I use the kernel 2.4.3 which had been compiled by Mandrake. I don't know if these options have been selectd. Because There is iproute2 in Mandrake 8.0, I think these have been done. I can run this command in Redhat 7.1 whose kernel version is 2.4.2. >On Thu, Jun 07, 2001 at 08:35:47PM +0800, javaman wrote: >> hi, >> >> I run ip rule list on Mandrake 8.0, and get >> >> #ip rule list >> RTNETLINK answers: Invalid argument >> Dump terminated > > Did you select 'IP: advanced router' and 'IP: policy routing' >in your kernel configuration. >
