lsofThe author of the article below says he uses lsof most for getting network connection related information from a system, but netstat is just as useful and made specifically for this particular purpose. lsof will do more than network connections, though. It will also tell you what files the program has open in addition to unix sockets and libraries. Of course you could also get all this from /proc but lsof makes it nice and easy. 'of' is actually for 'open files'. http://dmiessler.com/study/nix/commands/lsof/or http://img231.imageshack.us/img231/5250/lsofhh8.pngYou can use lsof to find out what is using your sound card (if it's FireFox, it's probably some YouTube video or some such multimedia piece of embedded Flash): CODE lsof /dev/snd Other great commands you'll love: 'watch', 'strace', 'ltrace', 'iostat', 'vmstat', 'tcpdump', 'truss', 'netcat' (nc), 'wget'. http://en.wikipedia.org/wiki/Watch_(Unix)http://en.wikipedia.org/wiki/Stracehttp://en.wikipedia.org/wiki/Iostathttp://en.wikipedia.org/wiki/NetstatJust as useful or better network monitoring tools / options: iptraf: http://www.linuxhaxor.net/2007/08/27/iptra...ed-lan-monitor/itrace: http://www.linuxhaxor.net/2007/07/17/backt...ing-all-itrace/intrace: http://www.linuxhaxor.net/2007/07/16/backt...ng-all-intrace/tcptrack: http://www.linuxhaxor.net/2007/09/04/sniff...-with-tcptrack/_________________________________ http://dserban01.googlepages.com/linkedin....abap.basis.html

[c/c++][linux] Linking With A -l Is Static Or Dynamic?
How will it effect distribution and portability? (0) It has been a long time since I coded in C/C++ and I can't seem to remember the exact mechanism
of linking. Say, I compiled and linked the source code given at SQLite quickstart guide (C
example in Write Programs That Use SQLite ) in Linux(Ubuntu) environment: g++ -o"SQLiteTest"
./sqlitetest.o -lsqlite3 It gives me a nice executable SQLiteTest and I can use it on my
system. But how would it fare when I distribute that code to someone else? Is the libsqlite3.*
statically packaged into SQLiteTest? or is it dynamically linked and the recipient of the prog....
Which Linux Version For Newbies?
Give your opinion (14) Hi, well i have been a windows user all my life, and I'm really satisfied with it. But from a

Playing Two Wav Files Simultaneously In C#
(4) I have reached a dead-end, in trying to code the Audio Engine for the game - Bomber Man . The
current engine uses the native functions(waveOutOpen, waveOutWrite, etc) declared in Winmm.dll file.
While this allows me to play two sounds together (the Background music and the sound effects), it
causes frequent memory corruptions. For instance, it changes the value of an integer variable
located in a different and unrelated class. I spent hours trying to find out why the value was
constantly changing. When I disabled all the sounds, the problem didn't occur. I used a mo....

My Review And Experiance Of Ubuntu Linux
(4) I have been using Ubuntu 7.10 for about a month now. My experiance began when I sent a request for a
free CD to be mailed to me. Several weeks later, it arrived, however I was reluctant at first to
install it, as there was much hassle when I attempted to install my BCM43xx wireless network drivers
for another distro, Suse. Although I had ran a server on Linux for a while previously, it was easy
to do as Linux automatically detected the wireless network card I was using. This was on an older
computer that I ran the server. On my current pc, a Dell Inspiron 1300 Laptop, a ....

interesting facts about the devious ways in which Microsoft is trying to derail Linux, most recently
through vague legal threats to enforce patents against Linux distributors that it does not partner

What Made You Switch To Linux?
(60) I first tried Linux a few years ago, not because I was completely against Windows or anything like
that, but just because I had some free time on my hands. I started off with Mandrake 9.0 which was
very user friendly and Windows-like. After reading through a bunch of message boards and learning
which distros are good for what, I soon realized my current distro was great for Linux noobs. So
then I decided to try something a little more advanced like Slackware which I knew had a steep
learning curve. Since then I've been using Slackware as my main OS and couldn'....
