setting up ssh + git to work in spreadsheet on server

ssh

link to documentation on setting up ssh connection

• Remote login With password

ssh $remote_user@$remote_host

If the usernames on the local and the remote computer are identical, you can drop the $remote_user@-part and simply write

ssh $remote_host

• Remote login Using shared keys

To generate the key, use the program ssh-keygen as follows

ssh-keygen -t rsa

This program generates a pair of private/public keys in the directory ~/.ssh. The program first asks for the destination files for the keys, by default located in ~/.ssh. Afterwards a passphrase is requested.

Note: We recommend not to leave the passphrase empty. An attacker who gets hold of your private key can otherwise connect to the hosts where you deposited you public key since the passphrase is empty. Choose a long and complex passphrase.

You private key is id_rsa (don't give it to someone else), the public key is id_rsa.pub.

You copy your public key to a remote host with the command ssh-copy-id

ssh-copy-id -i ~/.ssh/id_rsa.pub $remote_user@$remote_host

Now you can connect simply to the remote host and the passphase is asked for. Once done, you get connected to the remote host. In case of a new connection the passphrase does not get asked for again during your entire session.

git

link to documentation of using git & ssh on server

To clone a Git repository over SSH, you can specify ssh:// URL like this:

$ git clone ssh://user@server/project.git

Or you can use the shorter scp-like syntax for SSH protocol:

$ git clone user@server:project.git
