Networking :: FC11 - DNS Stopped Working By Itself?

Nov 11, 2010

I switched my FC11 system off yesterday. Turning it on this morning, NO domain names can be resolved anymore.I can ping IP adresses directly, and even get to them in FireFox if I type the IP address. However, typing any domain name at all fails. I cannot ping or SSH to any domain name, but as soon as I enter an IP, it works. I can ping the DNS server by IP that is set in my /etc/resolv.confI checked on an XP system using the same DNS server set in /etc/resolv.conf (which can also be pinged on IP from my FC11 system), on the same connection from the same ISP, and it works.E. g. without touching anything at all (and all updates are turned off) my FC11 system has stopped resolving domain names.I'm running 32bit FC11. The system has been working fine for more than 2 years.So it has spontaneously stopped doing DNS when I enter a domain name. Where can I start looking?

Fedora Networking :: Wireless Suddenly Stopped Working - FC11?

Sep 23, 2009

A few days ago (september 7) my wireless suddenly stopped working. I am using FC11, and have an Atheros AR5211 wireless card and have been using the ath5k driver with GNOME NetworkManager. Wireless networks are detected by NM perfectly fine. When I try to connect, the icon spins around those two dots, and one of them becomes green. If the network is wep protected, it asks for the password. After a while, it times out, regardless of the protection. I don't remember changing pretty much for the last two months, so I'm sort of surprised. I did download and install a kernal, along with an selinux-policy update.

If I run dmesg, relevant looking lines included:

ADDRCONF(NETDEV_UP): wlan0: link is not ready
and a long series of these at the end:
wlan0: direct probe to AP 00:0b:86:4f:8a:20 try 1
wlan0: direct probe to AP 00:0b:86:4f:8a:20 try 1

[code]....

Note: I previously posted this in "Laptops," but Networking seemed like a better place to do it.

Fedora Networking :: Wireless Stopped Working After Upgrade To FC11?

Jan 12, 2010

I have a Broadcom wireless card in my hp dv6500z laptop, I had it all working properly in FC9 thanks to bbfuller and his post on the subject. After I upgraded to FC11 I have been unable to get it to connect.

I can see my neighbor's sites and suppose I could see my own if the SSID was allowed to broadcast but I keep that turned off. I put in all of the setting, including the network security key, but it won't connect, then when I go back and look again, the security key is not even close to what I put in; it gets changed to a huge string of characters.

I redownloaded broadcom-wl-4.150.10.5.tar.bz2.tar and followed the instruction on the post once again but no luck, which, after I thought about it, was a waste of time because if I can see other's wireless, then the card must be working. I have tried using Network Manager and not using Network Manager and still no luck...

Ubuntu Networking :: Wireless Suddenly Stopped Working AND Rfkill Command Not Working

Jul 13, 2011

When originally installing 11.04 I had problems getting my Ralink 5390 wireless card to work.

Today my computer froze completely and I had to turn it off via the power switch. When I turned it back on, wireless was no longer recognized! My iPod can connect to the network just fine, so it must be an Ubuntu problem. There are no problems with my ethernet connection either.

I researched this and found several threads about blocking and unblocking wireless devices using the rfkill command. Well, unfortunately for me the rfkill command doesn't work. When I type sudo rfkill list or sudo rfkill unblock all, nothing happens; it just returns me to my bash prompt. I even tried uninstalling and reinstalling rfkill...nothing.

Ubuntu Networking :: Wired Networking Stopped Working

Nov 6, 2010

Wired and wireless networking have been working flawlessly for years on my HP Compaq 6710b laptop. Several weeks ago, after an automatic update via the update manager, my wired network stopped working. I did not notice it directly, since my wireless connection took it over. I only noticed it when I had to work in an office where I didn't know the wireless password.Since then, I have been trying several things and searched several forums. It is hard to find any troubleshooting information about wired networking, as most of the problems seem to occur with wireless.

I did verify that there is no hardware problem. My laptop is dual boot and when I boot the other operating system, the wired network works without problems (as does the wireless.)My Ubuntu version is Ubuntu 10.04.1 LTS. My kernel version is 2.6.32-25-generic i686. I hope anybody can help me getting my wired network working again.

Fedora Networking :: Wireless Stopped Working In 12

Mar 18, 2010

I am having problem with wireless networking my fedora 12 since i opened network manager yesterday. But to my notice i haven't done any changes. But still i am not able find any reason for the wireless network not to work. When i try to restart the network servies it gives the following msg.

Quote:

Bringing up interface eth0:

This version of ISC DHCP is based on the release available on ftp.isc.org. Features have been added and other changes have been made to the base software release in order to make it work better with this distribution.

Please report for this software via the Red Hat Bugzilla site: [url]

Did i do something wrong with the network manager or did something go wrong with fedora.

Fedora Networking :: Cnetworkmanager Stopped Working In F15

Jul 22, 2011

I have been using the commandline for network manager cnetworkmanager in Fedora 14 without any problem. For the most part I used it to restart my vpn connection like so:

Code:
cnetworkmanager --activate-connection=user,'AAABBBCCC',eth0,& this was in a script that I put in the /etc/NetworkManager/dispatcher.d/ folder so it would start automatically whenever the vpn disconnected.

Last night, I had an epiphany and upgraded to Fedora 15, which seems to be working fine for me after updating a few programs including cnetworkmanager

At one point I realized that my neat little script wasn't working anymore though, so I checked out what happens at the commandline when I type the above command in:

Code:
[captainralf@Cap ~]$ cnetworkmanager --activate-connection=user,'AAABBBCCC',eth0,&
[1] 30884
[captainralf@Cap ~]$ Traceback (most recent call last):
File "/usr/bin/cnetworkmanager", line 319, in <module>

Ubuntu Networking :: Wireless Has Stopped Working?

Feb 25, 2010

pulled the wireless USB adapter out of the back of my laptop when I was using it. I plugged it back in and it can see my wireless network, but it can't connect. Everytime it tries, it just shows the connecting icon on the top bar for a few minutes and then says that the network has been disconnected.

I've tried uninstalling and reinstalling the USB adaptor, but nothing I've done seems able to fix the issue. Anyone know how to fix this?

The USB adaptor I'm using is a Trendnet TEW-424UB

Ubuntu Networking :: Wlan Has Stopped Working?

Jun 30, 2010

I have a Thinkpad T400 notebook that dual boots windows 7 and Ubuntu 9.04. My wireless has worked both in windows and ubuntu for the past several months. However 2 days ago, the wireless in ubuntu stopped working. I think this may be a result of trying to set up a static eth0 connection between my laptop and an embedded board, but I dont see how messing with eth0 would stop the wlan from working.

Symptoms: When I left click on the network connections icon in the tray, all it lists under "Wireless networks" is "device not ready". Needless to say, there are no networks available to connect to. Also the wireless is working fine under windows.

Ubuntu Networking :: Sound Stopped Working

Aug 2, 2010

Last night I was trying to get my printer working, and when I rebooted, I lost networking and sound.I am currently booting on a live CD, and sound and networking are fine-- so it can't be a hardware issue (obviously). I must have inadvertently broken something, but I can't figure it out.I have tried restarting networking, but it doesn't respond-- it says stop/waiting or something like that.I can't access the sound preferences-- it says waiting for sound to respond (or something like that).

When I reboot, sometimes I see a terminal window with the same line scrolling very, very quickly-- something about waiting for USB. Additionally, the system is very slow to respond-- clicking a menu item can take a long time for it to appear, etc.What could have occurred, and how might I troubleshoot it?

Ubuntu Networking :: Wireless Stopped Working On 10.04?

Aug 4, 2010

Just recently the wireless stopped working on Ubuntu 10.04. The machine is AcerOne AOA-150. I did notice recently the wireless would stop working, and I would need to either 1) reboot 2) switch the wireless off by moving the switch from left to right in front of the laptop.

However, this time nothing is working. I've provided some detail and if more information is needed, let me know.

LSPCI:
00:00.0 Host bridge: Intel Corporation Mobile 945GME Express Memory Controller Hub (rev 03)
00:02.0 VGA compatible controller: Intel Corporation Mobile 945GME Express Integrated Graphics Controller (rev 03)

Ubuntu Networking :: Samba Is Stopped Working

Jun 17, 2011

Been searching for hours and looked at several other threads but still can't figure this out. We have 4 folders being shared from a Ubuntu 10.4.2 LTS Server using Samba. A couple days ago two computers in the office lost access to these shares. The other computers in the office are fine. So far as I know nothing has changed on the server. I can putty into the server still but I can't map a drive or open a window through run (\server_nameetc).

I've also tried disabled iptables on the server and windows firewall on the the windows xp machines. Still no luck. What am I doing wrong? Like I said, so far as I know there have been no changes to the server whatsoever. One day it was working and the next it just stops.

Networking :: Network Connection Stopped Working ?

Nov 24, 2009

I have Debian installed a year ago, working perfectly until last week when network card connected to internet stopped to communicate. I did no change in configuration. It just stopped to work while I was reading an online web page. Network card connected to local network still works fine.

I thought it might be a NIC failure so I installed a new PCI NIC but no change, still no communication throught this NIC.

I verified/changed cable between NIC and the router, no luck. If I connect the same cable from router to a Windows PC, everything is OK. If I connect back to Debian machine, it does not work.

I tried connect this NIC with a different router with DHCP enabled, nothing, NIC will not communicate with DHCP server.

I tried to set static IP, no change.

Today I booted a Knoppix 6.2 and this NIC worked perfetly! It set up using DHCP, I could access the internet.

I booted machine as usual and the problem still persists of course.

This is information captured immediately after boot. The trouble NIC is eth0 after boot finishes.

All this was captured with eth0 connect to a router with DHCP enabled. There is no DHCP entry in syslog related to eth0. Reinstall is the very last option.

Networking :: Network Cable Just Stopped Working

Dec 14, 2008

I have a laptop, and the wireless and cable worked fine for a while, but one day, for some odd reason, the wireless and network cable just stopped working. I'd connect to the web, and I would get output using "ifconfig" and the GUI wireless signal. When I hook up the wire, it detects it. However, no matter what I can't load any web pages. The wire does work in another house, and my windows partition utilizes these devices well. Any ideas?Additionally, I am able to log into my wireless router and change configurations, but that's about it :/.

Networking :: VNC To Ubuntu 10.10 Suddenly Stopped Working?

Oct 13, 2010

I've started to set up a server at my house, where I eventually want to run it headless, and I can just VNC in from my other Desktop. I installed Ubuntu 10.10, setup remote desktop on the server, and from there was able to do any work remotely. That was nice. I turn the computer off at night, and the next day when I was going to work on it, I cannot VNC in anymore. One day passed, and now every time I try to use VNC it comes up with "Failed to connect to server" I also set a static IP address on the server too, so I know the address isn't changing every so often.

The card is the Intel Pro 2200BG. Please let me know what information is needed to diagnose and correct this issue. I am relatively new to Linux (Currently using F10) and trying to learn.This is the iwconfig from my cisco card. The Intel card was working fine yesterday. but now doesn;t even show up.

Fedora Networking :: WLAN Controller Has Stopped Working

Aug 1, 2009

I have a Dell XPS M1330. I installed Fedora 10 on a separate partition and left Vista on the first. It was working just fine and for some reason all of the sudden it is not recognizing the Wireless controller. Vista is still working fine although I did get a couple of "WLAN controller has stopped working" errors. I suspect I may have a physical problem with the controller but I'm confused as to why Vista is still using it but Linux is not. The actual physicall "WIFI" light on the laptop does not even illuminate when I boot Linux. No wireless networks appear in the network list under Linux. Particularly since it WAS working fine for months...

Fedora Networking :: LAN Stopped Working Through Wireless Router

Sep 17, 2009

I have a wireless router at home, but I usually have my laptop connected to it through an ethernet cable. It had always worked with no problems until some time last week when the wired network stopped working (but the wireless still works with no problem). At first I thought that it was some update, but no. My laptop works ok with the wired network at my office, and I also tried a different laptop at home and it didn't work. It's not the cable either, I tried a different one. I haven't changed any settings in my router.So I really don't know what's going on. I just find it weird that the router's wired networking suddenly stops working but the wireless still works fine...

Fedora Networking :: Wireless Card Stopped Working?

Jan 9, 2010

I have a relatively new F12 install (one week old) on which I got my wireless Broadcom card working using kmod-wl-PAE. It was a very easy process - not really a process just yum install kmod-wl-PAE.

After a few updates, I notice that the wireless card stopped working. I assumed maybe there was an update that conflicted, so I did a reinstall of kmod-wl-PAE and it worked again immediately.

Then I started installing compiz-fusion. Immediately after, wireless is broken again. So I yum erase kmod-wl-PAE and then yum install kmod-wl-PAE and it works again.

Now, only slightly later that same day, wireless stops working more or less randomly and I cannot get the reinstall of kmod-wl-PAE to fix it. So I uninstall, disable compiz-fusion, shut down, and restart the computer to try again. My thought is that maybe along the way my autostart compiz or something about compiz is causing the wireless not to configure properly. When I restart, wireless is working. Without kmod-wl-PAE installed:

yum info kmod-wl-PaE
Loaded plugins: presto, refresh-packagekit
Available Packages
Name : kmod-wl-PAE
Arch : i686

[Code].....

One, how is this even possible, and two, what is going on with the wireless working, not working, working, not working?

Fedora Networking :: VNC Server On Desktop 0 On 14 Stopped Working ?

Mar 9, 2011

For more than a year I was happily using my Fedora 11 remotely through VNC over ssh. I was using desktop 0 on port 5900 so people at the office can see what I am doing.

Yesterday I upgraded to Fedora 12, then 13 and then 14. I installed all updates of F14. All went well until I came to use this server from home as usual. The server was not responding.

I brought up /etc/X11/xorg.conf from a backup tape because I discovered that it is there that screen 0 is set and not in /etc/sysconfig/vncservers and rebooted. No success!

At the command lsof | grep LISTEN, I could not see a listener on port 5900

I activated screen 1 on port 5901 and I could log in OK and with lsof I could see listeners for ports 5901 and 6001 but I need screen 0!

During the day I tried many things including removing the vncserver packages with yum and re-installing them, removing the .vnc folder in the user home folder and starting from scratch. The server is still refusing connection!
