Static IP configuration gives "default gateway IP address is invalid" error

[David Faure]

Binary package hint: kde-systemsettings

Just after installing kubuntu gutsy, I tried to configure networking. In systemsettings, Network Settings, Network Connections, admin mode, Configure Interface.
I set the following manual IP settings:
IP = 192.168.0.7
netmask = 255.255.255.0
broadcast = 192.168.0.255
gateway = 192.168.0.254
Clicked OK, and then Apply in the systemsettings module --> the error "The default Gateway IP address is invalid" error appears.
I don't see why - it's my gateway address and it's within the subnet, so it's definitely valid.
And when closing systemsettings all the changes are lost!!

I did the same configuration manually in /etc/network/interfaces and things are working okay now, so this is obviously a bug in the GUI.

I am unable to reproduce this in Hardy. Please view the following attachment for proof. I even tried your same exact settings without any problems as well. Are you able to still reproduce this problem?

Bah, I just now realized who filed this bug :) Have you given this a shot in Hardy at all David?

Hi nixternal :) Small world.

I haven't tried Hardy at all, I admit that I lack time to test alpha releases of kubuntu. I'll try to remember to try this again when I upgrade.

Probably not a bug in systemsettings itself but rather in knetworkconf.
Though knetworkconf is pretty much busted in KDE4 so it's hard to tell if this is still valid.

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue for you. Can you try with the latest Ubuntu release? Thanks in advance.

See my previous comment.

Since it's totally busted and seemingly unmaintained upstream, we are removing knetworkconf from distribution.
