Hi,
I run all my sensors with transparent mode set to off, but sometimes
it is necessary to switch to transparent mode to capture on the
management interface for troubleshooting. I wrote a simple script to
do this for our help staff. Since I set my modprobe options for ring.o
in modprobe.conf I test this file to see if transparent_mode is 1 or
0. This however is not a very good test of whether or not the module
is actually in transparent mode or not. This status should probably be
noted in /proc/net/pf_ring/info.
Attached is a patch that adds this info to /proc/net/pf_ring/info.
