > iptables 0:off 1:off 2:on 3:on 4:on 5:on 6:off It means that in run levels 2 3 4 5 iptables runs at boot. Your computer *probably* boots to either run levels 3 or 5. If it boots to a terminal window, its 3, if it boots to a graphical environment its 5. Hamster
