Php connection to remote mysql server

Question

Hi,
I've stragne problem using php 4.3.10 with Sun One 6.1 on Solaris 9. The connection to a remote mysql server fail. I've correct grants in both servers and the php.ini is setting to permit no limit connection to databases. the code:
$host='my-remote-server.com';
$link1=mysql_connect($host,"bla","blabla");
if$db1 = mysql_select_db("LOGIN",$link1);
$link = mysql_connect("localhost","bla","blabla");
$db = mysql_select_db("LOGIN",$link);
The remote connection fail but the local one works. When i work with another server Sun One 6 in Solaris 8 , everthing work wonderfull with the same deffinitions, it can connect the remote databases but the others machines can't connect the solaris 8 machine. i think there is something wrong in the solaris 9 or/and sun one 6.1 deffinition it avoid remote connection. The problem i don't know what may be wrong, which setting may affect tcp connections from web application in solaris 9/sun one 6.1 plataform.

Answer 1

we found the problem finally and may be useful for someone. Using the solaris 9 network snifer (snoop) we found that the default php timeout connection for mysql doesn't work ,this value is 60 in the php.ini . After 4 or 5 miliseconds php application closes the connection when it runs from the webserver , running from the shell it doesn't happen.The answer from the other server arrived after 20 or 30 milisecods then the connection to the databases fails. The solution is to put unlimited tiemout , mysql_connection_timeout=-1 then it success to connect the remote mysql server correctly. May be problem without timeout connection in case the other server doesn't answer, then application may wait forever or untill the system or webserver take out the application. I didn't check this posibilty, mainly i'm interesting the applications can work and write in the remote databases. If this definition cause problem as application waiting connection we always can try with another value greater than 60.
