term_from_nat

=========================

connect a terminal inside a nat. used when you want somebody to help you, but he could not connect to your linux because your computer is inside a nat.

it is somehow like the ssh, the different is that:

the ssh is: client connect to server. do something in the server computer.

this term_from_nat is: client connect to server. do something in the client computer.

used when:

1 when you want somebody to do something in you linux computer
2 but he could not connect to your linux because your computer is inside a nat

how to use:

COMPUTER1(one nat):
1. pip install term_from_nat
2. python3 -m term_from_nat  or just type: term_from_nat
will show some tips:
client started, use: 
python3 -m term_from_nat -s -t  378885 
 to start the server
 
COMPUTER2(another nat):
1. pip install term_from_nat
2. python3 -m term_from_nat -s -t  378885   
     or just: term_from_nat -s -t  378885

that's all.

TBD:

1. windows support. currently only linux is supported as python pty package limit.
2. pty resize support. currently it uses the default pty columns x rows and not do a resize.
3. one stable mqtt broke.
4. mqtt auth support.

old/deprecated usage: normal usage uses a bridge to connect each-other. if you have a public ip server, then, you could run this, connect each other without bridge.

1. COMPUTER1: run python3 server_lite.py {server_port} on one computer that has a public ip.
2. COMPUTER2: run python3 client_lite.py {server_ip} {server_port} on the computer that inside a nat
3. COMPUTER1: type you command.
