Hello Ilya, my first hint is to remove the 'sql_host: localhost' line; it avoids the connection through the usual '/tmp/mysql.sock' pipe file and makes pmacct to establish the TCP connection to 'localhost:3306'. If you really need this, try rewriting it as 'sql_host: 127.0.0.1'.
Next, check that the 'acct' table really exists and that the 'nfacctd' user has the right priviledges on it. Let me know ! Cheers, Paolo
