Having fun with live Linux CDs

As one of the ways to keep track of my journey through the world of Linux and BSD distributions, on every CD I try to write the date I burned it. I can't remember how I found out about my first Linux live CD, Knoppix 5.1.1 (some Web story must've gone on about how great it was to run a full Linux without doing a hard-drive install), but the date I wrote on the case is Jan. 29, 2007 -- soon after the 5.1.1 release came out. And it wasn't just my first live CD, it was also the first Linux CD of any kind I made -- and my first experience with a Unix-like operating system since leaving adm3a and VT-100 terminals behind after my college days in the 1980s.

I remember running that Knoppix CD on my Dell box. I didn't know what Debian was. I had no idea that KDE was Knoppix's desktop environment -- or that there were many alternatives. I didn't know why the Web browser that looked like Firefox was called Iceweasel.

Since then I've spent considerable time running Puppy and Damn Small Linux from live CDs (and in hard-drive installs, usually of the three-or-so-file "frugal" variety).

I recently burned both Puppy Linux 3.0 and Damn Small Linux 4.0. On the one hand, I'm thinking about doing reviews of both. On the other, I think it's time to replace the Debian setup on the $15 Laptop, a Compaq Armada 7770dmt. I've been running it for months with a very basic Debian Etch install. I started with the "standard" install, then added X and Fluxbox, along with the apps I wanted. It's been running fairly well, but the problems with various applications have been piling up. I know that if I use Puppy or DSL, the apps I want should work perfectly from the get-go. Of course I could also do a fuller Debian install -- say the Xfce version -- which would include many more applications ...

So before I dive back into live CDs, here's what's been troubling me with my Debian Etch install. The laptop is so old (probably circa '98) that it doesn't have USB ports. I have my trusty Orinoco WaveLAN Silver PCMCIA wireless card installed -- it works with just about every Linux distro out there -- and I have the CD drive plugged in. The floppy drive is dead, but who needs it? I have the original 3 GB hard drive, and it's pretty full, even though I've got nowhere near the full Debian install on it. I really should buy a new hard drive that's way bigger and less prone to failure.

Anyhow, the 233 MHz, 64 MB system probably could run Xfce, but I've been conservative, running both the console and Fluxbox as needed. Maximum memory for the Compaq is 144 MB, but I've been too lazy and cheap to buy the RAM. The CMOS battery is dead, and I've really been too lazy to crack the case (TORX screws aplenty) and see how to switch it out. I have the network time server app installed, and that resets the clock at each boot.

I originally wanted to handle my work e-mail over IMAP with Mutt and MSMTP. Never mind that to get a Mutt setup seems to be the height of geek competence (a height to which I do not reach), but since my original push to get the .muttrc and .msmtprc files just right, something changed and I can no longer send mail. I could never figure out how to handle multiple mail accounts over IMAP (POP is easier, since you can POP all the mail down and filter it ... and by "easier," I mean harder but doable).

So I installed Sylpheed, which I figured would be light enough for the 233 MHz box. I've always liked Sylpheed, although I've migrated over to Evolution and Thunderbird on my other boxes.

On first launch of Sylpheed, I got an error message that some parameter in some file (I confess, I didn't recognize any of it) was missing. So I went ahead and configured Sylpheed. It didn't work.

I have AbiWord installed -- my go-to lightweight word processor -- but the graphics of the laptop just can't keep up. I type, and the letters appear seconds later. Ted might work better, but it's broken in Etch. You can neither create a new file nor open an old one.

On the brighter side, the Dillo browser works great (although the fonts are better in Damn Small Linux and Vector), and I also have had no problem with Iceweasel (aka Firefox), Lynx or my favorite light image editor, MtPaint (which should be an official Debian package available via apt-get but for some reason can only be found at Sourceforge and on other distros like Vector and Zenwalk). I've also been very pleased with Mousepad as a text editor, with Nano and Vi as backups. (I'm more of a Nano users because I just don't spend a lot of time in console editors and have ragged Vi chops).

So I'm able to get my work done in Etch, but I have a feeling that I'd be better off -- especially at 64 MB of RAM -- with Damn Small Linux.

And with the release of version 4.0, what better time to re-evaluate the distro, which has been in or near the Distrowatch top 10 for quite some time.

So I pulled the CDs for Puppy 3.00, DSL 4.0 and Knoppix 5.1.1. I'm not ready to break out the Compaq laptop just yet, so I used my main test box, the converted Maxspeed Maxterm thin client that runs a VIA C3 Samuel 1 GHz processor and 256 MB of RAM.

I plugged in a USB drive, with my hope being that I could then unplug the hard drive, boot from CD and then have no drives whirring for the duration.

That worked with Knoppix, Puppy, even with a Vector SOHO live CD I burned a week ago (and let me say that just as Vector excels with the Xfce desktop, it also does remarkably well in KDE).

But Damn Small Linux? No, it wouldn't boot with the hard drive disconnected. I tried versions 3.3 and 3.2 as well. No go for any of them.

My USB key is a little unsual. It was a freebie, and has a CD advertising image (detected almost always as drive sr0) as well as a 256 MB flash memory. Puppy found the flash just fine (I've always had great luck with hardware detection, especially of drives, with Puppy), and I was able to boot without a hard drive, run entirely in RAM, and save my settings and files to the pup_save on the USB drive. Brilliant, as usual.

Neither Knoppix nor DSL could find the USB flash drive, but I suspect with a "pure" USB drive the results would be different.

Even so, I've done quite a few Puppy reviews, and I wanted to start out with Damn Small Linux. So I plugged in a hard drive, booted DSL (using the dsl toram boot code that loads the whole distro into RAM) and was off.

Quickly, things that are better in DSL 4.0: network configuration is smoother than ever. Once I entered my static IP, DSL guessed the rest of the info pretty darn well. I entered my local name servers, but the gateway and broadcast addresses were correct without me doing anything. I was able to get printing working with apsfilter (I could never replicate my success in Etch, by the way).

The default window manager in DSL is now JWM, and the thing I miss most is the menu that used to come up with a right mouse click. It's easy enough, however, to change window managers to the old DSL's Fluxbox, and then everything is the way I like it. But I'm getting used to JWM (Joe's Window Manager) in DSL, and I like the clickable folders on the desktop -- it's easier and more intuitive than using the file manager.

Anyhow ... I'm not ready yet for a full DSL review, so let me just tell you that to me -- and many others, I suspect -- Puppy, DSL and Knoppix are VERY important distros in the Linux universe. Going from Windows or Mac to the world of Linux might not have happened for many of us if we didn't have live CDs that actually work that way with which to experiment.

And in many cases, working with a live CD or frugal install that allows files and parameters to be saved, either on the hard drive or on removable media, can be an easy, secure and preferable way to use a PC. Especially when it comes to DSL and Puppy, upgrading can be as easy as downloading and burning the latest ISO. And if you don't want to upgrade? No problem -- just use the version you want.

I did spend at least half a day running Knoppix with no hard drive. As I said above, Knoppix didn't find my USB drive (a situation that might be remedied with a more standard flash drive). As the king of live CDs, Knoppix, which is not one of those distros that is continually coming out with new releases, runs very, very well. Even when not running it in RAM, Knoppix is surprisingly quick, even with KDE. And if you do have 1 GB of RAM, I highly recommend running it with the toram boot option. I definitely plan to get the book "Knoppix Hacks," which has a new release slated for this month, as well as the new Damn Small Linux book.

And this thought has crossed my mind: I just might hack together a PC with 2 GB of RAM, and either a Compact Flash card or USB flash drive for storage, with no hard drive at all, to run Knoppix entirely in RAM.

(By the way, Puppy seems to know when it has enough memory to run in RAM -- I don't think you have to pass that information in a boot code).

And while the live CDs of Ubuntu, Mepis and others are helpful in terms of evaluating hardware detection, they're not designed to be used day-to-day in that manner. But DSL, Puppy and Knopix are -- and they all can be installed to the hard drive if you wish.

Before I wrap up this entry, I want to say that everybody should try Puppy, DSL and Knoppix. Download the ISOs, burn the CDs and start experimenting with all the boxes you can find. I've had more fun with live CDs than in anything else I've done with Linux. After a few months in Debian, Slackware and Ubuntu, it's a nice change of pace (and yes, I've tried Slax -- which I like -- and I plan to give Wolvix a spin soon).

So burn yourself some live CDs -- and make a half-dozen or so extras to hand out at will. It's the best way to get people started on exploring the non-Windows world of computing.
