Hi! It seems as if I celebrated to soon . I've been going through the installation again (all my VMWare VMs lost their network cards), and this time I'm running into the following problem: ISPConfig install completes, but when I'm trying to log into the admin interface, I get the following error message: Could not establish an encrypted connection because certificate presented by myserver.dyndns.org has an invalid signature. I've searched around for a solution, and one of the Google results was this thread right on these forums. I've run netsat -tap, and although ISPconfig was running in the output, I restarted it just to make sure. That's when I saw a warning message: Code: [email protected][email protected][email protected] My first question is what the error leading to that warning could be? Sadly, I cannot be certain whether it was there or not when ISPConfig first started up after installation. I plan on using the method of recreating the certificate in the way Falko recommends in that thread: Code: openssl genrsa -des3 -passout pass:yourpassword -out /root/ispconfig/httpd/conf/ssl.key/server.key2 1024 openssl req -new -passin pass:yourpassword -passout pass:yourpassword -key /root/ispconfig/httpd/conf/ssl.key/server.key2 -out /root/ispconfig/httpd/conf/ssl.csr/server.csr -days 365 openssl req -x509 -passin pass:yourpassword -passout pass:yourpassword -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 365 This is where my second question comes in. What is the "yourpassword" mentioned? Where does that come from? During the setup of ISPConfig I never had to enter a password for any certificates, so I'm stumped.
