Firewall error

Can someone explain where to look to solve the following error: root@zues:/home/mlong > /sbin/init.d/rc.firewall status depmod: *** Unresolved symbols in /lib/modules/2.2.16/pcmcia/mpsuni_cs.o Try `/sbin/ipchains -h' or '/sbin/ipchains --help' for more information. I do not understand what this is trying to tell me. Thanks, Mike
