Show HN: Mr2, Expose local server to external network

## What is Mr.2

Mr.2 can help you expose local server to external network. Support both TCP/UDP, of course support HTTP.<br/> Keep it simple, stupid.

### Server

``` $ mr2 server -l :9999 -p password ```

### Client

``` # Local server is 127.0.0.1:1234, expect to expose: server_address:5678 $ mr2 client -s server_address:port -p password -P 5678 -c 127.0.0.1:1234 ```

``` # Local web root is /path/to/www, expect to expose: server_address:5678 $ mr2 client -s server_address:port -p password -P 5678 --clientDiretory /path/to/www ```

### Example

#### Access local HTTP server

``` $ mr2 client -s server_address:port -p password -P 5678 -c 127.0.0.1:8080

# then Your HTTP server in external network is: server_address:5678 ```

#### SSH into local computer

``` $ mr2 client -s server_address:port -p password -P 5678 -c 127.0.0.1:22

# then $ ssh -oPort=5678 user@server_address ```

#### Access local DNS server

``` $ mr2 client -s server_address:port -p password -P 5678 -c 127.0.0.1:53

# then Your DNS server in external network is: server_address:5678

$ dig github.com @server_address -p 5678 ```

#### Access your local directory via HTTP

``` $ mr2 client -s server_address:port -p password -P 5678 --clientDirectory /path/to/www

# then A HTTP server in external network is: server_address:5678 ```

#### Any TCP-based/UDP-based ideas you think of
