After a powerfailure of 10hours I have got my database server back up and
the phpBB2 that a site uses is not working. Here is the error.

Warning: pg_connect() unable to connect to PostgreSQL server: could not
connect to server: Connection refused Is the server running on host
database.lhasi.org and accepting TCP/IP connections on port 5432? in
/var/www/html/dealingwithcrohns/phpBB2/db/postgres7.php on line 79
phpBB : Critical Error

Could not connect to the database

The machine is a RH9 box with the latest postgres running from redhat update.

I have webmin on the machine which shows the databases there but i keep
getting this error

The machine didn't come up with any errors or bad blocks with the auto fsck
so i am confused.

Can anyone help?

Firewalling maybe? Check which ports are open with nmap.

Re: Errors after power failure

Heres what is get with nmap localhost

pgsql-general@postgresql.org

[root@database root]# nmap localhost

Starting nmap V. 3.00 ( www.insecure.org/nmap/ )
Interesting ports on database (127.0.0.1):
(The 1590 ports scanned but not shown below are in state: closed)

22/tcp open ssh

6000/tcp open X11
10000/tcp open snet-sensor-mgmt

Nmap run completed -- 1 IP address (1 host up) scanned in 2 seconds
[root@database root]#

And I doublechecked to make sure postmaster was running

Here is what is in the log file

Re: Errors after power failure

I would suspect the manner in which it was started. Does your postresql.conf
file have tcpip_socket=true?. If it is set to false and the script that
starts Postgres does not use the '-o -i' switch then the database will not
accept tcpip connections. Have you tried psql on the database host to see if
it can accept local connections via a unix socket?

Re: Errors after power failure

If I could kiss you I would.

Everything is working now.

Apparently an old script I had was switched and you were right...the old
script was
not starting tcp connections....so...I enabled it in the postgresql.conf and
it is ok

Thank You

-Dan

Thanks for everyones help!!
