Can anybody else get ltrace to work with host? The usual reason for a delay is that you have more than one nameserver specified in resolv.conf and the first one tried is down or unreachable so you time out and retry. Try "dig @namserver hostname" with each of the nameserver addresses to see if they are working or just slow. -- Les Mikesell lesmikesell at gmail.com
