RE: knoppix question

Ended up downloading a few distro's/ toys. Does turn out hard drive is bad, rma time. As my last MS dos boot disk had gone bad (last made in Jan 99) I ended up using both lnx-bbc and Freedos. Trying to get away from Microsoft as much as possible, but those old single disc boot floppy are handy for all the dead but with warranty drives I have bought over the years.

Web Site
by Jonathan Hutchins 16 Dec '04

16 Dec '04

We've had several interesting projects discussed in the list lately. I wonder if we could add a section to the kclug.org web site where we can either post write-ups and HOWTOs, or post links to personal project web pages? I'm talking about the projects that people have actually done, not the long speculative discourses about how somebody _coud_ do something like a hand-powered webserver.

You should be able to modify the float voltage by adding resistance to the circuit. I have yet to make my homemade UPS. What do you recommend for an enclosure? I think it's safe to assume that marine/ motorcycle batteries are to big to fit in the APC battery slot. I was thinking about using sheet metal cut and bent.

Meeting Date

I just realized that the meeting was not last night, but is next Tuesday, 12/21. Duh! So, I think I can make that meeting. I'll see about getting the Q1 reservation filled out to drop off that night. BTW, I noticed that this statement on the website needs updating: "Free parking after 6:00 on the street or in the lot off of Oak on the east side of the building." That's for the old library, which was on Oak. Peace, Jim

I am not contesting the usefulness for Knoppix, but they do state Linux demo and educational CD *before* rescue system. Any Linux distro can be used as a rescue system, so stating that as a goal is redundant. > > I suspect you've conflated the design goals of the disk with the > uses to which you put it.

I have not had a broken system since switching to Linux 7 years ago (or more). [That is not to say that I haven't trashed my system by doing stupid experiments, but I have not had a system break. In these times tomsrtbt was all I needed. Or a new install of an upgraded version. I have yet to lose a single character of data from a Linux system. I have trashed: programs, libraries , rpm databases, and gentoo configurations. None of which, I suspect, could be fixed neatly by any tool.] > > How suited KNOPPIX is depends on the specific task at hand: True. I was merely stating that *if I were to want to fix a broken system* I wouldn't want to wait for X to boot, for KDE to launch, etc. I am, I guess of the old school that way. If you need to fix something, do it from the CLI. It's faster and you most likely will have more control. But then I don't do much in the way of fixing broken/borked Windows. I find it saves me having to digest massive quantities of Mylanta. ;') IMHO, Brian Densmore

I would only add one thing to that idea. I would make the script the default mount command and pass thru the mount command to the real mount command unless it was one of the "encrypted devices". Ok two things, I would also add an option to require a password or passphrase rather than just a public/private key scheme. > > ... easy to _not_ forget.

I would think you would want to do this every so often, to ensure a bit more security. Especially since it's relatively easy now to build a really powerful mainframe cheaply, that can do nothing but crack private/public keys. Not to mention the fact that the encryption techniques we thought were so secure turn out to have problems too. When is there going to be another key signing event?

Yes, it is all relative, but based on the designed use/audience for Knoppix (aka, GUI desktop, Linux newbies, Windows users), it would be most desirable to boot using as much power and with as little interaction as possible. Hence I made my comment based on the intended use and audience for Knoppix. My wife who is rather PC-illiterate, wouldn't know how to respond for a request to mount a swap disk partition and would probably make her nervous and she'd probably get frustrated and give up trying to use it. So I stand by my original statement. Certainly there are risks in doing that, but as I said before Knoppix isn't the ideal distro for troubleshooting broken systems. There are much better choices for such tasks. Brian
