Due to strong 1.3.42 route.c changes it is difficult to maintain my
current ip_alias implementation with its device EMULATION.
This moved me to start a completely new development (v0.4) with these criteria:
- create REAL-real devices, so kernel 'tasks' can use them (specially
routing)
- maintain ioctl interface managing (ifconf) same as v0.3 (magic naming)
so you dont have to unpatched ifconfig, netstat, etc .. can be used.
- hashed lookup.
- AF_ independent (not IP specific)
I renamed ip_alias to net_alias due to it IP-independent features.
Alan Cox agreed to merge my new development (when done :) to linux dist.
By now, I'm alpha testing it. It is succesfully running over 1.3.45.
# cd /usr/src
# zcat <patch_file> | patch -p0
# make config (answer 'y' to "IP: NET-alias support" )
# make dep
# make zImage
and lilo the new kernel ...
after boot:
# ifconfig eth0:0 <new-ipaddr>
~~ magic naming: eth0 alias #0 (up to 256/iface)
# route add -host <new-ipaddr> if it is a same-network-as-eth0 alias
or
# route add -net <net-netaddr> if it is a diff-net alias
If anyone wants to try, just ftp to the address below.
BEWARE that it is not finished yet.
You can ftp 1.3.45 patch from
ftp://200.9.147.228/pub/linux/net_alias
Of course there are still (stable) ip_alias v0.3 patches for 1.2.13,
1.3.32 & 1.3.40 at (also README*):
ftp://200.9.147.228/pub/linux/ip_alias
Any suggestions/problems/flames please e-mail me.
Thanks for your TTTT (*).
Cheers....
