Hi,

I recently tested a new way of checking checksums of different mirrors, I 
call to an ISP in France (from Germany) in order to pull the MD5 and 
checksum files from a list of mirrors.  I then cross-check these with my 
ISP's openbsd mirror.  The process I can automate a little better but it 
seems to work.  

data:

-rw-r--r--  1 root  wheel  3775 Jan  9 12:10 129.128.5.191.cksums
-rw-r--r--  1 root  wheel  3775 Jan  9 12:10 130.237.237.229.cksums
-rw-r--r--  1 root  wheel  3777 Jan  9 12:10 131.188.40.91.cksums
-rw-r--r--  1 root  wheel  3777 Jan  9 12:10 192.43.244.161.cksums
-rw-r--r--  1 root  wheel  3648 Jan  9 12:10 200.32.4.56.cksums
-rw-r--r--  1 root  wheel  3648 Jan  9 12:10 203.16.234.85.cksums
-rw-r--r--  1 root  wheel  3648 Jan  9 12:10 203.16.234.86.cksums
-rw-r--r--  1 root  wheel  3648 Jan  9 12:10 203.8.116.111.cksums
-rw-r--r--  1 root  wheel  3777 Jan  9 12:10 204.152.184.203.cksums
-rw-r--r--  1 root  wheel  3777 Jan  9 12:10 209.242.32.10.cksums
-rw-r--r--  1 root  wheel  3648 Jan  9 12:10 62.116.6.182.cksums
-rw-r--r--  1 root  wheel  3778 Jan  9 11:54 ftp.freenet.de.cksums

At that point (if you look at the timestamp) it's been 4 hours since the 
OpenBSD main source did a change in the kernel versions and all the other 
mirrors hadn't picked up the changes.  So there was a checksum mismatch.  I 
was wondering whether a history file of checksums is a good thing to include on 
the main ftp site?  That way one can check whether older revisions of 
binaries are the right checksum?  Otherwise one would not know (and there 
would be no point of checksums then right?).  

Perhaps there is a better way to check checksums in a more secure way than 
FTP?  What way would this be, at best?  My calls to France hope to at least
find some out of band channel to cross-check binary checksums, but it's not
economical until I update my long-distance phone plan (I'm just testing the 
water right now).

Regards,
