fine, i'm not familiar with selinux,
but for a new Analysis-Farm we should build up, it's the default with

SELINUX=enforcing
SELINUXTYPE=targeted

And one more detail, i've got the problem on my new separate server,
if i want to execute the cgi's

e.g.
hobbit-nkview.sh
bb-findhost.sh
.
....and so on ...

error-messages in /var/log/audit/audit.log

Also, if i want to see the cpu-graph etc.....

type=AVC msg=audit(1203960082.238:51): avc:  denied  { execute_no_trans } for  pid=2217 comm="httpd" path="/usr/lib/hobbit/cgi-bin/bb-hostsvc.sh"

While, if i disabled selinux, i haven't got that problem ..


But maybe it's my own failure in the configuration or setup ..

If the messages are told you something, i will be lucky to hear an advice ..
Besides, i will look rather into my own configuration once more ...

Thanks & Cheers,
