To all geeks out there, amixer is an alternative sound mixer for your gnu/linux machine. besides alsamixer, amixer doesnt need up down key to control the volume.

example:

amixer set PCM 10%+

or

amixer set Master 10%-

What’s CCL:

CCL (libccls + libcclc) is a library that intends to make the development of internet cafe programs easier, doing some of the work for you. libccls is used to make the server part, and libcclc is used to make the client. It is currently a work in progress, the APIs are subject to changes.

Where you can use it:

It is developed on Linux, but it is supposed to work everywhere SQLite and Glib, and OpenSSL works.

What it does:

This are things it does for you:

• It handles the communication betwen client and server, so you don’t have to care about sockets, and things like that.
• Suport for secure connections using OpenSSL.
• Flexible tarifs system.
• Support for selling products, etc
• Support for members (they can have different tarifs)
• It controls the time of the client sessions, and calculates the price.
• Support for countdown sessions, session pausing, swaping sessions from one workstation to another, etc.
• Logging capabilities, and log searching.

This article will help you how to improve your internet connection speed by tweaking your /etc/sysctl.conf

1. open your /etc/sysctl.conf using your favourite text editor ( gedit, vim, nano, kate, kedit, etc )
2. at the end line of the file, paste this value

# increase TCP max buffer size setable using setsockopt()
net.core.rmem_max = 16777216
net.core.wmem_max = 16777216
# increase Linux autotuning TCP buffer limits
# min, default, and max number of bytes to use
# set max to at least 4MB, or higher if you use very high BDP paths
net.ipv4.tcp_rmem = 4096 87380 16777216
net.ipv4.tcp_wmem = 4096 65536 16777216
# don't cache ssthresh from previous connection
net.ipv4.tcp_no_metrics_save = 1
net.ipv4.tcp_moderate_rcvbuf = 1
# recommended to increase this for 1000 BT or higher
net.core.netdev_max_backlog = 2500
# for 10 GigE, use this, uncomment below
# net.core.netdev_max_backlog = 30000
# Turn off timestamps if you're on a gigabit or very busy network
# Having it off is one less thing the IP stack needs to work on
#net.ipv4.tcp_timestamps = 0
# disable tcp selective acknowledgements.
net.ipv4.tcp_sack = 0
#enable window scaling
net.ipv4.tcp_window_scaling = 1

3. then save

4. after that reload your sysctl using this command “sysctl -p” ( without quotes ) and change your MTU of your eth ( either eth0 or eth1 or wlan0 or something ) using “ifconfig eth0 mtu 1500″.

5. Another thing you can try that may help increase TCP throughput is to increase the size of the interface queue. To do this, do the following “ifconfig eth0 txqueuelen 1000″

6. The other way to tweak your internet connection is using Powertweak. Can be found on debian’s repo or ubuntu’s repo or u can download it at sourceforge

6. test your internet connection, more info you can find at this website and this

tleds and xtleds are Linux programs which blinks keyboard LEDs (Light Emitting Diode) indicating outgoing and incoming network packets on selected network interface.

The Scroll-Lock LED blinks when there was a packet sent and the Num-Lock LED when one was received.

xtleds works both in X-windows and on Virtual Terminal (VT). xtleds needs libX11.so (shared library) to work.

tleds can be run _also_ on systems where there is no X-Windows installed.

Both programs probably work only on x86 and PPC Linuxes or as far as now I haven’t heard anyone using these in sparc/68k/alpha-Linuxes.
Needs read access to /proc/net/dev to work.

TLeds is cool apps to show u incoming and outgoing packet on ur laptops/pcs.

download at tleds-1.04.tgz (26 KB)

To linux’s user, must try this cool stuff!

First of all,

i would like to thank to anybody who helping me buying my new laptop

esspecially to irwan and fenris.

for ur information,

i got so many problem installing operating system into it.

such as no hdd detected, no dvdrom detected and so on.

1st day: ———-> windows xp, ubuntu 7.04 installation failed , no hdd detected

2nd day: ———> got help from irwan, try to install RHEL 5 server & client, SOLARIS 10, and Fedora 7 using network install, then i decided to stay with Fedora

3 or 5 day after that: ————> went to Fenris’s house, and trying to update Fedora 7. While downloading its component, i tried to play DVD using mplayer, guess what ? Fedora 7 said there is no DVDrom!!

next day: went to irwan’s office at excella business park, begging him to help me install other OS that can make me satisfy, i ‘verequest for debian.

summary: i now satisfied with my new debian amd64 (Lenny)

thanks to everybody who gave me strength

credit goes to irwan and mr fenris.
