# open-port-check-web
- https://www.yougetsignal.com/tools/open-ports/ 을 따라만들기, 클론 코딩
## 데모
[](https://www.youtube.com/watch?v=4IMSpyKuhL4)
## 기능
- 접속자의 공인아이피 알려줌
- 포트포워딩 테스트
- common ports 목록
- 모든 common port 테스트
## express generator로 프로젝트 생성
```
express findip-nodejs --view=ejs
```
## IPv4 방식으로 보기
```js bin/www
server.listen(port, '0.0.0.0');
```
```js routes/index.js
const ip = req.headers['x-forwarded-for'] || req.connection.remoteAddress;
console.log(ip);
res.render('index', { title: 'findip', ip: ip });
```
- ip를 index view에 렌더링하여 보냄
## is-port-reachable
```js routes/index.js
const isPortReachable = require('is-port-reachable');
result = await isPortReachable(port, { host: ip });
```
- is-port-reachable 패키지를 사용해 포트 오픈 여부를 알아온다
- 당연한 말이지만 해당 포트를 리슨 하는 서버가 존재해야 한다
- host는 domain을 적어도 되고, ip로 적어도 된다.
## check all common ports
```js routes/index.js
const common_ports_list = [
[21, 'FTP'],
[22, 'SSH'],
[23, 'TELNET'],
[25, 'SMTP'],
[53, 'DNS'],
[80, 'HTTP'],
[110, 'POP3'],
[115, 'SFTP'],
[135, 'RPC'],
[139, 'NetBIOS'],
[143, 'IMAP'],
[194, 'IRC'],
[443, 'SSL'],
[445, 'SMB'],
[1433, 'MSSQL'],
[3306, 'MySQL'],
[3389, 'Remote Desktop'],
[5632, 'PCAnywhere'],
[5900, 'VNC'],
[25565, 'Minecraft'],
[3000, 'node express'],
[5500, 'vscode live server'],
];
router.get('/checkAll', async function (req, res) {
console.log(req.query);
const { ip } = req.query;
let result = [];
const reqPromiseArray = [];
for (const item of common_ports_list) {
const port = item[0];
reqPromiseArray.push(isPortReachable(port, { host: ip }));
}
// result = await isPortReachable(port);
result = await Promise.all(reqPromiseArray).then((promiseResult) => {
return promiseResult.map((isOpen, idx) => {
return {
isOpen: isOpen,
port: common_ports_list[idx][0],
port_name: common_ports_list[idx][1],
};
});
});
res.json({ result: result, req: req.query });
});
```
- req로부터 ip를 가져오고,
- common_ports_list의 port를 가져와서 프로미스를 생성한다
- `await Promise.all(reqPromiseArray)`로 요청을 병렬 처리하였다
