I am not sure how to get your system back to how it should be, but for future reference if you want to disable root login, instead of following a RedHat Guide just Open Mandrake Control CentreSecurityLevels and Checks Selecting High (or is it Higher) security level will disable root login. Or alternatively regardless of your security level you can customise your existing level by selecting the 'System options' tab. The 'Direct Root Login' option will enable/disable root login for you. Hope you manage to recover the system without a reinstall. You might be able to set a new root password if you go into run level 1. Try booting into 'failsafe' from your lilo menu. derek Hi Derek, Cheers for the quick response. No I'm buggered... Run level 1/failsafe gives all the same problems. The root account is disabled because it can not be accessed/logged into from any tty device. Can I mount the physical hard disk on a different Linux box and change the securetty file? How would I do this? Would it just show up in the mounts if I plug it into an IDE port or do I need to do else to mount it (e.g. alter fstab on the other machine)? I.e. hate Slackware because its harder to find the relevant configuration files for stuff... Its all a bit bizare because the machine is stable as an internet gateway its not urgent (it still works without root access).

You then need to turn on ACPI (MCC - boot options). If you don't turn it on explicitly it won't be there! As I found to my cost trying to get my modem and soundcard to work (needless to say they did when ACPI was turned on). You can then throttle the CPU to all the states it supports, check the battery state (current and previous maximum recharge). Its all buried in the /proc/acpi/ directory which interfaces to the kernel. I tried running my 2.0Ghz P4 at 512Mhz which was quite a laugh :-) My BIOS only allows 1.0Ghz, 1.5Ghz or 2.0Ghz so I thought that was quite cool. I could also see the CPU temperature (found that my fan comes on at 54C and goes off at 46 with hysterious). To throttle you can just type: echo number throttle Or something like that (I am sure you get idea). Its wee while since I played around with it. The KDE version I am/was using didn't support automatic shutdown with low battery charge but the /proc/acpi interface was very accurate (I found) so thats not such a big problem. -- Best regards, Robertmailto:[EMAIL PROTECTED] Want to buy your Pack or Services from MandrakeSoft?

So a P3 running clock for clock is always faster than the P4M because the P4M has a deeper pipeline (cache misses hurt more). It is crazy that a clean architecture like that used in the PowerPC ISA isn't the dominant CPU type on the planet. Just like how Linux plays second fiddle to MS (because of 3rd party support problems). The P4M doesn't have the SSE extensions implemented in hardware. I compile my Linux kernels with the P3 switch for my Laptop (the closest match just now I understand). Also laptops use slow 5400RPM harddisks...

One of the old 486 has a port replicator that enables me to set up network connection. So having it networked with our new computers all it should have to do is display what I need. Step daughter use the other 486 laptop, as a simple text editor. She likes to sit outside on nice days and work on her home work. Mostly just taking notes wile reading books. Saves it to disk then uses new computer to format text, email it, and or print. I have a Pentium 1 100 MHz desk top I want to use for firewall, router. Install two NIC cards eth0 would connect to DSL modem. Then eth0 bridged to eth1 connected to a hub that provides wired and wireless networking for all of our other computers. I am thinking that after installing Linux and setting up network on this computer it would not need a monitor. As it would be administered remotely by another computer on the network. This hub that I was looking at in one of our local stores, shows the DSL modem connected to it. This hub then provides wired and wireless connection to other computers. With this arrangement I would not need the Pentium 1 100 MHz desk top. But then I believe that this would not provide the security I want. Hi Ray, I couldn't help but butt in and comment that an old pentium-based PC with Slackware, or Mandrake (minus X), or perhaps IP Cop (??) will allow you to have all the security you want/could need. In my experience of hardware routers (Vigor 2600We and IX66) the stateful firewalls, even on an IX66 which is VERY capable, always lack the configuration options I need! I could never get the IX66 to be transparent to my file sharing software, whereas with IPTABLES in Linux I can. This stuff is fast as it is actually built into the kernel and easy to configure as you can set up the filters, etc. from the command line/bash scripts. You can't do as much QOS stuff which is really useful. I can configure my Linux-based DHCP server much more than I could a hardware router (e.g. assign Wins/netbios information for Winblows). Where Linux falls over is drivers for wireless cards - that is a bit of a nightmare (of course some are supported). Why do manufacturers write network hardware drivers for Windblows and not Linux? Try to get Windows to act as server is like trying wade through treacle... :-) I had great fun getting a conexant PCI ADSL modem driver to work with Linux. Its handy though because it means I can do NAT on the Linux box and not have to worry about an external modem doing something stupid (or not being able to find the modem web configuration page)... You can easily configure the Linux box using SSH. Who needs fancy web config pages :-) If you do you could always use IP Cop... Don't bother with hardware routers, a Linux box and cheap hardware SWITCH (netgear are really nice) is a more powerfull combo and its more efficient... -- Best regards, Robertmailto:[EMAIL PROTECTED] Want to buy your Pack or Services from MandrakeSoft?

Though I noticed one of my daughters has recently started using xcdroast a lot , say's it works great. Oh well, great things from small beginnings, do proceed. You know it's a confidence thing ! But I digress. Yesterday I reseated the heatsink for the 'n'th time. This time I deliberately bent the retaining clip so as to exert more retention thrust onto the cpu, in otherwords the it took more of a push to retain the clip to the cpu. Current results are:- FSB100 == startup/desktop Full CPU load cpu 34C/41C 49C Case25C/30C 35C fan 3624 3668 Vc1.74 1.74 Vh1.25 1.24 Vp3.315 3.37 4.85 4.84 12.3 12.3 -12.40-12.40 -5.07 -5.07 These are not bad temperatures to my mind.

I presume it is 2.4.x series :-) Is it stock or custom? You might try a custom kernel with ACPI statically linked and APM left out completely (APM can potentially clash - although I think this problem is fixed now in the 2.4.x kernel). Does dmesg have anything useful in it? Maybe you could post it here? Whats lurking in your /proc/ directories (interrupts, pci, etc.)?

I currently have an all ally evercool ND15-715CA it has a 70mm fan controlled by bios. I think the airflow seems good. No reason to think it is getting trapped. The only thing about this heatsink that has me questioning it is the power of the retention spring clip itself. Compared to other makes and models I've fitted before, the retention clips are too easy to fit to the cpu. No, I hear you say, so what. Well the heatsink , if you notice carefully, sits in situe on 4 small rubber grommits about 3mm each in diameter.So the heatsink has to be held really firmly against them to make the heatsink BED down flush onto the cpu. If insufficient pressure is exerted by the retention clip there might be a possibility of the heatsink not fitting flush onto the cpu. I know, the heatsink paste ought to take care of it but maybe not enough ? It's only a thought. I already have both the case sides off , don't make much difference though, about -1C is all I get overall on the case temperature. Case airflow is in at the front low down under the harddrives and out either through the PSU, or a vent in the rear of the case undet the PSU. Entirely conventional in layout. I have no means of removing the top. I don't know what else I can do without getting surgical . The computer sits on my bench beside me which means about as good a spot as I will get for general room airflow. So what I'm reading from your experience seems to suggest I ought to be getting better general temperatures than I am getting, but with the one possiblity of the strength of the retention clips , I cannot see what I'm doing differently from you and yet I would feel more comfortable if my cpu temps were held well withing the 40 to 48 range under all load conditions.

You could always use a 6cm-8cm adapter+ 8cm fan to increase the airflow over your heatsink. For an Athlon 1800+ which isn't overclocked you shouldn't really need a new heatsink. However AMD are taking out of their backside if they think that a patch is the way to bond a heatsink to a CPU!! Always use high grade heatsink compound (I always use Artic Silver - but thats just laziness :-). If you do want to spend lots of money Swiftech make very nice copper heatsinks :-) This is unlikely to be the root cause of your problem. Athlon CPUs do run hot. So do P4's for that matter :-) My laptop (P4-M) has a cooling hystersis which switches in at 54C and off at 46C. I built up a Athlon 2500+ based PC for a friend. Even when its not overclocked and with a huge Coolermaster blower-type fan it still runs at 47C idle!! Have you thought of a powersupply issue? The PSU will be under strain when your CPU is drawing a lot of current (mainly to heat your house). The PSU in another PC I built even tripped the MAIN circuit breaker in the flat :-) The powersupply became more and more unstable (PC just died occasionally). That powersupply was rated at 400W so think QUALITY not POWER!! Antec, Q-Tec, Thermaltake, etc. are good. Make sure your RAM is branded: Crucial, PNY, Kingston, Samsung, Panasonic, Corsair, etc. In the first PC I built I used generic DDRAM. I had to replace one the modules within a year because it had died :-( Its hard to tell with yours - like you say it may be outsourced Samsung production. My advice would be to try getting hold/borrowing something like a cheap Q-Tec PSU and/or a crucial DDRAM (PC2100) stick to test what is actually wrong. Then replace these parts (one at a time). Linux has kernel support for avoiding dodgy areas of RAM but I would rather have RAM that works :-) Hope that helps. Robert Want to buy your Pack or Services from MandrakeSoft?

Re: [newbie] Is having LILO/GRUB on the MBR harmful to XP?

It's my first install and I've reduced the NTFS partition using Partition Magic 8.0 to make 9Gb of the 20Gb disk available. Ideally, I'd like to install LILO/GRUB on the MBR but I've read reports of non-windows boot loaders being considered a virus (by XP or the BIOS or Virus software I'm not sure which) and advice to retain the XP boot loader and to place LILO/GRUB on the boot partition. Does anyone know if this is still a consideration? I'd really appreciate it If someone could also tell me whether it's easier/better to create the Linux partitions with Partition Magic before starting the install or to leave the install process to create them for me. Thanks, David. Hi David, I have a dual boot Windows XP Pro and MDK 9.2 on my P4-M laptop. I had Windows XP Pro installed as a single NTFS partition (about 36gig). I just resized the Windows partition using the Mandrake partitioning tool (why use Partition Magic?? :-) and made a second partition (native Linux ext-3). I didn't even bother defraging the Windows partition!! I didn't bother with a shared FAT partition as Linux support for reading from NTFS is excellent or a swap partition (the laptop has 1 gig of RAM). I just installed MDK with a Lilo bootloader and it works great. I also have MDK Linux installed on a PC I use as a router/gateway with a cheapo MSI motherboard. This MB has a virus checker in the BIOS which checks the MBR for nasty viri. Unfortunately it thinks Linux is a virus so I just turned it off (its probably only needed by M$ Winblows users anyway :-). So don't worry about using the MBR... budge over Winblows and make room for a real OS :-) Robert Want to buy your Pack or Services from MandrakeSoft? Go to http://www.mandrakestore.com
[newbie] MDK 9.2 - Lost my open windows applets on Gnome panel on my Desktop :-)
Hi I tried to install the SUN Java add-in for web browsers and it went horribly wrong (it think it was meant for an old version of RH... Anyway I managed to lose the open windows buttons on my GNOME panel at the bottom of the screen. I know this is a bit stupid but I am new Linux and still finding my way around :-) Its annoying have to switch between apps using ALT-TAB!! How do I get the Applets back? Is it in one of the .gnome config files in my home directory or something? Cheers Robert = == Registered Linux User : 333230 MDK 9.1 Kernel 2.4.21 Download Yahoo!

Anytime someone asks this question I can never remember the command so I go to the newbie archives and search on urpmi.addmedia Thats how you do it :-) derek There's a lot of info on http://mandrake.vmlinuz.ca/bin/view/Main/UsingUrpmi but I'm not sure that repairing that damage is there. Perhaps someone could add it? Why not just go to the Software Media Manager (via the KDE menu or MCC) then choose Add and removable device?

Go to http://www.mandrakestore.com I am sure this is rehashing old information and also should point out I don't really know what I am doing... But this hack seems to work for MDK 9.2 :-) 1) I copied the CD's to my home directory into directories cdrom1, cdrom2 and cdrom3: cd /home/your home #Insert Disk 1 into CD drive cp -R /mnt/cdrom/* cdrom1 #Insert Disk 2 into CD drive cp -R /mnt/cdrom/* cdrom2 #Insert Disk 3 into CD drive cp -R /mnt/cdrom/* cdrom3) 2) I then used the MDK Software Media Manager to point to them. Just add entries for MDK 9.2 Linux CD1, ... CD2 and ... CD3 (or whatever) and configure the URL/hdlist as follows: CD1: file://home/your home/cdrom1/Mandrake/RPMS ../base/hdlist1.cz CD2: file://home/your home/cdrom2/Mandrake/RPMS2 ../../../cdrom1/Mandrake/base/hdlist2.cz CD3: file://home/your home/cdrom3/Mandrake/RPMS3 ../../../cdrom1/Mandrake/base/hdlist3.cz I know this is a complete hack (a more elegant solution would be appreciated :-) but it does seem to work. As the indexing lists are all on CD1 this saves you buggering about swapping CDs over :-) Robert = == Registered Linux User : 333230 MDK 9.1 Kernel 2.4.21 Download Yahoo!
