Hi,
As far as I understand the network settings in Yast is unable to change host- names, domain servers etc. when network manager is running. This is clearly indicated by the warning dialog that pops up any time one tries to use network-settings module in Yast, while using the network manager.
It is (able to change hostnames). Just close the warning dialog and switch to hostname/DNS tab of network configuration. There you can set any hostname you want :) I've blogged on it few months back: http://hedgehogpainter.livejournal.com/3916.html Some background info on this: we (yast2-network maintainers) had been asked to put the warning pop-up in and to disable any network configuration by YaST once NetworkManager is in charge of controlling the network. It was only later it's been found out that some bits and pieces can be still configured via YaST only as no adequate replacement for them has been implemented in NetworkManager, hostname being the most prominent example of those ... It was thus easier to enable some configuration in YaST again (while keeping the initial warning) than to trying to implement it in NM so late in the release phase
So one understands that all this (setting hostnames, etc.) can be set from network- manager. However, the default (wired) connection in the gnome-network-manger applet is locked and allows the changing of none of these values.
Afair, it (setting hostnames) was supposed to be implemented for 11.2 (as it was too late for 11.1). I tried to do some bugzilla digging around and all roads lead to Rome .. erm all duplicate link to this bug: https://bugzilla.novell.com/show_bug.cgi?id=440809 which is closed as fixed I But otherwise, no clue. I don't hack on NM ... hB. -- \\\\\ Katarina Machalkova \\\\\\\__o YaST developer __\\\\\\\'/_ & hedgehog painter
