Network manager doesn't work in opensuse 12.1 for wired connection

I’ve set up opensuse 12.1 twice yesterday. Both the times, i had the same problem.

When i start with live usb, network manager works fine and i can configure my wired connction.
But after installing, Network manager icon disappears from panel. From application, i can open ‘network manager’ again but only vpn is shown available to configure. But Other options eg. wired, wireless are disabled there(faded up) :frowning: .

Please discuss to solve this problem.

Thanks :slight_smile:

Thanks. I’m using kde. I’m going to follow the page mentioned

  1. Don’t know if it should be considered a bug, but it’ts well known that the NM applet in the tray isn’t enabled by default. Enable by launching NM from the menu or KDE launch, then click “Properties” and check the appropriate checkbox.

  2. Sounds to me you haven’t configured your NIC in YAST, depending on exactly what method you used to install you may even have multiple interfaces configured for the same NIC (only one will work).

Actually i’ve to enable network manager. Because i’ve to change the default mac address to get connected to the internet.

In yast i’ve got no option to change default mac id.

I managed to appear networkmanager icon in task panel by adding widget. But it shows ‘red cross’ notifying network manager is not running.

There is an active option in network manager to clone mac address when it is used in live usb. In Yast i haven’t got it. By the way, kwallet is configured. I don’t know kwallet have any interference in network manager.

After reading that article, I’ve managed to appear networkmanager icon in task panel by adding widget. But it shows ‘red cross’ notifying network manager is not running.

I’ve to change mac address to get connected to internet. In yast, i haven’t got option to change it.

Can anyone have any idea to get connected to internet?

I’ve to reboot each time to post here from windows

Please post the output of :

ls -l /etc/sysconfig/network/ifcfg*

Make sure You’ve got controlled by Network Manager checkbox enabled in YaST and don’t change anything else there.

That usually means that your system is setup to use “ifup” settings (configurable with Yast). I think that’s the default if your system does not look like a laptop to the installer.

I suggest you go into Yast network settings, and see if you can switch to using NetworkManager.

Experience with 12.1 shows that after such a switch, you might need to reboot, or at least to run


/etc/init.d/network restart

to get it working properly.

Thanks everyone…

My system is setup to use “ifup” settings (configurable with Yast) (as i’m using it in desktop)

I’ve changed it… to user controlled with network manager…

Everything is done smoothly.

As i’m very new to opensuse, i didn’t know it.

Thank you all very much…

We’re really glad to hear it works :slight_smile: Thanks for the feedback.

Best regards,
Greg

Last issue,

If you’re trying to modify (spoof) the MAC address, assuming you’re running KDE I’ve already submitted a bug that this doesn’t work in any NM up to 12.1, in fact the clone setting you refer to appears starting in 12.1 but still doesn’t work.

I’ve posted the workaround elsewhere including my bug report that works, if you can’t find it I can repost here. Involves disabling the network connection, running the proper ifconfig command, then re-enabling the connection.

I’m using this old fix in /etc/init.d/boot.local never had any issues with it.

/sbin/ifconfig eth0 down
/sbin/ifconfig eth0 hw ether xx:xx:xx:xx:xx:xx
/sbin/ifconfig eth0 up 

Always wondered why it’s not implemented into yast network configuration.
I think knetworkmanager has this option working, seen it on fedora kde.

Hello, I had this problem, I think there is a conflict with the management of pop-ups and permissions.

I can think of two options:

  1. Run as root: nm-connection-editor with which you can modify and save the settings.

  2. Modify the permissions to / etc/dbus-1/system.d/NetworkManager.conf and give all rights to our user Network Manager.

Neither seem right but I work, I found no real solution to this problem that I found even read that it does not happen in 12.2 RC1.

;D bye.

Hello all posting to this thread, i’m desperately trying to connect to the internet with Suse OS tried 12.1 64 bit and now trying 11.4 64 bit, i’ve mobile broadband from ‘three’ and in both of these distros, NetworkManager is not working, have tried all of the advice here but unlike you nipu 011 still no luck!

Greg,
I checked network controlled by networkmanager in Yast and ran

ls -l /etc/sysconfig/network/ifcfg*
-rw------- 1 root root 172 Feb 18 2011 /etc/sysconfig/network/ifcfg-lo
-rw-r–r-- 1 root root 28066 Feb 18 2011 /etc/sysconfig/network/ifcfg.template

Wise Penguin,

I did restart newtworkmanager after switching and got

Shutting down the NetworkManager done
Shutting down the network interfaces:
eth0
no configuration found for eth0
nevertheless the interfacewill be shut down.
eth0 done
Shutting down service network . . . . . . . . . done
Starting the NetworkManager done
Connecting… 1s
waiting

and then went back to command prompt!?

Any help please! have been working on this for too many days!

I think that message only indicates that there is no “ifcfg-eth0” file. If you are using NetworkManager, then that is expected and should not be a problem.

The wired interface should be working, without you having to do anything. If it is not, then look for logs that might indicate what is going wrong. I guess “/var/log/NetworkManager” should be the first place to look.

Many thanks for your reply nrickert, apologies for only just seeing it, kept checking my e mail to see if i’d had replies and there was nothing, should have been checking here instead!
From looking at forums seems like folks are encountering a lot of difficulties with huawei mobile broadband devices in SUSE, Looks like Network manager is problematic if using KDE desktop!? I see you are using 12.2 do you have any idea if problems with Network manager have been resolved in 12.2, should i just try it? will take a look at “/var/log/NetworkManager” and get back to you, in the meantime here’s another thread i replied to with some maybe helpful info

many thanks for your time

I recently reviewed NetworkManager for 12.2 on my blog:
NetworkManager in opensuse 12.2 – a review

Here’s the brief summary. An update for NetworkManager came through about 2 weeks ago. After applying that update, NetworkManager works great. (Before applying the update, it had some of the same problems that you saw in 12.1).

Thanks nrickert, read your blog and think i’ll try 12.2 again, /var/log/NetworkManager didn’t reveal anything all i got was ‘permission denied’ was logged in as root so…what am i doing wrong? am well fed up of trying to get this mobile broadband device and network manager to work, such a shame, would love to be using suse instead of windows :\

I have no experience with a mobile broadband device. My experience is limited to wired and WiFi. Sorry.

No worries, thanks for help anyway
