[00:01] <wendico> tomreyn: still here?
[00:04] <LastTalon> Alright.
[00:04] <LastTalon> So it worked this time.
[00:04] <LastTalon> Not sure what was going wrong.
[00:04] <LastTalon> Thanks for your help anyway, sarnold
[00:07] <sarnold> LastTalon: heh, bummer.. I hate not knowing what caused an issue :)
[00:18] <wendico> ok thannk you, with all the info you gave me, i writted down a working plan, may y post it for you to see if i got it correctly. Thank you for suggestions https://imgur.com/a/nnDfaY5
[00:19] <sarnold> wendico: iwconfig is still useful
[00:20] <wendico> sarnold: noted, thank you i actually want my server to be wireless access point, i think i need it for that
[00:20] <sarnold> wendico: aha, then also take a look at wpa_supplicant and ...
[00:20] <sarnold> wendico: .. hostapd
[00:21] <wendico> sarnold: ok noted, i think i even remember using those things in that old times of WEP aircrack
[00:21] <sarnold> :D
[00:22] <wendico> i asked on ubuntu channel but i would like a second opinion, for my virtual test, virtualbox right?
[00:23] <sarnold> I'd rather use qemu/kvm .. install virt-manager and use that instead
[00:23] <wendico> but that im gonna do on my desktop, in case u think im installing that on my server
[00:24] <wendico> just for the test server 1 on the screenshot i prefer use my desktop since is more powerfull, im running ubuntu desktop last version clean install
[00:24] <wendico> for that also qemu/kvm?
[00:25] <sarnold> wendico: yeah; libvirt is the best way to use qemu and kvm, and virt-manager is definitely the easiest way to use libvirt
[00:27] <wendico> thank you sarnold, noted down and reading on it, runned sudo apt-get revome virtualbox ;)
[00:29] <sarnold> libvirt can do some really cool things.. you can have the virt-manager front-end program on one computer manage the VMs run on a bunch of other computers
[00:29] <sarnold> I don't actually like libvirt much, but it's still the best / easiest ..
[00:30] <wendico> can i just sudo apt-get install libvirt or should i read on it, i have experiencce only on vmware
[00:31] <sarnold> I think apt-get install virt-manager  would bring in all you need
[00:32] <wendico> ty
[01:07] <keithzg> Starting to worry that there's something weirdly wrong with the ethernet adapter in this new server, since when it's plugged in it seems to be killing our router's internal-facing network adapter . . .
[01:10] <sarnold> keithzg: o_O
[01:16] <keithzg> It's really disconcerting, if I turn the new machine on and plug it into our network in our server room, at some short but seemingly random interval (up to a few minutes) the internal-facing ethernet adapter on our router dies like so: https://paste.kde.org/prxgycxci
[01:46] <keithzg> Hmm, seems like it might be a known-ish bug? Seems potentially fixable by either disabling some offloading on the network device, or by compiling and installing a newer version of the Intel e1000e driver.
[01:47] <keithzg> In the meantime though keeping the new server plugged in on the other side of the building seems to have solved things so I might just leave things like that and leave for the weekend :P
[01:56] <keithzg> ...clearly I spoke too soon.
[01:58] <sarnold> fwiw I've always had an impression turning off offloading was a good step to take
[01:58] <sarnold> is that a possibility for your load?
[02:02] <keithzg> sarnold: That's certainly what I'm about to try! Until now the machine in question has shown *tons* of headroom CPU-wise, so we'll see if disabling a ton of the offloading is too much for it or not (a bit more CPU usage is a small price to pay if it means the adapter isn't dying, heh)
[02:03] <sarnold> I have a small hunch that it wouldn't be a big deal for gigabit nic anyway, there just isn't that much data to move around on such a slow medium..
[02:03] <keithzg> Yeah and it's not like our uplink to the wider internet is gigabit anyways, so the actual traffic through our router should be even more modest still.
[02:16] <keithzg> Welllll that didn't work.
[02:17] <keithzg> Maybe disabling offloading for gro, gso, tso, tx, rx, and sg wasn't enough?
[02:19] <sarnold> what's left? :)
[02:19] <keithzg> ufo, lro, ntuple and rxhash I guess?
[02:20] <keithzg> (But yeah not much that seems likely)
[03:07] <keithzg_> Well nothing so far has worked. Current plan, upgrade the router to 18.04 and hope that magically fixes things somehow :P
[03:40] <keithzg> That . . . seems to have worked? At least kindof?
[03:40] <keithzg> Definitely seeing packet loss though.
[13:14] <wendico> how do i get out of full screen of my virt-manager machine? ty
[14:26] <tomreyn> wendico: in case you didnt find out, yet: you move the mouse to the top cente rof the screen, where two icons should then show up, one of which exits full screen
[14:27] <tomreyn> personally, i do like using virtualbox on desktop type computers, and prefer it over kvm/libvirt/virt-manager there.
[14:28] <compdoc> Ive been using kvm for years. I like much better
[14:29] <tomreyn> i definitely prefer kvm + libvirt for (headless) servers
[14:32] <tomreyn> kvm is more flexible in terms of virtualization and doesn't require proprietary add-ons for some functionality. but virtualbox integrates better in a desktop., the GUI is better.
[14:33] <tomreyn> (which is, of course, a subjective judgement, as with all GUIs)
[15:07]  * compdoc subjects tomreyn to some harsh judgement
[15:13] <wendico> tomreyn: compdoc: thanks both. i was blind, yes i finally found out just move mouse top. i preferred virtualbox but doesnt work on my fresh installed ubuntu desktop
[15:14] <wendico> i even followed a post to install virtualbox 5.2 on ubuntu 18 but still could not make it work, to not bother you i decided try virt-manager
[15:15] <wendico> worked like a charm on first try and got machines running, just coz im old im blind could not get out full screen, solved
[15:22] <compdoc> 10.04 is still a little fresh. Ive had some weirdness
[15:22] <compdoc> *18.04
[15:39] <wendico> i want to use my server as access point with a wireless im reading on wpa supplicant and hostpad. should i `sudo apt install wireless-tools` or should i go on reading to install more specific pacages? Ty
[15:54] <wendico> is this option on my server "sudo apt-get install --no-install-recommends ubuntu-desktop" to bad for a very small bussiess? or could be a reasoable solution for easy server managment?
[15:57] <tomreyn> on your desktop, this is fine, on your server, i would not do this.
[15:58] <tomreyn> if you require GUIs you'd be better served with the webmind/uermin/virtualmin... package
[16:04] <wendico> thank u tomreyn, im exactly on that path
[16:04] <wendico> what about wireless support, should i `sudo apt install wireless-tools` on my server?
[16:04] <wendico> thank you
[16:13] <tomreyn> yes, probably. i've never setup a wireless access point, so i'm not going to be much help there.
[16:15] <tomreyn> i assume you can do it using network-manager and nmcli or nmtui, though
[16:17] <wendico> tomreyn: thank you i try but i think is not gonna be posible, hostapd or iwconfig commands ask me to install wireless tools or hostapd
[16:17] <tomreyn> i think you'll need all of those
[16:18] <tomreyn> iwconfig, hostapd, wireless-tools are the low level commands, network-manager or (alternatively) systemd-networkd are higher level management utilities.
[16:19] <tomreyn> netplan would sit on top of the stack, but i can't seem to figure out how to configure a wirelless AP using netplan.
[16:20] <tomreyn> so i guess i'd scratch netplan there for now and se whether it can be done with either systemd-networkd (default for servers) or network-manager (default for desktops)
[16:21] <tomreyn> nmcli / nmtui are non graphical frontends to the network-manager instrumentation / framework for managing network interfaces.
[16:36] <wendico> thank you tomreyn. By the way, seems i cannot add a wireless virtual card on my virtual server
[16:39] <wendico> im gonna try to add the physical wireless card host hardware to the virtual machine to see if the virtual machine detects as wireless adapter for the testing
[16:45] <tomreyn> i'm not aware of any way to emulate wireless network devices
[18:03] <wendico> no, confirmed, not adding wifi posible on my virtual if anybody knows how tell me please, not even adding the hardware anfitrion wifi as bridged on the virtual machine shows as not wifi
