Dartmouth offers several central host computers for academic and research
computing needs.
Several communications programs — programs that let you connect your
personal computer to central computers and other services — are in use at
Dartmouth. Among the most popular programs are Dartmouth's own Fetch
(designed specifically for use at Dartmouth); AbsoluteFTP; FTP
Explorer; JellyFiSSH; SSH Secure,
and Secure CRT. These programs let you transfer files between
personal computers, most of the central computers, and many computers located
off campus. These, and other programs, are available on the Software
Downloads Web page.
JellyFiSSH, Secure CRT, and SSH Secure Shell are
Telnet applications that work for all ports on the Dartmouth computer network.
If you are using an Ethernet port, once the Telnet application is installed,
you simply start the program.
Fetch is a file transfer program (FTP) developed at Dartmouth that
allows you to transfer files between host computers and a Macintosh.
AbsoluteFTP, SSH Secure Shell, and FTP Explorer
are FTP programs that allow you to transfer files between host computers and a
Windows computer. These programs also allow you to retrieve files from archives
available on the Internet. File transfer is important if you need to use
another type of computer as a holding place for files (that is, to serve as
archives), or if you wish to share a file between compatible programs
on different types of computers.
The FTP window (see illustration above) displays a list of files on the
remote computer. Retrieving the file is usually as simple as double-clicking on
its name. It is simple to move files from your personal computer to the remote
computer (assuming you have an account on that remote computer) and to have the
files saved in a number of formats.
Dial-up Software
If you work off campus, you can use a modem connected to your computer and
your telephone line to dial in to the Dartmouth network or you can use the
connection from your Internet Service Provider and gain access to all services
just as if your personal computer was connected on campus. The Student
Computing Help Desk in 172 Carson Hall can provide specific information for
students; faculty and staff should contact their department's computing
support office for specific information. A variety of manuals and handouts
are also available in the Knowledge Library.
Tips for Using Communications Programs
If you have trouble with a communications program, the suggestions below
might help you identify what's wrong:
- Use a good network port and Ethernet cable to determine if the problem is
with the port, the cable, or your computer.
- If you're using a modem, plug a telephone into the outlet that the modem
was plugged into and dial the number by hand. You should hear a high-pitched
tone if everything is working correctly when the central computer
answers. This means your phone line is working. There may be software
configuration problems you should check. The problem could also be the cable
you're using.
- If the problem is the communications cable, you can obtain
a replacement at Computer Sales
and Service in 171 Carson Hall.
- If the problem is with your network port rather than with
your program or cable, go to the Wired
Network Service Request link and complete the form to get assistance,
call the Computing Help Desk at 646-2999 and select from the options provided
to report the problem, or contact your department's
computing support office. You will need to provide your room or office
number and the port number (the number on the wall jack). You will also need to
let them know how Computing Services can get in touch with you. The Computing
Help Desk will lead you through some troubleshooting, and, if necessary, they
will refer your problem to the Network Services technicians. If appropriate,
Network Services will need to make an appointment for you to let someone into
your room or office to make the repairs.
