[00:39] hello [00:39] where is the ubuntu maintainer and developer channel [00:53] 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] anything under the Server Team's purview, we can poke here [01:00] 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 [01:01] or a channel to spray questions into [01:06] Phanes: not sure what kind of support you'll get from Ubuntu with that, just saying. [01:07] what [01:07] why [01:07] there's really no specific channel I can direct you to for that... [01:07] because there's more than just the "maintainer" and "Developer" aspect [01:07] if it is worth a damn, they'll have documented it [01:10] surely [01:14] i would bet that not all stretegic documents are open for the general public. [01:14] *strAtegic [01:15] there are those blueprints on launchpad, however, but that's mostly drafts. [01:15] surely they're not just hoping good will somehow makes engineering happen [01:16] please tell me canonical is smarter than that === xar-- is now known as xar- === giraffe is now known as Guest57693 [08:46] what is "killall -0" doing? [09:59] hello folks [09:59] I have a basic question. I want to synchronize two web repertories /var/www on server 1 and /var/www on server 2 [10:00] I have choosed to use unison for two-direction synchro feature [10:00] my problem is how to figure out the best strategy to deal with permissions in such situations ? [10:01] do I have to set www-data as an ssh account in both servers ? [10:01] Do I need to setup a new account who has r/w access to /var/www ? and use it for the synchronization ? [10:02] what kind of stuff do people choose in such situations ? [10:03] some documentation suggest to use sudo ? [10:04] is this a healthy way to deal with such problems ? === Malediction_ is now known as Malediction [10:25] better to use a new account and keep www-data read only (assuming your web server is running as www-data) [10:32] unison sounds like a bad idea because it inherently requires human interaction to resolve in which direction changes need to be propagated [11:35] ziyourenxiang, OK thanks for your advice [11:36] maxb, you're some how right but can you suggest a better option ? [11:37] 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 [12:14] 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] or use rsync driven by one side [12:15] or follow any number of tutorials you can find to use git to 'publish' [12:34] NFS would have been an option, but he left === JanC_ is now known as JanC [15:04] someone here, i have a problem with mdadm resync, the speed y so slow, ' finish=95954.6min speed=168K/sec ' [15:16] In my experience, slow resync with mdadm is generally caused by moderate/high IO to the device in question [15:43] 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 [15:44] i change the dev.raid.speed_limit_min [15:45] and it didn't change anything [15:47] 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 [15:55] Poster: you mean that will be the connector of the raid that is damaged? [15:56] when i start the sync all speed decrease in both disk, but when i stop, i check speed in both but it is ok [15:58] 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] 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] 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" [15:59] I tried this on a completely new/fresh Ubuntu 16.04 installation [15:59] lordievader: the only solution is?, restart in security mode, and do it? [16:00] MASM: What? There is no solution, this is a hardware limitation. Each drive has a maximum bandwidth... [16:01] lorddievader: but "speed=168K/sec" is so slow, i saw in internet that the speed is more than this :S [16:02] MASM: Oh, it could very well be that mdadm limits the sync speed in order to keep the raid usable. [16:03] I don't think it's that low by default [16:03] 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 [16:05] the problem is hosting :S and don't see directly [16:06] i have a server dedicate [16:06] it is possible? [16:07] I don't understand the question or solution you are proposing [16:09] 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? [16:10] the ssh will work? [16:10] single user mode has no network connectivity, you would need console access [16:10] well, you could start it I think [16:10] but generally console access is what you would need [16:10] either via KVM switch or if your system is virtualized, via whatever virtualization manager [16:12] Poster: i understand. === nchambers is now known as ready === ready is now known as voldemort [17:07] anyone used chrony before? I'm trying to figure out how I would query another client for stats [17:08] looking for an equivelant of ntpq -p [17:25] anyone familiar with the official ubuntu mail-filter howto (spamassassin/amavis/postfix)? [17:45] where is that? [17:51] https://help.ubuntu.com/lts/serverguide/mail-filtering.html [17:51] there [17:54] i guess my question already indicated that i am not familiar with it. [17:56] nvm, looks like chronyc -h someip tracking does what I want === Monthrect is now known as Piper-Off [21:43] my ubuntu machine has a gigabit nic and is connected to a gigabit switch but it still shows 100Mb/s what can this be? [21:45] failed autonegotiation, bad cable would be my guesses [21:56] are you sure your port is gigabit? [22:01] soop yes [22:01] soop i probarly need to find the source of the issue on the cisco switch [22:09] can be a driver issue too [22:12] can be most anything [22:12] every wire must work, and configs set to autodetect [22:13] or you dont' get gigabit [22:13] I've seen a NIC fall back to 100 or 10 Mbit/s depending on the kernel (& thus driver) version used [22:14] or Gbit/s [22:29] it does need all 8 wires in the connectors. if you made any of the cables, then you are likely the cause [22:33] compdoc they are not self made connectors just patch cable from factory so unlikeley the issue is in the cable [22:59] unlikely? I receive lots of bad patch cables [22:59] like 100 bad black patch cables, I don't use black ones anymore [23:00] funny only black, the grey, blue, green, red, where all fine
