Either legitimately confused or early onset....

I have successfully installed Fedora 6 Core. I included 'programming' services. It said that it would install SAMBA. It did not. System Services mentions the need for xinetd. 'Locate' finds 'xinetd' but it does not seem to run. smbd and nmbd are nowhere to be found. Sigh..... My machine only has 256M ram memory. The higher numbered FEDORA packages ask for more ram. I have a 'good' and never before used set of Fedora 6 .iso CD-ROMs. Red Hat and Fedora have gone their separate ways. I just found http://docs.fedoraproject.org/en-US/Fedora_Core/6/html/Installation_Guide/i…. Looks promising. Little did I know how much has changed..... Constructive suggestions would be appreciated. Maybe I should jump to CORE 13 or so...... Ken Jones (the elder)

Fedora 15 and Burning CD
by dulsi＠identicalsoftware.com 25 Aug '11

25 Aug '11

I want to burn a copy of fedora 15 32-bit on a CD but my installed fedora 15 64-bit isn't letting me. When I put in a blank CD it tells me it has 137.8 MB free and won't let me select that as a burn destination. It shouldn't be 137.8 MB free as a blank CD has more space. To get it working I decided to try burning to a DVD. Space seems correct there but again it doesn't allow burning.

SAMBA on Fedora 6??
by Ken Jones 25 Aug '11

25 Aug '11

Due to a series of incidents too complex to detail here, I have just rebuilt a desktop PC with Fedora 6. All seems fine except it does not contain SAMBA - at least I can not find the SAMBA executable on the 5 disc .iso CD set. It has been at least five years. I do not remember it being difficult back then..... I have gone to various places on the WEB that claim to have appropriate SAMBA versions only to discover they have been taken down. I tried the SAMBA in my FEDORA Linux 3 Bible DVD. (Many dependencies missing....) I tried the SAMBA in my SAMBA Black Book CD. I got no where. It's been soooo long. I like Fedora. Must I now go to Ubuntu? Ken Jones

Robotics and linux
by Ken Jones 24 Aug '11

24 Aug '11

Thank you, Kevin, As you can see from my video I have built a state-machine-only robot out of a radio controlled model level car and an Arduino Nano programmed in ArduinoC_0021. The idea has been to interest middle school teachers and students in 'How things work' in 2011. Education must be relevant. My cars can race each other around a room. Speed, competition and the 'real world' makes relevance. Modify the code and win the race. My project has been going on for over a year. Recently it has been struggling. After watching a video of the 2012 Lexus parallel parking itself and realizing that it is doing some mapping, I thought I would investigate 'real' robotic code. ROS was suggested, but it does not seem the right fit. Any suggestions would be appreciated. Ken Jones

ROS Robot Operating System
by Kevin Harrington NR 24 Aug '11

24 Aug '11

A much easier to use alternative to ROS would be our platform, the DyIO and the Bowler Communication Sysrtem. We use a platform independent communication platform to turn any computer into a robot. WPI is now using these controllers as the basis for all the intro and advanced robotics engineering classes. You would write code in Java (Standard Edition), execute the application of any OS, and communicate to the DyIO for all your I/O needs. We have a ton or tutorials and HowTo's for accessing the different capabilities of the DyIO. If there was some interest i could run a seminar about making robots with Linux... -- Kevin Harrington Neuron Robotics President and Founder

ROS Robot Operating System
by Ken Jones 16 Aug '11

16 Aug '11

I have designed and built a robotic 1/10 scale radio control car (See link below). I added an Arduino Nano to a HPI Sprint. I have been using Windows based Arduino C code. This package is too limiting. I am considering getting into http://www.ros.org/wiki which is LINUX based. "ROS (Robot Operating System) provides libraries and tools to help software developers create robot applications. It provides hardware abstraction, device drivers, libraries, visualizers, message-passing, package management, and more." Are any of you WLUG members ROS-ites? My Linux skills have degraded due to lack of use (and old age). Here's a pointer to a youtube showing my robocar being a robot and what it is built of. http://www.youtube.com/watch?v=J-rgkt8WDXQ Ken Jones Fitchburg

by E Johnson 09 Aug '11

09 Aug '11

Hi everyone, The annual WLUG BBQ is tomorrow! Time & location & contact info has already been posted on the list. We have salad, cheese & crackers, plus a few extra goodies, & the condiments. Dogs, burgers & buns are allegedly arriving. So we expect the event to be enjoyable. A few news items & reminders: 1. We have been fairly bug-free this year, which still seems to be the case. But it is raining now, so, we'll know when we now. 2. Our Driveway is for deliveries (tables/chairs, coolers, etc., but not for Event Parking. There should be adequate parking on Hudson St. If you have a special Parking need, please let me know: iris.gates(a)gmail.com 3. We do not have an icemaker. Whoever is bringing the non-BYOB drinks (the soda), please bring cooler plus ice. If you BYOB, please provide your own cooling technique (cooler & ice) 4. My apt. is on the 3rd floor, so note that the Facilities are a few steps up. 5. Someone has promised to bring a table. That would be greatly useful. Perhaps a second table, even a small card table, would be helpful. 6. BYO lawn chair. 7. Wireless will be on & accessible, but I have not tested it in backyard. 8. If it rains or hails or otherwise becomes inclement, we can adjourn to my apt. Tall people may need a hardhat, but we can cram in. 9. Arts Worcester event is going on in Elm Park lately; there are a few things to see, should anyone wish to take a short walk. Elm Park is only a few steps away. 10. Sign on light pole out front will say WLUG. A Penguin is allegedly arriving, but no clue where he will be located. ## Who is bringing plates, cups, forks & spoons? Could you please check in here before Noon Wed. (my final shopping trip)? TY. See you tomorrow! Liz J

Solved: X apps no longer work with sudo after upgrade to Squeeze
by Theodore Ruegsegger 09 Aug '11

09 Aug '11

I could have guessed I'd find the answer just after posting, but perhaps this will make it easier for the next googler. I had written: > Summary: After upgrade from Lenny to Squeeze, I can no longer execute > X apps using sudo in an ssh session. Why not, and how can I restore > this ability? A careful reading of the manpage for the /etc/sudoers file (man 5 sudoers) yields this insight, under EXAMPLES: # Run X applications through sudo; HOME is used to find the # .Xauthority file. Note that other programs use HOME to find # configuration files and this may lead to privilege escalation! Defaults env_keep += "DISPLAY HOME" It looks like the newer version of sudo no longer preserves $HOME by default (although, the above notwithstanding, it does keep $DISPLAY). Adding the following line to my /etc/sudoers restored my ability to run X apps via sudo: Defaults env_keep += "HOME" Hope someone else finds this helpful. Ted Ruegsegger

Hi gang, The WLUG BBQ is coming up next week, Wednesday, August 10, starting at 6pm. Thanks to those who volunteered to bring items, and thanks to our hostess Liz Johnson. We'll have hot dogs, burgers, bratwurst, all the fixings, some chips/snacks, salad and soda. The grill will be fired up if anyone has something else they'd like to grill, and desserts would be welcome as well. There will be a cooler or two and some ice for BYOB. People should bring a lawn chair for themselves if they wish to sit down. Based on past BBQ's, I'm expecting about 15-20 people, perhaps more. The address: 34 Hudson St, Worcester, MA (It is a green house, one house south of Elm St. Elm St runs east/west along Elm Park and Hudson St is one block east of Park Ave.) Look for a "WLUG" sign on the city light pole, as well as a big Tux Penguin. If you get lost you can call Liz at 508-471-4407. Hope to see you there! Chuck WLUG President

X apps no longer work with sudo after upgrade to Squeeze
by Theodore Ruegsegger 06 Aug '11

06 Aug '11

Summary: After upgrade from Lenny to Squeeze, I can no longer execute X apps using sudo in an ssh session. Why not, and how can I restore this ability? Details: I just got around to upgrading [1] a server to from Debian Lenny to Debian Squeeze. Normally I access it via ssh with X forwarding so that I can display any X apps on my workstation [2]. I have root logins disabled and use sudo instead when I wish to run an app as root. Under Lenny, I could execute X apps under sudo and they would display just fine, for example: sudo xless some-file [prompts for my password] [xless opens in a window on my workstation] Under Squeeze, the attempt fails with an error message: sudo xless some-file [prompts for my password] X11 connection rejected because of wrong authentication. Error: Can't open display: localhost:10.0 Googling "X forwarding sudo" gives me lots of explanations about .Xauthority and cookies but nothing that explains why I should now need to manage this myself when I didn't need to before. Can anyone set me straight? Ted Ruegsegger __________________________ Notes: [1] More precisely, I didn't dist-upgrade it (that's another story) but installed Squeeze from scratch, preserving the /home partition and repeating my original configuration steps. [2] This server doesn't run a GUI desktop.

Hi Jason, I would be interested in giving you a hand. I have experience with HTML, some with CSS. Haven't tried my hand at Javascript yet but have checked out a few tutorials and online learning. Have some past experience with SQL/MySQL along with Perl/CGI/DBI. It would be a great opportunity for me, as I'm seeking a transition over to web development.

MP3 playback in Fedora
by Eric Martin 03 Jul '11

03 Jul '11

I'm thinking about switch over to CentOS from Gentoo at work for a few reasons, two of which are the compile time and the ability to check packages against GPG signatures. That being the case, I decided to convert my desktop to Fedora so I can get my chops up on yum and the RedHat style distros. it's going ok and I'm getting pretty good at figuring out where to find things, and I'm even looking at writing an RPM or two where I need stuff. However, I can't seem to get MP3, Mpeg1 or Mpeg2 playback working, and I can't get adobe-flash to install via the nspluginwrapper. I've googled, installed a bunch of packages that people suggested and even checked what packages I have on my Gentoo system and installed some of those but I'm stuck. I have Adobe-Flash installed as well as nspluginwrapper, but the commands I find online aren't wrapping the plugin. I installed libmpeg2 and libmpeg3 but I still can't play movies or mp3s. Any suggestions? thanks, -- Eric Martin

Would anyone at all be interested in helping build a new website? I can't share too many details, as it will be commercial, but i need someone who has experience with HTML/CSS/Javascript/PHP/AJAX/MySql and preferably experience setting up a version control system (server). Parts of this project will end up being open source (the chat server for the web site already is). If anyone knows any of this, or even if they feel they can lend a hand with part of it, It would be much appreciated. More details will be given in direct emails, provided a good faith non-disclosure agreement is acceptable. No signing anything, just an email stating you agree not to disclose the details of this project, prior to its release. This project will benefit the open source community if it is successful. Thanks in advance, Jason Couture

Lights going dim, concerned about compouters & assoc. equip.
by E Johnson 02 Jul '11

02 Jul '11

Hi all, I think we have a bad refrigerator here, possibly problems also compounded by an inadequate elex cicsuit. Elex is owned & paid by landlord, who thinks this is "no big deal" & "happens all the time No problem." Maintence is not this building owner's favorite occupation. Person is on a tight budget just like most of the rest of the world. Proibem: Lights go dim whenever dying refrigerator comes on. This unit rins apprix 40 minutes per every hour, even on cool days with minimum opening/closing. I am concerned about longevity and function of my computers. power supplies, modem and router (I own these & they are nice). One printer already fried when Handyman shorted hot and cold elex together in the process of replacing one light swich in kitchen. Hope never to see him again, he's not a bright bulb. Is there some way to monitor the currrent on the elex line for several days and record what's going on? If so, does someone have a monitoring device that could be loaned and set up to do this? I am in Woircester near Elm Park, & am a very good cook. Have decent chairs & workspace with fast internet... could provide free beer & P1zzA or lunch if needed during setup period. Thanks mightily, Liz J

RHEL cluster question...
by David Hardy 14 Jun '11

14 Jun '11

Greetings, fellow Linux lovers; Ran into a little situation today where we need to cycle power/reboot a bunch of nodes that are down and out, by telnet to the relevant terminal server ports and the advanced management module. This involves multiple consoles, windows, command line, GUI, the works, as follows: Subject: RHEL cluster, 4.0 through 5.3. Issue: How to find IP addresses of terminal server ports which service individual nodes which are down and out. (need to telnet to them for troubleshooting/maintenance/rebooting) And: IP address and/or hostname of advanced management module which runs on the clusters . Some clusters have a "magic decoder ring" file that gives this information; most don't. Any thoughts? Workaround so far has been via eyeballing racks of blades and doing various arithmetic problems in our heads.
