You can make _two_ hashes and then concatenate to form unique key. Then you still be able to see "a lot of single IPs". Personaly, I dont care very much about IP/hostname disclosure :-)
I still like my idea the best for unique keys. It's a better way to detect hosts behind NATs, here it is again, four versions to pick from: # ifconfig | sha256 cbcc2f55a340c248af7e8a10871150d827af11d7051bbc782eefa04b0603248b # ifconfig | sha1 b607b9d45e6ad40c02ab20800e0d70245ab6db68 # ifconfig | md5 22a2a3eca61166fb113f1a688b3dd842 # ifconfig | cksum 3977021799 540 The only down side is it still can be faked, just like everything else. -- BSD Podcasts @: http://bsdtalk.blogspot.com/ http://freebsdforall.blogspot.com/ _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
