Since I have the honour to use a dialup connection regularly, I'd rather have a forwarding-only DNS server, since that will cut down the number of DNS packets on the dialup-link tremendously. The dhclient/named hacks are all very nice, but additionally I'll need the same in ppp.linkup. > >And there might be ISPs who disallow outgoing DNS connections to > >somewhere else than their own DNS servers. >=20 > Not us ;) Lucky you, but I'd rather go the local route, since this should always work and be faster (provided the "ISP"'s named is not overloaded) Ulrich Spoerlein --=20 PGP Key ID: 20FEE9DD Encrypted mail welcome!
