Well, I'm starting to make progress. But something isn't right. I found
out the plugin error was due to the fact that despite syslog-ng.com
showing the reversal as NOT, the actual statement is not (all lower case
vs all upper case). So that means that syslog-ng loads just fine. But I
can't get the dhcp output to where I want it. If I have the syslog
facility in dhcpd turned on, or if I redirect the output to a file in
systemd, then I get dhcpd messages in the file AND in the syslog itself
(/var/log/messages). No matter what I try, the dhcpd output ALWAYS goes
to syslog. I can get it to go to a separate file TOO, but not ONLY.
Here's the entire syslog-ng.conf and the service file for dhcpd.
Hopefully you guys can figure something out I missed:
(dhcpd4.service)
[Unit]
Description=DHCPv4 Server Daemon
Documentation=man:dhcpd(8) man:dhcpd.conf(5)
After=network.target
After=time-sync.target
After=network-online.target
Wants=network-online.target
StandardOut=null
StandardError=null
[Service]
ExecStart=/usr/sbin/dhcpd -f -cf /etc/dhcp/dhcpd.conf -user dhcp -group
dhcp --no-pid
[Install]
WantedBy=multi-user.target
With everyhing going to null, you'd think that with the syslog statement
in dhcpd.conf disabled, I'd get no log at all. But I still get the log
in /var/log/messages. Here's syslog-ng.conf:
@version: 3.26
options {
threaded(yes);
chain_hostnames(no);
stats_freq(43200);
mark_freq(3600);
};
filter dhcpfilter { facility(local7); };
filter nondhcp { not filter(dhcpfilter); };
source src { system(); internal(); };
destination messages { file("/var/log/messages"); };
destination dhcplog { file("/var/log/dhcpd.log"); };
destination console_all { file("/dev/tty12"); };
log { source(src); filter(nondhcp); destination(messages); };
log { source(src); destination(console_all); };
log { source(src); filter(dhcpfilter); destination(dhcplog); };
And for what it's worth, here's my dhcpd.conf:
default-lease-time 3600;
max-lease-time 43200;
# Use this to enble / disable dynamic dns updates globally.
ddns-update-style interim;
authoritative;
# log-facility local7;

} else {
