Remote Connectivity

(Connecting from home or across platforms)



Connecting to either Unix or Linux environments is possible via ssh or any ssh-based client. Please note that non-ssh-based clients (like 'telnet') are no longer supported.

The ssh client comes standard on Linux and Mac OS systems. The recommended ssh-based client for Windows is PuTTY. PuTTY can be downloaded via the PuTTY download page: www.chiark.greenend.org.uk/~sgtatham/putty/download.html.


SSH overview:

Secure Shell (SSH) is a network protocol that allows data to be exchanged over a secure channel between two computers. Encryption provides confidentiality and integrity of data. SSH uses public-key cryptography to authenticate the remote computer and allow the remote computer to authenticate the user, if necessary.

SSH is typically used to log into a remote machine and execute commands, but it also supports tunneling, forwarding arbitrary TCP ports and X11 connections; it can transfer files using the associated SFTP or SCP protocols.

An SSH server, by default, listens on the standard TCP port 22.

An SSH client program is typically used for establishing connections to an SSHD daemon accepting remote connections. Both are commonly present on most modern operating systems, including Mac OS X, Linux, and BSDs.
