i got this problem in my nagios...
but.. my .cfg is 0 for use_autenthication...
my daemon is OK
my nagios -v is OK, no error..
i guess that can be permission..
please.. can anyone look in yours files?
/usr/local/nagios/cgi (all files permissions)
in folder nagios, after into all files of folder nagios and folder rw, into the file nagios.cmd
i remember that i can change this.. i was trying to do changes by the web interface.. and its start with the erros..
Sorry Dave and.. bla bla bla..
after this error, came another with problem in /var/log/nagios/rw/nagios.cmd
and i change and change and... nothing work now..
anyone can help me?
