"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 22:22:22:22:22:22 = 192.168.1.102:9040 33:33:33:33:33:33 = 192.168.1.103:9040 ```
The LookAround client uses IP multicast to find LookAround servers within the same multicast domain.
MAC addresses change slower than IP addresses, so if you know that
11:11:11:11:11:11 is your laptop, and your laptop is running LookAround,
LookAround will find the IP for you.
Use the Cargo package manager from Rust 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
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
Pull requests are welcome. This is a hobby project, so I may reject contributions that are too big to review.
