I loaded up OpenSuSE 11.4 on a HP DL360 G5 64 bit server. When the server boots up, I can connect via the wan or the local network segment. After some time, I will lose the WAN connection. If I ssh back into the computer from another computer the WAN connection can connect again for a period of time. The WAN connect is from the Internet. The firewall is off and so is AppArmor.
View 9 RepliesI recently upgraded a 11.0 installation running on Xen Server to 11.3. I am experiencing frequent network disconnections now. The ip address and default gateway is assigned statically. However, the system seems to ignore the default gateway after a while. Then after several minutes it seems like it comes back.

When my sessions suddenly die and I have to coax it into routing correctly again.
I'm using OpenSUSE 11.4 and the GNOME 3 packages in the GNOME:STABLE repository. I maintain an application and have a remote Mercurial repo hosted at BitBucket, which requires SSH to do any push/pull operation.
My passphrase is just that -- a phrase, not a word -- and it's too long to type accurately without seeing it. I cut and paste it from a web page. When I'm asked by a console app for the passphrase, I can do that. The GNOME SSH passphrase dialog does not allow pasting or dropping, so I can either try to type it or hit cancel. Normally, ssh-add provided a way around this; it would ask you for the phrase on the console, and I could paste it.
This doesn't work in GNOME 3. ssh-add still asks me for the passphrase, but when I try any operation that requires the key, the dialog pops up again. How is it possible to get ssh-add to work, or (preferably) get rid of the dialog?
As soon as i'm starting to copy a large file enough file (>700Mb) to my ubuntu box (connected to an Asus router via wifi) from a Windows 7 client (connected to router via ethernet cable) i get a dramatic drop in speed. upload starts at 1,0Mb/sec with a ping to ubuntu box at <1ms, and in 2 minutes it drops to 200kb/sec with a ping of over 1000ms! The ping increases with every second in a linear progression.
To exlude router as a possible problem copying to a windows 7 notebook connected to router via wifi results in an average of 2,7Mb/sec with an average ping of 150ms.

I'm running F13, using Network Monitor to control my DSL connection. Until recently, all was well. Then, about a month ago, I tried changing my DNS numbers for reasons that seemed good at the time. Being properly paranoid, I kept my old DNS numbers in a text file. It's a good thing, because from then on, every time I needed to reboot (I only reboot for a kernel update, only shut down for hardware issues or a power failure.) I had no DNS until I copied them back into the configuration, disabled and re-enabled the connection. We've been having some work done here on the exterior, and every time the workmen come they manage to drop the power on the room the computer's in. I don't know if it's significant that all of the DNS losses have come after a power "failure," but it's worth mentioning.
View 13 Replies View RelatedAfter installing 11.4, I need to type in the command to update the firmware for a broadcom wifi adapter. Then I needed to reboot, twice, before the system knew to use the adapter (where the adapter wifi light goes from orange to blue).
Then I needed to add my wireless network and type in my key. But the key does not take. If I click on my wireless network icon, it just re-asks for the key and does not connect nor give any other message. Network icon continues to display no connection.
So I need to reboot again.
When the system starts again, the adapter is blue, I click on the icon for my wifi network and it connects without asking for my key and I can then set to start my wifi by default.
Now my wifi works fine.

View 3 Replies View RelatedI installed OpenSuSE 11.3. The only "extra" package I put in after the install was VirtualBox-ose. The firewall is disabled. I gave the machine a static IP address. I can get to the Internet from the machine. I enabled sshd to start on boot with "chkconfig sshd on" and also verified the service is running on the machine. I can ssh user@localhost from the machine as well.
When I try to connect to SSH from another machine, I get a connection refused. I verify that the firewall is down. I also try to get to VNC -- same problem: Connection refused. I ping the machine for fun. If I try to SSH again, it sometimes gives me a logon? I would check the server logs for the connection refused, but I wouldn't know where to look. I started in /var/log/messages, but nothing seemed to jump out there. I also find it strange because I can RDP to a windows guest running under VirtualBox. The Windows guest uses Bridged Network and DHCP.
I also find it interesting that I sometimes type a "ping google.com" from the 11.3 box and it will just hang - no output. Then I open firefox and get to the internet. All of a sudden, ping starts to give output. Could this be a neetwork card issue? A configuration issue? I don't know where to start.

View 4 Replies View RelatedHere is the layout of my network:My cable modem plugs into eth0 on my ubuntu server which acts as a firewall (shorewall) and dhcp server to my lan. A dd-wrt access point is plugged into eth1 and then a bridge connecting my xbox360 and another bridge connecting a desktop computer.Everything works pretty well, except a few times a day, my network will just shut down. The wireless on my macbook and my wife's laptop will just shut down, and if my xbox is running, it will lose connectivity. It will be down for maybe a minute or two, and then come back up like nothing ever happened.I never had this problem when I had just a dd-wrt router running everything instead of my server.When I ssh into my server afterwards and run dmesg, this is what I will get:

My network seems to be dropping every few minutes to few hours. There are a lot of networks in the area (apartment in NYC) and I wonder if it might be due to competing traffic. Any ideas for how to tell what channels other networks are on? or other modifications to router settings that might improve performance in this situation?Additionally the "Invalid Misc" in iwconfig is counting quite quickly.
View 4 Replies View RelatedI am relatively new at Linux and am having some problems with an install of openSUSE 11.2. I installed 11.2 on my Thinkpad X31 dual boot with WinXP. It seems to work very well except the network. I looked up swerdna's instructions on setting network cards up. I used YaST to try and set the system up as described in swerdna's instructions. Everything looks fine my network card and wireless card show up in the overview settings screen and everything sets up fine. But when I exit YaST the network doest show up no icon in the system tray and it doesn't even try to connect.
I did go into hardware to see if it was identifying my hardware and my network card shows up as "Thinkpad R40" and the wireless shows up as Cisco Aironet Wireless 802.11b. As far as I know this is correct. I have tried three other distro's and this one has gotten the closest to working so far.
the thing is that I cant use Network Manager to connect to Internet, because it simply do not connect. The connection, although, awailable throught yast when i choose "traditional method with ifup", so everything is just fine, but if i need to reconnect, i have to reboot. How do I setup a !working! connection through Network Manager, or maybe i do not do something properly.

I have an Ubuntu box, 11.04 x64, running on a Dual Opteron SFF box (iWill ZMaxDP... pretty old machine). Up until a few weeks ago, it was acting as a Windows 2008 Server, but i moved it to Ubuntu.
Anyway, the machine will not stay on the network for any amount of time, without falling off... I have changed network cards, cables, ports on the switch, etc, and nothing seems to work. I have a Windows 2003 box giving out DHCP addresses, and for a while, i actually tured that off and setup a second Ubuntu box to give IPs... it made no difference. The box gets an IP, and can ping outside for a bit (2 min or so) and then just looses connectivity... ifconfig shows it with an IP (i have tried both Static and DHCP config) and nothing seems to work...

I have a windows installation (partition) but have installed into freespace on the same drive using the auto-partition manager, etc, and everything is fine. I got my network going fairly easily by going Preferences > Wireless and inputting SSID and WPA encryption key (PSK). My router issues an WLAN IP, I can get on the net, I can see my other Windows PCs on the network, I can reach my router, and all is good.So after several hours of mooching about and looking at things, I have updated all the Linux packages via Synaptics (following a prompt to update everything) including GRUB. My dual boot now shows two versions of the OS:
GRUB 1.7~Beta4
Ubuntu, Linux 2.6.31-19 - generic (I am booting this one)
Ubuntu, Linux 2.6.31-14 - generic
I also set up my HP F4580 printer over wifi on the network though with slightly incorrect drivers (for the F4400 series as this was recommended at the closest match). It works, and I can print a test page no problem.The only thing is that now (since doing all that) Ubuntu seems to periodically drop my connection to the network and then request the network PSK again, but when I enter it, it spends time trying to renegotiate but fails, and then re-requests the PSK, over and over and it never reconnects. I have to reboot and then I can connect again (automatically), until it drops at some random point (like 5 or 10 mins later)
I set up the web/backup server for our department and I'm having some major issues. Firstly, the server seems to be dropping the network connection periodically. I checked all of the logs and it appeared to be an IP6 issue as the only message that seemed to correlate with it was "eth0: no IPv6 routers present" in syslog. I added "ipv6.disable=1" to my boot options in menu.lst and this seemed to take care of the problem. However, I woke up this morning and the server was back down.
This didn't seem to take care of the problem. It seems to occur when my automatic backup scripts go through. I have several BASH backup scripts that use rysnc over SSH to backup several computers to the server and the server to my desktop at home. I was able to trigger the problem a couple of times running the backup script this morning. Now, I'm getting the following error when running the script, instead of losing the network connection:

I tried booting with a previous kernel to see if that was the problem and I'm still getting this error. I've searched through all of the logs that I could think of to try to track down any software based problems and I just don't see anything. In the past, whenever I've run into such serious with a Linux box that popped up out of nowhere, it's always been a hardware failure. I've currently disabled all of the backup scripts and I'm going to see if it lasts through the weekend.
We are having an issue where our network connection is dropping on our server. Everything was working for about a month without issues then suddenly we experienced a network outage. Here is what I found in our logs. Rebooting the machine was the only way to have everything come up.
