The Basics - Connecting with Telnet or SSH

What is Telnet? What is SSH?

Telnet, in simple terms, is a terminal program that allows you to work on a machine other than your own. If you use Windows, you might consider it similar tong a DOS prompt on our machine, albeit using the Unix operating system once you get here.

SSH is a different protocol that works much the same way as Telnet, but it utilizes encryption to ensure that your password and all data sent and received during your session are kept safe. Both SSH 1 and 2 are supported.

Please note that if you have our FTP Account, you may access the server only through FTP. Telnet and SSH will not work for your account.

How do I get a Telnet/SSH client?

We strongly suggest using SSH rather than Telnet to ensure that your password and data are secure. There are plenty of good SSH clients out there and some of them free.

For Windows, we recommend:

PuTTY (Free)
SecureCRT

For Mac, we recommend:

Mac OS X Terminal (Free with Mac OS X operating system)
Fugu (Free Graphical SSH Application)

How do I use my Telnet/SSH client to connect to the server?

You'll first need to know the name of the server your account is on. A list of servers can be found on the server details page If you don't know which server your account is on, please e-mail support.

Once youyour Telnet/SSH client, you should find a menu option like "Connect", "Connection," or something similar. Select that and type in your server name. (In the screen shot below, calma.pair.com is just an example.) If it asks for a terminal type, use "VT100."

Next, you'll be prompted for your username and password. Once you correctly entered them, you'll be logged into the system. Below is a pre-connection screenshot from the default Windows Telnet client:

If you're using Telnet and it asks for a port, use 23. If your using SSH and you're required to do some additional configuration, use these settings:

Port: 22
Cipher: 3DES
Authentication: Password

Here is an example configuration with SecureCRT's connection dialog box:

If you are using a command-line style operating system like UNIX, or if you're using the Mac OS X Terminal, you would type:

telnet servername.pair.com
or...
ssh servername.pair.com

Replace "servername" with the name of the server your account is on.

How do I connect to the server via SSH (Secure Shell) using MAC OS X Tiger?

It is simple to connect to your Web server via a terminal window in MAC OS X Tiger by following the steps below:

a terminal window (found in the Utilities directory).
Enter ssh username You must replace "username" with your pair Networks username and replace "XXX" with your server name.
Enter your pair Networks password.

What commands can I use?

Now that you are logged on, you can use any of the UNIX commands to do what you need to do. (Please keep in mind that FTP level accounts do not come with Telnet access; if you have an FTP account and you connect, after changing the password you will be disconnected.)
