Getting the caller address inside kernel

How to get the caller address inside a kernel ? I mean address of a kernel
function x, calling other kernel function y.
Currently I am doing the following to get the caller address inside a
kernel function(Sol7, 64-bit sparc). This is not wrong, but may be a
problem if we turn on compiler optimizations.
<PRE>
kernel_func_y(someargs_t *args)
int x;
/* get the caller address into args->cl_addr */
asm("stx %i7, [%i0 + 8]");
/* use the caller address, here for some reason */
some_operation(args->calleraddr);
</PRE>
Is there any DDI/DDK function/macro available to do this ? If not won't it
be nice to have such a DDI/DDK macro/function ?
Thanks

Hi Sini
Good question! I dont think there is any library which provides
this functionality. And yes it might be helpful under some special
circumstances. Although I think you might be able to get it from
the stack.
My 2 cents.

Getting the IP Address of an HttpURLConnection

I'm using an HttpURLConnection to fetch a web page, and would like to get the IP address of the remote computer that I'm fetching from. I know that I could simply call
InetAddress.getByName(hostName).getHostAddress()
first to resolve the domain name, but that's not going to work for me. The remote host has some sort of round-robin DNS system and I don't want to know what IP address the name "could" resolve to, I want to know what's the IP being used in the case where I call HttpURLConnection.connect().
It seems like the IP address is burried deep inside the abstracted layers. Any way to get at them?

Actually, not a bad question. It's kind of involved, so I'll give you the gist.
I'm automatically fetching some data from a URL that ultimately resolves into a big server farm. The software on the servers in the farm is being updated on an ungoing basis, and often different servers run different versions of the software as the updates roll out. One piece of information I fetch is the software's version number.
I'm trying to model how these updates are rolling out, so I set up some automated process around the world to grab this data from the URL periodically and watch how and when the version numbers change. One piece of information that would be valuable to have is knowing when I hit the same physical server twice, hence I need the IP address. Yes, I know that the IP address probably really represents a load balancer, but it does get me one step closer to understanding how the whole process of updating these servers works.
Hope this makes some sense.

How to get the IP address of printer USB attached to Time Capsule?

I'm trying to work a printing problem with my HP7310 Officejet and VMware's Fusion 2.0.3. I'm on Mac OS 10.5.5.
One of the first diagnostic steps for Fusion is to ping the IP address printer. If I open the Print & Fax dialog from System Preferences I can see the name of my printer, let's say it's called "foo bar". I then open a bash terminal and type: ping "foo bar", but get an "unknown host" message.
I can ping the Time Capsule itself by getting the IP address from Airport Utility. The printer "foo bar" shows properly in the Airport Utility Printers dialog.
Anyone have any suggestions?

If you open AirPort Utility > Manual Setup > Advanced > Logs & Statistics > DHCP clients, a list of the devices will be displayed with their IP addresses. Make note of these.
You will have to get the IP for your printer by process of elimination. Go to
System Preferences > Network to see your ethernet and wireless connections and associated IPs. You should be able to narrow the list down to identify your printer.

How to get the MAC address of a PXI in a dll

Hi,
I am looking for a way to get the MAC address of a PXI RT controller. I know that there is a VI to do this, but I am looking for a solution for a dll (C-Code).
I use the "Call library node" to call this dll and want to make sure that it is only used on a specific PXI.
Since the VI provides the functionality, I am wondering if it is also available to be called from C-Code?
Thank you,
Christian
Solved!

If it is available in LabVIEW it is probably available in CVI, which you could then build into a DLL (if there isn't one available already).

SAP Cloud For Customer How to Get the IP Address of Tenant

Hi Experts,
I need to know how to get the IP Address of our cloud Tenant ?
Can anyone know please tell me the process.
Many Thanks

Hi Mithun,
In my understanding there SAP will not share IP address of tenant. If this is really urgent you should discuss to SAP Partner coach or any other representative. SAP network team will not directly communicate with you, this will require numerous approval inside SAP itself.

Whenever I update my iPhone software, it asks me to sign in to iCloud with an old email address. My other devices all have the correct address. How can I get the correct address for my iPhone? The only Apple ID that works for logging in is my new one.

Whenever I update my iPhone software, it asks me to sign in to iCloud with an old email address. My other devices all have the correct address. How can I get the correct address for my iPhone? The only Apple ID that works for logging in is my new one.

To change the iCloud ID you have to go to Settings>iCloud, tap Delete Account, provide the password for the old ID when prompted to turn off Find My iPhone (if you're using iOS 7), then sign back in with the ID you wish to use. If you don't know the password for your old ID, or if it isn't accepted, go to https//appleid.apple.com, click Manage my Apple ID and sign in with your current iCloud ID. Tap edit next to the primary email account, tap Edit, change it back to your old email address and save the change. Then edit the name of the account to change it back to your old email address. You can now use your current password to turn off Find My iPhone on your device, even though it prompts you for the password for your old account ID. Then go to Settings>iCloud, tap Delete Account and choose Delete from My iDevice when prompted (your iCloud data will still be in iCloud). Next, go back to https//appleid.apple.com and change your primary email address and iCloud ID name back to the way it was. Now you can go to Settings>iCloud and sign in with your current iCloud ID and password.

How can I get the MAC address of my Apple TV?

How can I get the MAC address of my Apple TV? I currently do not have an HDMI device to connect it to, and the MAC is not listed on the box or the Apple TV itself.
(to answer the obvious, I am trying to pair it with an iPad, and I need to register the Apple TV for the network so the two can see each other)

As long as I know java doesn't have support to work on link-layer, only internet and transport layers. You may write simple native code. On windows, IP Helper functions, like SendARP allow you to pass an IP address and get the hardware address. You store the hardware address on your database/file and later, when that machine is off, you send a frame to the address you stored previous.

Can I get the IP address of my stolen iPad through find my iPad?

Hi. My iPad was very recently stolen when my house was burglarized. I have find my iPad turned on and marked the device as lost. Earlier, the iPad was located and the general location was sent to me. Unfortunately, the person who stole it turned it back off as soon as they saw that it was remotely locked (this is a huge problem to me, as a remotely locked device shouldn't be able to be so easily switched off). I told the police where it was located, but it wasn't on long enough to give me an exact location. So, they will not issue a warrant because it could be in one of about 4-5 houses.
Does anyone know of a way I can get the ip address that was used when the device reported it's location via find my iPad? If I have that, then we can get a warrant and get the police to look for it. It seems like this should be available, as the device was marked as lost under find my iPad. I just can't seem to find the info anywhere on the site.
If you have any advice, please help.

You don't need to know the remote IP if you have your PPP setup correctly. Check this site out.

No. Chances are excellent that there's a way to do what you want without needing the variable's address, however.

How to get the column index inside a dataTable

Hello,
before I get staked, there are multiple threads handling familiar topics to the one I'm questioning about but none gives an anwer. If there is one, I'm propably to less skilled to see it.
So here is my Problem: I've build a web-interface to a time-recording system. The hours worked on a certain project are displayed in a dataTable component which is generated out of a mySQL Query. Each entry (column/row) contains a inputText component to display and edit the specific value.
Editing one of these inputText elements now fires a valueChangeEvent which reads the new value and stores it in the database. For that cause I need to know the row- and column-index of the inputText component that fired the event.
Using the getClientId method from the valueChangeEvent I get some Information which makes it possible to calculate the row/column index. A typical clientID looks like "form_table:mainTable:0:_id14". "form_table" is the ID of the form the dataTable is in. "mainTable" is the id of the dataTable component. "0" is the row the component is in. And finally "_id14" stands for the id randomly given to the inputText component by JSF.
My Problem is now, that though I can calculate the column out of the[i] "_id14", this calculation is hardcoded. So everytime I add a component in before the dataTable, the calculation needs to be adjusted in the code.
The Questions:
- How to force a sensefull id indicating a column-index for the inputText components inside the columns of a dataTable?
- Nicer since no workaround: How to get the column-index inside the dataTable on a natural way? (e.g. out of the valueChangeEvent the specific inputText component fires)
After some investigation here on the board and on the net I know multiple ways to get the row index, (Things like component-binding and so on) but I can't find a answer on how to get the column-index.
Thanks to all answers and/or links to things my eyes missed while searching for one.

...then index 0 becomes index 1 and my program doesn't work properlyThe program works properly, just not as you expect it to.
As you've noticed the table gives you the flexibility to move columns around. So if you move column 0 to column 1, why would you expect to still use 0 as the index? The table manages the reordering of columns for you to make sure the data being displayed in each table column comes from the correct column in the data model.
You can manage this yourself using one of the following methods (I forget which one):
table.convertColumnIndexToModel(int viewColumnIndex)
table.convertColumnIndexToView(int modelColumnIndex)
Or, you can get data from the data model directly:
table.getModel().getValueAt(row, 0);

How to get the MAC address of the additional 10G NIC with ILO command line

how to get the MAC address of the additional 10G NIC with ILO command line?
thanks.

Hi Bruce,
Out from what I can find on this network card is it not possible to get the mac address without a OS. I would recommend you to get/burn a Linux/Ubuntu live CD/DVD and run a Ifconfig in there.
Hope it helps you.
