Networking :: Sudden Network Troubles On Debian With No Apparent Reason?
Apr 7, 2011
I just want to see if anyone else is having problems connecting to networks, wifi or wired. For some reason, I can see both wired and wireless networks available but when I try to connect, it times out. I updated a couple of days ago and suddenly started having problems today. Anyone else having the same problem?I have only tried the router and repeater I have to connect to. My other computers are working just fine. One is actually running as a Debian server with no GUI (which I do not update as often). The other is a Mac.

Network stopped working about a month ago. I installed ubuntu again, and network worked fine, and I turned off updates to keep things stable. Now network stopped working again. No changes had been made to it.I put in the ubuntu install cd, and network works fine off of it. I did not reinstall again. ifconfig shows eth0 with correct ip address, but 0 RX/TX packets.
Cant ping anything from it, and cant ping to it from other computers.I'd really rather not reinstall yet again, any ideas on how I should go about diagnosing this problem?Ubuntu 2.6.35-28-generic-pae #49-Ubuntu SMP Tue Mar 1 14:58:06 UTC 2011 i686 GNU/Linux

I was struggling frantically this morning for about 5 minutes after I booted up my computer, and wondering why it couldn't connect to the internet. After I figured out that the automatic wired network "Auto eth0" was gone from the network manager, it was easy to manually add it back. But why did it disappear in the first place?

Ive been searching half the internet for a solution for a strange problem im having with a server (CentOS 5.2 Final). For no apparent reason, the server will just be powered off.I've looked in the dmesg log and /var/log/messages file, but that doesnt show anything, except the "syslogd 1.4.1: restart." message after booting it up again, and hours in advance of the crash a "suhosin" alert message.

I have just installed (after a series of crashes during the install) Fedora 15. I also have Ubuntu Natty installed and use it primarily but I wanted to reach out and try new distros.I've wanted to try Fedora and finally got enough nerve to try. Installing it crashed for no apparent reason several times.ehow it installed and booted right to Fedora.However, when finally figuring out how to run the updates, I began to have the same problem.(Someone elsewhere suggested trying to update through command line--which I did finally though I had a few crashes doing this).
Now I am logging in and then it will just inadvertently crash. I could be in firefox, or using terminal, etc. There doesn't seem to be much rhyme or reason to why this is happening and I feel frustrated. I really want to test out Fedora (it looks so nice!) but can't manage to stay afloat more than a few minutes. I might also mention that this does not happen in Ubuntu at all so I can't account for the issues. I have much to learn but I feel a bit intimidated by Fedora because it's so new to me.

I woke up this morning to a message saying I have low disk space in /home. My /home partition is 150 GB, but I had only 4 kB left. I promptly rebooted, which helped, but I still only have 40 GB available. Now, I use only 26 GB, so where the rest is, I don't know. In the disk usage analyzer, a lot of the space was not accounted for, as shown in the image.
Here is the output from df -h and du
simen@simen-laptop:~$ df -h

/dev/sda5 55G 8.0G 45G 16% /

I checked out .gvfs and it's just a CD I have playing. I really don't know what's going on.

I've been an Ubuntu 10.04 64 bit user for one year. My Ubuntu distro is installed on an ext2 file system. Occasionally, I experience disk checks during boot without any system freeze or power loss.Sometimes, once reboot, the system works fine but Evolution Mail requests a new account, as if it was used for the very first time.Does anyone know how to fix this problem?

At first I was connecting to the internet via WiFi on my home network, and all of the sudden I couldn't connect to my wireless network anymore. The strange part was that I couldn't see my wireless network connection. But when I go to hidden wireless network its there, yet I still cannot connect.Im using the Ethernet core for now and it works fine.
Code:
fasttiger@Beast:~$ iwconfig
lo no wireless extensions.

I'm trying to set up a mini grid of linux boxes, but am quite new to setting linux up.I've installed fedora 13 on one and would like to be able to SSH in to it. All boxes are within a university network (under a proxy if that makes any difference?).I can mount a shared disc easily enough, and SSH out to other computers (that I didn't set up myself),I've tried following a few threads, temporarily taking down firewalls, disabling SELinux, messing around with iptables but can't seem to manage it.

When I start the laptop, booting squeeze, after the screen printed"waiting for /dev to be fully populated... conflict with acpi region smbi..." (and maybe some other msg followed) the laptop will suddenly power off and automatic restart, after several times restart, I may have good luck to log into the squeeze KDE interface. The problem also occur when I choose booting in recovery mode How can I fix this annoying problem, or where can I check the fail booting log before the restart log overwrite it?

I was just doing the normal stuff, working with my raid-setup. Then I needed to reboot. I did that, and then my internet sharing just stopped working?I remember I just did aapt-get update && apt-get upgrade && apt-get dist-upgrade && apt-get autoremove && apt-get cleanbefore booting, and I just dont rembember if that said anyting crucial, but I really dont think so. Anyways, my LAN i working, all my LAN computers speak with each others, and I have internet (...) on the server. But my sharing just doesnt work. This is how I share my internet:
ifconfig eth1 192.168.0.1
echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -t nat -A POSTROUTING -s 192.168.0.0/24 -o eth0 -j SNAT --to myip

For some reason my wireless connection has gotten weaker all of a sudden(from 89% to 65%) and I haven't left the place where I am with the computer. It just got weaker all of a sudden.

For most of today I had my internet connection dropping out on me intermittently. I assumed it was a provider issue, as it has been unreliable in the past. After it dropped out for good, and I could not print through network, I realised it was not a provider issue. All the other computers in the house were connected, including another ubuntu box. Only the MacBook Pro 5,5 was not able to connect. The network manager indicated I was connected to the network, throughout the whole time.
A number of restarts with the kernel I normally use (2.6.31-19) including one in recovery mode, yielded no change, but a restart with the 2.6.31-20 kernel resulted in connectivity. Finally, perhaps by chance, wireless started to work again on the 2.6.31-19 kernel, after I once booted into the Mac OS, and then back into Karmic. How I might go about diagnosing, obviously in hindsight, what happened? I suppose I should look in the log files, but I have no idea where exactly, and what to look for.

I was connecting to the internet with no problems at all until two days ago. a while back I set my local IP to #.#.#.11, the internet failed.
Code:
I removed the added code from /etc/network/interfaces and the internet started up again, however the card retained the .11 IP address and has done through many installs... Don't know why or how, probably just a router DHCP setting not retiring the IP of machines.
That wasn't a problem as far as I know.
Ok, so I check a wired connected win7 pc and an ipconfig /all shows he's got the #.#.#.11 address. Checked a wireless win7 netbook and it got a #.#.#.24 address
Wireless key double checked and is correct.
I'm now on my WinXP partition (dual boot with the same ubuntu install that won't connect to the internet) it's getting the IP #.#.#.5 and is connecting with no trouble(albeit slow windows)
All machines are set to automatic configure, but obviously retain the same ip for a while.
I've tried
Code:
iwconfig show that the wireless card is indeed wlan0
Here's basic information
Code:
Wireless card on non-connecting machine: Belkin N+ wireless card, v2001, NDISWRAPPER
will this work?:
Code:
The problem is that if I try and connect to the router it does the "connecting rotating circle" and then just either has a message "disconnected from wireless" or asks me again and again for the WPA key, which is already correct.
LiveCD and fresh install both fail, used ndiswrapper and it's always worked fine before.
using Ubuntu 10.04
How I can get connected again? This is a desktop, a wired connection is just NOT possible.

I installed 11.04 last week. Everything was working brilliantly until I turned on my laptop today. Now my wireless internet is running soooo slow. Requests take like 5 seconds, then it loads the page for about 10 seconds. Last night it was running fast.Chrome/Chromium/Firefox all run super slow. I tried turning off wireless-N and using G instead, but that didn't help. My windows 7 desktop is not experiencing the same problems in Chrome, or Firefox. I'm not sure if it's updates that I installed yesterday that didn't take until I restarted today

I am running Linux Mint Isadora 9 and recently installed a wireless USB adapter. After installing RT3070 drivers for my RT2070 card I got everything working and life was good. Now, all of the sudden I am having a world of problems connecting to the internet. I can connect to my AP fine, but I cannot access the internet. If I attempt to ping my AP by IP address I get severe packet loss. I cannot ping my AP by url [URL] at all so Im guessing there are some DNS issues as well.
Code:

i was compiling and installing the new linux kernel for my debian box, i ran the commands
# make oldconfig
# make clean
# make DEB_PKGVERSION=custom.3.0 deb-pkg
# cd ..
# dpkg -i *.deb
i tried to install the new kernel which was made into debian packages ready to be installed and after i ran that last command this is what came up
dpkg: error processing linux-firmware-image_custom.3.0_amd64.deb (--install):
package architecture (amd64) does not match system (i386)
dpkg: error processing linux-headers-3.0.3_custom.3.0_amd64.deb (--install):
package architecture (amd64) does not match system (i386)
[Code]....
where do i make this work, my architecture is an amd64 but for some reason it's only going to install this kernel on a i386 system.

Since F12 I've big troubles with my left shift key.
I've Fedora running on 3 hosts. 2 desktops and 1 laptop. Only on one of the desktops I've these troubles.
If I press the left shift key sometimes shift gets locked. If it's locked, no key can unlock it. Not the left, not the right shift, nor any other key... and I tried them all meanwhile;-)
It's a real shift lock, not a caps lock. After a (random?) time it releases itself without any user interaction. Releasetime varies between 1 and many seconds.
So, only waiting helps. I already followed the wiki entries for debugging keyboard (input-dev) issues. Watching the output of evtest shows exactly the same output for the usual case and the lock case. They both look like this... code...

I'm trying to install OpenSuse 11.2 from iso image without burning it in a DVD.. because I don't have a CD or DVD drive.I'm using Windows Vista.firstly I mounted the dvd image .. but thought that was wrong because when rebooting instillation won't find the image.. is that true?so, I extracted it and I opened openSUSE11_2_ LOCAL.exe. and then reboot.. got two choices (Vista or install OpenSuse) and selected install OpenSuse but my screen went "out of range" !!

I was updating grub and for some reason the system hanged. Going to a tty did not solve any problems. At the end I had to do a hard reboot and came up with the following on the grub boot
reloc offset is out of segment Entering rescue mode grub rescue >
Googling for the above I landed on this page.
[URL]
While I'm going to try the later part, is there anything else I need to know about ?
Didn't have to do much, took the the Squeeze 6.10.a DVD, asked it to run into rescue mode and then did grub-install giving the MBR (hd0) as the place to be. Things worked nice after that.
Upon booting had to run
dpkg --configure -a
and it updated grub to 1.99-5 among other updates. Did not know that Squeeze had a rescue method as well (just like Ubuntu live CDs have). Now just have to wait for Debian to get Live CD/DVD as default

I use Sysv-rc-conf to turn on/off services. I initially turned off cups (I'm pretty sure it was on by default) using this method, but now I have turned it back on again, it won't start at boot. I have to start it manually each session. I've probably missed something but here goes anyway,

My hp does not want to start X for some reason. I have so many errors. I made an account to just see this problem be fixed. Now when I type "startx" I get back, "bash: /usr/bin/startx no such file in directory". I have to use GRUB due to the fact I forgot my login. Although, I do remember my password.
