=== poster is now known as Poster [06:05] 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. [06:08] Mead: https://help.ubuntu.com/lts/serverguide/preparing-to-install.html [06:08] Mead: It all depends what services you intend to run on it [06:10] mainly just kvm and guest OS's [06:11] could it be installed on say an 8 or 16 gig flash drive? [06:17] Good morning. [06:18] good evening [06:20] o/ [12:51] 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. [12:52] my xorg log is as follows http://paste.ubuntu.com/24287725/ [12:55] zetheroo: server people don't know xorg. Try #ubuntu. [12:55] ok [12:56] 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? [13:01] zetheroo: looks like there's no video device [13:01] no dri, no framebuffer [13:02] aparantly I need a gdm\ [13:02] no video device? hmm .. ok [13:02] zetheroo: well the errror log you pasted shows no valid gpu, look at the (EE) entries [13:03] its a VM set to VMware compatible ... whatever that is :P [13:03] could be just appropriate driver missing [13:05] zetheroo: otoh, check if xserver-xorg-video-vmware is installed [13:06] installed lightdm and rebooted - I have login screen [13:06] though the resolution is huge - LOL === rchavik is now known as TheCroogoBot [13:08] 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 [13:09] zetheroo: you'll have to check the logs (perhaps via ssh) [13:10] I am in there but not sure which logs to be hunting down [13:10] 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] zetheroo: journalctl -n -p err is a good start [13:10] ok, I'll duck back in there then :D [13:11] whole bunch of this: [13:11] Mar 31 15:07:33 orbit1604 lightdm[1344]: PAM unable to dlopen(pam_kwallet5.so): /lib/security/pam_kwallet5.so: cannot [13:11] Mar 31 15:07:33 orbit1604 lightdm[1344]: PAM adding faulty module: pam_kwallet5.so [13:12] kwallet is kde... did you install kde? [13:13] no, I think thats installed by default ... even on Ubuntu Desktop [13:13] (I see you asked in #ubuntu too, so yeah, bettre there) [13:15] FUK === TheCroogoBot is now known as rchavik [13:16] 👍 === rchavik is now known as CroogoBot === CroogoBot is now known as rchavik === gimmic_ is now known as gimmic === nacc_ is now known as nacc [14:48] hey all, wondering if I can install php5.6 on Ubuntu 16 without adding the odrej/php PPA? [14:48] I'm working with a server that has no internet connectivity and will never have one. [14:49] It only has access to Ubuntu repos [14:52] meh 8G for / seperated form the rest is not enough anymore [14:52] *from [14:53] jge: no, you cannot [14:57] jge: you could create a 14.04 container inside the 16.04 machine and have php 5.5. [14:57] 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? [14:58] Though if it won't matter, then ondrej's PPA shouldn't either I suppose, so perhaps I don't understand your scenario. [15:01] rbasak: I just asked the firewall team, they agreed to allow access to that PPA (life's good again ;) [15:03] jge: not sure why you can't just use 14.04? === admcleod is now known as not_adam === not_adam is now known as admcleod [16:09] 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 ‘Login 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 it’s not booting from it? [16:10] dn`: does it drop you to a shell? [16:10] yes [16:11] dn`: are you able to login to the iscsi target from the shell? [16:11] (it’s the first time I do this, so it might be something very stupid I’m missing) [16:11] … it just booted... [16:11] I think I know now why [16:11] one sec.. [16:12] I think the ipxe(?) keept the connection open and I set the max con limit per target to 1 [16:12] dn`: ah [16:12] just to debug I set it to 2 .. but that can’t be slution can it? [16:13] dn`: not sure [16:14] this took me longer then it should have;-) [16:33] 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 — do you know if the files in iscsi/nodes/iqn… or iscsi/send_targets/:IP… get auto generated? [16:34] dn`: you mean you were going to install using one lun and then treat that as a 'master image'? [16:35] yes - I thought that idea would be good - bad idea? [16:35] the problem is I would also do it with preseed/kickstart - I wouldn’t mind but I can’t find a iscsi example;-) [16:36] dn`: so the problem you'll find, depending on your config is [16:36] a) all of them will share an initiator name [16:37] b) you may want to read README.Debian from open-iscsi [16:38] I assumed I could change the initiator name for each - I don’t need to install them in parallel [16:38] dn`: i would suggest modifying your root imagea [16:38] dn`: and make it not used on its own [16:38] dn`: if that makes sense [16:38] not sure I follow - ‘not used on it’s own?’ [16:39] dn`: some context on what i mean: https://naccblog.wordpress.com/2017/03/30/iscsi-initiator-names-in-cloud-images/ [16:39] dn`: treat it as a master image [16:39] dn`: well, you can use it, i guess [16:39] dn`: but i mean, it sounds like basically you're doing your own little cloud :) [16:39] dn`: and that requires making sure your 'image' is clean [16:39] smoser: --^ :) [16:39] ah, yes - that’s kinda the plan [16:39] dn`: things like ssh host keys, iscsi initiator names, etc. should be unique [16:40] hmhm, ssh host keys is a good point - guess I’ll try to figure out how todo it with preseed/kickstart [16:40] but this will create many tears from past tries ;-) [16:40] dn`: we (server team) are talking about this generally [16:41] dn`: but i don't think it's 'solved' yet :) [16:41] iscsi via preseed? [16:41] dn`: making a clean image to use [16:41] dn`: given an installed instance [16:41] ah - I think it’s not insane hard [16:41] there is a command to regnerate the host key or you could just delete it (auto generate on start then) [16:41] without having tohave a script go and do it :) [16:41] ah;-) [16:41] yeap, that would be nice - but if I can have one request [16:41] “fix” pressed ;-) [16:42] I often have to install machines without ipmi [16:42] what's wrong with preseed? or do you mean iscsi support in preseed? [16:42] and then preseed can be a super awesome tool [16:42] yes, iscsi support and something different then partman ;-) [16:43] 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] 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 can’t ‘not’ create it [16:43] dn`: tbh, there's an entirely new instller in development (subiquity) -- not sure on preseed support there [16:43] powersj: you asked about that on the list, right? [16:44] smoser: yep, i think that's true, as there is an initramfs hook in the package [16:44] nacc: can subiquity do a non interactive install?:) [16:44] how stable is it?:) *googleing* [16:44] dn`: no idea :) [16:44] dn`: not stable, afaict [16:44] dn`: it's still internal, mmaybe [16:45] found the repo [16:45] dn`: yeah, it is in active development [16:45] but I guess I’ll try to figure out if iscsi is or is not possible with preseed :/ [16:45] this at least refers to it: https://gist.github.com/Lupul/0accbdc94b8a5ce674d7 [16:46] nacc: yeah I did ask about it. I think still need to understand where it would be used and by whom [16:46] 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] and use cloud-init or some other "first time" thing. [16:47] dn`: --^ [16:47] basically then, get yourself a pristine image (from cloud-images.ubuntu.com, have to add a kernel if you need a hardware kernel) [16:48] 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. [16:49] smoser: that’s 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] nacc: thanks - will try to figure that out [16:49] nacc: maybe it’s easy as addres sis the IP and multiselect is the name/iqn [16:49] that would be WOHA ;-) [16:56] how woudl you evaluate the different performances of more slower cores vs fewer faster cores when it comes to concurrency? === drab_ is now known as drab [16:57] drab: what do you care about? define a performance metric and measure it [16:58] 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 [16:59] drab: ... so how would you evalutate this at all? thought experiment? [17:00] 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] I coulsd possibly try to recreate something with containers and limiting cores, but don't think I can influence freq at all [17:00] drab: right, you never said 'hosting scenario' -- so # of VMs is a performance metric === chmurifree is now known as chmuri [20:44] 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] its being antisocial [20:44] is openssh running? [20:48] arooni: connection refused suggests that some endpoint or intermediary recived your connectrion and decided to actively drop it. [20:49] 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] but also a firewall, wherther host or network based could do such. [20:49] most of the time, firewalls would just drop the traffic, though [20:49] (which would result in a timeout message, not the one you got) [22:41] 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. [22:51] Mead: start with specific software you want/need [22:56] you can also install a minimal desktop like mate. which then allows you to remote into it [22:58] my life would be a living hell with remote dektops [22:59] that kinda defeats the purpose :) [23:02] nothing but net. I get it === nchambers is now known as Guest21588 [23:15] Mead: you could even install a graphical environment. Which will not help much in configuring services on your server.
