Hi,
I have installed 11.2.0.3 onto an Oracle Linux 6.3 platform. I have just installed OEM DB Control and from the server console I can run Firefox on the server and logon to OEM.
However from my laptop ( on the same network ) I can ping lab1.nms from my laptop and I can do telnet lab1.nms 22 ( i.e. the SSH port - as Linux 6.3 does not use telnet but rather ssh )
So I know the local names resolution ( from my hosts file ) on my laptop is correct
However when I do both of the following :
telnet lab1.nms 1521
telnet lab1.nms 1158
Both times the host is unreachable ( yet when I check on the server, the Oracle Listener and OEM are running on the ports above )
It doesn't matter if I use the explicit ip address instead, the host is still unreachable on these port.
There is no firewall between my pc and server, I literally have a switch and the server and my laptop plugged into it ( so effectively all ports with a service on it, should be open ). Is this something with Windows pc to Linux server communication ? Is it something to do with port reservations on Linux ?
any help appreciated,
Jim
