(formerly known as "what")
This is a CLI utility for displaying current network utilization by process, connection and remote IP/hostname
How does it work?
bandwhich sniffs a given network interface and records IP packet size, cross referencing it with the
/proc filesystem on linux or
lsof on MacOS. It is responsive to the terminal window size, displaying less info if there is no room for it. It will also attempt to resolve ips to their host name in the background using reverse DNS on a best effort basis.
yay -S bandwhich
MacOS and other Linux flavours
cargo install bandwhich
If you're on linux, you could also get the generic binary from the releases.
Windows is not supported at the moment - if you'd like to contribute a windows port, it would be very much welcome.
USAGE: bandwhich [FLAGS] [OPTIONS] FLAGS: -h, --help Prints help information -n, --no-resolve Do not attempt to resolve IPs to their hostnames -r, --raw Machine friendlier output -V, --version Prints version information OPTIONS: -i, --interface <interface> The network interface to listen on, eg. eth0
Note that since
bandwhich sniffs network packets, it requires root privileges - so you might want to use it with (for example)
bandwhich also supports an easier-to-parse mode that can be piped or redirected to a file. For example, try:
bandwhich --raw | grep firefox
Contributions of any kind are very welcome. If you'd like a new feature (or found a bug), please open an issue or a PR.
To set up your development environment:
- Clone the project
cargo run, or if you prefer
cargo run -- -i <network interface name>(you can often find out the name with
iwconfig). You might need root privileges to run this application, so be sure to use (for example) sudo.
To run tests:
Note that at the moment the tests do not test the os layer (anything in the
