PyCharm: Configuring multi-hop remote Interpreters via SSH
Question:
To connect to the computer at my office I need to run ssh twice. First to connect to the host-1 and then from host-1 to host-2 and each one has different credentials. However the configuration menu in Pycharm only accepts one ssh tunnel.
Configure Remote Python Interpreter dialog box
Is there any way to set a multi-hop ssh to have access to the interpreter and data files on the host from local?
Answers:
You can use port forwarding on ssh.
1. Open a terminal and run:
On your local system:
ssh -L 6000:<target_server_ip>:22 <proxy_server_user>@<proxy_server_ip>
You should be connected to the proxy now. You can substitute 6000 with any port.
2. (optional) Test
Now you can ssh into the target server on another terminal with:
ssh -p 6000 <target_server_user>@localhost
3. Configure PyCharm
Keep in mind not to close the first terminal!
The same goes for the PyCharm. Just set the remote interpreter connection through ssh with the following configuration:
- host: localhost
- port: 6000
- user: target_server_user
PyCharm seemingly parses the local .ssh/config too.
If you already have configured ssh hopping there, you can just specify the target server in your pycharm ssh-config.
~/.ssh/config (source)
Host bastion
Hostname bastion.domain.com
Port 2222 # a non-standard port is a good idea

Host servera
Hostname servera.lan.local
User servera-user
ProxyCommand ssh bastion -W %h:%p
in pycharm:
Host servera, User name server-user
For users on ssh version 7.3 or later this can be simplified using the ProxyJump parameter.

User bastion-user
