ssh - ignore case sensitive to hostname via connection

 How to set icase sensitive to hostname via ssh connection?

You know this....."Please check connection of 3000 servers..." and output is excel when hostname are upper case lower case ....

Why people using excel? For torturing linux administrators!

solution: 

1) create in your home directory file .ssh/config

vi .ssh/config

2) StrictHostKeyChecking=no

martin@princ_bajaja:~$ cat .ssh/config

StrictHostKeyChecking=no

Our outputs: 

 ssh root@fire-lsns

root@fire-lsns:~# 

 ssh root@FIRE-LSNS

root@fire-lsns:~#

now it is time for the life saving of Slovakia : 

root@fire-lsns:~# echo "oh shit, I am stupid idiot" > /boot/grub2/grub.cfg ; reboot
