Firewall

Hi everybody,
I installed DB Oracle, during installation i chose Enterprise Manager(EM) Tool. DB installed, but EM gave me error. I searched in metalink and found out that i got this because of ports for EM are closed and by firewall is installed by default on *nix OS.
I guess in my HP-UX 11i v3 firewall is running and ports for EM are closing.
So, how can i check is firewall running and how can i open\close required ports?

Re: Firewall

Did it list the port numbers it requires?
AFAIK on default HP-UX install no ports are blocked.

Re: Firewall

Srimalik, i'm not sure that ports are open.
Especially for EM i must have ports: 39, 55, ,5500 and 5519?

I got this error:

EM configuration failed due to the following error: Failed to allocate port(s) in the specified range(s) for the following proccesses JMS (5540-559), RMI (5520-5539), Database Control (5500-5519), EM Agent (3938) (1830-1849)
Refer to the log file at /u01/app/oracle/product/10.2.0./db_1/cfttoollogs/dbca/test/emConfig.log for more details.You can retry configuraing this Database with EM later by manually running /u01/app/oracle/product/10.2.0/db_1/bin/emca script

you can check these ports with telnet:

from localhost:
# telnet localhost PORTNUM

from a remote host:
# telnet MACHINE PORTNUM

Re: Firewall

Thanks, Viktor Balogh.

I did from local and remote host. But couldnt connect via telnet to those ports.
Then i run
LC_ALL=C netstat -an | greb LISTEN
but they are not runnung (nothing are listening\running on them).

Re: Firewall

Shalom,

From a Linux box you can do this to test HP-UX system. This util is something that with effort can be installed on an HP-UX host.

nmap hostname

This will list all open ports with listeners.

Re: Firewall

Hi rustam,

Did you install nmap on linux? I'm just curious, because I get every day a reminder about this topic, and find no new posts to it.
