IP-Aliasing:
============
o For IP aliasing you must have IP_ALIAS support included by static
linking.
o Alias creation.
Alias creation is done by 'magic' iface naming: eg. to create a
200.1.1.1 alias for eth0 ...
# ifconfig eth0:0 200.1.1.1 etc,etc....
~~ -> request alias #0 creation (if not yet exists) for eth0
and routing stuff also ...
# route add -host 200.1.1.1 dev eth0:0 (if same IP network as
main device)
# route add -net 200.1.1.0 dev eth0:0 (if completely new network wanted
for eth0:0)
o Alias deletion.
Also done by shutting the interface down:
# ifconfig eth0:0 down
~~~~~~~~~~ -> will delete alias
Alias (re-)configuring
Aliases are not real devices, but programs` should be able to configure and
refer to them as usual (ifconfig, route, etc).
Relationship with main device
-----------------------------
- the main device is an alias itself like additional aliases and can
be shut down without deleting other aliases.
