lubuntu 連接CISCO console

我的lubuntu電腦沒有RS232，所以使用USB轉RS232 接cisco console線連到CISCO的console
插上USB轉RS232後，用dmesg可看到新增一個/dev/ttyUSB0的裝置

安裝putty工具
$sudo apt-get install putty

啟動putty並設定ㄏconnection type為serial
serial line設為/dev/ttyUSB0
按Open出現
canot open /dev/ttyUSB0的錯誤訊息


檢查檔案是否存在
$ ls -al /dev/ttyUSB0
crw-rw---- 1 root dialout 188, 0  5月 14 18:34 /dev/ttyUSB0
只有root和dialout有權限執行
將自己的帳號(kitty)加入dialout froup
sudo adduser kitty dialout

重新登入電腦
再啟動putty就可以連上CISCO SWITCH了
