Is "port hammering" a way for two stations each behind a firewall to connect? |
| 11:33 |
asciilifeform |
awt: if both behind nat, will take considerably longer than if only 1. but yes |

Or is it possibly needed in the case where one station is not behind a NAT (not sure what the direct term for this is) |

awt: it's compat. with the old format (but 'flag' can nao be 1, see 5.4.10.5 ) |
| 11:41 |
asciilifeform |
awt: but yes, hammer is for the situation where both sides know the other to be live (i.e. recently received broadcasts from one anuther) but each is trapped behind a nat |
| 11:42 |

addrcast, in such a case, supplies a usable ip but not a usable port |
| 11:42 |

to connect, they must play 'port roulette' until they simultaneously win. |

Ok. It seems the dream of lappy to lappy from cafe may soon be realized. |

asciilifeform: How can a station determine automatically whether or not to set FLAG to 1, or is it a manual configuration? |
| |
~ 50 minutes ~ |
| 12:43 |
asciilifeform |
awt: see 5.4.10.5 : flag=1 if station believes it is behind a nat |
| 12:54 |
awt |
Ok, so "originator believes" -> knob |

~ 17 minutes ~ |
