To make it easier to connect to the remote machine in the future, you can create or edit your ssh config file in  ~/.ssh/config. This file allows you to specify connection settings and aliases for different remote machines. To create an ssh config file, open the ~/.ssh/config file in a text editor and enter the following information, replacing user_id with your username on the remote machine:

Host crc
    User user_id
    HostName gw.crc.rice.edu
    IdentityFile ~/.ssh/id_rsa

Host aries
    User user_id
    HostName aries.rice.edu
    ProxyJump crc
    Port 22
    IdentityFile ~/.ssh/id_rsa

Host nots

    HostName nots.rice.edu
    ProxyJump crc
    Port 22
