Need help in enabling remote connection

Hi,

I want a postgres client to be able to connect to a postgres sever on a remote machine.  But i'm not able to make it work.  Assume both the machines are on a LAN 10.0.0.* .Following available advice, this is what i did:

-- In pg_hba.conf, i added the line
host all all 10.0.0.1/24 trust

-- In postgresql.conf, i added the line
listen_addresses = 10.0.0.*

-- Restarted the server with the cmd
./pg_ctl -D <data_folder> reload

This doesn't work.  What else should i do to make remote connection work?

I'm lost!  Please help!

Thanks a lot,

Shruthi
