I'm trying to encode the passwords that appear in kamctlrc file. I don't know if it is possible.
Is there a way to do it?
Best wishes, D.
kamctlrc is the config file configuration file for kamctl and kamdbctl tools, which use it to get database info, default domain and some daemon config options.
It's a text file with ATTRIBUTE=VALUE formatting.
The passwords are configured in plain text in the config file, if you edit kamctlrc with a text editor (if you've installed from the repos it'll probably be in /etc/kamailio/kamctlrc ) you should see fields like DBRWPW=password and DBROOTPW=password for the Database Read/Write Password and the root database password respectively.
Here's an example kamctlrc file from the Kamailio team.
Here's some info on setting up kamctlrc to work with MySQL database backend.
