How to double ssh with vscode

To ssh into a remote station I do the following:

ssh -L 4001:connect.iop.kcl.ac.uk:4000 [email protected]

I'm then asked for a password which I enter, and I then do:

ssh -YX [email protected]

and am asked for another password, after which I am where I want to be.

I want to set this up in vs code using the Remote-SSH extension but am running into difficulty

When I try and add the first step (ssh -L 4001:connect.iop.kcl.ac.uk:4000 [email protected]), my config file looks as follows:

Host cana.iop.kcl.ac.uk
  HostName cana.iop.kcl.ac.uk
  LocalForward 4001:connect.iop.kcl.ac.uk:4000
  User dmzromc

But when I try and connect I get the following error:

[16:23:45.992] Log Level: 3

Any advice much appreciated

I had the same issue when forwarding a database port and fixed it by manually editing my ssh config as follows:

BEFORE (using the problematic config that VSCode auto generates)

Host mysshhost
  HostName mysshhost
  LocalForward 5432:mydatabaseservername:5432
  User myuserid

AFTER (works for me)

Host mysshhost
  HostName mysshhost
  LocalForward localhost:5432 mydatabaseservername:5432
  User myuserid

So in your case, the config should look something like:

Host cana.iop.kcl.ac.uk
  HostName cana.iop.kcl.ac.uk
  LocalForward localhost:4001 connect.iop.kcl.ac.uk:4000
  User dmzromc
