Sold on Ubuntu. . .. .
November-20, 2012 by: JonathanCalloway
From: JonathanCalloway ------------------------------------------------------ Hi! I have been using Fedora for over two years now. However, I grew very weary of updates (especially kernel updates) breaking things like wireless and VMWare Player. I couldn't get VMWare Player (4 or 5) running under Fedora 17 no matter what I did. (Before someone flames me about not using VirtualBox, I need VMWare Player for the classes I teach). Two weeks ago, I finally had enough. I downloaded Ubuntu 12.04 and used it to blow away my Fedora partition, and star from scratch. Within two hours I had a fully functional system with all my data (email accounts and Google Calendar in Evolution) and applications installed. I was feeling pretty happy until VMWare player started complaining that I didn't have enough swap space for it to run optimally. So, I downloaded System Rescue CD, and used GParted to decrease my ext4 partition, and increase my swap space. Viola! Ununtu booted right back up and now VMWare Player doesen't complain anymore. I'm still getting used to Unity. I think I'll give it a few more days before I start installing other GUIs. At any rate, the last time I used Ubuntu was about 4 years or so ago, when I messed around with Ubuntu Studio a little bit. I must admit, I am pretty impressed with how far it has come.

So. . . what's the difference?
June-04, 2012 by: Jonathan Calloway
From: Jonathan Calloway ------------------------------------------------------ Greetings! I have been thinking about trying to build bootable Linux machine using LFS for learning purposes. However, I heard a very interesting podcast today about Gentoo. While I've heard of Gentoo before, I didn't realize that it requires you to compile your own kernel etc. That got me to wondering, if you want to 'learn', what would the difference between using LFS and Gentoo be? Also, what about Slackware? All three give an installation experience that has been automated in recent years by Anaconda and the like. So, I will be interested in finding out what your collective opinions are. Thanks! Jonathan Calloway
CHUGALUG Meeting - 5/11, 12pm(ish), Coffee Shop at the Doctor's Building
May-04, 2012 by: Eric Wolf
From: Eric Wolf ------------------------------------------------------ NOTE: The Coffee Shop accepts CASH ONLY. I'll be in town for the weekend. So I'm calling the meeting. It's entirely social in nature. For those who don't know, the Coffee Shop happens to be where CHUGALUG was formed. Trying to dig back into ancient history, Higher Technology Services was upstairs in the Doctor's Building. They ran a sizable FidoNet node. Regular lunch meetups occured in the Coffee Shop. Eventually, Mike and Dan decided the BBS needed Usenet feeds so they cobbled together a fractional T1 and, with some help from Robert Wilson, got a pre-1.0 kernel Linux system to connect. Then they leaned about SLIP and realized the same hardware could provide direct connections to the 'Net. Thus was born Chattanooga Online at a time when Mosaic was still a science project at NCSA, the nearest 9600 baud modem was America Online in Nashville, and Windows was for Workgroups. Eventually, HTS/COL moved downstairs directly across from the Coffee Shop. CHUGALUG was formed as a LUG focused on advanced applications of Linux (specifically, we never held installfests like CALUG). The name CHUGALUG came from Larry Burton, one of the Chia regulars. So there's history in them thar tables! -=--=---=----=----=---=--=-=--=---=----=---=--=-=- Eric B. Wolf 720-334-7734
Precise Pangolin
April-29, 2012 by: John Aldrich
From: John Aldrich ------------------------------------------------------ Ok, I give up on Pangolin. My laptop is unuseable with KUbuntu Pangolin installed. I'm going back to Ocelot. It worked, although it was slightly buggy. I didn't have to worry about manually hacking the grub.conf file to add "nomodeset" to the command-line for the kernel, and my desktop didn't crash every time I switched to a VT and it DIDN'T take 10 minutes to load everything. This is NOT an "old" laptop... it's got like 4 Gigs of RAM, and Ocelot was fine with it, so I'm going back to Ocelot. Someone let me know when they have the bugs worked out of Pangolin and I'll switch. I'm guessing they'll have the bugs worked out about the time they release Quiescent Quetzel, so I'll just stay one release behind and be happy! It's not like I'm trying to use my laptop as a desktop replacement or anything. All I want to do is browse the web with it, but Pangolin just didn't like my hardware, I guess. :(

Need help getting EMC PowerPath working in RHEL 6.2
April-04, 2012 by: Lynn Dixon
From: Lynn Dixon ------------------------------------------------------ I have a RHEL 6.2 64bit install thats running on a Cisco UCS blade. I have an EMC Symmetrix VMAX LUN that is given to the machine and it has 4 FCoE multipaths setup. I installed the OS using "basic storage" and did a standard run level 3 install. Redhat recognized the multipaths and just setup dm multipaths automatically. The machine ran fine with no probs. Then I decided to install the latest PowerPath .rpm (got 5.6 from the powerlink website today). So, I commented out everything in /etc/multipath.conf, and disabled the multipath services from running. Rebooted, and then I installed the PowerPath .rpm. It ran, no errors, so I did the license registration. Heres the kicker, I an run powermt list dev=all (I think thats the command) and it will succesfully show me all of my FcOE paths, so I thought it was golden. I did powermt save, and rebooted. Poop hit the fan. RHEL will boot, go through the lower numbered inits, and even mount and fsck the LVM volumes I am using.....but, once it gets to the PowerPath service in init, it kernel panicks, and just refuses to boot at all. The only way I knew to get it back was to boot to resuce, and move the powerpath scripts from /etc/init.d to /root and reboot. Any one else come across this? It know it has to be a simple fix...or I hope. Thanks!
The advantages of Android being Linux
April-04, 2012 by: Chad Smith
From: Chad Smith ------------------------------------------------------ I've been thinking a lot about tablets lately. I have bought and sold a good number of them - several different operating systems - and have played with as many as I could get my hands on. I have kinda been wondering - what advantages - if any - are there to Android being Linux? I realize from Google's perspective it makes things easier, not having to rebuild the wheel in making and maintaining their own kernel... But is there really any other advantage? To my understanding, you can just run any old Linux application on Android - it has to be specifically ported to Android before it will work. And I realize, too, there is at least some sort of a victory for Linux supporters saying "Linux has gone mainstream!" But - pragmatically, for users - and maybe for hardware makers / app developers - does it really matter if it's a Linux kernel or a WebOS/Palm kernel or a BlackBerry kernel or some mythical custom Google kernel, etc.? And if it does - why? There's no point this this question other than idle curiosity. It's not any kind of attack or anything else. *- Chad W.

New Build Distro Suggestions
March-21, 2012 by: Randy Yates
From: Randy Yates ------------------------------------------------------ I'm about to build a new computer tomorrow for my main desktop, and I thought I'd bring an old subject back up. What's your favorite distro and why? I'm strongly leaning toward Debian Testing because I love Debian but I want newer packages. I'm not a big fan of Gnome 3 or Unity, though I may settle with Gnome Classic. I'll be developing, using Netbeans/Eclipse, Blender, The Gimp, Inkscape, and a few others. I'd like good multimedia support especially when it comes to good audio configuration out-of-the-box. I have an MS Live Chat headset that worked perfectly in one distro (I believe it was Ubuntu) but takes a bit of time to get functioning properly in Debian. How's 64-bit flash these days? At one time I was opting for 32bit OS installs with PAE kernels so I could use all my RAM just because 64bit flash wasn't agreeable. Let me know your thoughts. -- Google reads my email!
Weird message returning from hibernation
January-02, 2012 by: John Aldrich
From: John Aldrich ------------------------------------------------------ So I have this Compaq Presario F750 that's been giving me occasional weird errors returning from suspend. I'm getting an error "ATA3: revalidation failed" and an error number, but I don't recall the error number. Doing a quick Google search I see that others have had similar problems, only they fail to boot. Mine will boot just fine, it's coming out of hibernation/suspension when I occasionally get that error. System is running KUbuntu 11.10 with kernel 3.0.0-14
WHAT THE HELL HAPPENED to the MACH64 module!?
December-30, 2011 by: Rod-Lists
From: Rod-Lists ------------------------------------------------------ I have and old lime green iMac(i dubbed the crabapple) that I have run x on before. somewhere about when Ubuntu went chocolate the we started having issues with x. But before you haters start it is not ubuntu. I've been trying Debian squeeze now and getting the same problems. Screen goes black and power button yellow. Comes out of it when you switch to a cli tty. X messages state mach64 module not found. Some research shows that this is an issue on sparc and intel as well. Red Hat, arch it doesn't matter. So who the hell broke ATI support in the kernel? XORG is fickle & heathen god!

SATA controller
November-10, 2011 by: John Aldrich
From: John Aldrich ------------------------------------------------------ Ok, I'm finally getting around to trying to upgrade my machine and replace the failing boot drive. Only problem is, I'm out of SATA connections. :( Anyone got a recommendation for a good, linux-compatible SATA controller? I *do* have PCIE slots on my motherboard, and I think I have one PCI slot available (or will have once I take out my IDE controller.) I see a Highpoint Rocket 620 on NewEgg for about $30 that's SATA3 and PCIE 2.0, backwards compatible to PCIE1.0. Is that a good card? According to NewEgg it's Linux compatible with kernel 2.6.19 and above (I'm on Kernel 2.6.40, so I've got that covered!) I just thought as long as I'm going to be buying a SATA controller, I might as well get the most bang for the buck! :D Thanks!
Anyone configured an Avocent ESP16 Serial port hub (Serial over ethernet)?
October-27, 2011 by: Lynn Dixon
From: Lynn Dixon ------------------------------------------------------ So, we have RHEL6 machine that is connected to several serial devices that do monitoring in a lab over a serial-to-ethernet hub using an Avocent ESP16. I have the kernel compiled and the driver installed from Avocent correctly, and the OS sees the new serials. The people that make the instruments cant get the OS to "see" the devices stating that the ports need to be configured as such: Port type (Terminal) Configure Port (Incoming only) Speed ( 9600) Data bits (8) Parity (None) The driver software created 16 tty devices in /dev that are called ttyQ01e0 through ttyQ01ef How do I configure these ports in unix with those parameters (N-8-1) at 9600 baud.? I have never messed with serial before in Linux :(
