bern | hi everyone, I'm looking to use openvswitch to do stateful layer 2 filtering in Linux. Is there a write-up of this sort of thing for ebtables (or nftables) dummies like me? :) | 07:47 |

bern | flaviof: I have a had look there, and there's loads of great documentation, but it's a bit of a new way of thinking for me so I'm a little unsure where to start. I had already read, for example the FAQ which says "The OVS conntrack feature (see the “ct” action in ovs-actions(7)) can implement a stateful firewall", and I had looked at that man page, but it's a bit overwhelming. | 13:26 |
bern | I understand the concept of disaggregated control and data planes; I've got a background in both Linux and networking; I'm looking for a signpost where I can understand how the openflow tables work, and what sort of actions I can get away with inter-playing with the "normal" action, or whether I need to implement my own controller to do simple L2 filtering. | 13:30 |

flaviof | bern: this is a very vast field. Too many options. A humble suggestion, if what you want is to play with openflow: http://docs.openvswitch.org/en/latest/tutorials/faucet/ | 13:48 |
flaviof | bern: https://youtu.be/BztZSAcfEvY?t=30m44s | 13:49 |
flaviof | but there are many many many many other places you can go too. Take your time and enjoy | 13:49 |
bern | Thank you. I'm sure I'll get there! | 13:54 |
bern | Sounds like I'll need to use a controller for anything non-trivial. | 13:54 |
