Accessing Remote Computing Clusters using Open-SSH

General guidelines

You basically have three entities you want to interlink and provide bidirectional access.

1. Personal computer
2. Remote computer
3. Github or Gitlab a/c server

A copy of all my ssh keys is stored in ~/Dropbox/ssh-access-keys/

Known issues

• If the internet connection is not stable, the connection may be terminated abruptly, with an error message like:

Read from remote host ldas-pcdev12.ligo.caltech.edu: No route to host
Connection to ldas-pcdev12.ligo.caltech.edu closed.
client_loop: send disconnect: Broken pipe

Accessing LIGO Data Grid (LDG) CIT Cluster

To use ssh to push to github repo, you still have to provide in the username and password for your @git.ligo.org account. You have to make sure that your SSH public key for LDG-CIT is uploaded to the git.ligo.org account, and not your personal Github account.
