Actually, this is not quite exact. It is true that more cryptoanalyis was done on Serpent (which algorythm is easier to analyse). But so far more rounds have been broken in AES (Rinjdael) than in Serpent (unless I missed one of the lastest articles about thos algorythms, which is possible). The reason why Rinjdael was choosen as the AES instead of Serpent is unclear and even highly suspicious to me... It is admitedly a little faster than Serpent, but was pointed out as less secure than Serpent too (and as it was not as much crypto-analyzed as Serpent, one may find a shortcut attack on day or another...). My thought is that the NSA is probably quite interested in having an AES algorythm which is not too difficult to break... I personally use Serpent with 256 bits keys for the encrypted partitions on my PCs. It's of course probably too slow for the Q60 though (128 bits keys seem more reasonable for a poor 68060 @ 66MHz to deal with...). > > > What is the advantage of SuperMount over autofs? > > > > It's 100% automatic, doesn't need for any demon, and it doesn't hog the > > processor/drives by checking every few seconds that a new medium was > > inserted...

It's just like if you were using the medium under DOS/Windoze (Yuck !), or SMSQ/E... It's 100% kernel based and done at the driver level... The problem is that its author doesn't maintain it anymore and all the maintnance is now done by the Mandrake developers, and scattered in numerous patches to each kernel... There are times were you just can't find a proper (set of) patch(es) applying cleanly to a given kernel... Well, I could make one out of Mandrake's patches for Linux-vanilla v2.4.21 and I use it since v2.4.21 is out without a single problem. I'll put the patch on my q60linux website. ;-) > How do you configure it? It's like a filesystem driver. You configure it in fstab, example: /mnt/dos/a /mnt/dos/a supermount fs=vfat,dev=/dev/fd0 0 0 /mnt/cdrom /mnt/cdrom supermount fs=iso9660,dev=/dev/cdrom 0 0 More option can be passed to the underlying driver.

I patched the sources and I'm trying to compile them as I write this message...

There are no SRPMS in it though... Or do I look in the wrong place ? Thierry ([EMAIL PROTECTED]).
