Jenny You might like to check out Freesco - a router/firewall/dns server/etc linux distro on a single floppy disk. There are others which are similar but Freesco seems to be one of the most complete and simplest to set up. It has spawned an entire sub-culture of add-on program with people using the distro for many other tasks such as mp3 server, web server etc. Once installed it can be administered via ssh to get to the command line or a web browser to the control panel. I have it on a massively over-powered machine - a 50mhz 486 with 16 megs of ram and a hard-drive and it works very well although AFAIK it can be used with a 386, 8 megs ram and no harddrive. If you are interested in trying it out I have another old 486 in the shed - may need some memory though. Regards Syd

Have a look at the manufacturers' websites for info on the drives and possible utilities to set the bus speed. I had some fun with a couple of different UDMA100 drives last year. The first one I bought would not work on DMA33 (even with the 80 pin cable - that is another thing to get right but you probably know that although I mention it just in case). Exchanged it for a different make which worked fine. Digging around on manufacturers' web sites revealed the reason for this odd behaviour. The drive may be set to UDMA100 by default - in which case it is unlikely to work out of the box on DMA33. A DOS utility is used to configure it. Alternatively, a drive may be set to DMA33 at source and possibly not be running at optimum speed when used on a UDMA100 bus unless configured. HTH Syd

Try a DOS boot floppy. I think there should be some 'free' DOS's out there. ( DR-DOS?) Or borrow a 'doze machine and make one.

Backup Strategies
by Keith Watson 15 Jul '02

15 Jul '02

When making significant changes to an existing system (e.g. kernel builds or major software changes), what backup* strategies do you adopt to protect yourself from knackering the whole thing? I know this will depend a lot on what hardware is available but is there a commonly accepted approach? At the moment I've got enough space on another HD to completely duplicate the whole partition (apart from a small /boot partition the whole of my system is in a single partition). I've been using PartitionMagic to do this but, as it's a Windows app, I'd like to use a GNU/Linux approach. Any ideas? * 1st time round I typed this as 'buckup', it occurred to me that all I needed to do was change the first consonant and it would be a better reflection of the entire process. Reminds me of way back when I was submitting batch COBOL compile jobs, the job output listings used to come back headed "System Complication Output". :o) Regards, Keith ____________ 'I can see nobody on the road.' said Alice.

As someone thats worked with these products I believe it's more than me saying thats how it was for me. These things are all setup the same so if I wasn't restricted from running setup.exe from cd then it wasn't restricted however I will conceed that the original statement is partially correct the RM windowbox systems which is their peer to peer network for primary schools does stop you running certain things like poledit.exe without phoning RM with a key to which they will give you a password.

UDMA 100, etc.
by Ricardo Campos 15 Jul '02

15 Jul '02

After my dodgy HD, I'm thinking of buying a new HD. My motherboard can only handle ata33, but I'm thinking if I invest in a new HD, I might as well get an ATA100 one and use it at the lower speed- I'll probably buy a new motherboard (&new CPU, etc) that can in a year or so anyway. Am I right in thinking that ATA100 hd's will work on a ata33 board? Ricardo -- Get your free email from www.linuxmail.org Powered by Outblaze

kernel panic! Oh poo.
by Ricardo Campos 15 Jul '02

15 Jul '02

Today, as I booted my box, it said that the kernel was using the wrong compression format and halted. So I rebooted, and the dmesg came up with lots of: hda: dma_intr: status=0x51 { DriveReady SeekComplete Error } Right at the end, we have: VFS: Disk change detected on device ide1(22,0) It booted, but some files just weren't there anymore. i.e. it had mount, but not umount. So I thought, bugger that, saved the dmesg, and rebooted. I was greeted with:- Kernel Panic! VFS: Unable to mount root fs on 03:01 It suggested to run e2fsck, so I did using a tomsrtbt rescue floppy. Fine. It 'fixed' a LOT on hda1. Reboot, Kernel Panic! no init found... SoI'm figuring that it's pretty much destroyed the data on hda1. Or, as I like to mount it, / Bugger. So I guess it's reinstall time for me, that way, I guess, I could possibly save /home . Or do people think it may be a hardware problem? Oh poo.

> have a box acting as an interface running nothing at all except internet > connection stuff, so that everything on the internal network is hidden > behind it. you might want to try apt-get install firestarter, if you're running woody (might be in potato). It's possibly the easiest firewall s/w you cound ever use (i.e. takes about 30 seconds). Of course, a custom hand-written script is best, but to get a home connection going I'd highly recommend it. You'll need a 2.4.x kernel, though, as it uses iptables. Of course, it's a bit overkill on dial-up! I tend to leave mine connected from friday 6pm to monday 8am (as it's free), so I use it 'just in case'. Also it means my laptop (which has no modem) can have net access. -- Get your free email from www.linuxmail.org Powered by Outblaze

I also have a spare kidney >(slightly damaged). ;) Sure, how much? Would you swap for a sack of soya beans? I've been reading about linux security, and apparently the best way is to have a box acting as an interface running nothing at all except internet connection stuff, so that everything on the internal network is hidden behind it. I had dreams of turning my current cobbled-together old box at home into the firewall beast, and buying a big fast shiny new computer and running a distro on it that I can start looking at desktop stuff on - I've only ever piddled around with command line so far really apart from mozilla. Then when our primary school decides to try linux I can sweep round and show the kids redhat running word editors or whatever :-) Anyone want to buy a broken motorbike? Buyer collects (from France).
