Email bounce back Help

From: DJ Smith 
------------------------------------------------------
Well everyone, here's my 1st plead for assistance. 

We are running our own email server w/ Iredmail on a Debian box. Everything has been going good up till this 1 bounce back from a client. 

The only error they have sent me is this:
IOException during delivery. class: java.net.UnknownHostException

I have been through all our logs & I can not even see where their server even made or attempted a connection w/ ours. This leads me to believe that there's a middle man that is causing the problem. But it could be our server & I'm just simply overlooking something. 

So, I was hoping that 1 of you may have come across this error somewhere before.

Question on runlevel philosophy across distros

From: Rod-Lists 
------------------------------------------------------
If I may interupt todays Tn. vs. Ala. arguement, I've noticed different distros use different runlevel philosophies.
http://www.linux.com/news/enterprise/systems-management/8116-an-introduction-to-services-runlevels-and-rcd-scripts
I was wondering if the Debian/Ubuntu Sysadmins ever tighten up their run levels to be more tight like slack or red hat?

Useless and meaningless rant about my hate for Linux Mint...

From: kitepilot@kitepilot.com
------------------------------------------------------
I hate Unity too...
And/or the M$-like bloated KDE. 

Because my long hated (and mostly reliable) Linux Mint went out of support, 
I decided to go with what I hate the least: Xubuntu. 

But I could not burn the DVD, so I installed it on VirtualBox, transferred 
the system to my real box, fixed up the MBR and booted my shinny new 
Xubuntu.
No sound...
Darn... 

After fiddling with it for a day I decided: screw it, I'll go Debian Xfce.
So I got my trusty net-install CD and...
It said that it needed 'proprietary firmware' from Realtek, but WAIT!
It also said that I could install from the 'proprietary firmware DVD'! 

Which (of course) I could not burn either...
So I installed it on VirtualBox, transferred the system to my real box, 
fixed up the MBR and booted my shinny new Debian!  :-)
No sound...
And not second monitor...
Darn...   :( 

After fiddling with it for a day I decided: screw it, Mint worked before, I 
may as well give it a F$%#ING try (I *NEED* a box!)...
Of course I could not burn the DVD!!!!
So I installed it on VirtualBox, transferred the system to my real box, 
fixed up the MBR and booted my shinny new Mint 17 Xfce. 

And now everything works!
But I am hard headed and now I am facing years (I installed LTS) of hating 
MINT!!!! 

Grrrrrrrrr... 

3 wasted days later, and with a fully functional system that I hate, I am 
seriously considering to end it all and hang myself from a pumpkin tree...
I warned you that it was a useless and meaningless rant!
So there...

Pretend you are designing your dream home (or perhaps are remodeling

service anyway), what would you put in?

Audio/Video/Network/Automation/Alarm/Security/Camera/Paging

Rack full of Linux servers/VMs goes without saying, so we're on-topic.
:)  I've already decided on multiple CAT-6A pulls through-out the
house.  I have been impressed enough with Unifi that I will be using
their wireless, controlled by a Debian VM.  I know some of you have
some awesome ideas.  Feel free to unicast if you don't want to share
on the public forum, but I would enjoy hearing those ideas.

I'm baaaaaaack!

From: Ed King 
------------------------------------------------------
Got bumped off the list back in mid May due to "too many bounces".    Been checking chugalug.org webpage occasionally for any job announcements or hardware sells/freebies ;-)

I stayed unsubbed for awhile (and missed Hack-a-nooga too) because I needed to focus on our latest and biggest client rollout, which went "live" on 6/2/2014.    To "save money" we switched hardware platforms a few weeks before rollout (went from $800 kids-toy netbooks to $300 Dell Venue tablets), but the software platform stayed the same (albeit with some custom mods for the new client):    lamp stack (linux/apache/php/mysql) on qemu.    Why are we running in a vm/emulator?  Well its a long story but a previous 3rd party vendor wrote our field software.  This 3rd party vendor required Windows netbooks.  Their software was slow and flakey (as you'd expect from dot-net) so we ditched them and rewrote the field software in-house (like we wanted to do in the first place, and we did it in less than half the time, and still had more features and flexibility!).    But... we couldn't just throw out twenty $800 netbooks, so we leveraged that hardware "investment"
 by using qemu to run our lampp stack, thinking that it would also be portable if we ever moved to android (does anyone know of a qemu package for android that doesn't SUCK?)

Back-end:   For "security" this client did not want their data on the same server as our other clients, so I set up a new Debian server just for them.  HTTPS and automated sftp file transfers. 

Well now that this new client is up 'n running, I figured it was time for me to re-sub, so...  I'm back.  This new client is our biggest client to-date, and has doubled the amount of inspectors in the field (and doubled the data collection too...  thank goodness we solved that mysql lock problem we used to have).   Things are running smoothly!   I dare say that the support calls have somehow decreased (oh great, now I've jinxed us).    

Props to our little I.T. team:    Danny "dj" Smith Jada "coldfish" Case, and Master Ed :)









If you love SPARC, Debian could use you.

From: Rod 
------------------------------------------------------


http://www.linuxplanet.com/news/linux-top-3-debian-dumps-sparc-ubuntu-takes-over-linux-3.13-and-the-core-infrastructure-initiative.html

---------------------------------------------------
1) Debian Dumps SPARC for Jessie
While x86 has long been a primary server target of Linux, there are many  
other architectures out there too. One of them is Sun/Oracle's SPARC  
platform, which usually is often thought off as being only about Solaris  
Unix.

Debian had been providing support for its Linux distribution running on  
SPARC since March of 1999, but that is now over for new releases. On April  
26, Debian developer Phillip Kern announced that SPARC support had been  
removed from the Debian-testing branch due to a lack porter commitments as  
well as stability issues. Debian testing is the branch that will lead to  
the Jessie release at some point in 2014.
SPARC isn't entirely out of the Debian landscape though.

"The fate of SPARC in unstable has not been decided yet," Kern wrote. "It  
might get removed unless people commit to working on it."

old nVidia card drivers

From: Unkmar 
------------------------------------------------------
Ugh, in short.  Don't use the NV44 GeForce 6200 cards for anything more
than extremely low end graphics.  As in, testing or terminal only.

Summary: For me, nVidia cards have historically been pretty easy to
configure. Enter the nVidia GeForce 6200. It is a pain to get resolutions
above 640x480 using the nVidia binary drivers.  (Got a chant while dancing
in a proper elliptical style orbit around two fires without spilling you
beer.)  Seriously, it isn't that hard as long as you know to use the 5th or
is this the 6th method of configuring video settings? Because the first 4
or 5 don't quite get you there.  Some of those that don't work, and aren't
necessary and simply slow you down. I did get it to work and minecraft is
barely playable.  I think the key component was to generate a fresh
xorg.conf from which to start, using the command sudo X -configure.  After
that, nvidia-settings could see the modes above 640x480.

I'm running Debian and installed a new/old video card.  New as in just
purchased, old as in old Chipset. NVIDIA Corporation NV44 [GeForce 6200
TurboCache(TM)] (rev a1).  The card was purchased for several reasons.
Low end, inexpensive, passive cooling, stability.
Good for testing that the malfunction is somewhere other than a possibly
burned out video card without spending a C-note.
End result, my video card is not the problem. :(

Anyhow, back to drivers.  The card installs find. the nouvoue. 

All Packages Needed For FreedomBox Now In Debian

FYI:Linux and Software Defined Radio

From: Rod 
------------------------------------------------------
Been during research lately into linux and ham radio support.
There have been more than few good linux distros with a ham focus over the  
years.
At least two puppies, a few ubuntu respins, etc.

Just found Kali Linux which seems to be picking were up Backtrack Linux  
left off.
Kali Linux has an SDR metapackage that is worth looking into.
It includes their own fork of Debian's gnuradio which updates to the  
latests sources. As well as GQRX which support several USB SDR dongles.
Including a $20 TV dongle that can be used as a broad spectrum scanner  
that can be used for all kinds of cool stuff.
http://www.rtl-sdr.com/about-rtl-sdr/

While Kali Linux should be in any serious linux users toolkit, I'm not  
sure if a distro that runs as root by default is the best choice for some  
of my fellow hams. Especially the many who are xp refugees mourning the  
loss of their dead os. Though it has some good ideas for the start of a  
new HAM Shack OS.

Question for the mint crowd.

From: Rod 
------------------------------------------------------
Been reading up on debian mint. Ubuntu based or Debian what does mint  
bring to the table?
Mate or gnome II is not an issue as I'll do straight Openbox.
In other words why base a distro on Mint instead of going one of its base  
distros?

LaTeX copy and pasting from pdf output

From: "Robert A. Kelly III" 
------------------------------------------------------
 When I generate PDF from a LaTeX source file with pdflatex on Debian, I
run into several issues when copy and pasting from the PDF.

1. Double quotes show up strangely, or not at all. When I copy and
pasted on my system, the quotes are simply missing. When I sent it to
someone else and they copy and pasted and sent edits back in a docx
file, they had \ and " for the double quotes.

2. Indentation is lost, which means paragraphs are not properly delineated.

3. Line breaks are preserved, which is not desirable if you are pasting
into a context where you want the lines neatly rewrapped.

4. Automatic hyphenation is preserved, which is really undesirable if it
gets rewrapped when you copy and paste.

5. Page numbers are copied and pasted with the the text, which is also
frequently undesirable.

If anyone knows how to change any of these things in the PDF output, I
would appreciate it. Ideally, I would like to be able to copy and paste
from the PDF and have all of the characters show up in a usable form,
even if they are ascii equivalents, preserve indentation, but omit line
breaks, automatic hyphenation, and page numbers.

Has anyone used landscape to manage servers?

From: Rod

I was wondering what your thoughts on it were.
It might be a reason to deploy Ubuntu over Debian if your handling large  
scale server footprint.

elementaryos - Linux Distro?

From: Mike Harrison 
------------------------------------------------------

http://elementaryos.org/

Anyone tried this yet? It's getting some press,

Looks like another Debian/Ubuntu 12.04 remix with a pretty desktop
and light basic requirements.

They seem to be stretching my concepts of some words in their marketing, 
but seem to have an attractive window manager (Gala).

I was considering installing on a junk machine this weekend just to play.

Server Linux Distros

From: Mike Harrison 
------------------------------------------------------
Dave:
> Glad to see that my decision to leave RH with 7.3 is still a good one.

I'm having to do it for some contractual issues, and in one case because 
the Ubuntu world went to a kernel that does not easily support the 
hardware in place, and upgrading the hardware was not a good option right 
now.

I'm planning on trying a straight Debian Server next.
