Thread: pg_hba.conf issue
Hi friends, We have a product with Postgres 8.1 integrated for installations on Windows. The standard pg_hba.conf configuration going in the package is # TYPE DATABASE USER CIDR-ADDRESS METHOD # IPv4 local connections: host all all 127.0.0.1/32 trust # IPv6 local connections: #host all all ::1/128 trust #host all all 172.21.42.121/24 trust host all all 172.21.51.56/24 trust While this works at most of the locations, we have a peculiar error coming up at 2-3 locations. The error reads: no pg_hba.conf entry for host "::1" , user "crisil" , database "crisil" , SSL off " Can someone give any clue on why could this be coming up? We do not intend to use SSL either. Our analysis shows this problem gets resolved if the entry for ::1/128 is uncommented but we would like to understand in which scenario is this entry needed.

Hi friends,
I am Jayakumar and new to PostgreSQL world. I am using PostgreSQL 8.1.3
in Windows 2000 machine.
My problem is, I am unable to connect to PostgreSQL server from another
machine's psql client.
My system IP is 172.16.84.76, and client machine IP is 172.16.85.243.
I can connect to the PostgreSQL server with " psql -Uroot
-h172.16.84.76"
from same system(172.16.84.76)
If I give the above command from 172.16.85.243, results
D:\\Program Files\PostgreSQL\8.1\bin>psql -Uroot - h172.16.84.76
psql: could not connect to server: Connection refused (0x0000274D/10061)
Is the server running on host "172.16.84.76" and accepting
TCP/IP connections on port 5432?
I don't know how to do this in windows.
here pg_hba.conf entries follows
*************************************
host all all 172.16.84.76/32 md5
host all all 172.16.85.243/32 md5
here postgre.conf entry follows

Please find my problem, give me the solution...

No surprise: you have the IPv6 line commented out. Dunno why these
particular boxes are preferring IPv6 to IPv4, maybe something different
about the local DNS environment? Anyway, there is no point in refusing
to serve ::1/128 if you're accepting 127.0.0.1.
