Ubuntu Networking :: Resolve/general Connection Errors Under 11.04?

May 28, 2011

I have a Lenovo Thinkpad SL510, with a "Realtek RTL8188CE 802.11b/g/n WiFi Adapter (rev 01)" wireless adapter, on Ubuntu 11.04 x64. When I run updates, I get many resolve errors "Something wicked happened resolving us.archive.ubuntu.com," and other errors like that.Also, the internet connection runs incredibly slowly, and a lot of my downloads through firefox freeze and fail. I'm wondering if all of these problems are connected. Here are the contents of /etc/resolv.conf

Code:
domain gateway.2wire.net
search gateway.2wire.net

General :: How Yum / Apt-Get Resolve Dependency Errors

Mar 22, 2011

Say if I want to install openssh in traditional way with ./configure then make and make install which works fine in Fedora but not in Ubuntu as it gives error for a Mailer program when ran ./configure, as sendmail is by default installed in Fedora but not in Ubuntu. What I need to know is how yum/apt-get resolve this dependency problem? Is there any file in the OS where it's listed all the dependencies along with the package names like in Redhat installation CD there are some XML files where it lists all the packages along with their dependencies.

Networking :: 'Unable To Resolve Host Address' Errors With Newer Distributions

Mar 10, 2010

I'm trying to troubleshoot some strange networking problems. The pattern seems to be that only newer distributions are affected. CentOS 5.4 and Ubuntu 8.04 work fine out-of-the-box. But Arch, Sidux, AntiX, Fedora, etc. show the same pattern of errors.Certain websites cannot be found unless I disable ipv6 in Firefox. And certain addresses cannot be resolved using various terminal commands (wget, apt-get, yum, etc.). What I would ideally like is a permanent solution, perhaps changing some settings on my router, so that I don't have to deal with this each time I test-drive a new distro. I have a hunch the issue has something to do with my DSL provider (Fairpoint) filing for bankruptcy.

One more piece of information that may or may not be relevant: I recently switched a website from one hosting company to another. I noticed there was a delay of several days where I saw the old version at the old host, but viewing the site at a friend's house or the coffee shop showed the new site on the new host. This leads me to suspect DNS issues perhaps, but this is not an area of expertise.

Ubuntu Networking :: Wired Connection Keeps Dropping Out / Resolve It?

May 13, 2010

Two weeks ago I decided to ditch my XP install completely and switch to Ubuntu 10.04. So far so good, and I'm very happy with my decision. However, about 3 days ago, my wired connection started playing up. It keeps dropping out every 2 hours or so between 13.00 and 04.00. After dropping out, it immediately reconnects again (at least when I use Automatically DCHP config). From 04.00 to 13.00 it is more or less stable.

I tried resolving by reserving an IP in the DCHP Client Table in my router (linksys WRT120N). Additionally, I told the Network Manager to use the Manual configuration. Unfortunately these changes didn't help and the problems stay the same......

The daemon.log shows the following information code...

Networking :: Received Data - RX - Errors And Very Slow Connection

Jun 22, 2010

I have a Webserver (Co-Location) and all runs fine ... since last week. Now there are a lot of RX-ERR shown in netstat and ifconfig. And when I try to upload a external website direct on the server for example via wget, it is very very slow and hangs very often.

RX packets:2919694 errors:990386 dropped:0 overruns:0 frame:596420
TX packets:4231423 errors:0 dropped:0 overruns:0 carrier:0

I have analyse the network but I was not able to find a problem. My hoster has checked the network and all looks fine. For example my hoster has plugged-in a pc in the same switch ... and was able to do wget (load external data, like websites) in normal speed.

Since last week my websites were delivered slower as before, too. It seemed there is a network-problem ... but how can I find it?

Actually I can install moduls ... but the server needs hours. So, if you knows a good command-line tool to analyse the network.

General :: Connection - Randomly Been Getting Samba Errors

Apr 26, 2011

We have a Debian Linux Server with Samba setup. It connects to our lab computers each night to pull new data over. It's worked great for several years. Over the last month or two it has randomly been getting Samba errors (13663, 13668, 13673, 13683, 13693, etc). I don't know if those numbers mean anything because they are all different. Usually after rebooting it would be fixed, but it seems to be getting more frequent.

Ubuntu Installation :: Boot Errors / Resolve This?

Aug 21, 2011

I've had a lot of success over the past year with Ubuntu 10.4; however, recently I've been experiencing nothing but problems. It all started with an upgrade a month ago that caused me to experience a boot error. Now every time I re-install the system, I will have a random boot error. I have been trying to install the system on a friend's computer and getting the same thing. I've tried a different download and burned different discs, but I am still experiencing problems with the system having a boot error. Sometimes it is immediate after installation and other times it might boot fine for a day or two and then suddenly it will no longer boot. Is there some kind of bug with 10.4 now? I never, never had this hard of a time with Ubuntu. I've installed it on several computers for myself and other people.

Ubuntu Servers :: Eth0 Disappeared / No Network Connection - Resolve That?

Aug 8, 2010

After rebooting, I found that the server couldn't see the network. The machine has dual gigabit ethernet (eth0 and eth1). eth0 is connected to the internet, but disappeared. ifconfig used to show eth0, eth1, and lo, but now only shows eth1 and lo. If I boot into rescue mode I can get internet and ifconfig returns eth0 and lo. Any ideas on how to fix this?
I apologize in advance if I ask any noob questions. I'm not a very experienced Linux user.

Debian :: WiFi Connection Cause Squeeze To Crash / Resolve This?

Aug 21, 2010

I'm using Debian-Squeeze, and the command "uname -a" results in "Linux debian 2.6.32-5-amd64 #1 SMP Sat Jul 24 01:47:24 UTC 2010 x86_64 GNU/Linux". The desktop environment is Gnome 2.30.2.

My problem is wireless connection causes the system to crash. Here is the detail: my university uses a WiFi service that we have to enter our ID and password in a certain web page in the browser to get access to the Internet, while the WiFi signal is automatically picked up. My laptop crashes each time I connecting to such wireless network. But back home, when connecting to my own WiFi, everything is all right.

As the only thing I can do when such crash happens is to press the power button to force the computer to shut down, I've gathered no more information till now.

Does anyone know what's wrong and how to fix it?

Ubuntu Servers :: Dropping Network Connection And Other Errors

Sep 11, 2010

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:

Code:

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.

OpenSUSE Install :: Unable To Upgrade To 11.4: Can't Resolve Host / Error Code: Connection Failed?

Apr 1, 2011

I'm currently running 11.3 and decided I'd try upgrading to 11.4 following the instructions here: SDB:System upgrade - openSUSEUnfortunately, my attempts are defeated at the point of trying to refresh the new repos; I get the following message (for the oss repo, in this case):

Download (curl) error for 'url':
Error code: Connection failed
Error message: Couldn't resolve host 'download.opensuse.org'

With 11.4 replaced by 11.3 in the repo url, it refreshes just fine. The only repository that works when I change 11.3 to 11.4 is the Packman repo. I'm not really sure why the connection fails for 11.4 but not 11.3!

Further info: I have an old router with no IPv6 support, but have IPv6 disabled system-wide. I can enter the url for the repositories into firefox and they come up just fine - it's only with zypper/YaST that I get the above error message.I also tried upgrading using the network CD but ran into the same sort of problem. In this case it may be because the CD installer doesn't disable IPv6. (I didn't want to download the DVD at my connection speed, and the KDE live CD is not listed as suitable for upgrade).

Software :: Vnc Server Used To Work Suddenly Stopped Working With Connection Refused Errors

Feb 22, 2011

I have a machine running with slackware64 13.1 and vnc servers is installed on it. It worked for months until yesterday, when I couldnt connect to the machine remotely.

I have 2 vnc "users" on this machine, root and "user". Each have their own desktop. Root has desktop :1 and user had desktop :2. Simple enough.

VNC servers is started via /etc/rc.d/rc.local with the command:

Code:

Code:

It worked flawlessly. I use the very same configuration on my home server, never had a glitch.

From the "distant" machine, I get this error when I try to connect:

Code:

Unable to connect to VNC server

What has changed so it no longer works? I assume its not a network problem since the machines are all located in my home network and there is no firewall or router in between them.

Ubuntu Networking :: Setting Up Bluetooth Connection Between Two Computers Throws Connection Refused (111)

Apr 3, 2011

I'm trying to create a PAN (Personal Area Network) using a laptop (Siragon ML-1040) and my desktop computer, but I get the Connection Refused (111) error.

Blueman doesn't detect any network service between the two computers unless I start PAND on one of them and then it detects the NAP service. That, only after I enable the NAP/Workgroup services on the Services submenu in Blueman. However, it doesn't work neither with the NM plugins or without them (dhclient and that other one I can't remember the name of).

Any clues over here? I'm using pand 4.91 and blueman.

Ubuntu Networking :: Could Not Resolve Host Name?

Apr 29, 2010

I'm having an issue where some of my machines hostnames are no longer able to be resolved after setting up a mythbuntu backend to allow netboot. Also it seems that which machines hostnames get resolved is not consistent. (ie sometimes one gets resolved and sometimes it doesn't) I suspect that it has something to do with the changes I made to "/etc/ltsp/dhcpd.conf" to get the netboot running.

I have a Verizon DSL modem/router as 192.168.1.1. Up until playing with the "/etc/ltsp/dhcpd.conf" I saw hostnames of all of my machines show up in its network map. Now, some of my machines still get network access but their hostnames are no longer resolved. What did I do wrong? Here is my dhcpd.conf file:

Code:
# Default LTSP dhcpd.conf config file.
authoritative;
subnet 192.168.1.0 netmask 255.255.255.0 {
range 192.168.1.2 192.168.1.250;

Ubuntu Networking :: 10.04 - Cannot Resolve Names Using DNS

Sep 16, 2010

A while ago I downloaded a VMWare VM for 7.10. I then upgraded it to 8.10 and it was working just fine. I just did the upgrade to 10.04 and I'm having problems with my networking. The really odd thing is that I can ping machines on my local network and out on the Internet by IP address but it will not resolve names using DNS.

I've got the network set up for DHCP. I also tried DHCP address only and manually entered my DNS server addresses but still no luck on resolving names with DNS. At the end of the day, I don't really care if I get this fixed or just get a new VMWare VM. (I can't create one because I only have the player.)
