Re: ipconfig eth0:1 down doesnt do what i think it would
well basically the eth0 ip is 10.0.0.1. the static ip is normally on ppp0
when connected to the isp. however i want the static ip available to the
local network even when the connection to the isp and hence ppp0 goes
down. this is already working find with ip-down or rc.local starting up
eth0:1 with the static ip.
/sbin/ifconfig -i eth0:1 188.8.131.52
/sbin/route add 184.108.40.206 dev eth0:1
however if i attempt to remove eth0:1 at any point in time later eth0 is
also removed. whether or not ppp0 is up or down.
should ifconfig eth0:1 down only remove eth0:1 and not eth0? if so i guess
the problem is most likely somehting to do with my kernel?
if there is another way round this id like to hear it. basically i want
the ip that is assigned by my isp to be available to my local network
wether or not my connection to the isp is up. this "works" as it is but i
want to only have the static ip sitting on the ppp0 interface and not also
available directly on the eth0 interface when the isp connection is up.
the forwarding to ppp0 works fine if eth0:1 is never added, but if it is
added when ppp0 goes down, i can never renmove it without also removing
eth0 which is my problem.
thanks for any help :)
all that busts well ends loosely.
