CentOS 6.0 OpenGTS 2.3.8 install and demo setup howto

This is the quick install and setup for OpenGTS and CentOS 6.0.  OpenGTS is a general GPS tracking software for many types of devices. There is also a commercial version.
There are some details missing, but the jist of what needs to happen is here.

*Please keep in mind that I live VERY near St. Louis and was writing this during the World Series Championship game 6 and game 7! I've been distracted to say the least ;)

OpenGTS Config manual is the REAL source for what needs to be done, but here are the steps for CentOS 6.0 with a little strategy difference (I wanted to use the CentOS provided version of most everything).

If you want to use the "real" java SDK, fine, download it from HERE and change the rest of the java install accordingly:

yum install ant mysql-connector-java java-1.6.0-openjdk tomcat6 apache-tomcat-apis httpd classpathx-mail
cd /opt
wget "http://sourceforge.net/projects/opengts/files/server-base/2.3.8/OpenGTS_2.3.8.zip/download"
unzip OpenGTS_2.3.8.zip
ln -s OpenGTS_2.3.8 OpenGTS

Create environment file

cat >> /etc/profile.d/opengts.sh << EOF
#The Java JDK (NOT the JRE) installation directory.
#export JAVA_HOME=/usr/java/latest
export JAVA_HOME=/usr/lib/jvm/java-1.6.0-openjdk-1.6.0.0.x86_64
#The Apache Ant installation directory.
#export ANT_HOME=/usr/lib64/gcj/ant
#The Apache Tomcat installation directory.
export CATALINA_HOME=/usr/share/tomcat6
#The OpenGTS installation directory.
export GTS_HOME=/opt/OpenGTS
EOF
. /etc/profile.d/opengts.sh

If you don't want to use the "classpathx-mail" javamail.jar you can download the mail.jar from Oracle or  here:

unzip javamail1_4_4.zip
cp -p ~/javamail-1.4.4/mail.jar $JAVA_HOME/jre/lib/ext/

OR just use the one installed:

ln -s /usr/share/java/javamail.jar $JAVA_HOME/jre/lib/ext/

Here are a couple of symlinks that help out:

mkdir /usr/share/tomcat6/common/lib
cd /usr/share/tomcat6/common/lib
ln -s /usr/share/java/tomcat6-servlet-2.5-api-6.0.24.jar servlet-api.jar
ln -s /usr/share/java/mysql-connector-java-5.1.12.jar $JAVA_HOME/jre/lib/ext/

The real meat of the install of the java stuff:

cd $GTS_HOME
ant all
ant track.war
ant track.deploy

A couple of housekeeping commands to silence warnings/errors before running the checkInstall.sh:

ln -s $JAVA_HOME java
ln -s $CATALINA_HOME tomcat
ln -s $GTS_HOME gts
$GTS_HOME/bin/checkInstall.sh

Correct issue noted from the checkinstall script.

Initialize the database and get the demo stuff up and going:

service mysqld restart
service tomcat6 restart
echo "create database demo;"|mysql
$GTS_HOME/bin/initdb.sh -rootUser=root -rootPass=
$GTS_HOME/bin/admin.pl  Account -account=demo -nopass -create
$GTS_HOME/bin/admin.pl  Device -account=demo -device=demo  -create
$GTS_HOME/bin/admin.pl  Device -account=demo -device=demo2 -create
$GTS_HOME/bin/dbAdmin.pl   -load=EventData -dir=./sampleData

Look at $GTS_HOME/logs/TrackWar.log or /var/log/tomcat6/catalina.2011-10-26.log for issues.

Next part will be connecting a real test client to this server... coming soon!

CentOS 6.x updated wine-1.3.29 install howto

Stable is good! That's why I like the CentOS/SL/RHEL distrobutions. But sometimes you need to kick it up a notch and go more recent with specific packages. It might be an office suite update or a Xen update or even a PHP update; it doesn't matter, you just need some part that is, well, more recent. This time it's wine. And, instead of version wine-1.2 stable something, you get to most recent and kick-ass version 1.3 something. I can say that the wine-1.3 is much better at handling the oddities of running  the most recent Google Windows Picasa version. Let's face it, the Linux version 3.0 is OK, but WAYYYY dated. Besides, the face recognition is much better in Picasa 3.8. Enough fluff; down to business. Start off with some good information from the CentOS RPMForge link
and make sure to set up either priorities or ProtectBase. Get familiar with RPMForge/Repoforge. Then install it the important repository:
(32bit)

rpm -ihv http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.2-2.el6.rf.i686.rpm

(64bit)

rpm -ihv http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.2-2.el6.rf.x86_64.rpm

By the way, this wine upgrade also works with CentOS/SL/RHEL version 5.x. Just substitute "el5" for"el6" above.

Get rid of the old:

yum remove wine\*

In with the new:

yum install wine --disablerep=\* --enablerepo=rpmforge-testing

All done! Time to pay attention to the St. Louis Cardinals as they play for the World Series World Series against Texas ;)

CentOS 6.x Mythtv 0.24 plus Hauppauge PVR-500 setup hotwo

Let me start by stating that getting this setup to be functional was a frustrating experience. Mostly due to my lack of Mythtv setup experience. It's not to say that I have not been using Mythtv for a very long time. It's more along the lines that I run the boxes for sooooo long without issue and therefore don't have to deal with setup very often. The box I'm replacing was a venerable CentOS 5 setup with a single Hauppauge PVR-250. The other issue is that I introduced some new-to-me equipment (the PVR-500) and most found documentation did not directly pertain to the mythtv-0.24 version.

Basic CentOS 6.0 32bit is documented in a previous post. This will be more about the setup of the Hauppauge PVR-500 since that was really the only problem.

There is some some information in the Mythtv wiki that is helpful.

Please keep in mind that my main intent is to show the PVR-500 setup and not all
the easy other stuff.

Step 1: run mythtvsetup
Step 2: select "Capture cards" -> "New capture card"

Step 3: from "Card type:" select "H.264 encoder card (HD-PVR)" then "Finish"

Step 4: select "New capture card" -> "Card type:" select "H.264 encoder card (HD-PVR)" again. This time change "Video device:" to "/dev/video1" then "Finish"

Step 5: add your "Video source" and "Input connections" and follow any other instructions you have ;)

Error messages I had while trying to get the PVR-500 setup correctly:
snd_pcm_open_noupdate unknown pcm default
Error: Failed to open audio device ALSA:default
Encountered problems running /usr/bin/mythpreviewgen

Note: vlc error:

*** glibc detected *** vlc: free(): invalid pointer:

 Solution was simple for this 32bit install, as root:
mv /usr/lib/vlc/plugins/meta_engine/libtaglib_plugin.so ~/libtaglib_plugin.so-vlc-issue

Google Music Manager native Linux client install and review

To Google's credit they have quickly moved to a native Linux client with their beta Music Manager, The "google-musicmanager-beta-1.0.18.6104-0.i386" was built on September 14 and made available on September 24 2011. The initial Music Manager was built on wine like some other notable Google products (like Picasa). The Linux version of the Music Manager is now native! And since there is no bundled wine the install size is a very modest 9.5MBish.

I am running this test on CentOS 6.0(CR). Other choices for downloads is available from HERE or by going to your "ADD MUSIC" option toward the top right of the music.google.com screen after Google login. Google has downloads for Debian/Ubuntu and for Fedora/openSUSE in both 32bit and 64bit:

As root install your download. For my CentOS box I did:

yum install google-musicmanager-beta-1.0.18.6104-0.i386

 You can run the program from the command line by just typing  at your GUI prompt:

google-musicmanager

To run the Linux Google Music Manager from the Gnome desktop, just select "Applications" -> "Internet" -> "Google Music Manager". You will be greeted with this start sequence:

Here is a screenshot of the "About" for this installed version:

Here is a screenshot of the Gnome panel view of the running Music Manager:

Firefox seems well supported for Google Music when you have Flash installed:

CentOS 6.x Mythtv 0.24 install and setup hotwo

This is originally created with CentOS 6.0. Prior to the release of CentOS 6.1, I strongly urge all admin's to use the CentOS 6.0 CR Updates to enhance the security of your system. Also, my CentOS Mythtv server was a  "Desktop" install option for this example. I have cable TV and have used both the Hauppauge PVR-250 and now the Hauppauge PVR-500 since my needs are basic.

UPDATE: I have the PVR-500 CentOS 6 setup info with pictures for mythtv 0.24 now.

Get the security related updates first:

rpm -ihv /home/pj/Downloads/centos-release-cr-6-0.el6.centos.i686.rpm
yum update

Install both EPEL and RPMFORGE repositories and please remember to also install *AND* setup either priorities or protectbase yum plugins.

rpm -ihv http://dl.atrpms.net/all/atrpms-repo-6-4.el6.i686.rpm
rpm -ihv http://download.fedora.redhat.com/pub/epel/6/i386/epel-release-6-5.noarch.rpm
yum install yum-plugin-priorities

Do these error messages look familiar?

Clean out the older/problem bits:

yum remove qt-x11 qt phonon perl-XML-SAX-Base

Install the initial problem packages:

yum install qt47 qt47-x11 qt47-webkit qt47-mysql --enablerepo=atrpms-testing

The big download and install:

yum install mythtv --enablerepo=atrpms-testing --exclude=perl-XML-SAX-Base

Make sure mysqld and mythbackend on going to try and start on boot

chkconfig mythbackend on mysqld on

You really need to read through the mythtv-HOWTO or even Installing MythTV on RHEL/CentOS

I'm migrating from CentOS 5.7 -> 6.0 following normal backup and restore steps:

service mysqld start
mysql < /usr/share/doc/mythtv-docs-0.24.1/database/mc.sql

A new simple no-security-just-get-it-running setup could include:

echo 'grant all on mythconverg.* to mythtv@"%" identified by "mythtv";' |mysql mythconverg
echo 'flush privileges;'|mysql mythconverg
mythtv-setupp

Again, you really need to read through the mythtv-HOWTO or even Installing MythTV on RHEL/CentOS for your specific tuner card.

Dell printer firmware update stupidity and howto

Not sure why Dell is taking recent steps backwards with regard to Linux support, but clearly it is. The recent BIOS update issues have given way to printer update utilities that are not Linux install friendly. The most recent example is the otherwise decent Dell 2555dn MFP. The previous A02 version of the firmware (DELL_2355DN-MONO-LASER-MFP_A02_R302331.exe) was just a self-extracting zip file. So a simple

unzip DELL_2355DN-MONO-LASER-MFP_A02_R302331.exe

would provide me with the needed "*.hd" (Dell2355dn_A02_v2.70.03.06.hd in this case) firmware file to load via the update firmware web page.
Now Dell seems to add in their install/extractor utility like the general Windows driver files have... and it takes some extra effort.

My current system/admin setup is based on CentOS 6.x but any recent distro will likely be very close. I'm going to assume that you have already downloaded the file and you are at a command/terminal prompt.

1. Install wine as root

yum install wine cabextract

2. As a normal user get winetricks and install "vcrun6"

wget http://winetricks.org/winetricks
chmod +x winetricks
./winetricks vcrun6

3. As a normal user run the installer like and just exit after the GUI comes up

wine Dell2355dn_A03_2.70.03.08.exe

4. After you should be able to find the needed *.hd file in "~/.wine/drive_c/users/YOUR_USERNAME/Temp/". For this example, it was "~/.wine/drive_c/users/pj/Temp/Dell2355dn_A03_2.70.03.08.hd"

Possible error messages:
If you don't have the VBRUN 6 installed (vcrun6) you will get an error like:
err:module:import_dll Library MFC42.DLL (which is needed by L BLAHBLAH) not found
err:module:LdrInitializeThunk Main exe initialization for L BLAHBLAH failed, status c0000135

CentOS 6 lpadmin generic postscript printer addition

It really took a while for me to figure out how to add printers via the command line using lpadmin on CentOS 6. So, this information also will apply to newer Fedora users as well as RHEL 6 users:

For generic LPD/LPR Postscript print server:

lpadmin -p printer_name -m drv:///sample.drv/generic.ppd -v lpd://your_print_server/raw1 -D "Your printer description" -L "Your printer location" -o printer-error-policy=retry-job -o printer-is-shared=false -E

For generic LPD/LPR PCL print server:
lpadmin -p printer_name -m drv:///sample.drv/generpcl.ppd -v lpd://your_print_server/raw1 -D "Your printer description" -L "Your printer location" -o printer-error-policy=retry-job -o printer-is-shared=false -E

For Jetdirect/RAW print servers

lpadmin -p printer_name -m drv:///sample.drv/generic.ppd -v socket://your_print_server:9100 -D "Your printer description" -L "Your printer location" -o printer-error-policy=retry-job -o printer-is-shared=false -E

The new part is "drv:///sample.drv/generic.ppd" as the model instead of "postscript.ppd.gz" or similar from the past. This seems to trigger a ppd file build from the script/file of "/usr/share/cups/drv/sample.drv" as part of the cups package.

Notes:

I don't like the default option of not retrying failed jobs. It's a dumb default IMHO! The "-o printer-error-policy=retry-job" is a better choice.

I also tend to turn off sharing as a general rule. You may want it on, however. The "-o printer-is-shared=false" turns off printer sharing.

The Jetdirect/RAW printer socket can change for print servers with multiple ports. First port is 9100, second is 9101 etc. The same kinda process exists for the LPD/LPR print server where "raw1" will increment for printer port as a generic rule.
