Subject: [B.A.T.M.A.N.] Strange sequence numbers
Date: Sun, 14 Mar 2010 00:35:50 +0000 [thread overview]
Message-ID: <1268526950.4592.32.camel@rover> (raw)
I've been lurking on this list for a few weeks, but finally tried
compiling and running the batman-adv module from the svn sources.
It seems to work fine between my two test machines so far, but I noticed
some weird sequence numbers when doing a dump with 'batctl td'. In the
sequence below, I had 'rover' running and active on rover's eth0, then I
activated the eth1 interface on hilltop for a few seconds, then
de-activated it.
It seems like when rover re-sends the OGM from hilltop, it gets the
sequence number wrong (1->256, 2->512, 3->768). Is this my lack of
understanding of how it should work, a bug in batctl's display or a bug
in batman-adv?
rover is kernel 2.6.31-20-generic (Ubuntu karmic),
hilltop is kernel 2.6.26-2-686 (Debian lenny)
