Guessnet hangs on attempting to run with ifupdown mode

[Andrew]

Binary package hint: guessnet

Guessnet used to work on my laptop, but is now hanging.

I execute:
sudo guessnet-ifupdown --debug

The output is:
guessnet: program name is guessnet-ifupdown: enabling ifupdown mode

Then it sits there with no response. CTRL+C successfully aborts the program

Hi,

I have the same hardware as you (also a D630). I can confirm what you have. Running Karmic. I do however have a working network setup. And I never call guessnet directly.

But my interfaces file looks different, see https://help.ubuntu.com/community/NetworkConfigurationCommandLine/Automatic#Configure%20multiple%20locations for what I have (the page is WIP) but that part is fully done.

What happens when you ifup/ifdown your interfaces? Do you see any relevant information?

Could be that this is related to https://bugs.launchpad.net/ubuntu/+source/guessnet/+bug/433677

I guess you both haven't read the documentation. In ifupdown mode, guessnet expects /etc/network/interfaces to be fed on its stdin. That's why you think it hangs — as you haven't supplied any input to it.

In other words, it seems to be not a bug.
