Been a busy fellow ...

Well, aside from now pretty much running all EL7 on anything that it will run on, VMs included, and a massive security audit involving going over SELinux policies and firewall rules, I have had quite the time computing.

Got a repo up for Fedora 20 and EL7.  Sofar not too bad.  Had a private one (well was public but never showed anyone how to get to it).  Cleaned it up a bit and redid it so its public.  The focus is on getting software available to EL7.  So anything that isn't there is getting a query for srpms to rebuild.  If I have to go manual, or if the software is so new compared to whats there in the Fedora repos, I will host the newer version.  Priority for srpms is current release then as a last resort the rawhide rpms.  This has been working as a safe policy for nearly a decade of rolling up rpms.

Redid my vm running Mumble and other things.  Not a Debian fan in the slightest.  Reloaded it with CentOS 7 and its rocking hard.  A bit better performance too.  Kernel and better packages may be the cause... (had a few flaky .debs that I think were being a PITA.  Never learnt how to do .debs well).  A bunch of services are now finally offered officially and correctly.  Those who are to have access have been notified in one fashion or another.

Fixed my VM server somewhat.  Some bad SELinux policies and permissions and firewall settings.  Also applies to all VMs I host here as well.  All hail KVM and tuned!

Now its just to migrating my website and email (I know, been saying this for years now, literally).


CentOS 7 a few months in ...

Well, I have been using RHEL, Oracle, and CentOS on several of my machines each now for some time, but not on my main tower due to EL6 being inadequate for gaming (PulseAudio related mostly).  Well that changed shortly after CentOS 7 got dropped on us all.

C7 has been phenomenally great.  I have been very happy with RHEL and Oracle overall for servers, and that has not changed.  At all.  If I can afford the entitlement, I go RHEL, otherwise its Oracle.  But at least Oracle has a lack of usability for desktop usage.  Its really not well suited at all for this, as alot of necessary packages are just not there.

C7 + Nux + EPEL + ELRepo make things very very nice.  The one hangup for many is getting wine.i686 working correctly.  No need to struggle there.  I detailed what needs to be done here and in short :

  1. yum install glibc.i686 alsa-lib.i686 libXv.i686 libXScrnSaver.i686 libSM.i686 libXi.i686 libXrender.i686 libXrandr.i686 freetype.i686 fontconfig.i686 zlib.i686 glib2.i686 libstdc++.i686
  2. And then install PlayOnLinux
  3. Set PoL to use a non-system wine

Steam works great.

Chrome and Firefox work very well also.

Screen Recorder seems to be in proper order, although I havent toyed with it too much.

GNOME 3.8 runs very well.  As much as I played with other DE's, GNOME was better.  I have not, however, tried a MATE install yet or Cinnamon.  Cin always worked very well for its usability, footprint and stability.  

Server and client side, KVM is rocking hard, and I am loving it.  Glad I stopped paying for VMWare.  

And packaging up RPMs seems to be a bit simpler, now that alot of the Fedora tools are updated to a more recent rev, doing mock and yum-builddep runs are a walk in the park.

Long story short, aside from a very select few packages that are not present, I couldn't be happier.  Once again, Red Hat hit a homerun, and with the much more up to date libraries, things I depend on are going to be good at least until EL8 drops if not longer.


Going forward, once I can scrounge some spare time, I will be setting up a repo soon to host my packages I have rolled up to keep things clean on my end.  They are all clean packages that pass mock and rpmlint tests.  I will try to keep it only dependent on EPEL + base, but there may be a few issues that prevent that from time to time.  I will need to sit down and develop a battle plan for getting a build bot enabled and a way to track when new packages should and could be made to make life saner.

I also plan on actually getting them videos done.  I have a bunch of stuff for EL6 that is there and waiting for post, but porbably will be updated to be more EL6/7 centric rather than just the latest and greatest.  I won't touch EL5 anymore, far too ancient for my tastes.


KVM oopsie

For those that didn't know, KVM hangs bad when an NFS mount disappears.  I ran into an issue where  I forgot to delete an old NFS data share.  The current one was up, but I disabled the old node.  Well that went badly.  Eventually I figured out that other than fstab, I needed to remove the xml file and a symlink to it -- etc/libvirt/storage (the xml file) and /etc/libvirt/storage/autostart (symlink).




3com 3824 1Gb Managed Switch now in my possession

Got me a new piece of gear, a used (off ebay) 3com 3824 managed switch.  For my records and for yours, here are some reset instuctions for getting brand new setting setup if they weren't cleared prior to shipping off.


1) Get a null modem cable that has a DB9 on one end, and whatever suits you on the other.  I went with a DB9<->DB9 cable + null modem adapter + DB9<->USB.

2)Connect up cable to the serial console.

3)Install and fire up a terminal emulator of some sort.  For linux (RHEL, Fedora, openSUSE), grab minicom.  Configure it up to use 19200/8/N/1.  This should be printed on the front of the unit next to the serial port.

4)When you fire up, you should automatically be in the admin serial console screen at a lovely login.  Login with recover/recover as your login/password.  It will ask you to reset the unit to complete the password reset.  Do so by pulling the plug on it for a few moments and reconnecting it.  

5)Once its back up, you should have a reset prompt asking for the new password.  Your admin login will be admin/newpassword

6)To set the IP address info, enter the command 'protocol ip basicConfig'

7)Now we need to go and do a factory reset; enter 'system control initialize'


There you have it! 




Fixing gvfs automount permissions problems

The fix is to get the drives off of gvfs and into fstab.  For me it was a luxury that wasn't meant to be.  A half dozen USB disks of varying sizes all hooked up and mounted nicely.

Well to fstab it needed to be.  Here's how to do it nicely

1)Run "gnome-disks" and rename them if need be.  In my case I had several 500G Seagate and 1TB WD entries.  Make life easier on yourself if you haven't already.

2)Open up 2 terminals.  In one, run 'sudo gedit /etc/fstab' and in the other just 'sudo su -'

3)Use the second terminal to get the block ID information by running (need to be root) 'blkid /dev/drive'

4)Make your fstab look something similar (add), presuming the mountpoints you have figured out andyou are using ext4:


5) Unmount the drives if need be and issue a 'mount -a' command
