[pkg-ntp-maintainers] Bug#399905: ntp: workaround for dynamic IP doesn't work any longer

[Joerg Sommrey]

Package: ntp
Version: 1:4.2.2.p4+dfsg-1
Severity: normal

Problems with ntpd and dynamic IP addresses have been discussed for
quite some time.  An agreed workaround was to use ntpdc's
unconfig/addserver commands.  However, after upgrading to the newest
Debian version, this doesn't work any longer.  From Wireshark and strace
I can see requests going out and responses coming back to ntpd via the
"whole world"-socket, but these seem to be discarded somehow.  No entries in
peerstats and ntpdc reports a reachability of zero.
