I am running the pre-built Windows version of postgresql 8.1. I have
a local LAN with a 10.6/16 network. Apparently there's something more
than what's in the FAQ or my interpretation of the manual to get
remote connections working.

pg_hba.conf:
host all all 10.6/16 md5
host all all 127.0.0.1/32 md5

postgresql.conf:
listen_address = '*'

C:] psql -U postgres -d postgres -h swift
psql: FATAL: no pg_hba.conf entry for host "10.6.1.226", user
"postgres", database "postgres", SSL off

C:] psql -U postgres -d postgres
Password for user postgres:

If I remove the 127.0.0.1 line from pg_hba.conf, I cannot connect at
all.

What more do I need to do?

Paul,

Did you try:
host all all 10.6.0.0/16 md5

?

I believe you must list all 4 octets of the subnet. It says this in the docs:

The mask length indicates the number of high-order bits of the client IP
address that must match. Bits to the right of this must be zero in the given
IP address.

Which tells me the 0s have to be there.

Hm, that sure looks like it should work, or at least not fail in that
particular way. Are you sure you restarted or SIGHUP'd the postmaster
after setting up the pg_hba.conf file?

Oh, duh. The comments in inet_aton() show that it is interpreting
"10.6" in what most people nowadays would find a surprising way:

case 1: /* a -- 32 bits */
case 2: /* a.b -- 8.24 bits */
case 3: /* a.b.c -- 8.8.16 bits */
case 4: /* a.b.c.d -- 8.8.8.8 bits */

ie, it is read as if it were "10.0.0.6" ... hence no match, but also no
syntax error.

I've tweaked the SGML docs to make it clearer that omitting trailing
zeroes here isn't a good idea.

D'oh yes, I overlooked that. specifying 10.6.0.0 worked.

Thank you.
