| *** | dmr104 has joined #arpnetworks | [15:44] |
| dmr104 | hello
I am trying to create a bridge between 2 interfaces which will facilitate the transmission of dhcp broadcast messages. I am stuck. https://termbin.com/x6b2s | [15:45] |
| florz | dmr104: what does brctl show say? | [16:02] |
| ..... (idle for 24mn) | ||
| dmr104 | ridge0 8000.ee890ea31408 no enp4s0
I can't add the interface wlan1 to the bridge as the operation is not supported | [16:26] |
| florz | then that's probably because it's not four-address capable? | [16:33] |
| dmr104 | Address being link-local? | [16:35] |
| florz | nah, MAC
or rather, because it's a station interface, not a an ap interface? like, it's an interface that can't transmit frames with arbitrary source MACs | [16:35] |
| dmr104 | software interface modes (can always be added): * AP/VLAN * monitor
are supported on wlan1, which is a usb dongle | [16:37] |
| florz | well, yeah, but is it in AP mode? | [16:39] |
| dmr104 | actually no
I am using wlan1 is station mode to connect to a wifi router. does AP stand for access point mode, i.e. running a dhcpd server? | [16:39] |
| florz | AP means access point, yeah, but that doesn't have anything to do with DHCP | [16:41] |
| dmr104 | if i change to access point mode right now i think i will lose my connection
i suspected as much. What is the difference between AP and station mode | [16:41] |
| florz | the point is that a normal station mode client can only transmit frames from one MAC address, which is its own, which can't work with a bridge that is expected to forward frames with arbitrary source MAC addresses
if you want to connect your bridge to an AP via WiFi, you probably need a WDS connection or something, I don't really remember the details | [16:42] |
| dmr104 | is machine authentication code the basis of ARP? And how does ARP differ from a link local address?
sorry to ask so many questions. i am a bit rusty of recent years so a bridge can have more than 2 end points? | [16:44] |
| florz | MAC == Media Access Control in this context, but that doesn't really mean anything anyway, at least not anymore
ARP isn't an address but a protocol and a bridge doesn't so much have endpoint as it has links, and of those it can have an arbitrary number | [16:48] |
| dmr104 | thanks. i will read some cisco stuff about WDS | [16:53] |

| I will run hostapd on the machine with the bridge. the only thing that confuses me is, will it connect to the wireless router still without any modification to the settings on the router? | [17:38] | |
| florz | no, you'll need to establish a WDS link | [17:48] |
