Re: [Babel-users] able to ping to neighbor but no entry in routing table

Hi, As suggested by you, we configured /32 routes for ad-hoc network. Raspberry pi's (both edge and non-edge systems) are able to connect to each other, but now even with the same configurations on my laptop I am not able to connect to that network. As soon as I start babeld on my laptop,

Are there any known issues with babeld for larger networks (10 machines)? There are known issues with 1 nodes. 1500 works fine. -- Juliusz ___ Babel-users mailing list Babel-users@lists.alioth.debian.org

Hi, We have setup a cluster of machines in a large room (8000 sq ft). One of these machines is connected to ethernet (master) and all others (slaves) connect to each other using adhoc wifi network. We use babeld to maintain routing tables on top of wifi adhoc network (to achieve mesh like

an ip route (normal) and ip route (bad) would be helpful. knowing what kernel versions you are running would be rather helpful. During the routing cache elimination period (linux 3.3 through 3.8 I think), lots of routing bugs came to light. More recently some bugs were found and fixed in

We are using raspberry pi's model B for master and model A for all the other slaves. We are using branch rpi-3.6.y from https://github.com/raspberrypi/linux which has kernel version 3.6.11 Look like they already have a branch for kernel version 3.13 I can test this with the new kernel version.

We are facing an issue where all of a sudden the routing table is empty on the master as well as on the slave. Harshal, You are using Raspberry Pis, right? Some Raspberry Pis have a problem with the power supply, where the wifi interface will go down and back up when under load. Since Babel

Since we use model A for all slaves, the only way to get into the Pi is through the wifi interface. Hence I am not sure if it is babel or the interface or the Pi itself that is going down. But yesterday when this issue occurred, I was already remotely logged in to the master and one of the
