[Click] Help FromHost!!

[María Gómez]

This is my configuration:

//this file generates UDP traffic

RatedSource(DATA \<55 44 50 20  70 61 63 6b  65 74 21 0a  04 00 00 00  01 00 00 00

    -> c::Counter    
    -> SetTimestamp        
    //-> StoreTimestamp(TAIL true)
    -> DynamicUDPIPEncap(1.0.0.1, 1234, 2.0.0.2, 1234, INTERVAL 10)      //header IP= 20 + header UDP= 8
    -> SetUDPChecksum    
    -> SetIPChecksum    
    -> EtherEncap(0x0800, 1:1:1:1:1:1, 2:2:2:2:2:2)                //header eth = 14
    -> Print ("source")                                                             // packet length 114
    -> c2::Counter    
    -> cola::Queue()                            
    -> l::LinkUnqueue (0, 512 kbps)                
    -> Queue    
    -> c3::Counter
    -> ToDevice(tun0)


//the other file

FromHost(tun0)
    -> Queue
    -> l1::LinkUnqueue(0.16, 512 kbps)            //link
    -> Queue    
    -> c::Counter        
    -> SetTimestamp    
    -> Unqueue
    -> brs::BandwidthRatedSplitter(1000 bps)    
    -> ToDump(tiempo1.dump, ENCAP IP)        
    -> Print    
    //-> Print("tasa menor de 1000 bps")
    //-> CheckIPHeader2    
    //-> Strip(14)                        //IPV4
    -> GetIPAddress(16)                
    -> DropBroadcasts        
    //-> CheckUDPHeader    
    //-> StripIPHeader()    
    -> DecIPTTL                    
    //-> IPPrint("hola",PAYLOAD hex, ID true, TTL true, LENGTH true)//OUTFILE dump_packets)        
    -> DynamicUDPIPEncap(2.0.0.2, 1234, 1.0.0.1, 1234, INTERVAL 10)      
    -> EtherEncap(0x0800, 2:2:2:2:2:2, 1:1:1:1:1:1)                    
    -> Queue
    ->l2::LinkUnqueue(0.16, 512 kbps)            //link
    -> Queue
    -> ToDevice(tun1)

brs[1]-> Print("tasa mayor de 1000 bps") -> IPPrint("hola",PAYLOAD hex, ID true, TTL true, LENGTH true)    -> d1::Discard;


Although the second file has only FromHost(), Print() and Discard, the console output is 110 bytes.

Thank for your time
