Unix Instructions

(These apply to the eco220ta account and to accounts on my computer)

Installing software:

You will need two useful pieces of software both free for academic use.

Putty

(a secure telnet program (ssh) good for working in unix and emacs)

To download go to:

http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html

Then download putty.exe

In putty always select ssh (not telnet) Under host name, put for example eco220ta@chass.utoronto.ca

SSH Communications Security

Also a secure telnet/ftp program. This is less good for emacs editing but better for copy and pasting back and forth between emacs and windows applications. It also particularly good for file transfers.

This can be obtained on the internet at

ftp://ftp.ssh.com/pub/ssh/

Download SSHSecureShellClient-3.2.3.exe

or the latest version that looks like this and ends in .exe.

(Note: In case the location changess go to the home page located at http://www.ssh.com/ Then click on products, Then SSH Secure Shell for Workstations Then under non commercial downloads click on SSH Secure Shell for Workstations 3.2)

To use ssh: double click on the install icon You now have 2 program icons the yellow one is a secure ftp program it allows you to move files back and forth the grey one is a secure telnet (ssh) program. In either case just open, chose quick connect enter chass.utoronto.ca under host enter eco220ta under user
