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.
That depends on the OS you are using. Below are instruction pertaining
to
Unix-based systems (includes Linux) and Windows.
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xhost is obsolete with ssh.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.
If you use Windows, you can download the ssh
programs from the 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.
