I was experiencing slow boot times on a ppp-connected machine (sendmail would pause, waiting for my *misconfigured* diald to *not* dial in). A fix which works well for me was to reconfigure that machine's named to be a secondary server for each of the reverse domains it lived on (you need to specify a backup file location for each domain, which should be standard practice for most folks anyway, for this to work on a dialup). By doing so, most relatively local reverse lookups are incredibly quick. Pete -- Peter J.
