Re: [Wlug] Seeking someone to install SuSE Linux

by Robert Schwein

Actually, the SuSE distro may have been a fortuitist gift for him. On July 8, 2004 Novell had become the first networking infrastructure vendor to reach an agreement with the U.S. General Services Administration to participate in the SmartBUY program for government-wide software purchasing. As of today, for many reasons including security, Novell's networking infrastructure software (SuSE is part of this) is still the only off-the-shelf software of this category in the SmartBUY program. The sole provider of open source software in the SmartBUY program, Novell offers three Linux bundles - a desktop solution, a "starter pack" server solution for smaller departmental deployments, and a more managed/full featured server solution for large environments. Vista has been around for over a decade and runs on various OS platforms. However, over the past year the government (initially the Veterans Administration) has been slowly replacing its Windows, and small islands of *n(i,u)x installations with SuSE. The only reason I happen to have any familiarity with this is because about a year ago the Federal Court system in this area asked me to migrate them off of RedHat and Windows over to SuSE. I was surprised but when I dug into what was going on, I understood. With WINE and Mono providing the Windows and .NET support on SuSE, the government is moving at an ever increasing rate in adopting the SuSE distro.

-----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

-----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.

Just wanted to say that the "suspend to disk" feature is available on a desktop machine. With Gentoo I use the 'suspend2-sources', and have had no problems with hibernating both my Athlon 64 desktop computer, nor Pentium3 laptop. A good howto is available on the Gentoo Wiki site, http://gentoo-wiki.com/HOWTO_Software_Suspend_v2 The instructions are fairly informative, that even non-Gentoo users should be able to use the howto as a stepping stone to getting the feature into their kernel.
