[Bug 999725] Re: broken start-up dependencies for ntp (starts before NIS is available)
No, nis is not on hosts line of nsswitch.conf. I agree that my case is not the same as the one reported. But since the problem here is reported to be one in which ntp is being started before the system is capable of resolving DNS, I couldn't help but notice the similarity to my previous problem in which dnsmasq was starting before the needed network interface was configured, and in the default configuration without the experimental dnsmasq configuration, it did not remedy that once the network interface finally was configured. So I wondered if something similar was in play with my new problem. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to ntp in Ubuntu. https://bugs.launchpad.net/bugs/999725 Title: broken start-up dependencies for ntp (starts before NIS is available) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ntp/+bug/999725/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

@John: Does the affected machine have "nis" on the "hosts" line in /etc/nsswitch.conf? If not then your problem is not the same as this one. ** Changed in: ntp (Ubuntu) Status: Expired => New -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to ntp in Ubuntu. https://bugs.launchpad.net/bugs/999725 Title: broken start-up dependencies for ntp (starts before NIS is available) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ntp/+bug/999725/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 999725] Re: broken start-up dependencies for ntp (starts before NIS is available)
I'm currently troubleshooting a problem with a Lubuntu Quantal setup with LTSP (terminal server network). Most of the clients stop responding at a blank/black screen during bootup. But only after successfully PXE network booting, getting DHCP assignments, and beginning the process of booting from an NBD image on the server. I see the Lubuntu splash screen and then the blank/black screen. I set up forwarding of the client syslog messages to the server, and the logs always end at a block of ntpd items, the last of which is "ntpd[1314]: Listening on routing socket on fd #24 for interface updates" I'm using network-manager for the network configuration. This is the default config, except that I am using the experimental statement in /etc/dnsmasq.d/network-manager which replaces the "bind-interfaces" line with a "bind-dynamic" line. That solved a client boot error "PXE-E32: TFTP open timeout" on the only client that currently boots successfully. This bug seems to have some behavior in common with Bug # 959037 at https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/959037 which also addresses DNS-related bootup problems. Comments?

[Bug 999725] Re: broken start-up dependencies for ntp (starts before NIS is available)
It is probably true that this has not been seen much as a bug due to DNS normally being available, hence NIS dependency (if present) being a secondary issue. However, we found that ntp did not recover by itself, so possibly it only tries to find the nameservers once, but will re-try for the time servers in ntp.conf I don't think it is necessary to test for any direct dependency on NIS in ntp.conf (that could be tricky) but a more robust approach would be to start (or restart?) ntp if a directory service is started/restarted just to make sure any such dependency or time-server changes are resolved. I presume this is the sort of thing Upstart can do. Incidentally it seems the last post for bug #604717 is spam, is there any way to get it deleted? -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to ntp in Ubuntu. https://bugs.launchpad.net/bugs/999725 Title: broken start-up dependencies for ntp (starts before NIS is available) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ntp/+bug/999725/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
