| jayjo | is it possible to use PAM if I have users that don't have passwords. Can I establish passwords for the users without being root? | 12:16 |
| jayjo | ls -l /etc/shadow | 12:16 |
| jayjo | sorry! | 12:16 |
| rbasak | Odd_Bloke: so a few bugs AFAICS. http://cloud-images.ubuntu.com/releases/16.04/release/ still refers to "DEVELOPMENT". https://cloud-images.ubuntu.com/locator/ doesn't list any EC2 images for Xenial. | 12:21 |
| Odd_Bloke | rbasak: wisur: There are some non-technical blockers on EC2 images for xenial; we'll deliver images there as soon as we can. :) | 12:21 |
| Odd_Bloke | rbasak: Good spot on the DEVELOPMENT thing; I'll file a bug. :) | 12:22 |
| rbasak | stephank: ^ | 12:22 |

| linuxmint | Hello, wget is not working. Error: Cannot write to '1WlAUJo’ (Success). | 12:26 |
| linuxmint | How can I join ##ubuntu. NickServ says channel is invite only. | 12:30 |
| teward | linuxmint: channel is #ubuntu | 12:30 |
| teward | not ##ubuntu | 12:30 |
| teward | linuxmint: but if you're on Mint, you are in the wrong channels | 12:30 |
| linuxmint | teward: thanks, but /join #ubuntu says I am banned. | 12:30 |
| linuxmint | Is there a process to correct this? | 12:31 |
| linuxmint | (it's for my ubuntu machine. | 12:31 |
| linuxmint | ). | 12:31 |
| hateball | !ban | linuxmint | 12:31 |
| ubottu | linuxmint: If you have been banned it is probably because you have not gone along with what is acceptable !behaviour. If you're not sure what acceptable !behaviour is please see http://wiki.ubuntu.com/IRC/Guidelines - If you think the ban was a mistake, please join #ubuntu-ops | 12:31 |
| linuxmint | Basically, re wget error. | 12:31 |
| linuxmint | ubuntulog: k, thanks. | 12:32 |
| linuxmint | not sure what hateball's comment means, sorry? | 12:32 |
| hateball | I'm not sure what is unclear, " If you think the ban was a mistake, please join #ubuntu-ops " | 12:33 |
| linuxmint | hateball: thanks, done. | 12:33 |
| linuxmint | Pretty quiet channel though. | 12:34 |
| Odd_Bloke | linuxmint: I suspect that 'linuxmint' is a default username on Linux Mint; as #ubuntu is not intended to answer Mint questions, the default user has probably been banned. :) | 12:34 |
| linuxmint | Odd_Bloke: yes, I suspect that. | 12:34 |
| linuxmint | I suppose I could ask Mint channel re this wget error: Cannot write to | 12:35 |
| linuxmint | Eventhough it's on an Ubuntu machine. | 12:35 |
| rbasak | So one Mint user does something bad, gets banned, and all Mint users can't get on IRC channels by default? That sounds like a crazy default! | 12:36 |
| teward | rbasak: heh | 12:36 |
| linuxmint | rbasak: hmm | 12:36 |
| Odd_Bloke | rbasak: I don't know for sure, but it sounds like a thing that could have happened. :p | 12:36 |
| jayjo | Is there a way to give a user a password without giving priveleges with that password? | 12:36 |
| linuxmint | I'll see if I can fix it. I left a message on #ubuntu-ops. Pretty quiet, so might take some time. | 12:36 |
| Odd_Bloke | jayjo: What do you mean by "priveleges"? | 12:36 |
| rbasak | linuxmint: change your nick to something less generic maybe? :) | 12:38 |
| jayjo | not completely sure - I just need the user to have a password for PAM authentication, but I don't wan that password to provide them with any additional priveleges/resources | 12:38 |
| rbasak | jayjo: ah. You can use PAM to do that, yes. | 12:38 |
| rbasak | If the thing authenticating uses PAM, your ability to customise that is pretty much entirely the point of PAM. | 12:38 |
| rbasak | Find a replacement auth module you want to use instead of pam_unix. | 12:39 |
| jayjo | I just want to make sure if I add a password to an account there is no additional default behavior granted to the user | 12:39 |
| jayjo | like sudo priveleges etc. just being cautious | 12:39 |
| rbasak | Oh | 12:39 |
| jayjo | or it won't allow them to ssh without keys or something like this, will it? | 12:40 |
| rbasak | If you're worried about that sort of thing, then don't give the user a Unix account at all. | 12:40 |
| === ubuntu is now known as Guest93068 | ||

| DirtyCajun | im having issues with my ubuntu-vm-builder. its building it properly... but not adding it to my qemu:///system | 18:18 |
| seven-dev | Hello, I'm having a problem with ssh can someone help me please? | 18:42 |
| ikonia | why don't you just state your problem | 18:42 |
| seven-dev | hum ok :P | 18:42 |
| seven-dev | I was trying to setup an ssh server on ubuntu server and I was having some problems because I thought the service was called sshd.service | 18:43 |
| seven-dev | and I would enable it and get a weird error saying it failed because the symbolic link has too many erros | 18:44 |
| seven-dev | errors* | 18:44 |
| seven-dev | too many levels* sorry | 18:44 |
| ikonia | seven-dev: what version of ubuntu are you using | 18:45 |
| seven-dev | 16.04 | 18:45 |
| ikonia | seven-dev: so that comes with ssh installed by default | 18:45 |
| seven-dev | now I have the service enabled but I can't disable passwordauthentication | 18:45 |
| ikonia | look in /etc/ssh/sshd_config | 18:45 |
| seven-dev | does it? I'm pretty sure I didn't select it | 18:46 |
| seven-dev | i did look at that and changed it | 18:46 |
| ikonia | it's part of the default build I believe | 18:46 |
| ikonia | (I could be wrong) | 18:46 |
| seven-dev | then reloaded the service but it still allows me to connect with a password | 18:46 |
| seven-dev | maybe it is but I still had that problem :P | 18:46 |
| maswan | did you remember to remove the leading "#" in "#PasswordAuthentication no"? | 18:47 |
| seven-dev | yes | 18:47 |
| seven-dev | oh wait | 18:47 |
| seven-dev | oh yes i did sorry | 18:47 |
| seven-dev | (I thought i had put yes, but i did put no) | 18:48 |
| seven-dev | any idea about what the problem might be? | 18:48 |
| maswan | That change works for me, but I haven't gotten around to 16.04 on the server side yet | 18:49 |
| seven-dev | to restart the service I did: sudo service ssh restart | 18:49 |
| seven-dev | (I'm still trying to understand ubuntu, I come from arch) I also did: service ssh restart, systemctl restart ssh | 18:50 |
| seven-dev | and the same with sudo and sshd instead, nothing disabled the password | 18:50 |
| seven-dev | btw another question, do I use service or systemctl to manage services? What's the difference between them? | 18:51 |
| ikonia | systemctl for systemd | 18:51 |
| seven-dev | hmm but I have both | 18:52 |
| ikonia | you don't you have systemd | 18:52 |
| seven-dev | I think this version of ubuntu doesnt have upstart but service seems to (not) work the same as systemctl | 18:52 |
| ikonia | there are some legacy system V / upstart scripts that are wrapped in systemd as I recall | 18:53 |
| sdeziel | service is the generic wrapper that should work for system V/upstart/systemd | 18:53 |
| seven-dev | oh ok that makes sense ty | 18:53 |
| sdeziel | seven-dev: can you paste sshd -T? | 18:54 |
| sarnold | I think upstart is still installed because desktop stuff still uses upstart session management | 18:54 |
| seven-dev | sdeziel: ok, I just restarted it, 1 sec | 18:54 |
| sarnold | sdeziel: oh that's cool! thanks | 18:54 |
| seven-dev | is this the same?: "systemctl status ssh" and "systemctl status sshd" | 18:55 |
| seven-dev | sdeziel: It says "could not load host key" | 18:57 |
| sdeziel | seven-dev: on Ubuntu, the service is named "ssh" | 18:57 |
| sdeziel | seven-dev: you need to run it as root/sudo | 18:57 |
| seven-dev | yeah, I was just asking because they give me the same output | 18:57 |
| seven-dev | ah ok sorry | 18:57 |
| sdeziel | odd, here "systemctl status sshd" gives https://paste.ubuntu.com/16054989/ | 18:58 |
| sarnold | odd, I get same output for both ssh and sshd | 18:58 |
| sarnold | lets try updating and try again :) | 18:59 |
| sdeziel | I vaguely remember having both working | 18:59 |
| tarpman | ssh.service contains Alias=sshd.service | 19:00 |
| sdeziel | hmm both work on my servers but not on my laptop | 19:00 |
| seven-dev | sdeziel: https://paste.ubuntu.com/16055009/ | 19:00 |
| seven-dev | oh you think maybe this is happening because I have the server running in root and my user? | 19:02 |
| seven-dev | not sure if i do, just an idea | 19:02 |
| seven-dev | eh, didnt work, still allows me to login | 19:04 |
| seven-dev | with a password | 19:04 |
| sarnold | so, uh, this is going to show more ignorance than I usually like to show.. | 19:05 |
| seven-dev | tarpman: oh ok so they're the same | 19:05 |
| sdeziel | seven-dev: I have ChallengeResponseAuthentication set to no here | 19:05 |
| seven-dev | hm let me try | 19:06 |
| seven-dev | I did that o purpose | 19:06 |
| seven-dev | 1 sec | 19:06 |
| sarnold | when sshd_config has usepam yes -- does sshd then use the /etc/pam.d/sshd file for e.g. password authentication too? mine at least include's common-auth, which uses pam_unix .. | 19:06 |
| seven-dev | sdeziel: oh ok I think it worked | 19:07 |
| seven-dev | but why didn't it work before | 19:07 |
| sdeziel | sarnold answered that ^ | 19:08 |
| seven-dev | what is pam sorry? | 19:08 |
| sarnold | pluggable authentication modules | 19:08 |
| sarnold | they let you configure your services to require different kinds of authentication or authorization checks, handle sessions, update passwords, etc.. | 19:09 |
| seven-dev | oh okok | 19:09 |
| sdeziel | hmm, UsePAM: "Because PAM challenge-response authentication usually serves an equivalent role to password authentication, you should disable either PasswordAuthentication or ChallengeResponseAuthentication." | 19:09 |
| sarnold | the config files in /etc/pam.d/* are used by services to describe which modules to use, with which parameters, when users log in or change passwords | 19:09 |
| sdeziel | so it's "either or" which leaves me wondering why you needed to disable both | 19:10 |
| seven-dev | so if I wanted to setup two step auth I would need a PAM, right? | 19:10 |
| sdeziel | seven-dev: not required IIRC | 19:10 |
| sarnold | seven-dev: that's usually how it is done, ye, see the libpam-duo package for one example | 19:10 |
| seven-dev | uhm | 19:11 |
| sdeziel | seven-dev: what I do is simply use "AuthenticationMethods publickey,password" and "PasswordAuthentication yes" | 19:11 |
| sdeziel | this way, no additional lib/configuration is needed but both key and passwords are required | 19:11 |
| sdeziel | this also has the advantage that you can put it in some Match blocks | 19:11 |
| sarnold | oo | 19:11 |
| seven-dev | you can have a key with a password right? | 19:11 |
| seven-dev | with those settings | 19:11 |
| sdeziel | seven-dev: the password *on the* key is not considered a 2nd factor | 19:12 |
| seven-dev | ok found this: https://wiki.archlinux.org/index.php/Secure_Shell#Two-factor_authentication_and_public_keys | 19:13 |
| seven-dev | sdeziel: Yeah I know I was just checking | 19:13 |
| sdeziel | http://paste.ubuntu.com/16055152/ => TFA for sudoers | 19:13 |
| seven-dev | I meant a cellphone key | 19:13 |
| sdeziel | then libpam-duo is probably a good idea | 19:13 |
| seven-dev | ok ty | 19:14 |
| seven-dev | I'll try that later ty :) | 19:14 |
| sdeziel | you are welcome | 19:14 |

| sdeziel | DirtyCajun: as a workaround you can pass net.ifnames=0 to the kernel boot command | 19:41 |
| === nodoubleg-lunch is now known as nodoubleg | ||
| DirtyCajun | that will only give it an ens0 tho right? | 19:43 |
| DirtyCajun | it still wont change it to eth0 | 19:43 |
| sdeziel | DirtyCajun: this will prevent the rename from eth0 to ensX | 19:44 |
| DirtyCajun | oh!. ok. why does it do that btw? i understand the meaningful naming change but its a vm.... | 19:45 |
| sdeziel | those are supposedly stable/predictable names | 19:45 |
| DirtyCajun | i guess i mean why doesnt ubuntu-vm-builder correct/accomodate for that | 19:45 |
| showaz | Where can I find a map of all public references to the similarity (SitteMap Tree) http://cloud-images.ubuntu.com/locator/ec2/ and https://people.canonical.com/~ubuntu-security/cve/universe.html ? | 19:45 |
| sdeziel | but they are quite annoying since your NIC name then depends on the PCI ordering which tends to be changing quite easily with VMs | 19:46 |
| sdeziel | DirtyCajun: I think that official cloud image use the net.ifnames=0 workaround. Maybe ubuntu-vm-builder could do the same | 19:46 |
| rcj | sdeziel, cloud images do not use net.ifnames=0, cloud-init is enabled to use the new systemd "predictable network interface names" | 19:47 |
| sdeziel | rcj: oh, thanks didn't know that | 19:47 |
| DirtyCajun | i just want to find a way to utelize the predictable name instead of bootlegging it | 19:48 |
| rcj | sdeziel, we are avoiding turning back to net.ifnames=0. the cloud and server images use the systemd network names in xenial | 19:48 |
| sdeziel | rcj: I'm glad that cloud-init properly supports this now. It's unfortunately not the case for every packages (LP: #1541678) | 19:49 |

| rcj | sdeziel, it is unfortunate that the experience isn't 100%, it is a big change. And net.ifnames=0 can provide temporary relief, I just wouldn't want people to make that a default tuning. | 19:50 |
| sdeziel | rcj: understood | 19:51 |

| jamespage | zul, hallyn. rharper: hey - just had a chat with someone who's trying to use the numa features of openstack with libvirt/kvm | 21:47 |
| rharper | jamespage: howdy! | 21:48 |
| jamespage | our packages are building with libnuma-dev (which enabled one numa feature) but not numad, which I think is disabling use of numad to manage CPU placement dynamically | 21:48 |
| jamespage | rharper, hey! | 21:48 |
| rharper | numad is not included in ubuntu at this time IIRC | 21:48 |
| jamespage | erm | 21:48 |
| rharper | we've discussed whether we should have something like that | 21:48 |
| rharper | numad is a perl script that calls the page migration code periodically | 21:49 |
| jamespage | rharper, is in universe... | 21:49 |
| rharper | it's avail in Fedora | 21:49 |
| rharper | ah, cool | 21:49 |
| jamespage | rharper, well I guess this is a little late for 16.04... | 21:49 |
| jamespage | rharper, I asked him to raise a bug so we can track it... | 21:49 |
| hallyn | sounds ogod, yeah i see it in universe | 21:50 |
| * hallyn fetches | 21:50 | |
| rharper | is there an issue with it ? | 21:50 |
| * hallyn leaves it to sarnold to puke all over it :) | 21:51 | |
| hallyn | not a perl script | 21:51 |
| rharper | it's "graduated" | 21:51 |
| hallyn | well at least it graduated to plain c | 21:51 |
| rharper | c seems like overkill for this | 21:52 |
| hallyn | 2500 lines | 21:52 |
| hallyn | i think i agree | 21:52 |
| hallyn | maybe they did it so they could attach file caps or make it setuid | 21:53 |
| rharper | jamespage: I'd definitely be interested in the details; libvirt itself will do the initial placement and confinement w.r.t affininty and cpusets; numad is about periodically kicking the kernel to do page migration; | 21:55 |
| jamespage | rharper, ok lets see what he shows up with for things that don't work without numad | 21:55 |
| rharper | yeah, can't think of what would block numad from working | 21:55 |
| rharper | it;'s sorta process agnostic | 21:56 |
| hallyn | wonder how much overhead it introduces | 21:56 |
| rharper | which part | 21:56 |
| rharper | numad or page migration | 21:56 |
| hallyn | numad | 21:56 |
| hallyn | running with -i 15 | 21:56 |
| rharper | the real question (which always comes up) is why isn;'t the existing in-kernel page migration code good enough | 21:57 |
| hallyn | good q | 21:57 |
| rharper | in addition to strategies (process migration vs. page migration to process) | 21:57 |
| hallyn | really based on the name i'd have expected this to be like the balancing thread in lxd, | 21:57 |
| rharper | and the impact on things like THP | 21:57 |
| hallyn | which re-balances contianers based on their limits as cpus are hotplugged | 21:57 |
| hallyn | but i guess not | 21:57 |
| rharper | and the heuristics on knowing how long and where the processes will run | 21:57 |
| rharper | looking at the code; they have rudimentary "Detection" of kvm processes with notes that things like io-threads may confuse it | 21:58 |
| hallyn | yeah, i don't see this passing MIR muster | 21:58 |
| DirtyCajun | i havent found even the slightest anything on the webz about the naming of the qcow2 file thats created. | 21:58 |
| hallyn | // FIXME: someday figure out some better way to do this... | 21:58 |
| rharper | right | 21:58 |
| hallyn | all right, let's see waht kind of justification they come up with :) thx | 21:59 |
| rharper | numad also provides a pre-placement advice service that can be queried by various job | 22:00 |
| rharper | management systems to provide assistance with the initial binding of CPU and memory resources for | 22:00 |
| rharper | their processes. This pre-placement advice is available regardless of whether numad is running as | 22:00 |
| rharper | an executable or a service | 22:00 |
| rharper | that looks like what openstack might be interested in | 22:00 |
| jamespage | hallyn, rharper; tbh this may be a red-herring | 22:00 |
| rharper | jamespage: ^^ | 22:00 |
| rharper | if the "nova scheduler" is asking for some numa data via numad | 22:00 |
| jamespage | rharper, hmm - looking | 22:00 |
| rharper | but not clear to me how we build qemu would affect this | 22:00 |
| rharper | https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/pdf/Performance_Tuning_Guide/Red_Hat_Enterprise_Linux-7-Performance_Tuning_Guide-en-US.pdf | 22:01 |
| rharper | jamespage: quote from that document | 22:01 |
| sarnold | gah I thought I gave feedback already on terrible user-space "kick the kernel to migrate pages" crap | 22:01 |
| jamespage | rharper, so numad appears to be used when the 'auto' value is provide in the xml for numa placement | 22:01 |
| rharper | but that's never worked for us ? | 22:01 |
| jamespage | rharper, I can't find use of that in the nova codebase | 22:01 |
| rharper | or folk have been adding it on ? | 22:01 |
| sarnold | if the kernel isn't doing migration enough/correctely etc it'd be far better to file kernel bugs and get it _fixed_ | 22:01 |
| rharper | jamespage: then indirectly via libvirt calls ? | 22:02 |
| hallyn | sarnold: :) | 22:02 |
| jamespage | rharper, so i suspect this might be a ERRENDUSER but lets see | 22:02 |
| rharper | sarnold: indeed | 22:02 |
| hallyn | exactly what rharper was saying earlier | 22:02 |
| rharper | it's a tricky beast | 22:02 |
| jamespage | rharper, hallyn: suggest we wait for the bug and see | 22:04 |
| hallyn | yup | 22:04 |
| rharper | jamespage: cool | 22:05 |
| Edgan | Are we not getting AMIs still 16.04.1? | 22:51 |
| teward | Edgan: patience | 22:52 |
| teward | they'll be ready as soon as they will be ready | 22:52 |
| teward | no sooner (sorry, no timelines) | 22:52 |
| Edgan | teward: I am advanced enough to make my own. I guess I should then. | 22:53 |
