What I learned Today " Password less login for your servers "

Hi all ,

Even though some of the servers are  compromised using passwords , So to avoid those kind of issues we have to setup Password less login to ensure high safety and security to our servers.

Steps : Create SSH keys to your user id in your server , use bellow commands to create SSH keys ,

cd ~/.ssh
ssh-keygen -t dsa -b 1024

Create an PEM key from an gerenated PRIVATEKEY

openssl dsa -in id_dsa -outform pem > test.pem 

Copy generated Public key to Authorized_keys file,

cat id_dsa.pub >> authorized_keys

That's it we are done with the key generation. We have to do is to copy that pem key to 

local machine and log in to  that server with this pem key.

ssh -i "test.pem" username@servername 

That's it we are good to gooooo.....!!!!!

Completed first python script on Excel automation

I am happy to share that I finished excel  automation for my official work.I actually used openpyxl for my xlsx automation. I feel great when I done it. Before that I thought automating an excellent work is bit difficult but  once you learn to do, it's mind blowing.

I'm trying to automate xlsx works for an little bit of an time. But due to some backlogs I didn't finish it on the expected time period.

What I learned today sep 30th 2015

I find out that search and replace for an file using SED editor

sed -i 's#055#007#' /etc/login.defs ; grep UMASK /etc/login.defs

above command replaces 055 value in login.defs to 007,
this may looks like simple, but it is more powerfull stuff
