UBNTMOD check range of IP addresses and see if they resolve DNS

The following uses the ubntmod.sh script to check a device then report if it is resolving DNS or not. ip=”192.168.1.” specifies the first part of the ip, the “for ((i=1; i<=254;i++))” tells it to go from 192.168.1.1 – 192.168.1.254, change the beginning and ending number if you want to change the ip range.

ip="192.168.1." && for ((i=10; i<=30;i++)); do if ( fping ${ip}$i -r1 | grep alive); then ./ubntmod.sh -i ${ip}${i} -e ; else echo ${ip}$i not alive; fi ; done

Broken out for easier reading.

ip="192.168.1." 
for ((i=10; i<=30;i++))
do 
if ( fping ${ip}$i -r1 | grep alive); then 
./ubntmod.sh -i ${ip}${i} -e 
else echo ${ip}$i not alive
fi 
done

If the script is able to log into the device and resolve DNS you should get

192.168.1.1 Resolves DNS

Upgrade Firmware on Ubiquiti Airmax Equipment from the Command Line/SSH

Upgrading the firmware via the command line is super easy.  Basic steps are

  1. Upload firmware file to radio using ftp, scp, or download directly to radio using wget
  2. Move the firmware the /tmp and rename to fwupdate.bin
  3. Upgrade the firmware by running
ubntbox fwupdate.real -m fwupdate.bin

More Detail explanation

Downloading Firmware to Radio

There are a couple of ways to get the firmware uploaded to the radio

  1. Download from Ubiquiti’s website and upload via ftp, scp, filezilla or like
  2. Download directly to the radio using wget

Using wget

ssh into the radio.  Change username and ip address as needed.

ssh ubnt@192.168.1.20

cd to the /tmp directory

cd /tmp

Find the firmware file on Ubiquiti’s website, accept the terms, copy the link and paste the link in the terminal after wget.  Replace the below link with the appropriate firmware link.

wget https://dl.ubnt.com/firmwares/XC-fw/v8.4.2/WA.v8.4.2.35930.171017.1722.bin

If you run into issues with wget, try using curl.

curl -k -o fwupdate.bin -L https://ui.com/downloads/firmwares/XC-fw/v8.7.13/WA.v8.7.13.47729.240606.1144.bin

Here is what the options mean:
-k mean insecure, which allows us to download via https.  There is a certificate error if not used.
-o fwupdate.bin, saves the output file as fwupdate.bin
-L means follow redirects

Installing Firmware

Rename firmware

mv *.bin fwupdate.bin

Start the upgrade

ubntbox fwupdate.real -m fwupdate.bin

The radio will now upgrade and reboot

Another Method.  Using the ubntmod.sh script

Another way to upgrade a radios firmware from the command line is to use the UBNTMOD tool.  More info on the UBNTMOD script is available here.

Make sure you have the firmware downloaded to your computer and run ubntmod.sh with the “-U” upgrade option.

Example,

bob@localhost:~$ ./ubntmod.sh -i 192.168.1.20 -U WA.v8.4.2.35930.171017.1722.bin
