This way you don't have run and config named. But this is different. A caching nameserver has its own merits. It avoids the ask-back at the forwarder for each address you need. This really makes a difference if the SLIP line is e.g. saturated by a fat ftp transfer, and the DNS packets would have to sit in the queue until their time has come. With a caching server, while almost no effort is needed to configure it, it will quickly remember the cached addresses, so the backoff will only happen on the first lookup of an address. Alternatively, lowering the MTU will make the line responding ``more quickly'', but at the cost of added overhead. Jörg
