Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

Well, this problem is relatively hard to describe. I installed Webmin+Virtualmin in a server. I have multiple IP addresses in the server (two NICs bonded).

Let's assume that the network is

The Virtual Servers now are like this:

  • Listens to all addresses ( to
  • Self-signed certificate for SSL (issuer

  • Listens to
  • Self-signed certificate for SSL (issuer

You see, there's no problem at all using HTTPS at (other than complains because the certificate isn't signed by a CA). TLSv1 says Server Hello, exchanges key, and it's done.

The problem comes with or Firefox says ssl_error_rx_record_too_long.

I used Wireshark to examine the packets, and found that it ( or never sends the key or the 'Hello', but the index.php of the DocumentRoot of within the TLSv1 response. Wireshark classifies it as Alert (Level: Fatal, Description: Unexpected Message). The first 66 bytes conform with the expected header, and then Apache inserts the processed index.php -> "<html><head><title>Main page of!![...]" instead of the SSL key. That's in the packet were it is supposed to put the "Server Hello" (after a correct "Client Hello" from the client).

I don't know how to solve the issue, which is most likely related to the VirtualHost configuration. But the VirtualHost of has the same configuration than! -other than listening to only one IP instead of * (and of course, the SSL key, the SuexecGroup and the DocumentRoot fields are different).

Thanks in advance.
