[syslog-ng]$HOST trouble.

Hi. I did a simple setup of syslog-ng 1.4.10 to log all remote messages based on hostname/facility.priority.: source s_udp { udp(); }; destination d_all { file("/var/logng/$HOST/$FACILITY.$PRIORITY"); }; log { source(s_sys) ; source(s_udp) ; destination(d_all); }; The problem is that when some progs log in non-stnadart format , I get a directory structure that looks like:

ls Thanks ?<Quantum ?<Sony ?Cmd ?Disconnected ?Generic ?Rev. ?SCSI ?pkt_flags=0x0 ?pkt_scbp=0x0 > CU Copyright Covered In Other San _

and inside there will be a file with correct facility.priority name containing the remaining part of a message. Is there any way to use IP address of a source with DNS lookups , and not what source computers sends in a log message?
