Bug 483468 – net-misc/networkmanager - nm does not set IP4_NUM_ADDRESSES in environment

• Product: Gentoo Linux
• Status: RESOLVED TEST-REQUEST

[Description Ryan Li 2013-09-03 09:31:43 UTC]

Hi,

I am writing a dispatch script for NetworkManager that sets a specific route when a network is up.

I looked at NetworkManager's man page and it says:

> The environment contains more information about the interface...
> IP4_NUM_ADDRESSES contains the number addresses the script may expect.

However, I put some debug lines in my dispatch script and here's the output:
> DEVICE_IP_IFACE=eth0
> CONNECTION_UUID=cd76e84d-****-****-****-7956e10a8291
> DEVICE_IFACE=eth0
> IP6_NUM_ADDRESSES=2
> CONNECTION_ID=Wired connection 1
> PWD=/
> IP4_NUM_ROUTES=0
> SHLVL=1
> IP6_ADDRESS_1=f47b:f301::****:****:0:0/64 87c:f301::****:****:0:0
> IP6_ADDRESS_0=c47b:f301::****:****:0:0/64 d87b:f301::****:****:0:0

IP4_NUM_ADDRESSES isn't set as an environment variable, and a couple seconds after the dispatch script is run, I could see interface eth0 assigned an IPv4 address. So I assume that the dispatch script is being run prematurely.

Reproducible: Always

Created attachment 357750 [details]
emerge --info networkmanager

does it work if you change the settings in NM to say "require ipv4 connectivity for this interface to work".

It's in nm-connection-editor, not the gnome-control-center network panel.

No it doesn't work. I get the same output.

What networkmanager version? Are you using ifnet or keyfile plugin?

$ equery list networkmanager
 * Searching for networkmanager ...
[IP-] [  ] net-misc/networkmanager-0.9.6.4:0

I am not using any plugins.

Try with 0.9.8.4, you are probably using ifnet if you haven't touched anything

Also try with 0.9.8.8 and post "emerge -Opv networkmanager" output
