It is certainly possible to run ipchains with 2.4.x kernels, but you'll need to ensure that it support for it is enabled within the kernel. This may require a re-compile of your current kernel. The "modern" version is iptables and operates in a similar fashion to ipchains. Again, you'll need to make sure that your kernel has support for iptables enabled (whether it be as a module, in which case just try "modprobe ip_tables", or statically compiled into the kernel itself).

Up until now, because of the small, infrequent, amount of time I am actually connected to the internet, I have simply been ensuring that I always log on as a normal user (rather than root) to protect my PC, however I have recently been wondering whether it would be wise to install some kind of protection for my PC. Looking in my little Linux text book it would appear that "ipchains" would probably be sufficient for my needs (rather than setting up a dedicated firewall), however, when I try to use ipchains I get the error message: ipchains: Incompatible with this kernel. The kernel I am using is 2.4.10 and I am wondering if this error message is hinting that ipchains has now been superseded. Is there a modern replacement for ipchains? If so then what is it and where could I find some info on setting it up to protect my PC? Thanks, Ian. _______________________________________________ main@lists.alug.org.uk http://www.anglian.lug.org.uk/ http://lists.alug.org.uk/mailman/listinfo/main Unsubscribe?
