View 3 Replies View RelatedProgramming :: Physical Versus Virtual Mac Address And Mac Address From NIC's Firmware?
Apr 6, 2011I need a small shell based program that prints the mac address of physical ethernet adapter from it's firmware. I need this utility for license generation and appliance activation. I have tried several example but none of them is flawless, The easiest method I have found is to parse the output of "ifconfig" command but it has also some drawbacks.
1. Firstly program should differentiate between physical and virtual adapters. Physical means installed on board(wired or wireless) or installed additionally. Virtual adapters are those created by VPN or created by virtualization apps such as VirtualBox/VMWare etc. I am not interested in virtual ones.
2. In case of more them one physical adapters(wired and wireless), it should print the mac address and description(name & vendor) of both/all adapters.
3. If media is disconnected then also it should be able to read the mac address and description(name, vendor) of card.
4. This one is bit complex. I know that 'ethtool' can show you the universal mac address but it's limited to use only 2 types of drivers and won't work in all cases.

Dec 17, 2008When I try to access at physical address (0xD0000), we known that it is necessary to convert physical address to virtual address using function IOREMAP(0xD0000, 1024) and return me 0xC00D0000.
Now our doubt is when I have a board with I/O in address 0x150, is it necessary to convert this address to other virtual address??? or with inb(0x150) return me state of I/O in this address? How can I known where is this I/O address in my map memory?

Programming :: Extract URL From Firefox Address Bar ?
Nov 27, 2010I'm trying to create an application that monitors, among other things, what site the user is currently viewing. I would like to know if there is any way to get the current URL from the Firefox's address bar on a Linux machine. I know that under Windows I can use the DDE server approach, but under Linux this task is proving very tricky. I've considered an approach involving an extension to Firefox, but this would require the user to install the said extension himself. Which is not something I want. If an extension can be installed by a different program's installer than that could work, but I don't know if that's possible or not.

Mar 1, 2010I'm using at struct sockaddr_in to receive multicast data sent out from another machine. When I print out the source address using inet_ntoa it gives me the source address of the PC that sent the data. This is ok but I would like to know if there is a way of getting the multicast address that the data was 'sent to'. I know I can see the multicast address in tcpdump being directed to my PC but I would like to be able to display the multicast address too? Is this possible or does the sockaddr_in give me the source address of the packet not the multicast address that the packet was sent to?

View 9 Replies View RelatedProgramming :: Packing Sockaddr_storage With Either V4 Or V6 Address?
Mar 29, 2011Running into a weird issue when packing sockaddr_storage with either v4 or v6 address.
To demonstrate the problem, I created a sample test program(limiting it to v4 only addresses). The problem was observed on MAC OS 10.5.8 and Linux RHEL kernel 2.6.9-42 with gcc as the compiler.
* Function packAddrs() runs a for loop packing v4 addresses into a single structure. The input address is same for every iteration, output memory size is adjusted using realloc.
* After successfully packing an address, it prints the packed structure contents using displayPackedAddrs()
* The output is fine for first two iterations. However, at the 3rd iteration, the packed contents seem to have got corrupted. It prints only the first packed address. I have tried using (malloc and memcpy) instead of realloc but no improvement.
Included below is the code and execution output.
#include <stdio.h>
#include <stdlib.h>
#include <string.h>

Programming :: Implement A Dynamic Menu Which Will Allow To Specify An IP Address
Jul 2, 2010I'd like to implement a dynamic menu which will allow me to specify an IP address and read it into memory. This is what I've got so far (it's fairly basic...)
Code:
IPS=`ifconfig -a | grep 'inet addr:' | awk '{print $2}' | tr -d "addr:"`
PS3='Select an option and press Enter: '
select i in $IPS
do
case $i in
$i) echo $IPS;;
esac
done
echo $IPS
At the moment it just says "Which IP would you like to use" and then freezes, most success I've had is it showing all the IP's listed in ifconfig and then showing the same menu.

View 9 Replies View RelatedProgramming :: Shared Memory - Should They Show The Same Address?
Mar 17, 2010So I'll try to be brief and to the point here: I've got a couple of C / C++ apps that communicate with one another via shared memory. These worked completely fine until.. well, about twenty minutes ago when I finished making some network card changes and suddenly, I've got a weird problem going on. At one point, Parent app waits for Child app to set a boolean indicating it's finished initialization. This worked fine the last time I ran this app up (a few days ago). But right now, the shared flag never seems to get triggered (I've added a printf("Waiting..."); in Parent app until the flag is set). All the code leading up to it being set in Child app seem to be running smoothly, so I tried spitting out the addresses of the shared memory locations. The addresses mapped by Parent app and Child app are different; this seemed odd, so I went back and wrote a simple miniature app that just opened a shared structure on my own box, and I get the same thing - different addresses - but the miniature apps work just fine.
Is it normal for a shared memory space to be mapped to two different addresses across two processes?
If so, does anyone have any idea what might be the issue at hand with my Parent / Child app scenario? The Child creates the shared memory, the Parent has a wait before it opens it, and if it doesn't exist should fail (opening with PROT_READ | PROT_WRITE)... it doesn't fail so it's evidently there.
All of this worked until literally just a few hours ago and I made some changes to my network cards, and I can't even imagine how that could have changed whether or not shared memory mapping worked...
