<div>So, and want to ask something completely differently, didn't want to make another email topic. </div><div><br></div><div>Can the rate control algorithm (sample, onoe, minstrel...) influence somehow in the way the costs are calculated in a node?</div>
<div><br></div><div>I have a really weird problem with 4 radios. </div><div><br></div><div><font class="Apple-style-span" face="'courier new', monospace">A -> B >- D</font></div><div><font class="Apple-style-span" face="'courier new', monospace"> \> C >/</font></div>
<div><font class="Apple-style-span" face="'courier new', monospace"><br></font></div><meta http-equiv="content-type" content="text/html; charset=utf-8"><div>They are arranged such that for a message go from radio A to D, it has to choose between C and B. So I have variable attenuators between A and B , and between A and C, it's all wireless confined in coaxial cable.</div>
<div><br></div><div>The idea is that the attenuator to B is adjusted such that it's worst than C, and I can get some throughput like 18Mbps. The path through C give me some throughput like 30 Mbps. </div><div><br></div>
<div>My problem is that, using minstrel, if I make some big attenuation between A and C, it cannot see C as 1 hop anymore, and the OLSR chooses to use the A-B-D path (i'm using Henning watch+txtinfo), it takes like 10 seconds or less (HelloInterval 1.0, HelloValidityTime 6.0), and I have 18Mbps throughput. The problem is that, when I adjust the attenuator back where it was when I had 30Mbps, the throughput stays in 18Mbps and path selected by OLSR remains A-B-D, even though it's much better to use A-C-D. Actually, it takes around 8 minutes so the radios notice the other path is clear - because I'm using txtinfo, I see it takes like seconds to readd C in the one hop list - and re-route using A-C-D, giving me back 30Mbps of rate.</div>
<div><br></div><div>Any thoughts?</div><div><br></div><div>The same path changing occurred really fast in both ways before, when I was using rate_sample instead of minstrel, but the overall rate was lower - 12Mbps A-B-D, and 24Mbps A-C-D.</div>

<div>Nevermind, found out there was some other older olsrd, probably from apt-get tool, inside the /usr/local/sbin. Just removed it with rm /usr/local/sbin/olsrd and now everything works. </div><br clear="all">Érico V. Porto<div>

<div>Hello Guys,</div><div><br></div><div>I have a small network in my desk that has two small radios running some tiny freescale linux version and a netbook running gentoo and my desktop runs ubuntu. Uname -a output is: Linux 050278 2.6.38-11-generic #48-Ubuntu SMP Fri Jul 29 19:05:14 UTC 2011 i686 i686 i386 GNU/Linux</div>
<div><br></div><div>I've sucessfully compiled the source for ppc -for the radios - and also for x86 - for my netbook. Surprisingly my desktop doesn't run olsrd! I'm trying to run the same object code that runs ok on the netbook, but without success. I'm getting the error : </div>
<div><br></div><div><div>ERROR(plugins) src/plugin_loader.c 287: DL loading failed: "/usr/lib/olsrd_txtinfo.so.0.1: undefined symbol: gateway_tree"!</div></div><div><br></div><div>Any thoughts on how to solve this?</div>
<div><br></div><div>The source was download from a link in this mailing list, it's 0.6.2 version. On ubuntu I installed using make && make install && make install_libs , after running a make uberclean.</div>
