Default SSL Certificate Help!

Hey guys! Long time no see!

I need assistance regarding SSL Certificates.

I followed the ISPConfig 2 setup on Debian by Falko exactly, except for the hostname part.

The hostname was supposed to be www according to Falko's tutorial, that's the only thing I didn't do exactly as instructed.

Instead I made the hostname chronikal, instead of www...however I still use http://www.mysite.com:81 for the ISPConfig panel.

Previously, I had purchased a RapidSSL certificate which has expired. I had done everything as instructed and still got warnings in Internet Explorer saying "Certificate Mismatch" or something of the sort.

I am about to buy a new SSL Cert through Globalsign, ya know the expensive ass SSL certs, and I want to get it right.

I know the 3 lines to regenerate the OpenSSL cert, however my question is, can i have a machine with the fully qualified domain name of:


On the linux server, and still use vhosts to send people to:

https://www.mysite.com:81 - to access the the admin panel.

Do I have to change my hostname on my linux server to "www" or can I get the certificate to be valid, and not show the "mismatch error" as is.

Falko, Till, & all the others who have been so cool to share knowledge in the past, much respect to you!

Long live the ISPConfig krew!

Lemme know! Thanks fellas!

<< so did you previously successfully used the RapidSSL certificate on your server with the hostname "chronikal.mysite.org" ?

Default SSL help

Yes, well sort of. I generated the certificate using "www.mysite.com" instead of the server hostname chronikal.mysite.com which was used during the ispconfig 2 install.

Does the FIRST web used while installing ispconfig have to be used for SSL certs? I'm not educated when it comes to SSL stuff so thanks for your help.

I installed ISPConfig 2 when i was using Debian Etch 4.0 and Postfix was not in the repository then. It is now with Debian Lenny 5.0 and can be installed with apt-get/synaptic whatever.


The 365 day SSL cert has expired. When I tried the steps for regenerating a new certificate:

openssl genrsa -des3 -passout pass:password -out /root/ispconfig/httpd/conf/ssl.key/server.key2 1024

openssl req -new -passin pass:password -passout pass:password -key /root/ispconfig/httpd/conf/ssl.key/server.key2 -out /root/ispconfig/httpd/conf/ssl.csr/server.csr -days 3650

openssl req -x509 -passin pass:password -passout pass:password -key /root/ispconfig/httpd/conf/ssl.key/server.key2 -in /root/ispconfig/httpd/conf/ssl.csr/server.csr -out /root/ispconfig/httpd/conf/ssl.crt/server.crt -days 3650
I was unable to send mail period with webmail.

I had done this last year on my laptop & it had hardware failure so i didnt get to save all of my notes on what i did 365 days ago unfortunately.

Thanks for ur advice in advanced, let me know what i must do to just regenerate the OpenSSL certificate so i am still able to send mail with the ispconfig roundcube pkg!

I will figure out buying a new SSL cert with my ispconfig port 81 ssl cert later.
