[syslog-ng] RE: Removal of forwarder hostname ??

[krishna y]

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
