| Mead | is there a system requirements or minimum recomended specs for ubuntu-server? I'm trying to figure how large of partition I should create for my install drive. | 06:05 |
|---|---|---|
| hateball | Mead: https://help.ubuntu.com/lts/serverguide/preparing-to-install.html | 06:08 |
| hateball | Mead: It all depends what services you intend to run on it | 06:08 |
| Mead | mainly just kvm and guest OS's | 06:10 |
| Mead | could it be installed on say an 8 or 16 gig flash drive? | 06:11 |
| lordievader | Good morning. | 06:17 |
| Mead | good evening | 06:18 |

| zetheroo | Hi all - I installed Ubuntu Server 16.04 onto a freshly created VM (Proxmox) using the minimal Ubuntu ISO. I then installed gnome-session-flashback and xorg, but I cannot get the desktop env to start with 'sudo startx' and it doesn't start on bootup. | 12:51 |
| zetheroo | my xorg log is as follows http://paste.ubuntu.com/24287725/ | 12:52 |
| rbasak | zetheroo: server people don't know xorg. Try #ubuntu. | 12:55 |
| zetheroo | ok | 12:55 |
| rbasak | zetheroo: seems odd that you're using startx though. Usually people use lightdm or similar. Why not just use the desktop installer if that's wha tyou want? | 12:56 |
| blackflow | zetheroo: looks like there's no video device | 13:01 |
| blackflow | no dri, no framebuffer | 13:01 |
| zetheroo | aparantly I need a gdm\ | 13:02 |
| zetheroo | no video device? hmm .. ok | 13:02 |
| blackflow | zetheroo: well the errror log you pasted shows no valid gpu, look at the (EE) entries | 13:02 |
| zetheroo | its a VM set to VMware compatible ... whatever that is :P | 13:03 |
| blackflow | could be just appropriate driver missing | 13:03 |
| blackflow | zetheroo: otoh, check if xserver-xorg-video-vmware is installed | 13:05 |
| zetheroo | installed lightdm and rebooted - I have login screen | 13:06 |
| zetheroo | though the resolution is huge - LOL | 13:06 |
| === rchavik is now known as TheCroogoBot | ||
| zetheroo | ok, I changed the VM display settings back to default (VNC) and now have a more sensible resolution at login. BUt when trying to login I get 'Failed to start session' in red text above the password input area | 13:08 |
| blackflow | zetheroo: you'll have to check the logs (perhaps via ssh) | 13:09 |
| zetheroo | I am in there but not sure which logs to be hunting down | 13:10 |
| blackflow | zetheroo: but indeed like rbasak said, at this point the problems are likely related to non-servery parts, so better ask in #ubuntu | 13:10 |
| blackflow | zetheroo: journalctl -n -p err is a good start | 13:10 |
| zetheroo | ok, I'll duck back in there then :D | 13:10 |
| zetheroo | whole bunch of this: | 13:11 |
| zetheroo | Mar 31 15:07:33 orbit1604 lightdm[1344]: PAM unable to dlopen(pam_kwallet5.so): /lib/security/pam_kwallet5.so: cannot | 13:11 |
| zetheroo | Mar 31 15:07:33 orbit1604 lightdm[1344]: PAM adding faulty module: pam_kwallet5.so | 13:11 |
| blackflow | kwallet is kde... did you install kde? | 13:12 |
| zetheroo | no, I think thats installed by default ... even on Ubuntu Desktop | 13:13 |
| blackflow | (I see you asked in #ubuntu too, so yeah, bettre there) | 13:13 |

| jge | hey all, wondering if I can install php5.6 on Ubuntu 16 without adding the odrej/php PPA? | 14:48 |
| jge | I'm working with a server that has no internet connectivity and will never have one. | 14:48 |
| jge | It only has access to Ubuntu repos | 14:49 |
| rizonz | meh 8G for / seperated form the rest is not enough anymore | 14:52 |
| rizonz | *from | 14:52 |
| nacc | jge: no, you cannot | 14:53 |
| rbasak | jge: you could create a 14.04 container inside the 16.04 machine and have php 5.5. | 14:57 |
| rbasak | jge: or, if it'll never have internet connectivity, install Vivid from an old archive and never update it. It'll be full of security holes but perhaps that won't matter? | 14:57 |
| rbasak | Though if it won't matter, then ondrej's PPA shouldn't either I suppose, so perhaps I don't understand your scenario. | 14:58 |
| jge | rbasak: I just asked the firewall team, they agreed to allow access to that PPA (life's good again ;) | 15:01 |
| nacc | jge: not sure why you can't just use 14.04? | 15:03 |

| dn` | I try to boot an iscsi Ubuntu via ipxe; I was able to install Ubuntu on the ipxe target via; on reboot I always get a āLogin error (Login status 0) on conn 7; 18 - encountered non-retryable iSCSI login failure; I disable any kind of authentication and was able to install on the target - anyone got an idea why itās not booting from it? | 16:09 |
| nacc | dn`: does it drop you to a shell? | 16:10 |
| dn` | yes | 16:10 |
| nacc | dn`: are you able to login to the iscsi target from the shell? | 16:11 |
| dn` | (itās the first time I do this, so it might be something very stupid Iām missing) | 16:11 |
| dn` | ā¦ it just booted... | 16:11 |
| dn` | I think I know now why | 16:11 |
| dn` | one sec.. | 16:11 |
| dn` | I think the ipxe(?) keept the connection open and I set the max con limit per target to 1 | 16:12 |
| nacc | dn`: ah | 16:12 |
| dn` | just to debug I set it to 2 .. but that canāt be slution can it? | 16:12 |
| nacc | dn`: not sure | 16:13 |
| dn` | this took me longer then it should have;-) | 16:14 |
| dn` | nacc: maybe another question, my basic plan was to prepare one lun - then clone this lun for each machine I need to install; so for each machine I assume I need to adapt the config - so I greped for the IQN in /etc and found it a various places - the most prominent is e.g. iscsi.iscsi.initframfs that I need to adapt ā do you know if the files in iscsi/nodes/iqnā¦ or iscsi/send_targets/:IPā¦ get auto generated? | 16:33 |
| nacc | dn`: you mean you were going to install using one lun and then treat that as a 'master image'? | 16:34 |
| dn` | yes - I thought that idea would be good - bad idea? | 16:35 |
| dn` | the problem is I would also do it with preseed/kickstart - I wouldnāt mind but I canāt find a iscsi example;-) | 16:35 |
| nacc | dn`: so the problem you'll find, depending on your config is | 16:36 |
| nacc | a) all of them will share an initiator name | 16:36 |
| nacc | b) you may want to read README.Debian from open-iscsi | 16:37 |
| dn` | I assumed I could change the initiator name for each - I donāt need to install them in parallel | 16:38 |
| nacc | dn`: i would suggest modifying your root imagea | 16:38 |
| nacc | dn`: and make it not used on its own | 16:38 |
| nacc | dn`: if that makes sense | 16:38 |
| dn` | not sure I follow - ānot used on itās own?ā | 16:38 |
| nacc | dn`: some context on what i mean: https://naccblog.wordpress.com/2017/03/30/iscsi-initiator-names-in-cloud-images/ | 16:39 |
| nacc | dn`: treat it as a master image | 16:39 |
| nacc | dn`: well, you can use it, i guess | 16:39 |
| nacc | dn`: but i mean, it sounds like basically you're doing your own little cloud :) | 16:39 |
| nacc | dn`: and that requires making sure your 'image' is clean | 16:39 |
| nacc | smoser: --^ :) | 16:39 |
| dn` | ah, yes - thatās kinda the plan | 16:39 |
| nacc | dn`: things like ssh host keys, iscsi initiator names, etc. should be unique | 16:39 |
| dn` | hmhm, ssh host keys is a good point - guess Iāll try to figure out how todo it with preseed/kickstart | 16:40 |
| dn` | but this will create many tears from past tries ;-) | 16:40 |
| nacc | dn`: we (server team) are talking about this generally | 16:40 |
| nacc | dn`: but i don't think it's 'solved' yet :) | 16:41 |
| dn` | iscsi via preseed? | 16:41 |
| nacc | dn`: making a clean image to use | 16:41 |
| nacc | dn`: given an installed instance | 16:41 |
| dn` | ah - I think itās not insane hard | 16:41 |
| dn` | there is a command to regnerate the host key or you could just delete it (auto generate on start then) | 16:41 |
| nacc | without having tohave a script go and do it :) | 16:41 |
| dn` | ah;-) | 16:41 |
| dn` | yeap, that would be nice - but if I can have one request | 16:41 |
| dn` | āfixā pressed ;-) | 16:41 |
| dn` | I often have to install machines without ipmi | 16:42 |
| nacc | what's wrong with preseed? or do you mean iscsi support in preseed? | 16:42 |
| dn` | and then preseed can be a super awesome tool | 16:42 |
| dn` | yes, iscsi support and something different then partman ;-) | 16:42 |
| smoser | nacc, just saying this out loud, i think that the "updated" iscsi.initiatorname probalby gets put into the initramfs at some point, and at that point the initramfs has a copy and is also then dirty. | 16:43 |
| dn` | e.g. assuming you have a 100GB disk, and you want something like 30GB used for / [ignore th enumbers etc] - you are forced to also create 70g parition - otherwise partman fails; you canāt ānotā create it | 16:43 |
| nacc | dn`: tbh, there's an entirely new instller in development (subiquity) -- not sure on preseed support there | 16:43 |
| nacc | powersj: you asked about that on the list, right? | 16:43 |
| nacc | smoser: yep, i think that's true, as there is an initramfs hook in the package | 16:44 |
| dn` | nacc: can subiquity do a non interactive install?:) | 16:44 |
| dn` | how stable is it?:) *googleing* | 16:44 |
| nacc | dn`: no idea :) | 16:44 |
| nacc | dn`: not stable, afaict | 16:44 |
| nacc | dn`: it's still internal, mmaybe | 16:44 |
| dn` | found the repo | 16:45 |
| nacc | dn`: yeah, it is in active development | 16:45 |
| dn` | but I guess Iāll try to figure out if iscsi is or is not possible with preseed :/ | 16:45 |
| nacc | this at least refers to it: https://gist.github.com/Lupul/0accbdc94b8a5ce674d7 | 16:45 |
| powersj | nacc: yeah I did ask about it. I think still need to understand where it would be used and by whom | 16:46 |
| smoser | if you're doing iscsi root... then it really seems best to me to shoot for doing image based clone rather than install. | 16:46 |
| smoser | and use cloud-init or some other "first time" thing. | 16:46 |
| nacc | dn`: --^ | 16:47 |
| smoser | basically then, get yourself a pristine image (from cloud-images.ubuntu.com, have to add a kernel if you need a hardware kernel) | 16:47 |
| smoser | and then just clone that thing. probably can even get away with putting a static /var/lib/cloud/seed/ in it for your metadata and user-data. or you can clone and then write those few files. | 16:48 |
| dn` | smoser: thatās what I tried, will look more into it - the problem is I need to clone the image at least twice I think for each installation ;-) | 16:49 |
| dn` | nacc: thanks - will try to figure that out | 16:49 |
| dn` | nacc: maybe itās easy as addres sis the IP and multiselect is the name/iqn | 16:49 |
| dn` | that would be WOHA ;-) | 16:49 |
| drab_ | how woudl you evaluate the different performances of more slower cores vs fewer faster cores when it comes to concurrency? | 16:56 |
| === drab_ is now known as drab | ||
| nacc | drab: what do you care about? define a performance metric and measure it | 16:57 |
| drab | nacc: yeah, the thing is, I don't have the hw test to on. So I'm not sure if 8 cores at 2.5GHz are going to do better than 4 cores at 3.2Ghz | 16:58 |
| nacc | drab: ... so how would you evalutate this at all? thought experiment? | 16:59 |
| drab | nacc: I was hoping someone here would have gone through similar considerations and maybe had the gear to test it, and knew that for eaxmple in a hosting scenario as a rule of thumb you're better off with faster CPUs and fewer core count or whatever configuration | 17:00 |
| drab | I coulsd possibly try to recreate something with containers and limiting cores, but don't think I can influence freq at all | 17:00 |
| nacc | drab: right, you never said 'hosting scenario' -- so # of VMs is a performance metric | 17:00 |

| arooni | what should i check when i get a 'Connection refused' message from my ubuntu 14.04 server when i try to ssh to it? | 20:44 |
| arooni | its being antisocial | 20:44 |
| dlloyd | is openssh running? | 20:44 |
| tomreyn | arooni: connection refused suggests that some endpoint or intermediary recived your connectrion and decided to actively drop it. | 20:48 |
| tomreyn | that's what an openssh server does when it's just starting up, or when you are connecting from an ip address not authorized to connect to it. | 20:49 |
| tomreyn | but also a firewall, wherther host or network based could do such. | 20:49 |
| tomreyn | most of the time, firewalls would just drop the traffic, though | 20:49 |
| tomreyn | (which would result in a timeout message, not the one you got) | 20:49 |
| Mead | welp I took the plunge, I've got ubuntu server installed, nothing but command line, now I have no choice but to learn how to configure everything in the CLI... so... now I guess I need a load of guides and documentation. Anyone kwow were to start? The more searchable the better. | 22:41 |
| blackflow | Mead: start with specific software you want/need | 22:51 |
| compdoc | you can also install a minimal desktop like mate. which then allows you to remote into it | 22:56 |
| compdoc | my life would be a living hell with remote dektops | 22:58 |
| blackflow | that kinda defeats the purpose :) | 22:59 |
| compdoc | nothing but net. I get it | 23:02 |
