| Rovanion | Hi, I'm getting the following errors on one of my drives in syslog and after a while it's lost to the system: http://paste.ubuntu.com/10855746/ | 11:53 |
| Rovanion | Does anyone know how to find the cause of this issue? | 11:54 |
| Rovanion | This is my complete dmesg for ata1: http://paste.ubuntu.com/10855773/ | 12:01 |
| lordievader | Rovanion: Drive failure? Check smart. | 12:23 |
| Rovanion | lordievader: Nothing notable on the smart record as far as I can see. Though they're hard to read. At least smartctl0 -H /dev/sdx returns passed on all devices. | 12:26 |
| Walex | Voyage__: setting up an SMTP server is not complicated if it is simple. For spam filters sometimes it helps to do SPF or some other idiotic authentication scheme. | 12:26 |
| lordievader | Rovanion: Could you pastebin the output of 'smartctl -a /dev/sdx'? | 12:29 |
| Rovanion | lordievader: Here it is: http://paste.ubuntu.com/10855877/ | 12:31 |
| lordievader | Drive seems to be fine, indeed. | 12:32 |
| Rovanion | I've read a bunch of different causes for erros like this. But I'm having a hard time discerning which could cause mine. Some are kernel, some are cable, some are controller and some are power issues. | 12:33 |
| Rovanion | So the disks works for something like half a day while inside a ZPool while resilvering(rebuilding) a mirror, then disappears from Linux totally. /dev/sdx isn't there anymore. | 12:35 |

| coetry | Can someone please help me with Amazon EC2? I have an instance that i changed the security group to accept all tcp connections from port ranges 0 - 65535, and i have rails serving on 0.0.0.0:3000 | 15:40 |
| coetry | but i can't seem to connect to the server from the public ip | 15:40 |
| coetry | its ubuntu server 14.04 | 15:41 |
| coetry | is there a firwall on the server or something thats stopping it from accepting connections? | 15:41 |
| coetry | http://pastie.org/10103500 | 15:44 |
| excalibr | coetry, iptables -nvL | 15:48 |
| coetry | excalibr: http://pastie.org/10103513 | 15:50 |
| excalibr | coetry, I see nothing is blocking on your server so it must be your network firewall then | 15:54 |
| excalibr | Have you tried giving your ec2 instance a reboot? | 15:56 |
| coetry | excalibr, i did reboot it :/ | 15:57 |
| === markthomas|away is now known as markthomas | ||
| excalibr | coetry, sorry I can't offer any further help. Ive never ran into such problem last time I used ec2. I did something differently though. I allowed all ports and proto in the security group and managed the firewall from within my instance | 16:07 |
| teward | coetry: check the EC2 control panel | 16:08 |
| teward | coetry: the security 'firewall' is controlled there, not at iptables | 16:08 |
| teward | you have to enter 'security group' allowed ports to permit access to the systems | 16:08 |
| teward | otherwise the default is block all but SSH | 16:08 |
| teward | (that Standard Operating Procedure hasn't changed in Amazon EC2 ever) | 16:09 |
| tyhicks | jamespage: hello - we've finally got through all the MIR security reviews that were ahead of the conntrack MIR (LP: #1381450) | 17:03 |
| tyhicks | jamespage: but we're not sure if it is still useful to do this week | 17:03 |
| tyhicks | jamespage: if sarnold could get through it in the next day or two, would it still be useful for 15.04? | 17:04 |

| jamespage | tyhicks, yes please | 17:19 |
| tyhicks | sarnold: ^ could you focus on that and cve triage today? | 17:20 |
| sarnold | tyhicks: sure | 17:20 |
| tyhicks | sarnold: thanks! :) | 17:21 |
| * sbeattie assumes tyhicks meant s/cve triage/community/ today | 17:23 | |
| tyhicks | sbeattie, sarnold: ah, I got your roles mixed up | 17:24 |
| tyhicks | that's even better for sarnold :) | 17:24 |
| * sbeattie *knew* not to get his hopes up. :) | 17:25 | |
| sarnold | yes, yes it is :) | 17:25 |
| sarnold | sorry sbeattie | 17:25 |
| sarnold | sbeattie: I've already started process_cve with the kjernel-team merge.. I'll finish just that bit.. | 17:26 |
| tyhicks | doh | 17:26 |
| sarnold | .. unless you've already started, then I'll try to figure out how to bail | 17:26 |
| tyhicks | I really screwed that up | 17:26 |
| sbeattie | sarnold: no, go ahead and finish that bit. | 17:27 |
| sarnold | CVE-2013-4866 (1/78: 1%) | 17:29 |
| sarnold | ouch.. | 17:29 |
| sarnold | sbeattie: okay, kernel team merge checked in, thanks | 17:29 |
| * sbeattie cries | 17:30 | |
| sarnold | ... if there's any bright side, the first issue from debian that it prompted for me was this: (The LIXIL Corporation My SATIS Genius Toilet application for Android ...) | 17:31 |
| sarnold | which is hilarious in itself | 17:32 |
| sarnold | but also hopefully means debian went crazy finding NFUs to document.. I hope. | 17:32 |
| Alina-malina | lol at dan bilzerian | 17:35 |
| Voyage | sarnold, ok. what precautions should be made while making an smpt server | 17:47 |
| sarnold | Voyage: keep up on your logs | 17:48 |
| Voyage | sarnold, need my emails to not go in spam folders | 17:48 |
| lazyPower | Voyage: thats a trust based system that takes time | 17:56 |
| lazyPower | the easiest thing you can do starting off is set DKIM validation on your dns for the server, then you have to wait and send mail while it builds trust | 17:57 |
| Voyage | k | 17:57 |
| lazyPower | http://en.wikipedia.org/wiki/DomainKeys_Identified_Mail <- outlines it pretty well | 17:58 |

| tychicus | has anyone run into issues with tagged vlan's on 14.04, specifically with regards to intervlan routing? | 19:34 |
| tychicus | I'm running into an issue that seems to only affect my ubuntu machines, thinking maybe I have something wrong on the ubuntu configuration side | 19:35 |
| patdk-lap | what is intervlan routing? | 19:36 |
| tychicus | sorry inter vlan routing | 19:37 |
| tychicus | routing packets between vlan's | 19:37 |
| patdk-lap | I don't understand the usage of inter | 19:37 |
| patdk-lap | that would be external vlan routing | 19:37 |
| patdk-lap | inside vlan is l2, bridge | 19:37 |
| patdk-lap | so you just have normal l3 routing issues | 19:37 |
| tychicus | interVLAN is just the cisco nomenclature | 19:38 |
| tychicus | 2 vlan's | 19:38 |
| tychicus | default vlan 1 | 19:38 |
| tychicus | then vlan 200 | 19:39 |
| tychicus | vlan 200 is able to pickup an IP from local dhcp, or static assignment | 19:39 |
| tychicus | can talk to other devices on the same subnet, but can't see to exit the subnet | 19:39 |
| ay_caramba | wait till you get to routing on a stick | 19:40 |
| ay_caramba | ;) | 19:40 |
| tychicus | Kernel IP routing table | 19:40 |
| tychicus | Destination Gateway Genmask Flags Metric Ref Use Iface | 19:40 |
| tychicus | 0.0.0.0 192.168.28.254 0.0.0.0 UG 0 0 0 eth2 | 19:40 |
| tychicus | 0.0.0.0 192.168.200.254 0.0.0.0 UG 100 0 0 eth2.200 | 19:40 |
| tychicus | 192.168.28.0 0.0.0.0 255.255.255.0 U 0 0 0 eth2 | 19:40 |
| tychicus | 192.168.200.0 0.0.0.0 255.255.255.0 U 0 0 0 eth2.200 | 19:40 |
| tychicus | is how the local routing table is configured | 19:40 |
| tychicus | everything is fine with the default vlan | 19:42 |
| tychicus | it can talk to other devices on vlan 200 | 19:42 |
| === keithzg__ is now known as keithzg | ||
| patdk-lap | all this talk, but no question for what is wrong? | 19:49 |
| tychicus | what is wrong is that as soon as I ifup eth2.200 | 19:49 |
| patdk-lap | ? | 19:50 |
| tychicus | the vlan attached to eth2 can not communicate with vlan 200 | 19:50 |
| patdk-lap | what does routing tables have to do with that? | 19:50 |
| === bilde2910 is now known as bilde2910|away | ||
| patdk-lap | that has to do with forwarding | 19:51 |
| tychicus | as in ip_forward | 19:51 |
| tychicus | ? | 19:51 |
| patdk-lap | and routefilters, and .... | 19:51 |
| tychicus | here is the tutorial I used https://wiki.ubuntu.com/vlan | 19:52 |
| tychicus | is there something that is more complete? | 19:52 |
| tychicus | the ubuntu systems are the only ones having this issue, so I am trying to track down where I went wrong in the configureation | 19:53 |
| patdk-lap | that tutorial is complete, to setup a vlan | 19:57 |
| patdk-lap | that tutorial has NOTHING to do with routing between vlans | 19:57 |
| patdk-lap | for that, consult any firewall config tutorial you want | 19:57 |
| tychicus | the function of routing between vlan's is set up on the router | 19:58 |
| patdk-lap | so this is just an end machine? | 19:58 |
| tychicus | it works for every machine in the network execpt ubuntu machines | 19:58 |
| tychicus | yes | 19:58 |
| patdk-lap | well, fix up your default route then | 19:58 |
| patdk-lap | or turn of rp_filter | 19:58 |
| patdk-lap | rp_filter is a GOOD THING to have on | 19:58 |
| patdk-lap | but it doesn't work for multible default routes | 19:58 |
| tychicus | would I need to be disabled for eth2 the physical interface, or only for eth2.200 (vlan interface)? | 20:01 |
| patdk-lap | disabled for anything with a default gateway on it | 20:03 |
| patdk-lap | in your case, all | 20:03 |
| tychicus | what is the preferred way to do this? sudo echo 0 > sudo /proc/sys/net/ipv4/conf/all/rp_filter | 20:10 |
| tychicus | does not seem to work | 20:10 |
| sarnold | echo 0 | sudo tee /proc/sys/net/ipv4/conf/all/rp_filter or use sudo -s to get a shell first, then just echo 0 > /proc/sys/net/ipv4/conf/all/rp_filter | 20:11 |
| tychicus | sysctl -w | 20:11 |
| tychicus | ok thanks | 20:12 |
| tychicus | patdk-lap: thank you that worked | 20:14 |
| tychicus | sarnold: thank you toot | 20:14 |
| tychicus | s/toot/too | 20:14 |
| patdk-lap | add it into a /etc/sysctl.d/xxxx file | 20:27 |
