Next: Changing your Password Up: Quick Start Previous: Starting a Session
If you cannot physically be in the a computer laboratory, you may still be able to remotely login and start a session from a terminal or computer at some other location, such as an Instructional Technology Center (ITC) or from a home computer. In general, you will have to first gain access to a host with Internet access.
Once you have obtained access to a machine with an Internet connection, you can then securely connect into one of the laboratory workstations using one of the secure connetion programs like slogin or ssh.
To login to any C.S.G. workstation one MUST use a communications program that employs secure shell (SSH) encryption to establish a secure channel. Software programs such as the Secure Shell (SSH) utilities, which are available for just about every UNIX platform (Linux, Apple Mac OS X), or SecureCRT, a graphical user terminal program for Microsoft Windows (98 or higher).
Secure software can be downloaded from ITS Software Services. You will need your HawkID and password to download this software. If you are using a UNIX system that does NOT have SSH installed, then you can obtain a free implementation of a secure shell program from OpenSSH's web site. Pre-compiled binary packages are available for a number of UNIX operating systems; also available is the source code.To connect to the computer lab workstations, you will need to configure your SSH program to utilize the Secure Shell Protocol version 2 (SSH2). Please read your program's help files or manual pages (on UNIX) for assistance on how to do this.
Example using the ssh UNIX command-line utility:
slogin -l yourusername linux.cs.uiowa.edu
or
slogin yourusername@linux.cs.uiowa.edu
You can use slogin or ssh to login into one of these aliases (depending on department affiliation) to login:
| Access Group | Platform | Network Name |
|---|---|---|
| Anyone in CS or taking a CS course | Linux | linux.cs.uiowa.edu |
| CS faculty and grad students | Linux | linux.cs.uiowa.edu |
| CS users running large batch jobs | Linux | csbigjobs.cs.uiowa.edu |
| Anyone in Math or taking a Math course | Linux | linux.math.uiowa.edu |
| Math faculty and grad students | Linux | linux.math.uiowa.edu |
| Math users running large batch jobs | Linux | mathbigjobs.math.uiowa.edu |
| Anyone in Stat or taking a Stat course | Linux | linux.stat.uiowa.edu |
| Stat faculty and grad students | Linux | linux.stat.uiowa.edu |
| Stat users running large batch jobs | Linux | statbigjobs.stat.uiowa.edu |
| Anyone in Mathematical Sciences or taking a Mathematical Sciences course | Linux | linux.divms.uiowa.edu |
For names of specific workstations, consult the section Tables of Supported Equipment in the document Equipment and Software Available in Mathematical Sciences.
As of this writing, incoming telnet and rlogin interactive services have been disabled or removed from our workstations. You may still use those services for outbound connections from our workstations to other remote machines, but as those connection protocols send information in clear-text (or plain-text), they are considered HIGHLY insecure, and we strongly recommend not using them unless you absolutely must do so.
