multi-hop ssh for remote development
Hi guys,
My python interpreter is on a machine which I have to do multi-hop ssh to login to. It has a local ip address and cannot be accessed from outside the local network. So I have to ssh to the gateway first and then ssh to my machine.
Anyone has any ideas how I can set up the remote interpreter in this scenario?
Thanks!
Edit: I have set up ssh forwarding and both ssh and sftp work without any problem. But in Pycharm I get the "Connection failed" error.

Hi guys,
Sorry for the long delay. I figured out the solution.
I needed to ssh to the machine through gateway with portforwarding port 22 of that machine any arbitrary port on localhost. So that if I ssh to localhost with the forwarded port, I can access the machine behind the gateway. Once the ssh is OK, in PyCharm I entered localhost with the port I used for forwarding and VIOLA!
PROBLEM SOLVED.
Hi Mehran Pesteie
Thank you for the solution. I have successfully set up the ssh as you described using following command.
ssh -l username -L 7777:work:22 gate cat -
and then in another shell when I executed the following command
ssh -p 7777 localhost
I can shh to my work machine directly.
But I do not understand the last bit of your solution. How can I now setup the PyCharm by entering localhost with port 22?
It does not work for me. Could you kindly guide me here.
Cheers!!

this solved it for me.
When you are on A and want to connect to server C through server B:
Here server C is the target machine and server B the gate machine. And then in the remote interpreter configuration(File>Setting>Projet>project interpreter>click on small wheel button>add remote):Apart from the general SSH tunnel setup (via `-L` key as stated above or `.ssh/config` with LocalForward), the issue could be due to quirks of sftp/scp. If in the shell config there is anything which has output - it hangs completely scp/sftp. So if ssh works fine for you, but scp doesn't - remove any non-standard lines from default ssh config (e.g. `bashrc`). Few examples are:
Feature Request: It would be really convenient if pycharm ( and perhaps other IntelliJ IDE's) could use the default ssh configuration file ($HOME/.ssh/config on most unix like enviornments) to connect to SSH hosts.
I have all my work hosts configured over there with the required port forwards, ssh-hops etc.
