How Do I Log Into Eniac?

At times it becomes necessary to administer your eniac account from the unix command line. To access this interface, you must connect through one of several methods listed below.

From the Lab:

Windows:

Once logged onto a CETS lab computer, double-click on the "Connect to Eniac" icon if using a Windows NT computer, or "eniac" if using a Windows 2000 machine. Log on with your user name and password. Your user name is the first part of your email address, i.e. username@seas.upenn.edu.

For additional help in the labs, visit one of the CETS help desks located in Towne M70 or Levine Room 164, or search for your specific question in the Answers technical support engine. Once you are finished exploring the unix environment, type "exit" to log out.

WARNING: Closing the session while a program is running in the unix environment can lead to lost data. Try to use "exit" whenever possible.

Linux or Unix:

To open a secure connection to Eniac from a Linux or Unix computer, open a console (xterm) window and enter

% ssh user@eniac.seas.upenn.edu

For detailed information on using ssh, see "What is SSH?"

From home:

SecureCRT (Recommended)

Van Dyke Technologies' SecureCRT is a secure SSH and telnet client provided for free to all Penn students and faculty by ISC. To download the client, visit http://www.upenn.edu/computing/product/net/securecrt.html. After installing the client, follow these steps to connect to eniac:

1. Double-click on the SecureCRT icon on the desktop.
2. When the program opens, a list of hosts will be presented. Double-click on "eniac.seas.upenn.edu".
3. The first time you connect to a server, a dialogue box will appear asking whether or not you would like to accept the new host key. Click on the button marked "Accept & Save".
4. Enter your user name and password when prompted. Your username is the first part of your email address, i.e. username@seas.upenn.edu.

These instructions will place you at the unix command prompt. When you're finished, you can exit SecureCRT by simply typing "exit".

WARNING: Closing the session while a program is running in the unix environment can lead to lost data. Try to use "exit" whenever possible.

Telnet

Telnet (except kerberized telnet) is prohibited on most of the servers CETS runs.
