I get a error msg when i try to connect to the DB

Hi

I have installed PostGRESql 7.4.17 and when i try to connect to the db i get the msg

psql: FATAL: no pg_hba.conf entry for host "???", user "sfmdb", database "LOGDB", SSL off

My pg_hba.conf entry is as below

# TYPE  DATABASE    USER        IP-ADDRESS        IP-MASK           METHOD

# Disable default configuration

local   all         all                                             trust
# IPv4-style local connections:
host    all         all         127.0.0.1         255.255.255.255   trust
# IPv6-style local connections:
host    all         all         ::1               ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff        trust

can you please guide me on what the problem might be.

Regards
