Networking :: System Hangs When Nfs Connection Is 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 desktopworks properly. Unless the server comes alive, the nfs directories are mounted and the connection is lost again.I'm not really sure if this is a networking case, it could also be KDE related, but I figured this was the most reasonable place to put my topic in.My hardware:

linux-bbdu:~ # lspci
00:00.0 Host bridge: Intel Corporation 82G33/G31/P35/P31 Express DRAM Controller (rev 02)
00:01.0 PCI bridge: Intel Corporation 82G33/G31/P35/P31 Express PCI Express Root Port (rev 02)

Ubuntu Networking :: Lost Wired LAN Connection After System Freeze?

Sep 23, 2010

I installed Lucid a week ago and have been having a blast with it after a two year break from Ubuntu (been using Mandriva). So the other day I went to hibernate the system and it froze. I naturally did a hard reset and when I log back in, no network connection. That is to say, the system tray says it's connected but there is no LAN light on the router or network card. ifconfig shows it's connected too. When I boot into XP (cringes) it works just fine.

No specifics ATM but the card is a D-Link PCI with a Realtek R8***** chipset

Networking :: Connection Lost To Gateway?

Oct 8, 2010

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?

Networking :: Lost Wireless Connection

Aug 5, 2010

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.

Ubuntu Networking :: Lost Internet Connection - Now Can't Get It Back

Jan 23, 2010

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.

Ubuntu Networking :: Connection Lost After Router Restart

Aug 11, 2010

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

Ubuntu Networking :: Lost Wired Connection After Resume?

Jun 27, 2011

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)

Ubuntu Networking :: Lost Internet Connection When Upgraded 8.04 To 10.04?

Jul 25, 2011

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!

Ubuntu Networking :: Lost Wired Connection After Update

Sep 1, 2011

After I updated ubuntu 10.04.3 and restarted my PC, something weired happend and my wired connection was completely lost. I tried different things but it seems that I have lost my ethernet connection. I only have ethernet card and the interface was set to eth0 which is not recognized anymore.

The /etc/network/interfaces includes the following commands, which btw I tried to play with a bit by commenting and uncommenting the lines but was not helpful (but this is the original one):

Also in /etc/udev/rules.d I deleted 70-persistent-cd.rules hoping that it would be automatically regenerated but it did not,

Here are some messages I get :

Networking :: Detecting And Logging Lost Internet Connection?

Dec 8, 2010

We have an Asterisk machine that we suspect periodically loses internet connectivity, causing all calls to drop. First, would this sort of thing be logged anywhere out of the box? I haven't noticed anything in /var/log, but that doesn't mean it's not there. If this is not typically logged, how I might go about logging it? I'm currently running a bash script from cron every 5 or 10 minutes which pings Google and writes success or failure messages to a log file. This works fine for extended outages, but if the internet connection drops and comes back between cron runs, it won't be caught.

Networking :: Lucid Lynx Suddenly Lost Connection ?

Mar 5, 2011

All of a sudden without rhyme or reason, My Lucid Lynx install stopped connecting to my network. This was without any intervention from me as I did not modify install or change anything prior to this happening.

What I have gathered so far is that upon initial boot eth0 seems to always be disabled. So I ifconfig eth0 up to bring it back online. All the settings in the network applet seem to be intact for my manual network that has DHCP disabled. Let me re-iterate that these settings worked fine for months then all of a sudden something went belly up. The same machine will connect fine with the same settings from within Win7.

ifconfig command shows both eth0 and the loopback interface but eth0 never manages to secure the 192.168.1.3 address that it should have. ping 192.168.1.1 returns "Network unreachable" so it appears the connection is being cut off at the machine and not the router. I did check to make sure the connection was even recognized and it sees the wired connection going to the router, but nothing else.

/etc/network/interfaces only shows two lines regarding the loopback interface and nothing else; eth0 seems non-existant within this file which I find odd.

Fedora Networking :: Ethernet - Suddenly Lost Internet Connection

Jun 16, 2011

I installed Fedora today, and I automatically had internet connection, I never had do configure anything myself. Then, I was playing around with VPN for a good while (trying to set up the VPN connection to my University), and now, I suddenly lost my connection to the internet!

But only Fedora can't connect anymore, the Windows PC has connection as well as my Mac OS X (I dualboot Linux on my MacBook). The Ethernet connection works as well, when I unplug the cable, Fedora gives me a message, but I just don't get into the internet!

Does anyone have an ides what I have to do? I don't know anything about network connections and I'm new to Linux...

I already restarted the Computer, but that didn't work, and Google didn't really held either.

Ubuntu Networking :: Lost Connection To Network Printer - Re-establish It?

Feb 12, 2011

I have had long term access to a networked HP Photosmart printer but now I get the following message:

Unable to open device hp:/net/Photosmart_C5100_series?ip=192.168.0.161.

when trying to access it.The ubuntu desktop is wired to the router as is the printer and another iMac wirelessly can still print to the HP. HPLIP status shows the icon for the printer but with a red x indicating no connection to it.The only recent network change was the removal of another router from our network. (service is DSL via a combo modem/router from service provider which previously was connected to a Dlink router which has now been removed from the chain b/c was redundant to the modem/router)

Ubuntu Networking :: Internet Access Allowed When VPN Connection Lost?

Mar 16, 2010

As I view it, Ubuntu has a great security risk in that it still allows internet access when the VPN connection has been lost, for whatever reason. As it is now, when the VPN connection fails you get bumped back to using your regular IP, and whatever you are doing becomes transparent to anyone watching. This is simply unacceptable for an allegedly secure platform. Does anyone know of a way to fix this with a script/program, or is there a distribution/OS that allows this? Windows re-dials the vpn automatically, but still allows internet access in the mean time.

Ubuntu Networking :: When Switch Rebooted Network Connection Lost?

Apr 19, 2010

When there is a power failure at my university for about 30 minute, my computer stays up because of a UPS, but the switch it is connected to via ethernet is reset. After this, my machine loses network connectivity until I manually select the network using nm-applet.

In System -> Preferences -> Network Connections, the network has the "Connect automatically" box checked.

However, in /etc/NetworkManager/nm-system-settings.conf, there is a line that says:

Code:
no-auto-default=00:30:48:b0:11:07,
and that is the MAC address of the ethernet card.

I'm running Ubuntu jaunty.

Ubuntu Networking :: Lost Wired Network Connection After Installing 10.04?

Nov 1, 2010

I had some problems installing 10.04, which I'm not going into here unless I have to, but it appears to be up and running now except my PC can't access the network, even though it's wired. This is the first time I've tried putting on a new build by myself as my son always used to do it (my PC used to belong to him many years ago, and is old, like me.)

Ubuntu Networking :: Wireless Connection Lost When Using Battery Power?

Dec 18, 2010

I'm running Ubuntu 10.10 netbook edition on a Dell Mini 9 - worked around a few wireless issues on setup and connectivity has been fine, but now I'm suddenly losing wifi when I unplug my AC adapter. It still shows me as connected, but when I try to view web pages in Chromium, it will load pages for a few seconds, and then suddenly cuts out - though it still looks like it's trying to load the page.

It's the same if I boot on battery power - it will keep trying to connect to wifi but won't until I plug in the adapter. I'm assuming this probably has something to do with my power management preferences in battery mode, but I'm still pretty new to Ubuntu, and I'm not sure how to fix this. I've played with the options in power management, but I have a feeling there has to be more. Can anyone help me? This has been really frustrating.

Ubuntu Networking :: Internet Connection Lost After 10 Minutes Surfing

Apr 23, 2011

I do have a problem with my internet connection at home, I've a Huawei router and ubuntu 10. When I connect to the internet whether wireless or wired I become able to surf the internet for less than 10 min then it cuts off! and to be able to surf it again I need to restart the whole system!

I used this command to restart the networking but in vain
Code:
sudo /etc/init.d/networking restart

On windows I do not face this problem with the same internet connection. I do not face it either when I'm using my campus wireless connections using ubuntu/windows!, so the problem is related to my home connection+ my OS.

Ubuntu Networking :: Wireless Connection Lost After Closing Laptop After 9.10 Upgrade

Jan 16, 2010

I have an odd problem in that my wireless connection is okay until I close the laptop. When I open it back up, I'm unable to reconnect. This problem first occurred after upgrading to 9.10. I can reconnect after restarting. I tried several things before breaking down and reinstalling 9.04. After installing 9.04, everything works great. Any suggestions on what is going on before I try upgrading to 9.10 again? I have a Dell D600.

Ubuntu Networking :: Connection Lost On Opening Webpages - Server Not Found

May 10, 2011

On a school network the Windows and Mac computers connect to the internet with no problem. The Ubuntu(10.04) computers are connected and work on the internal network but have major issues going out of the building. I can get to one or two webpages to open and the connection dies...Server not found. Ping within the network and there are no lost packages, if I ping outside many lost packages.

We are using SonicWall and think it could be blocking...but why only Ubuntu? This is the same behavior for Firefox and Seamonkey. It's also the same for the thin/fat clients and standalone units. I did try a fresh install with no effect. The internet actually works on the one machine with ubuntu 9.10. I brought a machine home and it connected to the internet with no problem.

Two things I can think of that would of caused this are:
1- we keep getting windows about missing applets, someone may have clicked delete
2- I connected a server to run fat clients w/ LTSP and discovered my server and the schools were handing out the same ip's.
