Hi, 
 
I read the message from sosesca and it appears that I am currently meeting
exactly the same problem as her.
I am still trying to fix it
 unsuccessfully!
 
I tried Frank suggestion but by doing “lsd -j 127.0.0.1:10000 -l 127.0.0.1
-p 10000” the program seems to be lost in an infinite loop:
 
> lsd:  running with options:
> lsd:   IP/port: 107.0.0.1:10000
> lsd:   vnodes: 1
> lsd:   lookup_mode: 1
> lsd:   ss_mode: -1
>   1086316830:313230 9173f7cbbc4f426392eca75f3a45781d292f69c2: stabilize:
stable! Stabilize timer 1000
 
... and from here nothing happens then!
 
Your help would be welcome!
 
Sam
