How can I connect to the dialups?

The primary method of connecting to the dialups is via a Secure Shell
(SSH) client.  SSH ensures that your password and login session are
encrypted.  You will need to authenticate to the SSH client, either by
providing Kerberos tickets or typing your password.

Note that the instructions here will simply get you a terminal (tty)
login session.  You will be able to run applications which normally
run entirely inside the "Terminal" window on an Athena workstation.
You will not be able to run programs that spawn other windows, such as
MATLAB, Evolution, Firefox, Acrobat Reader, etc.  For information on
running such programs on the dialups, please see our stock answer
entitled "How can I run X-Windows applications on the dialups?"

Connecting to the Athena Dialup servers from...

... another Athena workstation:

	athena% ssh athena.dialup.mit.edu

	You will probably not be prompted for your password, 
	as you likely have Kerberos tickets from your current 
	login session.

... a Windows machine:

	Visit http://web.mit.edu/software/ to download the
	SecureCRT ssh client.  It comes pre-configured with
	a profile called "Athena".  Simply double-click on it
	and enter your password when prompted.

... a Mac OS X machine:

	Open the "Terminal" application, which can be found
	in /Applications/Utilities.  At the terminal prompt,
	type:  ssh username@athena.dialup.mit.edu

		replace "username" with your Athena username

	If you have installed the MIT Kerberos Extras package,
	from http://web.mit.edu/software/ and have valid 
	Kerberos tickets, you will not be prompted for your password.

... a web browser:

	If you have a Java-enabled web browser, you can visit
	http://athena.dialup.mit.edu, where you can use a 
	Java SSH client to access the dialup servers.  This 
	method is particularly useful on workstations where you
	cannot install an SSH client.


The dialups also support access via Kerberized Telnet, though you are
encouraged to use ssh when possible.  From an Athena workstation, you
can simply type "telnet athena.dialup.mit.edu" at the athena% prompt.
From a Mac OS X machine running OS X 10.3 or higher, you can install
the MIT Kerberos Extras package, and then type "telnet -axF -l
username athena.dialup.mit.edu" in the Terminal, replacing "username"
with your Athena username.
