Debian :: A Bunch Of Random Doubts Interconnected?
Dec 8, 2010
My new laptop has an Intel i7 processor and 6gb DDR3 of ram, I really didn't know which architecture to use and I ended up installing Debian amd64 ( Squeeze because it's the one I used in my older computer ). I decided to add Backtrack 4 R2 repositories to my /etc/apt/sources.list, and after doing:
#aptitude update
I found out that they don't have support for amd64 repos...1st: is it possible to make my aptitude accept the Backtrack's i386 repos? if yes, how? if not, can I switch to i386 and be able my laptop's 6gb ram ? if yes, would that sacrifice a lot of performance?( I did choose amd64 because I thought that I wouldn't be able to use more than 4gb of ram with the i386 build. Is this correct? )
Final note: I want you to know that I already tried to install aircrack from Debian's repos but it's not present, I'm not sure if there's something wrong with my configuration.
*this is what my /etc/apt/sources.list looks like:
#deb cdrom:[Debian GNU/Linux testing _Squeeze_ - Official Snapshot amd64 NETINST Binary-1 20101130-09:05]/ squeeze main
deb http://distro.ibiblio.org/debian/ squeeze main contrib non-free
#deb-src http://distro.ibiblio.org/debian/ squeeze main contrib non-free
i got Debian Lenny 5.0.1 and i'm trying to install the OSCAR cluster.I need to upgrade my OS with the packages in URL...which corresponds to my arch. I'd read while searchin' on web that i need to modify my /etc/sources.list file.
I downloaded the source code of apt using apt-get source apt. The folder I got has the name apt-0.7.6ubuntu13. But the version of apt my system has is 0.7.9ubuntu17.2 (found using dpkg -p apt). Why I dint get the source code of apt currently in my system?

I have been playing with JWM source and found this cool tutorial at Debian Forums about how its easier to generate a .deb vs installing from source in the traditional manner (./configure, make,etc)[URL] My problem is that when doing the command
Code:
dpkg-buildpackage -rfakeroot -us -uc
it starts over, destroys the previous jwm stuff, including my custom files and generates a .deb so, how do I stop it from "cleaning" when i run the above command?
Today I was installing a new system and tried to run an iptables script I have on another machine, in which works flawlessly, and get a bunch of errors:
Looking into /lib there isn't an iptables directory but there's one named xtables. I tried creating a sybolic link:
But, still doesn't work don't know if is a bug or what but have other systems running without problems.
I running this on Lenny 5.0.4 and iptables was installed with apt-get install iptables.
I am trying to get preseed working on a bunch of machines with multiple NICs but it doesn't pick the right interface and/or gets "no link" on all interfaces. My PXE kernel line looks like so (I have auto=true priority=critical and interface=auto)
I'm looking for a script that copies a random .jpg from a random folder in my ~/Pictures folder to my ~/temp folder with a standard filename. This file will then be displayed in Conky. I can fix the last part, but I cannot find a way to do the first part.
System is Wheezy 7.9 with lightdm and MATE desktop.
I have 128GB SSD with various partitions for operating systems and a separate HDD for the /home folders for each OS. Wheezy is my primary system, the others, apart from the original XP are experimental.
/etc/lightdm/lightdm-gtk-greeter.conf is Code: Select all# # background = Background file to use, either an image path or a color (e.g. #772953) # show-language-selector (true or false) # theme-name = GTK+ theme to use
[code]....
The problem is that each time I use the Ubuntu system and I change back to Debian, the greeter background contains snippets of whatever was displayed while I was in Ubuntu. What I don't understand is how this can happen, given that the operating systems are installed in separate partitions with separate /home partitions as well. After I have used Debian and restart, the greeter screen is clear, as it should be.URL....
I try to open an application, and it's painfully slow, and i think "this is weird i've had it open just 10 seconds ago and it should be in the cache". the disk is constantly working, so maybe i ran out of ram and it's swapping, so i check: according to 'free -m', about 200m of 2g ram is used (without buffers/cache), but still also 200m of swap is used, although swappiness is set to 1 (low tendency to swap). so this is not normal.also, kswapd0 is eating pretty much cpu (but not 100%). switching to tty1, logging in, and starting iotop takes about a minute. according to iotop, about 8 random processes (could be a browser, could be some daemon) have 99% IO activity (i'm not sure what that means, how can 8 processes take 99% each?).after the first 3 times, i disabled swap by adding swapoff -a to rc.local, but it's still the same, and kswapd is still among the cpu-eaters.
I have installed Debian Wheezy on my laptop today, which went relativly smoothly. The only problem that is left (for now) is that my wireless LAN disconnects 1-2 times every 30 minutes, just to reconnect a few seconds later. Obviously that is very annoying, especially when watching streams on twitch, videos on youtube and so on.A thread I found on google suggested to use the command dmesg right after my wireless lan connection drops. So I waited for the next disconnect, issued the command and got the following output:
Code: Select allwlan0: deauthenticated from 00:1f:3f:d4:25:6a (Reason: 14) wlan0: deauthenticating from 00:1f:3f:d4:25:6a by local choice (reason=14)
I wondered what that reason code meant and found this website, which states that the code 14 stands for: Message integrity code (MIC) failure
Aprox. 1 time per day / every two days hangs the x-server. It hangs a few secs then is being killed and restarted. A popup window in the task bar tells me the restart of the x-server. After that about 15 sec. I can continue to work but sometimes the gtk2 apps lose their integrity thus I have to restart by logging off and in again.

what does it mean "Remote peer vanished with error" ? Remote access? I am not competent to evaluate that.
Linux version 3.16.0-4-amd64 (debian-kernel@lists.debian.org) (gcc version 4.8.4 (Debian 4.8.4-1) ) #1 SMP Debian 3.16.7-ckt11-1+deb8u5 (2015-10-09)
When I play videos in VLC, the video output seems to randomly freeze while playing the video. This does not effect the audio though. The audio output continues, but with the video frozen on a frame. This is happening in windowed and full-screen mode. I have to use "pkill vlc" each time twice then start VLC again. I have had to resort to mplayer for the time being. I am running squeeze. I was not experiencing this problem before though (started within the past week), so it must be due to some recent upgrade. I have tried "aptitude purge vlc && aptitude install vlc", but I am still experiencing the same problem.
I'm having problems keeping audio working. Using Sparky with 3.16.0-4 kernel on a homebuilt PC. AMD A10-7850K CPU on a Gigabyte F2A88FN-WIFI mobo.
I'm using a set of Logitech Z-5 USB speakers and I repeatedly lose all audio output. To get it back I need to do 1 or all of these steps:
1) Unplug the speakers 2) Kill all processes that may be producing audio (Chrome beta, IceWeasel, Exaile, etc.) 3) Start Alsamixer and select another source in sound card list then reselect USB card #2. 4) The weird one - Remove and then re-add the volume applet that I like to have in the panel. When I lose sound th slider gets "stuck" and will not move. It will not recover.
I may need to repeat this several times but it will come back. Not immediately after any step but after a few attempts it just begins working as long as nothing is trying to produce audio at the moment. Sometimes Alsamixer says that my USB Card has no controls when I reselect it, not every time though.
Most of the time if I have more than 1 source open at any time it is likely to die again, for instance I like to stream Google Play Music. If I pause that but leave it open, then try to watch a Youtube video or other source I will either get no audio from either source, or lose the streaming audio source when I try to restart it. Going through the above routine 1 or more times usually restores it.
I have created asoundrc.conf file to tell system to use USB audio as described here -> [URL] ..... In my case USB is # 3 in the list. So this is my file:
Code: Select allpcm.!default { type hw card 2 } ctl.!default { type hw card 2
I have strange problem with my wireless connection. When I boot my computer, I can connect to my wireless network normally. After a random time between 2 and 20 minutes, I am disconnect and cannot reconnect to any wireless network I have no problems in Windows and Android.
I use the broadcom-sta-dkms driver and the power management is disabled.
Code: Select allrandom: nonblocking pool is initialized and Code: Select allPM: Starting manual resume from disk etc.
When everything is ok boot took around 20seconds. But when this problem occur it can take around 5 minutes. It occure during normal boot, but there are some information about resume from hibernation in log. But I didn't hibernate it. And hibernation doesn't work reliably so I removed uswsusp because I tried to fix hibernation with installing uswsusp first.
My laptop: MSI EX600X-033Sk (C2D T5250, Nvidia 8400g, It has firewire, usb2.0, ...)
I tried to google stuff like "Jessie slow boot", "Stack on random: nonblocking pool is initialized" etc but I didn't found any solution.
Here is few parts of my kern.log:

I'll start at the beginning. The problem i am about to describe occured in ubuntu 9.10 for the first time (https://bugs.launchpad.net/ubuntu/+bug/480850) and is ironically partly responsible for my switching to debian. which i don't regret, but it seems i can't run from the bug any longer because now it's in squeeze, so i want to fix it or make a proper bug report:
Steps to Reproduce: 1: Suspend Laptop to RAM 2: Resume from Suspend 3: Wait and see, preferably monitoring top: At some random time, ranging from immediately (black screen after resume) to several hours later, the system will become unresponsive. Switching to tty1 or Alt+Print+K does not work, Alt+Print+REISUB does work. Each freeze is anticipated by a random process (this time it was mandb, was installing something) hogging 100% of CPU, then the System becomes gradually unresponsive within a minute or so (panel, metacity, finally mouse cursor freezes too). Alternatively, in case of a black screen immediately upon resume, Alt+Print+K works (EDIT: or not), and the system remains usable. Additionally, i don't know if this is related, i noticed one process using 9999% of CPU for a second according to top, just thought i'd mention it. This bug constitutes a regression, suspend does work flawlessly on this Laptop in Lenny.
The above is how it presented itself at the beginning on a fresh squeeze install, however, after two days of trying, i additionally get kerneloops messages i did not get before (again, after at least one suspend to ram) and after that the system becomes generally unstable (random applications won't properly open or terminate, including nautilus, evolution, iceweasel). Can this be due to secondary damage from the freezes and alt+print+reisubbing repeatedly?
The good news is, apart from this probably already damaged squeeze install, i have another one on one of my playground partitons, where i avoided suspend so far, so i can still try things out there. (it's kde, but i don't think it's related to the desktop environment).
I have had a serious problem with my laptop recently. I have been having unexpected reboots and kernel panics and I don't know why. I can't tell if it is hardware or software, and what is causing it.
It has happened on multiple power bricks from different outlets and locations, my slice battery and my main 9-cell battery.
I am running Debian Testing/Stretch with Kernel 4.1 with XFCE4 on a Lenovo T420 with 16 gb of ram, a i5-2540m, USB3 Express Card, OCZ SSD, an intel 7260 ac wifi card and Ericcson F5521GW 3g card. I also have a modded bios for the wireless cards, and I have had that for over half a year without any problems.
I have no clue what the cause is from the logs.
I also booted into Windows for a bit, then it blue screened, but I don't know if it was because of a driver I had tried to put on earlier for the 3g card, because Linux was out of commission and I needed 3g. The driver didn't work, gave a code 10 or something and gave me a blue screen that said something along the lines of device driver attempting to corrupt the system has been caught. Windows also won't boot anymore.
I'm not worried about Windows though, and what I really need is Linux to work, being that this was the first time I booted up into windows in several months.
Memtest runs fine, and passes all tests.
Right when I turned on my computer after one incident, I wrote a script to check the CPU temp and write it to a file every second. Once the computer turned off, I read the file and it said the CPU was at 39 degrees. Not something to turn off over.
I cannot find any indication of a problem in /var/log/kern.log. kern.log was extracted from the computer right after it rebooted randomly. Find it here: [URL] ...
I have been having this problem for about two weeks now where Debian's network and internet connection randomly fails. It works perfectly fine and hosts all the services I need for a while, and then without warning all network connectivity fails. I can't ping any other network device. Regardless of how much I try to fix it, the only thing that works is restarting the computer. First, the server went 7 days without a problem; then 5 days; now it lasted 2 days. Judging from my Teamspeak server logs, it crashed today at 12:31. I grep'd through my log files and found this information:
I have this wired problem with my realtek rtl8101e ethernet. It keeps on disconnecting randomly with my router. My computer is connected to D-link router via LAN cable. This problem does not occur in my windows xp os.
I have to suspend and resume my Debian os (wheezy 7.6 KDE) to get the ethernet connection up everytime it disconnects with my router.
These are my ethernet details

I've just recently upgraded to lenny using aptitude (following the instructions on debian.org. All went smoothly, and almost everything is working fine.I have had my X server crash twice since then, both times when I simply doubleclicked a running application. There is some indication of problems in the Xorg.log file, but it's not helpful to me -- can you help me understand?
Just upgraded to Debian Jessie. I'm having a problem with the desktop and lockscreen that I never had before in Debian 7. Whenever I open the laptop to wake it up, there is very bad discoloration of the background. (screenshot : [URL] ..... )
Hardware is an IBM Lenovo T410 with no customizations. The graphics are factory nvidia. 3D acceleration works flawlessly, and I have no other issues except this background problem.

I've run into something very interesting over the past several months with audio CDs and KDE 4.3.1. Background: I've got two computers running Slackware 13 --stable with Vincent Batts's KDE 4.3.1 packages. One of them is a desktop running Slackware64 and the other is a laptop running 32-bit Slackware. The two computers are running almost the same software too. I like to listen to audio books that I get from the library on my MP3 player. The vast majority of them are CD audio (as opposed to MP3 books), so the disks simply have a whole bunch of .cda tracks on them when I view them in Windows.
HOWEVER, when I view them in Dolphin or Konqueror, I get several folders offering the files in different formats. For instance, there's a folder for the individual tracks as .wav and another for .ogg files. The folder that I really like is one called something like "Full CD," which offers the whole disk in one file in four different formats. That's the one I like. I can get the whole disk in one OGG file so that an entire book is just 12 files on my Sanza. The only thing that seemed strange was that it took for freaking ever to "copy" from the CD to my hard drive.
I think I figure out what's going on! I think that Dolphin is actually calling K3B when I click on the audio CD and when I "copy" from the CD to the hard drive, it is actually encoding the .CDA files. The Problem(s)Until recently, the burn (if that's what it is) was slow on the 64-bit machine, but it worked. However, in the last week or so, it seems that the last few bytes of data to burn are taking forever (like an hour or more) to do so. I hear a strange clicking from my drive, so maybe that's the whole problem. I'm going to get a new drive and see what happens. The burn works well on my 32-bit laptop, but it doesn't recognize audio CDs when I insert them like the 64-bit desktop does. I need to open Dolphin and type 'audiocd:' in the toolbar for it to recognize the disk. Then everything works well. So: Am I understanding what's actually going on with audio CDs? Why does my desktop computer recognize audio CDs when they're inserted, but the laptop doesn't?
Just upgraded to fc12, noticed that there was no menu bar (the one with "file", "edit", etc....) on my users/groups configuration program, but I figured that it was just a change from fc11. But now I'm noticing more stuff that doesn't have one that ought to (gedit, filezilla, and most importantly, nautilus).On the other hand, firefox does have the menu bar, so it's not a global issue. I have compiz-fusion/emerald, although I'm not sure that would make a difference. I've tried a few different themes thinking it might be the theme I'm using, but no dice.
I have contacted Novell by telephone and they can' support the OpenSUSE OS.I'm downloading via a library (window's XP) computer and it does not download every thing I tell it to; so I have to often go back and some times I am sure I don't go back because I don't notice or can't figure out that I'm missing something. Also when I try to download any part of the repositories I have to (to bring it home and install it on my computer openSUSE 11.4 KDE,) sit there and click right, click open in new tab, go to the next one repeat.... and then once you reach the bottom of the screen you minimize the web page, and then click save, then tell it where to save, then go to the next one.......
1: put each and every repositories into a bunch of .tarbz2 (or any other achiving method,) files (700 MB would be greate,) so I can bring them home easier; reassembling the achives is mutch easier ten not downloading what I need and it takes mutch less time.
2: send me an E-mail doark@mail.com detailing how to tell your machine: 2A: it's a sever 2b: it's serving X and X infomation 2c: when someone types in lets say "free software" my website is in the choises (in other word advertizing,) and 2d: where to send the money it gets from someone logging on to my web page.
