Bug#736515: openntpd: Does not survive IP address update by dhclient
Package: openntpd
Version: 20080406p-10
Followup-For: Bug #736515
Control: tags -1 +patch
I was wrong: simply dropping stuff in the dhclient hooks does *not*
work when network-manager is used.
In my case, the ifup.d directory fixed the problem: it turns out there
is already a script there, but it works only if there is a "listen"
line in the config file, which is incorrect, as this bug report shows.
The following is a modified config file that works here.

Bug#736515: openntpd: Does not survive IP address update by dhclient
Package: openntpd Version: 20080406p-4 Severity: normal Openntpd stops working and starts spamming syslog when the IP address of the interface having the NTP server connections changes, like after a DHCP update. The syslog shows something like this: -*- Jan 24 09:07:57 xxx dhclient: bound to zz.zz.zz.zz -- renewal in 818 seconds. Jan 24 09:09:29 xxx ntpd[2474]: sendto: Invalid argument Jan 24 09:10:29 xxx ntpd[2474]: sendto: Invalid argument ... -*- The 'Invalid argument' messages continue a few times per minute, until openntpd is restarted. Looking at the openntpd package files, there is a /etc/network/if-up.d/openntpd file which is supposed to restart openntpd when an external interface comes up. I'm not sure whether a network interface should go down and up during IP address change, but if that is the case, then the bug is in isc-dhcp-client. If network intefaces should stay up during IP address change, then this bug could be fixed for dhclient using systems by placing a restart script similar to ifupdowns to /etc/dhcp/dhclient-exit-hooks.d -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.
