ArchiFleKsHi, this may sound like a trivial question but do you have more information about how nova and neutron dns worked together, I'm using neutron as a dns server, which work fine, I can have instances with .openstacklocal domain or a custom domain, but on ths instances itself, the hostname always get sets to novalocal anyway, is that a behavior that will change ultimatly ? If I set dhcp_domain to an10:37
ArchiFleKsempty string in nova, will it solve this ?10:37

jlibosvaslaweq: isn't it the same?13:11
slaweqnot exactly13:11
slaweq"-c" will stop tcpdump process after receiving specified number of packets13:12
*** Smeared_Beard has joined #openstack-neutron13:12
jlibosvabut they need to match the filter, no?13:12
slaweqand second solution would be to not match packets from tcpdump's stdout like it is done now but to search line "X packets received by filter" only13:12
slaweqin this line there are packets which match filter given in tcpdump command (so marked with specified dscp mark)13:13
*** b_bezak has joined #openstack-neutron13:13
jlibosvaslaweq: you could implement the source and dst ip adresses directly to the filter avoiding parsing the output13:13
slaweqjlibosva: yes13:14
*** SmearedBeard has quit IRC13:14
slaweqjlibosva: that's what I want to do in this "second proposed" solution13:14
slaweqmake more strict filter and check only if there were packets matching it :)13:14
slaweqI will propose a patch and we can then discuss it in review if needed, ok for You?13:15
jlibosvaslaweq: it's ok for me as you wrote it :)13:15
jlibosvaslaweq: I think that's a good idea13:15

morsikdoes anybody knows why Designate needs to have specified custom segmentation_id when integrating it with Neutron?13:38
morsikThis looks terrible when someone wants to automate stuff with Heat, cause those numbers could overlap13:38
morsikAnd default policy says that user can not set custom segmentation_id (what doesn't surprises me…)13:39

mwynneHi guys. I've been reading the Neutron release notes for Pike, and was curious about the rational behind proactively creating FIP namespaces and consuming public IP addresses. Does anyone know why this was done? I must be missing something to explain this change.20:47

SamYaplemwynne: i can not explain the reasoning, im sure there is more insight in the actual patch. my guess would be creating them on the fly creates issues with running out of ip address and how to handle that since that would bork networking, but nova has no way to be aware fo that21:47
SamYaplei would suggest finding the PS or commit and getting more info on that21:48
haleybmwynne: see https://docs.openstack.org/ocata/networking-guide/config-service-subnets.html - those ports don't need to consume public IPs21:50
*** slaweq_ has joined #openstack-neutron21:50
mwynnehaleyb: Yeah, I've seen that. I know there's a workaround, but it seemed like a strange decision to force this as the new default and give workarounds for those who don't want this new configuration.21:50
SamYaplei took the question to be more *why* than workaround21:51
mwynneYeah, I'm curious as to why this change was made, rather than a config setting or something to enable this behaviour.21:53
haleybmwynne: with dvr you could have one public IP consumed per compute node as soon as a VM associates one, so we had to have a way around that21:53
*** esberglu has quit IRC21:54
haleybi believe the change was made since there were a number of race conditions, but you'd have to point me at the change you found21:54
*** slaweq_ has quit IRC21:54
mwynnehaleyb: I haven't found a specific change. I just saw the note addressing this in the release notes, and couldn't come up with a reasonable justification for this change in behaviour. More curiosity than anything.21:56
SamYaplemwynne: check the commit associated with the release note21:56
SamYaplehopefully it was merged at the same time21:56

mwynneGood stuff. Thanks.22:01

mwynnehaleyb: Maybe this is a question for you: With dvr_snat, N/S traffic still needs to be routed through a network node. Why can't those SNATs live on compute nodes like FIPs? This came up in a discussion I was having regarding the new dvr_no_external agent mode.22:02

haleybmwynne: only default SNAT N/S traffic needs to go via the network node, and there are many reasons they are not distributed - don't want to have multiple tenants share an IP, migration of instance would change IP, ...22:08

mwynnehaleyb: what do you mean by 'only default SNAT N/S traffic needs to go via the network node'?22:11
*** markmcclain has joined #openstack-neutron22:11
mwynneAny outbound traffic needs to go to the network node unless there's a FIP associated with a VM's port, in which case it will use that, right?22:12
haleybmwynne: floating IP traffic is via the compute node directly if it's on an external network22:12
*** rcernin has joined #openstack-neutron22:12
haleybfor most internet-facing instances, the default SNAT IP is only used during boot, then a floating is associated22:13
mwynnehaleyb: If you have a VM which needs internet access, but not a FIP/DNAT, wouldn't it make sense to have that traffic SNAT'd on the compute node, and sent out br-ex at that point, which would reduce the amount of traffic the network node has to process?22:14

haleyband consume another public IP?  there is another way using address scopes, https://docs.openstack.org/ocata/networking-guide/config-address-scopes.html22:21
haleybif you can control *all* the addresses then there would be no NAT22:22
mwynnehaleyb: The snats on the network node are already consuming public IPs. Why not move those to the compute node?22:22
*** jose-phillips has quit IRC22:22
haleybbecause we can't have tenants sharing those IPs, plus we do support l3-ha22:23
mwynneThat's true. Thanks for the info :)22:24
haleybwe've though about it many times, and using address scopes is about as close as you'll get to not using the snat namespace22:25
