Ubuntu Networking :: Network Instability Of Late
Jul 31, 2010
No shared files/folders/drives and printers vanish. Most of the time re-booting will be the answer, but not this time I have 3 Ubuntu machines networked with two XP machines. one hard wired and two wireless on the 10.04. ONE wireless is networked right now and can see the other Ubuntu machines and the Windows machines and the printer. The other two are blind as a bat The two XP boxes one hard wired one wireless .. see each other. But see nothing on the Ubuntu machines that are down. Would like to fix this issue PERMANENTLY and quit screwing with it every couple of weeks Tried re-installing everything green in Samba and that did nothing. follow up edit managed to get the printers system back up on all on the net just by re-booting.

from time to time, wireless connection gets very slow, and i have to make it reconnect, and some times, restart fedora. The wireless card has an Atheros AR5212 802.11abg NIC (rev 01). This happens mostly when i use Tucan Downloader, or Torrent, meaning, heavy internet use.

I have Centos5.4 loaded on a late 2008 MACBOOK Pro and would like to get wireless working. I've attempted to download the broadcom driver and create a driver module with no luck.
Using these instructions....

Just upgraded to 10.04 on Wed and noticed an instability. It's intermittent, so can not tell you what triggers it, but when it kicks off a commandline screen comes up, with a command pointing to some battery monitor software, and I have a desktop, so no battery and wonder why my machine has a battery monitoring software, when none should be installed. Anyway the screen stays up momentarily, then the system tries to go into something like a screen saver and I get all garbage on the screen, loose all ability to control and have to perform a hard reboot to recover from this.

I'm having stability problems with opensuse 11.3. On three occasions when you login the system is rebooted. Also blocked the entire system three times. This happens shortly after starting and running amule, but not if due to this application. Use kde 4.5, these problems are happening in the last week.

I used Easy Tag to edit my songs' ID3 tags. Banshee reads them fine but Rhythmbox misreads them! For eg., blink 182, Blink 182, and Blink-182!!! Apparently it's because Easy Tag makes ID3v1 tags while Rhythmbox read ID3v4? That's SO stupid! What am I supposed to do now? I saw RB had a bug filed but it got closed because "it's not a problem with rhythmbox, it's a problem with ID3 tags." RB should be able to read them! That's ridiculous. So how do I fix the tags? As for Banshee, anyone else move from version 1.6 to 1.7.6? The new one crashes everytime I use it. It's simply awful. And this is supposed to lots of bugs fixed? It's the new stable version? What a joke! How do I fix this now? Or better yet, how to go back to version 1.6? ^ Never mind, I downgraded it. Still have the rhythmbox problem! I'm using Ubuntu Lucid 64 bit with Gnome. RB should be able to read them! That

I have a very frustrating stability problem on my Workstation where I run a Slackware64 Current installation. The problem is, many programs just crashes, after they started, or after a quit short while. Affected are Firefox, Thunderbird, Krusader, Amarok, Konsole, and many other programs. The second problem is, if I downloaded a bzip2 archive, it is corrupt. I downloaded many archives, from other mirrors, and all corrupt. I had installed, the Multilib-packages, thought they would be the reason for the problems, and installed the standard packages of glibc and gcc. No changes. Then I upgraded the kernel from 2.6.33.4, to 2.6.35.6. (Compiled it myself) Nothing better.

I'm getting one of those an 11" MacBook Air with 128gb SSD. 64gb might be too little for dual booting. Of course, I'll run Ubuntu on it. I'm choosing this hardware, because of the great form factor, aesthetics, trackpad, and ability to run OS X (as a UX designer, I want to do competitive analysis of the OS).It will be my first Mac. Any advice? Got tips on what I should start learning, getting used to, etc?

I recently followed a tutorial on how to get OpenLDAP running with Samba on Lucid. It worked pretty well.Here's my very frustrating problem with it. For the first 5 - 10 minutes after rebooting, password handling (possibly PAM?) is hosed, including for users in LDAP authenticating via Samba.In fact, I think the only reason I can SSH into the machine during that window is because I happen to have certificate authentication enabled and my client uses that.When I try to do a sudo command after logging in, though, and have to enter the password, it hangs. I've searched logs and haven't come up with much.I *think* it's related to this bug, but I'm not sure.And here's what's killing me ... it's not easy for me to figure out how to ensure that slapd starts before smbd and rsyslog (I read somewhere else that it needs to start before that for some reason) b/c most of the jobs are upstart jobs, but slapd is not.By default it runs at S19 in rc2.d, and I've tried manually lowering that as far as S05 or S07, but I'm still having trouble.

I skipped over Jaunty on my main desktop because Intrepid had been working perfectly for so long. Finally took the plunge to Karmic, and have had major instability problems. I cannot trace them to any particular program I am using. At first it seemed related to power management, since it would lock up every time it had a period of extended inactivity. I have disabled ACPI in my BIOS (I think), and any power management settings I could find in gnome to try to troubleshoot. That seems to have helped, but it still happens semi-regularly, sometimes when I am in the middle of using it. I have tried checking logs and googled anything that seemed important. ie a message in kern.log reads: Clocksource tsc unstable

I was using an extremely common debian based distro, but I have been rebooting my pc non stop for the last two days trying to get my nvidia fx5200 drivers to work. (it is just IMPOSSIBLE to disable the nouveau driver, i have tried blacklisting it, editing xorg etc, nothing works) I need to know if there are many issues with getting nvidia graphics cards to work in debian. it seems like the last 18 months worth of releases on all the other debian based distros have completely broken all support for any nvidia card made prior to 2011. i know for a fact that in windows xp all my hardware works perfectly, but i really dont want to have to use that, i have been a linux user for more than 5 years now, but all i am really looking for now is reliability. i want to be able to use the nvidia-173 driver, as i know that this allows me to watch the movies i take on my dv camera, and ......

I had centos 5-5 server with 6G of RAM and 4 core cpu 3GHZ i installed bind 9.7.1-p2 on my server with multi thread support there are a lot of dns requests on my server , about 2500 Packets/sec and 3Mbit UDP traffic but my server response week to most of them.
For example when i use nslookup or dig command to query Yahoo.com the response from server maybe deliver about 5 Sec or become timed out , but sometimes response time less than 1 sec!
I don't know why, perhaps kernel works week so i decided to do the following :
But the problem didn't solved
I previously had Freebsd with same version of bind and same configuration and everything worked fine.

if I reboot the computer, I get the grub menu and am able to choose between Win7 and Fc15. A couple of times during installation the screen flashed black and diplayed a message for a brief second. I can't read that fast but it says something like "DRM nouveau- unknown or unsupported chipset" and one more line that I can't catch. When this happens, I see the pre-login loading screen, the one that shows an icon of a hard drive, network, and so on as each resource is secured. I can log back in, but this starts a new session- it doesn't remember what I was doing. I had to redo the install and setup several times because of this.
I can log in and so on normally, but the black screen and message will appear at random, forcing me to start all over, which is really frustrating. what's going on? Is it the video card? How do I install a driver for it? Also, the hard drive in question has been through a lot. could it have a bad sector or something? Windows didn't even want to "see" it, that's why Fedora is installed on there.

I opened GParted to create a new partition on a new drive. He wanted me to create a partition table first which I did, and it was created directly without any prompt like im used to see when creating partition. So I recognized too late, that i actually created a MBR on one of my 6 1TB raid5 drives. Not beeing sure if the ne MBR was really written, I have opened ubuntu disk utility and clicked on the check raid button. It directly made a resync. After the resync, mdadm --detail /dev/md0 told me everything is ok and synced. Then I wanted to mount it with:
mount /dev/md0 /mnt Then I get the following error: "mount: wrong fs type, bad option, bad superblock on /dev/md0, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so" I think I just killed my raid5 ;(
I shouldnt work on my server when im tired and when I actually have no time ;( My last hope is the fact, that "Disk Utility" shows that there is a .0 TB ext4 volume on my raid (see screen below) [URL]

So recently I've been trying out openSUSE, along with a few other distros, for use on my HTPC. Previously, I'd been using a hackintosh build, so my external media storage HDDs are all formated HFS+. It was actually surprisingly easy to get openSUSE to mount them for both reading and writing.
Only thing is, XBMC has been pretty unstable on all of the linux distros I've tried, and I'm wondering to what degree the HFS filesystem might be affecting things? It would take a fair bit of juggling -- or going out and buying a new multi-TB HDD -- to clear out the disks in turn so as to reformat them with an ext filesystem, but if that would help me get a more stable HTPC with opensuse -- the linux distro I've settled on -- it'd be worth it. I'll paste a link to the log from an xbmc crash, in case that would be helpful, but really, I'm just curious, since I don't really know all that much about how different filesystems work or anything, how much extra strain does the filesystem translating entail?

I just got fedora 13 today and put it on a slightly older computer to mess around with it, and two things I realized.
1. I installed Flash player through a program called easyLiving, but when i play flash games online like on armorgames, everything will play fine, but sound will play about 2 seconds late with actions.
2. I can't play .wmv files from my MP3 player, I found some codes online and installed them, but now it just looks like I have 3 different audio players in mozilla and I'm not sure which kind to enable, and I still can't play .wmv movies. (I actually believe that problem 1 is unrelated, because I noticed it before I started downloading different audio players.)

I installed Fedora 13 and on my new laptop and tried upgrading to F15 and it gets stuck at "Late init script for live image".I've been searching and seen threads in the F15 Dev forum that I cannot reply to. I do not have akmod or kmod on this machine.I can get to a terminal, I have an SSH Server I installed before it broke. When I press ESC at the boot screen the last thing I see says "Late init script for live image"

On my debian lenny OS I have an external usb hard disk I would like to automount it at boot. So I edited the /etc/fstab file in order to automount /dev/sdb1. It worked without problem. Then I recompiled the kernel and, as consequence, /dev/sdb1 changed to /dev/sdc1. I started playing with udev in order to match the now called /dev/sdc1 and to change its name in /dev/maxtor (being maxtor the brand of the hard disk). Obviously I edited also /etc/fstab: /dev/sdb1 is now /dev/maxtor.
The boot automount doesn't work anymore. On the boot sequence I can read the message "Mounting local filesystem...mount: special device /dev/maxtor does not exist FAILED". But when I log into the system I can run the command "mount /dev/maxtor /mnt/maxtor" and it works! So, IMHO, my udev rule is correct otherwise also the manual mount wouldn't work, right? I have to tell to udev to create /dev/maxtor BEFORE the boot automount process.
I tried to delete my udev rule and to edit /etc/fstab changing /dev/maxtor in /dev/sdc1 (the name udev gave to my hard disk after kernel recompile, before was /dev/sdb1) and it didn't work: on boot process I always see the "Mounting local filesystem...mount: special device /dev/sdc1 does not exist Failed". Then I tried to change /dev/sdc1 in /dev/sdb1 in /etc/fstab and to reboot with the old original kernel and int this way it works. With my compiled kernel, the OS seems to have lost the capacity to detect my device node correctly.

I ran this command on a new centos 5.6 64 bit install today: rpm -Uhv http://apt.sw.be/redhat/el5/en/x86_64/rpmforge/RPMS//rpmforge-release-0.3.6-1.el5.rf.x86_64.rpm Sadly I failed to read a warning about setting priorities as a prerequisite to avoid rpmforge overwriting base Centos packages.
The install is a standard Cpanel web/email server and seems ok at the moment. My concern is I intend to clone this VS about ten times. Should I be concerned and if so, is there any way I can safely undo the rpmforge install? Eg can I use "rpm -e rpmforge-release-0.5.2-2.el5.rf" without vile consequences?

I have installed qemu/kvm and created a Bridged network connection which works just fine(Windows 7 VM won't work in NAT mode.)
But when I try to use NetworkManager it says that I have no network connection because the network isn't managed, (I set the settings in ifcfg-br0 and ifcfg-eth0 to be managed)
The real problem is that now I can't use my VPN connections (I have many) in NetworkManager.
Is there a way to have both of these pieces of functionality?
I am using FC14

I am totally new to Linux and have just installed ubuntu 10.10. After configuring the network interface via dhcp I started getting these messages that come in so frequently I can't configure anything else.
[87.186415] Stack:
Why I am getting this messages and more importantly how do I get rid of them.
The installation is on a VM on Hyper-V.

I recently fixed an annoying problem and I thought it would be nice to share my solution here. The problem was that after a cycle of suspend/resume, Network Manager would only auto-connect to the same network as it was previously connected to. So, for example, if I suspended my laptop at home, and then I went to school and resumed it, it would try to connect to the home network, and then just give up. It would not connect to the school network unless I explicitly told it to.irst, I'll describe the fix. If you're having this problem, you can this. Copy the following:
Code:
#!/bin/sh
case "$1" in

I have a system running a very basic LTS install (10.04). Ubuntu has been setup with very little additional packages. No GUI. Once it's booted to a prompt for the first time I add the following packages,
cups cupsys ssh pi memtester nfs-common
aptitude safe-upgrade
At this time I don't have additional information on exactly what packages are installed. I did not perform the installs myself. I will update this thread when I get more details from my IT counterpart on how the system was setup.
This is used for a headless(no monitor, no keyboard) system running some custom applications.
Here are two problems.
1. If I plug into an ethernet network after I boot, the network never connects. I need to reboot with the network connected in order to get an IP. What is the service to "auto connect" to a network?
2. I have a network printer configured on lpd called myprinter. If I am connected to the network when I boot, I can print to this printer just fine using:
Code:
However, If I boot disconnected from the network and print to myprinter, the jobs obviously cannot print. They get spooled. Using 'lpstat -t' I can see that the spooled print jobs are assigned a job number and that myprinter is trying to connect. I shutdown, reconnect my ethernet network and boot up. All my printer configuration is blown away.
/etc/cups/printers.conf has been wiped out to look like this:
Code:
My 'good' printer configuration is copied to printers.conf.O
To recover from this, I need to stop cups, copy printers.conf.O to printers.conf, restart cups, and re-setup my network printer.
So, What causes my printers to get wiped out? I've repeated this on 4 systems with the same setup.

I am a Windows refugee who discovered Ubuntu as a way to save my files from my virus-ravaged computer. Had no installation discs for Windows, so when I had to wipe my hard drive and start over, I decided to give Ubuntu a try. I've had mixed success, but that's another post...
Right now, the problem is that I installed 10.10 two weeks ago and was able to connect to the Internet with no problems - until yesterday. Suddenly, our wireless network (the only one in the vicinity) does not come up as available in Network Manager. In fact, the entire wireless option disappeared. I know there are many posts and threads on here about this, but weeding through them trying to find an answer is more frustrating than actually dealing with the problem. I know the router works because I can post on this forum from the Macbook. I really like Ubuntu and would like to keep using it, but not being able to connect to the Internet now on top of the other issues I've had is making me doubt I want to continue down this Linux road.
P.S. When I attempted an analysis through System Testing, it said something about there being no proprietary drivers?
