netproc(8)

Usage

netproc [-B] [-c] [-f [filename]] [-h] [-i iface] [-n] [{-p udp | tcp}] [-v] [--si]

Overview

netproc monitors network traffic and tries to find out which process this traffic belongs to, this is useful to quickly know who is consuming our network resources.

netproc currently supports the TCP and UDP protocols over the IPv4 protocol.

Options

-B, --bytes: view in bytes, default in bits

-c: visualization each active connection of the process

--color 1|2|3: color scheme, 1 is default

-f, --file "filename": save statistics in file, filename is optional, default is 'netproc.log'

-h, --help: show this message

-i, --interface iface: specifies an interface, default is all (except interface with network 127.0.0.0/8)

-n: numeric host and service, implicit '-c', try '-nh' to no translate only host or '-np' to not translate only service

-p, --protocol tcp|udp: specifies a protocol, the default is tcp and udp

--si: show SI format, with powers of 1000, default is IEC, with powers of 1024

-v, --verbose: verbose mode, also show process without traffic

-V, --version: show version

Running control

`arrow keys`	scroll
`s`	change column-based sort
`q`	exit

Examples

This command will display the ips / ports of the udp traffic of the processes, monitoring all available interfaces, except the loopback, and log a summary in the file "log.txt":

    # netproc -p udp -c -f "log.txt"

Useful to monitor the file generated in the above command:

    $ watch -t -d 'cat log.txt'
    $ watch -t 'cut -c -$COLUMNS log.txt'

Running whitout root:

    $ sudo setcap "cap_net_admin,cap_net_raw+pe" /usr/local/sbin/netproc
    $ export PATH=$PATH:/usr/local/sbin
