Setup

During the setup of Tsuka, the ssh server is setup by installing openssh-server and setting up the password as the root password for Tsuka. PermitRootLogin yes is added to /etc/ssh/sshd_config. The ssh server is started as a daemon process.

Connection

For accessing the master pod, the team has to be connected to Katana’s VPN. The team can then ssh into their master pod using the following command:

ssh root@<team-ip>

The team can then enter the password provided to them in teamcreds.txt to access their master pod.
