I changed the Software package rsyslog to syslog-ng and also the configuration from the /etc/syslog-ng/syslog-ng.conf file:

apt-get autoremove rsyslog

dpkg –P rsyslog

apt-get install syslog-ng.

change the configuration at the configfile:

/etc/syslog-ng/syslog-ng.conf

Put in:

source s_udp { udp( ip(192.168.81.200) port(514) ); };

destination d_exflutcaX { file("/var/log/exfl/utcaX.log"); };

log { source(s_udp); destination(d_exflutcaX); };
