I need to add u32 match capability to my iptables. Can anyone tell me how? I would like to: iptables -I RH-Firewall-1-INPUT -p udp -m length --length 39 \ -m u32 --u32 "27&0x8f=7" --u32 "31=0x527c4833" -j DROP And the error returned is: Couldn't load match litipt_u32.so: cannot open shared object file: No such file or directory I notice that the extensions/libipt_u32.c isn't being built into a .so during the make from my 1.3.5 iptables src... Thank you in advance for your time, Scott Wahlstrom System Administrator scottwahlstrom.org
