我从程序管理器安装了stunnel4。当我试图在ubuntu 14或linux mint 17上运行stunnel时，我得到了下面的消息。我在centos6.5和macos x小牛上都有这个功能。不知道下一步该怎么做。重建openssl是一个烂摊子，如果这甚至是问题的话。

我的conf文件如下所示：

如果卸载存储库中的stunnel并将其替换为此stunnel：
https://launchpad.net/ubuntu/utopic/amd64/stunnel4/3:5.01-3
即使我禁用了压缩，我还是会得到。我不明白为什么它告诉我“服务[stunnel]：ssl服务器需要证书”，因为我试图只在客户端模式下使用它。另外，另一端不需要证书。

最佳答案
前几天我只是勉强过了这一关。
你想要的是Stunnel4_5.01-3_amd64.deb-你必须下载它-还没有在回购协议中。我相信有人用4.53成功了，但我没有做到。
https://launchpad.net/ubuntu/utopic/amd64/stunnel4/3:5.01-3
openssl 1.0.1f和libssl.1.0.0和libssl.1.0.0:i386 1.0.1f（它们是当前版本）很好。但请注意从您的开始输出：
使用OpenSSL 1.0.1e于2013年2月11日编译
使用OpenSSL 1.0.1f运行2014年1月6日
我认为更新上面描述的stunnel可以帮你解决这个问题。
你需要做的另一件事是关闭stunnel.conf中的压缩——我目前尝试的不同类型的压缩都不起作用。希望这是暂时的。
当做，
