HAProxy logging on RHEL7

How to configure RHEL7 rsyslog for haproxy logging.

Problem: The haproxy config (/etc/haproxy/haproxy.cfg) reports how to enable logs; however, this seems to be syslogd specific which is not what is running in RHEL7

Solution: enable logging via rsyslog configs:
Modify /etc/rsyslog.conf to include:

# Provides UDP syslog reception
$ModLoad imudp
$UDPServerRun 514
# Provides TCP syslog reception
$ModLoad imtcp $InputTCPServerRun 514

*note: maybe only UDP or maybe only TCP is needed.

Modify /etc/rsyslog.d/listen.conf

SYSLOGD_OPTIONS="-m 0 -r"
local2.* /var/log/haproxy.log

*note: this could just as easily be /etc/rsyslog.d/haproxy.conf, i chose the prior only because it pre-existed.

*note: local2 is the default in haproxy, but this could be changed if desired.

*note: the -r is required, the -m 0 is not, but meant to reduce junk. If it is looking up DNS and you don’t want, then add -x

Now sudo systemctl restart rsyslog and tail -f /var/log/haproxy.log to see the records.

Note: There are many and more complex settings, this is just a most basic configuration.

As always, good luck!

SAVE $$$ with TING

OMG! I am saving so much money with TING! My costs are HALF my AT&T bill!!!

TL;DR? $25 credit with my referral: https://z3oifh75bbn.ting.com/

I dropped AT&T wireless (AT&T Mobile) completely and you can too. Drop Verizon, Drop T-Mobile, Drop Sprint, Drop MetroPCS, Drop Boost, Drop Cricket, Drop everyone else.  Nobody is as affordable as Ting.

TING has the simplest mobile billing ever! – You pay $6 per phone flat-rate, and then you pay only for the services you use. You do NOT pay for more than you actually use. Every month is adjusted automatically.

For example, our typical month goes as follows: We have two phones ($6 + $6). We use less than 500 minutes talk time (+ $9); we use less than 1000 text messages (+ $5); we use less than 1GB of data (+ $16). This calculates to $42 dollars plus fees and taxes. Our monthly bill is typically $46.23 which is approximately HALF my previous AT&T bill.

This is my actual bill: Simple as simple could be!

Want to save money also? Please use my referral https://z3oifh75bbn.ting.com – You will receive a $25 credit to apply to a phone or service. You will not be disappointed with Ting!

Lost or Stolen Mobile Device Location Services (Find My Device)

Lost or Stolen Mobile Device Location
(Modern Devices 2014 2015 2016 2017 2018)

In the event of lost or stolen devices, it is best to have your device prepared ahead of time.

Below are the "native" ways to do, but I will also present two other free services afterward.  Generally your device has to be powered on and have connectivity.  Some services offer a last seen location.

Android

To prepare your Android device, install "Device Manager" from the Google Play Store. Login with your Google account and approve location sharing if necessary. You may need to turn on Settings->Location Access+GPS+WiFi. If you have multiple Android devices, this app will also help locate your other devices.

In the event of a lost or stolen device, visit https://www.google.com/android/devicemanager and login with your Google account that was used to setup the device. Device Manager allows you to locate, ring, lock or erase your device. (You may have to "Setup Lock & Erase" First.)

iOS

To prepare your iPhone or iPad, go to Settings->iCloud. Login if necessary (use your Apple account) and pan down to "Find my iPhone" (or iPad) and turn it on. Also turn on "Send Last Location". You may need to turn on Settings->Privacy->Location Services also.

In the event of a lost or stolen device, visit https://www.icloud.com/#find to locate your device.

3rd Party

Now although the above certainly work, I personally don't want to be limited to only this.

I also recommend both Prey (https://preyproject.com/) and Lookout (https://www.lookout.com/).

Prey is a free location/anti-theft app for up to three devices including laptop computers. If lost or stolen, visit https://panel.preyproject.com/app where you can locate, lock, erase, send an alert, or sound an alarm. Prey may also be able to access the front facing camera.

Lookout is a free antivirus, backup, and device-location app with additional paid backup features. Once installed and configured, visit https://www.lookout.com/d/missingDevice to locate, lock, erase, or sound an alarm.

Plan B (https://faq.lookout.com/categories/20504137-plan-b) offered by Lookout.com may also help you locate your Android device if you have not configured any previous location services.

Good luck!

Custom Mime File Type Icon in XFCE Thunar

I wanted to associate a custom icon for my old .PSP files in XFCE, but had no clue how.  Thanks to https://unix.stackexchange.com/questions/23776/how-to-change-a-file-type-icon-in-xfce-thunar, I was able to do it easily.

Firstly create a custom icon, then save it into ~/.local/share/icons/.  (Alternatively, with sudo/root access try /usr/share/icons/. For example, mine was ~/.local/share/icons/pspimage.png.

Then create a new mime xml in your user’s ~/.local/share/mime/packages/. For example, mine was ~/.local/share/mime/packages/pspimage.xml. (Alternatively, for system-wide, try /usr/share/mime/packages/.)

Which contained:

<?xml version="1.0"?>
<mime-info xmlns='http://www.freedesktop.org/standards/shared-mime-info'>
  <mime-type type="application/octet-stream">
    <comment>PaintShop Pro Image</comment>
    <glob pattern="*.psp"/>
    <glob pattern="*.pspimage"/>
    <generic-icon name="pspimage"/>
    <icon name="pspimage"/>
  </mime-type>
</mime-info>

Then simply update your system: (Alternatively, as sudo/root, perform same as below in /usr/share/mime/packages/.)
cd ~/.local/share/mime && update-mime-database $PWD

Refresh your Thunar view and viola.

2 Ways to Linux CommandLine Thesaurus Synonyms

[How to] Linux CommandLine Thesaurus | Linux CommandLine Synonyms

I wanted to use my linux commandline to lookup synonyms (thesaurus) recently but didn’t know how.

After some searching I was able to find 2 alternatives that worked very differently, yet helped me tremendously on each account.

Method 1 - DICT

sudo apt install dict dictd dict-gcide dict-moby-thesaurus
sudo systemctl enable dictd
sudo systemctl start dictd
dict --help # or try 'man dict'
#dict -d moby-thesaurus YOURWORDHERE
alias thes='dict -d moby-thesaurus'
thes engineer

Method 2 - WordNet

sudo apt install wordnet
man wn | grep -B1 synon
#wn YOURWORDHERE -syns#, where # is n, v, a, or r
#wn YOURWORDHERE -simsv
wn # or try 'man wn'
wn engineer -synsn | grep -v ^$   #grep just strips empty lines from output
wn engineer -synsv | grep -v ^$

Script for both:

#!/bin/sh
if [ "$1" = "" ] ; then
   echo "usage: $0 WORD"
fi
wn $1 -synsn | grep -v ^$
wn $1 -synsv | grep -v ^$
wn $1 -synsa | grep -v ^$
wn $1 -synsr | grep -v ^$
dict -d moby-thesaurus $1

[Solved] PulseAudio stopped working in Debian 9

[Solved] PulseAudio stopped working in Debian 9 Stretch on Dell Optiplex 9020

After some recent updates, unknown when and unknown why, PulseAudio stopped working properly. Sometimes it would work and sometimes not, it was the fight of all fights.

Multitudes of resources that failed to resolve only aggravated my situation. My final solution came from multiple sources, some of which i have already forgotten, but i will link some that helped.

Specifically to my Dell Optimplex with built-in Intel HD 4000 graphics, HDMI Audio was always a problem to the extreme. It always got in the way. If found a resource that spoke about making an NVidia HDMI work, but in actually this resource helped me disable it. Please refer to: https://www.linuxquestions.org/questions/linux-hardware-18/no-hdmi-audio-in-linux-819172/

When I performed the command aplay -l, I found my Intel HDMI Audio to be card 0. I created/modified my /etc/modprobe.d/sound.conf to contain options snd-hda-intel probe_mask=0xfff2 as per the post. Maybe that doesn’t even do anything. But then I chose the best thing ever. The post said to sudo rmmod snd_hda_intel then sudo modprobe snd_hda_intel, but screw that, i just sudo rmmod snd_hda_intel without reinserting it. Afterward aplay -l did not show card 0, hells yeah!

PulseAudio still caused me super rage mode, it just didn’t work as expected if it worked at all. i had to rm -rf ~/.config/pulse/ and rm ~/.asoundrc multiple times. Mostly the daemon would not start under my user account, but ran much better as root after the above “fix”.

So i decided, I need to run pulseaudio as root always (really this is called running under “system”). I found the command needed to be sudo pulseaudio --system --daemonize --disallow-exit. Warning: official documents say do not do this for security reasons, but F**K, it’s a pile of S**T and fails to work, so i’m doing it.

When I ran this, it seemed to work, but then would flake out. It seemed pulseaudio wanted to re-launch under my useraccount occasionally, so I eventually found to modify /etc/client.conf to include autospawn = no.  Of course  I had to sudo killall pulseaudio multiple times too.

Now everything seemed to work, so I proceeded to make it autostart at reboot this way. I ran sudo crontab -e and inserted @reboot pulseaudio --system --daemonize --disallow-exit. I rebooted and GLORY.

Additional Notes:
I should note that I had to verify my user/groups were in order too with sudo usermod -a -G pulse,pulse-access,audio $(whoami). I also did it for the user pulse but i really think that was overkill. Regardless attempting pulseaudio as user was still B******T. Also note, that modifying group memberships requires a reboot. (There are ways to avoid reboot, but reboot is wisest.)

Practically "Free" Landline service with ObiHai and Google voice (VOIP)

FREE LANDLINE PHONE - IT'S TRUE !!!

I have purged myself from paying for a traditional landline.

I can hardly believe that's it's been this long.  Since November of 2013, I have had practically free landline service by using Google Voice via an OBIHAI.com device over my Internet Service.  (Yes, I do pay separately for Internet.)  Google Voice calling is free nation-wide. (If you need to call overseas, they offer extremely low international rates.)

If I had retained my traditional phone service costing about $30 per month, I would have paid over $360+fees+taxes per year. However, I have only paid 80 cents per month for my optional e911 from Anveo.com, plus the initial cost of hardware.

How i did it:

I purchased the OBi200 from Amazon for less than $50.  You may also choose the Obi202, which is 2-port version. You should also purchase the replacement warranty 3rd party service for less than $5.  OBIHai Officially supports Google Voice. Also see the OBIHai+GoogleVoice Overview.



I then acquired a Google Voice phone number and configured my ObiHai to use it.  (Technically, I ported my existing number for a cost, but such is optional.  If you find you cannot port your landline number, you can circumvent the system by porting it to a mobile device SIM, then to Google -- This was a $30 and 5 day process for me -- again this is optional as I preferred to retain my existing number.)

My family has utilized "FREE" VOIP phone service for years now and it is of the same quality as any phone service from a traditional provider.  It works perfectly with my multi-phone cordless base-set much like this one.  Additionally, with Google Voice, I am able to receive voicemail recordings and missed call notifications direct to my Gmail.  I can also block numbers easily via web interface and use other awesome features such as having Calling Circles for filtering calls direct to voicemail.

Most telephony service providers are now only offer VOIP anyway.  With Google and OBiHai you can now remove the middle-man and have the same service without the $20-30 monthly costs associated with it.

Google Voice does NOT provide 911 service; however, Anveo.com provides me with e911 for a mere 80 cents per month.

Please consider using my Amazon affiliate Ad for the OBi200 above and optionally my Anveo.com referral code 7384061.

For a little more detail on the ObiHai device, see this nice article: https://www.geekzone.co.nz/sbiddle/8736

DO NOT BUY OBi300 nor OBi302, they DO NOT SUPPORT GOOGLE VOICE!

Buy OBi200 or OBi202, or research other products.
