you need to have dns resolve to the same hostname forward and reverse ie 192.168.100.1 - > mycomputer.place.com mycomputer.place.com -> 192.168.100.1 you need to be incharge ( delegated to serve up 100.168.192.in-addr.arpa network ) to modify those dns names. john or you can take out the option in hosts.allow/deny for # check reverse dns == dns given #ALL : PARANOID : RFC931 20 : deny _______________________________________________ cobalt-security mailing list [EMAIL PROTECTED] http://list.cobalt.com/mailman/listinfo/cobalt-security
