Debian :: Dns Resolving Stops To Work On My Machine ?
Oct 18, 2010
I have some strange problem with dns resolving. I am working on computer and suddenly, out of nowhere dns resolving stops to work on my machine. Sometimes networking restart solves problem, sometimes not. It happens randomly two-three times in a week, and at random time. Network in virtual machine on same computer works perfectly even if dns resolving stops on host.
I have tried everything but I can't find what causes it. How can I troubleshoot to find out what causes problem? Ten minutes ago it happened again and I have solved problem with networking restart.

I was wondering if Debian Net install would work on a Dell machine. Because when I installed Windows on it I had actually go online with my other computer to find the damn dell drivers. So just wondering if Debian would detect the dell devices and actually have drivers for it.Yes, I realize it's probably a completely stupid question.

I'm having trouble getting my debian box to find my windows box. This should be possible using netbios names.
The debian box is a newly installed minimal (nothing but base) release, to which I've added samba (using apt-get).
The windows box can see the debuan box just fine. Attempting to ping it by name results with:
Pinging debbox [192.168.1.100] with 32 bytes of data: ...
But going back the other way, the debian box can't see the windows box.
ping: unknown host winbox
I'm pretty happy that the windows box is behaving itself as there are no problems getting it to interact with other windows machines on the network.
Looking on google, the suggestion is to modify the host line in /etc/nsswitch.conf to include wins: hosts: files dns [b]wins[/b]
This worked on other linux machines in the past but not this time.
So my guess it that I've got SAMBA mis-configured or I'm missing a package.

So I am trying to do a Ruby on Rails install on a Debian OS. It is proving most difficult. There isn't much help from Google since RubyGems is supposed to resolve dependencies for you, so you can just type "gem install rails" and it will install everything you need. But as it turns out, RubyGems doesn't want do. It keeps getting stuck on either the "rack" or "rake" dependencies saying it needs to either be installed or updated when it is there and has a new enough of a version. I even tried this as root and it didn't work.

I have just installed Ubuntu on a machine that has an ATI Radeon 3450 video card installed. If I boot the machine into recovery mode and then select 'normal boot' at the pause I get to a fully functional desktop that is using the fglrx driver. Compiz is happy and my graphics look great. If I boot normally and just let the machine do its own thing I get just past the 'select' screen and the machine stops. There is no further disk activity and the monitor goes into standby mode. I can't see anything relevant in any of the log files.

My machine will not shutdown - It goes through the motions, it closes everything the green suse screen appears and the progress bar goes to the end. Then it flashes the keyboard lights and spins the disk down and then stops with the green splash screen - I have to press the power button to turn off.

I just installed a dual boot XP/Debian 5.0.4 setup on my Dell 5100 laptop. I now have constant problems with "resolving host" when using Debian. The connection when using a browser or downloading is noticeably slower than when using Windows or my Ubuntu install on my desktop. Also, whenever using the Debian install on my laptop, both it and my desktop, which both connect through the same Linksys router, constantly show "resolving host" (Chrome browser) until it just timeouts. Rebooting the DSL modem sometimes fixes it for a while (although it's still slow even then), but it eventually happens again. Turn off the laptop/switch to the XP OS on it, and the problems disappear on both the laptop and desktop. Is this a known problem for Debian 5.0.4?

I have a really weird one. This may be a putty issue, or it may be a config issue in Ubuntu. I've no idea who to blame. I have four machines involved in my little issue that has me scratching my head on where to even BEGIN to diagnose what is going on. The computer I'm attempting to connect to (For identification purposes, I'll call it the main machine) is running a relatively new install of KUbuntu 10.04, stock install of openssh daemon. ufw is disabled, firewalls are off, etc, and I can prove that later.
The machine acting odd is a Win XP 32 bit running Putty. Haven't had a problem until this reload of the previously mentioned machine. A Work machine that is running RedHad of some flavour. A Virtual Machine running a headless setup of Ubunto 8.04. Now that the introductions are over, here is a quick map of the machines that can successfully connect with. My major problem is that I cannot get SSH (And ONLY SSH) to work between the XP machine and the main machine.
Work -> Main = Works
Work -> VM = Works
XP -> VM = Works
XP -> Main = Fails
XP -> VM -> Main = Works
Main -> Main = Works (IE: "ssh localhost")
VM -> Main = Works
When I try to get the XP machine to connect to the Main machine, I get an error with Putty saying:
"Server sent disconnect message
type 2(protocol error):
baad service request ssh-connection"
I've changed Putty to try using SSH Protocol 1 only, but it says the protocol isn't installed on the Main machine, which is true. I've tried setting just 1, and it gives me the error, and I've tried setting it to "2 only" and it again comes up with the error. I went into /var/log as root on the Main machine, and did a "tail -n0 -f *" and then tried to connect, but nothing relevant shows up.
As for the proof that the firewall is disabled, three of the machines are working with Synergy, I am able to swap between all three of the machines without a problem, I can get to WebAdmin from the XP machine to the Main machine, and I can open a Samba share from the XP machine to the Main machine without a problem. This sounds like a protocol issue, but I can't see anything in WebAdmin that'll put me in the right direction.

Under 11.3 32bit I could play my favorite station with vlc, but not with any other audio player. Under 11.4 32bit it stops playing after about a minute without any error reporting. Sometimes it starts up again, speeded up, then stops. Here's how I invoke it from the command line...
"vlc http://www.garnierstreamingmedia.com/asx/streamerswitch.asp?stream=205"
No other audio player works with it now and only vlc worked before. It's not my Internet connection because other stations play normally.

I've been trying to get some help with a problem I'm having in Deluge. I started on the Deluge forums but am not really getting much help, so I figured I'd post here and see if maybe someone has an idea of what's going on. code...
I'm running Deluged and using the Web Interface. I start the computer up and download the first Torrent (or set of Torrents) fine. After they're done, if I add any more Torrents then it won't transfer them at all. It shows no Seeders. Peers go up and down like they're trying to connect but losing connection. 20-45 minutes later, it starts downloading. Until I updated to the PPA version, it would download slowly but after updating now it downloads full speed. If I kill Deluged (Rather than waiting a possible 45+ min for it to start) then it starts downloading at full speed right away.

I'm know very little about Linux but decided to set up a machine running Drupal CMS on a Debian machine and it won't go. The folks at Drupal have tried to help but it seems the Debian OS won't do it's PHP thing for Drupal.
That means i'll have to start at the START I guess.
how to become a master of Linux if one is starting from ABC (I can add and subtract, that's what it feels like)

I set up a virtual bridge for a virtual machine (qemu-kvm) using a qemutap interface:
Code:
# brctl show
bridge2 8000.0022648a3dcc no eth5
qemutap2
I can ping and ssh to the server ...
Then I try to copy (scp) a file (2.8 M) to the server and, near the end, the copy stops and the server stops responding to ping and is not able to ping nothing except itself.
"ifconfig down ; ifconfig up" and the server is on line again.

I use my debian machine for masquerading, packet filtering anilar for a tiny network.It runs the latest debian testing.Every now and then (i am talking about weeks) the connection to my internet stops working.ifdown eth0; ifup eth0 brings it back.The other interface (eth1) is never effected.The odd thing is, there are no warnings, no messages .. nothing.I cant find any entry. Nothing in the logs, nothing in dmsg and no kernel panic.The only way to find out when it might have been happened is to search in several daemons log files,to find out when their first error connecting to the internet occurred.I ran memtest without any results.The nic is e1000 compatible.

I have a Lenovo Thinkpad R500, and recently I recently upgraded it with a Crucial SSD as well as 8 GB of DDR3, as I had a blank SSD installed, I decided to switch from Mint to Debian and see how I like it. I'm using Debian 8 with the MATE desktop and so far it's been quite a pleasure to use, besides one small thing.
Every 5 to 10 minutes, DNS resolution stops working completely. I can ping IP addresses as well as connect to websites by IP address just fine, however I cannot resolve hostnames. The problem exists regardless of whether I'm connected to my router via a wired or wireless connection. It is not occurring on any other computer in my house and didn't exist on my old Mint installation. If I disconnect from my home network by either unplugging the Ethernet cable or flicking the WIFI switch on my laptop, and then reconnecting, I can resolve hostnames again, albeit only for another 5-10 minutes, when DNS stops working again.
I was originally using DHCP and my ISP's DNS servers, but switched to my laptop using a static IP address and Google's DNS Servers at 8.8.8.8 and 8.8.4.4, the problem persisted after this change.

I want to know what's going on here. I'm used to find files in my Debian box usingfind / -type f -print0 | xargs -0 grep -l "foo"but it's been a while since this type of search simply stops at the /proc/kcore directory. I know it has something to do with memory. Is this normal?

I found that in many occasions ice weasel browser stops functioning (not responding) and the only way out is by killing the process.secondly, the process ID is actually firefox!! and no ice weasel process, cause ice weasel is just another name to firefox; and this stopped me from installing firefox.Unfortunately, when I used Konqueror which comes with every linux distro, it gave the same problem.

I have a USB mouse which randomly stop in Debian Jessie. It starts again if I disconnect and connect it again.
It can take a couple of hours or just a couple of minutes. The only thing I've been able to find is that it stops more often when I'm scrolling.
I have tried different mice with the same result. I recently migrated from Ubuntu where I did not have this problem so I doubt there is a hardware error.
I can see the syslog updating every time I connect the mouse but I can't see anything when it stops

I have a Dell Latitude D505. I installed Squeeze on 12 November 2011 from the weekly DVD. I install updates every day, when available.
My kernel: 2.6.32-5-686 #1 SMP Thu Nov 25 18:43:34 UTC 2010 i686 GNU/Linux
Everything is working fine except the button that is pressed when I close my lid. Hibernate works, Suspend works, blank screen works. user is member of the group "powerdev". I really thought thread "closing-laptop-lid-renders-computer-unusable-786822" would bring me a solution. When I close my lid my screens turns black with my mouse cursor on it. Connections with ssh are broken. Keyboard is dead, mouse pad too. It looks like it never start any software it just hangs immediately. I cant find anything in my logs.

I am having a problem which I am having a hard time finding out about. To start I am running Debian 8.0 on a laptop through an external Seagate 2TB HDD that I connect via USB 3.0. My problem, basically, is when ever I use Linux for an extended period, for what ever reason, some of my icons disappear and my terminal breaks. More specifically, say I were to try to shut down the computer at the time of the problem the icons and text telling me which option is which, in xfce4, are gone. Then if I click on the would be shut down button it just goes to a black screen with a white underscore and hangs there. This symptom is probably due to the fact that commands in the linux terminal stop working. As in, if I were to type ls it tells me there is no command (something like that) and tells me some folder directory that I think is where bash is located. I wish I could be more specific with some of these details.
Anyway the only way for me to "fix" it is to just do a hard shut down, then upon reboot it clears the orphaned nodes. Also, before, when I installed linux several weeks before I never noticed this issue, if it was ever present. However, now that I have seen it, I have since tried re-installs of debian to no avail. I have a feeling it could be the external hard drive, but that notion is not based on any evidence.

Have a little experience with backtrack 4, which is a Ubuntu distro. I'm changing to Lenny due to hardware limitations on my laptop, an older Dell inspiron 7000.
Here's the specs :
400 MHZ,
120 G HDD parted as C: = 20G (has bad sectors, left blank) and D: = 20G Windows part
128 Mb low density RAM
ATI Rage Mobility ( not sure of video RAM, I think 8 Mb)
Now I liked running BT and liked the linux work, so when the BT install went south I started to look for another linux distro I can run, the BT tools I use are linux after all. Here's where I hit my stump. I decided to go with the Lenny distro, it already has some of the tools I need, but the first time I installed I had the HDD like this 20G, 20G, 20G,20G, 17.??G. I had windows installed on C: (of course, no problems, yet)
After I installed lenny to D: via an iso I downloaded, the Debian GNU/Linux 5.0.6 "Lenny" - Official i386 xfce+lxde-CD Binary-1, BTW first install was from booting from the disk. After reparting, format, etc. of the install, GRUB boot loader detects my D: Windows, great. Reboot to GRUB boot menu, select ddebian, and it loads...cool, until I realize I don't have synaptic, the tools, and apt isn't going to work unless I can load the linux driver from the cdrom...which I can't find.
Reboot...windows, internet for answers I'm thinkin. GRUB loads fine, select windows and get the following error message "Windows can't start because of hardware configuration problems. Could not read from selected boot disk, check boot path and hardware. Check configuration manual for disk configuration."
It took three days to get Windows reinstalled, and a LL format (zerowrite the drive) but during the process I discovered a possible hdw issue...bad sectors on the C: hdd. Solution: C: 20G = unused, D: = Windows xp. Worked great. No more windows issues, so try it again. This time I used the disks installer from windows. Everything started great, boot menuselected debian, install-graphic, but this time I let the part manager create a drive, 20G from the free space an it appropriately made it's swapfile...when lenny booted it was good, but still no synaptic, cd/rom, couldn't browse the computer.
Reboot to windows to get instructions from someone that really knows what's going on...no windows. exactly same message as before. I was able to boot into debian okay, but couldn't find any drives, utilities, wasn't very much, but I needed my windows and the internet to get lessons. I am familiar with the terminal console and KDE. Can use apt for updating, but prefer using the synaptic. Why does my windows keep disappearing? If I can solve the dual boot issue I can learn the system casually. Right now my config is: C: = 20G, nothing here, still haven't run a scandisk either...next on todo list. D: = 20G Windows install...what I'm using now. I'm not going to attempt to reinstall debian until I receive a efinate answer to the dissappearing config, or boot capacity. Oh, yeah, Did try a fdisk/mbr and fix. this didn't bring it back either.

Running Debian 8, thunar 1.6.3. Randomly thunar stops redrawing and stops responding to mouse and keyboard input.
This is annoying because I usually have a handful of tabs open and I "lose my place."
