| Summary | 0003866: local peer discovery should be implemented | ||||
| Description | Ideally by announcing and querying using different mDNS backends like bonjour/apple?, android?/binder, avahi/dbus, mdns/ubus, ... Another way might be to use UDPv6 link-local multicast directly on-top of Ethernet-like media. | ||||

|
We do use UPDv6 multicast, and UDPv4 broadcast for local discovery already. |
|
|
I see, looking at the code it seems sufficient. It would be nice to allow configuring the specific interface to use for multicast/broadcast as well as adding/removing interfaces during runtime. |

|
Is this issue fixed already? |
|
|
I've found an issue in the UDPv4 broadcast for discovery: In case the udp communicator does not disable ipv6, it will bind the `default_udp_sock` to an ipv6 address. That will cause a failure when trying to send a broadcast packet to an ipv4 broadcast address. So it's probably necessary to always have another default socket around for ipv4 traffic (bound to an ipv4 address) or using a raw socket for both protocols. Issue is pretty much in gnunet-communicator-udp.c line 3341. So currently the UDPv4 broadcast only works when disabling ipv6 for the communicator. |

|
The issue with UDPv4 broadcast should be fixed with commit b3edc7b2ad04d09d84b06367b6c38c60ceebb33e now. |

|
Isnt this already fixed? |
|
|
This is fixed (at least as feature) since we introduced TNG. Any remaining bugs may go into new issues. |
