[syslog-ng] syslog driver: IP instead of hostname

[Alexandre Santos]

Hello,

I have the following a syslog-ng server and a syslog-ng client, which
configurations I am sending in attachment.
I am using the syslog driver in order to have full compatibility with
RFC5424.
I want to use the IP address and not the hostname, but I keep seeing the
hostname in tcpdump:

[root at tests tests]#  tcpdump -A -i virbr0 port 60514 or 514
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on virbr0, link-type EN10MB (Ethernet), capture size 262144 bytes
18:30:09.810757 IP 192.168.122.11.34512 > tests.syslog: SYSLOG local0.info,
length: 100
E..... at .@..K..z...z......l..<134>1 2020-02-26T18:30:09+00:00 localhost root
9519 - - This is a local0 info buffer filler string

and in logfile:

<134>1 2020-02-26T18:30:09+00:00 localhost root 9519 - - This is a local0
info buffer filler string

Can you help me?

Thanks in advance,
Alex
