suse-9.3 ...32 or 64?
by Gregory Avedissian 30 Dec '05

30 Dec '05

I just put together a new machine for a friend. Sempron 3100 on ASUS K8V-MX. It was a rush job, because the computer she was using died. (Same one I wrote about recently that was having lockup problems - pretty sure now that it was the power supply. The last time she tried to turn it on, a big spark came out the back, and that was the end of it. Memory and vid card still test good.) So now that she has a shiny new 64-bit system, I'm wondering whether to go with 64-bit OS or stick to 32. I haven't had much time to research it, but I understand that there are some problems with Macromedia Flash and Java, which she needs. Some of the reading I've done suggests that you can install the 32-bit version of Firefox with the plugins to get around this. Anyone know if it's really as easy as that? Are there any problems with running 32-bit software on a 64-bit OS? Any particular bugginess with 64 that I should know about in advance? She runs KDE desktop and uses Gimp a lot. Oh, one other glitch I ran into - I tried to do the network install, but the boot cd doesn't have the kernel modules for the LAN chip. I was instructed to go to the install cd and make a "modules 3" floppy. There is no modules 3 image on the cd or on the ftp site, but there are images for "bootdisk1, bootdisk2, etc." Do I have to make the whole set and install from floppy, or is there a way to find out which disk has the right module and just use that with the cd? Or could I just put an older card in it for the install and then change the network card setup afterward? I'm thinking the latter would be easier than finding five or six blank floppy disks to use. Thanks, Greg

With specific respect to compiling, some apps I regularly compile -- especially Scribus -- require that in the ./configure stage you include --enable-libsuffix=64. In this particular case, it's because the Qt libraries are sensitive to the bit-ness. The BUILDING file should indicate such requirements. HW

FC2 and FC3 to FC4 ... ?
by Theo Van Dinter 30 Dec '05

30 Dec '05

Hey folks, I have an FC2 and FC3 machine which I want to get upgraded to FC4. In the past, I used to spend an hour or two doing this type of thing manually which was a pain but generally got the job done ... This time around I was thinking of either using yum or burning some CDs and doing the upgrade method (which the Fedora guys recommended to me). Anyone have suggestions about what method works best? Any gotchas I should worry about, etc? Thanks in advance! :) -- Randomly Generated Tagline: "If you lend someone $20, and never see that person again, it was probably worth it." - Zen Musings

Busybox / mips / embedded Linux question
by Andy Stewart 30 Dec '05

30 Dec '05

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 HI gang, I am playing with a single board computer (SBC) in an attempt to make a diskless, fanless, silent firewall. Specifically, its the RouterBoard 532 (http://www.routerboard.com) The processor is MIPS based (4Kc). I've been using the buildroot software (nice!) which made creating the cross compiler enviroment considerably easier than my previous (failed) attempts at doing this by hand. My cross compiler environment is now working quite nicely. I have created an environment where I have loaded software onto a compact flash card and booted Linux 2.4.30 on this box. I have logged in and gotten the box talking on the net. All 3 ethernet ports function, as well as ssh and dhcp. Sweet! My next step is to take the SuSE firewall scripts (they are GPL) and run them on this box. However, I'm hitting a wall that I don't think I should be hitting. Within busybox, command substitution and pipes don't work on this MIPS box (but they do work on my x86_64). command substitution example: echo `cat /etc/hostname` pipes: ls -l | grep foo With neither of these working, real scripts don't work too well. :-( I've traced the source code (gotta love free software!) and the code fails whenever it calls the function dup2(). I'm not sure why dup2() fails, but it does, returning EBADF (bad file descriptor). I tried installing bash and noticed exactly the same thing. dup2() seems to be implemented as a system call into the kernel, but that's where I get lost. I've been scouring the net and cannot find an answer. I must be doing something wrong, but I know not what. Does anybody have any helpful hints? Thanks!

The situation you describe about the removable drives mounting in /media suggests it is using udev, hal, d-bus and ivman. Your home system should be using udev, but not sure if it has hal or d-bus; even if, doesn't sound like it has ivman. I'm not so sure about how to do this in FC, I'm a gentoo guy, but you'd need to have all of those installed and set up. This might be of some help: http://gentoo-wiki.com/HOWTO_ivman. You need udev and d-bus for hal, and then just need to start the hal daemon (hald). Then start ivman, and it should autodetect devices plugged in and put them into /media. For example, /media/usbdisk0 would be the first partion of the first usb disk plugged in (I do believe). It'll add new devices to your /etc/fstab. You can, however, have a bit more control over this, setting up a udev rule to make your disk use a specific device file, for example /dev/mydrive and then put a listing in /etc/fstab to mount /dev/mydrive at /media/mydrive. Then, when plugged in, udev will create the /dev/mydrive device file and ivman will detect it's creation and readiness and mount it at /media/mydrive. Spiffy stuff. For more information on writing udev rules: http://gentoo-wiki.com/UDEV_Overview#Writing_custom_udev_rules.

usb drive -- hotplug/automount
by Bill Mills-Curran 27 Dec '05

27 Dec '05

I have a question about hotplugging & USB and some differences I see between 2 different FC3 systems (home & work). **** Home Initially, I configured my drive at home. I did NOT have the menu item: Preferences -> Removable Storage set to "Mount removable drives when hot-plugged". Without realizing that this was an option, I used manual entries in fstab: # usb drive LABEL=usblinux /mnt/usb/linux auto defaults,user 0 0 /dev/sde2 /mnt/usb/windows auto defaults,user 0 0 /dev/sde1 /mnt/usb/camera auto defaults,user 0 0 This worked well & good. I was happy to be able to mount the partitions as a user. Note that the linux partition has a label "usblinux". Then, I moved the drive to my work machine. **** Work I plugged the drive in and was surprised to find that both partitions automatically mounted in /media: /media/usbdisk /media/usblinux I also saw that entries were added to /etc/fstab, reflecting the mount points and device names. I recognized this as better action. Returning home... **** Home Plugging the drive in, I confirmed that nothing was happening in /media. I found the entry to automount the drive in: Preferences -> Removable Storage and enabled it. I unplugged and plugged the drive, and it mounted with this from df: Filesystem 1K-blocks Used Available Use% Mounted on <snip> /dev/sde1 72801276 1704196 67398920 3% /mnt/usb/camera /dev/sde2 4176756 96 4176660 1% /mnt/usb/windows This is not what I wanted. It used my fstab entries, and it picked the "camera" entry over the labeled entry. OK, so I deleted the fstab entries & tried again. This time nothing mounted. **** What I'd like to happen. 1. Mount when plugged in. 2. Don't specify the device -- after all, some other (new) usb device could disturb the device name. How do I get there? TIA, Bill

Exim/MX/Mail forwarding
by Michael Zarozinski 27 Dec '05

27 Dec '05

Hi, We have 2 dedicated servers, I'm hoping someone can help save me some time and keep me from messing up the servers! Our 2 servers are: Server "A": 111.111.111.111 Server "B": 222.222.222.222 (not the real IPs obviously!) I've configured Exim to allow us to send email to a domain literal (so mail sent to michaelz(a)[222.222.222.222] works) What we'd like to do is have ALL email sent to server "A" go to server "B"... I know this can be done with MX files, but I'm not sure about setting up "domain zones" or if it's easier to just change some settings in Exim. Thank you! Michael Z

USB drive & logical volumes
by Bill Mills-Curran 26 Dec '05

26 Dec '05

Santa brought me a nice 80 GB "portable" USB drive. My intended use is a combination of backup and transporting personal files to/from work (I want to remove them from my work hard drive). Both home and work systems are FC3, but may be FC4 sometime soon. I was ready to partitioning (4 GB fat, remainder ext3) when I started reading up on logical volumes. They seem pretty neat, but I wonder if they are useful for a portable drive. In particular, I can see that some/all of the definitions for the group and volume are in /dev/mapper, so I'd have to duplicate some of the setup on both machines. Any recommendations or experience? Would I be better off with physical partitions for this use? TIA, Bill

I have been using Linux for 4-5 years no so I am definatly up for the task. I haven't had much experience with setting up a Linux router/firewall, but I think my other experience will be enough. Part of doing this project is to learn more using Linux as a router. I heard about the crippled WRT54G from slashdot and few other places. According to OpenWrt's wiki version 3 of the WRT54GS has 8MB of flash and 32MBs ram. However version 4 they cut it in half. Anyway thanks for the info.
