unameで調べる
OSのカーネルは、unameに-aオプションを付けて調べることができます。
[user@myserver ~]$ uname -a
Linux myserver 2.6.18-274.7.1.el5xen #1 SMP Thu Oct 20 17:06:34 EDT 2011 x86_64 x86_64 x86_64 GNU/Linux
Linux myserver 2.6.18-274.7.1.el5xen #1 SMP Thu Oct 20 17:06:34 EDT 2011 x86_64 x86_64 x86_64 GNU/Linux
nmapで調べる
もう一つ、nmapを使う方法もあります。
nmapはポートスキャン用のコマンドですが、これでマシンのOSを調べることができます。
OS調査オプションの-Oを付けることによって、OSを調査します。
ただし、これはあくまで「調査」して推測するコマンドなので、100％正しいバージョンが分かるわけではありません。
そのかわり、外部サーバーに対して実行することもできます。
[root@myserver ~]# nmap -O myserver

と出ました。
nmapコマンドは、/usr/share/nmap/nmap-os-db の中からTCP/IP fingerprintをもとに推測を行ないます。
command not found の場合は yum install nmp で事前にnmpをインストールします。
Examples of Aphorism in Literature
This quote originated from Thomas Howell in New Sonnets and Pretty Pamphlets.
If you can do something, then you need to do it for the good of others.
Like George Washington, Sandys believed that telling the truth is always the way to go.
People often use this quote when discussing health, but Franklin was talking about fire safety.
Now you might be asking.
Ready to Use These Aphorism Examples In Your Writing.
Aphorisms are so common that we hardly think twice about them.
