[ibr-dtn] tests with IBRDTN 0.10.2

Hello, I'm trying to test the IBRDTN version 0.10.2 in 3 computers, sending from PC1 to PC3, through PC2 but i am having some problems. - I installed the software in all the three PC's- Connnected the PC1 and PC2 with a network cable- Started the deamons in both with "dtnd -i <port>"(it not appeared the info that the "deamon is ready")- After tried to do ping between the two PC's and it didn't work. Can you help me how can i solve this problem?and where i can get the information(commands that i need to use) about how can I send some bundle between PC1 and PC3 through PC2?

Thank you in advance,Luis Guedes
