Hi !
Is there any selinux-policy for hobbit available or can somebody point me to a solution for it .... ? .. beside to disable it :-)
I don't think a policy should be necessary in targeted mode, but chcon might need to be run with the right options to set the right context on the relevant directories/files.
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
Can you give the selinux error message you get ? And, how did you install Hobbit ?
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 ...

While, if i disabled selinux, i haven't got that problem ..
I assisted someone in setting up Hobbit on a system that had selinux enabled, and this was what I needed to do to get it to work correctly:
chcon -t httpd_sys_script_exec_t /usr/lib/hobbit/cgi-bin/* chcon -t httpd_sys_script_exec_t /usr/lib/hobbit/cgi-secure/* chcon -R -t httpd_sys_script_ro_t /var/lib/hobbit/rrd/
(besides usual file permissions issues).
I will try and see if I can ensure this isn't necessary (either setting the contexts during the package build, or in a postinstall script) for my own hobbit RPMS, if it works, I may make the packages available.
