I have always asked this question to my colleagues as to "How do i restrict Multiple Logins in an Active Directory Setup"
So here is the answer
Create a file when a user login and check for such file each time the login request is received if file exists logoff, if file is not present Login and create the file. Its that simple

Using remote shells is all time favourite but remembering those many passwords is a pain so here are the steps to login using SSH without putting a password :)
1. Create a public ssh key, if you haven’t one already. Look at ~/.ssh. If you see a file named id_dsa.pub then you obviously already have a public key. If not, simply create one.
ssh-keygen -t dsa should do the trick. Please note that there are other types of keys, e.g. RSA instead of DSA.
2. Make sure your .ssh dir is not publically writable
# chmod 700 ~/.ssh
Apache is the most common web server used now a days, you would have already configured apache many times by now but what about configuring it with SSL i.e. using apache to service on the https protocol, i assume you have already configured the basic apache server and have also enabled the SSL module, if not refer to my previous post on Configuring Apache Web server.
The following post is an extremely simplified step by step guide to configure SSL in apache using Self Signed Certificates you can also use a real certificate issued by a CA if you have it

We will use the openssl toolkit for generating a RSA Private Key and Certificate Signing Request, as the first step generate the key the command below will create a 1024bit key using 3des
