I have completed first project
For Broadcom BCM4301 BCM4303 BCM4306 BCM4309
BCM4311 BCM4312 BCM4318
Install b43-fwcutter. This is the software package that does the extraction of the firmware from the proprietary driver.
Code:
[root]#su -
[root]yum install b43-fwcutter
Determine which native driver is being used by the wireless card (b43 or b43legacy). The kernel is generally good about detecting a Broadcom wireless card and loading the correct driver module for it. The following terminal command will list the loaded kernel modules in alphabetical order. Look for b43 or b43legacy.
Code:
[root]#lsmod | sort
Do this step only if you need to install version 4 firmware for the b43 driver module. Copy and execute the following command lines one after the other in a Fedora terminal.
Code:
[root]#wget http://downloads.openwrt.org/sources/broadcom-wl-4.150.10.5.tar.bz2
[root]#tar xjf broadcom-wl-4.150.10.5.tar.bz2
[root]#cd broadcom-wl-4.150.10.5/driver
[root]su
[root]b43-fwcutter -w /lib/firmware wl_apsta_mimo.o
For Broadcom BCM4311 BCM4312 BCM4313 BCM4321
BCM4322 BCM43224 BCM43225 BCM43227 BCM43228
BCM4328 BCM43XG
1) Install the RPM Fusion repositories.
To enable access to both the free and the nonfree repository use the following command:
For Fedora 15, 16 and 17:
[root]#su -c ‘yum localinstall _nogpgcheck http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-stable.noarch.rpm‘
2)Do this step only if you need to install the kmod version of the driver for the i686 or x86_64 kernels.
[root]#yum install kmod-wl
sir,
i am trying to install wifi driver in fedora
but after following commands some error is occuring
su -c ‘rpm -Uvh http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm’
su -c ‘rpm -Uvh http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-stable.noarch.rpm’
error is

sir please start a thread for project 11 .apart from it sir there are no documents after vectored read and write in our account ….
completed installation of fedora, configured remote logic services(TELNET and SSH), ftp, tftp servers
Completed installation of fedora, configured TELNET, SSH, FTP, TFTP servers till 3rd October.
sir i have implemented the ipc mechanism using fifo ,message queues and semaphores..
havent notices any need for shared memory..
all the clients are getting the right data they are requesting for..
The purpose of this discussion is to get the participants familiar with the 
different mechanisms that are available for communicating between two or more processes. Inter-Process Communication, which in short is known as IPC, deals mainly with the techniques and mechanisms that facilitate communication between processes. Now, why do we need special separate mechanisms or techniques for communicating between processes? Why isn’t it possible to have information shared between two processes without using such special mechanisms?
In computer science and information theory, data compression, source coding,[1] or bit-rate reduction involves encoding information using fewer bits than the original representation. Compression can be either be lossy or lossless. Lossless compression reduces bits by identifying and eliminating statistical redundancy. No information is lost in lossless compression. Lossy compression reduces bits by identifying marginally important information and removing it. The process of reducing the size of a data file is popularly referred to as data compression, although its formal name is source coding (coding done at the source of the data, before it is stored or transmitted).
when i am installing xineted.
i got following error message.
Insufficient server config – no servers found. Aborting.

this error is occuring .
the document of linux part 1,2,3,4 are not open please open it

i got this error :

[Errno 4] IOError:
how to solve this??
In message queue if i use pointer for sending payload instead of character array then unpredictable output occurs . Sometimes segmentation fault or sometimes unwanted output occurs at the receiver side . When i use character array instead of pointer all works well .
Why is this happening????
