Hi
First, thanks everyone for the help. I was obviously looking for
errors in the wrong place. If someone runs an MN on debian 5.0 kernel
2.6.26-1, please tell me how.
It works ok over a tunnel interface after some trouble.
When mip6d (umip from natisbad.org) is configured with a tunnel
interface it sometimes segfaults on start leaving ip6tnl-devices up
etc...
After setting ulimit to unlimited I can't get it to segfault so no core file. :(
Config on MN is:
NodeConfig MN;
DebugLevel 10;
DoRouteOptimizationCN disabled;
DoRouteOptimizationMN disabled;
UseCnBuAck enabled;
MnDiscardHaParamProb enabled;
Interface "tunnel" {
Tunnel enabled;
}
MnRouterProbes 1;
MnHomeLink "tunnel" {
HomeAddress xxxx:xxxx:0:1300::1/32;
HomeAgentAddress xxxx:xxxx::1;
}
UseMnHaIPsec disabled;
KeyMngMobCapability disabled;
Output is:
