<jinnjus>
Hey alkisg...I think I finished with irclogs for now unless there is anything that needs fixing
05:40
it now scrapes the navigation sidebar from the main site and I used css to squash it into the footer
05:40
<alkisg>
jinnjus: ty, let me upload it and see
05:41
<jinnjus>
now manual updates necessary from you if you change navigation links
05:41
not sure how brittle that will be for a solution...but I think it will work for now :)
05:43
*no manual update...
05:47
<alkisg>
jinnjus: hmm I think I did something wrong, check irclogs.ltsp.org now...
05:48
<jinnjus>
oops...I missed a css file in the header...sorry
05:48
one moment
05:48
<alkisg>
I changed home, pull before you push
05:49
Also I don't think the level-2 links are needed, just the top-level ones
05:49
well unless you're screen-scraping them, sure, ok
05:51
<jinnjus>
the css should clean it up
05:52
<alkisg>
Ah, at the bottom, nice!
05:52
Thank you jinnjus, great work!
05:53
<jinnjus>
is that better?
05:53
<alkisg>
Yes indeed I think it is
05:53
<jinnjus>
it's still messier than I'd like under the hood...there is lots of css I think uneccessary
05:54
but I don't know foundation at all
05:54
<alkisg>
Re: the analytics id, I'm thinking maybe we should add that in the future, no?
05:54
I just didn't have time for that yet
05:55
<jinnjus>
I don't know what it's for? I should google I suppose :)
05:55
<alkisg>
AFAIK it counts page hits and browser and user statistics
05:55
So we can see how many visit ltsp.org, how many the man pages, if they're using firefox or chromium etc
05:55
Not sure how much it helps for a project like ltsp though
05:56
Download statistics would make more sense than analytics
05:56
(we have those, for the ppa packages)
05:57
<jinnjus>
I added the head html stuff from the main site because it has meta info for search engines...I will look at the analytics stuff too though if you want
05:57
<alkisg>
I think it needs registration and mail etc, so I think I should be the one to do it, don't bother
05:57
<jinnjus>
OK...sounds good
05:58
<alkisg>
Is there a standard date selection control in html5?
05:58
To replace that dropping combo box?
05:58
<jinnjus>
oh yeah...good question
05:58
fixing up the style on that too was something I was thinking to do
05:58
<alkisg>
I think it's too long now, it takes a long time to load on mobile phones etc
05:59
Ah although we only want to show the dates where we do have data
05:59
Hmm
06:00
And I'm not sure if it would be indexable by google if it was using a control or javascript etc
06:01
....maybe it's fine as it is now
06:03
<jinnjus>
OK

<eddyTV>
Are there any examples of passing network parameters on the kernel command line in LTSP19 like the old "IPAPPEND" option could to avoid having to do DHCP again?

16:19
<alkisg>
eddyTV: file a community issue and I'll answer it when I get a bit of free time, with a nice POST_IPXE_SED command
16:27
<eddyTV>
By "community issue", do you mean at https://github.com/ltsp/ltsp/issues ?
16:27
<alkisg>
https://github.com/ltsp/community/issues
16:27
ltsp/ltsp is for bugs, ltsp/community for discussions
16:27
<eddyTV>
Gotcha. Glad I asked. ;-)

<eddyTV>
#63 opened. Thanks in advance, Alkis.
16:58
<alkisg>
eddyTV: try manually: set cmdline_ltsp ip=${ip}:${srv}:${gateway}:${netmask} BOOTIF=01-${mac:hexhyp}
16:58
In line 15 of ltsp.ipxe
16:58
If it works, I'll make it a POST_IPXE_SED command
17:05
<eddyTV>
OK... giving it a try now
17:06
close... no DNS server
17:06
<alkisg>
That's expected
17:06
IPAPPAND 3 doesn't pass the DNS
17:06
So you're supposed to pass it via ltsp.conf then
17:07
ltsp5 did another dhcp request to autodetect dns :)
17:07
<eddyTV>
Hmm, is it not in the PXE pre-boot environment? Or is passing it through just something that's not supported?
17:07
<alkisg>
Oh you can pass it via the cmdline if you want
17:07
But it's not supported by initramfs-tools, you need to do it via ltsp,
17:07
i.e.: ltsp.dns_servers=${dns-server}
17:11
<eddyTV>
any way to hide the `IP-Config` output when `quiet` is on the cmdline?
17:12
<alkisg>
Which distro/version?
17:12
Also, see reply in the issue
17:12
<eddyTV>
Ubuntu 18.04
17:12
<alkisg>
Your main problem seems to be a bad dhcp server
17:12
What dhcp server are you using?
17:12
<eddyTV>
Which is weird because it's dnsmasq on the local subnet
17:13
<alkisg>
In 192.168.67.x?
17:13
<eddyTV>
No, it's running on the gateway in the .1 of the primary subnet
17:14
<alkisg>
If it takes 4 seconds to answer, it sounds misconfigured
17:14
To hide boot messages in Ubuntu, add `quiet splash` in the cmdline
17:14
<eddyTV>
Yeah I have that, and the `IP-Config` stuff "leaks" through even though the rest of the kernel boot messages are hidden
17:14
<alkisg>
You have splash?
17:15
<eddyTV>
I have it set, but `Plymouth` isn't doing anything yet (that's the next thing I was going to look at)
17:15
<alkisg>
To test how long your dhcp server takes to answer, on a booted pc (server, client, whatever), run something like this:
17:15
/usr/lib/klibc/bin/ipconfig -n enp2s0
17:15
It should reply in less than 1 sec
17:16
bbl
17:16
<eddyTV>
`real 0m0.053s`
17:17
<alkisg>
Same from the booted client?
17:17
Maybe switches interfering or something
17:18
Or maybe it waits for ping replies, and it replies soon when the IP is already assigned to that client
17:18
<eddyTV>
Yes, that was from the booted client.
17:18
I can look at the switch. If link drops between iPXE and the kernel, maybe it's not going back to forwarding mode right away
17:20
<alkisg>
Btw both ltsp5 and ltsp19 don't interfere with ipconfig; there were no changes involved
17:26
<eddyTV>
Definitely a problem with link not being up when `IP-Config` tries to DHCP. (The client has Intel NICs, using the e1000e driver.)
17:26
Nov 24 17:24:47.687: %LINK-3-UPDOWN: Interface GigabitEthernet0/5, changed state to down
17:27
Nov 24 17:24:52.719: STP: VLAN0001 Gi0/5 ->jump to forwarding from blocking
17:27
Nov 24 17:24:54.716: %LINK-3-UPDOWN: Interface GigabitEthernet0/5, changed state to up
17:27
(I was hoping maybe the switchport didn't have portfast enabled, but it does)
17:42
<alkisg>
eddyTV: does the client boot fast with ipappend 3 or with the POST_IPXE_SED emulation?
18:52
!ipappend
18:52
<ltspbot>
