A Hitch-Hiker's Guide to CSE
Welcome to CSE.
This guide aims to familiarise you with the ways things work around CSE.
Hopefully after reading it, you will have a better idea about things at CSE and at
least know where to get help.
This guide assumes you have had a look at the CSE UNIX Primer.
Where to find help
"Try to find the answer yourself before asking. You will avoid annoying people!"

How to connect to CSE and work from home
If you have access to a computer and an Internet connection at home,
you may (almost certainly) find that working from home is a lot more
convenient than coming into Uni every time to work on assignments and lab
exercises. Fortunately for you, connecting to Uni and working on a CSE
server is very easy if you have an internet connection.
Being able to transfer files between your home computer and your Uni
account is invaluable, and you can do it in two ways:
FTP (File Transfer Protocol)
You can transfer files using a ftp client. Both
UNIX/Linux and Windows have inbuilt FTP clients which you can invoke by typing
(in Windows, type in your Start->Run window):
Then, enter your user name and password.
You can then "put" files into your CSE account by using the command put:
This will put the file you specified in the current directory into your CSE account.
To "get" files from your CSE account, use the command get:
This will retrieve the file from the server and put it on your home computer.
To change the directory on your computer ("local change directory"), type:
To change the directory on your CSE account, type:
SCP (Secure Copy)
The major problem with FTP is that it doesn't use any form of encryption.
If this worries you, you can use SCP. Using SCP is simple once you get the
syntax right and makes copying things much easier. SCP is usually included
with Linux, so no extra programs are necessary. To use SCP on Windows,
you can use the program WinSCP available on this CD.
The syntax for scp is much the same as for cp, which you've used before to
copy a file.
For sending files:
scp <local filename> <username>@<server>:<remote filename>|
For retrieving files:
scp <username>@<server>:<remote filename> <local filename>|
scp foo.txt email@example.com:bar.txt|
will copy foo.txt to the file bar.txt in your CSE account. And,
scp firstname.lastname@example.org:bar.txt .|
will put bar.txt into your current directory at home (note '.' denotes
To transfer entire directories, use the -r (recursive) flag, for example:
scp -r email@example.com:dir1 .|
If you want to check your email or submit an assignment from home, you must
log in to a server and execute commands remotely.
To do this you can use Telnet or SSH (Secure Shell). Telnet, like FTP is
un-encrypted, and running GUI programs from it is also much harder than SSH. Here we
will discuss how to use SSH from Linux and Windows.
To SSH in Windows, you can use the program PuTTY, which can be found on
this CD. Simply double click on it, enter in the server name, choose the "ssh" radio button and click on connect. For a
list of CSE servers you can use, consult the primer. The most common are
wagner, weill and williams.
If you ssh into "login.cse.unsw.edu.au" without specifying a server, you will receive a random
To use SSH in Linux, at the command line type:
SSH has many flags, to find out more about ssh, please consult its man page
What you need to get you started
Your lecturer will tell you specific programs needed for your course,
however for most (first year) courses, you will need an editor and an
interpreter or compiler. Editors available on this CD are ConTEXT
and xemacs from cygwin.
To connect to CSE and work from home you need a ssh client and a ftp/scp
client if on Windows.
A small, nice easy to use ssh client is PuTTY , and an easy to use scp client
is WinSCP . Read instructions on how to use these above.
Updating and Getting new packages for Linux
To get the latest update for most of the packages on the CD, and to obtain new packages, you can try the sites below:
Additional Programs to use on CSE lab computers (stulocal)
Other than the standard programs that you can use straight away when you
log on to a CSE computer, you can also use a repository of student
maintained software. Software installed includes everything from an
assortment of IRC clients, ICQ, email tools, editors and many useful
development programs. To start using this software, you must add:
to a file in your home directory called ".profile". To do this just open
.profile in any editor (eg: nedit .profile) and add the line to it.
Make sure you include the dot and the space at the beginning of the line. Note that changes
to .profile will only take effect on subsequent logins.
You should also subscribe to either the stulocal.announce or stulocal.discuss
mailing lists to get the latest information about packages being installed.
To subscribe to any mailing list type:
mlalias -a <listname> $USER|
mlalias -a stulocal.announce $USER|

Other things available to you at CSE
Being a CSE student is about more than just assignments, exams and computer
Each year the two student societies, CSESoc and BINFSoc organise a variety of
activities, including a harbour cruise, free barbecues, a ski trip, code-fests,
install-fests and an end-of-year ball. CSE students are also organising a revue.
Check your email regularly for notices about these events as they are lots of fun.
Other student groups
Other student societies CSE students can participate in are IEEE, ACM and Women in Computing.
IEEE is the UNSW student chapter of the IEEE Computer Society. They organise about three activities per year, mostly full-day seminars by IEEE Distinguished Lecturers. For more information about IEEE Computer Society see www.computer.org.
ACM@UNSW is the UNSW Student Chapter for the Association for Computer Machinery (ACM). ACM@UNSW run a number of programming competitions which lead up to the ACM International Collegiate Programming Contest. For more information about ACM, see acm.org.
Support for women in CSE is available through the
