Dear Group, I am getting the following whenever I tried to do any operation with iptables. % iptables -L iptables v1.2.7a: can't initialize iptables table `filter': iptables who? (do you need to insmod?) Perhaps iptables or your kernel needs to be upgraded. % rpm -qa | grep kernel kernel-pcmcia-cs-3.1.31-13 kernel-2.4.20-28.9 kernel-BOOT-2.4.20-28.9 kernel-doc-2.4.20-28.9 kernel-source-2.4.20-28.9 % lsmod Module Size Used by Not tainted e1000 54528 1 ext3 61280 2 jbd 46804 2 [ext3] 3w-xxxx 36192 3 sd_mod 11916 6 scsi_mod 63416 2 [3w-xxxx sd_mod] How do I get this resolved? It seems the problem is after I upgraded the kernel. I am running RH 9. Thanks, Prince.
