R-SSH

What can the program do?

This program allows you to quickly and safely forward local port without configuring the infrastructure.

Features:

1. Unique static subdomain based on public key fingerprint (md5).
2. Standard ssh clients are supported.
3. Supported http and https forwarding.
4. Automatic header correction for Host, Origin.
5. Supports X-Forwarded-For, X-Forwarded-Host, X-Forwarded-Proto.

What does it take to work?

1. SSH client.
2. Public key (for authorization).
3. Running r-ssh server

How to use?

Syntax

ssh -R [domain[+flags]:]<port>:target_domain:target_port <host>

domain - The domain to which requests will be redirected (Host and Origin headers will be replaced by this value if the corresponding flag is enabled) [optional].

flags - Flags change the logic of port forwarding. [optional]

Available flags:

1. s - redirect https
2. o - automatically fix Origin header (see domain)

port - Optional for r-ssh, but mandatory for ssh client. Affects only the link generated by r-ssh. By default, port 80 is not included in the link.

target_domain - Server to which requests will be redirected target_port - The port to which requests will be redirected

Examples

Forward local http://localhost:8080/ to web

ssh -R 80:localhost:8080 <host>

# forward "localhost:80" to "https://<fingeprint>.<host>/"

Forward https://example.com:443/ to web with automatic Host correction

ssh -R example.com+s:80:example.com:443 <host>

# forward "example.com+s:80" to "https://example_com-<fingeprint>.<host>/"

End-to-end example

Docker

Without ssl:

docker run -d --restart always --name rssh -p 22:22 -p 80:80 -e RSSH_HOST=<host> -e RSSH_HOST_KEY=/mnt/id_rsa -v /root/r-ssh/:/mnt pagran/r-ssh:latest

With ssl (wildcard certificate required):

docker run -d --restart always --name rssh -p 22:22 -p 80:80 -p 443:443 -e RSSH_HOST=<host> -e RSSH_HOST_KEY=/mnt/id_rsa -e RSSH_CERT_FILE=/mnt/<host>.cer -e RSSH_KEY_FILE=/mnt/<host>.key -v /root/.acme.sh/<host>/:/mnt pagran/r-ssh:latest
