LInux+
by Rick Johnson 29 Jul '15

29 Jul '15

Hey folks. I've been studying for Linux+ lately. I have the Sybex book which covers lx0-101 and lx0-102 but I just discovered that these exams will be discontinued at the end of August and replace with lx0-103 and lx0-104. Has anyone taken these yet? I'm wondering what I'm in for. What is covered in these exams that isn't in the older versions? I can imagine that I'll have to dig into Systemd thoroughly but I'm wondering if I'll be able to just top up my knowledge from the 'net or is this a matter of starting all over? Thanks in advance

Re: [GTALUG] Fedora 22 Live Workstation Install - no fglrx - no pdftk

<snip previous> > existing solution. (AMD CPUs came with a disk of stuff instead of > paste and it is supposed to be single-use: detaching and re-attaching > a heat sink is not intended to work.) Could you describe this disk stuff in a little more detail? did you get the package locally? I think I am going to change the heat sinc on this unit. The one that came with it has this copper pipe threaded through it, Makes it look sort of like the headers on the 67 Mustang I once owned. UNlike those headers these ones look like all show and no go. Things got better after I flashed the bios. After I switched back to GDM Plasma did stop hanging and I got to see that desktop for the first time on this unit. Bonus; finer grained display ie. rotation was enabled and I was able to drop the resolution down to 800X600 to drive this old sansui tv I'm using. Stumbling blocks. I tried to underclock and crashed the bus. I haven's found any sic sigma tables for system recommendations; that plus the fact that overclocking is set by default to auto. Not even the decency to highlight the active settings in the menu at runtime, made me think where the heck is _that_ jumper0. I did read that north bridge switching is not enabled in later releases of this boards bios and I have since found there is an older bios with this FSB feature available. Although I usually hesitate to trim the north bridge clock. If you've got to trim a clock, trim the big clock first and see what acts up first. I wish I was better at math :-) And not so lazy. I reset the cmos without jumpering it off. When I reset it I could set the date but not the time. My working theory is that the ready state of the cross fire video bus consumes too many cycles. This board can drive four monitors. Since it's only driving one monitor, my first thought on stabilising was to knock the north bridge back a notch. I use tesseract's hocr to make pdf's text searchable so I always us video as an ad hoc performance monitoring thingy. By not over driving the display and dropping the resolution I got an extra 100 fps on glx gears. Vlc now plays dvd's without issue so it looks to me like tesseract should crunch a few hundered pages ok. There are Linux utilities from 2008 on the site; audio drivers and stuff and there is a check script: Detected configuration: Architecture: x86_64 (64-bit) which: no XFree86 in (/usr/lib64/qt-3.3/bin:/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/bin:/sbin:/home/russell/.local/bin:/home/russell/bin) X Server: unable to detect The question for me right now is, can I just add XFree86 libs to get quick time? Oh yea and whether or not it's worth it to modify the CPU heat-sinc. I know I haven't unseated it yet. That does't mean it hasn't been removed and reseated before this. I remember I use to be able to find little tubes of acetone to clean parts. I guess a trip to Active Surplus might find something similar, but I sure don't want to store even a litre of acetone at my place, just to use a couple of tablespoons of it now. Thanks Russell

Fwd: Linux Distros available in Toronto
by Myles Braithwaite 29 Jul '15

29 Jul '15

We got this email on our general mailing list. Does anyone know where you can purchase Linux DVDs in Toronto. -------- Original Message -------- Subject: Linux Distros available in Toronto Date: Mon, 27 Jul 2015 12:20:28 -0400 From: [reacted] To: hi(a)gtalug.org Hello. I am newly interested in Linux and it's variations, and am looking to purchase a distro on DVD.....trouble is, it seems that I cannot find any vendors locally, in Toronto that has them available...and my "google-fu" is usually pretty good...it was while searching that I found your User Group. I can find sellers in the US, but would prefer to do this local...and "The Linux Store" seems to be off line...Linux Cafe is no more. Could you point me in the right direction as to where I could get hold of linxu distros in Toronto on CD/DVD at reasonable cost? In particular, I am looking to get hold of Knoppix Live DVD v7.4.2, as that seems most suitable for me based on my reading. Your assistance would be greatly appreciated...hope I am not imposing on you by this request. Thank you.

Fedora 22 Live Workstation Install - no fglrx - no pdftk
by Russell Reiter 28 Jul '15

28 Jul '15

I recently acquired another older MB, ASUStek M3A78-EM, Athlon 64 X2 Dual-Core, 4Gb ram & onboard Radeon and I thought I'd give the latest Fedora Live a try. It installed well enough and Gnome pretty much worked except for the lack of fglrx in the open source drivers. In fact KDE Plasma doesn't work at all. In the Gnome desktop however, any intensive video apps such as VLC etc overheat the CPU and crash the unit. It looks like I'd have to backport X in order to install the proprietary Catalyst drivers for this particular GPU. HTML 5 videos on the net do work, but eventually the unit overheats and dies. I switched to lightDM and that's a little better but still not up to speed. It seems that yum has been dandified for this release but when I tried the new dnf update it failed to connect to the repositories. However, yum-deprecated did update the kernel and after that update dnf was able to function as intended. As I am always a sink or swim kind of guy and because a few of the individuals I support have switched to Fedora, even though I usually install Debian, I decided to try this as my workhorse for a while. I am looking around for a more recent PCIe video card in my price range, which usually hovers around free or the price of a hamburger, but failing that I'm pleased overall with the performance of the business end of things. Well there is one exception, no more pdftk support. (Licensing issues with iText5+) My problem. I often have to combine several complete and already numbered pdf documents into one consecutively numbered tabbed document. I use a shell script like this one below to number the combined documents. I include this in case others on the list might find it handy. I didn't author it, I found it on the net somewhere and would credit the original author, if I could find my notes this morning. enscript -L1 -F --header-font=Times-Roman10 -b '||$%' -o- < <(for i in $(seq "$(pdftk "$1" dump_data | grep "Num" | cut -d":" -f2)"); do echo; done) | ps2pdf - | pdftk "$1" multistamp - output "${1%.pdf}-header.pdf" This adds a header with the page number in 10pt text to the upper right corner of each page. Then I use pdftk to burst the document again and then blend in the tabs like this pdftk TabA.pdf file1.pdf file2.pdf TabB.pdf file3.pdf file4.pdf cat output newfile.pdf after each page is separated and numbered. It's a bit kludgey on larger docs but for small quick work it's ok. I was hoping to automate it more eventually. So if anyone has a recommendation on a more linux friendly video card of somewhat older vintage, or a command line tool to replace pdftk I'd appreciate it. I note that there are several GUI tools now available to assist with sorting pdf pages but I was really hoping to find something in the command line arena which I could then poke into this script. Thanks Russell

XFCE on regular Red Hat
by David Collier-Brown 26 Jul '15

26 Jul '15

For a long time, I've been using the Fedora XFCE spin, but wanted to build a new for-work dev machine and got RHEL 7.2, so I would have a supported version to host recent tools on. Fedora is fun, but tends to lag in app versions while being at the bleeding edge in kernel versions, which is fine for a toy machine, but the inverse of what I want for a machine to make money with.. 86_64 GNU/Linux Alas, RHEL 7.2 seems to be much *more* broken than Fedora fc 21 Yum can't even do a groupinstall, and half the required packages for xfce are in neither the Red Hat nor the EPEL repositories. Building XFCE from scratch exposes even more missing dependencies This seems odd, as many people with slightly earlier 7.X releases did $ sudo yum install epel-release $ sudo yum groupinstall "X Window system" $ sudo yum groupinstall xfce and were done. Is this just a bad release, or has RH been degrading while I was using something else? Should I downgrade to 6? Use KDE? Switch to a different distro? What are you folks using for prod? --dave $uname -a Linux miles 3.10.0-229.7.2.el7.x86_64 #1 SMP Fri May 15 21:38:46 EDT 2015 x86_64 x86_64 x -- David Collier-Brown, | Always do right.

Luks on Ubuntu 14.04
by Randy Jonasz 24 Jul '15

24 Jul '15

Hey everyone, I've been trying to resolve an issue unlocking a luks encrypted partition on boot using Ubuntu 14.04. I've set it up to automatically unlock after the root partition's password has been entered by adding the target entry into /etc/initramfs-tools/conf.d/cryptroot. I have 6 drives in this machine and 5 unlock fine. The 6th errors out with unkonwn fs or bad options or password. I can unlock the partition after boot using the derived key from cryptroot. I've tried to zero out the drive and start over but the problem persists. Can anyone give me any pointers on how to solve this? The drive is used as a cache drive for the zfs file system. Thanks! Randy
