PGAdmin connection to PostgreSQL

P: 1
PG Admin Version 1.6.0 (Nov 15 2006, rev 5641) Running on Windows 2000
PostgreSQL 8.2.6, running remotely on Linux

pg_hba.conf contains the record ...
host all all 12.345.678.90 trust
where 12.345.678.90 is the IP address that I am trying to connect from

Database started with
/usr/local/pgsql/bin/pg_ctl -D /usr/local/pgsql/data -o -i start

None of these settings have changed.

Work undertaken in last 24 hours to create a cron job on the linux machine that completes a pg_dump backup of PostgreSQL and zips it up. A Windows scheduled job then hooks into the Linux machine and performs a get on that file. This seems to be working OK and is as far as I can tell the only thing that has changed. This process did involve a hardware reboot.

Tomcat 5.5 also running on same box, also connecting to database. This connection is still working OK.
Same instance of PGAdmin connects to two other Db instances, one local and one remote on a different server. Both work fine, but PGAdmin can no longer connect to the main remote database.

Message appears in lower left corner "Connecting to database... Failed"
I have turned logging onto Debug and get the following records in the log file for each connection attempt ...

I can still connect to the Linux Box, I can logon to psql and have attempted to change the password for my postgres user in case that was my problem. It made no difference.

I do appreciate that the symptoms that I am describing suggests that PGAdmin is fine and it is likely to be the Server and or the PostgreSQL instance that is at fault. I am not new to either PostgreSQL or PGAdmin having been a frequent user of both for 3-4 years, however I am at a loss as to what is causing this so any clues would be much appreciated.

If I have missed something off that might help you diagnose, please let me know.

In anticipation, many thanks !!!

I know it has been awhile since this was posted but it might help others having the same problem...

You need to check that the postgresql.conf file parameter, listen_addresses, is set to accept remote connections. It defaults to localhost so change it to '*' so it can listen to for any IP connection or specify a specific IP address.
