Split large file into smaller files – Linux April 10, 2010

Here is a small trick to split a big iso file (or any other big file) into smaller files of your desired size.
Use the SPLIT tool that comes with your OS.
Suppose I have a big iso file name “bigfile.iso” of size more than 3 GB and I want to split in into smaller iso files of size 1GB.
Here is how to do it:
split --byte=1024m bigfile.iso smallfile_
what this command will do?
It will actually split the bigfile.iso file into smaller files of size 1GB having names – smallfile_aa, smallfile_ab and so on…
So just enjoy the split, now.
And remember you can always use the CAT command to join them again:
cat smallfile_a* > newbigfile.iso

We all know that TELNET because of its weak authentication doesn’t allow “root” user to login.
But there is a TWEAK that will allow TELNET as ROOT.
STEP #1 – Install TELNET
yum install telnet-server
STEP #2 – Make TELNET active. Edit “/etc/xinetd.d/telnet” file and make
disable = no
STEP #3 – Configure PAM to allow TELNET as ROOT. Edit “/etc/pam.d/remote” file and find and comment this line
auth required pam_securetty.so
#auth required pam_securetty.so
STEP #4 – Restart the TELNET service
/etc/init.d/xinetd restart; chkconfig xinetd on
ENJOY the TELNET with ROOT credentials (at your own risk please)
God Bless.

Configuring YUM server for automatic notification to clients March 31, 2010

We have a situation. We have 100+ client machines in our network and whenever some new package is available on YUM, I want all the clients to get updated for the new package via email so that they can use the package, if they need.
How to configure YUM to send email for updates available on server.
STEP #1 – Edit /etc/yum/yum-updatesd.conf
STEP #2 – Edit / Add these lines:
emit_via = email
email_to = staff@yourdomain.com
email_from = yumserveradmin@yumserver.example.com
STEP #3 - Save and Restart the service.
service yum-updatesd restart
chkconfig yum-updatesd on
So now your YUM server will be sending a email to staff user (it can be aliased in your MTA configuration) whenever a new package is available.

Making Directory Listing – Make Sense !! March 28, 2010

Normally when we give “ls -l” command or “ll” command it shows us all the files and directories in alphabetic order.
Sometimes it will be pain in the neck, if you are looking for a directory or looking for file. (as it will show you both)
There is as such no command available (to my knowledge) which will show you directories only and files only, as per your specification.
But we can do a SMALL tweak, to make our job easier.
Here is the command to view directories only :
ls -l | egrep '^d'
And, here is the command to view files only :
ls -l | egrep -v '^d'
You can also create some alias for these big command, as it is not practically good to write the same code again and again
alias llf="ls -l | egrep -v '^d'"
alias lld=ls -l | egrep '^d'"
You can always use “.bash_profile” file to make these aliases permanent.
