Hello again, I have DTags 1.1.0.1.fc10: # rpm -qi pki-ca Name : pki-ca Relocations: (not relocatable) Version : 1.1.0 Vendor: Red Hat, Inc. Release : 1.fc10 Build Date: Sat 04 Apr 2009 10:00:35 AM PDT Install Date: Mon 13 Apr 2009 10:55:06 AM PDT Build Host: localhost.localdomain Group : System Environment/Daemons Source RPM: pki-ca-1.1.0-1.fc10.src.rpm Size : 830321 License: GPLv2 with exceptions Signature : (none) Packager : Red Hat, Inc. <http://bugzilla.redhat.com/bugzilla> URL : http://pki.fedoraproject.org/wiki/PKI_Documentation Summary : Dogtag Certificate System - Certificate Authority Is there a 'relatively easy' way to configure the pki-ca webserver to respond to an IPv6 address? (I'll take the hard way too!) # netstat -tlpn is only listing the default installation listening to IPv4 (but not the IPv6 address): tcp 0 0 0.0.0.0:9443 0.0.0.0:* LISTEN 16960/java https://[2001::5]:9443/ca/services BTW, I have DNS to resolve for both IPv4 and IPv6.
