Hi, RFC 5905 has in section 5.1.1.:
/* * Verify valid root distance. */ if (r->rootdelay / 2 + r->rootdisp >= MAXDISP || p->reftime > r->xmt) return; /* invalid header values */ But it seems that ntpd (at least 4.2.6p3 and 4.2.7p162) doesn't have the reftime > xmt check, only the distance check, is that correct?
