We could even self-sign the respective file with an MD5 checksum (there's already an md5.c in kernelland), to prevent naive tempering. People too stupid to change an Ethernet address are also too stupid to UTSL. Solaris is foreable similarly. I once innocently reinstalled a Solaris x86 machine destined for a customer. I should have read the hostid FAQ before, this would have made me keeping the file in question on a floppy. The new installation created a new hostid, but i've already obtained a key for Firewall-1 for the previous hostid... After this, i've got a problem. :) Well, i read the hostid FAQ, and finally created a new hostid file similar to the one i've been using to obtain the license key. FreeBSD could easily create the hostid at installation time as well, maybe even by examining the first ethernet address (if any), this would even yield you the same ID again after reinstalling from scratch, as long as your hardware remained the same. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
