2.1 Remote access

To gain CLI access remotely (via the Internet), you can use Telnet or SSH. Note that each requires a corresponding server module installed, enabled and configured on the accessed machine. In addition, each method requires a client program on the accessing machine.

Windows and Telnet. If the accessing machine is a Windows box, and you want to use telnet, you probably don't need to install anything. Create a CLI on the Windows box first. This can be done using the ``Start'' button, then ``run...'', followed by command for Win95, Win98, WinMe or cmd for WinNT, Win2k and WinXP. In the CLI (also called a DOS box), type the following:

telnet hostspec

Replace hostspec with the actual hostname or IP (Internet Protocol) address. For example, to access a host called ``power.arc.losrios.edu'', you can do the following:

telnet power.arc.losrios.edu

Windows and SSH. Windows does not come with an SSH client. You will need to download and install an SSH client program first. The most popular one is PuTTY (Pittsburg University TeleTYpe). Go to http://www.chiark.greenend.org.uk/~sgtatham/putty/ to download the latest version of PuTTY. Note that the file putty.exe is not an installer, it is the actual program. This is all you need!

Using PuTTY is easy. Refer to the ``FAQ'' and ``Docs'' links of the PuTTY home page. You still need to know the hostname (or IP address), your login name and your password to use it.
