OpenWrt
by Mike Dec. 29, 2005

Dec. 29, 2005

At the last meeting we briefly discussed building a Linux Router from a single board computer. I was poking around the net and found the OpenWrt project. I'm curious if anyone has any experience with OpenWrt? Happy Holidays, Mike OpenWrt: http://wiki.openwrt.org/FrontPage

usb drive -- hotplug/automount
by Bill Mills-Curran Dec. 27, 2005

Dec. 27, 2005

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 Dec. 27, 2005

Dec. 27, 2005

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 Dec. 26, 2005

Dec. 26, 2005

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.

Re: [Wlug] Reliable Linux Laptop Vendor

Sorry, I don't know what a Linux ditro is. Yes, I am looking for a reliable vendor that offers laptops with Linux pre-installed. Any advice on the desktop program, i.e. which is better? Lindows? Red Hat? Linspire? and all the others out there? At the moment, I'm using Open Office, Thunderbird and Firefox on an old 98SE Dell Inspiron 3500, still ticking after all these years but slow. Additionally, down the road I will be researching video capture and editing suites (open source or otherwise) suitable for a Linux environment, but for now I'll be happy with the basics--an office suite, email and browsing. My bottom line is migrating from dependency on proprietary operating systems, versatility and reliability. Thanks!

Marie, I constantly see http://www.emperorlinux.com/ in the Linux magazines that I frequently read, however I can't say I've ever bought one from them. Emperor offers a variety of "distros" including my favorite "Ubuntu". Their prices seem a bit high, but might make a good point of reference at the least. Being strapped for cash myself I decided to get a used laptop on Ebay and trust my luck. For just a few bills I got a Compaq Armada M700 (which I am writing this email on right now). It's processor is only a P3 @ 1GHz, but I appreciate it more and more everyday. Ubuntu Linux installed flawlessly on it and I even got a Belkin 802.11b/g wifi card working without a hitch.

DNS/MX Question
by Michael Zarozinski Dec. 20, 2005

Dec. 20, 2005

Hi all, I'm new at this Linux thing and have a few questions about some servers I'm setting up. We have 2 dedicated servers which we have complete control over. One server is our production server (I'll call this server 'P') used to host our online games (AllinPlay.com) the other is for development, testing, email, etc (I'll call this server 'D'). These are physically seperate machines. Here's how I'd like to set them up: * Server 'P' is only used for hosting the games. It has the FQDN "AllinPlay.com" * Server 'D' only has an IP (no FQDN). - I'd like 'D' to be accessable via a subdomain such as: devel.allinplay.com - I'd like 'D' to handle all the mail for the allinplay.com domain. Users will get the mail from 'D' via a client such as Thunderbird So my confustion comes in as to how to set the DNS/MX/A/AAA records. If anyone can shed some light on this I'd be very greatful! Thanx! Michael Z

logging level in syslog
by Gregory Avedissian Dec. 17, 2005

Dec. 17, 2005

How do I increase the amount of information that gets logged in /var/log/messages in suse 9.3? From what I can gather, I need to edit /etc/sysconfig-ng/sysconfig-ng.conf.in. Is it just a matter of changing this line - filter f_warn { level(warn, err, crit) and not filter(f_iptables); }; To this? filter f_warn { level(debug, info, notice, warn, err, crit) and not filter(f_iptables); }; Or would I edit /etc/sysconfig/syslog? # Default loglevel for klogd # KERNEL_LOGLEVEL=1 If so, what number should replace "1"? Or something else? The reason I want to do this is to help a friend diagnose a problem with lockups. Sometimes one program locks up, and sometimes the whole computer locks up, and the reset button is the only way out. It happens when she gets a lot of stuff running (e.g. several firefox tabs, several gedit tabs, konqueror, and gimp-with many edits on the same file.) There's nothing useful in the system log right before this happens. Thanks, Greg

Success, almost, with GNOME
by Ken Jones Dec. 16, 2005

Dec. 16, 2005

Per the suggestion of Chuck Anderson I logged in under a new account. GNOME desktop worked just as it should. So I removed all of the /home/kjones/.gconf directory and logged in again as myself. Still it did not work correctly. In particular the right click on empty space did not work. I did a "diff -r" on the two (now default versions I suppose) .gconf directories. They seemed the same save for unique identifiers. Where do I look to find the differences? One other question. The Applications launcher on GNOME does not contain the LOG OUT feature. I know the command "shutdown", but I can not find a command to Log Out. Is there one? What is it? Ken Jones

Thanks everyone. I am a KDE fan also. I went to GNOME as an experiment. I have a memory leak problem with CORE 3 such that every week or so I need to reboot. (soxview shows SWAP free space slowly getting smaller and smaller) It turned out that this behavior is independent of windows manager. A question. Whom do I contact at Red Hat to propose that they help the Fitchburg Public School District migrate to LINUX server based "best office practices"? Ken Jones

getting that cpu to sleep ...
by brad Dec. 13, 2005

Dec. 13, 2005

greetings, I have a question for those linux programmers out there. i'm writing a program on linux (kubuntu to be specific) that requires high-precision timing, somewhere on the order of 100 to 1000 micro seconds. I get very good timing out of a loop written such that a while() loop checks the system clock after every iteration and comparing that to the desired wait time, like so (pseudo_code): while(time_passed < wait_time) { time_passed = get_time() } ... The problem with this approach is that the process uses 99% of the CPU since it just spins the CPU until enough time has expired. My question: is there a way on linux (in C) to have the CPU sleep or send it a no-op such that it's not just eating up cycles until time expires? I have looked at nanosleep and usleep, however they appear to only have precision to 10ms which too latent for my needs. Thanks, --Brad

Problem with gnome, Fedora core 3
by Ken Jones Dec. 10, 2005

Dec. 10, 2005

Gentlemen and ladies, My Fedora Core 3 - which has been yum'd up to date - behaves strangely when using GNOME as the windows manager. The right click on blank desktop space does not work. The right click on a panel to make a new panel does not work. The result is that I can not set up any launching icons on my desktop. There is no unused space on my one (bottom) panel. The panel-disappear icon is missing. Any ideas what controls this behavior and ow I can fix it? On a different machine I have a Core4 system running GNOME perfectly. Ken Jones
