netproc - process-based network monitoring tool

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


        [--si]

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.

view in bytes, default in bits
visualization each active connection of the process
color scheme, 1 is default
save statistics in file, filename is optional, default is 'netproc.log'
show this message
specifies an interface, default is all (except interface with network 127.0.0.0/8)
numeric host and service, implicit '-c', try '-nh' to no translate only host or '-np' to not translate only service
specifies a protocol, the default is tcp and udp
show SI format, with powers of 1000, default is IEC, with powers of 1024
verbose mode, also show process without traffic
show version

scroll
change column-based sort
exit

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
