OpenSUSE :: KDE Hangs When NFS Connection Lost
Jun 16, 2010
I have a server which is located in the basement. The server exports a few directories which I mount on my desktop using NFS. From time to time, the connection gets lost. The server is also not always on. I can't change that part, so I worked out a script which notifies me when it's going down, and when it's back up again. It also mounts everything back. However, As soon as I loose the connection, my desktop seems to be gone. KDE doesn't work, but I can use a few applications like Konsole, google-chrome, firefox, stuff like that. But the plasma-desktop around it hangs. As soon as the connection gets back again, everything works. I have this issue only when my desktop is running while I loose the connection to the server. If it's down when I start my desktop, everything works properly. Unless the server comes alive, the nfs directories are mounted and the connection is lost again.

I have freshly installed OpenSUSE 11.3 64 bit and reimported my old openvpn connections via Network Manager. Connection can be established fine, but after 3 to 6 seconds (pings) it will stop to receive any packets on the tun device.
I tried disabling the firewall, starting openvpn manually, no avail. I checked the message log and the openvpn output, no messages recorded.

I played with the Network Settings section in YaST, because I wanted to use the wireless network card I installed into the PCI port. OpenSUSE recognised the type of card and its MAC number, and told me that I needed to install a firmware (fwcutter something). I tried some changes on the cable internet connection (like activate on plugged) while I tried to change the wireless connection (like activate on boot).
What I have now is that my cable internet connection is not working at all (it was working just 3 days ago), my wireless internet connection is, as always, not working either. I managed to work the wireless card on Windows XP by finding its drivers.
Since the problem is with my office computer, I cannot answer the exact brand names of the ethernet card and wireless card. Shall I reinstall OpenSUSE 11.3 from the DVD I have?
Second problem: OpenSUSE does not recognise my external harddisk, it gives an error about mounting the device.

After having updated unconditionally all packages in Kde-desktop-factory-repository to get the latest version 4.4.4, I can no longer connect to the Internet through Knetworkmanager. I receive the the following message from a pop-up window when clicking on the Knetworkmanager icon
Code: KNetworkManager cannot start because the installation is misconfigured.System DBUS policy does not allow it to provide user settings; contact your system administrator or distribution.KNetworkManager will not start automatically in future.I tried opening Knetworkmanager in a terminal as root user through 'su' but received the following message:
Code:# knetworkmanager knetworkmanager(2331): KUniqueApplication: Cannot find the D-Bus session server:"Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken."

I was using yum to update a server, then my putty session to the server dropped.
I reconnected, and now when i try to do a yum list updates, i get the following message:
Another app is currently holding the yum lock; waiting for it to exit...
The other application is: yum
Memory : 42 M RSS ( 53 MB VSZ)

State : Sleeping, pid: 21762
Does that mean its still installing the updates i asked it to, and i just need to wait for that to finish so i can see what updates are left? or am i really in a bad spot now?

The computer is a K9n6pgm2+ mainboard w/2gig of RAM and an AMD Phenom Triple Core. My Harddrives are /dev/sda=320gig and /dev/sdb=80gig. Resident on sda is Ubuntu 10.04 (fresh install) w/Windows XP installed at the final 40 gigs, installed after Ubuntu install and then used the 9.10 live CD to reinstall GRUB. On /dev/sdb is Ubuntu 9.10.I installed the fresh Lucid install 3 months ago when I purchased the 320 gig HDD to replace the failing 40 gig and it has run perfectly until yesterday. I presently have a 2Wire Modem located at 172.16.0.1 and I have a new Motorola in the mail but I presently cannot get Lucid to find my internet connection.
If I boot into XP everything is fine. i can go all over the net. If I boot into Karmic, all is well. I am typing this in Karmic so it is strictly a Lucid problem and I have tried all that I know to do and I really want my Lucid install back.

Log file viewer also can't provide much help. I'm also affected by this issue that has been gone on my PC for almost 2 months, now. I've been forced to re-install Ubuntu ( from 9.04 to 10.04 ) countless time. As other users mentioned in their thread, the problems occurred randomly. Sometimes right after start-up, sometimes after 10 min to an hour of PC usage and sometimes no freeze at all. But the symptoms seems similar though on different component of hardwares. Me, myself, my PC always started to display freezing symptoms after 2-3 days of any Ubuntu fresh installations. The only way to re-boot are through RSEIUB/O ( and luckily I've never failed to do so ). Its just maybe took countless time of Ctrl + Alt + Del, before I could enter Grub menu and after that Ubuntu. Seems like that BIOS doesn't recognize HDD ( where the Ubuntu situated ), but oddly it ( BIOS ) only rcognize the CD/DVD drive . Lately, to overcome this HDD problem, I tried to pull out the SATA cable connected to CD/DVD drive and left only the SATA cable to HDD. And guess what, I've never encounter this unrecognized HDD problem for the past 2 days. I suspected the cause off all this issues are maybe the AsRock G31M-VS2 mobo that I've just installed about 2 month ago. But certainly, this issue never back me off my love to Ubuntu. As long its Open Sources.

recently i have combined 2 machines into 1. after doing this, the ping to the new machine stops, for no apparent reason, and consequently all traffic to/from the machine also stops. when using the two machines individually this never happened.Lastly, if i restart the network, it kills everything (like the network just wont restart - it reaches the last interface and hangs), and if i reboot the machine, it seems to be fine for about 3-4hours.has anyone seen anything like this when connecting a large number of hosts to 1 gateway, using linux as the router?

I used to be able to connect to the net using my laptop {Ubuntu 9.10 on Compaq nx7400.}by means of wi-fi . I do not know what I have done but I lost the facility to connect to the net.I noticed the Network Manager disappeared from the notification area. I manged to put it back. It detects the signal from the router and after entering my password it displays Connection Established but I still cannot access the net and does not load any web pages. I have the same Ubuntu 9.10 Desk on a memory stick, when I use it on the laptop it works fine.
I enclose a screenshot of iwconfig.I did sudo lshw -C network and it shows DISABLED. How do I enable it ? Are there any other info that I should supply and what and how.

We had a power-out, which left my Ubuntu box off.
The modem & router is a friend's place, and it was rebooted. Both his boxes (Windows XP and 7) work fine.
but I can't get my box to hook back up. I've tried rebooting, unplugging cable to router from both ends (my box and router), rebooting his modem (Rogers' service) by turning off and on power supply for 3 minutes (as recommended by Rogers).
Once I got the Network-auto to show in the dropdown menu (I have a radio symbol on panel across top), but not again. I tried adding and editing a network connection (both wired and auto) but neither works, and if I boot unconnected they disappear.
The only thing I can get to show is a black box to the right on the desktop that has a red x and says Network Disconnected.
Me and friend are both frustrated as I don't want to interrupt his working use of internet to fix mine.
I have never understood how to connect to internet really, but it seemed to have solved itself in the past.
There is no password on the router, and we are not using wireless (which we never got to work).
The Rogers Modem is a "Motorola Surfboard" (Black).
The router is an Airlink 101 super-g wireless router.
My machine is a p4 motherboard with builtin ethernet socket on back.
My Ubuntu is I think Karmic 9.1

I am mounting a remote directory using sshfs, over VPN. If the VPN connection is lost, the directory obviously can't be read. But, when I try to "ls" in its parent directory, the command just stalls. No error messages, and ctrl-d, ctrl-c, ctrl-z don't do anything. The command I ran to mount the directory was:
Code:
sshfs -o workaround=rename bt@example.com:/dir1 /dir1

I'm running 10.10 and I uninstalled some files through synaptic and it also removed a lot of other packages which messed up my whole system. I lost the connection to the Internet and also the taskbar. I don't know how to re-install those lost packages because I have no net connection. How can I fix this? This is what I removed:
Completely removed the following packages:
apt-xapian-index
libboost-python-dev
python-xapian

Three months ago my daughter went off to college with a new computer. I zapped her old system and successfully installed Ubuntu 9.04 from a CD. Everything worked fine including all the peripherals and the wireless internet connection. I was able to download and update applications without a hitch. Great system and so much cleaner and quicker than Win XP on the old machine. Then the system was shut down and lay idle for three months.When I fired it up a couple of days ago, all seemed normal except I could no longer access the internet even though the wireless network icon showed four or five bars. I first discovered the problem when I tried to update though Update Manager and noticed that 22 identified files could not be fetched. Neither Firefox, Skype nor Goodgle Earth can connect.
The router is a Linksys WRT54G router that connects to the computer through a Linksys WUSB54G USB network adapter. The router serves three other non-Linux computers without a problem, including one using the same model network adapter.I don't have much experience with Ubuntu, but this is some of the information I have been able to generate.
I tried a few of the recommendations found in other sites, but nothing seems to do the job. I am perplexed because everything was great until I shut down the system for three months and then started it up again. I appreciate any assistance and would be happy to provide additional information as requested.

I running Ubuntu ver 9.04 I have 2 problems that I think are related. After finally making a network connection I updated Ubuntu, and after a reboot I lost my network connection again.I updated the following file nm-networkmanager-settings.conf and saved it. After another reboot I then lost my network connection icon and it also does not appear under System > Preferences. I tried to then update the same file and can not save it, I get "could not save file".I have tried sudoedit, sudo gedit, gksudo gedit and some others that I cna not remember now and all give me the same result

I was trying to sync my Tungsten E with Debian Squeeze and it would just hang as if there was no connection. Trying pilot-link -l resulted in a message saying that it was looking for a new usb connection (or something to that effect) and would never connect. jpilot is set to use "usb:".
I moved to my laptop, which has Ubuntu Lucid, installed jpilot and it synced just fine using "usb:". What is "usb:"? How do I troubleshoot it? It seems to me that is the problem with my debian install.

Has anyone else been having problems with their wireless network connections since the network manager updates? I have two different networks that I connect to and have in the past had no problems since figuring out what files were missing and had to be either created or corrected and copied into the correct locations. I have tried everything I know to get my secondary wireless connection working to no avail(currently connected through my neighbors unprotected network), from deleting the connection, rebooting and recreating it, editing the files and copying them back into the correct locations and nothing works.
I have even had many crashes while using network manager. Using system-network-config eliminated the crashes but still does not allow the connection to connect. It attempts to connect and just hangs on waiting for authentication after prompting for the WEP key and clicking OK. What in the heck is going on since the devs created all these updates and have once again broken the most important aspect of any usable system, the network? I'm running F14 and KDE 4.6.1.

When I make a vpn connection to an openvpn server, I loose the internet connection.
The VPN works all right.
Server config (extract)
Client config
Client route without the VPN connection
client route with VPN connected (internet lost)
Is there anything I can do to the push rule of the servers's config file?

I am running ubuntu 9.1 on a Dell Dimension 2400. After installing ubuntu on the pc, it was automatically recognizing my router and connecting to the internet fine via ethernet. Then, my roommate unplugged the router and it won't recognize it. I can't access my router settings, and ubuntu is recognizing it as "inactive" but every other computer in the apartment runs fine. My PC uses a broadcom ethernet controller, and my router is a Linksys wireless N.

My ISP pushes software updates occasionally to my router. This also forces the router to restart. When the router restarts, my ubuntu box loses its network connection and does not automatically restore it after the router comes back online.How can I configure ubuntu to restore the connection once it is available again? It happens on my windows workstation...I am using ubuntu on a box with no screen / keyboard / mouse it serves as a fileserver and I remote desktop in. Obviously if the box drops the connection it is a major annoyance. I am using version 9.10

So, when I booted up, the wired connection was automatically detected and in use. Whenever I suspend my computer and then resume it later I lose the wired connection. It is detected (seen) by Networkmanager, but I can never connect. I found a way to restore the connection, but it is manual and I was wondering if I could automate this process every time I resume. Details follow:
Laptop: HP dm1z, Natty 64bit. ethernet card:
Code:
#lspci|grep Ethernet
03:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8101E/RTL8102E PCI Express Fast Ethernet controller (rev 02)
Likely culprit (according to dmesg)

I was running 8.04 and my internet (Comcast) comes via a Motorola SB5100 cable modem then into a Netgear router then into my Dell. When I upgraded to 10.04 yesterday, I lost the wired connection. The wireless connection still works fine, but I have not been able to get a wired connection. Also, most online solutions reference the Network Manager, which is nowhere to be found.
Anyone have any solutions? I would be willing to revert to 8.04 if needed, as that worked fine, and obviously I quite regret the upgrade!
