In order to remotely login to cosmos, do the following:
Open a terminal on a UNIX system. If you do not have a UNIX system available, see below.
Type ifconfig and record your IP address. An
IP address has the form #.#.#.#, where each # is a number
between 0 and 254.
Type xhost +cosmos.colorado.edu. You should
get a response similar to "cosmos.colorado.edu being added
to access control list". If you don't, don't worry about
it, just continue on.
Type ssh -XY (yourname)@cosmos.colorado.edu,
where (yourname) should be replaced by your username, e.g.
ssh -XY firstname.lastname@example.org. Enter your
password when prompted. If you receive a strange
question about security, respond "yes".
To check whether you have access to graphics, attempt to load a graphical terminal, e.g. ds9.
Pray your internet connection is fast and you're set.
Remote Login for Windows
You can login remotely from windows using an ssh client, preferably
SSH Secure Shell,
but the graphics aren't trivial. I
will have to communicate with the CU IT department to find out if this
is possible, as it requires proprietary software. Please e-mail me if you'd like me to
do that, otherwise I'll skip it for now.
if this does not work! Most of this is
experimental for me, so if there's some failure in my
instructions, I may be able to correct it, but don't be
Login (ssh and scp) without a password
You can log in to a remote machine without a password using the following method:
Use ssh-keygen -r rsa to generate a key file (default is id_rsa) and store it in ~/.ssh/
Copy your key file to the remote computer ( scp ~/.ssh/id_rsa email@example.com:. )
Log in to the remote computer and append your key to ~/.ssh/authorized_keys , e.g.
cat id_rsa >> ~/.ssh/authorized_keys
