Hello, I have install syslog-ng on solaris 10(machine A],it configured as log proxy server more /etc/syslog-ng/syslog-ng.conf options { chain_hostnames(no); keep_hostname(yes); use_fqdn(yes); log_fifo_size(1000); }; source local { sun-stream("/dev/log"); udp(ip(0.0.0.0) port(514)); internal(); }; filter notdebug { level(info...emerg); }; destination ercmas13.eurocontrol.fr{ udp("ercmas13.eurocontrol.fr" port (514)); }; log { source(local); filter (notdebug); destination(ercmas13.eurocontrol.fr); }; A client (Machine C) on solaris 10 send logs on (Machine A) I say the log on ercmas13 (logs server) A client (Machine B) on redhat 4 send log on (Machine B) I have nothing on the log server I change this information in this files syslog-ng.conf on log proxy server Each possible communication mechanism has a corresponding source driver in syslog-ng. For example, to open a unix socket with SOCK_DGRAM style communication use the driver unix-dgram. The same socket using the SOCK_STREAM style - as used under Linux - is called unix-stream. source local { unix-stream("/dev/log"); udp(ip(0.0.0.0) port(514)); internal(); }; But when i restart le syslog-ng on log proxy server /etc/init.d/syslog-ng start syslog-ng service starting. Error binding socket; addr='AF_UNIX(/dev/log)', error='Address already in use (125)' Error initializing source driver; source='local' What is the problem ?
