Hello All, I run Tru64 Unix 5.1B / Alpha OSF1. I have installed Postgresql 8.0.3 on a cluster. The following is my pg_hba.conf, " host dcs all 127.0.0.1 255.255.255.255 password host dcsconfig all 127.0.0.1 255.255.255.255 password local all all trust # IPv4-style local connections: host all all 127.0.0.1 255.255.255.255 trust # IPv6-style local connections: host all all ::1/128 trust host all all 15.70.194.25 255.255.255.255 trust " Immaterial of whether I configure IPV6 or not, I keep getting the following Error whenever I try to connect to postmaster. I get the following error:: psql: FATAL: missing or erroneous pg_hba.conf file HINT: See server log for details. In the postmaster.log, LOG: invalid IP address "::1" in file "/usr/internet/pgsql/data/pg_hba.conf" line 77: Unknown server error FATAL: missing or erroneous pg_hba.conf file HINT: See server log for details. In the source I have set HAVE_IPV6 as 1. Am I missing anything ?? Thanks in Advance. -- Rajesh R
