Hello Jordi,
Thank you for the really quick response.
Quoting Jordi Sanfeliu <jo...@fibranet.cat>:
As you can see I don't have the 'Idrop' column in my output, and that's
probably is the definitive cause of the problem.
This is the version I have used:
$ uname -a
FreeBSD freebsd.fibranet.lan 7.2-RELEASE FreeBSD 7.2-RELEASE #0: Fri May
1 08:49:13 UTC 2009
r...@walker.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC i386
Sorry, I should have indicated what version of FreeBSD I am running.
My system is running 8.2-RELEASE, which is the latest stable version.
I did a bit of investigation myself. I happen to have 2 other FreeBSD
systems, one running 7.2-RELEASE (same as your version) and the other
running 8.1-RELEASE. The one running 7.2-RELEASE gives the same
results for "netstat -nibd" as your output - no 'Idrop' column. The
8.1-RELEASE one has the 'Idrop' column.
I cannot find anything about this change from either the release notes
for FreeBSD 8.0, 8.1 or /usr/src/UPDATING (which is usually where
important changes in versions are noted), but based on this post :
http://lists.xymon.com/archive/2011-February/030722.html
it appears that the format of the "netstat -i" output changed in
FreeBSD 8 to include that 'Idrop' column.
So, perhaps an easy way to fix this is to use different code to
process the output for netstat -nibd based on the version of FreeBSD
used? I've attached a patch which seems to do the trick for me.
Best Regards,
Sean
