 Redirecting standard output and using it to put that output to a file is 
 well-known and easy. Almost that easily any output can be redirected from
 one machine to another one. Say hello to ```nc``` utility.
 
 ```nc``` is part of netcat package which comes in two flavors in most of
 Linux distributions: ```nc-traditional``` and ```nc-openbsd```. In examples
 below I use -traditional.
 
 On the first machine start listening on some port:
 
 {% codeblock lang:bash %}
 $ nc -lp 12345 > ~/file_received
 {% endcodeblock %}
 
 Then, on another machine run something like this:
 
 {% codeblock lang:bash %}
 $ cat send_file | nc <hostname> 12345
 {% endcodeblock %}
 
 That's all. First machine starts listening on port 12345 and another machine 
 sends stream of data to that port. The communication isn't encrypted so for
 transmitting sensitive data use ```scp```.
