TCP/IP connection

Hi,
Upgraded to 8.3.0 it is up and running. (see below for config)
But apparelntly I don't have my pg_hba.conf file set correctly for
web applications using my database.
This is what I have: (I only want OHSU machines to be able to log on
(137.53.n.n)

# TYPE DATABASE USER CIDR-ADDRESS METHOD

# "local" is for Unix domain socket connections only
local all all trust
# IPv4 local connections:
host all all 127.0.0.1/32 trust
host all all 137.53.0.0/16 md5

# IPv6 local connections:
host all all ::1/128 md5

This gives me a "Can't connect ..." error.

What have I messed up?

thanks so much,

Tom
