Custom system build for Ubuntu


I am considering assembling a Linux (Ubuntu 14.04) system to replace my
aging Sun Workstation/Server.  As this is my first attempt at builting a
system from scratch, I am seeking comments to hopefully avoid any obvious
mistakes.  I would be very interested in hearing from anyone who has used
these components regarding their compatibility or incompatibility with
Ubuntu, as well as more general comments should you believe that there are
better alternatives or issues of which I should be aware.

I plan to set up virtualization (probably using KVM) and run Ubuntu and
Windows 7.  The system will act as a mail and web server for a small LAN
and will be used for CAD, photo editing and software development.  Thanks
for any insights you can offer.

Configuration:

  * Cooler Master Cosmos II Case
  * Corsair HX850 Watt Power Supply
  * Asus Z9PE-D8 WS Motherboard (EEB Form Factor, C602 Chipset)
  * (2) Xeon E5-2630 v2 CPUs
  * (2) Dynatron R17 Fan Cooler
  * Nvidia Quadro K4000 GPU
  * 32 GB Crucial PC3-12800 EEC Registered RAM (CT2K16G3ERSLD4160B)
  * (2) Sandisk Extreme PRO 960 GB SSD (SDSSDXPS-960G) (Mirrored)
  * (2) Seagate 3TB SATA-III NAS Drives (ST3000VN000) (Mirrored)
  * Pioneer 16x BDR-209DBK Blu-Ray/CD/DVD Burner
  * Rosewill RDCR-11003 3.5" USB3 Flash Card Reader/Writer

Why is there no more adblock-plus package?

Hi,

Older versions of Ubuntu had a nice little adblock-plus package. 
Unfortunately it isn't available anymore, which means I have to install 
it manually for about 80 users.

Of course I can use Squid, but Adblock Plus had the advantage of having 
a per-site configuration. Sometimes users have to be able to temporarily 
disable Adblock.

Cheers,

Niki

cups is being a PIMA

Greetings;

Since apple has discontinued the cups mailing list, we don't have anyplace 
to ask cups related questions but on the distro's own lists.  So here 
goes. With a bit of venom:

I just spent the better part of an hour, and many many trips up and down 
the stairs to where my B&W laser, a Brother HL-2140 is located.  Trips up 
and down the stairs these almost 80 yo legs didn't appreciate a bit.

This printer, I know for a fact, can run out of paper and sit there 
patiently waiting for paper, hours/days/maybe even weeks if there is no 
power failure, for me to put more paper in it and it will take right off 
from where it was at and finish the currently hung print job. I've had it 
set to do so for the 3 years I've had this printer.

But some well informed genius, in a fairly recent cups update of the 10.04 
LTS tree, has seen fit to make cups disable the printer, making you go 
thru fire'y hoops canceling jobs to completely clean up the queue before a 
service cups restart will re-enable the printer. Doing a restart with jobs 
in the queue doesn't do it. It must start with a clean slate.  There was a 
time when a simple cups restart was sufficient, regardless of what was in 
the queue.

So: Where/What do I edit to restore the cupsd's ability to patiently wait 
on a printer that has run out of paper?

Thanks.

Cheers, Gene Heskett

Many thanks, Julian.
Greatly appreciated.

I set the value to zero and now feel VERY comfortable about it all.

Great stuff.

update failure

Hi, 

I'm running Mythbuntu 12.04 and the update manager has told me 
that, "New hardware support is available".  Clicking on install 
and upgrade does not have the desired effect.  What I get is, 
"Package dependencies can not be resolved", with the following 
details.  I have edited the white space to make it more obvious 
that the version numbers look OK.  

Not attempting to change to 14.04 (yet).  
Just using 12.04 LTS. 
12.04.1 -> 12.04.2 -> 12.04.3 -> 12.04.4 -> 12.04.5

The last step failed for no obvious reason.  My guess 
is that there is a version comparison algorithm that 
can not quite cope with the version designations actually 
used.  Some of them got longer rather than higher.  

Any thoughts?  Report a bug?  Against what?  

Edited cut'n'paste...  

The following packages have unmet dependencies:

libgl1-mesa-glx-lts-trusty:
        Depends:
        libglapi-mesa-lts-trusty
                (= 10.1.3-0ubuntu0.1~precise1) but
                   10.1.3-0ubuntu0.1~precise1 is to be installed

        Depends:

                (>= 2:1.4.99.1) but
                    2:1.4.99.1-0ubuntu2.2 is to be installed

                (>= 1:1.1) but

~/.gconf problem

Greetings all;

Can someone tell be what to do with /home/me/.gconf?

According to an ls -la:
drw-r-xr-x  4 gene gene   4096 2014-07-22 12:48 .gconf

I own the thing, and I ought to be able to do whatever I want with it, 
including copying a tree from a machine that gedit works on, to a machine 
it won't work on.

I was able to chmod it to 0777 which got rid of the no permission refusals 
to even cd into it, or do an ls -laR on the tree.
So now I may have gained access to this tree, what do I need to do to make 
gedit work in an "ssh -Y alias of FQDN" environment?

It does work if I run it from a console on that machine, but hangs in a 
loop, outputting this at about 3 second intervals from this machines ssh -
Y cli.

gene <at> lathe:~/.gconf/apps/gedit-2$ gedit
GConf Error: Failed to contact configuration server; some possible causes 
are that you need to enable TCP/IP networking for ORBit, or you have stale 
NFS locks due to a system crash. See http://projects.gnome.org/gconf/ for 
information. (Details -  1: Failed to get connection to session: Failed to 
connect to socket /tmp/dbus-c9qBvRFz9a: Connection refused)

The only thing that changes in each of these repeating error splats is the 
/tmp/dbus-hash_number.

That I can't check without physically going to the machine as /home is the 
only NFS share on these machines.  That I can fix, but why should I have 
to?  Call me puzzled.

Cheers, Gene Heskett

14.04: Trouble with RocketRaid eSATA card. Alternative driver available or return card?


 Dear All,

 I have difficulties getting the RocketRaid 622 eSATA Raid card from
 HighPoint working under Ubuntu 14.0 in a ProLiant Gen8 Microtower.

 Setup of rr62:

 I followed the instructions in the Ubuntu wiki at
     https://help.ubuntu.com/community/RocketRaid
 section on
     "Updated and simplified procedure for Ubuntu 13.04 or later"
 to build the v1.2 sources available from HighPoint's website.  These
 seem to be the latest drivers available at HighPoint.

 Build succeeded using the patch
    "rr62x-linux-src-v1.2-kernel-3.11v2.patch"
 found following links from that page (I think I found it that way)

 Build and installed the module using dkms, as described on the wiki
 page.

 The module failed to load with "out of memory", so I changed all
 "GPF_ATOMIC" allocations in the initialization to "GPF_KERNEL", which
 allows the kernel to suspend the allocation and try to free up some
 pages.

 Loading after system boot (and as such after loading ZoL) still fails,
 but the module rr62x now autoloads at boot time.

 Kernel currently in use is (uname -a)
 "Linux hpmicro 3.13.0-24-generic #46-Ubuntu SMP Thu Apr 10 19:11:08
 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux"

 Hardware:

 HP ProLiant Gen 8 Microtower server with 2x 8 GB ECC RAM (Kingston)

 Four internal spinning SATA disks in the four drive bays.  Not used
 for system files.  Part of a larger ZoL ZFS Pool.

 One internally installed USB thumb drive holding the 14.04 server
 install image

 One internally installed SSD holding the ext4 root filesystem "/" (no
 further "var" or "usr" partitions, everything under "/").  This SSD is
 connected to the SATA connector reserved for an optical drive and
 occupies the space meant for an optical drive.

 One eSATA port of the rr622 card is connected to a FanTec 4-bay SATA
 enclosure holding 2 more spinning SATA disks which are part of the
 same ZFS Pool as the four internal disks.  The FanTec uses a
 Port Multiplier to drive up to four disks over a single eSATA
 connection.

 Actual Problem:

 As soon as moderate traffic goes over the eSATA link, rr62x complains
 about port delays and goes into a reset / soft reset / reset / ...
 cycle until eventually declaring all disks behind the Port Multiplier
 as dead.

 While doing so, it partially locks up the system to the point the
 hpwdt watchdog seems to fire, causing a constant beeeeeep which only
 goes away by power cycling the box.  The system recovers once no more
 attempts are made to use the eSATA connected disks and all in-flight
 IO requests have terminated with error.

 Questions:

 Has someone managed to get the rr622 card working reliably under 14.04
 and kernel 3.13?

 If so, with which driver or options etc.?

 I bought this card because it advertises as "Linux compatible".  As
 this looks like not (any longer) being true, I consider sending it
 back for a refund.

 Can someone suggest a PCIe card with 2 (or more) eSATA ports that
 support Port Multipliers and that is actually supported under 14.04?
 I do not need any Raid functionality, I only need to connect a bunch
 of SATA disks mounted in FanTec 4-bay enclosures.

 Thanks for reading!
