| Phanes | hello | 00:39 |
|---|---|---|
| Phanes | where is the ubuntu maintainer and developer channel | 00:39 |
| teward | Phanes: the general development channel is #ubuntu-devel, but if you're trying to reach the maintainer of a specific package, filing a bug is more useful | 00:53 |
| teward | anything under the Server Team's purview, we can poke here | 00:53 |
| Phanes | teward, im building a new distro so was looking for a doc that outlined the considerations made when deciding the components of the system and how they'd be implemented | 01:00 |
| Phanes | or a channel to spray questions into | 01:01 |
| teward | Phanes: not sure what kind of support you'll get from Ubuntu with that, just saying. | 01:06 |
| Phanes | what | 01:07 |
| Phanes | why | 01:07 |
| teward | there's really no specific channel I can direct you to for that... | 01:07 |
| teward | because there's more than just the "maintainer" and "Developer" aspect | 01:07 |
| Phanes | if it is worth a damn, they'll have documented it | 01:07 |
| Phanes | surely | 01:10 |
| tomreyn | i would bet that not all stretegic documents are open for the general public. | 01:14 |
| tomreyn | *strAtegic | 01:14 |
| tomreyn | there are those blueprints on launchpad, however, but that's mostly drafts. | 01:15 |
| Phanes | surely they're not just hoping good will somehow makes engineering happen | 01:15 |
| Phanes | please tell me canonical is smarter than that | 01:16 |

| Genk1 | hello folks | 09:59 |
| Genk1 | I have a basic question. I want to synchronize two web repertories /var/www on server 1 and /var/www on server 2 | 09:59 |
| Genk1 | I have choosed to use unison for two-direction synchro feature | 10:00 |
| Genk1 | my problem is how to figure out the best strategy to deal with permissions in such situations ? | 10:00 |
| Genk1 | do I have to set www-data as an ssh account in both servers ? | 10:01 |
| Genk1 | Do I need to setup a new account who has r/w access to /var/www ? and use it for the synchronization ? | 10:01 |
| Genk1 | what kind of stuff do people choose in such situations ? | 10:02 |
| Genk1 | some documentation suggest to use sudo ? | 10:03 |
| Genk1 | is this a healthy way to deal with such problems ? | 10:04 |
| === Malediction_ is now known as Malediction | ||
| ziyourenxiang | better to use a new account and keep www-data read only (assuming your web server is running as www-data) | 10:25 |
| maxb | unison sounds like a bad idea because it inherently requires human interaction to resolve in which direction changes need to be propagated | 10:32 |
| Genk1 | ziyourenxiang, OK thanks for your advice | 11:35 |
| Genk1 | maxb, you're some how right but can you suggest a better option ? | 11:36 |
| Genk1 | maxb, I was thinking about distrubuted FS like Gluster and CEPH but it seems to me that it's a little bit complex to manage | 11:37 |
| ziyourenxiang | other possibilities: if all your content are public then just mirror one of your web server from the other web server using wget or similar | 12:14 |
| ziyourenxiang | or use rsync driven by one side | 12:14 |
| ziyourenxiang | or follow any number of tutorials you can find to use git to 'publish' | 12:15 |
| tomreyn | NFS would have been an option, but he left | 12:34 |

| MASM | someone here, i have a problem with mdadm resync, the speed y so slow, ' finish=95954.6min speed=168K/sec ' | 15:04 |
| Poster | In my experience, slow resync with mdadm is generally caused by moderate/high IO to the device in question | 15:16 |
| MASM | when i start sync all system, the speed decreased, but i cancel the resync of mdadm and speed of hard disk get normal right now | 15:43 |
| MASM | i change the dev.raid.speed_limit_min | 15:44 |
| MASM | and it didn't change anything | 15:45 |
| Poster | There is a finite amount of bandwidth available to each device that makes up your mdN ; if you are writing to either the md or any other partitions on the physical disk, all contribute to the total amount of bandwidth to the device | 15:47 |
| MASM | Poster: you mean that will be the connector of the raid that is damaged? | 15:55 |
| MASM | when i start the sync all speed decrease in both disk, but when i stop, i check speed in both but it is ok | 15:56 |
| lordievader | MASM: What Poster means is that the available bandwidth of the drives is shared over the sync action and any other action it performs. Hence the speed dwindles if a sync action is going on. | 15:58 |
| Vamp898 | Hi there. I used this guide to setup SSSD on Ubuntu 14.04 https://help.ubuntu.com/lts/serverguide/sssd-ad.html and everything works perfect. But when i use the exact same guide for Ubuntu 16.04, i can join the AD, i can use getent to get user ids and groups and so on, everything works almost fine. Everythig except logging in (no matter if i use su, | 15:58 |
| Vamp898 | ssh or an DM) does work. Login as an user does not work (i type the password an then get "System error". When i switch user with root it works, but i also get there "su: system error" | 15:58 |
| Vamp898 | I tried this on a completely new/fresh Ubuntu 16.04 installation | 15:59 |
| MASM | lordievader: the only solution is?, restart in security mode, and do it? | 15:59 |
| lordievader | MASM: What? There is no solution, this is a hardware limitation. Each drive has a maximum bandwidth... | 16:00 |
| MASM | lorddievader: but "speed=168K/sec" is so slow, i saw in internet that the speed is more than this :S | 16:01 |
| lordievader | MASM: Oh, it could very well be that mdadm limits the sync speed in order to keep the raid usable. | 16:02 |
| Poster | I don't think it's that low by default | 16:03 |
| Poster | if you really want it to speed up, consider booting into single user mode to allow the resync to be (more or less) the only thing accessing the disks | 16:03 |
| MASM | the problem is hosting :S and don't see directly | 16:05 |
| MASM | i have a server dedicate | 16:06 |
| MASM | it is possible? | 16:06 |
| Poster | I don't understand the question or solution you are proposing | 16:07 |
| MASM | sorry, English isn't my native lenguaje, to consider booting into single user mode, is posible if i have a server dedicate, if the server isn't here with me? | 16:09 |
| MASM | the ssh will work? | 16:10 |
| Poster | single user mode has no network connectivity, you would need console access | 16:10 |
| Poster | well, you could start it I think | 16:10 |
| Poster | but generally console access is what you would need | 16:10 |
| Poster | either via KVM switch or if your system is virtualized, via whatever virtualization manager | 16:10 |
| MASM | Poster: i understand. | 16:12 |

| soop | there | 17:51 |
| tomreyn | i guess my question already indicated that i am not familiar with it. | 17:54 |
| jge | nvm, looks like chronyc -h someip tracking does what I want | 17:56 |

| ws2k3 | my ubuntu machine has a gigabit nic and is connected to a gigabit switch but it still shows 100Mb/s what can this be? | 21:43 |
| mybalzitch | failed autonegotiation, bad cable would be my guesses | 21:45 |
| soop | are you sure your port is gigabit? | 21:56 |
| ws2k3 | soop yes | 22:01 |
| ws2k3 | soop i probarly need to find the source of the issue on the cisco switch | 22:01 |
| JanC | can be a driver issue too | 22:09 |
| patdk-lap | can be most anything | 22:12 |
| patdk-lap | every wire must work, and configs set to autodetect | 22:12 |
| patdk-lap | or you dont' get gigabit | 22:13 |
| JanC | I've seen a NIC fall back to 100 or 10 Mbit/s depending on the kernel (& thus driver) version used | 22:13 |
| JanC | or Gbit/s | 22:14 |
| compdoc | it does need all 8 wires in the connectors. if you made any of the cables, then you are likely the cause | 22:29 |
| ws2k3 | compdoc they are not self made connectors just patch cable from factory so unlikeley the issue is in the cable | 22:33 |
| patdk-lap | unlikely? I receive lots of bad patch cables | 22:59 |
| patdk-lap | like 100 bad black patch cables, I don't use black ones anymore | 22:59 |
| patdk-lap | funny only black, the grey, blue, green, red, where all fine | 23:00 |
