Git Submodules basic explanation

Why submodules?

In Git you can add a submodule to a repository. This is basically a repository embedded in your main repository. This can be very useful. A couple of usecases of submodules:

Separate big codebases into multiple repositories.

Installing Kerberos on Redhat 7

This installation is going to require 2 servers one acts as kerberos KDC server and the other machine is going to be client. Lets assume the FQDN's are (here cw.com is the domain name, make a note of the domain name here):

Kerberos KDC Server: kdc.cw.com
Kerberos Client: kclient.cw.com

Important: Make sure that both systems have their hostnames properly set and both systems have the hostnames and IP addresses of both systems in

	DateTime.ToString() Patterns

	All the patterns:

	0 MM/dd/yyyy 08/22/2006
	1 dddd, dd MMMM yyyy Tuesday, 22 August 2006
	2 dddd, dd MMMM yyyy HH:mm Tuesday, 22 August 2006 06:30
	3 dddd, dd MMMM yyyy hh:mm tt Tuesday, 22 August 2006 06:30 AM
	4 dddd, dd MMMM yyyy H:mm Tuesday, 22 August 2006 6:30
	5 dddd, dd MMMM yyyy h:mm tt Tuesday, 22 August 2006 6:30 AM

	This demonstrates how to make client side certificates with go

	First generate the certificates with

	./makecert.sh [email protected]

	Run the server in one terminal

	go run server.go

	USER_NAME=marcy

	sed -i "s/.RSAAuthentication./RSAAuthentication yes/g" /etc/ssh/sshd_config
	sed -i "s/.PubkeyAuthentication./PubkeyAuthentication yes/g" /etc/ssh/sshd_config
	sed -i "s/.PasswordAuthentication./PasswordAuthentication no/g" /etc/ssh/sshd_config
	sed -i "s/.AuthorizedKeysFile./AuthorizedKeysFile\t\.ssh\/authorized_keys/g" /etc/ssh/sshd_config
	sed -i "s/.PermitRootLogin./PermitRootLogin no/g" /etc/ssh/sshd_config
	echo "${USER_NAME} ALL=(ALL) NOPASSWD: ALL" >> /etc/sudoers
	service sshd restart
