after making change in  file xhimera.conf
i try ./xhimera
but this message appear :

"Error: To use xhimerad, or the -server option to xhimera-qt, you must set an rpcpassword in the configuration file:
/root/.xhimera/xhimera.conf
It is recommended you use the following random password:
rpcuser=xhimerarpc
rpcpassword=7Pp8KsNAXTqjSqhgGVWD6TaPiYrBtRJjh6qmqyT66npK
(you do not need to remember this password)
The username and password MUST NOT be the same.
If the file does not exist, create it with owner-readable-only file permissions.
It is also recommended to set alertnotify so you are notified of problems;
for example: alertnotify=echo %s | mail -s "XHimera Alert" admin@foo.com"
