Mr.2 可以幫你將本地的服務暴露到外網供訪問，支持 TCP/UDP, 當然也包括 HTTP.

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

示例

訪問局域網 HTTP 服務

$ 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 訪問本地機器

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

# then
$ ssh -oPort=5678 user@server_address

訪問本地 DNS 服務器

$ 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

通過 HTTP 訪問本地目錄：

$ 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
