Problem sending logs to central log server..

19 Sep 2011

      Hello, I'm trying to sent all my logs from one openbsd server with syslog-ng
to a linux ubuntu central log server also with syslog-ng of course but only
the syslog-ng logs are been logged..
also when I do a "logger test" for example it gets log locally but not
remotely to the log server...
here are my configs:

for the log server is basically the defaul of ubuntu with my addtions at the
end.. you will see
some commented is me trying to fix this issue.

cat syslog-ng/syslog-ng.conf
#
# Configuration file for syslog-ng under Debian
#
# attempts at reproducing default syslog behavior

# the standard syslog levels are (in descending order of priority):
# emerg alert crit err warning notice info debug
# the aliases "error", "panic", and "warn" are deprecated
# the "none" priority found in the original syslogd configuration is
# only used in internal messages created by syslogd

# options

        stats_freq(0);

        # Some program send log messages through a private implementation.
        # and sometimes that implementation is bad. If this happen syslog-ng
        # may recognise the program name as hostname. Whit this option
        # we tell the syslog-ng that if a hostname match this regexp than

        # is not a real hostname.
