Re: Scientific-Linux: which version has bigger support date?
I've been using SL6.0 as my primary desktop OS since about 2-3 months before 6.1 was released. i was set to do the upgrade to 6.1, but noticed that with the round of updates that came out around 6.1 release time, I was running the same kernel rev. as 6.1. Since my system has been very solid, I decided to skip the upgrade to 6.1, and haven't had any regrets. However, since this is my primary OS, I have had to install some software that wasn't in the SL repos to meet my overall user-experience expectations. Mostly this has been to use newer versions than are in the repos, anyways. My general procedure has been to use the SL repos for system-level packages, use the EPEL repo for a few additional system-level packages, and install personal stuff as needed. Some of the stuff that I manually installed... -- Didn't install default OpenOffice, and installed LibreOffice instead -- Uninstalled OpenJDK, and replaced with OracleJDK -- Installed latest PostgreSQL instead of older repo version -- Manually download and install Adobe Flash -- I'm still running the default Firefox, but will probably manually upgrade -- I needed a newer Perl than the system install, so I used Perlbrew ActivePerl -- Other development tools... Eclipse, Netbeans, Komodo, Jedit, etc. -- JBoss, Glassfish, VirtualBox, etc. I'm only managing this stuff for one machine, but if I were doing this for multiple machines, I'd set up a Puppet/Chef/etc. server + local repo for special packages and centrally manage everything. Comparing SL6.0 to Fedora 14, SL6 is a bit behind in some software revs. (Like Perl 5.10.1 vs 5.12.3), and there is less to choose from in the repos, but it has been, for me, very solid as a desktop OS. If you're happy with FC14, I think you'll like SL6.x.

Great! But: We need a Linux distro that doesn't need a reinstall in every half year. (no, dist-upgrade is not an option!). We found the Scientific-Linux. So according to: https://www.scientificlinux.org/distributions/roadmap SOLUTION #1 if we install 6.1 with GNOME, and use it for Desktop purposes, then we will have updates until 2017-11-11. WOW!! That's more then 6 years! http://www.timeanddate.com/date/durationresult.html?d1=29m1=9y1=2011d2=11m2=11y2=2017ti=on This is f*cking great for an enterprise. SOLUTION #2 if we install the: http://www.osst.co.uk/Download/scientific/6rolling/x86_64/iso/SL-61-x86_64-2011-07-27-Install-DVD.iso.torrent that's a rolling release. Now I haven't used any rolling release based Linux distros so I don't know what that exactly means. Q: does it mean that if I install it once, then I never have to re-install it again because of a version upgrade, ex.: Scientific-Linux 7 comes out, and neither do I need to dist-upgrade? - Because rolling release means that there is no more version numbers?
How to install VLC player/Chrome/VirtualBox on Scientific-Linux 6.1?
Using other distribution's repositories is a bad idea, because ex.: Fedora doesn't has 6 years support of a given version of the OS. What is the best-practise for Scientific-Linux? What are the to-do's after a Minimal Desktop install? So the real Question: How can I install a fresh version of these apps on Scientific-Linux 6.1/64bit?: * VLC player (it's not in the default repositories and all I can find is an outdated VLC in rpmforge) * Chromium/Google Chrome? * Flash Player * VirtualBox * microsoft paint alternative :D http://unix.stackexchange.com/questions/21785/to-dos-after-installing-scientific-linux-6-1-for-desktop-purposes/ Or it is advised to use another media player other then VLC? there are many AVI/WMV/MP4/FLV/etc. videos with many codecs. VLC has many codecs (built-in?) that's why we need it. but fixme if there is a better media player for Scientific-Linux.
Re: How to install VLC player/Chrome/VirtualBox on Scientific-Linux 6.1?
VLC is in rpmforge. If you install the rpmforge repo: yum install rpmforge--release You should be able to install vlc: yum --enablerepo=rpmforge install vlc There is also an adobe repository: yum install adobe-release then install the flash plugin: yum install flash-plugin For virtualbox, you will probably just have to install via their packaged RPM: https://www.virtualbox.org/wiki/Linux_Downloads they have one specific to EL 6: Red Hat Enterprise Linux 6 (RHEL6) / Oracle Linux 6 (OL6) As for a paint alternative, there's GIMP available in the SL base repos, just: yum install gimp. Apparently you can get chrome running on EL6 by following this tutorial: http://blog.ask4itsolutions.com/2011/03/20/howto-installing-google-chrome-on-rhel-6-red-hat-enterprise-linux-6-32bit-64bi/ I haven't yet tried that though. -Chris On 2011-09-30, at 9:18 AM, lancebaynes87 wrote: Using other distribution's repositories is a bad idea, because ex.: Fedora doesn't has 6 years support of a given version of the OS.

gnome-volume-control error
Hi Guys, $ rpm -q -f gnome-volume-control gnome-media-2.29.91-6.el6.x86_64 Everything sound wise works well on my SL6.1 x64 machine except gnome-volume-control. When I fire it up, I get waiting for sound system to respond Any idea how to fix this? Many thanks, -T Hi Guys, Figured it out. Two dependancies are left out of the RPM. Solution: # yum install pulseaudio rtkit Filed a bug on it: https://bugzilla.redhat.com/show_bug.cgi?id=742660 -T
core count and kvm: 4 or 8?
Hi All, If I understand the process correctly, when specifying the number of guest cores in KVM, I am not actually specifying any particular physical core: I am specifying how many connections to the cores I can have open at once. I get the next free core, who ever that might be, up to the limit. I have an i7 processor (love it!) with four physical cores. But Linux thinks I have 8 cores due to hyperthreading. Here is where some confusion arises: Should I stick to four or fewer cores in my KVM guest, or should I go for all eight? I was thinking of six cores to leave some left over for the host. And an even number as some of Microsoft's fine software freaks at an odd number of cores (M$SQL server). Many thanks, -T p.s. l since no one is going to believe me about M$SQL and odd cores, this is straight from the horses mouth: http://support.microsoft.com/kb/954835 There are other instances, but I can not prove them. Things just cleared up with an even number of cores (X5650 with 6/12 cores)
Anyone have a favorite Hylafax client?
Hi Guys, Anyone have a favorite Hylafax client? I have been using J-Hyla-FAX. It works okay. I wish I did not have to convert everything over to Post Script before fax'ing. I presume printing directly to HylaFAX is out of the question. Many thanks, -T

So if you are planning on a SQL installation in the guest, you might want to stick to 1, 2, or 4 cores. -- Joel Maslak Former MS SQL DBA

Oh my goodness what awful software. Fortunately I am done with M$SQL for now. It might come back, but I hope not. Have you any wisdom on the four or eight core question? -T

Oh, you asked a good question, and I happened to write the SunOS port of that *years* ago, and contributed to the upstream vendor compatible Linux ports. Working with its author, Sam Lefler, was a privilege. Scary bright man, invented TIFF, one of the authors of BSD. The answer is that you have to get the target phone number into the system *somehow*. Your print queue would have to obtain the information from somewhere: that's why the Windows print queue based tools, like the PDF printers, pop a little window to ask questions. So a GUI that does what you want should be feasible. Hylafax, and the discussion lists, are hosted at Sourceforge: go aks over there and tell them i said hi. Also, unless your setup is odd, Postscript or tiffg3 conversion an handle dozens of file types, is automated, relies on ghostscript, and is managed by the typerules. Has it been a problem for you? If so, let us know or mention it to the HylaFAX groups.
