[Bug 1871194] Re: nagios-nrpe-server fails to launch after reboot
You are right. I thought tmpfiles.d had a hook so it would recreate the needed files/directories on a service (re)start, but apparently this is not the case. I think we can safely set the status of this report to Invalid. Thanks for both raising the issue and bringing it to a well understood conclusion. ** Changed in: nagios-nrpe (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1871194 Title: nagios-nrpe-server fails to launch after reboot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nagios-nrpe/+bug/1871194/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1871194] Re: nagios-nrpe-server fails to launch after reboot
We use libnss-ldapd. I think it may be sufficient to claim: "System users generally have to be resolvable during early boot already. This means they should not be provided by any networked service ..." [1] So, is this even a bug? If your OS uses systemd, then you need to ensure your system users are resolvable early in boot. I am disappointed that the tmpfiles service can't make your tmpfiles when you launch the service that requires them. I mean ... really? But that is life. Stick your nagios user and group in /etc/passwd and /etc/group and focus on those things that make you happy in this life. If you agree, then please feel free to close this out.

[Bug 1871194] Re: nagios-nrpe-server fails to launch after reboot
Thanks for clarifying. Systemd should support resolving users via LDAP, with a caveat: the service providing the users should be running when the user resolution is requested [1]. This may be a problem at boot time, but not once the boot has completed. This is why I was insisting on trying to start the service after the boot process was complete. As it *should* be quick and easy I'd give a shot at replacing libnss- ldap with libnss-ldapd. From [2]: libnss-ldap has some known issues with serving host information and lookups during boot which should be addressed in libnss-ldapd.

[Bug 1871194] Re: nagios-nrpe-server fails to launch after reboot
Paride, IF the nagios user is in LDAP, then /var/run/nagios will not be created by systemd at boot time, or any time after that. I can confirm that the following sequences fail to get nagios-nrpe- server running: sudo service nagios-nrpe-server restart sudo service nagios-nrpe-server stop sudo service nagios-nrpe-server start sudo systemctl stop nagios-nrpe-server sudo systemctl start nagios-nrpe-server Nothing in there triggers systems to create the missing directory: May 05 11:04:08 dmz-gnt03-04 systemd[1]: Started Nagios Remote Plugin Executor.

I mean starting it manually using systemd, like this: systemctl stop nagios-nrpe-server # just in case systemctl start nagios-nrpe-server # does this succeed? Starting the service like this shouldn't be any different than starting it at boot. ** Changed in: nagios-nrpe (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1871194 Title: nagios-nrpe-server fails to launch after reboot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nagios-nrpe/+bug/1871194/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1871194] Re: nagios-nrpe-server fails to launch after reboot
Paride, unfortunately, when systemd fails to create /var/lib/nagios during system boot, the nagios-nrpe-server service can not be started manually. If the operator creates the missing directory and chowns it to nagios, they can then start the service manually. ** Changed in: nagios-nrpe (Ubuntu) Status: Incomplete => New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1871194 Title: nagios-nrpe-server fails to launch after reboot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nagios-nrpe/+bug/1871194/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1871194] Re: nagios-nrpe-server fails to launch after reboot
Hi Danny, thanks for the digging. Can the service be started manually, when all the other services (including LDAP) are already running? I'm setting the status of this report to Incomplete for the moment, which is our way to keep track of bugs where we're waiting for further feedback. Please change the bug status back to New after commenting back.

[Bug 1871194] Re: nagios-nrpe-server fails to launch after reboot
I am still testing but it looks like the problem for me is that we have (had) the nagios user in LDAP. Systemd says that the tmpfiles.d stuff will NOT work when you specify a non-local user. I think it is more correct to provision our system-level users in system-level files. I should have a more conclusive understanding next week, but this bug may be more of a feature request, at best. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1871194 Title: nagios-nrpe-server fails to launch after reboot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nagios-nrpe/+bug/1871194/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1871194] Re: nagios-nrpe-server fails to launch after reboot
Checking the systemd-tempfiles documentation (https://freedesktop.org/software/systemd/man/tmpfiles.d.html#Description) makes me think we could use RuntimeDirectory to fix this issue: System daemons frequently require private runtime directories below /run to store communication sockets and similar. For these, is is better to use RuntimeDirectory= in their unit files (see systemd.exec(5) for details), if the flexibility provided by tmpfiles.d is not required. The advantages are that the configuration required by the unit is centralized in one place, and that the lifetime of the directory is tied to the lifetime of the service itself. ** Changed in: nagios-nrpe (Ubuntu) Status: New => Triaged ** Changed in: nagios-nrpe (Ubuntu) Importance: Undecided => Medium -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1871194 Title: nagios-nrpe-server fails to launch after reboot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nagios-nrpe/+bug/1871194/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
