Basically we can do firmware upgrade of the Ubiquiti UniFI by using the controller. Add the UniFI into the controller and then adopt it. Once it is connected to internet it will automatically detect available firmware update.

However using this method seems not work. The UniFi AP disconnected several times while updating. After waiting for around 30 minutes without success, I tried to upgrade the firmware using local upgrade via SSH. Using this method the firmware upgraded successfully.

Follow the below instructions on how to do firmware upgrade of the Ubiquiti UniFi AP

1. Download the firmware from https://www.ui.com/download/unifi. Make sure that you choose the correct firmware for your UniFi AP device.

2. Change the firmware filename to fwupdate.bin

$ mv BZ.ar7240.v4.0.69.10871.191109.0532.bin fwupdate.bin

4. Upload the fwupdate.bin file to the UniFi AP by using SSH / SCP

$ scp Downloads/fwupdate.bin ubnt@192.168.123.106:
ubnt@192.168.123.106's password: 
fwupdate.bin 100% 7032KB 1.3MB/s 00:05

Change the IP 192.168.123.106 to your Unifi AP IP address. Login using default username and password of UniFi AP (username: ubnt password: ubnt)

If you see errors when you tried to upload the file via SCP/SSH like below:

Unable to negotiate with 192.168.123.106 port 22: no matching key exchange method found. Their offer: diffie-hellman-group1-sha1

then you need to add the option in the ssh / scp command as follows:

$ scp -oKexAlgorithms=+diffie-hellman-group1-sha1 -c aes256-cbc Downloads/fwupdate.bin ubnt@192.168.123.106:
ubnt@192.168.123.106's password: 
fwupdate.bin 100% 7032KB 1.3MB/s 00:05

3. Login to the UniFi AP using SSH and check the current version. Check the UniFI information by typing ‘info’ in the terminal.

BZ.v2.4.8# info

Model: UAP-LR
Version: 2.4.8.2200
MAC Address: 24:a4:3c:98:27:78
IP Address: 192.168.123.106
Uptime: 381 seconds

As you can see above, the firmware version of the UniFi AP is version 2.4.8.2200.

4. Upgrade the firmware

fwupdate.bin file should currently be in the root / home directory. Verify by using ‘ls’ command. Move the fwupdate.bin to temporary folder (/tmp)

BZ.v2.4.8# mv fwupdate.bin /tmp/

Now run the upgrade script ‘syswrapper.sh upgrade2 &’

BZ.v2.4.8# syswrapper.sh upgrade2 &
BZ.v2.4.8# Switching to ramdisk
Writing 'u-boot ' to /dev/mtd0(u-boot ) ... [%100]
Writing 'kernel ' to /dev/mtd2(kernel ) ... [%100]
Writing 'kernel ' to /dev/mtd3(rootfs ) ... [%100]
Could not open U-Boot env MTD device: open(/dev/mtd1) failed: No such file or directory
Done

During the update, the Unifi LED will be blinking green and orange. You can ignore the warning / error message ‘Could not open U-Boot env MTD device: open(/dev/mtd1) failed: No such file or directory’

Login to the UniFI AP and verify the firmware version by using ‘info’ command.

$ ssh 192.168.123.106 -l ubnt
ubnt@192.168.123.106's password: 


BusyBox v1.25.1 () built-in shell (ash)

Lets surf to the guide

Unlock the Bootloader

Since it is not an official release / beta version, you need to unlock the bootloader to be able to flash an Android image. Follow the very detail guide on how to unlock phone’s bootloader from this website.

Install Android Tools (ADB & Fastboot)

For those of you who uses Apple macOS operating system like me, to install Android ADB & Fastboot we can use ‘Homebrew aka brew‘. Make sure that you have the latest version of Android tools otherwire the flashing will fail.

brew tap caskroom/cask
brew cask install android-platform-tools

Download the latest Android 8.1 image file

You can download the Android 8.1 developer preview image from official Android webpage here. Scroll down to near the bottom of the page to get the download links.

Unzip the image and start flashing

Once the image file is downloaded, unzip it and run ‘flash-all.sh’ script. For example I flashed my Nexus 5X (code-named with Bullhead).

$ unzip bullhead-opp6.171019.012-factory-65b5b35c.zip
$ cd bullhead-opp6.171019.012
$ ./flash-all.sh 
target reported max download size of 536870912 bytes
sending 'bootloader' (4620 KB)...
OKAY [ 0.179s]
writing 'bootloader'...
OKAY [ 0.136s]
...
[snipped]
...
rebooting...

finished. total time: 335.385s

It takes around 10 minutes to completely flash the image though the script says 335 seconds which is around 5 minutes and a half. Once the flashing process finished, the phone will automatically reboot into the new system.

Below is screenshot of Nexus 5X running Android 8.1 Developer Preview 2

Lets jump to the guide

Download the ISO image file

First thing first you need to download the latest install media which can be grabbed via its official website.

Create a bootable USB flash disk

If you use MacOS like me you can use ‘diskutil’ tools in macOS

diskutil list
diskutil unmountDisk /dev/diskN <— Change N with the number your USB flash disk mounted
sudo dd if=manjaro-deepin-17.0.6-stable-x86_64.iso of=/dev/rdiskN bs=1m
diskutil eject /dev/diskN

Watch this video on how to create a bootable USB stick on macOS.

Prepare the partition

We can use Disk Utility to partition our disk. Create around 50GB or more of disk space for Linux. It is up to you to set the disk space partition for you. Linux desktop can be installed on 20GB disk but it would be limited space. I use Samsung EVO 850 with 500GB so I set the disk partition to around 100GB. Set the partition format to MS-DOS(FAT). We can change to EXT4 Linux file system format later in the installation stage.

Watch this video how to create partion in macOS

Boot into the bootable USB flash disk

Once everything is ready, insert the USB flash disk to a USB port and reboot the machine. Press and hold the ‘Alt/Option’ key while booting until you see disks to boot. Select the EFI boot disk to start Manjaro Live from the USB disk. After it finishes booting, double click ‘Install Manjaro’ icon in the desktop to start the installation. Follow the on-screen installation instruction until you arrive at Partition section as in the image below. The image may be different with yours as it depends with your disk / system partitions.

This is the most tricky and fun step. According to the installation guide, an EFI system partition is necessary to start Manjaro, without it your system may fail to start. So lets create an EFI system partition for Manjaro. As in the image above, the selected partition /dev/sdb3 with 102.4GB of space is the partition we created before intended for Manjaro. Select it and then click ‘Edit’ button. In the edit partition window, set the config as below:

Size: 200MB
Content: Format
File System: fat32
Mount Point: /boot/efi
Flags: boot, esp

Then click OK.

Then set the remaining unallocated space to the Manjaro system as in the image below.

Click OK button to confirm. You should see two new partitions, /boot/efi with FAT32 file system and / with ext4 file system as in the image below.

Click Next button to the next step to create new user.

Fill up your username information on this step to log in to the system.

Review the new partition and make sure that you partitioned the right partitions. Click Install Now button to proceed with the installation.

The installation process would take several minutes depending on your hardware configuration. If there is no error, it should be installed successfully.

Installation is completed. You can restart the system now.

Post Installation

By default Manjaro GRUB only detect Manjaro partition. It does not detect MacOS system automatically. To boot to MacOS system from GRUB we need to add a menuentry of MacOS in /etc/grub.d/40_custom as below:

menuentry "Mac OSX" { exit }

Then run the ‘update-grub‘ command to take effect.

sudo update-grub

You will see the ‘Mac OSX‘ boot option in the GRUB while booting as in the image below

Some screenshots of beautiful Manjaro Deepin 17.0.6

Below is some screenshots of Manjaro Deepin 17.0.6 running on my Macbook Pro mid 2012 dual boot with macOS High Sierra.

As you can see in the image above, the OS version is Manjaro 17.1pre3 Hakoila. To get this version, run ‘sudo pacman -Syu‘ to update the system to the latest version.

Manjaro Deepin File Manager looks much like Finder in macOS.

System Activity in Dark mode. You can simply change it to Light mode.

Manjaro Deepin Music app in dark mode as well. It is so beautiful, isn’t it? Want to install it on your Macbook dual-boot with Apple macOS / Mac OSX? Just follow the installation procedures above.

LG Nexus 5 is still a great Android phone though it was released 3 years ago. Unfortunately Google stopped to release official Android OS for Nexus 5 until Android 6 Marshmallow. It means that they will not release Android 7 Nougat and newer for Nexus 5.

Fortunately there are available custom Android ROMs which are based-on Android 7 AOSP such as CyanogenMod 14.1 now LineageOS 14.1, and ResurrectionRemix 5.8.0. LineageOS is the successor to the popular Android custom ROM CyanogenMod after it was discontinued by Cyanogen Inc. on December 2016.

Backup everything before following the guide below!

To install LineageOS 14.1 on Nexus 5, follow the step by step below:

Install TWRP Recovery

Make sure that you have installed TWRP Recovery on Nexus 5. If not follow this guide how to install TWRP Recovery on Nexus 5.

Download the latest LineageOS 14.1 image

You can download the latest LineageOS 14.1 image from its official website. For Nexus 5, go to this page to download it. At the time of this writing, the latest version is lineage-14.1-20170131-nightly-hammerhead-signed.zip.

Download the latest Google Apps

We will use OpenGApps. You can download the latest OpenGApps from www.opengapps.org. Select the ARM, Android 7.1, and pico / nano variant. Copy / save the files into internal storage / SDcard of Nexus 5.

Reboot into TWRP Recovery

To reboot into recovery, plug in the Nexus 5 into laptop / computer using USB data cable. Run ‘adb reboot recovery’ to reboot into recovery.

Wipe the device

In the TWRP Home menu, select Wipe > Advanced Wipe. Select Dalvik / ART Cache, System, Data, and Cache. Do not select the Internal Storage otherwise you will lose the data. Then Swipe to Wipe.

Install LineageOS and GoogleApps

sudo yum install android-tools

In Debian / Ubuntu / LinuxMint / ElementaryOS:

sudo apt-get install android-tools-adb android-tools-fastboot

In Windows, you can follow my previous post in this post.

Connect the Nexus 5 to computer / laptop using USB cable data

We need to connect Nexus 5 to a computer  / laptop using USB cable data to execute commands below.

Flash the TWRP into Nexus 5

Open Terminal (in Mac OS, Linux) or Command Prompt (in Windows). First reboot it into bootloader.

adb reboot bootloader

When executing the above command, you may be prompted to allow USB Debugging. Tap OK to allow it then re-run the command above to reboot into bootloader. Make sure that the LOCK STATE is unlocked, if it is locked you need to unlocked it first. Follow the my previous post how to unlock it here.

Now using fastboot tool, flash the TWRP into the device:

fastboot flash recovery twrp-3.0.2-0-hammerhead.img

Sample screenshot.

After flashing the TWRP recovery using the command above, I run command ‘fastboot reboot‘ but it does not work. Instead use Volume UP/Down to select Recovery Mode then press Power Button to reboot into TWRP Recovery.

Once you press the power button, it should reboot into TWRP recovery.

In the step 4, after destroying the vagrant box, we need to run ‘vagrant up’ to bring up the new Homestead. Unfortunately, my experience was it unable to boot. It stuck on “SSH auth method: private key” for around 5 minutes then throwing error messages saying that “Timed out while waiting for the machine to boot”. On the third paragraphs of the error messages, it clearly said that “make sure that networking is properly
working and you’re able to connect to the machine”.

Timed out while waiting for the machine to boot. This means that
Vagrant was unable to communicate with the guest machine within
the configured (“config.vm.boot_timeout” value) time period.

If you look above, you should be able to see the error(s) that
Vagrant had when attempting to connect to the machine. These errors
are usually good hints as to what may be wrong.

If you’re using a custom box, make sure that networking is properly
working and you’re able to connect to the machine. It is a common
problem that networking isn’t setup properly in these boxes.
Verify that authentication configurations are also setup properly,
as well.

If the box appears to be booting properly, you may want to increase
the timeout (“config.vm.boot_timeout”) value.

How to solve this issue?

To solve this issue, simply run the VirtualBox manually (by clicking /Applications/VirtualBox) then check on the network setting of the VirtualBox. I found that the ‘Cable Connected’ option is not checked.

Please make sure this option is checked. The re-run ‘vagrant up’ command. The new Homestead should boot up properly.

If you are working as a network administrator, Aten UC232A USB-to-Serial converter is a must have. This device converts USB to Serial port so it helps us to console network devices such as Cisco, Juniper, Dell Force-10, and etc using our notebooks or laptops.

Here are the step by step how to install the driver

Disable the System Integrity Protection. You can follow this tutorial how to disable it.

Download the Prolific PL2303 Mac OS X driver from here then install it. Simply follow the installation guide document included in the downloaded zip file. Once installed, reboot the Mac.

According to the installation guide provided by Prolific, after the installation completed once we connect the Aten UC232A usb-to-serial converter to our Macbook it should be detected by the Mac OS X system. But there is no ‘tty.usbserial’ under /dev directory. To solve this, simply download and install the latest driver provided by Aten. You can download it from its official website. In the near bottom side of this page, click the ‘Support and Download’ tab to download the driver. Yes at the time of this writing, the latest available driver is for OS X Yosemite 10.10. Just download it, I have proven it working for El Capitan and Sierra. Once downloaded, install it and reboot the Mac.

Then Plug the Aten UC232A USB-to-serial converter then verify that the device should be attached to /dev/tty.UC-232AC

Viola. You have successfully install Aten UC232A driver and ready to use.

If you upgraded your Mac to macOS 10.12 Sierra or your iPhone to iOS 10 you might be surprised that PPTP client is not on the list when adding VPN interface. Apple will no longer support PPTP client  starting from macOS Sierra and iOS 10. Alternatively you can switch to use L2TP VPN over IPSec which offers better and more secure connection.

In previous post I have shown you how to configure Mikrotik as an L2TP VPN server. We will use the account configured on the Mikrotik as the login account.

The step by step how to setup L2TP VPN macOS Sierra

Follow the below step by step on how to setup L2TP over IPSec on macOS Sierra

1. Open System Preferences then select Network

In the Network settings, click the + (plus) button to create a new service (we will create a new VPN service)

2. Select the interface for the new service

To create a new VPN service, configure the interface as below;

Interface: VPN
VPN Type: L2TP over IPSec
Service Name: choose a name for this new service. By default the name should be VPN (L2TP)

3. Enter the VPN server address and your account

Make sure the L2TP VPN server has been correctly configured. If you use Mikrotik, you can follow my previous post on how to configure Mikrotik as L2TP VPN server.

Server Address: the IP address of your L2TP server
Account Name: your login name to your L2TP server

4. Configure the Authentication Settings

Click on the Authentication Settings to configure auth and machine authentication.

Password: the password of your PPP secret
Shared Secret: the IPSec shared secret

5. Click Advanced button

Make sure that the ‘Send all traffic over VPN connection’ is checked. Then click OK button. Complete the setting by clicking Apply button.

6. Connecting to L2TP VPN server

To connect to the VPN server, click the Connect button just under the Authentication Settings. Once it is connected, you can see the connection status, the connect time, and the IP address assigned to your Mac.

I hope this post can help you on how to setup L2TP VPN on macOS Sierra.
