Connecting to SequAna' computational server: SequAna_Students

© 2024 Abdoallah Sharaf

We will perform much of our analyses on SequAna_Students's computational server that is creatively named 'SequAna_Students'.

To connect to SequAna_Students we will use ssh.

What is ssh?

To connect using ssh, we will use ssh-keys.

What are ssh-keys?

Exercise: Generate a pair of ssh-keys. Send the public key to the server. N.B. if working on Windows, try to use the Open SSH Client on the command line with the command: ssh-keygen. For both Windows and mac, the key should be saved to the default location which should be a hidden folder called .ssh inside your user's base directory.

Hint

ssh-copy-id bio16100@134.34.119.87

Exercise: ssh into the SequAna_Students server once Abdo has installed your SSH keys. Ask Abdo for SequAna's IP. (optional) set up a 'config' file in '.ssh' so that you don't have to enter your IP and username every time you want to

• I create an account for the course "bio16100" that we will share, with different access keys off course. You can access the server using:

ssh bio16100@134.34.119.87

Getting files in and out of the server

There will be many occasions where you want to either load files onto the server or take files off of their server.

We will cover that now.

The most common way to do this is using scp (secure copy).

scp [file] bio16100@134.34.119.87:
scp bio16100@134.34.119.87:[file] ./
