Debian :: Debian Server Down In Middle Of Night / How To Diagnose This
May 30, 2011
I'm not really a beginner but i will post here, i think there is a simple issue here.
I set up a new cloud server (debain 6) at CloudSigma, it has a joomla site on it, prob gets about 2000 visitors a day
Yesterday i unleashed it on the world , it was all ok when i went to bed.
At about 5.20 or 5.30 it went down, i found this out from App First notification, shame i didnt see the email until this morning lol.
Anyway there is no logical explanation as to why this would happen, how to diagnose this.

i recently switched from slackware to debian because my laptop kept freezing up on slackware, and now it's doing the same on debian on slackware i would get this error in syslog: "hpet: compare register readback failed" at the exact time of lockup, which would leave me with a blinking capslock led indicator, and a completely frozen system (not even magic sysreq sequence would do anything) now on debian, same symptoms only there's nothing in syslog, and no blinking capslock led hardware is: i7 720q intel pm55 chipset nvidia gt 240m laptop model is lenovo ideapad y550p this will occur both in X and at the console i am using my own kernel as the default kernel doesn't support my ethernet adapter i have tried disabling hpet at boot, but there was no difference i have tried the patch posted here

I've got an LG CD/DVD player/writer in my desktop, and it's suddenly stopped working. No error messages at all, but it doesn't acknowledge any discs any more, whether they're CDs or DVDs or CDRWs or anything. How can I diagnose what's wrong? It's only 1.5 years old so I wouldn't expect it to be a hardware problem really, but I can't think of anything else. At first I thought I'd broken something with Squeeze, but I ran a live system from USB stick and it also can't read any discs at all. Also I tried a bootable DVD and couldn't get that to boot either, so I'm pretty confident it's not a software problem. It's always worked fine before and hasn't had any shocks or moves or anything (that I know of). The green light flashes when I close the drawer, just flashes a few times and then stops. There's nothing in /var/log/messages. Are there any tricks to figure out what might be wrong or is it looking like I need to buy a replacement drive?

I posted this over in the VirtualBox forums but was directed to the debian forums as it was the debian fork.VBoxManage and all virtualbox GUI elements are black with white text ("night mode" in other apps) with no borders or other useful Gui bits. Apparently the board image quota is reached (?) but you can see it here: URL...All the guests work, it's just this GUI issue.
Code: Select allii virtualbox               4.3.30-dfsg-1+deb8u1         amd64    x86 virtualization solution - base binaries
rc virtualbox-4.3             4.3.30-101610~Debian~wheezy     amd64    Oracle VM VirtualBox
ii virtualbox-dkms            4.3.30-dfsg-1+deb8u1         all     x86 virtualization solution - kernel module sources for dkms
ii virtualbox-qt             4.3.30-dfsg-1+deb8u1         amd64    x86 virtualization solution - Qt based user interface
vbox-install log on other board,I upgraded from Debian 7 stable to Debian 8 stable. I haven't used virtualbox in a long time, so maybe I somehow did this myself, but I'm not sure where that is if I did.
I couldn't find anything else in /var/log that would be useful. It's across all users. I checked the launch scripts /usr/bin/virtualbox, /usr/bin/ vbox manage, and /var/lib/virtualbox/*

the Squeeze uprgade I also lost the middle mouse functionaly of my Logitech Marble Mouse. I do not remember how I set it up to be honest. I am not sure if it was by default middle was mouse was "pressing 2 buttons on eachside at the same time" or I did set up manually using Xmod or similar tool. I might have even set up in the hal settings. The reason I do not remember exactly is that I used multiple tuts and places to set this up long time ago and now that the functionality is gone I am kind of confused about how to go ahead about it.

I initially installed Debian with the Gnome desktop. I recently installed the KDE desktop enviro to try it out, but when I log-in to it, a big grey box with a white horizontal volume level bar in it shows up in the middle of the screen, and you can't get rid of it. It is always on top, on top of any other open app or window. Trying to quit Kmix from the panel bar doesn't help, it doesn't even get rid of Kmix, it immediately reloads and pops back up in the bottom panel bar. Also, you can't adjust the volume with the Kmix icon, when you raise the volume lever, as soon as you let go, it goes back down to 0 level. I tried searching, but couldn't find anyone else who complained of the same problem. Using pkilll to kill Kmix didn't help either, it just reloads.

I'm using Debian Jessie (64-bit) with XFCE
Code: Select all$ uname -srvmo
Linux 3.12-1-amd64 #1 SMP Debian 3.12.6-2 (2013-12-29) x86_64 GNU/Linux
And my middle button doesn't work anymore. The problem doesn't seem to be configuration-related as xev, xinput test and cat /dev/input/mice show nothing after clicking the middle button.
Here's the output from xinput:
Code: Select all$ xinput
⎡ Virtual core pointer            id=2  [master pointer (3)]
⎜  ↳ Virtual core XTEST pointer         id=4  [slave pointer (2)]
⎜  ↳ Logitech USB Receiver            id=10  [slave pointer (2)]
⎣ Virtual core keyboard            id=3  [master keyboard (2)]
  ↳ Virtual core XTEST keyboard         id=5  [slave keyboard (3)]
  ↳ Power Button                id=6  [slave keyboard (3)]
[Code] ....
Could it be a kernel issue?

Ctrl-c with middle mouse button (MMB) trigger in running bash script trigger.
The key combination Ctrl-C or "^C" with the keyboard triggered on a running bash script stands for "signal interrupt" (SIGINT) and terminates the process.
For my workflow in the test phase, how I could do that with the MMB-Buffer, followed by the modified script command:
Code: Select allscript runs
script runs
script runs
Signal interrupt and rerun with MMB trigger:
Code: Select all^C; ./script.sh
modified script runs
modified script runs
does not work and 2 hours meta-crawlers

I have Ubuntu Server 10 installed on my Desktop and it seems to shut down every night, requiring me to turn it on each morning. Is there any log/place I can check to figure out what's causing the shutdown?

My server crashed last week and I'm trying to diagnose why. /var/log/messages contains the following error messages, which indicate that the server's memory peaked. I would like to discover what process caused the memory peak. Being that "httpd invoked oom-killer", can I conclude that httpd was the cause of the memory peak?

I am renting a virtual server which is running Linux Debian Etch. I have access through the root account.
I am very new to virtual servers, and also very new to Debian Etch. I am happy I found this forum when trying to research on the Internet.
The things I need to know are:
- Comes Debian Etch with a GUI (graphical user interface) which I can use on the rented virtual server?
- And if not, I would like to ask the community here if there are any GUIs which I could install to that server, and how?
I want to be able to access the server in a much easier way than to have to type each command. I want to use that server to host domains, as soon as I am more self-confident with Debian Etch.

I have a problem with one a server installed with Debian 3.1, that is restarting almost every day at the same hour, 6,25 AM. Here are the messages obtained with #cerberus:/etc# grep -C 5 restart /var/log/messages
.....missing displays....
.....missing displays....
.....missing displays....
As I said, there are days when the system is not restarting, but more often it does. For example, on 6th and 8th October it didn't restart, but on 7th it did, and the messages are the same.

In order to debug a problem, I want to list down as many as possible reasons of a server (SOAP server running on Fedora 10) sneding RST in middle of packet transfer. Please note that in my case, SYN and ACK of initial handshake went through. Server received request from client and started data transfer but then suddenly, server sent RST in between data transfer.

I am not able to SSH into my Debian server from outside. I have four Linux PC's in my home, and the three computers running Arch Linux I can get into just fine, each have their own port forwarded to them via my router. My Debian server, however, I cannot access from the outside. I have the chosen port allowed in sshd_config, and I even tried changing the port to one of the ones that works on my other PC's with Arch Linux. I'm confused why Arch Linux will let me in and Debian won't. I even tried uninstalling iptables completely and that didn't fix it. I can ssh into the Debian server from inside my home, but not from outside. Anyone have any idea what the blocker might be?

I have just installed Ubuntu (/dev/sda7) and Debian (/dev/sda4), but since I have updated all informations on Ubuntu, then Debian did not appear anymore on the grub list. There is an wiki I have found, but I an not really sure about what to do.
Here are the boot informations:
Boot Info Script 0.55 dated February 15th, 2010
Boot Info Summary:
=> Grub 2 is installed in the MBR of /dev/sda and looks at sector 488861020
of the same hard drive for core.img, core.img is at this location on
/dev/sda and looks on partition #3 for (,gpt3)/grub.
[Code]...
ps: on this file, it says that the /boot is installed on the MBR and /dev/sda3. I will remove the boot from MBR as I am now using /dev/sda3 instead. Sorry for my english

I will be relocating to a permanent residence sometime in the next year or two. I've recently begun thinking about the best way to implement a home-based network. It occurred to me that the most elegant solution might be the use of VM technology to eliminate as much hardware and wiring as possible.My thinking is this: Install a multi-core system and configure it to run several VMs, one each for a firewall, a caching proxy server, a mail server, a web server. Additionally, I would like to run 2-4 VMs as remote (RDP)workstations, using diskless workstations to boot the VMs over powerline ethernet.The latest powerline technology (available later this year) will allow multiple devices on a residential circuit operating at near gigabit speed, just like legacy wired networks.
In theory, the above would allow me to consolidate everything but the disklessworkstations on a single server and eliminate all wired (and wireless) connections except the broadband connection to the Internet and the cabling to the nearest power outlets. It appears technically possible, but I'm not sure about the various virtual connections among VMs. In theory, each VM should be able to communicate with the other as if it was on the same network via the server data bus, but what about setting up firewall zones? Any internal I/O bandwidth bottlenecks? Any other potential "gotchas", caveats, issues? (Other than the obvious requirement of having enough CPU and RAM).Any thoughts or observations welcome, especially if they are from real world experience in a VM environment. BTW--in case you're wondering why I'm posting here, it's because I run Debian on all my workstations/servers (running VirtualBox as a VM for Windows XP on one workstation).

I have no idea what is happening but I started getting a problem after some updates and then I decided to upgrade to 11.04 from 10.10 to see if this fixed the problem, then I just did a clean install last night and I'm still having problems. I'm always asleep when it happen or not around so I'm not sure what is happening right before this screen, but I can say I usually will only have VLC open (at this point I'm sure it stopped playing videos) and maybe Transmission in the background, nothing else. The computer won't respond to the Ctr+Alt+B+PrtScn or to the power button, or to Crt+Alt+F2 or the like, seems completely frozen...

I have a script that I'm trying to use to backup my hard drive every night. The full backups are working flawlessly. I haven't figured out the incrementals yet. I thought they were working when I first wrote the script a few weeks ago, but it doesn't seem to be working anymore. I have a long script that I have a whole bunch of statements like this.
[Code]...
To be honest, I'm not a Linux expert and I was really surprised when I started this venture that Linux filing system doesn't have an archive bit like NTFS does and we have to use a file to store the archiving information. But there's the file at /var/log/usr.snar. My theory is I just leave that file for a week so I can create one full and incrementals through the week. Then when I want to create another full backup (when I swap hard drives), I then delete that usr.snar file. I thought that worked a few weeks ago, but it doesn't anymore. When I start my backups, they backup every folder I have listed and not just the files that changed. My full backups are 165 GB, so I'd like to use the incremental feature.

When trying to run MS Communicator 2007 in XP hosted by Ubuntu 9.10 using VirtualBox 3.1.6, the Communicator process inside the virtual image maxes out (90%+) and it becomes unusable (host reports VBox at 50% CPU). If I migrate that image to a Windows host, VBox does not show the same issue (Communicator process ranges from 20-35%). Creating a similar VMware image on the Ubuntu host and running it also does not show the issue (Communicator process ranges from 20-35%). So obviously there is some kind of bottleneck occurring with VBox on Ubuntu. My questions is, how do I figure out what that bottleneck is?

I'm a fairly nocturnal creature by nature, but life requires me to spend more time during the bright hours of day. I also have a visual impairment which makes it that my eyes take a very long time to adjust to darker situations. I need to be able to easily dim my screen so that using my computer doesn't keep me awake as much and doesn't prevent me from doing other stuff.
I will accept both a hotkey based solution "like on most laptop" as a timed one. My main monitor lacks simple brightness/contrast controls. f.lux doesn't suit my needs, since it only changes the screen's color temperature. I'd like the solution to work regardless of the make and model of the video card involved. Wearing sunglasses is impractical, since they make it hard to interact with objects around my computer.

I am running Ubuntu 10.04 and I am thinking of setting up a few X10 lights so that I can turn them on and off at certain times of day/night. I am not to concerned with turning stuff on and off via the web but that might be a nice option. I want to keep it as simple as possible. I have looked over the forums and web but I am not sure about how to start and keep it simple.
