I am occuring a problem with my ethernet connection. Two days ago everything was fine. Yesterday when I turned on my computer I had no internet connection, so I “played” a little bit with the modem and restarted few time the computer. During one of the restarts I couldn’t login any more (no space available problem), solved it however there was no ethernet connection. Furthermore some of my configurations got lost (default app for file extension, all items at the panel etc) I tested the modem/connection via vista/ubuntu and everything worked so I narrowed down the problem to my instance of the opensuse 11.2. I searched a little bit on the forum and after typing “rcnetwork restart” I am having this output:

As far as I checked the /var/log/messages file. The problem is I think in the fact that eth0 can not get the IP from modem. Cause when I checked logs from 2days ago when eth0 was leasing for the IP it was getting it. Also I can’t ping the gateway.
Anyone has an idea how I can solve this problem. Will greatly appreciate the help.
Check your fiewall settings under yast. Mine is set to External Zone for my net card.
You can also stop and start the firewall to see if thats what is stopping you from getting on the net.

Mine is also set to external zone, also when I’ve stopped the firewall I still couldn’t connect (tested via ping, waited 3min to get IP, which I haven’t receive). Besides I have never changed any firewall settings.
According to your logs, for some reason your ethernet (hardwired) interface is managed by ifplugd. For some reason somewhere between when ifplugd starts managing your eth0 interface and when your dhcpcd starts running something failed.
Recommend you take a look at the various ifplugd commands, try them to analyze what might have gone wrong (eg are you physically plugged in, is the ethernet port light on?).

The light is on when the cabel is physically plugged in. Can you recommend me some ifplugd cmds to use. Since I don’t know this cmd I don’t know what is important or what will be helpfull to solve the problem. What I was able to determin is that ifplugd detects when the cable is pluged in/out.
Scratch what I said for the moment, it might be possible to find the YAST setting that controls ifplugd.
Are you using IFUP/IFDOWN and not NetworkManager? If so, try take a look at the YAST network card settings > Edit> General tab.
Verify that the “Activate device” dropdown is set either to Boot Time or to On Connection. I’m taking a look at my OpenSuSE 11.3 which for some reason uses the HotPlug daemon instead of the ifplugd daemon and I don’t have an 11.2 setup to know if this is just a recent change across versions or the “On Connection” option is configured for ifplugd… If someone else can clarify this point, that’d be good.
In any case, save the setting and reboot (particularly if you’re set to “Boot Time”).
Hopefully that will fix your problem.
If that doesn’t work, then maybe go back into the setting and set to “On Connection,” save and see if things work immediately (give it about 3 minutes maybe to reset the network device and acquire settings). If that doesn’t work, then set back to Boot time, reboot and check… and if it STILL doesn’t work then post back.
Originaly I was using “On Cable connection” I have changed that to “On Boot” (rebooted) didn’t work changed again to “On Connection” didn’t work (not so big supprise ). I have verified that the modem is actually giving me the IP adress (logged in to the modem, checked IP adresses given), don’t know if that is some kind of a clue. Also I am getting this “error” constantly
eth0: 43 has zero length
eth0: failed to parse packet
Howdy,
Pls post ifconfig to verify for sure whether you’re assigned an IP address on the eth0 interface, whether there are any other interfaces (besides I see your wlan which is not connected), and if your modem says it issued a lease whether the date is today.
So, for instance awhile back I deployed OpenSuSE on a virtual machine and every time it was moved from from one network to another and back again, for whatever reason it wasn’t able to use an existing ethernet interface and kept creating new interfaces, incrementing (eg eth1, eth2). And, of course each time I would then have to modify the network settings to use the new interface, or manually remove the extra interfaces to start from eth0 again.
if your modem says it issued a lease whether the date is today.
I also checked just out of curiosity the wlan0, the same problem. As I checked “logs” on the modem it looks fine (time, date etc), “from modem point of view” everything looks fine. The IP adress was given both to ethernet and wlan. However the computer “don’t have” them.
ifconfig -a //output when ethenrnet cable is plugged in and modem states that eth has IP
Without actually addressing whatever is causing your problem, most people are advised that whenever you have a wireless interface they recommend using NetworkManager instead of IFUP/IFDOWN (which I see you seem to be doing).
YAST > Network Devices > Click on “Global Options”
On that tab, you should be presented with several options, the first is “User Controlled with NetworkManager”
Although may not be necessary, I recommend rebooting afterwards.
You should then be able to invoke Network Manager either from a tray icon (lower right on the bottom Panel) or from the “Run Command” typing networkmanager or knetworkmanager.
Once Network Manager is launched, you can then go in and start configuring your wired and possibly your wireless connections if your settings aren’t already inherited.
Just curious what you’re using currently for your WiFi configuration…
Also, am curious if you have both your wired and wireless network adapters enabled at the same time… If they’re both enabled and connecting to the same Internet Gateway, I can sure imagine some weird routing issues and who knows what else… If this is what’s happening, just disable one of your network connections and the other ought to work (Probably require a reboot if /sbin/network restart doesn’t work).

No I never use them both at the same time :), wlan is for university eth is for home. Once eth is on wlan is “turned off”.

As I checked in the Yast I am using ifup for network managing (i think both eth and wlan)
I am going to test the NetworkManager, however I have to install it first and then the dependency hell starts (no internet = no easy installation). I think it’s gonna take me a while to collect all the pkgs needed for the installation. After I’m done with it and tested it I’m gonna tell you the result hopefully it will work
Oh question do you have a live CD around if so boot the computer with the live CD and see if you get a connection. If I rember right the live CD’s use the Network Manager as the default. You als might be able to get the setup and copy it to your computer so you can edit yours and make it the same to get your net card working.
Installing NetworkManager is only a general recommendation supported by just about everybody if it’s not a problem so I’m not suggesting trying too hard to install… But, I still am curious what you’re using for your wireless network management… Surely you’re not doing it by CLI using wpa_supplicant and iw, right?
If you’ve tried all steps I’ve recommended to this point and still don’t have connectivity, then I do support please_try_again’s suggestion to test making a dhcpcd request.
The other thing I would highly recommend is to test configuring a static IP address(Configure using YAST or NetworkManager if you succeed in installing), using an <unused> valid IP address for your network, you haven’t yet posted anything I’ve seen that states what your NetworkID is, you say you have access to your DHCP server so you should be able to gather the info you need…
GW - For home networks, usually 192.168.0.1 or 192.168.1.1.
Mask - Typically, if your gateway address is one of the above, it will be 255.255.255.0 or will be an address followed by a “/24”
IPaddress- If both the above is true, then any unused number will suffice, if you don’t understand what I mean unless you’re very, very unlucky 192.168.0.241 should be unused and valid on your network (if your GW is 192.168.0.1)
DNS - Typically, on home networks the GW is also your DNS.
I recommend configuring that for your wired (not wireless) connection for simplicity.
Configuring with a static address will test and verify whether your network card is functioning and will further suggest your problem is related to only DHCP.
But, I still am curious what you’re using for your wireless network management… Surely you’re not doing it by CLI using wpa_supplicant and iw, right?
I think for wlan I’m also using ifup, cause in the Yast the “network setup method” is set to ifup.

I’m going to install the NetworkManager now and try conf it. Also if that fails I’ll paste the “logs” from the modem (DHCP server).
If you use the ifup method, I would replace the line in red with:
STARTMODE=‘auto’
Didn’t work.
However I have installed NetworkManager and it worked :). Now the only “problem” is that I don’t know how to conf wlan. Eth0 works fine however I have to use wlan on my university.

There is no icon of the NM in the panel (I’m using xfce) nor there is a cmd k/networkmanager. The ver I have installed is NetworkManager-0.7.1_git20090811-4.2.i586 (from opensuse pkg search). I’ll try to figure that out on my own, cause I can see that there are some tutorials. However If I will get stuck I will post here in order not to start another thread.
You can place a icon of Network Manager in the system tray, it should be under the pref’s and when you dont have your wired connection pluged in it should switch to wlan.
