SSL Encryption

[Michael De Vlaminck]

Hello,

I'm trying to set up cups to use encryption.
I've inserted the following lines in cupsd.conf:

# encryption
ServerCertificate /etc/cups/ssl/cert.pem
ServerKey /etc/cups/ssl/key.pem
SSLPort 443
SSLListen 192.168.13.0:443
<Location />
<snip>
Encryption Required
</Location>

When I restart cupsd and try to go to the web interface I get a 'connection refused' error. When I check /var/log/cups/error_log I see the following line:
StartListening: Unable to bind socket for address c0a80d00:443 - Address already in use.

Can anyone help me getting this problem fixed?

thanks in advance,

Michael De Vlaminck
