PLDT Fiberhome Super Admin Account

As I have mention on my previous post on how to make available the "Admin Account Unavailable" that there is no need anymore to alter the 1.xml and 2.xml for the PLDT Fibr ONU AN5506-XX-XX web GUI accessible via http://192.168.1.1/fh, gaining to the web page menu setting is either by using the PLDT Fiberhome Super Admin account default username and password or thru Serial console communication port. Yes, its more complicated on the console com port because it is a Command Line Interface (CLI) unlike the fiberhomesuperadmin you are on the Graphical User Interface once you login you can just click it, to enable or disable the "Web Admin Switch" that's how easy and user friendly interface it is.

All ONU/ONT products of Wahun Fiberhome Technologies are ship with three(3) credentials, these two(2) default username and password management account remain unchanged to where ever country and ISP it will be used, but the other Administrator account such as "adminpldt" username and the password is customized by the ISP like PLDT Fibr HOME brand. The ISP Products branded with “FiberHome” have been exported to over 90 countries and regions worldwide including the Philippines. If you can not find in you ISP country the expose admin account perhaps you can Google it you may find answer at 3BB, PTCL, VietTel or maybe in Brazil, use google translate the friendly and so helpful to provide the context interpretation into your desire languages.

I am providing a screenshot again to make it probe that the "Web Admin Switch" are existing on the Management menu once you are log in as the Fiberhome Super Admin account, the username as I have said will remain unchanged as "fiberhomesuperadmin" its small caps this is case sensitive while the password is also remain unchanged as by default. But then how to access the Fiberhome Super Admin account if you do not know the default password even you have already Google the user manual of your Fiberhome ONU AN5506-XX-XX, its in a pdf format. Answer, the Serial Communication console port is there available and very accessible, you can even wipe out the entire filesystem, backup your config, likewise the firmware you can even copy via winSCP without pains.

You can try BinWalk its a powerful tool for firmware you can unpack, repack, edit, read and write even modify the cfg and the web. So many free HEXeditor that you can be use for editing not to mention the rest. The architect of this Wahun Fiberhome ONU/ONT I salute so brilliant, if just take a closer look of the internal OS and filesystem of the AN5506-XX-XXX. Just imagined it has two boots and a twin filesystem in case the first get fails the other will automatically take over.

PLDT Fibr AN5506-04-FA Debug

This is another episode of PLDT Fibr AN5506-04-FA ONU/ONT, today I would like to introduce to you the Debugging environment of Wahun Fiberhome AN5506-XX-XXX also applicable to this product series. What we have here upon digging into the inside of the terminal we got so many interesting stuff that we can exerciser on the command line interface, those guys who are fun of graphical interface they don't love this taste. How to get into this text envy you can login via telnet or thru the serial console.

If you want to access this terminal on telnet first thing you have to do is you must enable the "telnet switch" on the web GUI by using the FiberhomeSuperAdmin account username and default password. The other method is via console communication port. The above screenshot is the available command when you press the (?) question mark sign, or in other words its a help symbol.

On this second captured screen is another way on how to enlist all the function command for debugging the ONU/ONT Fiberhome AN5506-XX-XXX series. So much interesting text command we can try to execute here but be careful the rest of these debuggers you might be able to paralyze your all in one equipment. If you do not have the spare Optical Network Unit beside you do not desire typing those listed command you because you will interrupt your internet fiber broadband connection. There is another command line interface of this AN5506 series device which if more friendly and is safe to execute the listed commands, its the user config command line interface. Here you can also manipulate your desired config settings, you can find the startup-config and the running-config it most likely identical to CISCO IOS command line interface.

On this section is more likely for calibration purposes only and only those PLDT network engineers has more capacity to understand this category of work. If you are noob like me  take precautions on hitting those enumerated debug command.

PLDT Fibr AN5506 Admin Account Unavailable

It is really frustrating every time you want to do something like tuning up your ONU/ONT for the sake of your network security, gaining access to your home wireless access point, or even worst if someone can just step into your AN5506-XX-XXX without your knowing and install malicious backdoor onto it. There are so many silent *bots out there hanging around for lease and the most often victims are those residential gateway like us who owns this kind of lousy PLDT Fibr ONU/ONT equipment.

What even worst is when you are limited to access your own device supplied by your Internet Service Provider like PLDT who is monopolizing every inch of this so called Internet of Things. I am one of you who also face the same problem who's Optical Network Unit is being lock down  by Philippine Long Distance Telephone Company every time I open my web GUI I stuck on "Admin Account Unavailable".F8ck!

"You are prohibited to open the rest of the menus and settings of your own ONU/ONT because you have zero knowledge". Imagined that you have to beg for "adminpldt username and password account" for you to safeguard your entity, what the heck?  Just recently, now you must have to sign for a waiver if you want to have the admipldt account privilege otherwise when you get BRICK your PLDT Fiberhome AN5506-XX-XXX you have to pay for the replacement even if this ONU/ONT can just be reflashed by inserting a USB pendrive on its USB ports for firmware recovery. DAMN!

Try to make a call 171 to get help and your call get acknowledge after 35 minutes, yes thirty five minutes your ears will be swollen listening to the Interactive Voice Response System of my beloved PLDT. You will then be given a Ticket, for how long your issue will be solve? you have to wait until the Technical Engineering team can solve it. You still have an option is either to hire a Shifu from Symbianize or a Guru at GitHub. If you can find these two people on the said forum then you have to do it by yourself, dug into Google the biggest library on the globe hoping you can find hint for your problem.

After digging for about four months I just found some clues, I realize that there is no need to alter the 1.xml to 2.xml for you to get the adminpldt full access to navigate all the Menus and Settings. Its only the PLDT Fiberhome Super Admin account have the right key to make the adminpldt account available.

The PLDT FiberhomeSuperAdmin account can do this job, on the Management Menu you find this if you have login as fiberhomesuperadmin username at http://192.168/1/1/fh. Imagined they can just remotely switch the adminpldt account either to enable or disable it at any time any where they want it via web GUI or thru Telnet. There is more on this Menu Setting you can also find the OMCI Debug Switch and Telnet Switch if you desire to activate it or deactivate it. They can leave it for sometime open or give you an access for only three(3) days as they have given permission to those who are Netizens in GitHub forum.

If the PLDT Network Engineering Team will read this post surely they will inform their superior to immediately a mass patch this mole found on Wahun Fiberhome AN5506-XX-XXX products. This will be another headache to the PLDT concerning gaining access to the Fiberhome ONU/ONT device. Don't worry even though you can not have the privilege of FiberhomeSuperAdmin account to gain the full access setting of the web GUI, the Serial port is waiting for you its more than the privilege of fiberhomesuperadmin.

Disclaimer, this is not a tutorial this is provided as it is. I wish to have more time to write up more about PLDT FiberhomeSuperAdmin account. The Telnet Switch and the OMCI Debug Switch.

PLDT Fiberhome AN5506-04-FA RP2627

Today is not a surprise that once you open your PLDT Fiberhome AN5506-04-FA web GUI you have a lousy Menu settings on your ONU/ONT, the software version is updating upon upgrade are not stopping. As I open my ONU web GUI the version as I have expected will be updated again from my previous updated RP2616 now its RP2627. I login as an ordinary user account I can see nothing have change though the PLDT Engineering Team made this upgrade remotely. I usually try occasionally to login also the username adminpldt and password 6GFJdY4aAuUKJjdtSn7dC2x but not to expect that I can open this adminpldt account, because I know it always prompt me to the unavailable admin account.

When I saw my software version have change from my previous RP2616 to RP2627, I tried open the adminpldt account with the password mention above, oh Lo! It logs me in it didn't prompt me the unavailable admin account. I logout again and try to login with the same username and password. Yes it goes on and logs me in, are they forgetting something after they updates my ONU/ONT AN5506-04-FA or this is just a backlog?

As you can see on the screenshot above, its the PLDT Fiberhome AN550-04-FA web GUI status device information. I am still looking for this R:P2627 updates if what did the PLDT Engineering Team revised  inside this ONU/ONU firmware. I guess its nothing new, they just hide the parameter on the *.xml and the *.asp files so the Netizen like me have nothing to click on the pages of the PLDT Fiberhome ONU.

Here's the rest of the adminpldt account web GUI features and settings. If you take a look closely on this Menus nothing have been redo except those previous clickable apps are now mysteriously disable by default and no longer be enabled even how much clicks and apply you are going to do.

Firebug and Web Developer are still among the best css tool inspector if you want to investigate their dirty lefties program on this forbidden web pages. There is also a good way to totally penetrate this nullified access is using the Serial console, USB-to-TLL or UART microcontroller can also be use to get the access on the console port so cheap nowadays this device and can be purchase online for a few penny.

Yes this PLDT Fiberhome AN5506-04-FA ONU has a nice four pin header on the board right next to the SOC Integrated Circuit which is easily to be identified by just using a multi-metter to determined its TX and RX so you can see and read the logs. Going inside the console port you need a username ad password of course, but don't worry Wahun Fiberhome products such AN5506-XX-XXX default password can be found on the user manual just Google it. Once you are IN, then retrieving all the data inside can easily to be copied with the SCP if you do not want to mess with your USB pendrive.

On the shell your privileged  is you are the root so you can modify, read and write to any file or the filesystem, even erase it entirely so be careful before doing anything else you MUST backup the entire system in the case of disaster may occur you are safe, you may be able to upload the entire image back to the ONU, otherwise if you get BRICK you are good bye PLDT will not replace you AN5506-XX-XX.

The PLDT Fiberhome AN5506-XX-XXX is easy to be deBRICK there are bunch of way to reflash the firmware, unlike P1 CPE and HUAWEI. If you need help on your device ofcourse I can help you but I am not available at all times, I am also a busy person. I want to post on my next article by disecting this all Main Menu into their sub-Menus.

PLDT Fiberhome AN5506-04 Slowing After Bridge

I have been satisfied with my PLDT Fibehome internet fiber broadband connection for several months with my download speed of up to 1.2Mbits per second per download. I have no complain about my subscription plan because it is a just and fair with my monthly billing. When the PLDT Fiberhome Technical Team installed my fiber connection my ONU/ONT Fiberhome AN5506-04-FA came with older software version RP2610, the PLDT Manila NOC (Network Operation Center) advice me not to power off the 3in1 device for software updates to RP2616. Yes the AN5506-04-FA is a three in one equipment, it is an ONU/ONT bundled with digital Modem (Modulator De-modulator) similar to media converter likewise a Router for routing, and at same time a WAP (Wireless Access Point) with two Bands, one is 2.4GHz and the other is 5GHz frequency, also a four LAN port and two POTS ports for wired PCs and Telephone.

It has been long time ago that my PLDT Fiberhome internet fiber connection from the time being installed I got no worry about even though the web GUI (Graphical User Interface) has only limited settings,with the helps of those Gurus out the in gist.github.com I able to fully access and navigate the rest of the ONU/ONT web GUI Menu and settings. Early on the month of April the tricks to navigate the rest of the Menus and settings with admin username and password 1234 are unavaible already. After checking the software version, oh! RP2616 is no longer on the Status Device Information but rather an update being done now its RP2621 already. The gist.github.com and symbianize.com altering 1.xml to 2.xml will log you out and prompt you the return2login.html. In other words me and the rest of the Netizen who use the same agenda will now have to end the enjoyable downloading that we have on the previous tricks and settings.

So I make a call and dialed 171, I speak to the CSR and made a request for Bridge Mode of my lousy PLDT Fiberhome ONU/ONT AN5506-04-FA software version RP2621 hoping that from Routing Mode to Bridging will solved my problem. This is purchasing a new wireless router to served for my said purposes. One day after PLDT Technical guy calls up and talk to me and ask me what is my concerned, I said, I just need to be Bridge my ONU/ONT AN5506-04-FA I will just provide another wireless router for me needs.

He told me just to hang the phone for a while and after three (3) minutes he told me to unplug the power adaptor and plug again then power it up. Yes so quick, after he told me to verify if its already in the Bridge Mode and I said yes. I was so happy on that day that my PLDT Fiberhome AN5506-04-FA ONU/ONT is now on Bridge mode.

So finally my goal on Bridging the ONU/ONT is now done worry not because my new TP-Link WR841N can handle it, this kind of router is cheap with fair price and it is also a well know brand in data communication. So from that day I didn't check my speedtest if there is improvement or worst than before. A month have pass I notice it when I download files that my downstream now is on 50Kbits, I keep on downloading until I come to the conclusion that there is something wrong with my speed. Even for YouTube video streaming it took sometime to load the video to play. When I read on the other thread some Netizen also facing this kind problem after changing their ONU/ONT AN5506-04-FA from Router mode to Bridge mode the speed of the downstream get worsen that what they are to expected.

Reading upon research from other thread online about ONU/ONT and OLT, I came to the conclusion that on the side of Optical Network Unit or Optical Network Terminal it won't serve the purpose, you are limited and can be locked, on my observations all the supervision and management are on the side of the Optical Line Terminal (OLT). The OLT can restrict your upload and download, it has also the authority even to null your ONU/ONT LAN ports to a single PC only. Of course there is a remedy for this, remember there is no secured system made by human being there is always a way in that is why they won't stop and always keep on patching from time to time because they know its INSECURED.

How To Backup Fiberhome AN5506-04-FA MTD

First and foremost before doing the backup of the ONU/ONT Fiberhome AN5506-04-FA make sure you are the owner of the device, secondly you responsible for the damage you have done, doing this is a risky and you might be able to brick the equipment if mishandled incorrectly. As a precaution, preferably you have a spare ONU/ONT on your hand in the case of disaster you might not disrupt your internet connection.

How do we backup the ONU/ONT Fiberhome AN5506-04-FA mtd aka firmware?

There are two available terminal that we can gain access on AN5506-04-FA one is via Telnet terminal and the other is via Serial communication port. These two accessible console is also applicable to the other Fiberhome ONU/ONT AN5506-XX-XXX series if you want to explore your own device to prevent your Internet Fiber ONU device being remotely updated upon updated its firmware for you not to have the vast features configuration and all the other setting being hidden by your greedy ISP. To begin with, lets check if the port of Telnet is open we can use NMAP to verify it or other similar port scanner that may give us same result. If the Telnet port is close then we do not have other choice but to open the top cover of the ONU/ONT AN5506-04-FA because Serial Console header is residing on the surface of the board.

What we need for serial communication for us to be able to communicate with AN5506-04-FA Serial Console is a serial com port, or any USB-to-Serial converter device. Then a HyperTerminal, you can also use Putty,you might want to be comfy Hercules will do or any other application alike will serve for data communication between two digital devices. Once you are plugged in then the console terminal is ready. Communication baud rate is 115200 8n1, if everything is properly hooked up, once we fire up the power ON you should see the U-Boot message just started like this.

The USB flash drive is detected as sda1 device (/dev/sda1) and the mount point is located at (/dev/shm/usb/media/sda1), now we have to unmount the USB pen drive device first by not unplugging from the USB port of the AN5506-04-FA. Then mount again the USB flash drive with this following Linux command.

umount /dev/sda1

mount /dev/sda1 /dev/shm/usb/media/sda1

We are ready now for backing up all the MTDs of Fiberhome ONU/ONT AN5506-04-FA, we'll make first folder on the USB drive with this command.

mkdir /dev/shm/usb/media/sda1/backup

Now use these following Linux commands for back up the list of all the AN5506-04-FA MTDs.

How To Change MAC Address on Embeded System

I have just purchased an ONU/ONT Fiberhome AN5506-01-A at AliExpress a well known online store in Asia region. I decided to buy it because of my Fiber Internet Service Provider is locking down all their Optical Network Unit aka Optical Network Terminal which only allow their subscriber to a limited privileges to the CPE device settings and configurations. My ISP are updating their device remotely via OMCI and not through TR069, the updates or the ONU firmware upgrade is done without your knowing to whether it is online or offline it can be done. Exactly the updates upon updates is done prior without noticed the so called firmware!

My problem is that the ONU AN5506-01-A came in to me is with the Software Version RP0521 and the Hardware Version is HX-2.134.318A9G, this stock firmware also has a limited basic configuration settings. Meaning some of the Menus and sub-menus are being omitted, you can not set the WAN to Bridge Mode on the web Graphical User Interface (GUI) its explicitly as Router mode only. Another thing is that the LAN menu or the setting is missing from the GUI, you can not modify your desired IP configuration, enabling and disabling DHCP server and relay are out of the context. Most of all its NOT a plug and play electronics equipment.

Why do I need to change the MAC Addresses?

Unlike xDSL internet connection, your ISP will just ask you what username and password you wish or they just provide you the username and the password for you such as yourname@isp and your password, most often you can even choose your desired password as you wish for it. Then choosing and buying your own personal wireless modem router from low to mid or high class residential gateway is just on your finger nail because the device is a plug and play after you input the given username and password given by your ISP its now connected to the internet.

Now here we go, I took the fiber patch cord from my ONU/ONT ISP and then plug it to my new Fiberhome AN5506-01-A the LOS LED turns off from blinking Red, and the PON LED now don't stop from blinking Yellow. Obviously the PON LED means that the ONU is not connected to the network or to the OLT it needs an authentication, once the ONU is connected the PON LED lit will be steady in yellow color.

To get the AN5506-01-A to be connected to the OLT of my ISP we need to copy first the PON MAC address of the ONU/ONT and Serial Number of it that was provided by the ISP and replicate to the new ONU/ONT AN5506-01-A.

How do we change the PON MAC Address of the Fiberhome AN5506-01-A?

The ONU/ONT Fiberhome An5506-01-A is a ARM Linux Embeded system, going to the web GUI there is no way of changing the PON MAC Address. The chances of spoofing the Passive Optical Network MAC address is in the Linux environment, we can log in via Telnet and we can get access to its Command Line Interface (CLI), after reviewing the commands it is very reluctant to clone the MAC address. Another option is thru Serial communication port, this is a terminal also a CLI were we can get help from Busybox.

To change the PON MAC Address of AN5506-01-A heres the command.

First find the physical MAC address of your ONU/ONT device by running this following command :

# ifconfig -a | grep HWaddr
pie0  Link encap:Ethernet HWaddr 00:1A:2B:3C:4D:5E

The hexadecimal numbers in blue denote my AN5506-01-A ONU/ONT PON MAC address.

Next, type this following commands.

# ifconfig pie0 down
# ifconfig pie0 hw ether 00:A1:B2:C3:D4:E5
# ifconfig pie0 up
# ifconfig pie0 |grep HWaddr

To check again if the PON MAC Address have been change already just repeat this following command.

# ifconfig -a | grep HWaddr
pie0  Link encap:Ethernet HWaddr 00:A1:B2:C3:D4:E5

This is just a temporary solution, once the machine is being rebooting it will just go back to its original MAC address.

The final option we can do is still via Serial port but now it would be thru U-Boot Linux environment. Power ON the ONU/ONT
then you will see U-Boot started you must be quick in 3 seconds it will continue to boot to the second level of booting. You have to hit any key in 3 seconds.

Here's the following command in U-boot.

# setenv ponmac 00:A1:B2:C3:D4:E5

# saveenv

saveenv command means saving the environment variables. This will save permanently to the SPI FLASH storage.

You must see something like this log messages.

Finally you can now use your ONU/ONT AN5506-01-A, just input the Serial Number of your device the OLT of your ISP provider will now give the authority to be connected to the system.
