sshocker: ssh + reverse sshfs + port forwarder, in Docker-like CLI

$ sshocker -p 8080:80 -v .:/mnt/sshfs [email protected]

• Forward connections to the port 8080 on the client to the port 80 on example.com
• Mount the current directory on the client as /mnt/sshfs on example.com

This is akin to docker run -p 8080:80 -v $(pwd):/mnt IMAGE, but sshocker is for remote hosts, not for containers.

Install

Download from https://github.com/lima-vm/sshocker/releases .

To download using curl:

curl -o sshocker --fail -L https://github.com/lima-vm/sshocker/releases/latest/download/sshocker-$(uname -s)-$(uname -m)
chmod +x sshocker

Tested on macOS client and Linux server. May not work on other environments, especially on Windows.

To use reverse sshfs, sshfs needs to be installed on the server (not on the client):

$ ssh [email protected] -- sudo apt-get install -y sshfs

Usage

Global flags:

• --debug=(true|false) (default: false): debug mode

Subcommand: run (default)

$ sshocker run -p 8080:80 -v .:/mnt/sshfs [email protected]

run can be omitted, e.g.

$ sshocker -p 8080:80 -v .:/mnt/sshfs [email protected]

Flags (similar to docker run flags):

• -v LOCALDIR:REMOTEDIR[:ro]: Mount a reverse SSHFS
• -p [[LOCALIP:]LOCALPORT:]REMOTEPORT: Expose a port
