Hi to All,  
I have created a VM Suse Ent. 11SP2 in Vmware; on this machine I have installed Oracle DB 11g R2.  
But I am unable to connect from remote.  
For example when I try to connect to db, this message is returned:

[QUOTE]A test to establish a simple socket connection Failed on :1521.  
Your server is not listening or accept no connections on this host on port 1521[/QUOTE]  
The test is performerd using from command line ping :1521 and I have used both the qualified name and the IP.  
If I try to connect to another server with different OS (for example win2003, win2008 or rhel) I don’t have problem.  
Can someone help me ?  
Thank You and best regards  
Gaetano

Hi  
Have you opened the ports in the firewall to allow the service? If not,  
use YaST firewall to open.
