Re: [leaf-user] Project Admin
While the LEAF project goals may not include the word floppy, and even taking into account the LRP history, there are a lot of posts in the archives discussing the need/perceived requirement to keep the Bering (and Bering uClibc) minimal runnable configuration small enough to fit on a floppy (maybe a non-standard 1.6Mb, but still on a floppy). My question, Is a LEAF distribution required to fit on and boot from a 1.44Mb floppy? was more rhetorical in nature, intended to spur discussion to get the real requirements figured out.

Ken, No. See: Project Goals Maintain as small a footprint as possible for release/branch target installations. Ken, Just to clarify, the LEAF project description and goals haven't had the word floppy in them for years. I'm guessing that would be an honoust mistaken from anyone that remembers the abandoned Linux Router Project. With LEAF having adopted so much from that earlier project it can be hard to tell the difference at first glance. The concept of having read-only media to boot from has, in my opinion, not lost its validity. The thought of being able to reboot and loose anything a hacker has changed, is very assuring. Obviously you'll still need to plug the leak that the hacker discovered, but at least you have no immediate worry about others discovering the hackers backdoor. I realize that none of the commercial products appear to be using this concept, but their solution is to reset to factory defaults. In essence that is no different, but it offers a lot less flexibility towards the people operating it. I do not use LEAF out of cheapness, I use it because I think I can do a better job than those commercial products.

I'd guess few people could even run LEAF from a single floppy at present time. I know I can't, and I've never owned any legacy system that could boot from non (IBM) standard disk sizes. Even in the old LRP days with the 2.2 kernel I was required to use a two-floppy setup at one point. As small as possible seems to me a much more valid target then trying to stay within 1.44Mb. That said, I do feel that efforts should be made to still allow booting from floppy in future developments. When considering power consumption it still makes a lot of sense to use a legacy system and many of those will simply not boot from CD or USB devices (but will allow using once booted).

Re: [leaf-user] Floppies WP
Look, there are obviously different perspectives on this. And that's to say that LEAF meets different needs! How much of an issue is having write protection? I can understand that it is better in theory but I can't think of a commercial firewall product (Cisco PIX, Linksys, DLink etc) that does not use flash and that has any sort of write protection. Why do you think we prefer LEAF to commercial boxes? Besides the obvious fact that one is FREE and the other not only costs money, but represents a monoculture that protects attractive targets, that is. Break one, get into all. If having boot from R/O media is an issue you could boot from CD and save to a floppy. You could also write protect CF media with a hardware hack to the cable. OH, now there's an attractive installation! So from my perspective this would seem to be a non issue for most users and that for those few where it is an issue there are ways around it with some extra work. As long as they have YOUR perspective, eh? For the record, I'm still using Bering-1.2, IIRC. It ain't broke, I've seen no reason to FIX it. I certainly WOULD be running from a WP floppy, except the BIOS of the Compaq pizza-box it's on won't boot from an extended format floppy, so I had to get cute tricky!

Re: [leaf-user] Floppies WP
I'm using two leaf boxes (3.1beta2 or beta1, I'd have to look again) that boot from CDROM and load from an older USB stick that has a hardware write protect switch on the drive. I have to power down and then move the switch to update or change settings but for the most part I haven't had to do that on a regular basis. I've also been using leaf since the 1.2 release and am very satisfied with it. Thanks!

Re: [leaf-user] Write Protect
Howdy, This is pretty interesting. I thought no one was making them with write protect anymore. I have been using a USB to SD card adapter and SD cards, because the SD cards usually have a write protect switch. Now, I wonder if any of these write protectable USB drives use good NAND memory. Most of them these days are MLC(junk), instead of SLC. None of the drives in this list said anything in their specs about the type of flash chips they are using. Do you know any that use SLC(Single Level Cell) and have a write protect switch? If they were close to reasonably priced, I'd have to go buy a few.

Re: [leaf-user] Write Protect
My USB sticks (I have three.) that I use for my routers are two Imation 32 MB and one Memorex 128 MB drive. I purchased them a few years ago and decided to use them in my leaf boxes when I upgraded USB drives for personal and work use and my leaf boxes. I think that one may be able to find the Imation drives floating around somewhere but the Memorex one I picked up at Target for a song since they were closing them out.

Write protected hardware requires physical access to the LEAF box. A
software write protect has the advantage that you can set and unset the
read and write access to the boot media with putty, ssh. I use two
scripts loaded by local.lrp. Granted this is a little cumbersome because
you have to keep a copy of three modules on your desktop machine and
scp / winscp them over as needed. If you command a reboot, the machine
is restored to read write status since the scripts are only run manually
via ssh.
