How to ssh and change root password
If you're on windows, you can use putty, download here
Once donwloaded, you just open it, and enter your PBX IP under "HostName (or IP Address)" and next to it, under Port, put in 22 or 20022 (we use different port, depending on your Asterisk flavor)
You will login as root (see welcome email for the password). You can find a copy of the welcome email in our client area under Emails section (Find "Hello, Your-name-here" menu on top right -> click Emails).
If you're on linux or Mac, you just type below in your terminal window/app
ssh root@your-pbx-ip-here
or on port 20022, you type
ssh -p 20022 root@your-pbx-ip-here
To change root password, you type
passwd
Note: If somehow you don't get login prompt, you maybe banned by firewall in pbx. Try wait 20-30 min for the firewall to unban automatically or try from new place.
For mysql root password, you can reset it following https://dev.mysql.com/doc/refman/8.0/en/resetting-permissions.html
