apsCarlFK: do you have experience using clusterssh?00:37
CarlFKnope00:37
apsok, then you need to start each encoder individually00:37
CarlFKbut there are 3 boxes that I might have to touch, so I am not too worried about it right now00:38
apsssh room3278.encoder.timvideos.us00:38
apstry00:38
CarlFKPermission denied (publickey).00:38
CarlFKwhat user?00:39
apsubuntu00:39
CarlFKthat's better - I am in00:39
CarlFKbut what if the box isn't up?00:39
apsYou need aws credentials from Tim00:40
apsokay, when you start ec2 machine for the first time, you need to do three things.00:40
aps1. sudo service flumotion start00:40
CarlFKshouldn't this be on a wiki page?00:40
apseverything is there00:41
apshttps://github.com/timvideos/streaming-system/wiki/Operating#get-the-encoder-running00:41
tpbTitle: Operating · timvideos/streaming-system Wiki · GitHub (at github.com)00:41
apsah, so basically u just need aws credentials00:41
CarlFKgot it.00:45
*** CarlFK has quit IRC00:53
mithroaps: you can ssh to Carl's box with "ssh [email protected] -p 2222"02:16
apsmithro: no, connection refused02:20
apstunnel is down?02:20
mithroaps: possibly02:20
apsYou're a bit free? I need to know how to fix preview server. nginx was not serving again02:22
mithroaps: "sudo service nginx start" ?02:24
apsdid that, still it wasn't working02:24
mithroaps: oh02:24
mithroaps: we ran out of IP addresses - so preview doesn't have a static IP address02:25
aps54.186.17.23802:25
mithrodns needs to be updated after every restart02:25
apsI could ssh but I didn't know how to fix02:25
apsI think it's that symlink thing you did.02:25
mithro$ ping preview.timvideos.us02:25
mithroPING preview.timvideos.us (54.200.134.15) 56(84) bytes of data.02:25
apsI tried a few things, but no luck02:25
mithroaps: problem isn't the machine02:26
apsoh, now I understand02:26
mithroyou need to update Route53 for both timvideos.us and timevideos.io02:26
apsyeah, this was pointing to some other person's ec2 :/02:28
apsor IP02:28
mithroaps: looks to be working now02:36
mithroaps: I sent Carl login information for my AWS account02:39
apsmithro: Good. Should preview server also be turned off when not in use?02:43
mithroIt's debatable02:43
apsand can we not run it an a free tier machine? I don't know how much power it needs02:43
mithroFree tier is to small02:44
mithroCan change the tier without reboot02:44
apsmithro: really? that could work but I think it's not possible without rebooting02:50
mithroThat should be can't02:51
apsah02:51
mithroStupid mobile02:51
*** Niharika has joined #timvideos02:51
apsand we should make Carl use config pusher and watchdog.02:52
apswatchdog works for collectors also, right?02:52
mithroaps: yes03:20

CarlFKmithro: I am logged in, but can't find the encoders07:04
mithroCarlFK: which region are you looking at?07:05
CarlFKhttps://console.aws.amazon.com/ec2/v2/home?region=us-east-107:05
CarlFKah, found it07:05
CarlFKI see the rooms, I see stopped.07:05
CarlFKI can go to sleep now07:05
mithroCarlFK: just starting up the encoders isn't enough07:11
CarlFKhttps://github.com/timvideos/streaming-system/wiki/Operating#get-the-encoder-running  that stuff right ?07:11

mithrowatchdog Ctrl-B, c for a new window07:12
mithroI believe it's actually Ctrl-A07:12
CarlFKoh yeah, I noticed it is using the screen meta key07:13
mithroCarlFK: depends if I installed my rcfiles or not07:13
mithroCarlFK: by default it's Ctrl-B07:13
mithroCarlFK: if my rcfiles are installed then tmux will automatically start up just by logging in07:14
mithroso don't do "tmux attach" if you see the tmux bar accross the bottom07:14
CarlFKk, I think I can figure out the tmux stuff07:17
*** techman83 has quit IRC07:17
mithrodoing tmux attach inside tmux will make you *very* confused07:17
*** techman83 has joined #timvideos07:18

apstmux will automatically start up on encoder machines07:39

mithroCarlFK: Rackspace came to the party!13:51
CarlFKmithro: what about Rack?13:56
mithroCarlFK: they will provide the TimVideos project with free infrastructure13:56
CarlFKvery cool13:57
CarlFKguessing 2k/month credit? (that seems to be standard)13:58
CarlFKI looked and skay confirmed with #rasckspace: you can't stop a box to stop billing.  you can halt it but you will still be billed.  you have to destroy it and rebuild it14:00
mithroCarlFK: interesting14:30
*** mparuszewski_ has quit IRC14:42
*** CarlFK has quit IRC14:47
apsmithro: if you're still up, is there a way to restore tmux session after restarting encoder machines?15:18
*** CarlFK has joined #timvideos15:48
*** ChanServ sets mode: +v CarlFK15:48
CarlFKI am going to try bringing up the 3 streams.. first time I think15:51
