A quick google shows plenty of potentially related results <http://www.google.com/search?q=%2Bgrsec+NTP+IPv6> e.g. <http://bugs.gentoo.org/show_bug.cgi?format=multiple&id=326209> .... with grsec NTPd as root IPv6 worked, NTPd as user IPv6 didn't ... <BlockQuote> This problem occurs because ntpd does not have the needed privileges to access /proc/net/if_inet6 when not run as root (USE=caps). You can reconfigure to getthe same level of security by deselecting CONFIG_GRKERNSEC_PROC_USER and selecting CONFIG_GRKERNSEC_PROC_USERGROUP instead. You can then add the ntp user to the GID for the special group to get it to read the needed info from /proc. </BlockQuote> The above aside; Have you tried a current NTPd 4.2.7 ? In the last three years since the NTP 4.2.4p4 that you mentioned you were using, a lot of things have been worked on, IPv6 among them, e.g. <http://ntp.bkbits.net:8080/ntp-dev/?PAGE=search&EXPR=IPv6&SEARCH=ChangeSet+comments> ChangeSet 1.2082.4.156 IPv6 addresses in selecting default multicast source addresses. 1.2259 [Bug 1715] sntp utilitiesTest.IPv6Address failed. 1.2082.22.21 [Bug 1080] ntpd on ipv6 routers very chatty. 1.2082.4.97 [Bug 715] libisc Linux IPv6 interface iteration drops multicast flags. 1.2110.1.1 support for IPv6. 1.2082.4.41 Remove ipv6.c as unnecessary 1.2060.10.1 [Bug 1358] AIX 4.3 sntp/networking.c IPV6_JOIN_GROUP undeclared. 1.2060.3.1 [Bug 1343] lib/isc build breaks on systems without IPv6 headers. 1.2058 [Bug 1342] ignore|drop one IPv6 address on an interface blocks all 1.2037 fix ipv4/ipv6 which are not equivalent in the libopts sense 1.2026.1.1 [Bug 1324] support bracketed IPv6 numeric addresses for restrict. 1.2005 Ensure IPv6 localhost address ::1 is included in libisc's Windows IPv6 1.1935 [Bug 1272] gsoc_sntp IPv6 build problems under HP-UX 10. 1.1926 [Bug 1270] CID 70: gsoc_sntp recv_bcst_data mdevadr.ipv6mr_interface 1.1881.2.2 it safe to initialize ipv4_works and ipv6_works before init_io() 1.1881.2.1 3 weeks of changes including IPv6 on Windows which was 1.1873.1.1 some previously separate IPv4/IPv6 paths into a single codepath. 1.1875 [Bug 1200] Enable IPv6 in Windows port 1.1867 [Bug 320] restrict default should apply to both IPv4 and IPv6 1.1735.1.63 IPv6 interfaces were being looked for twice; fix bug 474 1.1735.4.4 [Bug 828] Fix IPv4/IPv6 address parsing 1.1739.1.6 hack ISC_PLATFORM_HAVEIPV6 1.1436.9.5 [Bug 977] Fix mismatching #ifdefs for builds without IPv6 1.1690 [Bug 977] Fix mismatching #ifdefs for builds without IPv6 1.1642 [Bug 828] correct IPv6 address parsing 1.1600 [Bug 771] compare scopeid if available for IPv6 addresses 1.1600 Bug 771: compare scopeid if available for IPv6 addresses 1.1379.1.49 when attempting to send to an IPv6 address of a local interface. -- E-Mail Sent to this address <blackl...@anitech-systems.com> will be added to the BlackLists. _______________________________________________ questions mailing list questions@lists.ntp.org http://lists.ntp.org/listinfo/questions
