[Click] Grid elements questions

[Sotiropoulos Georgios]

Hello,

I am just another Master student that recently started working with 
Click. Specifically I am interested in the grid elements. I have two 
questions:

1) I have set up grid routers in two laptops and tried to ping from one 
to another. For every packet received at the receiver I got message like 
(expensive packet::push (got 72 wanted 84?)). I cant understand what is 
the meaning of these messages. Does anyone have any idea?

2) I was trying to use the logging options that some grid elements 
support. Specifically, I tried to use a GridLogger for the 
DSDVRouteTable. As I have already mentioned, I have two laptops that are 
running the grid router and I tried to ping once again and look at the 
generated log file. Unfortunately everything that was written in the 
generated log file were some bizzare symbols. Does anyone have any idea 
what am I supposed to see?Or any info about log capabilities in the grid 
elements would suit me fine as well


Thank you in advance!
