问题描述
我有一个ruby客户端，使用IMAP& SSL。我使用Ruby Net :: IMAP库（其中使用openssl）来连接。它已经工作好几个月了。交换服务器管理员从godaddy安装新的证书现在我得到这个错误：
SSL_connect SYSCALL返回= 5 errno = 0状态= SSLv2 / v3读取服务器hello A
有人知道这个错误是什么意思？ （我试过谷歌搜索）
我怀疑有新的证书导致这个问题，但我不知道如何解决它。
此外，我知道您可以在使用NET：HTTP时禁用证书验证：
http.verify_mode = OpenSSL :: SSL :: VERIFY_NONE如果http.use_ssl？
但我不知道如何使用NET：IMAP。我想禁用这个，看看这是否是问题。
至于代码im使用：
Im使用此（或非常接近此） p>
我尝试更改为：
@connection = Net :: IMAP.new（@server，@port，@ssl，nil，false）
这里是stacktrace

原来这个问题的根本原因是ms交换错误配置。我很想知道更多关于ssl错误和如何troublshoot他们，但我只是没有得到这方面的很多信息。
我试图只是troublshoot这使用open ssl，fyi，你可以这样做：
OpenSSL> s_client -connect myserver：993
当它被破坏时，我收到这个错误：
CONNECTED （00000003）
26831：错误：140790E5：SSL例程：SSL23_WRITE：ssl握手
失败：s23_lib.c：188：
我得到了一个证书和握手消息等。
这是我的交换管理员说，他做了：我只是去了IMAP协议，进入访问标签，然后证书按钮，从那里我选择了替换证书并选择新的证书。
I have a ruby client that connects to an exchange server using IMAP & SSL. I use the Ruby Net::IMAP library (which uses openssl under the covers) to connect. Its been working fine for months. The exchange server admin installed new cert from godaddy and now I get this error:
SSL_connect SYSCALL returned=5 errno=0 state=SSLv2/v3 read server hello A
Does anyone know what this error means? (I tried googling)
I suspect there is an issue with the new cert causing this, but I dont know how to troubleshoot it.
Also I know you can disable certificate verification when using NET:HTTP by doing:
http.verify_mode = OpenSSL::SSL::VERIFY_NONE if http.use_ssl?
but I cant figure out how to do this using NET:IMAP. I want to disable this to see if this is the problem.
As for code im using:Im using this(or very close to this) http://github.com/look/fetcher/blob/master/lib/fetcher/imap.rb
I tried changing to : @connection = Net::IMAP.new(@server, @port, @ssl, nil, false)
Here is the stacktrace

Well it turns out the root cause on this one was ms exchange was misconfigured. I would love to have learned more about ssl errors and how to troublshoot them, but I just didnt get much info on this.
I did try to just troublshoot this using open ssl, fyi, you can do:OpenSSL> s_client -connect myserver:993
When it was broken, I received this error:CONNECTED(00000003)26831:error:140790E5:SSL routines:SSL23_WRITE:ssl handshakefailure:s23_lib.c:188:
Once we fixed I got a cert and handshake message etc.
Here is what my exchange admin said he did: "I just went to the IMAP protocol and went to the access tab. Then the certificates button. From there I chose to replace the cert and chose the new cert."
