This is a relatively simple question, but being new to DEC equipment I am
having trouble finding the answer. Is there a unique hardware ID for a
DECstation 3100 ? How do I access it?
Please note that unique = non-software setable and that can be used to
distinguish one 3100 from another. Thanks in advance. Please email replies
to: bmc@bru.mayo.edu if the above address bounces.

But, if you really, REALLY want something close, you can use the Ethernet hardware address. I've been led to believe that if you have a socket and use the right ioctl(2)'s you can get the hardware address. The address chip is socketed so it can be moved to a different CPU board if there is need to. > > --Bruce > ---------------------------------------------------- > Bruce M.

Here is a program that prints out my ethernet address on my DECstation 3100 running ULTRIX 3.1:
#include <stdio.h>
#include <sys/types.h>
#include <sys/socket.h>
#include <sys/ioctl.h>
#include <errno.h>
#include <net/if.h>
extern int errno;
main(ac, av)
int ac;
char *av [];
{
int s;
char *line = "------------------------------------";
char device [IFNAMSIZ+1];
/* structure used to query de and qe for physical addresses
struct ifdevea {
char ifr_name[IFNAMSIZ];
char default_pa[6];
char current_pa[6];
};
*/
struct ifdevea hw_addr;
s = socket (AF_INET, SOCK_DGRAM, 0);
if (s < 0) {
perror ("socket:");
exit (3);
}
if (ac > 1 && strlen (av [1]) <= IFNAMSIZ)
strcpy (&hw_addr.ifr_name [0], av [1]);
else strcpy (&hw_addr.ifr_name [0], "se0");
if (ioctl(s, SIOCRPHYSADDR, (caddr_t) &hw_addr) < 0) {
perror ("ioctl: SIOCRPHYSADDR");
close(s);
exit (1);
}
printf ("\n%s\n", line);
printf ("addresses for %s :\n", &hw_addr.ifr_name [0]);
printf ("%s\n", line);
print_addr ("hardware-address", &hw_addr.default_pa [0]);
print_addr ("current-address ", &hw_addr.current_pa [0]);
printf ("%s\n", line);
close(s);
}
print_addr (what, ether_addr)
char *what, *ether_addr;
{
printf ("%s = %02x-%02x-%02x-%02x-%02x-%02x\n", what,
ether_addr [0] & 0xff,
ether_addr [1] & 0xff,
ether_addr [2] & 0xff,
ether_addr [3] & 0xff,
ether_addr [4] & 0xff,
ether_addr [5] & 0xff);
}

I would like to thank all who helped me out with my 3100 hardware ID problem.
I received many thoughtful and helpful suggestions, code and code fragments.
The general opinion was that I should use the ethernet address for the machine
as the ID.
