Обсуждение: trying to connect to pg from within a local network
// __ trying to connect from 10.0.31.62
~
Hi,
~
I need to connect to a pg Windows installation that I have within the
same network
~
as listen_address I have listed: localhost, 127.0.0.1, 10.0.31.5, 10.0.31.62
~
10.0.31.5 is this "localhost" in the 10.0.31.* local network and
10.0.31.62 is me
~
I have check all I can think of and it still does not work. Why can't
I connect to pg from within the local network?
~
Thanks
lbrtchx

Allowing certain client IP addresses is done in pg_hba.conf. If that is NOT the problem: Try the following on the client: telnet 10.0.31.5 5432 and tell us the response. Try the following on the server: netstat -a and tell us what you get. Is there a firewall involved? Yours, Laurenz Albe

OK, I did too, this is how my /data/pg_hba.conf looks like:

CIDR-ADDRESS is a single address range. Try putting 10.0.31.62/32 on a separate line. jan -- -------------------------------------------------------------- Jan de Visser jdevisser@digitalfairway.com Baruk Khazad!

Now, I am also getting "connection refused" messages even though I do
know tc is running since I can check it with pdAdmin3

At least on port 139. Could still be that a firewall blocks other ports. Ok, let's sum up: - Your server is up and running (you can connect locally). - Your server is listening on port 5432. - You cannot open a TCP connection from client to server on port 5432 (but on port 139 you can). That looks too me like a network/firewall problem. I know too little about networks, particularly on Windows, to tell you how to proceed. But to confirm my suspicion, there's a few things you can try: - From the client, try "telnet 10.0.31.5 139". That should not give you an error message. - From the server, try "telnet 10.0.31.5 5432". That should also not give you an error message. If these two work, but "telnet 10.0.31.5 5432" from the client gives you a "connection refused", I don't know whom to blame but the network configuration. Yours, Laurenz Albe
If the server is running on Windows, all recent versions of Windows run a built-in firewall by default that will block remote access to the PG port. Have you confirmed that the firewall is either not running, or has an exception for the PG port? -- Mark Lewis On Thu, 2008-01-17 at 16:46 +0100, Albe Laurenz wrote: > Albretch Mueller wrote: > > > Now, I am also getting "connection refused" messages even though I do > > know tc is running since I can check it with pdAdmin3 > > > > org.postgresql.util.PSQLException: Connection refused.

Well, I went:
~
Start > Control Panel > Windows Firewall
~
and it is: "off (not recommended)"
~
Something I still am not sure about is how to:
~
"Check that the hostname and port are correct and that the postmaster
is accepting TCP/IP connnections"
~
There is nothing I can see in pg_hba.conf or postgres.conf that
relates to TCP/IP connnections and I think it is a pg thing, because
when I run tomcat on port 8080 on this box, I can telnet to it without
any problems
~
Tomcat is using a pg-based JDBCRealm, that means it is connecting to
it without any problems

On my Solaris box, which btw is really picky about security, here is how my config looks like, note that I have two ethernet interfaces on it, dn-2xe32-iprb0 and dn-2xe32-e1000g0.
Also my local network is on 192.168.1.0.
postgresql.conf
----------------------
# - Connection Settings -
listen_addresses = 'localhost, dn-2xe32-e1000g0'
# what IP address(es) to listen on;
# comma-separated list of addresses;
# defaults to 'localhost', '*' = all
# (change requires restart)
port = 5432 # (change requires restart)
# what IP address(es) to listen on;
# comma-separated list of addresses;
# defaults to 'localhost', '*' = all
# (change requires restart)
port = 5432 # (change requires restart)
-----------------
pg_hba.conf
-----------------
-----------------
# IPv4 local connections:
host all all 127.0.0.1/32 trust
host all postgres 192.168.1.0/24 md5
host all pguser2 192.168.1.0/24 md5
-----------------
host all all 127.0.0.1/32 trust
host all postgres 192.168.1.0/24 md5
host all pguser2 192.168.1.0/24 md5
-----------------
Also I have seen in your first email an entry listen_address instead of listen_addresses, can you double check if there is no spelling error somewhere, you never know.
Did you try listen_addresses='*' and see if that would listen more than localhost?

There is nothing I can see in pg_hba.conf or postgres.conf that
relates to TCP/IP connnections and I think it is a pg thing, because
when I run tomcat on port 8080 on this box, I can telnet to it without
any problems

Never miss a thing. Make Yahoo your homepage.

Have you talked to the people who manage your network? Yours, Laurenz Albe
