Dear David, Thanks for the advice. Seeing as I have never manually done a kernel install, I have just taken the following steps:- -upgraded to iptables 1.2.8 from tar.gz -installed kernel 2.4.22-1.2115.nptl using "no-brain" rpm commands. Those purists amongst the list readers will be happy to note this has not got me anywhere:- ******************************************************************* iptables -L /lib/modules/2.4.22-1.2115.nptl/kernel/net/ipv4/netfilter/ip_tables.o: init_module: Device or resource busy Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters. You may find more information in syslog or the output from dmesg /lib/modules/2.4.22-1.2115.nptl/kernel/net/ipv4/netfilter/ip_tables.o: insmod /lib/modules/2.4.22-1.2115.nptl/kernel/net/ipv4/netfilter/ip_tables.o failed /lib/modules/2.4.22-1.2115.nptl/kernel/net/ipv4/netfilter/ip_tables.o: insmod ip_tables failed iptables v1.2.8: can't initialize iptables table `filter': iptables who? (do you need to insmod?) Perhaps iptables or your kernel needs to be upgraded. ********************************************************************* At this stage, am I going to have to manually configure the kernel ?? I guess so, but seeing as I do not know what I am doing, I'd appreciate any input from somebody who knows what they are doing. steve On Mon, 2003-11-10 at 20:04, David C.
