Introduction

This document describes how to connect to the UTS:IT UNIX servers. This can be done from a computer within the UTS:IT network, or from your home computer if you have the required software installed.

Student Servers

• rerun.it.uts.edu.au

NOTE: In order to log in to rerun.it.uts.edu.au, you need to use your UTS:IT account username, not your UTS student number. You can retrieve your UTS:IT username at https://start.it.uts.edu.au/reset. The password for this username is the same as your UTS email password.

NOTE: Throughout this document, replace username with your UTS:IT computer account username.

How to Connect to a UNIX server

The way in which you connect to a UNIX server depends on which Operating System you are using. The use of the following Operating Systems are described in this document:

• Windows
• Linux
• Mac OS X

(NOTE: With each method described here, NO special characters are printed to the screen when entering your password.)

Windows

To connect to one of the UTS:IT UNIX servers from a Windows computer, you will have to use a terminal emulation program. The one described in this document is PuTTY, a free SSH client. PuTTY will allow you to make a remote connection to a UNIX computer.

If you do not have the PuTTY program installed on your computer, you can go to the PuTTY Homepage and download a copy.

1. Open the PuTTY program. This will display the PuTTY Configuration window.
2. In the PuTTY Configuration window, enter the following information (replace server with the appropriate server as advised in the introduction):
   • Host Name (or IP address): rerun.it.uts.edu.au
   • Protocol: SSH (This changes the Port to 22)
3. Then click Open in the PuTTY Configuration window.
4. If you have never connected to the server from the computer you are using, you will be shown the PuTTY Security Alert window:
5. This will open the rerun.it.uts.edu.au PuTTY window.
6. You will now be connected to server.it.uts.edu.au, and be left with a prompt like the one below in the rerun.it.uts.edu.au PuTTY window.

Click Yes in the PuTTY Security Alert window.

When prompted, enter your current UTS:IT username and password.

Linux

To remotely connect to a UNIX server from Linux, you must use the Terminal to execute the ssh command.

ssh username@rerun.it.uts.edu.au

The authenticity of host 'server.it.uts.edu.au (138.25.xx.xx)' can't be established.
RSA key fingerprint is 4b:ee:c1:1e:7d:99:bc:dd:dc:4a:8e:d0:dd:62:bc:40.
Are you sure you want to continue connecting (yes/no)?

Type the full word yes (i.e. type the 3 letters 'y' 'e' 's' - entering 'y' only will not work) in the Terminal and press Enter.

username@rerun.it.uts.edu.au's password:

Type your current FIT password into the Terminal and press Enter.

rerun$

1. Right-Click anywhere in the main desktop area to display a menu, and select Open Terminal.
2. In the Terminal window, type the following command, then press Enter:
3. If you have never connected to the server from the computer you are using, you will be prompted with the following warning:
4. You will then be prompted to enter your password.
5. You will now be connected to server.it.uts.edu.au, and be left with a prompt like the one below in your Terminal.

Mac OS X

To remotely connect to a UNIX server from Mac OS X, you must use the Terminal to execute the ssh command.

1. From the Menu, select Go > Applications.
2. In the Applications window, Double-Click on the Utilities folder.
3. In the Utilities window, Double-Click on the Terminal icon. This will open the Terminal window.
4. In the Terminal window, type the following command (replace server with the appropriate server as advised in the introduction), then press Enter:
5. If you have never connected to the server from the computer you are using, you will be prompted with the following warning:
6. You will then be prompted to enter your current FIT password.
7. You will now be connected to server.it.uts.edu.au, and be left with a prompt like the one below in your Terminal.

ssh username@rerun.it.uts.edu.au

The authenticity of host 'server.it.uts.edu.au (138.25.xx.xx)' can't be established.
RSA key fingerprint is 4b:ee:c1:1e:7d:99:bc:dd:dc:4a:8e:d0:dd:62:bc:40.
Are you sure you want to continue connecting (yes/no)?

Type the full word yes (i.e. type the 3 letters 'y' 'e' 's' - entering 'y' only will not work) in the Terminal and press Enter.

username@rerun.it.uts.edu.au's password:

Type your current FIT password into the Terminal and press Enter.

How to Disconnect from a UNIX Server

After you have finished entering commands on the server, you should close your connection. To disconnect from the server, run the exit command:

rerun$ exit

This will log you out, and close your connection to the server.
