Hi, I'm experiencing strange issue with syslog-ng 2.0.5 build on a CentOS4 machine. One of a logging hosts receives after syslog message a ICMP port unreachable message sent from machine running syslog-ng. Other hosts logging is working fine. The only difference between logging hosts and this single not logging host is a little bit faster logging rate. Aprox. 10 log records/s. Debug option did not show something interesting why the syslog's are not being accepted. There is no firewall/filtering on the log server. Here is my simple config: options { use_fqdn(no); use_dns(persist_only); dns_cache_hosts(/etc/hosts); keep_hostname(yes); long_hostnames(off); sync(1); log_fifo_size(1024); perm(0640); }; source src { udp(ip("0.0.0.0") port(514) so_rcvbuf(4194304) ); tcp(ip("0.0.0.0") port(514)); }; source self { internal(); }; destination central {file("/var/log/central/$HOST_FROM.log"); }; destination self {file("/var/log/central/syslog-ng.log"); }; log { source(src); destination(central); }; log { source(self); destination(self); }; netstat -su output: 20578970 packets to unknown port received. 464 packet receive errors 190828 packets sent Does anyone have some idea how to deal with it? -- Karel
