ODBC over Internet

Hi,

probably i am not the first asking this question:

When trying to connect to the backend tis rejects with:

User authentication failed
/usr/local/pgsql/bin/postmaster: ServerLoop: handling writing
8

the postmaster is started with the following Options:

-i -d 3 -B 256 -D ${PGDATA}

on client (ODBC) side the user- server- and portfield are filled in. the
port is controlled via loval telnet.

the $PGDATA/pg_hba.conf is:

local all trust
host all 127.0.0.1 255.255.255.255 trust
#host all 212.8.193.0 255.255.255.255 password
pg_pwd # (doesn't fitt too)
host all 212.8.193.0 255.255.255.255 ident

I found no helping hint in the docs. Would anybody write a short
mini-HOWTO who fixed this problem?

yours joerg
