Have used wwwoffle for some time now and find it incredibly useful.  This
morning I plucked up the courage to try the search facilities with htdig
etc.  Whichever one I try I get "Connection closed by remote server"
and nothing in the syslog.  Cannot figure it out at all.  Can anyone
help please? 2.8c with Opera on Slackware 9.1.
