Ubiquiti Unifi Notes & Odd methods of acquiring Info

1- Odd method to acquire total number of active WiFi Clients

Bash script to acquire some info via UniFi controller like active number of WiFi clients connected with different UniFi AP LR in the company.

#!/bin/bash
# Script to query active clients by curl from unifi controller

# 2nd-January-2017
#set -x
# UniFi Controller IP and Port
IP="10.0.0.1"
PORT="8443"
COOKIE="/tmp/cookies.txt"
TMP_HOLDER="/tmp/$IP.active.wifi.clients.txt"
# pattern to match to count active clients using string matching
PATTERN="hostname"

# First Login to controller via CURL
curl -s "https://$IP:$PORT/api/login" --data-binary '{"username":"admin","password":"CONTROLLERPASSWORD","strict":true}' --compressed --insecure -c $COOKIE > /dev/null

# Download Statistics from controller using CURL
curl -s --insecure -b $COOKIE -c $COOKIE "https://$IP:$PORT/api/s/default/stat/sta" > $TMP_HOLDER

# Count active users by pattern match,  what an odd method, may not work correctly, but so far working for me
ACTIVE=`cat $TMP_HOLDER | grep -o $PATTERN | wc -l`
echo $ACTIVE
echo $ACTIVE

Result in command …

2- Odd method to acquire total number of Active Access Points Vs Down [Registered in UniFi Controller]

Bash script to acquire total number of registered access points (unifi AP-LR) and there status as well to compare Active vs down.

#!/bin/bash
# Script to query active clients by curl from unifi controller
#set -x
IP="10.0.0.1"
PORT="8443"
COOKIE="/tmp/cookies.txt"
TMP_HOLDER="/tmp/$IP.total.ap.txt"
PATTERN="adopted"
curl -s "https://$IP:$PORT/api/login" --data-binary '{"username":"admin","password":"CONTROLLERPASSWORD","strict":true}' --compressed --insecure -c $COOKIE > /dev/null
curl -s --insecure -b $COOKIE -c $COOKIE "https://$IP:$PORT/api/s/default/stat/device" > $TMP_HOLDER
ACTIVE=`cat $TMP_HOLDER | grep -o $PATTERN | wc -l`
DOWN=`grep -oP '\"state\" : \K[^ ]*' $TMP_HOLDER | grep 0 | wc -l`
echo $DOWN
echo $ACTIVE

Result in command …

3# Upgrade UniFi AP LR Access Point via SSH/CLI

We have few unifi AP-LR  Wireless Access Points in our company which are connected with the Unifi Controller ver 5.2.9.0 on windows 2008 r2 / x64 server. For some unknown reasons I was unable to upgrade the access point’s firmware from the controller. Therefore I upgraded all AP’s via SSH method which is posted below …

First download the appropriate firmware and upload it to some web server. (at the time of upgrading the latest firmware version was  3.7.21.5389 , you make sure to download latest one available)
Select your model / download from following link …

https://www.ubnt.com/download/unifi/

[Luckily I had local web server available so I simply put this file into my /var/www folder (for ubuntu)]

Now login in the access point via SSH , and issue this command

upgrade http://101.0.0.1/BZ.ar7240.v3.7.21.5389.161017.0923.bin

Make sure to change the path or ip according to your network. Once its upgraded it rebooted and new Firmware was 3.7.21.5389

I will post more info later … 3.7.21.5389
