I had a slight false start, owing to some missing symlinks, but I soon fixed those, thanks to this list, and then it was ALMOST trivial - just type in the right commands in the right order and make plenty of tea between each command. Also, I discovered a mag called Linux Format (thanks to John Seago) and that has a cover CD bearing the source code for kernel 2.4.9, which is what I used for my new kernel last week. So I didn't even have to download 28Mb of source code before I started! I'd read somewhere that I should expect the compilation to take hours or days on an old PC (my P166 is ex-skip) but I was done in less than an hour, once I'd sorted my way through the 'make menuconfig' stage. So if I can, I'd say anyone can. If you want me to share my lack of knowledge any further, feel free to ask! I found the Kernel HOW-TO quite helpful and there's a README in with the source (which, had I read it more diligently, would have probably saved me falling into the lack-of-symlinks hole...). Hope this encourages you? Gerald.

thanks for pages_failed info
by Jenny_Hopkins＠toby-churchill.com 06 Nov '01

06 Nov '01

Ta to all for help with the alarming pages_failed messages. I now understand that 1. I shouldn't set a large cronjob to run every minute by mistake ;-) 2. Kernel 2.2.18 is not so hot on memory management and i need to do my first new kernel installation 3. I need to set sysrq in some boot script or other to avoid crashing out like i had to yesterday. Now I can spend the next month trying to find out *how* to do these things...whoohooo! Sorry if I caused any confusion cross-posting on two lists. Some interesting merge talks coming out of it though. Jenny.

Some people find the kernel-package package in Debian is > helpful, but I tend not to use it. I recommend make menuconfig... After last night, and making a kernel with the IPSec patches in by just typing the right (one) command, I've decided that make-kpkg is lovely. Now all I have to do is switch my firewall box over to Debian. And repair its disk. And ideally find it a monitor which hasn't got 20 second phosphor persistence... Incidentally, when I've used SysRq I've found it needed enabling with an echo 1 >/proc/sys/kernel/sysrq on boot. Do it. It's invaluable when your machine goes tits up. (Especially when it's a general workhorse machine that everyone uses, with 40G partitions and a strange intermittent kernel bug that makes it impossible to reboot.) -- Ian.

This box is *ancient* - it is 68000 based and incredibly solidly built. Unknown amount of memory hard disk (if any). Has not been plugged in for several years. Assorted tapes, cables, mice and other junk to go with the above. All free to anybody that can be bothered to come to Eastbridge (near Leiston in Suffolk) to collect it...

Debian, Slackware, hardware, BIOS and what am I doing wrong?
by John Seago 05 Nov '01

05 Nov '01

I have at last managed, with help, for which many thanks, to get my BIOS set up properly so that I could install Mandrake 8.1. However I am still unable to get Debian or Slackware in. I was told this afternoon that I may get some more suggestions if I post to this list again, so here is a reiteration of my position and the problem. I have two hard disks, one 10 gig as the primary master (with `Windows' on), the second 40 gig disk, (with partitions for Linux, and Mandrake 8.1 installed on /dev/hdc5 is the secondary master. The CD drive is set as the primary slave. I can get Debian to install as far as the base system, but on rebooting into it it can not access the CD drive. Slackware does not install as when one gets to the point where the system is installed it reports all sorts of stuff not installed from an earlier part of the installation. Am I trying to do something which is impossible, should I only be installing one set of linux, am I trying to do it in the wrong order? I could get rid of windows from the first disk, but I would prefer to keep it for the better quality printing it provides, (although I could be persuaded that the other benefits of Linux outweigh it). Suggestions and advice would be welcomed. John seago

Indeed, but there's nothing inherently "wrong" with it and the original query was how tricky is it to *upgrade*, not compile. Use make-kpkg if you want to tune things -- it's not that hard -- but in a hurry, the debian kernel-image packages are an easy upgrade. -- MJR

I'd say - very small mailing lists don't work so well because no-one has the information others need - medium sized mailing lists work well, because the information's available and people pay attention to conversations they're not actively participating in, so that the same questions aren't repeated over and over; and - in big mailing lists, there's too much noise to continually pay attention, which means that people with answers give up replying to questions and others don't spot the useful information in the flow of traffic, leading to the same things being asked over and over. Given Wells's theorem of mailing lists, I think that a CLUG+ALUG list should be about the right size to get useful discussions going and that (judging by the volume of technical traffic, as opposed to 'anyone coming out this Sunday') the CLUG list alone isn't quite big enough. -- Ian.

Depends whether a remount-read-only flushes out the 'file system clean' bit when it's done at this level, or whether the change waits for the next sync, which is presumably the concern. Aiui a normal remount/umount wouldn't return until the flush is complete, but this method is far from normal.

Well, sod you. These CLUG people seem to have an aversion to trimming quotes and their mailserver is still not accepting my subscription request, so maybe they deserve to be held. :^) Seriously, there are reasons why the ALUG lists are set up in the way they are. Bitter experience is one of them and I think the issues around them have been talked to death on-list, so the archives might make interesting searching. > When a friendly human admin has time to moderate, that's bearable. I don't > object to moderated lists, when there is a good reason to use that approach. This list is not moderated, but posts by unknown addresses and ones which match certain other common features of past spams are held for one of the (currently three) list admins to take a look at before they are allowed through. > I was told that the CLUG listserver maintainer is long gone, however.

This lovely message was waiting to greet me on all consoles of my debian box when i came in to work this morning, and I can't telnet in. A search on google says: >Upgrade to 2.2.19 , that should fix the problem. It's a bug in the >releases between 2.2.14 and 2.2.19, afaik. Has anyone heard of this before? I'm using kernel 2.2.18pre 21, activity on box over weekend should have been minimal apart from backups running. And what were those keys that try to reboot cleanly again? (not the ctl-alt-del) (Hope it isn't going to be one of "those" days....) Nice to meet so many folk yesterday. Jenny.

It's also not there by default in Redhats to 7.1 (not tried 7.2), although RH-default kernels have sysrq compiled in. Strange. Dunno whether there's a nice way of turning it on; we just bodged up an init script for it.

RedHat7.2 memory shortage?
by Glen Tyler 05 Nov '01

05 Nov '01

Hi everyone, I'm just starting migration, and was impressed enough with what I'd seen of an old copy of RedHat 6.0 to install RedHat 7.2 on my machine. Its a P133 with 64MB, and 4.0GB hard drive. While I'm impressed with all the eversocool features of this (desktop) install, it has slowed the system to a crawl. Everything seems to take ages to load and respond, and trying to do anything more than just move the mouse about or type in Kword seems to involve a huge amount of thrashing of the hard disc (the swap space being utilised?). I've noticed that balsa as and email client and Galeon as a web browser seem faster than Mozilla - is there a suite of 'lighter' programs that I should choose? Any recommendations? Glen
