hosts allow = wildcards

[plug bert]

Hello!

A good day to you all. i would like to know the exact
syntax for the hosts allow and hosts deny line. The
documentation states that the standard unix wildcards
will do ,  but i have nothad any success when i set
the ff options:


hosts allow = 192.168.37.*

or

hosts allow = 192.168.37.

or

hosts allow = 192.168.37.* 192.168.38.*

or

hosts allow = *.plugbert.com

or

hosts allow = *




Any suggestions? Thanks in advance.
