 # socks5-ssh-proxy
 
-If HTTP(s) is filtered and outbound SSH is allowed, just create a SOCKS5 proxy. Beat the sensorship, and be free!
+If HTTP(s) is filtered and outbound SSH is allowed, just create a SOCKS5 proxy over SSH using a [Jump server](https://en.wikipedia.org/wiki/Jump_server). Beat the (corporate) sensorship, and be free!
+
+## Background information
+
+The proxy can use [SSHFP DNS record](https://en.wikipedia.org/wiki/SSHFP_record) verification for extra protection so the SSH host public key is side-channel checked.
+
+The `release` build target is fully silent as `os.stdout` and `os.stderr` is written to `/dev/null`. Also it embeds the configuration to the SSH jump host (see `config_template.go` copied to `config_release.go`).
 
 ## Server installation
 
-For SSHFP check:
+When using OpenSSH server a special `tunnel` user should be created. It must configured no PTY could be created (interactive mode). So the client is unable to execute commands on the SSH jump host.
 
-- Create SSHFP DNS records use `ssh-keygen -r` on the server
-- Configure DNS server with those records
+### `/etc/ssh/sshd_config`
+
+The following OpenSSH daemon options could be set. This by default doesn't allow anyone to login except from users from the system group `ssh`. It immediate drops the connection instead of sending a response. The system `tunnel` user needs to set `PermitTTY no` so no shell is possible, only TCP forwarding.
+
+```
+PermitRootLogin no
+PasswordAuthentication no
+MaxAuthTries 0
+ChallengeResponseAuthentication no
+
+Match Group ssh
+	MaxAuthTries 3 # Only key-based may be tried
+
+Match User tunnel
+	MaxAuthTries 1 # Only key-based may be tried
+	GatewayPorts yes
+	AllowTcpForwarding yes
+	PermitTTY no
+	PasswordAuthentication no
+```
+
+### SSHFP verification
+
+- Create SSHFP DNS records use `ssh-keygen -r` on the SSH jumphost server
+- Configure (public) DNS server with those records
 - Check if records are active with `dig SSHFP <hostname> +short`
