Date: Fri, 16 May 1997 11:12:31 +0200 Organization: Eindhoven University of Technology Message-ID: <337C24FF.167E@inferno.phys.tue.nl> NNTP-Posting-Host: inferno.phys.tue.nl Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit X-Mailer: Mozilla 3.01Gold (X11; I; OSF1 V3.2 alpha) Lines: 53 Xref: euryale.cc.adfa.oz.au comp.unix.bsd.freebsd.misc:41015 I would like to obtain the physical address of the network-adapter. Does anyone have some code to do this? I had some code for the DEC-Alpha but that did not work and I could not manage to patch it since I do not know enough about FreeBSD 2.2.1 to do this. Can some one please help? Whishes, Gert P.S. The code for the DEC Alpha looks like this. #include <stdio.h> /* standard I/O */ #include <errno.h> /* error numbers */ #include <sys/socket.h> /* socket definitions */ #include <sys/ioctl.h> /* ioctls */ #include <net/if.h> /* generic interface structures */ main() { int s,i; static struct ifdevea devea; /* Get a socket */ s = socket(AF_INET,SOCK_DGRAM,0); if (s < 0) { perror("socket"); exit(1); } strcpy(devea.ifr_name,"ln0"); if (ioctl(s,SIOCRPHYSADDR,&devea) < 0) { perror(&devea.ifr_name[0]); exit(1); } printf(Address is "); for (i = 0, i < 6, i++) printf("%X ", devea.default_pa[1] & 0xff); printf("0); close(s); } -- ------------------------------------------------------------------------------- G.A.J. van der Plas | e-mail:gert@inferno.phys.tue.nl Eindhoven University of Technology | http://tnj.phys.tue.nl/users/gert ------------------------------------------------------------------------------- 'The ultimate good is not to be afraid.'
