Suggest:
ALL: ALL
This will deny access to all systems.
Then, you specifically add systems (or subnets) that you want to GRANT
access.
/etc/hosts.allow:
ALL: LOCAL, a.b.c.d, e.f., .foo.com, joker.goes.wild.org
The above will grant access to ALL services to:
LOCAL = your own machine (localhost = 127.0.0.1 when referenced from
your machine)
a.b.c.d = machine with ip number a.b.c.d
e.f. = all machines on subnet e.f, that is with ip numbers that
start with e.f (for example e.f.g.h, e.f.x.y,...)
NOTE the trailing "." It stands for "e.f.*.*"
.foo.com = all machines with domain name which ends with foo.com
Note the leading "." which means .foo.com = "*.*.foo.com"
joker.goes.wild.org = machine with that domain name
Note: you can specify access service by service explicitly instead of
using the keyword ALL (on the left side of :) if you need to.
Again, the strategy I follow is to first deny access to all, then add back
in explicit permission to enter.
