当 STunnel 作为服务运行时,无法连接到它

我已将 STunnel 配置为将非 SSL POP3 请求代理到端口 111 上的 GMail。当 STunnel 作为桌面应用程序运行时,此功能运行正常,但当我运行 STunnel 服务时,我无法连接到计算机上的端口 111(例如使用 Outlook Express)。

Stunnel 日志文件显示端口绑定成功,但始终看不到连接。当 STunnel 作为服务运行时,是否有东西阻止与该端口的连接?

这是 stunnel.conf

cert = stunnel.pem

; Some performance tunings  
socket = l:TCP_NODELAY=1  
socket = r:TCP_NODELAY=1  

; Some debugging stuff useful for troubleshooting  
debug = 7  
output = stunnel.log  

; Use it for client mode  
client = yes

; Service-level configuration

[gmail]  
accept = 127.0.0.1:111  
connect = pop.gmail.com:995

答案1

我在 W2003 x64 数据中心服务器(虚拟服务器)上遇到了同样的问题。关闭 Windows Firefall 并没有解决问题。有一件事让我感到疑惑:该服务没有出现在 services.msc - 列表中。

在将 service=stunnel 添加到 conf 文件后,它似乎可以工作了。

然后我重启了服务器,它又不工作了。我登录后,通过 services.msc 重启了服务,它又工作了。真是奇怪的事情。

答案2

尝试输入:

foreground = yes

在那里。
