CentOS 5 Networking :: Loosing Network After Few Hours?
Jul 31, 2010
I have a problem with network on centos, after i restart the server it works for few hours/couple days, and the network is dropped. - no errors in the log, only that "Network is unreachable" I do 'service network restart' comes back on- directadmin, dns, awbs- everything works good, but only for few hours(never longer then couple days), and then it is dropped again. I searched many forums, and on one them someone wrote that it is because that static IP was used on the same network by other machine. I had a different server running with that ip on my network before, but it was few weeks ago, and there is no other server connected to the network right now (I have one desktop connected with dynamic ip, and it has no problem), and i still have the same problem.
I was suggested to set a cron jobs to restart network every few hours- i thing that is not a solution. Does anyone have any idea what could be a problem? Anyone had similar problems? What could be the reasons for the network to be dropped after few hours? Here is latest 'dmesg' output after losing network:
[root@server ~]# dmesg

Running Debian GNU / Linux 5.0.4 on an older Gateway tower. Have been using this for a year now but it seemed lately that the browser was loading pages slowly. I checked the Network Icon and every time I check it indicates "disconnected" then refreshes and indicates connected. The log makes references to redat, which my machine has nothing to do with? I checked the system logs and get the following repeated messages:

I am trying to install CentOS 5.2, and the installation ran out of disk space after running for about 2 hours.I checked the FAQ, and it said 1.2 GB. The disk is 3 GB. The default install was selected, and I think that it checks for sufficient available disk space before installing. Still, it ran for quite a while before announcing that it was out of disk space.The Installation Guide is not very helpful, since there is a blank page where the disk space requirement is supposed to be. I just picked the default installation. A search of the forums on "not enough disk space" did not return much.

I'm migrating a server form CentOs to Ubuntu 11.04. I migrated the users, moving the config files and gaining the access prompt for all the users just when I modified adduser.conf and login.defs, changing valid uid and gid to start from 500 instead of 1000. When I try to copy the files from old server to the new one, either with rsync or cp -br, the system set to 0 uid and gid. If I explore the mount point, connected with sshfs, I can see the correct configuration, either as names or as numeric data.

Opensuse 11.2 - wired internet connection
I keep losing internet connectivity from within OpenSuse. I've had ubuntu/kubuntu beforeand never had a problem. I installed opensuse and now after a few minutes of browsing I'll lose my internet connection.I also dual boot into winXP without any problems.I noticed that when the connection is lost I can't even reach my router - which is where I'm getting the wired connection from.So it's not just the outside internet but the local network too. It only happens within opensuse.

I have a computer home that I use a web server and I had Lenny in it for about a year and didn't experience any problems. Recently I needed to update to Squeeze just to be able and use part of my server for a game(which I couldn't compile on Lenny). I renamed every "lenny" word in the /etc/apt/sources.list with "squeeze" and ran dist-upgrade. Everything seemed fine(minor some "link not found" warnings). I also had some minor problems with the mysql configuration after the update but I managed to fix them all. Then I noticed that after some hours(not sure how many) I can suddenly not reach my computer via ssh. Neither can I visit my website(even from the local network). The computer doesn't appear either in the router's "attached devices" list. My other computers have no problems so it can't be a router issue.Pinging from the server to the outside world doesn't work. I tryied "sudo /etc/init.d/networking restart" and that didn't do anything. The only way to fix the problem is by rebooting but then again after some hours the problem is still there. Do you guys have any idea what the problem can be?

I have the bar at the top configured to display the time but it is displaying 12 hours out.For example, it's now 16:49 but the time is displaying as 06:49. If I click on Adjust Date & Time it has the correct time in there and it is configured to display 24-hour format and is in the correct time zone. If I switch to 12-hour format it displays 6:49 AM which is clearly incorrect.I can't fix it because it thinks the time is correct when I try to change it.

I am running a LAMP system with CentOS 5.4.The clock just automatically shifted backwards by 19 hours and 30 minutes crippling some of my reports and probably damaging something else along the way.The router supplying IP to this server is a DD-WRT and shows proper time.By the way what does that mean? time drifted by that 33.667 ms?

I'm having a really weird, annoying problem: approximately every 10 hours, like clockwork, my internet connection stops working. (Last time I had the presence of mind to check the uptime: it was 9 hours 48 minutes; this was maybe 5-10 minutes after it happened). My existing connections (IRC, etc.) keep working fine, I can access my home router's configuration page, and `ping` still works, but otherwise new connections invariably time out (whether it's a web browser, git/subversion, or whatever). I have found no solution to this other than rebooting.

I've been experiencing one issue in my opensuse 11.3 KDE, the thing is when leave my pc downloading a file, it disconnects after a period of time, I don't know when exactly. I connect to internet at boot time via DSL modem, when I was setting up my connection I noticed, that there is an option "idle-timeout" I set it to zero "0", I know that my pc donwloads all the time and speed do not drop, why then it disconnects?, it disconnects even with higher numbers of idle-timeout. It happened on the other laptop too, so I need every time to "rcnetwork restart" to get it back working

I noticed that every, say, 5 times I boot CentOS 5.4, a find search is initiated that takes several hours.
For example:
find . -name rd=rmdir -print
I'm not sure if it's related, but, I do have a "alias rd=rmdir" in my .aliases. Would changing it to "alias rd=/bin/rmdir" avoid this problem? I'm using zsh. Is this search necessary?

I do randomly (as far as I know) loose my wireless network connection. The only thing to do then is to restart my router and after that it works for a while. I know this is not a hardware issue because I don't have this problem with KDE, only in gnome. I think this problem occurred after I started using 10.04, but then I changed to KDE and forgot about it. But now I'm using gnome again and loosing my network connection over and over drives me mad

I'm Using the latest Kubuntu 10.10 with the default network manager -- which I think it's called Knetwork manager.
I have set up a static IP by adding a new connection using this manager and then clicking it so that it is used to connect. But as soon as there is a computer reboot the connection falls back to the original autoeth0 which has dynamic IP on and which I cannot change or delete.

I have a Cent OS dedicated server, not sure what version though as I'm new to Linux. How do I find out what version I have? Is there an anti virus or security package that I can install on my server which can use Cron Jobs to do a scan every 12 hours.

I just upgraded from Ubuntu 9.04 64-bit, to CentOS 5.5 64-bit and my RT-73 USB network card doesn't seem to want to function. It always worked fine in Ubuntu by default (plug and play). Is there some setting I need to make to get this working?Even BT-3 (which is quite old) recognizes the RT-73.

I have an LG R-450 laptop with Ubuntu 10.04 installed in it. When I connect him to a network (either LAN or Wireless) it stays connected for a few minutes and then Just disconnects (without showing any sign of disconnection except no internet/skype/dropbox). Only way to renew connection is after startup. The network controller is SIS 191 Gigabit Ethernet adapter.

Periodically, about 3 to 5 hours, Ubuntu disconnects from my wi-fi network and doesn't reconnect until I restart the router.This is an Ubuntu specific issue, since it doesn't happen when I boot into my Windows partition, and it doesn't happen to other computers on the network.

I have a minor Internet issue. I have a static IP address with the modem acting as a gateway only to my ISP. My Ubuntu server hosts my public IP address and I use pppoeconf to connect. Every 3 hours I lose Internet. I have wrote a short script to reconnect. I doubt that it is my ISP trying to renew that often.

We have a NAS application which can be accessed by both HTTP and HTTPS connections.
The issue we are facing is that the tcp server instance that initiates the HTTP access dies after a few hours of inactivity(the NAS application was kept idle for around 10 hours). However, the tcpserver that launches HTTPS connections remained running.So the connection failed through HTTP access but the connection succeeded through HTTPS access.
The converse has also been observed where the tcpserver for HTTPS is dead but tcpserver for HTTP is running.
The version of tcpserver that we are using here is ucspi-tcp-0.88.tar.gz.
I have the following queries:
a)Has anyone faced the same problem before?
b)Is it an issue with this package version of tcpserver ?
c)Will upgrading to newer versions of tcpserver bail me out of the issue?
d)Also, could anyone let me know what are the possible causes for the tcpserver to die ?

I have a hp dv3 laptop which dual boots Win7 and Ubuntu 9.1 64 bit. I have no issues with my wireless adapter in Win7, but I lose connection after a couple of hours in Ubuntu. When connection is lost it is not possible to view any wireless signals, the adapter is basically turned off. The only way to restore the connection is to reboot, then Ubuntu will again automatically connect to my WP2 encrypted router. My wireless adapter is a AR928X made by Atheros.
