for this to work hosts.deny denies all access to everyone with:
then in hosts.allow u can to add hostnames or ranges with a mask and a daemon name u allow access to like:
this will give ppl from everywhere access, or
"ftpd: ALL EXCEPT 188.8.131.52/255.0.0.0, 184.108.40.206/255.0.0.0" which gives ppl access from all IP ranges except those from a few pesky cablemodem pools.
*deleteing/emptying both files zeroes out deny of access.
the hosts file is just a static IP/fully qualified domainname list which u can use to faclilitate lookups before asking ure DNS server, so hasnt got anything to do with tcpwrappers (allow/deny).
