initial commit

 This is a standalone version of systemd-netlogd, extracted from the
systemd repository as of commit ID 13317a2

 This daemon Forwards messages from the journal to other hosts over the
network using the Syslog Protocol (RFC 5424). It can be configured to
send messages to both unicast and multicast addresses. systemd-netlogd
runs with own user systemd-journal-netlog. Starts sending logs when
network is up and stops sending as soon as network is down ( uses sd-network).
Actually useful beyond the scope of systemd itself.

+systemd-netlogd
+===================
+
+Forwards messages from the journal to other hosts over the network using
+the Syslog Protocol (RFC 5424). It can be configured to send messages to
+both unicast and multicast addresses. systemd-netlogd runs with own user
+systemd-journal-netlog.  Starts sending logs when network is up and stops

+
+Configuration
+-------------
+
+Create a user  **systemd-journal-netlog**
+> - useradd -G systemd-journal systemd-journal-netlog
+
+
+**[NETWORK]** SECTION OPTIONS
+
+
+       The "[Network]" section only applies for UDP multicast address and Port:
+
+       Address=
+           Controls whether log messages received by the systemd daemon shall be forwarded
+           to a unicast UDP address or multicast UDP network group in syslog RFC 5424 format.
+
+           The the address string format is similar to socket units. See systemd.socket(1)
+
+**EXAMPLE**
+
+ Example 1. /etc/systemd/systemd-netlogd.conf
+
+           [Network]
+           Address=239.0.0.1:6000
+
+Example 2. /etc/systemd/systemd-netlogd.conf
+
+           [Network]
+           Address=192.168.8.101:514
