How to determine IP address of client request in CORBA

Hello
does anyone know of a way to determine which peer is making the invocation of a method in CORBA?
I need to find a way to determine the IP address of the calling peer, but at the server-side and NOT by passing the IP address as an argument with a method invocation like the following method:
void foo(in string ipAddress);
The above method declaration is in the .idl file.
Thank you in advance

There's no portable way to do this and I don't know if / how it's possible with the Sun ORB (the one available in the J2SE).
It is possible with the latest versions of JacORB (www.jacorb.org) - a free LGPL Java ORB. The feature is undocumented (as yet) but if you can decompose unit test code you can see how it works in the code in this directory:

I have a similar chat application. When the user attempts to connect, instead of sending a simple string, the client sends a serialized object(xml string) with all relevant login and session information, this includes the user's IP address. Once the server
receives said information, depending on the type of TCP broadcast (a custom enumerated type) information from one user may be passed to a single user, or distributed to many users.
If it helps, here is the TCPBroadcast object I use. But in order for your server to understand it, you kind of have to build your server and client somewhat around it.

How to determine the address of the server whence the application through W

The application is loaded from the server taking place in Intranet networks. How to determine from this application the address of the server with which it it is loaded?

Use could use the javax.jnlp BasicService.getCodeBase(). See http://java.sun.com/j2se/1.5.0/docs/guide/javaws/developersguide/examples.html and http://java.sun.com/j2se/1.5.0/docs/guide/javaws/jnlp/javax/jnlp/BasicService.html

How to get MAC address from client machine ?

Hi dear,
We are implementing security measures for a banking system, so it is required that we track the MAC address of the registered clients along with other parameters. How do we get the MAC address from client machine using ADF or running scripts in client side?
thanks all

Hi,
Welcome to OTN.
Your question has nothing to do with ADF as such. Googling would give you plenty of such topics.

How to determine IP address in stored procedure ?

Hello :)
I want to determine caller's IP address from a stored procedure without having to receive it as parameter.
Thanks in advance

you can use sys.dm_exec_connections
SELECT client_net_address, *
FROM sys.dm_exec_connections
WHERE session_id = @@SPID

How to determine the size of client in sap system

Dear Exports,
Pls suggest me how we can check the size of the client in oue sap system.
Thanks in advance.

Hi Amit,
If you are not able to check the note 118823 or you can't able to find the solution. Just start client copy in test mode, there you can get the size of the client then you can cancel the client copy(which is in test mode).
Hope it will resolve your doubt.
Thanks

How to determine the Servlet which current request is mapped to

Hello folks,
having a filter, i want to discover the servlet (if any) which will serve the current request. I want to have it before the chain execution. Does someone has an idea how to accomplish this using Servlet API? The old API provided the getServlet(String name) method for this task. Here the sample code:
Servlet servingInstance = discoverServlerForRequest(request); //i look for implementation of this method
chain.doFilter(request,response);I know that it would be very easy to get the servlet AFTER processing the chain, but the clue for me is to get it before.
Maybe Tomcat has implemented some special servlet context attributes to map it?
any hint appreciated!
thanks

its possible, for sure. but then I need two filters to achieve it. I'll post my solution later, if there wont be any other ideas. I know that tomcat maps many objects by attributes...maybe there is a key for it.

How to determine IP addresses of machines on network?

Is there a way to view a table of all the machines (computers, printers, whatever) on the network? I need an IP address of a print server and have no idea how to find it. On my old Linksys router, it provided such a table. Any way to on the AirPort Extreme?

Hallo David
Maybe the "arp" command might help you.
Open a terminal and enter
arp -a
It should print out a list of IP addresses that are wired
to the MAC addresses of all ethernet adapters in your network.
This does only work in you local network segment, not crossing any routers.
It might require "sudo arp -a", but printing out the table usually does not.
Have a nice christmas holiday,
Patrick

How to trace IP address ports and request comming to network interfaces

Did you find a solution?? If still looking, talk to Triometric, they can monitor and log this, a side effect of performance monitoring.

How to determine using MDM rich client OR thin client?

We want to save but also want to make sure nothing missing
SO could you tell me how to decide rich client or thin client?
Thanks!

Hi Jessica,
MDM Rich Clients: A rich client is a networked computer that has some resources installed locally (MDM Components) but also depends on other resources distributed over the network (MDM SERVER). It Provides rich functionality.
e.g MDM Components (MDM Console, MDM Import Manager, MDM Data Manager and MDM Syndicator)
MDM Thin Clients: If a user only needs to perform select tasks and does not need all the functionality of a standard computer or program, a thin client may be the right tool for the job. e.g. SAP Enterprise Portal (Iviews for Search and Read access)
You can verify that MDM Components are Rich clients and SAP Enterprise Portal is a Thin client on page 4/41 Components in a MDM landscape as given in below link:

How to determine ip address as static or dynamic

hi, im trying to figure out ways of testing incoming ip connections to my mail server as dynamic or static, would a simple get canonical name tell me this?
any adivce would be greatly appreciated
thanks

Whether an IP is static or dynamic, it is just a decision of the IP administrator / owner. There is no technological measure in finding out such a human decision.

IP address of client of webdynpro application

Hello,
is it possible to determine IP address of client from webdynpro application?
Thanks in advance.
Zdenek Smolik.

Hi Stefan,
We have developed application which is able to interactively update saplogon.ini file according to users needs. User can select systems which should be visible in saplogon offer. Because aplication backend has to connect to client's machine it needs to know its IP address. Because we have used webdynpro as user interface (backend is in R/3) we need to determine client's IP address here.
I have made a workaround using Java servlet but I am interested in possible webdynpro solutions.
Thanks and Regards
