-
Setting up a UNIX account
-
Our UNIX accounts can be used for e-mail, personal web pages, and
general computing use. (See the sections below on where and how
to use your account.) Accounts are generally available to graduate
students and faculty; undergraduates must make special arrangements
(see us in person if this applies to you). To create a UNIX account,
please visit our office in RLM 7.126 and pick up a new user account
form. After filling out the form, you will need to have it signed
by your sponsor (your professor, your graduate advisor, or your
department chair). Once the form is signed and completed, bring it
back to RLM 7.126. Unless there is a problem with your form, we
will usually be able to set up your account within one business day
(often within about 15 minutes).
-
Logging in to Physics computers
-
The Graduate Physics Computer Lab is
located in RLM 9.326.
You can log in to any of the
Linux machines in the Grad Lab using your physics account login.
The Grad Lab is available 24 hours a day (except for special cases
such as University closure, severe weather, etc.).
-
Logging in remotely
-
You can connect to any of the general-purpose Physics machines
remotely via SSH. For security reasons, you cannot use TELNET
or FTP from outside of RLM (and you shouldn't even use these
tools within RLM; use
SSH/SCP
instead). Our systems support both SSH-1 and SSH-2; we recommend
using SSH2 if available.
-
The 15 general-purpose Linux machines that are available for login
are named (perhaps a bit unimaginatively) linux1.ph.utexas.edu
through linux15.ph.utexas.edu. There is also a remote
computational Linux machine named twist.ph.utexas.edu.
-
Additional information on the machines is available on the
Machine Info page.
-
Windows and Macintosh systems
-
If you need to use a Windows or Macintosh system, you should
visit the Physics Micro
Computer Lab (PMCL). The PMCL has several Windows and
Macintosh systems available for use; see
their home page
for information including lab hours and account information.
-
Printing to Physics Dept. printers
-
There are a number of public printers that can be accessed
through the Physics Dept. print server. We have help pages
with instructions on setting up a printer on
Mac OS X, Mac
OS 9, and Windows XP. If you need
help setting up a printer, please contact us and we will help you
get it working.
Security is always a concern when working in a networked computer
environment. Even if you do not feel that there is any security-sensitive
material stored under your account, you must always strive to keep your
account secure: The real danger lies in the possibility of an attacker
gaining access to your account, and subsequently using it to store files,
utilize restricted resources or services, or as a staging point for attacks
on other systems.
We have information available that explains the security measures that
are currently in place for
e-mail
accounts as well as for
remote
access to services. If you are having problems accesing your e-mail
or other services, or if you would like to learn how to access your account
securely from outside of RLM, please visit one of these links.
Users must also be aware of computer viruses, Trojan Horses, and other
such malicious programs. Anti-Virus software is available from the
Bevo Ware site.

e-mail security page.
