I followed all of the steps here very carefully, save one. I went through the ispconfig installation with "standard" rather than "expert" mode. I'm hoping that this is the solution to the problem I'm having. Everything in the How To went very smoothly. At the end. Since this is a test environment, the system has a hostname, but is setup as localhost.localdomain. After the completion of the install, I went to "https://my_ip_address:81", and got this message (firefox 1.5) "Could not establish an encrypted connection because certificate presented by 'my_ip_address' is invalid or corrupted. Error code: -8182 ... Any input to this would be greatly appreciated. I'm sure I followed every step here quite carefully (with the noted exception above). This is my first server install, so I was really quite pleased with the progress I had made until this.
