[syslog-ng] Server conf for syslog-ng.conf

Hi, Can somebody show to me a sample to set-up for server of syslog-ng.conf? I'm trying to use this config but its complaining on s_network: @version:3.0 options { time_reap(30); mark_freq(10); keep_hostname(yes); }; source s_local { unix-stream("/dev/log"); internal();}; source s_network { syslog(transport(tcp))}; destination d_logs { file( "/var/log/syslog-ng/logs.txt" owner("root") group("root") perm(0777) ); }; log { source(s_local); source(s_network); destination(d_logs); }; What Im missing here? Thanks and regards, Agustin Lozada UNIX System Admin 713-207-2474
