Prequisites :

1)know how to edit files
2)Root Permission

First logged in with root account [ either via console or via graphics ]
NOTE : USER CAN USE SUDO COMMAND ALSO

Then edit the /etc/fstab file
edit the following in the file
/dev/disk/by-id/scsi-URDEVICE_ID /windows/C ntfs-3g users,gid=users,fmask=133,dmask=022,locale=en_US.UTF-8 0 0

to following fmask and dmask
fmask=000,dmask=000

so that it should look like this
/dev/disk/by-id/scsi-URDEVICE_ID /windows/C ntfs-3g users,gid=users,fmask=000,dmask=000,locale=en_US.UTF-8 0 0

now unmount the volume and mount it again
#umount /windows/C/
and remount by
#mount -a

and the drive will be mounted with full access

If you have any problem please you are free to contact me [ comment here for it ]

Note:- I shud not be held responsible if you cause any data loss [ though nothing happen with me still its nice to write warning ]

#!/bin/bash curl -u username:password -d status=”$*” http://twitter.com/statuses/update.xml

Replace the above user name and password with your own credential Step Three Set a cron job [ cron job will run your script after every specific time ] to set cron job just log into superuser mode and pass following command [ this command checked on Redhat,Fedora Core and Suse]

#crontab -eu root

and after that command add the following lines into your cron job

*/10 * * * * /bin/sh /path/to/your/twitter/script.sh My PC uptime is $(uptime)

If you need any sort of help or to get a customized output please feel free to leave comment and save the cron job and restart the cron job To restart cron job in REDHAT and FEDORA CORE

# service crond restart

For Suse [ I've tested this on suse 11 ]

# service cron restart

So now Your PC will update its status over twitter every 10 mins to change. If your want your PC to send his update every one hour use following

* */1 * * * /bin/sh /path/to/your/twitter/script.sh My PC uptime is $(uptime)

The Following Expectation have been taken from the author to the reader !!!

1)You might be running Fedora , Redhat or Suse [ altough I've not tested on ubuntu / debian the process may be same ]

2)You know basic vi / vim operation !! you need this knowledge to know how to save a file !!

3)you know basic of crontab . BTW if you dont know I will explain it just leave your comments

4)User should not abuse the service of twitter for this !!

5)User Will add a cron job for deleting root mails too or have any other solutions [ you will get a mail in inbox everytime when a cronjob is executed ]

Special Thanks to Anoj Ramaswamy Sundar for http://anojrs.blogspot.com/2008/03/twittering-from-command-line.html This is base of the whole article without which it was not possible to write this article apart from getting only uptime you can even know your server status

*/10 * * * * /bin/sh /path/to/your/twitter/script.sh $(service mysql status)

above will publish mysql status [ replace mysql with mysqld in fedora and redhat ]

The following packages are needed for compiling kernel

glibc-headers

glibc-devel

cpp-*

binutils-*

gcc-*

Optional Packages [ require on method of Compilation ]

if using xconfig method

tcl-*

tk-*

or qt3*

if using menuconfig

ncurses*

ncurses-devel*

Please note * means version and machine architecture

Download the kernel versions from kernel.org site and extract it
now following commands are to be fired [ as this is short note no details about command are given ask question by commenting ]

#make mrproper

#make xconfig  –> Graphical and best way

#make menuconfig
The above two option are for customizing kernel accordingly to requirements

#make dep

#make clean

#make bzImage

#make modules

#make modules_install

#make install

and yes it is installed

NOTE:- EXECUTING SOME COMMAND MAY TAKE SOME TIME AND SYSTEM RESOURCES

Why to use Yum if I can install RPM using rpm command?
Well if you want to install RPM you have to make sure that its dependencies are also installed . But this is not in the case of YUM you can simply install package with its dependencies. YUM take care of your all install things . Also update feature is not available in the rpm installation method but it is available in yum.

Here are some key features of “Yum”:
• Multiple Repositories
• Simple config file
• Correct dependency calculation
• Fast operation
• rpm-consistent behavior
• comps.xml group support, including multiple repository groups
• Simple interface

Starting With Creating Your Own Repository [Server Side Configuration]

Step First : Check Prequisites
-Have Your Distro CD/DVD

-Check if you have free space on your Hard Disk or not [Total space required vary from Distro to Distro]

Step Two : Copy Disc to Hard Disk
First mount your CD/DVD and copy it to hard disk
cp -avr /cd/dvd/mount/point/ /destination/directory/

Step Three : Intalling CreateRepo Package
Now go to your directory where you copied the files and search for createrepo-*.rpm file * may be different from version to version and system architecture
Install that rpm using rpm command
install using following command
rpm -ivh –aid createrepo-*.rpm

Repeat this step with your all you cd .
Note:- If you want install Repository on your network thrugh ftp or http upload in their respective default directories i.e /var/ftp/pub for ftp server and /var/www/html for http server.

Step four: Run createrepo
Go to the directory where you copied the file and run the createrepo command
createrepo -v .
[please note that “.” {dot} after that command as we are in present directory ]

Now you have done all thing.
Now we will see Client side setting

Client Side Setting For YUM

Create a repo file in /etc/yum.repos.d/ directory [ you can name anything to ur file make sure a .repo extension is added later on]
vim /etc/yum.repos.d/my.repo

add following date in that file

[Myrepo]
name=Any name you want to put
baseurl=file:///destination/directory/
enabled=1
gpgcheck=0

The first line is alias given for your repository . This help to indicate/find that from which repository the package is available.
Second line is name which you can put any thing
Next comes baseurl
base url supports different protocols like file:// ftp:// httpd:// etc. if you are running repository from local pc then give absolute path after file:// . for ftp give ftp://server_ip_or_domain/pub_dir_or_accessable_dir or http://server_ip_or_domain/dir
next line is enabled this specify if yum should enable that repo server for installtion or not 1 is for enable and 0 is for disable
gpgcheck is for checking gpg key. as I don’t required it so I disabled it if you enabled it then you hav to add one more line after that
gpgkey=/your/path/to/key

after this save that repo file and run following command
yum clean all [ will clean yum database ]
yum list [will list the files / packages available on that directory ]

If you find some difficulty in using it please feel free to contact us

Note:- SElinux or Firewall may conflict sometimes [ for ftp and http service ]
Note:- I used RHEL server 5 edition . This process is same for RHEL 4,5 FC [versions I don’t know]

eg.
cd /boot

man command [ replace command with your command press enter ]
eg.
man history

info :- same as man
info command [ replace command with your command press enter ]
