Multiple split by '=' character may cause wrong hash addition because

Many hosts are not resolved with first lookup b32->b64, but if we query
2nd time, host can be resolved. Because of this, some registered hosts
may be never seen while they actually up!
Master log file first opened as root, than daemonization with privilege
drop happens and master then unable to log to this logfile because of
insufficient permissions. So chown logfile to "runas" user to avoid this
situation.
