爲什麼不是「lsof」告訴我正在運行的進程的PID？

Question

我在Mac Sierra上。我想開始我的Tor的實例，但顯然它已經在我的電腦上運行...

localhost:myproject davea$ tor --CookieAuthentication 0 --HashedControlPassword "" --ControlPort 9050 --SocksPort 50001 
Nov 12 12:27:06.777 [notice] Tor v0.2.8.9 running on Darwin with Libevent 2.0.22-stable, OpenSSL 1.0.2j and Zlib 1.2.8.

我累找出PID是在指定的端口上運行的過程中有什麼，但蘋果告訴我什麼...

localhost:myproject davea$ 
localhost:myproject davea$ 
localhost:myproject davea$ lsof -i :9050 
localhost:myproject davea$ 
localhost:myproject davea$ lsof -i :50001 
localhost:myproject davea$ netstat -anp tcp | grep 50001 
localhost:myproject davea$ netstat -anp tcp | grep 9050 
localhost:myproject davea$ 
localhost:myproject davea$ 

任何想法如何我可以找出什麼是PID和殺死它，所以我可以啓動Tor？

Answer 1

要找出PID使用特定端口：

$ lsof -t -i :9050 

命令你已經表明是正確的，那麼你可能要確認是否lsof和netstat做一個更實際的工作通用命令作爲測試，例如：

$ lsof -i 

如果仍然不返回任何內容，那麼你就會知道問題不是孤立的。根據您的用戶權限，您可能需要使用sudo執行lsof或netstat：

$ sudo lsof -i -P 

還有的可能性也不返回任何東西，因爲端口可能沒有真正打開：

Nov 12 12:27:06.783 [notice] Opening Control listener on 127.0.0.1:9050

關閉部分 - 構建127.0.0.1:9050控制監聽器

確認是否或者不是tor過程實際上是按照通知運行的：

$ ps ax | grep tor
