## what
...is taking up my bandwidth?!
This is a CLI utility for displaying current network utilization by process, connection and remote IP/hostname
This is my first attempt at Rust. :)
### How does it work?
`what` sniffs a given network interface and records IP packet size, cross referencing it with the `/proc` filesystem. 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.
### Installation
At the moment, `what` is available through Cargo as a binary crate.
```
cargo install what
```
Important note: There is only support for linux at the moment, mostly because I don't have access to anything else. I'd very much welcome contributions, and would be happy to provide guidance. Open up an issue/pr if interested.
### Usage
```
USAGE:
what [FLAGS] --interface <interface>
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 `what` sniffs network packets, it requires root privileges - so you might want to use it with (for example) `sudo`.
### raw_mode
`what` also supports an easier-to-parse mode that can be piped or redirected to a file. For example, try:
```
what -i eth0 --raw | grep firefox
```
### Contributing
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.
