Package: ntp-server Version: 1:4.2.0a+stable-8 Severity: important ntpd segfaults when using specific servers, e.g. chime5.surfnet.nl. I suspect that it is caused by some ipv6 problem.
chime5.surfnet.nl has both an ipv4 and ipv6 address: [EMAIL PROTECTED]> host chime5.surfnet.nl chime5.surfnet.nl has address 194.171.167.130 chime5.surfnet.nl has IPv6 address 2001:610:1:400a:194:171:167:130 My machine doesn't have an ipv6 link, but it does have ipv6 support in the kernel (as a module actually, but it is automatically loaded by ifupdown or something). The problem disappears if I manually put the ipv4 address in /etc/hosts An strace of ntpd shows that it connect to my DNS and get the address of chime5.surfnet.nl, and tries to connect over ipv6. After that, ntpd reads /etc/services a few times and segfaults.
