[Bug 94068] Can't configure IP addr's on multiple NICs

[swainstm]

You have been subscribed to a public bug:

Firstly let me say that I have reported this as Bug #94062, but I think
I put it in the wrong place, so have recreated here. Apologies for any
confusion.

I don't seem to be able to use the "Network" GUI application to
configure addressing on multiple ethernet NICs (in my case 3 interfaces)
in Feisty Desktop 64 bit Herd 5.

Although I can configure multiple IP addresses on each of the NICs, it
appears that each of the IP addresses is only active on 1 interface at a
time, as shown in ifconfig, netstat -nr and access to the box. ifconfig
shows all the interfaces active, but only 1 has an IP address. It
appears, I can change between the interfaces that have the active
address, by clicking on the "Network" icon in the right hand side of the
task bar and selecting different interfaces on the radio button,
however, I want all interfaces address and their corresponding IP
address to be active at the same time.

There is no way I can fix this from the GUI. I can fix by doing a
"ifdown" and "ifup" on each of the interfaces. However, if I reboot, I
am back to square 1.

I have tested this on 3 different machines with different ethernet
cards, and brand new installs with nothing else on them and it is always
the same. I have also tested in a VMWare environment to try and make
this as reproducible as possible, and I always get the same results. If
I try this with Herd 5 with no updates, I get slightly different
symptoms, but basically the same problems (see link to forum link bellow
for more details). With the latest updates, it is pretty much as
described above.

To reproduce :-
- may VMWare machine with 3 interfaces (or any machine with 3 interfaces)
- do basic Feisty 64bit Desktop Herd 5 install.
- from "Network" GUI under "System"/"Administration" configure static address on all 3 interfaces.
- check status with ifconfig. Note: I think when I did this with no updates from the basic Herd 5 install, at some point it stated working, but "Network" icon in the task bar was showing "disabled". After installing the the updates, this turned into the old problem where only 1 of the interfaces at a time could have an IP address. Nothing in the GUI I did could fix this. ifdown/up from the command line would fix this, until you rebooted.
