Lab Server#

Accessing the Lab Server#

The lab server is accessible in a manner similar to H4H.

Complete SSH instructions can be found here.

TLDR: SSH without password#

In your home directory, create a new key with the following command: 

ssh-keygen -t rsa -b 4096 -C "your_email@example.com"
Save the key in the default location (~/.ssh/id_rsa) by pressing Enter. Leave the passphrase empty to enable passwordless login.

To automatically add your public key to the ~/.ssh/authorized_keys file on the container 

ssh-copy-id -i ~/.ssh/id_rsa.pub -p <PORT> <USERNAME>@<HOSTNAME>
Enter the password to the container when prompted.

To create an alias for the server, add the following to your ~/.ssh/config file: 

Host labserver
    HostName <HOSTNAME>
    Port <PORT>
    User <USERNAME>
    IdentityFile ~/.ssh/id_rsa

You should now be able to SSH into the server without a password. 

ssh labserver

I can't see any files in the home directory#

This likely means the server was rebooted and the directory needs to be re-mounted.

To re-mount the home directory, run the following command:

sudo mount -a

If you are still having issues, please contact Jermiah Joseph or the lab coordinator.
