It provides a terminal UI showing which programs are using bandwidth in real-time.The tool is particularly useful for identifying bandwidth-heavy applications and monitoring network activity.
PARAMETERS
-i, --interface name
Monitor a specific network interface (may be repeated).-r, --raw
Output machine-friendly text instead of the interactive terminal UI.-n, --no-resolve
Do not resolve IP addresses to hostnames.-s, --show-dns
Show DNS queries in the output.-d, --dns-server ip
Use a custom DNS server for reverse lookups.-p, --processes
Show only the processes table.-c, --connections
Show only the connections table.-a, --addresses
Show only the remote addresses table.-t, --total-utilization
Show cumulative usage statistics rather than per-second rates.-u, --unit-family family
Unit format: bin-bytes, bin-bits, si-bytes, or si-bits.
FEATURES
- Real-time bandwidth monitoring- Per-process statistics- Connection details- Remote host identification- Interactive terminal UI- DNS query logging
INTERFACE
Display sections:- Processes - Bandwidth per process- Connections - Active connections- Remote addresses - Traffic by destination- Total - Aggregate statistics
INSTALL
CAVEATS
Requires root/sudo for packet capture. May not capture all traffic types. Hostname resolution can slow display. Terminal must support required features. Some VPN traffic may not be attributed correctly.
HISTORY
bandwhich was created by Aram Drevekenin around 2019 as a modern, user-friendly alternative to tools like iftop and nethogs. It is written in Rust and is currently in passive maintenance.
