You are right!

It is really caused by my firewall setting, I have solved it=20

The conf file has no error.=20

It works with udp() also.

Maybe your UDP port is closed (firewall ?) ....

I think you should use the following:

udp(ip(0.0.0.0) port(514));

=20

instead of udp();

Subject: [syslog-ng]Can't receive syslog by UDP protocol

Greeting!

=20

I have set up my syslog-ng environment by the default syslog-ng.conf =
file.
By the linux default logger command, I can generate syslog to file.=20

But when I use a syslog client send out syslog to the syslog-ng server, =
I
can=A1=AFt receive the log by UDP protocol. But I can get TCP protocol =
syslog.
Could anyone tell me why?

=20

Thanks!

=20

My system is RedHat 9.0. The syslog client is Kiwi Syslog Gen in =
windows.
The following is part of my syslog.conf file:

=20

source src {=20

         pipe("/proc/kmsg");=20

         unix-stream("/dev/log");=20

         internal();=20

         udp();

         tcp(port(5140) keep-alive(yes));=20

};

=20

log {=20

         source(src);=20

         destination(file);=20

};
