Not getting any info from linux system

I have tried to configure a linux host running on debian 3.1 stable without success.

I had tried while changing parameter in the file /etc/syslog.conf first.

Restarted the deamon

# CONFIGURATION LINUX OPENMANAGE
*.* @192.168.1.61

This wasn't working so:
# CONFIGURATION UNIX HP&CIE
*.emerg;*.alert;*.crit;*.err;*.warning;*.notice;*.info;*.debug @192.168.1.61

not working again...

So I moved to syslog-ng
apt-get install syslog-ng
(I had debugged the script file because of a error relating to kernel (/etc/init.d/syslog-ng)

case "x$CONSOLE_LOG_LEVEL" in
x[0-7])
dmesg -n $CONSOLE_LOG_LEVEL
;;
*)
echo "CONSOLE_LOG_LEVEL is of unaccepted value."
;;
esac

to

case "x$CONSOLE_LOG_LEVEL" in
x[0-7])
dmesg -n $CONSOLE_LOG_LEVEL
;;
x)
;;
*)
echo "CONSOLE_LOG_LEVEL is of unaccepted value."
;;
esac

2)case "x$KERNEL_RINGBUF_SIZE" in
x[0-9]*)
dmesg -s $KERNEL_RINGBUF_SIZE
;;
*)
echo "KERNEL_RINGBUF_SIZE is of unaccepted value."
;;
esac

to

case "x$KERNEL_RINGBUF_SIZE" in
x[0-9]*)
dmesg -s $KERNEL_RINGBUF_SIZE
;;
x)
;;
*)
echo "KERNEL_RINGBUF_SIZE is of unaccepted value."
;;
esac

After that syslog-ng started sucessfully. Good thing.

So I changed the configuration like you said:

destination eventloganalyser { udp("192.168.1.61" port(511)); };

log {
source(s_all);
destination(eventloganalyser); };

(My server is listening on 511)

Reloaded syslog-ng without problem

I'm not getting any date from theses linux but I can with all windows...

I don't think it's related to my linux because I have tried with Kiwi syslog and it was working very fine with the same parameter...

Any help will be appreciated

Thanks.
