Non-HTTP protocols

[musahi0128]

Hi, I am trying to expose my ssh port through your service. I use this command on my server

~/Downloads# ssh srv.us -R 1:localhost:22
The authenticity of host 'srv.us (5.161.108.112)' can't be established.
ED25519 key fingerprint is SHA256:oG4TmU4TFvLkEOWN80+x+ITOMfFRyusJ1IC7ZBYAKTM.
This key is not known by any other names
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
Warning: Permanently added 'srv.us' (ED25519) to the list of known hosts.
1: https://uvlkreaxmsbbc6gcwnkeknk6eu.srv.us/

I then tried ssh to the provided https address

C:\Users\User1>ssh -i .ssh\id_rsa uvlkreaxmsbbc6gcwnkeknk6eu.srv.us -p 22
Usage: ssh srv.us -R 1:localhost:3000 -R 2:192.168.0.1:80 …
Connection to uvlkreaxmsbbc6gcwnkeknk6eu.srv.us closed.

it goes straight to exit as shown above. Can you please give example for the usage I tried? akin to SSH jump server I guess. Thanks!

We still wrap all services in TLS (SSL), so for protocols that do not support it, you'll need to use something like stunnel.

For example:

$ cat config.stunnel
foreground = yes
[ssh]
client = yes
accept = 22222
connect = pcarrier.gh.srv.us:443
$ stunnel config.stunnel
2023.08.24 22:22:41 LOG5[ui]: stunnel 5.70 on aarch64-apple-darwin22.4.0 platform

[…]

then while stunnel is running,

$ ssh localhost -p 22222

It works, thanks!
