Missing or erroneus pg_hba.conf file

From

Hello!

My server is working with pgsql 7.4.2 and Unix Solaris 8. Well, when a try a connection from my PC to the server, using pgAdminIII, I get the message above. This is my pg_hba.conf file:

local   all         all                                             trust
# IPv4-style local connections:
host    all         all         127.0.0.1         255.255.255.255   trust
host    all         all         172.17.0.0        255.255.0.0       trust

My PC IP address is something like 172.17.9.9 and local connections ("psql template1") are working fine. But if I comment the line below I can connect using pgAIII and locally too. After change pg_hba.conf I've used "pg_ctl reload".

#host    all         all         127.0.0.1         255.255.255.255   trust

My major problem is that in this last situation (with the line above commented) I can't use the pg73jdbc3.jar driver to connect to database (locally). The message is "no pg_hba.conf entry for host "127.0.0.1", user "postgres", database "ppcdr_db", SSL off". If I remove the comment, the "Missing or erroneus pg_hba.conf file" returns.

Can you help me?

Thank you!

SANDRO

There is an issue, as yet not understood (last I knew), with some
versions of (?) Solaris and IP-address-with-netmask configuration
entries in pg_hba.conf.  Try changing your two "host" lines to:

# IPv4-style local connections:
host    all         all         127.0.0.1/32      trust
host    all         all         172.17.0.0/16     trust

and see if that doesn't resolve your problem.

We've seen some reports suggesting that Solaris has a problem with the
all-ones netmask.  You could probably get it to work either by
loosening the netmask a little:

host    all         all         127.0.0.1         255.255.255.0   trust

or by using CIDR style:

host    all         all         127.0.0.1/32   trust
