# LookAround "I want SSH into my laptop, but I keep forgetting its IP!!" _Has this ever happened to you?_ LookAround is a Rust program for looking up your computers' MAC and IP addresses within a LAN. There's no central server, so it's not a look-up, it's a look-around. ```text $ lookaround client Found 3 peers: 11:11:11:11:11:11 = 192.168.1.101:9040 # Your laptop 22:22:22:22:22:22 = 192.168.1.102:9040 # Your desktop 33:33:33:33:33:33 = 192.168.1.103:9040 # Your home server # Claimed MAC IP address ``` The LookAround client uses IP multicast to find LookAround servers within the same multicast domain. ## Installation Use the Cargo package manager from [Rust](https://rustup.rs/) to install LookAround. ```bash cargo install lookaround ``` To run the server as a normal user all the time, put this systemd unit in `~/.config/systemd/user/lookaround.service`: ```ini [Unit] Description=LookAround [Service] ExecStart=lookaround server [Install] WantedBy=default.target ``` Then start the service, check that it's running okay, and enable it for auto-start: ```bash systemctl --user start lookaround systemctl --user status lookaround systemctl --user enable lookaround ``` ## Usage Run the server manually: (If you haven't installed it with systemd yet) ```bash lookaround server ``` Run a client to ping all servers in the same multi-cast domain: ```bash lookaround client ``` ## Contributing Pull requests are welcome.
