use Cisco 7200 Simulator on Fedora 11 AMD 失敗...

OS: Fedora 11 32bit ( 2.6.30.5-43.fc11.i686.PAE )
CPU: AMD Athlon(tm) 64 X2 Dual Core Processor 4800+

Cisco 7200 Simulator

http://www.ipflow.utc.fr/index.php/Cisco_7200_Simulator

7200 , 3600　をサポートしているみたい。

ではダウンロードして使ってみよう。

dynamipsとdynagen をダウンロード。

http://sourceforge.net/projects/dyna-gen/files/

インストール

dynamips が IOS のシミュレータ、dynagen がトポロジーとか設定する役割という理解でいいのかな。。。

なんか、よくわからないいが、elf なんたらを適当にインストール。

だめだなー。
ん、dynamips が落ちた。。。

[1]+ 浮動小数点演算例外です /usr/bin/dynamips -H 7200 (wd: ~/cisco_works)

VMの CentOS で試してみるかなー。なんとなく感触はつかめたような。。
try again !!
