SSH is the protocol usually used to access the cluster. It allows access to a command line and optionally to run graphical programs on the cluster, with the GUI showing on your computer.
The first step in using the cluster is connecting. How to connect depends on your operating system.
First download PuTTY
Then fill the cluster IP address 139.124.148.56 followed by your username and password.
To make things faster when logging in, you can use the following tricks with SSH:
To avoid typing [email protected] all the time, you can add an entry to the
.ssh/config file (create the file if it doesn't exist):
Host cluster
HostName 139.124.148.56
User user
Now you simply type ssh cluster and bingo you're in.
Set up an SSH key if you don't already have one:
mycomputer $ ssh-keygen
......This will set up a private-public key pair.
Next, put the public key in the .ssh/authorized_keys file on the cluster.
mycomputer $ cat .ssh/id_rsa.pub | ssh [email protected] 'cat - >> ~/.ssh/authorized_keys'
<enter password>Now, ssh [email protected] should not require password.
NB: this is the same key you copy onto GitHub to automate access to your repositories there (if you use GitHub).
