Greetings The ip route how-to describes the following for setting up source routing #echo 501 uras.out >> /etc/iproute2/rt_table #ip rule add from 10.0.0.0/24 table uras.out The first line complains of a missing directory, which is simple fixed (create dir iproute2 in etc) The second line then reports Error: argument "uras.out" is wrong: invalid table ID The op sys is RH 7. I had exactly the same problem with 6.2 and was hoping 7 would solve, but did not. Any ideas? Regards Warren ps The specs on iproute2 look great. Thanks to all those who contributed. I just wish I could get it working.
