Hi,
I am using pgadmin to connect to postgresql server configured on a local machine. The Client and the Server are in the same Network.
When I try to access the postgresql server, I get the following error
--------------------------------------------------------------------
Unable to connect to postgresql server.No route to host, Is the server running on host 192.168.0.132 and accepting TCP/IP connections on port 5432?
---------------------------------------------------------------------
I checked the port on which postgresql is listening by the command.
nmap -sT -O localhost
----------------------------------
PORT STATE SERVICE
21/tcp open ftp
22/tcp open ssh
25/tcp open smtp
80/tcp open http
111/tcp open rpcbind
443/tcp open https
631/tcp open ipp
751/tcp open kerberos_master
3306/tcp open mysql
5432/tcp open postgres
----------------------------------
it tells me that postgresql is listening on port 5432.
I checked the status of the postgersql server. Its running.
Why is this problem caused?
Please advice.

Thanks

Can you ping 192.168.0.132 from the client?

the problem is resolved. I was using the wrong user.
Thanks

when i'm doing :-
nmap -sT -O 192.168.1.110
i can't see 5432 & 3306 port open. why & what to do?

Your mysql and postgres processes are not running. Try something like
/etc/init.d/mysql start
/etc/init.d/postmaster start

As of postgres, i think you need to do something like createdb first.
You may start a new thread.

this is all in fedora core 6. in last post you gave me 2 options to try but nothing happened.
now when i'm restarting mysql.
/sbin/service mysqld restart -u root
