Hi, thank you for your answer! I already tried this,but the connection still does not succecc for another reason... The "invalid hit" was ok again with the /ect/hip/hosts "spaces"-checking.I am not sure about the necessity of creating a new hi default for a recompiled kernel,is it? If I execute ./hipconf new hi default, I obtain a new hi and I have to update also the /etc/hip/hosts file in the other peer...Is that really necessary? Thank you again!
