following http://wiki.ltsp.org/wiki/Installation/Ubuntu is I want to manually handle the dhcp settings on my existing dhcp server, not using anything on the ltsp host, do i just not run ltsp-config dnsmasq?
13:26
and also disable dnsmasq, of course
13:37
just once I want to click the "i'm not a robot" box and have it fail.

<alkisg>
||cw: in general, using proxydhcp is recommended; if you're sure you don't want proxydhcp, you just run ltsp-config dnsmasq --no-proxy-dhcp
14:00
For example, in the next ltsp version, we'll start using ipxe, and have some "if client=xx send this boot filename, else the other" parts
14:00
So using proxydhcp you'd avoid the need to replicate all that login in your main dhcp server
14:01
(different files for ipxe, non ipxe, uefi, non-uefi, raspberries etc)

15:14
<||cw>
at the moment I have multiple ltsp servers with incompatible configs, and also normal PXE boot for diag utils. I'd liek to simplify that, but baby steps...
15:18
my main concern is what chaos will happen by suddenly introducing a proxydhcp
16:51statler has left IRC (statler!~Georg@gwrz.lohn24.de, Remote host closed the connection)

<||cw>
!install
19:21
<ltsp>
install: http://wiki.ltsp.org/wiki/Installation/Ubuntu for Ubuntu, or http://wiki.ltsp.org/wiki/Installation for other distributions
19:22
<||cw>
ppa:ts.sch.gr seems dead/missing?
19:22
should there be ~ in there?
19:25
or, is this command not using my a apt-proxy....
19:32kjackal has left IRC (kjackal!~quassel@2a02:587:3119:ef00:256f:ee95:772f:555a, Ping timeout: 258 seconds)
19:35
<||cw>
grr, goal is to not give this system direct internet and nly allow apt via proxy
19:35kjackal has joined IRC (kjackal!~quassel@2a02:587:3119:ef00:256f:ee95:772f:555a)
19:35
<||cw>
via apt-cacher-ng, specifically
19:40
<mwalters>
are you talking about the build image command?
19:40
with chroot?
19:44
<||cw>
no, just adding the PPA
19:44
<mwalters>
ic
19:44
<||cw>
it 100% a proxy/internet issue, the add ppa and keyserv tools don't use the apt proxy config
19:44
<mwalters>
ah ok
19:47
<||cw>
lol ubuntu's keyserver is down too?
19:47
this work for you? https://keyserver.ubuntu.com/pks/lookup?op=get&options=mr&exact=on&search=0x4F3A3E9FC07F4E831D87AC2D3C72607B03AFA832
19:47
add-apt-repository says 'Error reading https://keyserver.ubuntu.com/pks/lookup?op=get&options=mr&exact=on&search=0x4F3A3E9FC07F4E831D87AC2D3C72607B03AFA832: Service Unavailable'
19:47
<mwalters>
sure looks broken
19:48
it's dead, jim
20:07vagrantc has joined IRC (vagrantc!~vagrant@unaffiliated/vagrantc)
20:13
<||cw>
vagrantc: do you have a test system you can try adding the PPA on? i think something is broken, not sure if it's just me and my draconian security tho
20:15
<vagrantc>
i haven't ever used the PPAs ... i either use my own builds or upload to debian
20:16
and i don't have much of a test system other than some libvirtd/virt-manager virtual machines
20:20
<||cw>
add-apt-repository says 'Error reading https://keyserver.ubuntu.com/pks/lookup?op=get&options=mr&exact=on&search=0x4F3A3E9FC07F4E831D87AC2D3C72607B03AFA832: Service Unavailable'
20:20
which that url does seem to be broken. seems odd for ubuntu's keyserv to be down tho
20:23
<alkisg>
||cw: http://blog.emilburzo.com/2015/10/work-around-for-when-keyserverubuntucom.html
20:25* ||cw head-desks

'Error reading https://keyserver.ubuntu.com/pks/lookup?op=get&options=mr&exact=on&search=0x4F3A3E9FC07F4E831D87AC2D3C72607B03AFA832: Service Unavailable'
20:26
so, yeah, that didn't work
20:27
<vagrantc>
just get the same key from some other keyserver network
20:30
<alkisg>
||cw: the link I gave you says to specify "-k pool.sks-keyservers.net"; it works for me here
20:30
keyserver.ubuntu doesn't; but the pool does
20:32
Hrm scratch that; it works with another ppa, but not with ts.sch.gr
20:42nehemiah has left IRC (nehemiah!~nehemiah@hs-user-138.wia.cz, Ping timeout: 245 seconds)
20:47
<||cw>
and the error still says https://keyserver.ubuntu.com
20:56
<alkisg>
apt-key adv --keyserver pool.sks-keyservers.net --recv-keys 03AFA832
20:57
Or just wait until they fix the server :D
20:58
<vagrantc>
don't use short ids
20:58
use the full fingerprint if at all possible
20:58
<||cw>
and how's that done.
20:58
<vagrantc>
there are already entire copies of the strong set with shortid collisions in the wild and on keyservers
20:59
<||cw>
in my search I also found that apt-key is in process of being deprecated
20:59
still works for now tho
20:59
but this key stuff is all complicated by the fact I want it to work through apt-cacher
21:00
and apt-key doesn't seem to
21:00
<alkisg>
4F3A 3E9F C07F 4E83 1D87 AC2D 3C72 607B 03AF A832
21:00
||cw: apt cacher for plain web access?
21:01
<||cw>
well, for apt-related things.
21:01
<alkisg>
Isn't that for deb caching? How are keys related to that?
21:01
I'm not sure that keys go through the cacher
21:01
Use http_proxy for plain web access for console programs
21:01
<||cw>
doenst need cached, just proxied
21:02
<alkisg>
http_proxy then, not apt
21:02
<||cw>
yeah, the proxy env vars work for add-apt-repository, but not apt-key
21:04
woo server's back
21:15
well, that was more learning than I wanted to do today

<mwalters>
I hope you learned your lesson
22:52
<quinox>
breaking stuff is the best way to learn
22:52
especially if it's a remotely located computer without a nice hardware control module :D
