How do I accurately observe and measure the amount of virtual memory utilization and activity on Linux? I know there is vmstat, but how do I interpret the results? Or, what is better?
I'm looking to install a Linux distro on my Windows 7 machine. Could anyone suggest any tools to handle the multiboot? (I may install 2-3 distros to try out)
This is the standard question, "How do I set a process limit for a user account in Linux to prevent fork-bombing," with an additional twist. The running program originates as a root-owned Python process, which then setuids/setgids itself as a regular user. As far as I know, at this point, any limits set in /etc/security/limits.conf do not apply; the setuid-ed process may now fork bomb. Any ideas how to prevent this?

If a Red Hat or other Linux host has a conflict with an IP address, is there a way to have it display a warning message on the console or in a log, like Windows and MacOS do?
i.e. my computer has an IP address configured (or received from a DHCP server) but finds another device on the network using the assigned address. Will it log the conflict?
hello
i compile & run a C program in linux terminal (using gcc). the program recieves as an argument a text file, parses it and outputs to screen and/or another text file.

thanks
Hi!
Is there a possibility to use a flash drive as a speed up for conventional hard disks? I got the idea to redirect all read ops to the flash drive if the data is already stored there, and to read from the conventional disks if the data is not found there (and during idle time the freshly accessed data from the conventional disk is stored on the flash disk).
Is this already possible with linux standard tools?
I'm going to be building a fancy new desktop soon, and I want to experiment with file systems. I know that ext3 is the most common for linux, but what about ext4, or zfs? Are their any pros or cons to certain ones?
I won't be doing anything spectacularly off the wall, just using it as my main box. It is a good possibility that it will double as my web server, though.
There are a few choices of music managers for linux. I am trying to decide on one also suports mp3player sync.
Can you tell me what app are you using and what cons and pros did you find for that app.
Thanks
Brand new to Linux. I need to turn my box off and put it in my server room. The help here and everywhere seems not to work for me:
http://debianhelp.co.uk/shutdown.htm
I get:
lukepuplett@uktnlx01:~$ poweroff
-bash: poweroff: command not found
lukepuplett@uktnlx01:~$ shutdown
-bash: shutdown: command not found
lukepuplett@uktnlx01:~$ modprobe apm
-bash: modprobe: command not found
lukepuplett@uktnlx01:~$
I also tried halt, reboot, goaway, and pleasejustwork.
What would the best Linux operating system for hosting a Web/SVN/etc. server? One thing that it needs to have is no windowing system installed by default.
Thanks in advance!
This is probably trivial, but I'm quite new to Linux and I was unable to find any info online.
In a folder, I can execute the command find . -regex '.*py' and get the following result:
./.#netMHC3.2.py
Is this a file in the current directory? What can I do to display its contents?
Thank you
I want to embed my network connectivity application into a linux installed rack-mount server and sell it bundled. I googled some but couldn't figured out which it would be?
Do you have any experiences with these types of hardware and recommend some?
on windows there are several key maps applications that replaces Caps lock with ESC on a single 'press and relase' and with a Control signal if hold and another key is pressed.
Is there any way to do something similar on linux? Ideally on the whole system, but if it is only for X window it is fine too.
i'm currently writting scripts with the xautomation package tools. but i guess there is already a better way to do that via configurations.
Is there any Linux command which remembers directories I changed, and shows its stack with interacting operation to choose a directory such as pushing an arrow key on keyboard? This must be different from the way pushd/popd/dirs do.
Don't ask why, but I would like to know a linux command, besides "la -laR", since that could not take that long according to where you are in the folder structure, that takes much time to complete.
Thanks for your help.
What are the advantages / disadvantages of using cooperative linux like portable ubuntu for example compared to a qemu or any other virtual machine installation. Is one option notably faster than the other plus and other things that should be taken into consideration.
I have a linux (CentOS 5.2) server with the name myserver.mycompnay.com, which is correctly returned when I run 'hostname'. When I run 'hostname -s' however it returns "localhost" which is causing some backup scripts to put stuff in a "localhost" directory instead of a "myserver" directory.
All of our other CentOS boxes correctly return the first part of their hostname when 'hostname -s', where do I go on this server to make it behave the same? Other than having "HOSTNAME=myserver.mycompnay.com" in /etc/sysconfig/network what should I be looking at?
If so which version please?

Does anyone know of a program/script that runs on Linux that can give us a nice GUI for browsing and managing shared system folders similar in the way that windows explorer would work?
So would allow, upload, download, file modification etc. It's a way to still have access to all our files stored on the system from any location with internet access.
Thanks in advance
Hi,
is there a way to provide post-mount and pre-umount scripts in Linux ?
I am trying to do some scripts on storage media when mounted and before umounting (for synching).
Any help appreciated.
Every time my computer (Gentoo linux) reboots the clock is several hours off:
/etc/localtime is set for the correct timezone
/etc/conf.d/clock lists the correct timezone
running sntp -r 0.gentoo.pool.ntp.org fixes the problem... until reboot
setting the time manually using date also fixes the problem... until reboot
The System clock is set to UTC
This is starting to drive me nuts :(
I am interested in a utility or process for monitoring disk IO per file on CentOS.
On Win2008, the resmon utility allows this type of drilldown, but none of the Linux utilities I have found do this (iostat, iotop, dstat, nmon).
My interest in monitoring IO bottlenecks on database servers. With MSSQL, I have found it an informative diagnostic to know which files / filespaces are getting hit the hardest.
