Support for IP aliases
Last modified: 2008-11-14 01:57:59 EST
I'm using the F10 PR KDE spin.
NetworkManager doesn't support IP aliases (eg, eth0:0) where multiple IPs can be assigned to the same NIC/MAC address.
Aliasing is deprecated in general. You can add multiple IP addresses to the _same_ device using /sbin/ip manually, or by adding multiple addresses in the NetworkManager connection editor in the IPv4 pane. You don't need to use aliases at all.
Assigning multiple addresses or aliasing gives same effect. However, how to have all the IPs assigned to a NIC active at the same time? I don't see how that can be done in Network Manager (one dhcp, one static or both static or both dhcp, etc).
