Power Supply Needed
by John Stoffel Oct. 13, 2005

Oct. 13, 2005

Hi all, Anyone have a Ilssan ISF 120SI compatible Power supply they'd be willing to sell me cheap? This is for an eMachines box that died in a lightning storm. It's for a couple with limited means and I just don't have any spares around the house at all. Specs for what I'm looking for: Input: 100-120VAC 3A Ouput: +3.3V +5V +12V -12V +%VSB 6A 14A 2A 0.3A 0.72A 120W It's a small power supply with a built in Fan that sticks out. More info (web pages for compatible ones) available on request. Thanks, John

Seeking someone to install SuSE Linux
by Andy Stewart Oct. 10, 2005

Oct. 10, 2005

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 HI everybody, Mel Korman came to his first WLUG meeting this past Wednesday asking for our help to get Linux installed on his laptop. Those of us who attended the meeting thought that his RedHat 9.0 might be too old for its installer to comprehend the external USB hard drive on which he had hoped to copy Linux, so I gave Mel the SuSE 9.3 Pro CDs which I had at the time, in the hope that he'd have a better time with the installation. Mel gave it a try at home but things are not working. Mel has offered to pay someone who would be willing to get Linux installed on his Thinkpad laptop (where Windows is also installed). If you are interested in helping Mel, please contact him directly at finkor(a)verizon.net. Thanks!

Meeting minutes from earlier this week
by Andy Stewart Oct. 7, 2005

Oct. 7, 2005

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 HI everybody, We had our meeting in one of the rooms right off of the Morgan Hall dining area. I think there were 7 or 8 of us, with two newcomers (welcome!). The discussion started with GRUB and some of its more interesting features vs. LILO, such as command line editing and adding graphics to the background. I had made a GRUB bootable CD prior to the meeting. GRUB has a large number of features, and we touched on only a few. After that, we somehow ended up on the topic of VNC: http://www.realvnc.com http://www.tightvnc.com <-- There was also interest in the "suspend to disk" feature of my laptop, which actually worked in a live demo. One person asked if it was possible to do this on a desktop machine (I don't think so....). In addition, Mel K. (newcomer) brought his laptop, onto which he wanted to install RedHat 9.0, which was having trouble recognizing his external USB hard drive. I gave Mel my SuSE 9.3 pro CDs and asked him to give that a try. Mel said that he'd keep us apprised of his progress. Pizza / soda followed at the Tech Pizza restaurant where we've gone after the last several meetings. Mel mentioned that he has interest in VistA (open source medical software). Try http://www.vistasoftware.org and google turns up other seemingly related links. Later, Andy - -- Andy Stewart, Founder Worcester Linux Users' Group Worcester, MA, USA http://www.wlug.org -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.5 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org iD8DBQFDRx4CHl0iXDssISsRAgHDAJ9ZQ4B0Morwv7EcxvAicO9fCxl2LgCdFxFg 5z9ZHpXjfJMuedYXi0ySZMI= =fVQp -----END PGP SIGNATURE-----

SuSE Installation process.
by Adam Keck Oct. 3, 2005

Oct. 3, 2005

Hello All, Does anyone have in-depth knowledge of the current SuSE install process? I want to get an install to exclude certain GIDs that we use in NIS when the install assigns GIDs to groups owned by packages. I found that I can assign the correct GID to an internal group in the autoyast XML file, but the package that uses that GID still gets a group assigned with that GID. Then result is duplicate GIDs in /etc/group. Ideally I would like to know how to get the installer to ignore certain GIDs. -Adam

Upcoming WLUG meeting reminder
by Andy Stewart Oct. 1, 2005

Oct. 1, 2005

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 HI everybody, Our next WLUG meeting is nearly upon us. Let's see if I can announce the date correctly this month: :-) Wed Oct 5th 2005 7:00 PM The theme of this meeting will be "What is the theme of this meeting?". As of late, that has been a familiar theme. Still, we manage to have fun both during and after the meeting, and that's a good theme (uh, thing)! Without intending to sound like a looping MP3, I'm always looking for someone to lead a talk at the meeting. I don't think I've ever turned anyone down so don't be shy. Having said that, I'm sure someone will come up with some wild idea just to be the first to get turned down. In the absence of a formal speaker, we can start by informally discussing GNU GRUB (http://www.gnu.org/software/grub) That topic will eventually lead us to other tangential topics. I was recently contacted by a person (Mel) who is having some trouble with Debian Sarge on a laptop. The difficulty has to do with loading X onto the laptop, which Mel will be bringing to the meeting. I hope a couple of Debian users appear at the meeting and can help Mel with this problem. At this meeting, I'll bring two books for the zero cost raffle: Linux Quick Fix Notebook Bruce Perens' Open Source Series Author: Peter Harrison Publisher: Prentice Hall http://www.quickfixnotebook.com Technical Writing (for Engineers and Scientists) Author: Barry J. Rosenberg Publisher: Addison Wesley http://www.awprofessional.com/title/0131498630 That's about it - see you at the meeting!

RH8.0 user in Worc. area
by Pete Wason Sept. 29, 2005

Sept. 29, 2005

Hiall! I'm wondering if anybody's using RH8.0 and could assist me in a general package updating/security audit/admin session. Nothing too crazy, I just need some help grokking alternatives to up2date (yum, etc.) and making sure my server isn't bleeding wildly from it's little pointed head. I live in Sutton.. Pete
