How do I find “Ehthernet Physical Address”.

The easiest way might be to run your driver with the -v option.
This will display the MAC address on the screen.

If you have the Net driver running, just type “netinfo -l”. It will be
called Physical Node Id, in the list of information presented.

and as addition to replies: you’r running tcpip then try “netstat -i”

How I can it into programm.
Is there way without netmap?

Try this:
#include <stdio.h>
#include <malloc.h>
#include <sys/kernel.h>
#include <sys/net_nq.h>
#include <sys/net41msg.h>
#include <sys/net_drvr.h>
#include <errno.h>
void main()
{
int ctr;
int pid;
struct _net_rnodemap rnodemap;
char data[1024];
struct _net_rnodemap_reply *rnodemap_reply;
int nids[20];
if ((pid=qnx_vc_name_attach(0, 64, “qnx/net”))==-1) {
printf (“Could not attach to Net (%d)\n”, errno);
exit(0);
}
memset(&rnodemap, 0, sizeof(rnodemap));
rnodemap.type=_NET_RNODEMAP;
rnodemap.log_nid=getnid();
rnodemap_reply=(struct _net_rnodemap_reply *) data;
if ((Send(pid, &rnodemap, rnodemap_reply, sizeof(rnodemap),
1000))==-1) {
printf (“Send error\n” );
exit(0);
}
printf (“MAC: “); // If you have multiple cards you will need a loop here
for (ctr=0; ctr<6; ctr++)
printf (”%02X”, rnodemap_reply->card[0].phys_addr[ctr]);
printf ("\n");
}

Oh ya, the following assumes this question (and thread) was referring
to QNX 4.xx

This method isn’t safe. If for some reason a wrong MAC address
was specified in the netmap file you will not get the right MAC
address.

Quite true. It does assume you have a properly configured system.
But the person seemed to be looking for an alternative to doing
a popen(netmap) and parsing the output. This does give the same
information the netmap command would have given.
Given that caveat, it is useful code.

Indeed, I never mean to say it was useless. I was just pointing
out one must understand what this realy does. It doesn’t
get the MAC address of a card, it get the MAC address in
the netmap database, quite different, trust me

That post wasn’t mean for you David,
I was meant for the other listener.
I know you know, and you should know that I know
