ORMI port ranges problem

From the following Guide:
http://download-west.oracle.com/docs/cd/B14099_19/core.1012/b13995/ports.htm#ASADM301
"When changing an OC4J port number, you typically specify a new port range. The range may be a simple port range (12501-12600), a comma separated list of ports (12501, 12504, 12507), or a combination of both (12501-12580, 12583, 12590-12600). By default, the ranges contain 100 ports. If you specify a range that is too narrow, you may encounter problems when starting OC4J instances. The AJP and RMI port ranges are required; the others are optional."
The problem I'm having is that an external client application needs to know the ORMI port of an OC4J instance running on OAS; but the port can by dynamic. I was thinking of just removing the port range (ex: set it to 3203-3203), but the above warning concerns me...
Any thoughts?

Good question.
What we do in this case is to use a JNDI URL that uses the fixed OPMN service to locate the port for the target OC4J instance. This insulates you from any movement in the ORMI port on the OC4J instance when its started.
See the EJB doc here --
http://download-west.oracle.com/docs/cd/B14099_19/web.1012/b15505/access.htm#i1019709
Location
All ports, including the RMI port, are dynamically set by OPMN when each OC4J instance starts. When you specify the following URL in the client JNDI properties, the client-side OC4J retrieves the dynamic ports for the instance, and chooses one from the list for communication.
java.naming.provider.url= opmn:ormi://<opmn_host>:<opmn_port>:<oc4j_instance>/<application-name>
The OPMN host name and port number is retrieved from the opmn.xml file. In most cases, OPMN is located on the same machine as the OC4J instance. However, you must specify the host name in case it is located on another machine. The OPMN port number is optional; if excluded, the default is port 6003. The OPMN port is specified in opmn.xml.
The reason we have a port range is
1. To support multiple installations on the same server, so that ports don't conflict.
2. To support the situation where you run multiple processes for the OC4J instance definition (so they all need different ports running on the same machine)
If you don't run into any of these, then setting a single port in opmn.xml for ORMI is fine and you can then configure the client to use the fixed, known port.

Problem with Port Range Forwarding WRV54G

I have configured my WRV54G to do the following, in this order, on the Port Range Forwarding page of the router:
1. Forward port 3389 to LAN Static IP x.x.x.100, a desktop PC. I have confirmed this works, a port scan shows this port is open and I can remote desktop into x.x.x.100
2. Forward port 443 to LAN Static IP x.x.x.101. I have confirmed this works, a port scan shows this port is open I can VPN to an SSL concentrator at x.x.x.101
3. Forward port 3390 to LAN Static IP x.x.x.102, a desktop PC. THIS DOES NOT WORK. A port scan shows that this port is not open. I have configured the remote desktop host at x.x.x.102 to use port 3390. Netstat shows that x.x.x.3390 is listening on this port. I can remote desktop to x.x.x.102 from inside the LAN, no problem, so it's not an issue with the PX configuration.
So, then I switched the order of the port forwarding instructions, in this order, as follows:
1. Forward port 3389 to LAN Static IP x.x.x.100, a desktop PC. I have confirmed this works, a port scan shows this port is open and I can remote desktop into x.x.x.100
2. Forward port 3390 to LAN Static IP x.x.x.102, a desktop PC. I have confirmed this
works, a port scan shows this port is open and I can remote desktop into x.x.x.102
3. Forward port 443 to LAN Static IP x.x.x.101. THIS DOES NOT WORK. Port scan shows this port is not open.
It looks like the WRV54G is only recognizing the first two entries in the Port Range Forwarding table and IGNORING the third entry. HELP??!!
I have the latest firmware installed: v2.39.2e
Anyone have a solution? Thanks in advance!

Are you still using the DHCP server range of x.x.x.100 through x.x.x.149 ? If so, then your problem may be that you are using illegal fixed LAN IP addresses.
With Linksys routers, any fixed LAN IP address must be outside the DHCP server range, and it cannot end in 0, 1, or 255.
I would suggest that you fix the illegal addresses, then see if that resolves your problem.
Here is the full set of rules for using fixed LAN IP addresses:
With Linksys routers, a fixed (static) LAN IP addresses must be assigned in the device that is using the address. So you need to enter the fixed address in the computer or printer, not in the router.
When using a Linksys router, any fixed LAN IP address must be outside the DHCP server range (typically 192.168.1.100 thru 192.168.1.149), and it cannot end in 0, 1, or 255.
Therefore any fixed LAN IP address would normally need to be in the range of
192.168.1.2 thru 192.168.1.99 or
192.168.1.150 thru 192.168.1.254
assuming you are still using the default DHCP server range.
Also, in the computer, when you set up a static LAN IP address, you would need to set the "Subnet mask" to 255.255.255.0 and the "Default Gateway" to 192.168.1.1 and "DNS server" to 192.168.1.1
It is also important that no two devices on your network be set to the same static LAN IP address.

WRT160n Port Range forwarding problem

I have a WRT160n that I am trying to forward some ports on for some DVR equipment. When I use the single port forwarding and enter each port separately it works fine. But I have 2 DVR's and they use a bunch of ports each so I want to use the port range forwarding because there are not enough spots in the single port forwarding section. The ports I am trying to forward are 8000-8004 for one IP address and 8005-8009 for a second IP address. I have entered it into the port range forwarding section but I can not connect from outside my network. As I said if I enter them in the single port section seperately as 8000,8001,8002,8003,8004 then I can connect fine outside my network. Any idea's what the problem is?

How about you isolate it first by forwarding the ports for one DVR. Forward them one by one on the Port Forwarding Range page then see if it works on one DVR. If it will, try to do the same thing for the other DVR.
Yes I already tried this with no luck. I tried just opening one port in the port forwarding for 1 DVR and it did not work, Opening this same port in the single port forwarding did work.
Is your router a version 1,2, or 3? Your router probably needs to be updated (firmware).
Firmware
11/08/2010
Ver.1.02.11

3.15 MB

Ver.3.0.03 Build 3

And then reset and reconfigure your router again for internet connection and try the port range forward again and see if you can both DVRs working properly.

Port Range Forwarding Problem for E3000 and Iomega HMNHD Cloud

I'm trying to set up an Iomega Home Media Network Cloud NAS and I'm having problems with opening ports 50500-50599. I have opened port 80 and 443 successfully and included the above port range above as well, but when I check it on www.yougetsignal.com the ports 50500-50599 are still closed. I even tried to split the range in two parts, and still no success. I have been in contact with my ISP and confirmed they do not block any ports in the 50500-50599 range and that the cable modem (a Motorola SBV5120) is operating in Bridge Mode.
I am operating under an older firmware and hope that is not the cause of this problem. Also, using Win7 and Vista (tried and failed on 2 laptops).
Did I forget anything? Any suggestions/solutions? Thanks.

You may want to check out the list of tested hard drives to work with this router first. The link is E3000 and E2100L hard disk compatibility list. Based on the list, your iomega home media is not included. On the link for the tested hard drives to work with E3000, it is indicated that if your hard drive is not on the list, it may or may not work. With your case, since it is not working it may be due to compatibility issue.

I will Paypal you $100 if you can resolve this Port Forward problem

Believe me when I tell you, If you are the person who fixes this problem, I will GLADLY Paypal you $100.
This is so unbelievable. Short story is, after 12 hours of paid support through Support RIX, 6 hours with TWC support, and 4 different modems there isn't a single person in these groups that can get ports forwarded on my Linksys E4200 router.
I am running a fresh copy of windows 7 with all updates and no anti virus installed. I purchased a Motorola ARRIS SURFboard modem 200 series DOCSIS 3.0 so I have no double router issues. Before I was using the TWC moden/routers in bridge mode.
I have no problem setting a static IP or configuring port forwarding. It doesn't matter if I have windows firewall on or off. I can't get an outside port checking website that can verify an open port.
I am trying to play Battlefield 4 using the port forwarding request they provide.
If I run a local port check program on my computer it will confirm the ports open. Ok, Fair enough. They tell me the outside port checking utilities will say the port is closed unless I am running the program that uses these open ports.
SO I run the game and check and it always says port closed. One of the ports I want to open is 80. It has to be open to get internet anyway but it still shows closed using the online port checking websites.
I connected the computer to the modem. No router. I keep getting ports closed or filtered when I check through 6 different port checking sites. Leads me to think their is some kind of block in the ethernet card software.
Its a Realtek PCIe GBE Family controller with a driver date of 8/26/2014. Latest one I could find.
I think its an ethernet card filter. Just my thoughts. Here is the current adapter card settings.

I used a port tester downloaded from PCWinTech.com v3.0.0. It says the ports are open. When I close port 80 it says port 80 is closed. My problem is nothing outside my network can confirm an open port. It always states port closed.
The game I am playing is Battlefield-4. I have played all of the campigns without any problem but once online it crashes. The BF-4 community says I need to open 5 single ports and 5 port ranges. This is what I am trying to do.
We have tried an ARRIS router modem, a Ubee router modem (both in bridge mode) and are now using a motorola modem. All with the same problem. We checked the ports during game play and they all say closed.
I will post pictures of my current router settings.

What model router do you have?
What Firmware version is currently loaded?
What region are you located?
What is your current model ISP modem your using now?
What ISP Modem service link speeds UP and Down do you have?
Check cable between Modem and Router, swap out to be sure. Link>http://en.wikipedia.org/wiki/CAT6 is recommended.
Check ISP MTU requirements, Cable is usually 1500, DSL is around 1492 down to 1472. Call the ISP and ask.

Router and Wired Configurations
Setup DHCP reserved IP addresses for all devices ON the router. This ensures each devices gets its own IP address when turned on and connected, eliminates IP address conflicts and helps in troubleshooting and maintain consistency for applications that need to connect as well as mapped drives.
Ensure devices are set to auto obtain an IP address.
If http://en.wikipedia.org/wiki/Ipv6 is an option on the router, select Local Connection Only.
If you set up port forwarding, disable uPnP and test.
When you check for port status, you have to be actively using the port before you scan check as you may get a false negative if your not using the port. If your using the port then check the status, you should get an accurate result.
I would try using Port Range Triggering instead of PF and set up the port as follows for your PC that your gaming with:
0 thru 65535. A bit less hassle to set up then all those different port rules.
PC 3rd Party Security Software Configurations
Turn off all anti virus and firewall programs on PC while testing. 3rd party firewalls are not generally needed when using routers as they are effective on blocking malicious inbound traffic.
Turn off all devices accept for one wired LAN PC while testing.
Disable any downloading client software managers, i.e. Torrents or similar.

Can't run form from Form Builder 10g - Port configuration problem?

Hi,
I have installed the Database (10.2.0.1.0) and the Developer Suite (10.1.2.0.2) on two Linux machines (Red Hat Enterprise Linux ES 4 Basic).
If I enter the frmservlet-URL manually everything seems to be fine.
In one case I enter http://127.0.0.1:8890/forms/frmservlet, in the other http://127.0.0.1:8889/forms/frmservlet; in BOTH cases I get eventually a dark square and the status bar says "Applet oracle.forms.engine.Main started".
HOWEVER, if I create a simple form with Form Builder and click on the Button with the green traffic light ("Run Form"), the form runs only on the machine where frmservlet listens on port 8890.
On the other machine (frmservlet configured to listen on port 8889) Firefox pops up, the URL "http://127.0.0.1:32979/6dOrpwghCqnp8PhMT7KVT533m3IaArqFbPqPBOztZXWYSsNy" gets called, and nothing else happens. The screen displays the string "ORACLE FORMS." and the status bar says "Waiting for 127.0.0.1...", and it stays like this forever.
I assume this is a port configuration problem, but I don't have a clue where to start.
Any suggestions how I should proceed are greatly appreciated.
Thank you very much in advance!

Hi Frank,
Thank you for your reply.
I doublechecked my configuration.
In the dialog Edit --> Preferences --> Runtime the Application Server URL is set to "127.0.0.1:8889/forms/frmservlet".
However, when I attempt to run the form, the URL "http://127.0.0.1:33140/W2dwbV9eXS2fPkuKlxNhCxFWdEihwDviat2uV7ycrSotqwDN" gets called.
The screen displays the string "ORACLE FORMS." and the status bar says "Waiting for 127.0.0.1...", and that's it.
I wonder how the port number 33140 got selected. Interestingly, this time it is a different number; last time it was port 32979. In fact, the port number seems to change each time; I tried again and now it is 33189.
I will now try to set the port number for the frmservlet to 8890.
I choose Edit --> Preferences --> Runtime and set the application server URL to "127.0.0.1:8890/forms/frmservlet".
I stop the container, open /home/oracle/OraHome_1/j2ee/DevSuite/config/default-web-site.xml and change the port number to 8890:
<?xml version="1.0" standalone='yes'?>
<!DOCTYPE web-site PUBLIC "Oracle Application Server 10g XML Web-site" "http://xmlns.oracle.com/ias/dtds/web-site.dtd">



<web-site port="8890" protocol="http"
display-name="Oracle Developer Suite 10g instance of Oracle Containers for J2EE Web Site">

     
     
     <default-web-app application="default" name="defaultWebApp" root="/j2ee" />

<web-app application="forms" name="formsweb" root="/forms" />


<web-app application ="reports" name="web" root="/reports" />
<web-app application = "reports" name="demo" root="/repdemo" />
     
     <access-log path="../log/default-web-access.log" />
</web-site>
I restart the container, start Form Builder, connect to the database, and open my test form.
When attempting to run the form, the URL "http://127.0.0.1:33437/Pl0n3ky9vmU5z37A7ScBnQhsGwq3jwuzJpgTAKWPMOYIzT8K" gets called (again a new port number, apparently picked radomly within a certain range) and nothing happens: "Waiting for 127.0.0.1...".
However, when I enter the URL http://127.0.0.1:8890/forms/frmservlet I do (eventually, after confirming that I trust the certificate etc.) get a darc rectangle and the status message "Applet oracle.forms.engine.Main started", which tells me that my setup can't be that far off target.
Here is the output of netstat:

OC4J_BPEL no port available from the port range

To All,
We could not start our BPEL Process Manager and OC4J_BPEL. We have shut down and restarted the Linux server repeatedly and re-running the IRCA. All stacks are running except the OC4J_BPEL and BPM.
We keep receiving the following message when we start the BPM:
BPEL Process Manager
OraBPEL : OC4J_BPEL no port available from the port range
OraBPEL : OC4J_BPEL - failed to start a managed process after the maximum retry limit
OC4J_BPEL
OraBPEL : OC4J_BPEL no port available from the port range
OraBPEL : OC4J_BPEL - failed to start a managed process after the maximum retry limit
Our OraBPEL is on a single HP NetServer LH6000 with Red Head AS 3.0, Oracle 10g DB and AS middle tier all in the same machine. The server was running a batch BPEL process. After running 2 hrs and process 12,000 records it was brought down by a single runtime exception. We were able to bring back the Oracle 10g AS middle tier but not the OC4J_BPEL instance. Any help would be appreciated.

I changed the OC4J_BPEL port from 3201 to 3211 fix the problem. It was conflicted with the home instance that is using port 3201. However that still can not get rid of the OC4J-BPEL failed to start a managed process after the maximum retry limit.

ACE FTP inspect with port range

Hi everyone,
I have a problem with passive FTP with fixed port range.
I configured a ftp server with a fixed port range of 60000 - 60500 for the data channel.
And the ace is configured with "inspect ftp" on policy of ftp-serverfarm.
A tcpdump on server I can see that the server uses the portrange in response packet.
(x,x,x,x,34,195) = 60099
But on client I can see that the port on packet is change to another port. The ace is between server and client.
On CCO I found a document "http://www.ciscosystems.com/en/US/docs/app_ntwk_services/data_center_app_services/ace_appliances/vA1_7_/command/reference/policy.html#wp1006925" ->> Enables FTP inspection. The ACE inspects FTP packets, translates the address and the port that are embedded in the payload, and opens up a secondary channel for data.
I don't understand why the ace change the port in ftp payload.
Is it possible to create the same port range on ace configuration of connectio to client?
Thanks
René

You don't need inspect ftp with one server because you can avoid it.
You can for example configure a loopback on the server with the vip address and configure the serverfarm as transparent on ACE.
Then for the data channel, since your range of ports is quite small, you can catch it with a class-map and simply forward to the server.
Like this, the server will use the vip address in all packets exchange with the cleint (no need to nat the payload) and when the client opens a data connection, the traffic is matched with the class-map and the connection can be forwarded to the server using the same transparent serverfarm.
Less chance to run into compatibility issue.
Better performance since we can switch traffic with inspecting its content.

The router forgets Port Range Forward settings

Hello, after a year or so of working absolutely flawlessly, the router, all of a sudden, started forgetting the Port Range Forward settings. In particular, I have port 80 set to go to a specific IP address. Every now and then, it will start going to a different address within the network (even though the Port Range Forward page still shows it pointing to the right IP address).
I disable Port Forwarding for that port, then re-enable it and everything is fine. For about day or two and then the problem re-appears.
What could be the issue?
Thanks.

What is the model no of the Router...?
Who is your ISP...?
What firmware you are using on the router...?
Try to reset the router and re-configure it from scratch.Now,check if that make any difference.

Net 8 Port Range

I have Oracle 9i installed on a Solaris machine. There is an
Application server in the DMZ which is required to connect to
the Oracle 9i machine via the CheckPoint firewall machine.
Therefore, I need to add a rule in the firewall to let it go.
The default listening port for Net 8 is 1521. I found that the
port number used by Net 8 after authenticated is varied. Please
advise the port range used by Net 8, thanks.
SK

I do have the same problem and I guess the solution (using the firewall, not a VPN) is to set a range o high ports into the firewall and try to limit the response from Oracle to this range.
How can we set a range o high ports response into Oracle? I am using 8i.
Best Regards,
Rodolfo

"assert" a port range

i am trying to use "assert" more often.
a simple application would be with port ranges:
(1) in unix the max. priviledged port sets the lower
bound of user specifiable ports. but i don't think
this is platform independent?
(2) what is the maximum allowable port number?
i found this: 32767
thanks.

some advice: don't use assert. and, when i say this, i don't mean "don't verify your code", i mean, don't use the assert keyword. the problem comes from the fact that many checks that are asserts should really just be if blocks which throw runtimeexceptions (code that should always be enabled). and, if you have that kind of code using asserts, then you're never going to want to turn them off in production, and then, what's the point in the first place? if you are going to use asserts, i'd recommend only using them in code which is performance intensive (which you know you want turned off in production), and just use normal checks for everything else.
as for your actual question, i think 1024 tends to be a "standard" for the max privileged port number.

Tuxedo Application port range

Hi All,
Is there any way to restrict tuxedo application to use a specified range of ports while it is up & running (except JSL, WSL, GWTDOMAIN) ?
Issue - The tux application comes up with random ports getting assigned to the application servers connecting to the DB, which at times occupy either of WSL, JSL, NWADDR of other tuxedo application that's scheduled to come up later on the same box.
I am looking for a way to restrict the first tux application coming up within specified port range for the servers.So they don't overlap with other tuxes (WSL,JSL,NWADDR).
Thanks in advance.

Hi,
OK, now I'm really really confused. DB ports as specified in tnsnames.ora or somehow through the OPENINFO string are destination ports, i.e., ports that some Tuxedo process will be connecting to. Server ports, i.e., ports that a local process opens for listening are only done by Tuxedo system servers such as the JSL, WSL, GWTDOMAIN, GWWS, etc. Although you can have multiple Tuxedo SHM (or MP) domains on the same physical host, they cannot share TCP/IP ports. That's a fundamental limitation of the socket implementation on most (all?) operating systems.
Normal application servers, i.e., server built with the buildserver command don't ever open up listening ports. All communication to application servers is done via System V IPC queues. The only servers that listen on network ports are Tuxedo system servers, and all of them have configurable network addresses, including host and port. So the JSL, WSL, GWTDOMAIN, etc., all can be configured to listen on specific host/port addresses.
Regarding net.ipv4.ip_local_port_range, this is an OS parameter and not a Tuxedo parameter. Tuxedo servers just listen on the ports configured in whatever configuration file is appropriate, i.e., WSL and JSL in UBBCONFIG, GWTDOAMIN in the DMCONFIG file, GWWS in the imported WSDF files. For outgoing connections such as to the database, the source port for those connections is under the control of the operating system. They should never conflict as the OS allocates free ports for each connection.
Perhaps you can tell me what it is you are seeing that you would like to see behave differently so I can get a better feeling for what the problem is. There should never be a port conflict assuming your Tuxedo network address are configured uniquely across whatever domains are on a specific host.

Port Range Already Exists warning - WRT310N

Attempting to forward a range of ports, when I save the settings, I get the error "port range already exists". Doesn't matter what number I put in there or how wide the range is, any thoughts? Has the latest firmware (that I'm aware of; v1.0.07-LS-HND). Hard to find any posts on this but I think there was a similar problem with Single Port Forwarding also if you used the 5 built-in settings.
Thanks,
Ron

Make sure the LAN IP addresses (that you are trying to forward the ports to) are outside the DHCP server range, and that they do not end in 0, 1, or 255.

Nexus1000v : ip access-list with port range

Hi,
I am configuring ip access-list policy with port range on Nexus1000v. I want to block traffic of a VM based on specific port or port range. Following is the example showing, blocking of rdp service (port - 3389) of vm x.x.x.x. But the scipt blocks all traffic of x.x.x.x.
Can any body verify the scirpt and tell whats the problem with the script?
vm x.x.x.x is on Veth2
config t
ip access-list Veth2_rc_vmfw_acl_in
deny tcp any host x.x.x.x eq 3389
exit
ip access-list Veth2_rc_vmfw_acl_out
deny tcp host x.x.x.x any eq 3389
exit
interface Veth2
ip port access-group Veth2_rc_vmfw_acl_in in
ip port access-group Veth2_rc_vmfw_acl_out out
exit
exit
Thanks

What's safer: Port range forwarding or Upap?

Hello there,
I recently replaced my router and since then have been unable to get video and audio chats to work. I get the "XXXXX did not respond" message. Text chat is fine. By what I have read in this forum, my problem has to do with port settings on my new router, a Linksys wrt54gx2.
My question is this; is it safer/more secure to use port range forwarding or the universal plug and play option? Do I need both?
The Mac OS X firewall settings are currently off.
Thanks in advance for any advice.
John

HI John,
This is not a suitable device for iChat for some reason.
This page is for the WRT54GX (not the GX2)
This shows the Port Forwarding for this device (and the default IP and User ID and Password).
You should not use Port Forwarding and UPnP together.
The UPnP setting in in the Admistration tab.
Port Forwarding uses NAT (Network Adress Translation) and this can cause problems between some devices.
UPnP does Broadcast that is available but is normally limited to a few Hops.
In most device this can be limited to just one hop if you require.
