* - own address (if peer is behind a nat/router)

* - check peer type (virgin/junior/senior/principal)
|
|
*
|
|
* to do this, we send a 'Hello' to another peer
|
|
* this carries the following information:
|
|
* 'iam' - own hash
|
|
* 'youare' - remote hash, to verify that we are correct
|
|
* 'key' - a session key that the remote peer may use to answer
|
|
* and the own seed string
|
|
* we expect the following information to be send back:
|
|
* - 'yourip' the ip of the connection peer (we)
|
|
* - 'yourtype' the type of this peer that the other peer checked by asking for a specific word
|
|
* and the remote seed string
|
|
*
|
|
* one exceptional failure case is when we know the other's peers hash, the other peers responds correctly
|
|
* but they appear to be another peer by comparisment of the other peer's hash
|
|
* this works of course only if we know the other peer's hash.
