I just noticed that syslogd is adding a hostname to the syslog messages it receives, whether there is one present or not. I'm probably missing the option, but is there a way to turn this off?
Example: Aug 13 19:17:01 dhcp.1.158.example.com beaglebone CRON[5529]: pam_unix(cron:session): session opened for user root by (uid=0) I'm fine with either dhcp.1.158.example.com or beaglebone being written to the log, but not both. I can probably configure some clients to not send a hostname when forwarding events, but not all of my clients are configurable. Any help would be greatly appreciated! rc.conf.local: syslogd_flags="${syslogd_flags} -u -a /var/unbound/dev/log" OpenBSD 5.8 (GENERIC.MP) #1235: Mon Aug 10 06:54:34 MDT 2015 dera...@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP real mem = 2120847360 (2022MB) avail mem = 2052739072 (1957MB) mpath0 at root scsibus0 at mpath0: 256 targets mainbus0 at root bios0 at mainbus0: SMBIOS rev. 2.6 @ 0x7f79c000 (62 entries) bios0: vendor Dell Inc. version "1.2.1" date 01/28/2010 bios0: Dell Inc.
