When you download linux drivers for devices such as wireless dongles, you'll get a folder full of random files that I'm assuming oyu need to compile? How do you install a wireless driver in linux?
I'm about to hold a course for learning Linux. I'd like the participants to see what keys and key combinations I press. Is there anything like Mouseposé for Linux?
I'm managing Linux servers for my team. For each new instance, I install the following softwares:
etckeeper which keeps tracks of every changes in /etc
shorewall to have a simple setup for firewall
rsnapshot which keep incremental backup of important directories
cron-apt takes charge of update of the system (or, in my case, send me an email to warn me about new updates)
But I was wondering if you administrators have any other wonderful tools for daily management. I'm not talking about remote management (like cfengine) but little tools which help to manage a small number of Linux servers.
I added Linux boxes to /etc/hosts.equiv and .rhosts file for rsh connectivity to HP box.
I am able to do rsh as root from Linux to HP. But if I run in a root shell as different user connection times out. Any reason?
I have a dual boot system that works great. I have Ubuntu and XP 64 on one disk and XP on another disk. The Linux boot loader asks me which system to boot, but if I reboot and forget to hit a button, it goes to Linux by default. I would like to boot to XP by default, but somehow retain the option of choosing.
Does any know if there is a way to enable TRIM support on Linux for SSDs? This is included with Windows 7, and I was surprised that I couldn't find much information about it under Linux.
Info on SSD and TRIM can be found here - http://www.anandtech.com/storage/showdoc.aspx?i=3531&p=10
On a Ubuntu 9.10 system:
$ uname -a
Linux ionut-laptop 2.6.31-14-generic #48-Ubuntu SMP Fri Oct 16 14:04:26 UTC 2009 i686 GNU/Linux
the files /var/log/wtmp and /var/log/btmp are empty:
$ ls -la /var/log/?tmp
-rw-rw---- 1 root utmp 0 2010-04-10 16:54 /var/log/btmp
-rw-rw-r-- 1 root utmp 0 2010-04-10 16:54 /var/log/wtmp
Because of this, the last(1) command is not working.
What to do?

What would be a good setting to free memory on linux? I have 8GB but gets used up so fast.
current settings:
kernel.sched_min_granularity_ns = 10000000
kernel.sched_wakeup_granularity_ns = 15000000
vm.dirty_ratio = 40
kernel.pid_max = 4096
vm.bdflush = 100 1200 128 512 15 5000 500 1884 2
What settings would I need so linux frees old ram faster?

Hi,
I have a simple home network with Windows 7 machines and Linux machines (Fedora 12 and 13). I'd like to be able to resolve the Linux machine names from the windows machine. For example:
-- Windows 7
ping mylinuxmachine
Currently this does not resolve. Any ideas?
Thank you,
Martin
Hi,
I'm planning to test my Linux box and I want to start in memory testing. But my problem is what should I need to test the memory in my linux box? Should I need a tool? Or there are some APIs to use to build some scripts?
Thanks
I'm running VirtualBox in Windows. I have Linux 10.04 installed as a VM.
Whenever I log in I have to run to following command to mount my shared Windows web dev folder:
sudo mount.vboxsf web_apps /mnt/web_apps
Where can I put this line (minus the sudo) so that it will run once when Linux boots up? I'm guessing there must be a root .profile or .login script that runs at some point?
I am going to be administering a small network of linux based workstations for a charity institution (not all have the same distro- some are ubuntu and some are fedora). Is there something in Linux that is similar to group policy in windows?. For example I would like to standardize the wallpapers - have only firefox as a browser - default VLC as the media player etc etc.
Thank you, any suggestions are very appreciated.
Im looking for the most compact, best performing & easiest flavor of Linux in which INFORMIX-SQL 7.3 is supported. I have looked at PCLinux. The ISQL app is single-user and the end-user is very familiar with DOS, but frightened by Linux.
Hello! I am constructing a small robot based on an embedded board running linux. I am looking for a USB thermometer device, which will work with 2.6 kernel. So far I found a bunch of devices, but it's not clear whether they have linux drivers or not (no description).
Thanks in advance.
I was thinking of setting up a partition on my Vista comp and installing Linux on that partition. I was gonna install Ubuntu on this partition. I was wondering if the equipment I have (i.e. video card, mouse, keyboard, network card) would be potentially unable to work on a linux platform? Any advice on doing this? I havent started yet, just doing my homework.
Thanks alot, any answer is always appreciated
hello, can somebody recommend me good Linux text editor for Windows (if it exists), I wrote scripts for C-Shell using txt editor of windows but I have problem, it doesn't run cause windows is not UNIX, what can I do? I don't want to install linux for a few scripts, I do testing of my scripts via unix server (this server is not mine), thanks in advance
There are some programs which can display used disk space using a treemap, such as WinDirStat for Windows and KDirStat for KDE/Linux:
I'm looking for something similar, but for a headless Linux box. (E.g. run console data collection program on the server, then load the file in a graphical program in a GUI environment.)
Alternatively, what are other good ways to get a structured used disk space representation, with just SSH access?
After updating to the latest version of Chrome (33) on my Gentoo Linux box, certain sites such as GitHub have started rendering with ugly, pixelated, non-antialiased fonts. Small text is now basically impossible to read.
Before this, GitHub had looked the same to me on Windows, Linux, and Mac computers. So what has happened here and how can it be fixed?
EDIT: Appears to be fixed on the stable release of Chrome 34.
Just to note I am not having a problem at the moment, but have had previously so it sparked my curiosity...
When a computer locks up suddenly to so caps lock flashes incessantly and the only possibility to restart....how do you troubleshoot what is causing it? On Windows there would be some errors in the event log...on Linux it seems there is no opportunity for anything to be written to the log, making it hard to troubleshoot...
In this case, how would you troubleshoot the problem through linux?
I owned a linux server. Now there are several users want to build web services on it, but they require different enviroments. For convenience I give a KVM virtual machine root permission to each user.
But obviously the linux server has only one IP. How can I deliver the external requests to corresponding virtual machine?
(I expect it's somewhat complicated. If so I want at least some docs/websites I can start reading.)
Hi,
I have installed "Damn Small Linux" on my home computer for doing C development in unix. But the distribution doesn't by default come with the C development environment and I am facing some issues when trying to install the gcc.
Is there any other small Linux distribution which by default has the required packages for the C development. And also I don't want additional software which takes up lot of space but still would like to have the graphical environment.
Thanks
Is there a way to use rdesktop or another Linux client to connect to a server that requires Network Level Authentication?
From Windows Server 2008 R2 -- Control Panel -- System And Security -- System -- Allow Remote Access there is an option that says "Allow connections only from computers running Remote Desktop with Network Level Authentication". So with this enabled I can con not connect from Linux. I can connect from XP but you need SP3 and I had to edit a couple of things in the registry for it to work.
Is there a way to watch Linux boot as though it was a program compiled with GCC on a Linux environment using the -g switch so, say, I can step through the entire boot sequence from GRUB onwards, choosing to step through at C source level or assembly when necessary/desirable, by using GDB or a GDB-like tool?
I suspect it would require a virtual machine at least, to watch the boot on a host environment. Any elaboration on this topic of observing a boot would be appreciated!
