# what's a net cat?
* 解題
這題是純粹 nc 命令題,
可以參考先前的文 [Nice netcat...](https://hackmd.io/8iipVNdFR4anpjNdIQRsBg) 了解 nc 使用方法。
照題目的意思打上命令:
```shell
$ nc jupiter.challenges.picoctf.org 64287
```
連上伺服器後 flag 就跑出來了:
```shell
You're on your way to becoming the net cat master
picoCTF{nEtCat_Mast3ry_284be8f7}
```
