Hi, Can anyone explain why this happens on a fedora host. # host www.xs4all.nl socket.c:1111: internal_send: 81.17.33.2#53: Invalid argument socket.c:1111: internal_send: 81.17.34.2#53: Invalid argument socket.c:1111: internal_send: 81.17.33.2#53: Invalid argument socket.c:1111: internal_send: 81.17.34.2#53: Invalid argument ;; connection timed out; no servers could be reached nslookup and dig give the same result. ---- cat /etc/resolv.conf nameserver 81.17.33.2 nameserver 81.17.34.2 ---- RH9 servers using the same nameservers have no problem.
