8.0 Client can't connect to 7.3 server?

I have following environment:

Server1, rh9, ip:192.168.1.10:
postgresql-7.3.4-3.rhl9
postgresql-libs-7.3.4-3.rhl9
postgresql-server-7.3.4-3.rhl9
postgresql-jdbc-7.3.4-3.rhl9

Server2, fc4, ip:192.168.1.11:
postgresql-libs-8.0.7-1.FC4.1
postgresql-8.0.7-1.FC4.1
postgresql-server-8.0.7-1.FC4.1
postgresql-jdbc-8.0.7-1.FC4.1
postgresql-contrib-8.0.7-1.FC4.1

I can't connect to server1 (7.3.4) using client (8.0.7) at server2.
I just get error:
psql: FATAL:  No pg_hba.conf entry for host 192.168.1.11, user joe,
database template1

Uncommented lines at server1's pg_hba.conf (postgresql service is
restarted after every change):
local all all trust trust
host all all 192.168.1.11 255.255.255.255 trust

Server1 also have line:
tcpip_socket = true
in postgresql.conf

Any ideas what's wrong?
