Password-less logins with OpenSSH
Posted by Steve on Fri 3 Jun 2005 at 09:45 Because OpenSSH allows you to run commands on remote systems, showing you the results directly, as well as just logging in to systems it's ideal for automating common tasks with shellscripts and cronjobs. One thing that you probably won't want is to do though is store the remote system's password in the script.
Pass on Passwords with scp
In this article, I show you how to use the scp (secure copy) command without needing to use passwords. I then show you how to use this command in two scripts. One script lets you copy a file to multiple Linux boxes on your network, and the other allows you to back up all of your Linux boxes easily. If you're a Linux sysadmin, you frequently need to copy files from one Linux box to another. Or, you may need to distribute a file to multiple boxes. You could use FTP, but using scp has many advantages.
Passwordless SSH
SSH concepts With remote access via ssh, there are 2 user accounts to consider : luser@local ---becomes---> ruser@remote Although both accounts can have the same account name (e.g. jdoe@local, jd@remote), and although ssh assumes that you will use the same username on both local and remote system, they are 2 distinctive user accounts, on separate machines.The second day I got the Palm Pre, I was able to SSH into my own Palm Pre and also make it into a WiFi Router. Of course, this is usual business for me as I manage about 30+ web servers on a daily basis. If I see a linux machine, the first thing I want to do is SSH into it. What is SSH?

SSH vs. VPN
VPN Definition An IP-based Virtual Private Network (VPN) provides a secure tunnel for transmitting data through an unsecured network such as the Internet. There are several protocols that can be used to achieve this such as PPTP, L2TP, L2F, IPSEC etc.
Setting up a reverse SSH tunnel
The TechRepublic CIO50 list celebrates the most influential and innovative tech chiefs, voted by their fellow CIOs SSH is an extremely useful tool in that it allows you to do many things in a secure fashion that you might not otherwise be able to do. One of the things SSH allows you to do is to set up a reverse encrypted tunnel for data transfer. Typically, when you initiate an SSH tunnel, you forward a port on the local machine to a remote machine which can allow you to connect to an insecure service in a secure way, such as POP3 or IMAP. However, you can also do the reverse.

Creating ssh reverse tunnel
Imagine you are out of the office, but you have an important document that you have to get from your personal computer in your office. Unfortunately your computer is protected behind a firewall, making it impossible to access. But you have a server that you can access and your personal computer also can access this server.

You can either transfer files to the remote machine from your local one, or vice versa. Usage is as simple as:
