Do the Fedora network init scripts support additional secondary IP

addresses exist that works like IPV6ADDR_SECONDARIES?
I just skimmed /usr/share/doc/initscripts-*/sysconfig.txt, but I
didn't see anything to that effect, so I'm guessing the answer is no,
and I have to use aliases and 'ifcfg-eth?:0' files.
Yes, at least for IPv4. There is absolutely no support from the GUI, but
you
can manually install /etc/sysconfig/network-scripts/ifcfg-ethX:Y. For
example, I have an ifcfg-eth1 and an ifcfg-eth1:1, with a second IP
address.
Just copy ifcfg-ethX to ifcfg-ethX:1, and stick in an additional IP
address.
That's exactly what I'm trying to avoid--I don't want Fedora to add
the 'eth0:0', 'eth0:1', etc. labels. I'm wondering if the init
scripts support multiple addresses WITHOUT aliases.
I've never been able to find a solution to that that didn't require running
another script. /etc/rc.local is a kind of "catch all". There are also
/etc/sysconfig/network-scripts/ifup-post and ifdown-post.
Using iproute2 certainly gives good control.
ip address add 10.20.30.40/8 dev eth0
ip address add 10.20.30.41/16 dev eth0
ip address add 10.20.30.42/24 dev eth0
ip address add 10.20.30.43/32 dev eth0
ip address add 192.168.1.1/24 dev eth0
is an example of how to add addresses to an interface.
You may also use the same command to setup routes for your new found
diversity of addresses :)
I'm familiar with the manual method. What I'm wondering, now, is
whether the init scripts support any method that achieve the same
effect.
Forget what I said about ifup-post and ifdown-post. That was a brain
fart. I think there used to be ifup-local and ifdown-local but they no
longer seem to be called. You could hack that into it, but from my
point of view I'm trying to learn how to drink the fedora kool-aid.
Looks like you are too. Sorry I couldn't be of more help.
