All of the syslog messages sent by our Solaris servers that contain output from the service processor are getting the wrong hostname assigned to them - the log messages get filed under the hostname of the receiving syslog-ng server. They all share the same process name "SC Alert". The packets look correctly formed so I am assuming it is the space in the process name. Any way to fix this without dropping the messages completely using something like bad_hostname? We are running 2.1.11a Enterprise Edition. Here is the relevant part of my syslog-ng.conf: options { sync (0); create_dirs (yes); keep_hostname (yes); check_hostname (yes); chain_hostnames (no); bad_hostname ("\t"); normalize_hostnames (yes); mark_freq (10); }; source src_net { udp(port(514)); }; destination d_hosts { file("/var/log/systems/$HOST_FROM/$FACILITY/$YEAR/$MONTH/$FACILITY\-$YEAR$MONTH$DAY" perm(0644) dir_perm(0755) create_dirs(yes)); ... log { source(src_net); destination(d_hosts); destination(d_splunk); flags(fallback); }; And here is an example packet from snoop.
