I have two linux PCs, both running fedora 11 with NTP ver. 4.2.4p7.
PC1 has 192.168.1.1 and 2002::c0a9:0101 addresses
PC2 has 192.168.1.2 and 2002::c0a9:0102 addresses
ntpd is running on PC1.
on PC2 ntpdate 192.168.1.1 returned good timing from PC1
But ntpdate 2002::c0a9:0101 did not work
Wireshark runs on PC1 shows NTP client messages from 2002::c0a9:0102 are received properly, but instead of replying with NTP server messages, PC1 is sending ICMPV6 unreachable (administratively prohibited) messages.
Yet from PC1 ping6 2002:c0a9:0102 works fine.
On PC1 ntpdate -u 2002::c0a9:0101 also works via loopback interface.
Could anybody gives me some hint on why NTPD ignores the IPv6 NTP client messages?
Thanks,
Joan
