Perhaps a firewall?  Setting the virtual_host parameter in
postgresql.conf?

Can you connect from the windows to the linux machine for any other
services it offers (not postgresql)?

5432 is default port for postgresql. I guess it has been occupied by
someone else. Try to run postgresql at some other ports. Remember to
modify your pg_hba.conf to put database server IP there. Your database then should be
//host:port/dbname.

It works for me.
