Subject: deal gracefully with ipv6 address change
Date: Sun, 13 Dec 2009 09:15:02 +0100
Package: ntpd
Version: 1:4.2.4p4+dfsg-8lenny3
Severity: normal
Tags: ipv6

I recently deprecated an IPv6 prefix at home, but the clients running ntp
didn't deal well when the address disappeared:

  ntpd[21267]: bind() fd 18, family 10, port 123, scope 2, addr 2001:470:b40a:0:214:fdff:fe30:386a, in6_is_addr_multicast=0 flags=0x11 fails: Cannot assign requested address
  ntpd[21267]: unable to create socket on lan (12) for 2001:470:b40a:0:214:fdff:fe30:386a#123
  ntpd[21267]: failed to initialize interface for address 2001:470:b40a:0:214:fdff:fe30:386a

Thie keeps going on forever until I restart ntpd.

So you're running the version stable on squeeze/sid?

Do you have "dynamic" for your server/peer lines in ntp.conf?
(This is still required for the version in lenny, is the default
the version from squeeze/sid).
