This is a CLI utility for displaying current network utilization by process, connection and remote IP/hostname
bandwhichsniffs a given network interface and records IP packet size, cross referencing it with the
/procfilesystem on linux,
lsofon macOS, or using WinApi on windows. 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.
If you're on linux, you can download the generic binary from the releases.
pacman -S bandwhich
bandwhichis available in
nixpkgs, and can be installed, for example, with
nix-env -iA nixpkgs.bandwhich
xbps-install -S bandwhich
bandwhichis available in COPR, and can be installed via DNF:
sudo dnf copr enable atim/bandwhich -y && sudo dnf install bandwhich
brew install bandwhich
pkg install bandwhich
cd /usr/ports/net-mgmt/bandwhich && make install clean
bandwhichcan be installed using the Rust package manager, cargo. It might be in your distro repositories if you're on linux, or you can install it via rustup. You can find additional installation instructions here.
The minimum supported Rust version is 1.39.0.
cargo install bandwhich
~/.cargo/bin/bandwhichbut you need root priviliges to run
bandwhich. To fix that, there are a few options: - Give the executable elevated permissions:
sudo setcap cap_sys_ptrace,cap_dac_read_search,cap_net_raw,cap_net_admin+ep $(which bandwhich)- Run
sudo ~/.cargo/bin/bandwhichinstead of just
bandwhich- Create a symlink:
sudo ln -s ~/.cargo/bin/bandwhich /usr/local/bin/(or another path on root's PATH) - Set root's PATH to match your own:
sudo env "PATH=$PATH" bandwhich- Tell sudo to use your user's environment variables:
sudo -E bandwhich- Pass the desired target directory to cargo:
sudo cargo install bandwhich --root /usr/local/bin/
You might need to first install npcap for capturing packets on windows.
bandwhichon OpenWRT, you'll need to compile a binary that would fit its processor architecture. This might mean you would have to cross compile if, for example, you're working on an
x86_64and the OpenWRT is installed on an
arm7. Here is an example of cross compiling in this situation:
git clone https://github.com/imsnif/bandwhich
cargo install cross
cross build --target armv7-unknown-linux-musleabihf
target/armv7-unknown-linux-musleabihf/debug/bandwhichto the router using
scp bandwhich [email protected]:~/(here, 192.168.1.1 would be the IP address of your router).
USAGE: bandwhich [FLAGS] [OPTIONS]
FLAGS: -a, --addresses Show remote addresses table only -c, --connections Show connections table only -h, --help Prints help information -n, --no-resolve Do not attempt to resolve IPs to their hostnames -p, --processes Show processes table only -r, --raw Machine friendlier output -s, --show-dns Show DNS queries -t, --total-utilization Show total (cumulative) usages -V, --version Prints version information
OPTIONS: -i, --interface The network interface to listen on, eg. eth0
Note that since
bandwhichsniffs network packets, it requires root privileges - so you might want to use it with (for example)
On Linux, you can give the
bandwhichbinary a permanent capability to use the required privileges, so that you don't need to use
sudo setcap cap_sys_ptrace,cap_dac_read_search,cap_net_raw,cap_net_admin+ep `which bandwhich`
bandwhichcapability to list
/proc//fd/and resolve symlinks in that directory. It needs this capability to determine which opened port belongs to which process.
bandwhichcapability to capture packets on your system.
bandwhichalso supports an easier-to-parse mode that can be piped or redirected to a file. For example, try:
bandwhich --raw | grep firefox

To set up your development environment: 1. Clone the project 2.
cargo run, or if you prefer
cargo run -- -i(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.
