Dropping Privileges After Startup
|
|
=================================
|
|
|
|
Currently, libcap-ng is needed for dropping privileges on Suricata
|
|
after startup. For libcap, see status of feature request number #276
|
|
-- Libcap support for dropping privileges.
|
|
|
|
Most distributions have ``libcap-ng`` in their repositories.
|
|
|
|
To download the current version of libcap-ng from upstream, see also
|
|
http://people.redhat.com/sgrubb/libcap-ng/ChangeLog
|
|
|
|
::
|
|
|
|
wget http://people.redhat.com/sgrubb/libcap-ng/libcap-ng-0.7.8.tar.gz
|
|
tar -xzvf libcap-ng-0.7.8.tar.gz
|
|
cd libcap-ng-0.7.8
|
|
./configure
|
|
make
|
|
make install
|
|
|
|
Download, configure, compile and install Suricata for your particular setup.
|
|
See :doc:`../install`. Depending on your environment, you may need to add the
|
|
--with-libpcap_ng-libraries and --with-libpcap_ng-includes options
|
|
during the configure step. e.g:
|
|
|
|
::
|
|
|
|
./configure --with-libcap_ng-libraries=/usr/local/lib \
|
|
--with-libcap_ng-includes=/usr/local/include
|
|
|
|
Now, when you run Suricata, tell it what user and/or group you want it
|
|
to run as after startup with the --user and --group options.
|
|
e.g. (this assumes a 'suri' user and group):
|
|
|
|
::
|
|
|
|
suricata -D -i eth0 --user=suri --group=suri
|
|
|
|
You will also want to make sure your user/group permissions are set so
|
|
suricata can still write to its log files which are usually located in
|
|
/var/log/suricata.
|
|
|
|
::
|
|
|
|
mkdir -p /var/log/suricata
|
|
chown -R root:suri /var/log/suricata
|
|
chmod -R 775 /var/log/suricata
|
