Would some kind soul tell me how to determine this?

I'd like to run ulogd on White Russion/RC5, and I'm getting these errors when I do:

ipulog_read == -1! ipulog_errno == 7, errno = 132

From /usr/src/linux-2.6.12/include/asm-mips/errno.h:

#define ENOBUFS         132     /* No buffer space available */

I realize the OpenWrt firmware runs 2.4.30 and not 2.6.12, but I guessed that these numbers remained the same.

And I found this with google:

https://lists.gnumonks.org/pipermail/ul … 00308.html

which seems to address my problem too (though the errno is different, the ENOBUFS is the same)

So rather than just going with the defaults from ulogd.conf, I thought I would adjust them to fit the OpenWrt firmware (in case it's different than a stock kernel) or at least figure out what these numbers are for the OpenWrt firmware before adjusting /proc/sys/net/core/rmem_*

Thanks for any replies.

For anyone else who might be interested in this issue (and tho this might have been the hard way to answer the question) I checked out the sources for whiterussion with svn and built the firmware myself, thus getting a copy of the kernel sources.  From there, I checked ipt_ULOG.c and found the answer to be 4096.

Sorry for asking half a year later: 4096 was the answer, but did it solve the problem? If I set rmem=4096 in ulogd.conf, I get a TON of these errno=132 messages, a lot more than with the standard settings. My router hangs after a few minutes or hours an I can only unplug the power cable.
