SSH-Test by Tim Chen <[email protected]> Date: Wed May 11 02:39:31 CST 2011
-------------------------------------------------------------------------------
Tools to test for the following the SSH authentications.

public key authentication
host-based authentication
password authentication

-------------------------------------------------------------------------------
usage: ssh-test.py [-h] -a {0,1,2} -u USER -o HOST

SSH authentication test.

optional arguments:
  -h, --help  show this help message and exit
  -a {0,1,2}  the authentication type, 0: public key, 1: password, 2: host-
              based.
  -u USER     the user for public key and password authentication.
  -o HOST     the host to perform the SSH test, for host-based authenticaion,
              the host name must be in FQDN. default: localhost.localdomain
-------------------------------------------------------------------------------
Manual test cases:

public key authentication:
	Run ssh command to do the test
	Require: 
			1)ssh
			2)add user public key to authorized_keys
	Steps to test:
		1) run ssh command: 
			ssh -o StrictHostKeyChecking=no -o PreferredAuthentications=publickey \
			USER@HOST /bin/sh -c exit
		2) check the return code: echo $?
	Expected result:
		Test ok on return code = 0, otherwise test failed.		

host-based authentication:
	Run ssh command to do the test
	Require: 
			1)ssh 
			2)turn on HostbasedAuthentication in server side sshd_config 
			3)add host public key to ssh_known_hosts
	Steps to test:
		1) run ssh command: 
			ssh -o StrictHostKeyChecking=no -o PreferredAuthentications=hostbased \
			HOST /bin/sh -c exit
		2) check the return code: echo $?
	Expected result:
		Test ok on return code = 0, otherwise test failed.

password authentication:
	Use sshpass tool to do the test 
	Require: 
			1)sshpass
			2)ssh
			3)add user password to PASSWORDFILE.
	Steps to test:
		1) run sshpass command: 
			sshpass -f PASSWORDFILE ssh -o StrictHostKeyChecking=no \
			-o PreferredAuthentications=password USER@HOST /bin/sh -c exit
		2) check the return code: echo $?
	Expected result:
		Test ok on return code = 0, otherwise test failed.

Authentication verified on the server side
	Check file /var/log/auth.log
