Hello!
Anyone who knows how I setup my NetworkManager to use the correct host name on my system, if that is possible. NetworkManager ignores the specified hostname and uses ‘localhost’, which is a bit annoying.
Cheers
Anyone who could give me a hint? I have a physical conncetion to a lan NFS network which is defined by DNS names. After I started using a mobile broadband, which I occasionally do, localhost has a different name and I can not enter the NFS server.
I can change back to ifup, reset router and reboot but it would be better if I could manage to have NetworkManager using the ‘correct’ hostname.
I am not knowledgeable with network settings so if I obviously does something strange just point it out please.

If you really are using mobile broadband, then more than your host name changed.
To confirm this, please post the output of /sbin/ifconfig for both types of
connections. In addition, please post the output of the command ‘df’ when you
have access to the NFS volumes.
If you change the wired connection to be “Started automatically on cable
connection”, then you will be able to switch between the two types merely by
plugging in the wired cable.
BTW, you may be connected to some NFS volumes, but it is not described as an NFS
LAN.
I managed to set hostname and domain in Yast. The system ignored the domain name that I set, but used the hostname.
I fixed the domain name problem by adding a line to “/etc/dhclient.conf”.
Perhaps you can do something similar.

Does this give some valuable info ?

Note that the IP number for the eth0 is 10.0.0.1, which is internal to your
network, while the broadband connection resolves to an address at
telenormobil.no. The only that broadband connection can address anything on your
private network will be over the Internet and back through the router attached
to the private network. Most small routers will let you direct a specific UDP or
TCPIP port to an internal address. I do this for an SVN server that holds files
for a project that I share with 2 other people. This mechanism would be rather
slow for any serious NFS file sharing.
No.
Thank you lwfinger!
I managed to access the server with the NW settings controlled with (K)NetworkManager, I changed ‘host_allowed’ on server from DNS to IP. But I can no longer have ifup configured to access server. I suspect that it has something to do with hostnames as I see ‘localhost’ has the first internal IP address while the defined hostname has the second. This was probably(?) altered when I changed the settings to NetworkManager the first time.
I prefer not to use NetworkManager as I can not have several connections available simultaneously, and usually I am connected to the internet through the router.
Do you know if there could be any inconsistencies if I manually edit the entries under Yast > Networkservices > Hostnames? Maybe I can solve something with changing the aliases?
I really would like to get rid of all these entries and have NetworkManager, when I need to use it, use the same hostname as I defined the system to use during installation.

The hostname changes at boot time such as that I am logged in as olav on localhost not as olav on DDAmt which it should be, and the connection name in the router changes accordingly (if connected).
