Jay, want to add this config change to the shipped xinetd.conf ? Mind if I add this to the FC3BugWeekTracker ? Unfortunately it is not that easy, we need to either fix xinetd to respect the flags=IPv6 in /etc/xinetd.conf or to add this line to every service in /etc/xinetd.d I'm the upstream maintainer of xinetd. The xinetd.conf man pages state what attributes can be default. flags is not one of them. The flags attribute was intended to be a per service tweek. Some of the options in flags can make bad things happen if they were inherited. For example, nameinargs or sensor. To solve your problem, put a flags = IPv6 in each service that you want to listen on IPv6. Unix has a tradition of giving its users plenty of rope to hang themselves. Having flags that make bad things happen may be a bad design but it does not justify disabling a functionality that has its valid use. Most programs support IPv6 by default if available at compile time, I think that xinetd should follow this example. Setting "flags = IPv6" in the defaults section or specifying a command line flag would be an acceptable solution. Having to ass "flags = IPv6" in every single configuration file is just a pain that effects dozens of package maintainers from Fedora and elsewhere. PTC. Your best bet for getting such a patch accepted upstream will be to split flags into two configuration options, one of which contains only flags that make at least some sense to set as defaults (and can be listed there), and another that contains per-service-only flags. Don't forget to update the documentation too. >Setting "flags = IPv6" in the defaults section or specifying a command line >flag would be an acceptable solution. I'll think about it. Xinetd is not under heavy development these days. We are only making small changes. Its basically "done". >Having to pass "flags = IPv6" in every single configuration file is just a pain >that effects dozens of package maintainers from Fedora and elsewhere. This doesn't affect any package maintainers. They have no idea what anyone's machine is running nor should they. This is a site customization for the local admin. I'll mull over this request and see how big the changes are. I guess you are right, xinetd is pretty much done for IPv4, but the Internet is transitioning to IPv6 and when a site administrator enables a service it should be enabled for both IPv4 and IPv6 unless explicitly told otherwise. Unfortunately xinetd's current IPv6 support looks more like a hack. For Fedora or any other Linux distribution to support IPv6 each package that depends on xinetd must be changed to include "flags=IPv6". |
