Hello, I am still using "The perfect server Fedora 9 " to run my hotspot with Freeradius server. I want to get rid of the warnings about the validity of the certificate appearing in main and login window of chillispot. Reading the howto again, It seems the certificate is created for Postfix only. Code: mkdir /etc/postfix/ssl cd /etc/postfix/ssl/ openssl genrsa -des3 -rand /etc/hosts -out smtpd.key 1024 I have not installed IspConfig. How can I generate a valid certificate to open my " https://192.168.1.19/cgi-bin//hotspotlogin.cgi/ " page without this annoyances ? Great thanks for your help or any helpfull tip. Greetings to all. Camomille
