<Monkberry>
hello all!
16:54
<alkisg>
Hi Monkberry !
16:54
How are you?
16:54
<Monkberry>
Hey Alkis, how are you? Do you celebrate xmas in Greece?
16:54
<alkisg>
Yes, in Dec 25
16:57
<Monkberry>
I've been trying to send you a gift but because you're not in the US, they want to whack a fee
16:58
<alkisg>
Awww thank you for the thought!
16:58
<Monkberry>
anytime
16:59
Check your email

<alkisg>
I would be nice to be able to release "xmas editions" of ltsp and epoptes as my gift to all of you, but it's more convenient to do it just before the bookworm debian freeze...
17:00
<Monkberry>
Things happen when they happen
17:00
<alkisg>
❤️ I'll convert that to a christmas gift, thank you! Merry Christmas to you too if you celebrate it!
17:01
<Monkberry>
I do. Didn't it come through as a gift?
17:02
<alkisg>
It looks like an ordinare money receipt
17:03
And paypal withheld $5.69, they want to celebrate xmas too :D
17:06
<Monkberry>
lol
17:06
well that was not the intention
17:07
<alkisg>
Of course! Thanks! Don't worry about paypal's issues, I know them too well!

I do have a strange question though and I'm not sure how to duplicate it and this might be more of a networking question. I thought the LTSP server ONLY answered on the network that the LTSP server is on. (172.16.10.*) And since I expanded the network from a class c to whatever (I now have 172.16.8,* through 172.16.11.*), I would just assign the
17:10
LTSP box to be on the 172.16.10.* network and all was OK. However, last night I noticed that one of the boxes booted into the LTSP with a 172.16.9.* address and I thought, how could this be? I'm not sure where or how to even troubleshoot that but I thought I'd throw it out here and see if anyone else experienced this too.
17:11
<alkisg>
Monkberry: output of this? grep range /etc/dnsmasq.d/ltsp-dnsmasq.conf
17:12
<Monkberry>
peter@standrews-ltsp:~$ grep range /etc/dnsmasq.d/ltsp-dnsmasq.conf
17:12
# IP ranges to hand out, usually on the internal LTSP subnet of 2-NIC setups
17:12
dhcp-range=192.168.67.20,192.168.67.250,12h
17:12
# If another DHCP server is present on the network, a proxy range may be used
17:12
dhcp-range=set:proxy,172.16.10.0,proxy,255.255.255.0
17:14
<alkisg>
Well with a 255.255.255.0 mask, the LTSP server shouldn't have given a proxyDHCP offer to the 172.16.9.* client, but I faintly recall asking about such a thing in the dnsmasq mailing list
17:14
Unless your main DHCP server also contains the boot information, boot filename etc, I don't recall if it does in your case
17:15
<Monkberry>
i don't believe it has any idea, using a pfsense firewall/dhcp here
17:19
ah maybe its the netmask
17:20
The dhcp server is 172.16.8.0 with a mask of 255.255.252.0 and it says the range is 172.16.8.1 - 172.16.11.254
17:20
easy enough to try that out

17:28Guest284 has joined IRC (Guest284!~Guest284@66.207.221.237)

<Monkberry>
That did NOT appear to have worked
17:42
peter@standrews-ltsp:~$ grep range /etc/dnsmasq.d/ltsp-dnsmasq.conf
17:42
# IP ranges to hand out, usually on the internal LTSP subnet of 2-NIC setups
17:42
dhcp-range=192.168.67.20,192.168.67.250,12h
17:42
# If another DHCP server is present on the network, a proxy range may be used
17:42
##dhcp-range=set:proxy,172.16.10.0,proxy,255.255.255.0
17:42
dhcp-range=set:proxy,172.16.8.0,proxy,255.255.252.0
17:42
I then ran #ltsp initrd
17:44
After the change to ltsp-dnsmasq.conf should I have ran #ltsp dnsmasq?
17:48
running the different restart of service appears to have been all that was needed "# ltsp dnsmasq"
17:49
I did notice that running that command did copy in /usr/:q
17:50
root@standrews-ltsp:/usr/share/ltsp/server/dnsmasq# ltsp dnsmasq
17:50
Installed /usr/share/ltsp/server/dnsmasq/ltsp-dnsmasq.conf in /etc/dnsmasq.d/ltsp-dnsmasq.conf
17:50
Restarted dnsmasq
17:51
And the relevant proxy info now appears to have changed to dhcp-range=set:proxy,172.16.0.0,proxy,255.255.0.0
17:51
Where it appears to have dropped the 3 octet of both, very cool indeed

Monkberry: hmm, that doesn't look right, it should have been 255.255.252.0 or something like that; what's the output of `ip a`, the IP part, e.g. 172.16.8.1/22 ?
18:41
When running ltsp dnsmasq, the ltsp-dnsmasq.conf file is regenerated, so any changes to it are lost
18:41
Manual changes should be placed in /etc/dnsmasq.d/local.conf instead
18:42
Or if you do want to edit ltsp-dnsmasq.conf manually anyway, then run systemctl restart dnsmasq, not ltsp dnsmasq
