SSH - Secure SHell

Secure SHell (SSH) is the safest way to establish your communications to
our servers with domain econ.uiuc.edu
(ysidro, ragnar, galton, s2, ...).
Your username and password are encrypted while in transit
through the network -- no longer plain text ready to be stolen.

You are used to establish your connection with telnet and ftp. From now
on, you should ONLY use SSH -- telnet service is not available any more.

Note: telnet and ftp to other sites is still available, though.

What do I need to do?


That depends on the OS you are using. Below are instruction pertaining to
Unix-based systems (includes Linux) and Windows.


Unix, Linux


You need to have some form of SSH installed in your system.
We use ssh, but there are other compatible secure shells out there, e.g., openssh.

To "ssh" unix-to-unix just type, for example:

ssh username@ragnar.econ.uiuc.edu
(note: you can drop the username@ if your local login is
the same as the remote)

To "ftp" use "scp"

From local to remote type, for example:

scp myfile.tex ragnar.econ.uiuc.edu:/hx/user/projects/
(please notice the colon)

From remote to local type, for example:

scp remote.machine:/hx/user/projects/myfile.tex myfile.tex

For more details see the man page, type man scp.

To X-display remotely

xhost is obsolete with ssh. ssh automatically encrypts X data.
Simply ssh to the remote machine and type the name of your
X program as you normally would.



 
 

Windows


If you use Windows, you can download the ssh programs from the webstore:

Webstore

You will be guided to the UIUC WWW identification service webpage.

Use your netid and password, log-in to the webstore site.

Then choose 'SSH 3.2.9 for Windows' from their lists of

available softwares. It is free of charge.

Install the SSH program in your PC.

Open your SSH, and type the name of machines you want to be connected.

(For example, ragnar.econ.uiuc.edu or ysidro.econ.uiuc.edu) also your netid.

And click 'connect' then you are ready to use ragnar / ysidro.

If you want to transfer files, open 'file transfer' terminal in your SSH program.

It is easy to use. Just click a file you want to copy, and drag it to the destination.
