Voltron是macOS下lldb的一個外掛，在使用的時候會遇到諸多的問題。

在lldb filename檔案時，其中之一的log：

➜  lldb cmdshellcode
An error occurred while loading Voltron:

Please ensure Voltron is installed correctly per the documentation: https://github.com/snare/voltron/wiki/Installation
(lldb) target create "cmdshellcode"
Current executable set to 'cmdshellcode' (x86_64).
 

Voltron預設配置使用5555埠進行RPC通訊，找到相應的port，kill即可。

➜  lsof -i:5555
COMMAND  PID     USER   FD   TYPE             DEVICE SIZE/OFF NODE NAME
lldb    2739 username    5u  IPv4 0xc79083f2b460cbbd      0t0  TCP localhost:personal-agent (LISTEN)
➜  kill 2739
