Hi Mike, Thanks for ur reply. It's working now with the option spoof_source It requires libnet also to use this option while compilation. Installed libnet and used the following: ./configure --with-libnet=path_of_libnet-conf --enable-spoof-source Thanks for ur help, Krishna Y On Mon, 23 Jan 2006 Michael Gehrmann wrote :
Hi,
What you are looking for is a compiled option: --enable-spoof-source
You can then enable it in your syslog-ng.conf using the option per destination e.g. destination syslogbox { udp("X.X.X.X" port(514) spoof_source(yes)); };
Regards Mike

Hi,
I have configured the Syslog-ng in HPUX and forwarding the messages to Ciscoworks The original message to Syslog-NG is as following:
Jan 20 12:44:32 SYSNG.it.net CiscoDev01 7366: Jan 20 12:44:31.526 GMT: %SYS-5-CONFIG_I: Configured from 192.168.100.10 by snmp
While forwarding to other syslog server, Syslog-NG is adding it's own host name to the message and sending as below:
Jan 20 12:44:32 SYSNG.it.net CiscoDev01 7366: Jan 20 12:44:31.526 GMT: %SYS-5-CONFIG_I: Configured from 192.168.100.10 by snmp
(Note:SYSNG.it.net = HostName of Syslog-ng server, CiscoDev01=Device hostName)
The final syslog Server(Ciscoworks) is not treating the message is as from the CiscoDev01.There's no use of running script in Ciscoworks box to remove the entry of SYSNG.it.net. It has to be done before receiving the message
How to avoid this at Syslog-NG level? Tried the following options, but no luck: keep_hostname(yes); chain_hostnames(no); long_hostnames(no);
Please let me know the procedure not to append the hostname of the Syslog-NG to the message.
Thanks in advance, Krishna Y
