Hello!
[1.] One line summary of the problem:
/proc/sys/net/ipv4/ip_dynaddr does not work correctly in debug-mode.
[2.] Full description of the problem/report:
I've recognized that the debug-mode ("2") with
/proc/sys/net/ipv4/ip_dynaddr does not work correctly. In fact, if I do
a "echo 2 > /proc/sys/net/ipv4/ip_dynaddr", nothing happens. There are no
messages in the syslog, and there is no function of ip_dynaddr at all.
If I use "echo 1 > /proc/sys/net/ipv4/ip_dynaddr", it works fine, of
course without any debugging messages.
So it seems that the "2"-mode (debug output) does not work correctly
with newer kernels (tested with 2.4.21 and 2.4.24)
