OT: Perl Help

Hi All, I recently bought a custom Perl script from a developer who did what I asked him to do. When I got the script, I realized it was not what I was looking for. It's a quite simple script, converting data from one database to another. I would like to add a simple web interface, something along the lines of click here to import, click here to process, click here to export. I don't have much money left for this project, but if anyone could help me or could recommend someone I could get this finished with reasonably, I would be very grateful. I think the majority of what I need could pretty much be boiler plate, its just a matter of making the script run from the web server instead of running locally via SSH tunnel. Thank you very much, Sidney Sidney-3Kd7Tu4o6f/sBN0MCq728g at public.gmane.org 416 782 2761 (h) 416 835 2761 (c) -- The Toronto Linux Users Group.

Incredible frustration at Grub/linux!

Hi, Do you have a separate /boot partition? GRUB uses the /boot/grub/menu.lst configuration file to build the boot menu. Open the file with some text editor, and find the entry for your kernel. It should look something like: title Red Hat Linux (2.4.20-24.9) root(hd0,5) kernel /vmlinuz-2.4.20-24.9 root=/dev/hda6 initrd /initrd-2.4.20-24.9.img make sure you are editting the right section for your current kernel. Actually, you should copy+paste the section and change the title (stuff in the "()") to something like "test" so if anything goes wrong you have your origional settings. Next, change the root(hdx,x) entry so it points to the partition containing your kernel. If you have a boot partition, then you probably don't need to change this (unless you are also trying to backup and test it), but otherwise it should point to your new root partition. The first x is the IDE physical drive ID (0->hda; although there are some strange issues that may change these mappings). The second x is the partition number. Change the root= in the "kernel" line to your new root partition. It is probably set to "LABEL=/" which will always point to your origional partition. Try replacing it with the real device (/dev/hdxx). Reboot and select the new entry at the prompt. If you encounter any more problems, can you please attach your menu.lst file and the output of: # /sbin/fdisk -l I hope this helps.

I'm not a grub user, but maybe some of this will be useful? Random Googles show this: http://www.gnu.org/software/grub/grub-faq.html#q11 http://lists.debian.org/debian-user/2003/debian-user-200308/msg05498.html http://lists.sistina.com/pipermail/linux-lvm/2000-October/005259.html http://lists.sistina.com/pipermail/linux-lvm/2000-October/005260.html http://linux-sxs.org/distros/gentooinstall.html (see #5) http://smtp.openna.com/pipermail/openna-users/2003-September/000044.html http://www.gentoo.org/doc/en/lvm.xml I'll stop now. Hopefully there's something useful in one of them. A few highlights include the following: IMPORTANT NOTE: if your *boot* partition is reiserfs, be sure to mount it with the "-o notail" option so GRUB gets properly installed. Make sure that "notail" ends up in your new /etc/fstab boot partition entry, too. 1. Install GRUB into the directory /boot/boot/grub instead of /boot/grub. This may sound ugly but should work fine. 2. Create a symbolic link before installing GRUB, like cd /boot && ln -s . boot. This works only if the filesystem of the boot partition supports symbolic links and GRUB supports the feature as well. 3. Install GRUB with the command install, to specify the paths of GRUB images explicitly. Here is an example: grub> root (hd0,1) grub> install /grub/stage1 d (hd0) /grub/stage2 p /grub/menu.lst -- Emma Jane Hogbin [[ 416 417 2868 ][ www.xtrinsic.com ]] -- The Toronto Linux Users Group.

Hi all, I have been -trying- to setup a server with a '/' filesystem of 'reiserfs' for later use under LVM and some HA software but I have been absolutely unable to get past the starting gate and on top of feeling flat out stupid I am also getting terribly frustrated. I want to do one, little simple thing - make a backup of '/' to another drive/partition and then reboot using it. It seems that absolutely no matter what I do, what file I edit or what I try to force the system (Fedora Core 1) INSISTS on using the original '/' (in this case '/dev/sda1'). I don't what the heck I am doing wrong but I am about to blow a gasket. I have never been so fsck'ing mad at Linux before. Why is it so damn hard to mount a different '/' partition?! Anyway, I am using Grub because it is the only boot loader available on Fedora. I have tried reading the docs and am doing so again after sending this to see if I missed something simple... Bah, if nothing else this is a rant that may help me cool down enough to find my problem. Sorry for the noise. Madison -- The Toronto Linux Users Group.

Could I ask you to expand on your two words a little bit by using the info in the man page in a concrete way, e.g show me how to access physical memory at address 0x200 to 0x205.
