Make UBNT device use a single polarity.

by Jim Bouse 16. December 2013 11:36

FYI in /tmp/system.cfg (configuration file):

radio.1.txchainmask=[bit mask]
radio.1.rxchainmask=[bit mask]

Where bit mask means which chain/chains to enable:

1(0bit) - chain0

2(1bit) - chain1

4(2bit) - chain2

So you can make combinations like 1 and 4 = 5, means chain0 and chain2 enabled. And so on.

NOTE: Chains are HW specif, not all have all chains or the same chains.

I guess my sample will help to make live easier and avoid custom scripts to be installed.

AC1 to AC2 GPS Coordinate Pusher

by Jim Bouse 13. August 2013 16:37

Ok... Since it looks like UBNT isn't excited about pulling data from AC1 into AC2, I whipped up a python script that copies the GPS coordinates from AC1 to the device so that it can be used in AC2.


Don't say I didn't warn you.

That said, I have run it against my network and it just caused breif outages while devices rebooted.

# AC1 -> AC2 Coordinate Pusher 1.0
# Jim Bouse
# 8/13/2013
# jim@mobileitpro.com
# This script runs on Python 3.3.2 on Windows.
# I have not tested against any other OS or version
# This script may destroy your network.
# This script may destroy your network.
# This script may destroy your network.
# I really mean it.  If this script blows your network up, 
# I'm sorry but I did warn you.
# The purpose of this script is to query AirControl v1 and populate
# the coordinates from AC1 into the config file in the devices.
# When the coordinates are in the config file, AirControl v2 properly
# places the device after discovery.
# NOTE: <------ READ THIS !!!
# This script reboots the devices after the file change.
# This means you will lose connection and it will be a problem if you # do it during a busy time.
# GOOD NEWS is that it only does it on the devices that need it.
# BAD NEWS is that it will have to be run a few times to get all the
# devices in your org,
# because if it reboots an AP, the clients will not be able to be
# connected to until the next pass.
# Instructions: Place this script and plink into the same directory.
# Open a command prompt and CD to the directory.
# Run this file.

Formatting MSSQL (TSQL) Date Columns

by Jim Bouse 28. December 2012 08:18

I often need to format a date column from SQL into something nicer.  The code below does that.

CAST(DATEPART(m, DateCol) AS varchar(2)) +
'/' +
CAST(DATEPART(d, DateCol) AS varchar(2)) +
'/' +
CAST(DATEPART(year, DateCol) AS varchar(4)) +
' ' + 
CAST(datepart(HH, DateCol) AS VARCHAR(2)), 2) ELSE RIGHT(REPLICATE('', 2) +
CAST(datepart(HH, dateadd(HH, - 12, DateCol)) AS VARCHAR(2)), 2) END + 
':' + 
CAST(DATEPART(n, DateCol) AS VARCHAR(2)), 2) + 
':' + 
RIGHT(REPLICATE('0', 2) + CAST(DATEPART(ss, DateCol) AS VARCHAR(2)), 2) + 
' ' + 
AS FormattedDate

AirOS 5.5.2 for UniFi

by Jim Bouse 3. December 2012 13:41

From time to time, I install UniFi access points for customers.  These customers normally do not need a controller and just want a nice looking AP.  NVX from the UBNT forums put together the firmware needed to convert the UniFi to a standard UBNT radio.

Here is the original post: http://forum.ubnt.com/showpost.php?p=389380

FreshBooks and Mikrotik Automatic Non-Payment Script

by Jim Bouse 9. October 2012 11:12

I have a WISP that has more customers that I would like to keep up with.  Most of the time is spent chasing down late payments.

I wrote the following combination of files to handle automating handling of Non-Payment customers.


  • Web server on a public IP address.
  • Domain Name.
  • FreshBooks account.
  • Simple Queue with a name EXACTLY matching the Last Name, First Name of the customer from FreshBooks.
  • Mikrotik Router with API access enabled.


  • In the Readme.txt



Zip File (v1.0)

From the Readme.txt:

Mikrotik Freshbooks Intergration Script v1.0

Jim Bouse
October 9, 2012

License: None... Feel free to use, modify, butcher, whatever, this code. I ask that if you add features, you send me a copy.

Plug: I own and operate an WISP that uses Ubiquiti and Mikrotik equipment. I also do consulting work and onsite assistance.


I needed to automatically block customers with overdue invoices. This is what I came up with.


config.php <-- all PHP variables set here
create_callback.php <-- creates callbacks on FreshBooks.com
email.php <-- queries FreshBooks for customers matching names in Simple Queues
index.php <-- responds to callback requests from FreshBooks.com
AND is the page the customer is redirected to on non-payment.
Readme.txt <-- This file.
routeros_api.class.php <-- API class downloaded from http://wiki.mikrotik.com/wiki/API_PHP_class


1. Setup a sub-domain for your files to reside on. (http://payments.example.com)
Place all files from zip there.

2. (OPTIONAL) Enable port 800 on web server.
This is needed if you don't have a dedicated IP for your payment server.
Also edit the PaymentServerPort to match in the Mikrotik Script at the bottom.

3. Setup the web server to redirect all 404 errors to index.php

4. Verify that the webserver can write to the directory of these files.
This is used for logging.

5. Modify config.php to match your environment.

6. Add the "Late Payment Fees" add-on in FreshBooks

7. Modify the default behavior of the late payment email to send a notice on day 20
and another notice on day 30. (FreshBooks ->Settings -> Emails)

8. Use create_callback.php to create the following Invoice "Past Due 2" and "Payment Create"

9. Run The script at the bottom on each of your Mikrotiks

Currently, the index.php script only responds to:


You can use the existing code as an example to create more.
Reminder: If you add new features, please send me the code so I can update the files for others.


Mikrotik Script:

:global PaymentServerIP "XXX.XXX.XXX.XXX"
:global PaymentServerPort "80"

/ip firewall nat add action=dst-nat chain=dstnat comment="Redirect Non-Payment HTTP"\
port=80 protocol=tcp src-address-list=NonPayment to-addresses=$PaymentServerIP\
/ip firewall filter add chain=forward comment="Allow Non-Payment HTTPS to FreshBooks"\
dst-port=443 protocol=tcp src-address-list=NonPayment
/ip firewall filter add chain=forward comment="Allow Non-Payment HTTP to Payment Server"\
dst-address=$PaymentServerIP port=800 protocol=tcp src-address-list=NonPayment
/ip firewall filter add chain=forward comment="Allow DNS" port=53 protocol=udp
/ip firewall filter add chain=forward comment="Allow DNS" port=53 protocol=tcp
/ip firewall filter add action=drop chain=forward comment="Drop Non-Payment tcp traffic"\
protocol=tcp src-address-list=NonPayment
/ip firewall filter add action=drop chain=forward comment="Drop Non-Payment udp traffic"\
protocol=udp src-address-list=NonPayment
:put "Done"

Set Simple Queue Burst Rates

by Jim Bouse 30. September 2012 19:56

I have a Mikrotik router as my bandwidth limiter for my ISP.  I use Simple Queues for each IP to assign them to a speed.  I recently decided to be nice and add bursting to the plans.  I decided that the customers would get 2X their purchased speed for 16 seconds (a standard time window).  Since I had about 100 IPs and Simple Queues, I defanately did not want to manually add bursting to my Simple Queues.  I wrote the following script.  It will loop through all your simple queues and add the 2X burst amount.

You can download the .txt here in case the formatting gets screwed up. - setSimpleQueueBurst.txt (1.46 kb)

:local rate
:local inboundrate
:local outboundrate
:local inboundburstrate
:local outboundburstrate
:local inboundburstthreshold
:local outboundburstthreshold
:local ip
/queue simple
:foreach i in=[find] do={
  :set ip [get $i target-addresses]
  :set rate [get $i max-limit]
  :set inboundrate [:pick $rate ([:find $rate "/"]+1) 999 ]
  :if ([:find [:tostr $inboundrate] "k" ] > 0) do={
    :set inboundrate ([:pick $inboundrate 0 [:find [:tostr $inboundrate] "k" ]]*1000)
  :if ([:find [:tostr $inboundrate] "M" ] > 0) do={
    :set inboundrate ([:pick $inboundrate 0 [:find [:tostr $inboundrate] "M" ]]*1000000)
  :set outboundrate [:pick $rate 0 ([:find $rate "/"]+1)]
  :if ([:find [:tostr $outboundrate] "k" ] > 0) do={
    :set outboundrate ([:pick $outboundrate 0 [:find [:tostr $outboundrate] "k" ]]*1000)
  :if ([:find [:tostr $outboundrate] "M" ] > 0) do={
    :set outboundrate ([:pick $outboundrate 0 [:find [:tostr $outboundrate] "M" ]]*1000000)
  :set inboundburstrate ($inboundrate*2)
  :set outboundburstrate ($outboundrate*2)
  :set outboundburstthreshold ($outboundrate*2)
  :set inboundburstthreshold ($inboundrate*2)
  :set inboundrate ($inboundrate/5)
  :set outboundrate ($outboundrate/5)
  set $i limit-at="$outboundrate/$inboundrate" burst-time="16s/16s" burst-threshold="$outboundburstthreshold/$inboundburstthreshold" burst-limit="$outboundburstrate/$inboundburstrate"
  :put "Set $ip simple queue burst."

Low Cost Outdoor UPS

by Jim Bouse 30. July 2012 16:24

I own a small WISP and need an UPS in a small enclosure at the bottom of my towers to provide temporary power for when the grid drops for a few minutes/hours.

This is often coupled with a multi-port POE injector from Wifi-Soft and a router for a WISP tower location.

This comes to $387 for an outdoor UPS with a run time of about 8 hours without power for 2 - 8 watt radios and a RouterBoard.

Here is a similar version of what I have described.
