最常见的原因是已经有一个Tor进程在运行。请检查您的进程列表，如果找到先前进程， 请将其停止。然后试试再运行Tor。
如果这个办法不管用，请检查 消息日志， 查看Tor是否显示有启动时的出错信息。
Vidalia无法与Tor连接的最常见原因是Tor启动后，遇到一个问题而导致立即退出。您可以通过检查您的消息日志，看看Tor是否记录了启动时遇到的问题。
如果Tor侦听的不是Vidalia希望的那个端口，当然Vidalia就无法连接到Tor。您一般不需要改变这个设置，但如果您机器另外运行的服务，与Tor的控制端口相冲突，这时您就需要重新制定一个不同的端口。您可以通过高级设置来改变原来的设定。
If Tor exits immediately after trying to start, you most likely have another Tor process already running. Check the message log to see if any of the last few messages in the list are highlighted in yellow and contain a message similar to the following:
connection_create_listener(): Could not bind to 127.0.0.1:9050: Address already in use. Is Tor already running?
If you find an error message like the one above, you will need to stop the other Tor process before starting a new one with Vidalia. On Windows, you would need to look for tor.exe in your Task Manager. On most other operating systems, the ps command can help you find the other Tor process.
If Tor had been running successfully for awhile (that is, longer than a few seconds), then you should check the message log for information about any errors Tor experienced before it exited. Such errors will be highlighted in either red or yellow.
如果Vidalia无法停止Tor，您可以检查消息日志，看看Tor试图退出时是否有错误报告。
