[B.A.T.M.A.N.] batman-exp rev.1154 still using 94% CPU load
by Stephan Enderlein (Freifunk Dresden)
Hi,
I have still the problem that batman-exp is hanging on 94% cpu load.
perhaps it has nothing to do with the gateway task. It is possible that
I run more "batmand -c" at same time?
The current batman revision is 1154.
Do you have any idea?

Re: [B.A.T.M.A.N.] Some questions to BATMAN
by John Harris
Hii Don,
my scenario look like as follows...
router 1 <---------------------> router 2 <-----------------------> router 3 (connected to server..IP 129.211.186.46)
eth1:bat eth1:bat eth1:bat (11.1.1.2) (wired: 129.211.186.12)
The IP Adress of my router 3 is 129.211.186.12 (dhcp-lan), router 3 is connected to my server with the server IP 129.211.186.46.
I can ping the eth1:bat interface of the router among each other. But I couldn't make a trace to the server IP 129.211.186.46 from
an another router... I get the message:
" *sendto: Network is unreachable
traceroute: wrote 129.211.186.46 40 chars, ret=-1"
My settings to BATMAN are:
----------------------------------------
Management: B.A.T.M.A.N.
WLAN as 11.1.1.3/24
LAN as 129.211.186.12
local internet-bandwidth: This is not a internet-gateway
common used gateway stable
Prefered gateway:
Host&Network Announcement (HNA): 129.211.186.46/24
Visualisation Server:
Hello-Interval [ms]:
----------------------------------------
The output of the command "batmand -c -d 1" on the router I see:
Originator Router (#/128): Potential routers... [B.A.T.M.A.N. 0.2 rv502, MainIF/IP: eth1:bat 11.1.1.1, UT: 0d 1h22m]

I would be very appreciate, if you an the others could give me some advice how to fix my problem...How can make a
traceroute form a router to the server IP 129.211.186.46.
Thanks in advance...

[B.A.T.M.A.N.] Some questions to BATMAN
by John Harris
Hiii,
I have some question about BATMAN routing protocol...
I would be appreciate if anybody could help me...
1)
I will build a mesh network.. One of my router is connected to my server with the IP 129.211.186.12. I can't make
a traceroute through my router to this server. If I try to make "traceroute 129.211.186.12" from an another router I get the message:
"PING 129.211.186.12 (129.211.186.12): 56 data bytes
ping: sendto: Network is unreachable
"
I can send ping requests from my server to the router and from the router to the server, but as I said, I can't make a traceroute to the server
from an another router. My question is, how can I do this ?
In OLSR it was not a problem to trace the server through the router. Should I change something in HNA messages ?
2)
I read the HowTO from Freifunk Leipzig about the configuration of BATMAN, look here http://wiki.leipzig.freifunk.net/BATMAN. How is the configuration
If I want to run BATMAN in Ubuntu Intrepid? How can I configure the IPTABLES ?
greetings,
John

[B.A.T.M.A.N.] batman advanced 0.1 release
by Marek Lindner
Hi,
today, after a 6 months stabilization and debugging phase we release the first
milestone towards a stable version: batman advanced 0.1.
As this implementation resides in the kernel land only we wanted to make sure
its stability before releasing it to the public.
This batman implemention is marked with the label "advanced" to outline the
fact that it operates on layer 2 (mac layer) as opposed to batman which
operates on layer 3. To gain optimal performance it resides in the kernel as a
module and can be enabled/disabled/configured via the /proc/net/batman-adv/
interface.
Unfortunately, we can not offer precompiled packages for your kernel as the
module sources need to be linked against your very own kernel headers. If you
are using debian you will find packages that you can install via apt-get.
OpenWRT also has the package included. If you intend to use the module on your
own system, simply download the sources, build and load the module.
You can find the sources here:
http://downloads.open-mesh.net/batman/stable/sources/
Special thanks to Sven Eckelmann and Scott Raynel who spent a considerable
amount of time testing, debugging and patching the sources. We included all
their patches which allow us to release today.
The biggest changes since the beta release are:
- support latest kernel version (2.6.20 - 2.6.28)
- LOTS of cleanup: locking, stack usage, memory leaks
- Change Ethertype from 0x0842 to 0x4305

[B.A.T.M.A.N.] [PATCH] Split SOURCE_VERSION in RELEASE- AND EXTRA_VERSION
by Sven Eckelmann
RELEASE_VERSION and EXTRA_VERSION can be concatenate to a single
SOURCE_VERSION string. This makes it possible to detect unstable
versions during compile time instead of removing the unstable warning
in a seperate commit (or forget this change).
Before releasing the a new stable version the release manager must set
EXTRA_VERSION to "", check INSTALL, THANKS and README and then create
the tag in the repository.
Afterwards the development branch should change the RELEASE_VERSION to
the upcoming version number and the EXTRA_VERSION to a string which
informs the user that it is "unstable" and in development. This could be
for example "-dev", "-pre-alpha", "-beta" or "-rc1".

[B.A.T.M.A.N.] [PATCH] Make batman timer functions thread safe
by Sven Eckelmann
The calculation inside of update_internal_clock aren't atomic and can lead to
bogus time informations when many threads calling get_time_msec64 or
get_time_msec.
