UNIX, Linux, SSH, Telnet, X Windows and FTP
This page describes the different programs you can use to connect to the UNIX systems at Boston University. For more information about UNIX, please see the Central Consulting site.
Using the VPN with Linux
Please see our VPN page for the instructions you'll need to set up a Linux client that works with our VPN.
File Transfer Protocol (FTP)
Learn how to install, configure and use FTP clients with your BU account(s) and Web site(s).
PuTTY for Windows (SSH)
Use PuTTy to make an SSH connection to Boston University's ACS cluster or any other UNIX machine that supports SSH. One you have made the SSH connection, you can use UNIX commands and you can read mail using Pine.
CRT 2.4 for Windows (Telnet)
Use CRT to access UNIX machines that don't support SSH. SSH gives you a more secure connection than Telnet; we recommend you use SSH if your host computer supports it.
Macintosh SSH and Telnet Clients
Learn how to use our supported Mac clients: the OS X versions of SSH and Telnet, as well as NiftyTelnet SSH and BetterTelnet for OS 9.
X-Win32 for Windows
Configure X-Win32 to make a remote X Windows connection to Boston University's ACS cluster or any other UNIX machine. X Windows lets you run graphical programs on ACS, such as SAS or Mathematica. (If you need to do this when you are using another Internet Service Provider, see these instructions instead.)
X Windows for Mac OS X
You can use the X Windows client for Mac OS X to make a remote X Windows connection to Boston University's ACS cluster or any other UNIX machine. X Windows lets you run graphical programs on ACS, such as SAS or Mathematica.
BU Linux
If you have a PC and want UNIX as an operating environment on your own computer, you can download BU Linux in addition to, or as an adjunct to Windows. (If you run Mac OS X, you already have UNIX on your computer.)
