One machine connects, the other doesn't???

Hi

I have postgresql 7.2.2-1 on "BACKEND".

If I use "Shop"(192.168.24.5) I can connect using the command:

psql mydatabase -h BACKEND -U ownerofmydatabase

I am asked for the password and upon giving it all is well.

BUT.

If I use "Office"(192.168.24.4) and I try the same thing:

psql mydatabase -h BACKEND -U ownerofmydatabase

I get:

psql: FATAL 1: No pg_hba.conf entry for host 192.168.24.4, user
ownerofmydatabase, database mydatabase

My pg_hba.conf file has two lines

local all trust
host all 192.168.24.0 255.255.255.0 password

Any ideas???
