+description: Send data between computers remotely

+---

+

+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```.
