Resetting Root Password for FreePBX 14.0.5.1–Sangoma Linux 7

2 Comments

Many people have been through this same problem either due to forgetting the root password, typing it wrong or due to console language conversion issue.

Mine was due to using a remote console which didn’t translate my keyboard properly and caused a wrong password.

So I ended up having access to the GUI screen but not the root. So first thing came to my mind is should I reformat the machine and reinstall it since it doesn’t take long time? but no I like challenges and started digging into how do I reset the password.

Since I do still have the access to console I can try from the Kernel, the default ISO install FreePBX with Sangoma 7 Distro which is based on Centos Kernel 3.10.0-862.2.2.3 el7.x86_64.

So I first attempt I tried was following the same method of resetting root password on Centos through Kernel.

1- Restarting the machine to get into Kernel:

When Restarting Press E to edit the Kernel

Once pressed E you will get this screen:

2- Edit the Kernel:

Scroll down until you find “rhgb quiet” and replace it with “init=/bin/bash” without quotes.

So eventually it’ll look like this

3- Resetting Root Password:

Once it’s changed, press ctrl-X to initiate the process of resetting the root password:

You will get Bash cmd prompt, Type the following commands

A- First to check the status of root partition by running following command on the single user mode.

Mount | grep root

In this distro of Linux you might not get anything but normally you should get partition details.

B- To make the partition writable, you’ll have to type in the following command

mount -o remount,rw /

C- To Change the root password type

passwd root

Type your new password and you’ll get a message that all authentication tokens updated successfully

After this restart and try to login, and you’ll see that it works fine

Result:

After restarting the machine, I tried to get into web GUI to start configuring the FreePBX but I received the following error:

Whoops\Exception\ErrorException (E_ERROR)

Class ‘PicoFeed\Reader\Reader’ not found

After doing some research it was obviously an error related to a recent update pushed by FreePBX

Solution:

and the solution was running this cmd

fwconsole ma upgrade dashboard –edge

Corrupted Databases on Exchange 2010/2013/2016 and how to recover with Stellar Phoenix Mailbox Exchange Recovery software review

Leave a comment

23 May 2018 By Mohammed Hamada

Exchange administrators go through hard times when servers crash, Reason of these crashes can vary but the result will most likely be a corrupted Database with dirty shutdown status.

In my case as an Exchange Senior Consultant I came through many clients who have had power issues or an update that cause their Servers to go down and crash Exchange servers. Some of them had 20K users with a very busy environment and huge amount of data being written on their databases.

Most organizations will likely have backup solution which backs up the database on daily basis but I have seen that even these kind of organizations will still lose data due to the interval of data backup they have which is around minimum of 12 hours. so if a database gets corrupted in +5 over the past backup then there would be a disaster.

This where recovery solution is a must, Stellar Phoenix Mailbox Exchange Recovery have the capability to recover data in the mailbox which is no longer visible on Exchange but it is still on a backup for example or from a corrupted database since has the mechanism of rescuing a corrupted database which can’t be mounted or read by Exchange server.

The installation process is pretty straight forward. You can check the demo version and see for your self how that this software can read the database and mailboxes prior to make any decisions on purchasing.
