use netcat to transfer files between two machines

netcat is a very useful small program to communicate between two machines. If you just want to simply upload a file from one machine to another one, without setting up ftp, ssh server, then you can use netcat (it has many other functions).

commands:

1) listen on a port:

nc -l -p 2222 > log.txt

2) send file:

cat /etc/passwd  nc 192.168.0.50 2222
