Comment 1 for bug 802191

Hi Michael,

That's normal on systems with only plain sudo available. On startup Haguichi checks if the configured sudo command is still available by running "{configured sudo command} --help". Because sudo (unlike gksudo, gnomesu, kdesudo, etc) doesn't have the option --help, it's displaying the "invalid option" message.

Please be aware that without graphical sudo command on your system (i.e. Fedora), you need to set up the right permissions to start and stop the hamachi deamon in advance.
