FreeBSD has o{g,s}ethostid under COMPAT_43 and kern.hostid. Note that the 4.4BSD, Lite1, Lite2 and final include code to extract the hostid out of a SPARC ID prom. I don't know if this is still relevant to UltraSPARC machines. --=20 Peter Jeremy --IU5/I01NYhRvwH70 Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (FreeBSD) iD8DBQFGGAsW/opHv/APuIcRArJUAJ9uLvuTFQEd/j+kHhfCxYeqLCvPGACcCWAh wKHbwxSaCn+YKC8iX+IeDk0= =z1tz -----END PGP SIGNATURE----- --IU5/I01NYhRvwH70--
