Listen on a network port and save data to a text f

问题:

Is there some easy way in linux to listen for data on network and save them to a text file?

Thank you.

Netcat is your friend here.

nc -l localhost 10000 > log.txt

Netcat will listen for a connection on port 10000, redirect anything received to log.txt.

Also available is TCPDump.

sudo tcpdump -i eth0 -vvvvtttAXns 1500 'port 10000'

Other tools are Ethereal (man page) or Wireshark and it's console variant tshark.

In any case please be aware that you are following local and company rules.
