I am trying to connect to postgresql remotely using pgAdmin2 (within my
private network) . my pg_hba.conf is as follows.
local      all         192.168.1.4                      ident   abcde
 host         all       192.168.1.4       255.255.255.255   ident   abcde

the serverlog is as follows
=======================================
parse_hba: invalid syntax in pg_hba.conf file at line 244, token
"192.168.1.4"
FATAL 1:  Missing or erroneous pg_hba.conf file, see postmaster log for

what's the proper way to setup pg_hba.conf to allow remote connection eith
from clients such as pgadmin2 or java (jdbc)? A sample file will be greatly
appreciated.

thanks
