[root@sydney ~]# nslookup adocom.dyndns.org Server: 220.127.116.11 Address: 18.104.22.168#53 Non-authoritative answer: Name: adocom.dyndns.org Address: 22.214.171.124 [root@sydney ~]# telnet adocom.dyndns.org 5432 Trying 126.96.36.199... Connected to adocom.dyndns.org. Escape character is '^]'.Connects fine from my box. How about firewalls? We had a weird case at work a while back where a router somewhere along the line was blocking all connections until it was ping'd - then after it received a ping, it'd keep the connection open for 20 minutes or so, then start blocking again. Turned out to be faulty!
One thing I would check is the domain name lookup. Make sure your DNS servers are properly configured and respond timely (within 2 seconds.) Repeatedly do a "dig adocom.dyndns.org A" from your client for a minute and see if any time out and/or fail.

Dirk...... Hi there, ive got a dynamic URL like myname.dyndns.org <http://myname.dyndns.org> which links to my server where my postgres database runs. The Problem is that the Connection fails with error: "Warning: pg_connect(): Unable to connect to PostgreSQL server: unknown host name: adocom.dyndns.org <http://adocom.dyndns.org>" Now, if i ping my dynamic address and use the resulting IP for the Connection all works fine. Are you running php on one machine and postgresql on a different machine?If so, maybe the dynamic address redirection service doesn't handle port 5432. Web servers typically use port 80.I don't know where my i did something wrong, i use an Java-Applet which connects also with the dynamic Address and works fine too. :(Does it connect with postgresql, or something else on the machine using a different port?I think you can use telnet (or ssh?) to manually connect to any port number of a host and see how (and if) the machine responds and get a better idea of what's going on.brew -- Strange Brew (brew@xxxxxxxxxxx <mailto:brew@xxxxxxxxxxx>) Check out my Stock Option website http://www.callpix.comand my Musicians Free Classified http://www.TheMode.com !DSPAM:37,454926c440414055797109!
