A slight problem with that is that not all parts of /proc/sys get renamed this way: snapcount:/proc/sys/net/ipv4/conf# ifconfig lo down snapcount:/proc/sys/net/ipv4/conf# ip link set name lo0 lo snapcount:/proc/sys/net/ipv4/conf# ls -l total 0 dr-xr-xr-x 2 root root 0 Mar 29 13:16 all dr-xr-xr-x 2 root root 0 Mar 29 13:16 default dr-xr-xr-x 2 root root 0 Mar 29 13:16 eth0 dr-xr-xr-x 2 root root 0 Mar 29 13:16 lo Which can be very confusing. This problem exists in both 2.5 and 2.4.

That is what i usually do - set up /etc/mactab and run it very early at boot. Running it later is usually flakey. e.g. it can also give confusing effects with old style named ip aliases. -Andi ^ permalink raw reply [flat|nested] 2+ messages in thread
