nm-connection-editor does not work correctly when you have multiple wired connection profiles with different MAC addresses set (and only one lan card)

[lokster]

Binary package hint: network-manager-gnome

I have two network adapters - eth0 and wlan0.
In nm-connection-editor I have two wired connection profiles:
 auto eth0 - connect automatically, system setting, MAC addres 00:19:DB:3B:92:0C (this is the real MAC addres of the lan card), DHCP

 home eth0 - connect automatically, MAC address 00:11:2F:74:31:68 (this MAC address is fake), Method - manual (static IP)

The problem is that "home eth0" does not show up in the pop-up menu when I click on the network icon in the notification area.
And when I set the MAC addres of "auto eth0" to 00:11:2F:74:31:68 (the same as "home eth0") it also does not show up in the pop-up menu. Instead there is a connection named "Auto Ethernet".

This happens on Ubuntu intrepid, the package is network-manager-gnome version 0.7~~svn20080817t183748-0ubuntu1

why is this wrong with that? for me that looks expected. specifying a mac address will lock that connection to that device ... which implicitly means you have no choice anymore. And when you specify wrong MAC address everywhere its just the "auto ethernet" connection which NM creates when there is no matching connection configured.

@Alexander Sack, but that way I am not able to use 2 different MAC addresses on 2 different networks, with only one lan card, because when I set the mac address, the profile does not show in the network manager pop-up menu.

And worse - even when I have only one wired connection profile (for example "auto eth0"), when I set the MAC address in its settings, this profile disappears from the network manager pop-up menu, and "Auto Ethernet" appears (but it is NOT selected).

So tell me, if this is perfectly normal, how am I supposed to change my MAC address, and why is this setting if I can't change it? WITHOUT using Terminal on every single reboot. Actually, without using Terminal at all.

I fully agree, this supposed function is still completely broken. If Ubuntu wants to tout itself as a OS that can seamlessly switch between networks then something this simple should just work.

How can go about fixing this?
