Can I connect mysql client to a mariadb server?
Anyway, I fixed the problem via
MariaDB [(none)]&gt; Grant All Privileges ON *.* to 'remoteroot'@'192.168.0.15' Identified By '123456';
MariaDB [(none)]&gt; FLUSH PRIVILEGES;

where 192.168.0.15 is the host machine IP.
Then connected via
cmd&gt; mysql -h 192.168.0.17 -u remoteroot -P 3306 -p

Looks like working.
Still concerned some features face problems.
