Package: wide-dhcpv6-client Version: 20080615-13 Followup-For: Bug #725702 Having the symptoms of this bug as well.
This is from /var/log/syslog:

Strace shows this, associated with the last two lines, I think:

I suspect it's this fragment in dhcp6c.c (taken from upstream git repo):
290 if (setsockopt(sock, SOL_SOCKET, SO_REUSEPORT,
291 &on, sizeof(on)) < 0) {
292 dprintf(LOG_ERR, FNAME,
293 "setsockopt(SO_REUSEPORT): %s", strerror(errno));
294 exit(1);
295 }
... although it doesn't seem to correspond exactly with the strace output.
No idea why this would fail: socket(7) suggests this should be ok.
Vincent.
