Dynamic port assignments

hi all. if my question can be answered by reading TMG documentation, feel free to direct me there (i tried searching for the admin documentation but couldn't find it).
can someone tell me what the purpose of dynamic port assignment is from endpoint -> TMG? Once the traffic leaves the TMG -> Internet, the actual service port is being used but that doesn't help me for internal queries.
many thanks,
-P

Notes
This port is not used with ISA 2000.
FWC application transport and protocols are negotiated within the FWC control channel.
ISA 2000 FWC control uses UDP. ISA 2004 and 2006 use TCP.
OEM uses Firewall Web Management to provide non-MMC management of ISA Server.
This port is also used for intra-array traffic.
This port is used only by the ISA management MMC during remote server and service status monitoring.
This is the range in TMG. Please note that TMG extends the default dynamic port ranges in Windows Server 2008 R2, Windows 7, Windows Server 2008, and Windows Vista.

Dynamic VLAN assignments with ACS

Hello all.
I am trying to do dynamic vlan assignments with dot1x auth. I am using ACS5.3 and Cisco 3560.
I have configured them correctly to the best of my knowledge but it doesn't seem to be working correctly.

However "show int status" still shows the port on vlan 1 and the end device is stuck with a 169.x.x.x address (Windows PC).
Any idea what config I'm missing?

Dynamic port configured for FILE adapter is not working

Hi,
I have a simple dynamic port in an orchestration that writes a file to a file location. Here is the configuration
================
FilePort(Microsoft.XLANGs.BaseTypes.Address) = "FILE://c:\\TestFolder\\Out";
FilePort(Microsoft.XLANGs.BaseTypes.TransportType) = "FILE";
================
When I run this orchestration, the dynamic port does not write the file to the folder, however I does not show any error either. It is always in "Ready to Run" state where the message is "Queued Awaiting".
I tried all sorts of combinations like FILE:// FILE:\\ File: file:// file:\\ etc... and also without the moniker, just c:\.... I get the same problem.
when I use a static port(subscribed to the same message) it works fine. When I use a static port ALONGWITH this dynamic port then both works fine !!! I receive 2 files.
but when I use only dynamic port it does not work!!
Anybody knows how to solve it.
THANKS IN AVANCE
PLEASE HELP
Surya

It could be becasue you 're not passing in the file name, Try something like this..
SndPort_Dynamic(Microsoft.XLANGs.BaseTypes.Address)=@"file://C:\Test\Try\Out\Test1.xml";
But even when you don't pass the file name, i was expecting the erro to be like:
The FILE send adapter cannot open file C:\TestFolder\Out\ for writing.
Details: The system cannot find the path specified.
But try with File Name and restart the host instance after the change.
Or use somehting like this:
FilePort(Microsoft.XLANGs.BaseTypes.Address)=@"file://C:\Test\Try\Out\\%MessageID%.xml";
FilePort(Microsoft.XLANGs.BaseTypes.TransportType) = "File";

Sql server 2012 express - tcp/ip connection to named instance using dynamic port not working

I have a named instance on a SQL 2012 Express server that won't connect via TCP/IP when wanting to connect off of the dynamic port. I can connect via shared memory locally on the server.   I can connect to the namespace when specifying the
dynamic port listed in the configuration manager.
This is the only named instance on the server and it is not the default.
TCP/IP is enabled
Allow Remote connections is enabled
the server browser service is running
I can connect via the dynamic port number
I am testing the connection locally on the server, so I don't believe a firewall is the issue. I get the same results if I test it from a remote computer.
When using the sqlcmd (sqlcmd -S tcp:SQLSRVR\NAMEINST -E) I get the message that "the requested protocol isn't supported [xfffffffff]".   The command (sqlcmd -S tcp:SQLSRVR\NAMEINST,59992 -E) works.
Through SSMS, I get the message "the connection was actively refused".
On other boxes, I can connect with the named instance without having to specify the port.
I have looked through the sql logs and nothing much shows up. The log does show that is listening on the port # for ipv4 and ipv6.   There is also a line in there talking about the SPN not being registered and not to worry about it if
you are not using Kerberos. I logged in through shared memory and it said I was using NTLM.
Any help would be appreciated.
thanks.

Hi clw,
I’m writing to follow up with you on this post. According to your description, I do a test, if you configure the database engine to listen on a specific TCP port (59992), and
the port is opened in the firewall. If you want to connect to the SQL Server instance, you 'd better to
use the port number.
In my opinion, by default, the default instance of the Database Engine uses port 1433, usually, if you have configured the server to listen on a non-default port number, when an instance of SQL Server uses dynamic port allocation, the connection string that
is built at the SQL Server client does not specify the destination TCP/IP port unless the user or the programmer explicitly specifies the port. Therefore, the SQL Server client library queries the server on UDP port 1434 to collect the information about the
destination instance of SQL Server.
If UDP port 1434 is disabled, the SQL Server client cannot dynamically determine the port of the named instance of SQL Server. Therefore, the SQL Server client may be unable to connect to the named instance of SQL Server. In this situation, the SQL Server
client must specify the dynamically allocated port where the named instance of SQL Server is listening.
For more information about configuring an instance of SQL Server to listen on a specific TCP port or dynamic port, you can review the following article.

Using BC4J Session Bean in OC4J 10.1.3 with dynamic ports

Hi Folks!
I've benn having trouble connecting my BC4J Session Bean to an Oracle 10gAS R3 server instance tha uses dynamic ports.
After migrating a BC4J/Struts/JSP application from 9iAS to 10gAS R3, I'm trying to connect from a client application to my instace in the server. The problem is that the instance uses dynamic ports, and whenever I deploy my application to the server, I've got to update the port number in the bc4j.xcfg file in the client application, wich has became impossible to maintain.
When I connect to an EJB in the same server, I use the instance name instead of the port number. However, when I do the same with BC4J, I get the following exception:
javax.naming.NamingException [Root exception is java.lang.NumberFormatException: For input string: "OC4J_dvt20"]

My question is: is there a way to configure my bc4j.xcfg, or another way to connect, in order to skip the use of the port number? Or a way to get the port number from the server before I connect?
Thanks in advance!!!

I've just found the solution from Steve Muench weblog, always useful by the way!
You can find the solution at this link http://radio.weblogs.com/0118231/stories/2004/05/07/handcodingDynamicDiscoveryOfEjbdeployedAppmodule.html
In summary, we need to use the class com.evermind.server.rmi.RMIInitialContextFactory, which supports dynamic lookup, and implement the lookup ourselves.
The code I've written to lookup the service is listed below:
public static ApplicationModule getAppModuleManutencao() {
try {
Context ctx = getContext();
ManutencaoFacadeHome home = (ManutencaoFacadeHome) ctx.lookup(EJB_MANUTENCAO_BEAN_NAME);
ApplicationModule am = ApplicationModuleProxy.create(home, null);
return am;
} catch (NamingException nex) {
nex.printStackTrace();
return null;
private static InitialContext getContext() {
try {
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.evermind.server.rmi.RMIInitialContextFactory");
env.put(Context.SECURITY_PRINCIPAL, "admin");
env.put(Context.SECURITY_CREDENTIALS, "welcome");
env.put(Context.PROVIDER_URL, "opmn:ormi://dsv008:OC4J_dvt20/mct");
env.put(Context.SECURITY_AUTHENTICATION, "simple");
return new InitialContext(env);
}catch (NamingException e) {
e.printStackTrace();
return null;
I hope this helps someone!!!
Cheers!

Dynamic ports and firewall?

Hello:
I'm running a firewall and want to back it up using OSB. I'm trying to find out the range of dynamic ports that OSB uses (in addition to 400 and 10000) so I can open them up.
I can't find it anywhere in the documentation. I only find this reference as part of the Windows installation section:
If your Windows host is protected by a firewall, the firewall must be configured to permit Oracle >Secure Backup daemons on the host to communicate with the other hosts in your administrative >domain. Oracle Secure Backup includes daemon components that listen on ports 400 and 10000, >as well as other dynamically assigned portsWe can allow full access from our backup server to all ports on the firewall, but that is NOT a preferred solution! :-)
Thanks!

The range of port numbers should be above 20,000 but below 32,000 (ie 20,000 - 20,024) in addition to ports 400 and 10000.
The number of ports needed is calculated by multiplying the # of concurrent OSB activities by 5. Or, by the # of tape drives (inside the firewall) and the # of clients (outside the firewall).
Steps:
1) On Firewall, open desired range of ports plus 400 and 10000.
2) Edit the /etc/services file on both the admin host and the client to use:
ob-daemon-low <port low #>/tcp
ob-daemon-high <port high #>/tcp
These parameters are based on ports you select for OSB (from step #1 above).

FlexConnect, EAP-TLS and dynamic VLAN assignments

I need to integrate Cisco ISE and WLC5508 with FlexConnect (local switching) using EAP-TLS security for wireless clients across multiple floors (dynamic VLAN assignments based on floor level). The AP model used is 3602.
I have some questions:
- What RADIUS Attribute can be used for dynamic VLAN assignments based on floor level? Is there an option where I can group all LWAPs in same floor for getting certain VLAN from ISE?
- I intend to use WLC software version 7.2 since 7.3 is latest version. Has someone use WLC software version 7.3 without any major bugs/issues pertaining to FlexConnect and EAP-TLS?
- I read some documents saying L3 roaminig is where the associated WLC has changed. However if user move to different subnet but still associated to the same WLC, would this be consider as L3 roaming too?
Can someone assist to clear my confusion here? any reference url for layer 2 and layer 3 roaming details is appreciated. Thanks

I'll give this a shot:)
For radius vlan attributes, bothe ACS and ISE in the policies have the ability to just enter the vlan id in the profile. You can either do that or use the IETF attributes.
The RADIUS attributes to configure for VLAN assignment are IETF RADIUS attributes 64, 65, and 81, which control VLAN assignment of users and groups. See RFC 2868 for more information.
64 (Tunnel-Type) should be set to VLAN (Integer = 13)
65 (Tunnel-Medium-Type) should be set to 802 (Integer = 6)
81 (Tunnel-Private-Group-ID) should be set to the VLAN number. This can also be set to VLAN name if using a Cisco IOS device (excludes Aironet and Wireless Controllers however).
You can find this by searching on Google.... A lot of examples out there
v7.2 and v7.3 I have had no issues with, with any type of encryption used. With 7.0 and 7.2, I would use the latest due to the Windows 8 fix.
Layer 3 roaming is what's going to happen if the AP's are in local mode. This means that the client will keep their IP address no matter what ap they are connected to and or WLC as long as the mobility group is the same. So a user who boots up in floor 1 will keep its IP address even if he or she roams to the 12th floor and as long as he or she didn't loose wireless connection.
FlexConnect you can do that. The AP's are trunked and need to have the vlans. So what your trying to do will be disruptive to clients. When the roam to another floor ap that is FlexConnect locally switched, they will drop and have to re-associate in order to get a new IP address.
Hope this helps.

IE10&11 Dynamic port usage.

Hello
Since we upgraded to IE10 on a 2008 R2 terminal server we're getting the error "This page cannot be displayed" After a few minutes it would start working again, I was able to reproduce the error by going to a site with a lot of images, like google
maps for example. I performed a netstat and saw that IE was using 100's of ports, it appears to open a new port for every connection to the remote server. As a result I think that with 10 or 15 people on the terminal server browsing the internet, the server
runs out of dynamic ports. Is there any way to make IE10&11 reuse TCP connections rather than opening new connections to the remote server, or a way to restrict the amount of ports it uses?
During testing I found that IE9, Firefox and Chrome do not act this way.

IE uses port 80 for browsing. If you need something specific that's not allowing your URL's to work, i would suggest you to capture the network traffic and check where the link is getting dropped.

Doing FTP using a Dynamic Port

Hi,
I am having an odx with a Receive Shape, expression and Send shape.
The send shape is connected to a dynamic port:
There is a message var called ShowPartMessage.
There is no transformation. This message needs to be received and sent via FTP.
In the expression shape i have something like:
SendPortName(Microsoft.XLANGs.BaseTypes.TransportType) = "FTP";
SendPortName(Microsoft.XLANGs.BaseTypes.Address)= @"FTP://99.99.x.xxx/fold1/ftp/%MessageID%.xml";
ShowPartMessage(FTP.UserName)= "user";
ShowPartMessage(FTP.Password)= "pass";
I get an error message for the last 2 lines saying "message construction must be done
in a construct block".
Do i need a construct block just to assign the username and password?
i based my soln on the following link here:
http://msdn.microsoft.com/en-us/library/aa560663.aspx
Please assist
regards,

The difference between static and dynamic ports is only the Message Assignment shape, which is mandatory in a dynamic port to specify the FTP port details.
Your message assignment shape should have the code like below:
Msg_DynamicSend(FTP.CommandLogFileName) = "D:\\BiztalkLogs\\FTPLog\\DynamicFTPLog.txt";
Msg_DynamicSend(FTP.UserName) = "FTPUSER";
Msg_DynamicSend(FTP.Password) = "Pass1234";
Msg_DynamicSend(FTP.SpoolingFolder) = "/IN/";
Msg_DynamicSend(FTP.RepresentationType) = "ASCII";
DynSendPort(Microsoft.XLANGs.BaseTypes.Address)= "ftp://inhydeshrilata";
DynSendPort(Microsoft.XLANGs.BaseTypes.TransportType) = "FTP";
Msg_DynamicSend is the message name set for send port and DynSendPort
is the port name for dynamic send port.

Does APPS have dynamic port allocation going on somewhere

Hi Gurus,
We have a situation where 5 Test instances of Ebiz all reside on the same server. The production Instance has its own dedicated server.
We seem to get intermittent, but frequent problems with some of the test environments taking the ports which are defined for other environments in the xml file.
This issue Never occurs in production
All environments services are restarted every night - most of the time there is no problem. But sometimes, web, forms, apps listner or concurrent managers wont start - an they give errors due to locked ports.
When I run a netstat -anp | grep <port> - the output shows that one of the other environments is listening on the port in question.
I have made absolutley sure that in the xml files and httpd.conf etc - each environment has its distinct port set (which it does)
I have searched for ages on google and metalink to try to find information about dynamic ports but cant find any
Can anyone help?
Thanks

Hey Oli, no help here I'm afraid just wanted to say I am experiencing a similar problem although mine is a situation where I have e-Biz and OAS installed. The seem to co-exist peacefully most of the time but our app also restarts every night and some mornings the app is not available. Recently it was fixed by shutting down the OAS server and restarting.
So no resolution yet but I feel your pain. I was just starting to look into how I would use netstat to help my troubleshoot and also look at net.ipv4.ip_local_port_range set in /etc/sysctl.conf.

*2013-02-25 14:30:08 ERROR OGG-01201 Error reported by MGR : No available dynamic port entries.*
*2013-02-25 14:30:08 ERROR OGG-01668 PROCESS ABENDING.*
This is the same configuration that was working fine for many days:
GGSCI>ADD EXTRACT exp1, SOURCEISTABLE

GGSCI>edit params exp1

Thanks for your reply and time Kamal.
When i run :
GGSCI (smsc.etisalcom.net) 1> send mgr getportinfo detail
returns
Sending GETPORTINFO, request to MANAGER ...
No Dynamic Ports In Use or Configured
But I have tried with
DYNAMICPORTLIST 7809,7810,7811 7812-7850
But error message was the same.
Current settings for the mgr
GGSCI>edit params mgr
PORT 7813

CVP OAMP dynamic ports requirement

Hi all,
Based on CVP SRND
"Because the Unified CVP Operations Console Server uses dynamic ports for communication with other
components, it cannot be deployed outside of a firewall while the rest of the Unified CVP components
reside inside the firewall"
In an environment where we have Call Server 1 & OAMP (Site A) and Call Server 2 (Site B)
a) how would it be possible to comply to the SRND since Site A & B would definitely be separated by firewall?
b) what method / workaround can be used to allow communication between OAMP (Site A) and Call Server 2 (Site B)?
Thanks!

Hi,
I have a similar setup what you had descried. The firewall config is in such a way that it is IP to IP communication, where it would allow all the ports of Source and Destination. We have not come across any kind of issues so far
Hope this helps!!!
Thanks,
Dass

Dynamic port channel and load distribution across the interfaces on th trunk.

WS-C3750G-48TS
NOS-12.2(25)SEE2
I have a dynamic port channenl setup on Cisco+NetApp environemt where i have 6 interfaces(1Gbps) on that trunk for load balancing and reduntancy reason.
But i see the interfaces are not balanced on receives or inbound. I mean most of them are going to only 2 interfaces and other four are almost doing nothing.
I am assuming netapp ports serves the way how Cisco instructs. How i can remediate this situation? What am i missing here?

I have alerady mentioned "lacp" in my my last post. Also my understanding LB is set at switch side , not at filer side. Becase i dont have config at filer side. Also loooking the link there also dont see a config which says use a particular LB.But the article clearly says to use "ip load balace", no clue though where it is set. hence my question what is the default LB used/set at switch side. http://now.netapp.com/NOW/knowledge/docs/ontap/rel727/html/ontap/nag/7vifs3.htm https://communities.netapp.com/community/netapp-blogs/sanbytes/blog/2011/12/13/what-value-does-the-leading-fc-switch-vendor-bring-to-ethernet-guest-post-by-brocade http://blog.ioshints.info/2011/04/brocade-vcs-fabric-has-almost-perfect.html may be a good reads i guess.

Dynamic port use

My application uses RMI by having a server-proxy-service system to enable the classes on the user's side to access functions on the server side that access the oracle database.
I have recently been asked for a specification of the ports that our application uses.
I have run a "netstat" on my server and saw that the user's computers connect to the server on a dynamic range of ports, while the only interaction the users have with the server is via RMI.
Is RMI responsible for the connection of dynamic ports to the server?
If so, is there anyway to set it use only certain ports?

If so, is there anyway to set it use only certain ports?Yes. You can specify the port when constructing a Registry with LocateRegistry.createRegistry, and when exporting a remote object via the constructors of UnicastRemoteObject or UnicastRemoteObject.exportObject(). If you don't specify the port here, or specify zero, a system-allocated port will be used.
