Missing support for remote GDB via intermediate remote server

[illegal-instruction]

I'm trying to use the extension to debug some C code in a remote server. That server is defined in my .ssh/config as 'gdb_server' and is accessed via an intermediate remote server:

Host gdb_server
 Hostname xxx.yyy.zz.aa
 Port 2038
 User <someuser>
 ServerAliveInterval 60
 ProxyCommand ssh <intermediate_user>@<intermediate.server.com> nc %h %p %r

If I use this configuration:

 "ssh": {
   "host": "gdb_server",
   "cwd": "<app_root_path@remote_server>",
   "keyfile": "/home/(omitted)/.ssh/id_rsa",
    "user": "<intermediate_user>",
    "port": 2038,
    "bootstrap": "<some scripts>"
}

I get the following error:

Could not run gdb over ssh!
Error: getaddrinfo ENOTFOUND  gdb_server:2038

Using the 'port' to '22' returns the same error.

Couldn't find any other parameter to configure this kind of 'intermediate-ssh' setup. In other cases, I've been able to use the extension to debug in a server accessible from my computer without any issue.

I guess the idea should be (I have no idea how the extension works internally so I don't know how hard it is), to enable the support of 'ssh/config named configurations', like gdb_server in this example.

Thanks for your time,
C

P.D: In any case this extension is awesome!

the extension is using the https://www.npmjs.com/package/ssh2 library which is a pure JS implementation of SSH and doens't support loading that ssh/config file. So instead it would be necessary to load and parse the ssh config for the current user with all ssh options which we want to support considered.

@WebFreak001 : Can you please add the socksv5 to support remote GDB via intermediate remote server ?
as described here : https://www.npmjs.com/package/ssh2#dynamic-11-port-forwarding-using-a-socksv5-proxy-using-socksv5-

I changed the code, instead of using ssh, I used ssh-promise, and It's working

@mohamedchebbii That is great. It would be possible for you to share your modified code or create a pull request that could help @WebFreak001 bringing this, if possible, into the extension?

Thanks both of you for your work!
