[syslog-ng]Unwanted logging

[BENGT OLSSON]

Hi

I get some unwanted loggin from strange hosts....

The syslog-ng.conf-file looks like;

options { use_fqdn(yes); keep_hostname(yes); use_dns(yes); 
long_hostnames(off); sync(0); log_fifo_size(1000); };
source all { sun-streams ("/dev/log" door("/etc/.syslog_door")); 
internal(); udp();  };
destination hosts { 
file("/var/syslog/hosts/$HOST/$FACILITY_$YEAR-$MONTH-$DAY" owner(root) 
group(root) perm(0600) dir_perm(0700) create_dirs(yes)); };
log { source(all) ;  destination(hosts) ; };

An example of unwanted "hosts"-directory in the /var/syslog/hosts-directory;
0x0.0x5da74da             
0x0.0x5dc3cea
0x0.0x5dc3d5a
0x0.0x5dc4077
0x0.0x5dca334
0x0.0x5dcea7a
0x0.0x637fb77
0x0.0x642bad8
0x0.0x64c5ea8

An example of correct hosts -directory in the 
/var/syslog/hosts-directory looks like this;
trillian.student.bth.se
trumma.bth.se
viking.student.bth.se
viola.bth.se
violin.bth.se
vogonjeltz.student.bth.se
voyager.student.bth.se
vroomfondel.student.bth.se
 zaphod.student.bth.se

Is there some internal logging or what is it comming from?

A minor problem is that i have  the "long_hostnames" to off and still it 
loging whit long hostnames....any guess?

Best Regards
