13:14<@jcardillo>gustavo: we provide support regardless of the plan you're on. it's just that internal configuration questions are outside the scope of what we can assist with, since we don't have access to your server.
13:15<@jcardillo>the scope of our support is outlined in section 6 of our terms of service:

14:29<heckler>I have a webserver instance and a database instance, each has a public and a private ip bound to eth0 on centos 7. I want to connect these via the private IPs, with firewall rules to only allow the webserver access to the db. Is this going to work with firewalld zones or do I need to set up a virtual interface like eth0:1 and assign that to a different zone?
14:29<heckler>or, what is the easiest way to do this?
14:39<retro|blah>I don't think you can assign "virtual interfaces" to different zones. Consider matching by source and/or destination IP addresses instead.
14:49<heckler>ok, but that means both IPs are on the same interface in the same zone, with different rules, that seems kind of strange to me.
14:53<retro|blah>You might consider that your Linode's private IPs are accessible from all other Linode private IPs in the same datacenter, whether those other Linodes are yours or not.
14:55<retro|blah>Having said that... Perhaps it's possible to add source IPs to zones, as opposed to interfaces?
14:57-!-RedFacedGInger [~oftc-webi@12.186.149.251] has quit [Remote host closed the connection]
14:58<heckler>retro|blah: yes, I have considered that. The plan is to only accept connections on the private IP from the source of my webserver
15:00<heckler>retro|blah: but if both IP are on the same interface, and only one zone per interface, that seems like a problem because the rules for the private IP would apply to the public IP as well. So i guess I would have to be able to add a rule to allow me to ssh into the box directly from outside.
15:01<retro|blah>Did you see my comment about "possible to add source IPs to zones, as opposed to interfaces?"
15:01<millisa>you could use another zone - the work zone is predefined - put your private ip's there with whatever openings are appropriate. the more specific zone takes precedence
15:02<heckler>millisa: but i thought only one zone per interface
15:02<millisa>why do you think that?
15:02<heckler>can i have more than one zone per interface?
15:03<heckler>i guess i have a lot of reading to do on this subject again.
15:04<heckler>i meant active zones, of course.
15:05<millisa>this is a copy of one of my firewall-cmd --list-all-zones outputs: https://vomitb.in/9xvuz3NPvt (a few bits redacted)
15:06<millisa>(I'm connected from that range in the mycustomzonename)
15:10<heckler>mycustomzonename doesn't have an interface associated?
15:13<millisa>nope
15:14<heckler>ok i guess i will spend a few days reading
15:14<heckler>thanks people

16:20<king_john_eel>question - is it possible to stream to twitch from linode? That is, have an instance that runs something like x11, then run an openGL app, and then OBS, and then make it stream to twitch

16:32<nate>king_john_eel: Any sort of GPU rendering on a linode that isn't like GPU-dedicated isn't likely gonna go far
16:32<nate>You're also probably gonna eat through bandwidth pretty quickly
16:33<king_john_eel>yeah not expecting it to be cheap, but I guess at the minimum you need a GPU dedicated server?
16:34<nate>Yeah but the GPU dedicated plans here aren't really intended for game streaming or anything of the sort so much as hard-processing (which is why they start out hardware-heavy at $1k/month)
16:34<king_john_eel>oh yeah, looking at that plan now

20:07<Cromulent>what GPUs do Linode use in their GPU instances?
20:08<Peng>"Discover the performance of industry-leading NVIDIA Quadro RTX 6000 GPU cards."
20:08<Cromulent>thanks
20:25<nate>dwfreed: Closer to 8Mbit generally last I did any streaming at 30FPS w/ audio included, can double that if you're doing 60FPS
20:28<Peng>what does a 1080p .gif stream at
20:28<nate>depends what frames it's at too :P
20:33<Cromulent>hmm twitch streams max out at 6Mbit and people do 1080p on that just fine
20:38<nate>Cromulent: Not since they implemented 60FPS support as far as I'm aware
20:38<nate>Cromulent: And are you talking -downstream- or? Cause my last OBS run at 30FPS 1080 was doing like 7.7Mbit up, and that was only doing a 96Kbit audio layer like they recommend
20:39<Cromulent>nate: check out the bitrate range https://help.twitch.tv/s/article/broadcast-requirements?language=en_US
20:40<nate>Hm, maybe had a different mode setup going at the time. Guess I'll have to find time to do another stream and see

23:36<nyancat>what measurement does linode use for the traffic graphs
23:36<nyancat>it says 332.04mb/s but does that mean 332.04MB/s ?
23:36<nyancat>Or is this Mbps
23:37<nyancat>This should be a stupid question but I feel like it's not
23:38<millisa>the rrdtool graphs?
23:39<millisa>If you're talking about the ones on the linode details pages in the old/new manager; they say bits/sec on the left side
23:53<nyancat>yeah, the ones in the new cloud manager
23:56<@mcintosh>"mb" wouldn't be megabytes
23:56<@mcintosh>i think the graphs would be in bits, either way though
23:57<@mcintosh>so, mb would be millibits
23:58<@mcintosh>and i would consider 332.04mb/s negligible traffic in the vast majority of cases
