REmote CoMmanD Executor

recmd is a simple utility that can be used to execute command on a remote host.

Build

bash cargo build --release

For building using Docker or for static builds, see here

Usage

On the remote host where the command must be executed run recmd in server mode:

bash remcd srv -p 22000

with the command above recmd will listen on port 22000 (TCP) for incoming command requests.

For sending a command request, run recmd in send mode (change 1.2.3.4 with the IP address of the host where the server is running):

bash recmd snd -a 1.2.3.4 -p 22000 -c "bash -c 'ls /etc > /tmp/out'" recmd snd -a 1.2.3.4 -p 22000 -c "bash -c 'cat /tmp/out'"

Encryption Key

Communications between the client and the server are encrypted and authenticated with ChaCha20-Poly1305. recmd uses a static password (used to derive the 256 bits ChaCha20 key) defined in src/config.rs with the variable PASSWORD_DEF.

rust const PASSWORD_DEF: &str = "1e$tob5UtRi6oFr8jlYO";

Be sure to change the value of this variable with your own password before building your own recmd executable.
