Bug#585966: pdns-server: init.d script should provide the virtual facility $named
[Petter Reinholdtsen] This fix is wrong. The file is stored in /etc/insserv.conf.d/pdns-server/pdns-server.insserv, while it need to be stored in /etc/insserv.conf.d/pdns-server. The extra directory level make insserv ignore the file. Reopening the bug because of this. It just occured to me, that for pdns to work as $named (ie doing any DNS lookup), the recursor should be running too. To ensure this, the insserv.conf.d/ file should have this content: $named pdns +pdns-recursor The + make the recursor a optional dependency, to make sure init.d scripts do not fail to install if it is not installed.

Bug#585966: pdns-server: init.d script should provide the virtual facility $named
[Matthijs Möhlmann] What contents should the file /etc/insserv.conf.d/pdns-server have? I believe this is the content needed: $named pdns It will add a hard dependency from $named to pdns. For the other bug reported, I'll check if the pdns-server is running or not before letting the script proceed. Great. Not sure if that is enough. Perhaps it is a idea to verify that it is listening on its port and replying to requests before continuing? The proper fix would be to change the source to make sure the config is loaded and the ports bound before forking, to ensure the server is operational. I'm planning to upload the package this afternoon. Great. :) Happy hacking, -- Petter Reinholdtsen -- To UNSUBSCRIBE, email to debian-bugs-rc-requ...@lists.debian.org with a subject of unsubscribe.

Bug#585966: pdns-server: init.d script should provide the virtual facility $named
Hi. Do you have any feedback on this issue? Should I NMU to add the $named virtual facility to at least improve the situation? Adding 'sleep 5' after starting the service might provide a workaround for the fact that pdns is not ready to answer requests imediately after the init.d script ends, by buying more time for pdns to get ready.

Bug#585966: pdns-server: init.d script should provide the virtual facility $named
Hm, making pdns implement the $named virtual facility do not seem to be enough. The server is not accepting DNS requests when the init.d script exits, causing dhcpd to fail to start even if its init.d script depend on $named. This syslog snipped show the issue. Notice how the LDAP server is operational first, pdns starts, dhcpd starts and then pdns report that it is listening to DNS requests on TCP and UDP: Jun 16 13:32:23 tjener slapd[2341]: slapd starting Jun 16 13:32:24 tjener pdns[2358]: Listening on controlsocket in '/var/run/pdns.controlsocket' Jun 16 13:32:24 tjener pdns[2363]: Guardian is launching an instance Jun 16 13:32:24 tjener pdns[2363]: Reading random entropy from '/dev/urandom' Jun 16 13:32:24 tjener dhcpd: Connecting to LDAP server ldap:389 Jun 16 13:32:24 tjener dhcpd: Successfully logged into LDAP server ldap Jun 16 13:32:24 tjener dhcpd: Cannot find host LDAP entry dhcp ((objectClass=dhcpServer)(cn=dhcp)) Jun 16 13:32:24 tjener dhcpd: Configuration file errors encountered -- exiting Jun 16 13:32:24 tjener dhcpd: Internet Systems Consortium DHCP Server V3.1.3 Jun 16 13:32:24 tjener dhcpd: Copyright 2004-2009 Internet Systems Consortium.

Bug#585966: pdns-server: init.d script should provide the virtual facility $named
Package: pdns-server Version: 2.9.22-5 Severity: grave Tags: patch User: debian-...@lists.debian.org UserTags: debian-edu User: initscripts-ng-de...@lists.alioth.debian.org Usertags: incorrect-dependency The init.d script in the pdns-server package do not provide the virtual facility $named, causing all init.d scripts expecting the DNS server to be operational when they start during boot to fail. I discovered this with the Debian Edu main-server profile, were we include a lot of services on the same machine. Setting the severity to grave, as this causes other packages to fail to start properly at boot when used on a machine with pdns as the local DNS resolver. Providing a virtual facility is implemented by adding a file in /etc/insserv.conf.d/. Here is a patch to implement this for pdns-server. diff -uNr pdns-2.9.22/debian/pdns-server.insserv pdns-2.9.22-pere/debian/pdns-server.insserv --- pdns-2.9.22/debian/pdns-server.insserv 1970-01-01 01:00:00.0 +0100 +++ pdns-2.9.22-pere/debian/pdns-server.insserv 2010-06-15 10:55:49.858068000 +0200 @@ -0,0 +1 @@ +$named pdns diff -uNr pdns-2.9.22/debian/rules pdns-2.9.22-pere/debian/rules --- pdns-2.9.22/debian/rules2010-04-07 22:34:37.0 +0200 +++ pdns-2.9.22-pere/debian/rules 2010-06-15 10:57:14.054724000 +0200 @@ -87,6 +87,10 @@ # Install the stuff $(MAKE) install DESTDIR=$(CURDIR)/debian/tmp $(MAKE) -C pdns/docs html/index.html + # Set up init.d virtual facility + mkdir -p $(CURDIR)/debian/pdns-server/etc/insserv.conf.d + cp $(CURDIR)/debian/pdns-server.insserv \ + $(CURDIR)/debian/pdns-server/etc/insserv.conf.d/pdns-server dh_install Happy hacking, -- Petter Reinholdtsen -- To UNSUBSCRIBE, email to debian-bugs-rc-requ...@lists.debian.org with a subject of unsubscribe.
