I have an rsyslog server which is running Debian Stable, and its version of rsyslog is 4.6.4-2. All of my Debian Stable server can send log to it now. and run both nc $IP $PORT <<< "HELLO" and echo "HELLO" | nc $IP $PORT on client, I can get log on the server. While for my CentOS 5.7 server, nc $IP $PORT <<< "HELLO" works well, but echo "HELLO" | nc $IP $PORT can not work. tcpdump shows that it can get both of the 2 "HELLO" from server. And I can not get log both by log file or tcpdump. *.* @@IP:PORT _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos
