| 16:52 | <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
| |
| 16:59 | <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 $5.69, they want to celebrate xmas too :D
| |
| 17:06 | <Monkberry> lol
| |
| 17:06 | well that was not the intention
| |
| 17:07 | <alkisg> Of course! Thanks! Don't worry about paypal's issues, I know them too well!
| |
| 17:10 | <Monkberry> I do have a strange question though and I'm not sure how to duplicate it and this might be more of a networking question. I thought the LTSP server ONLY answered on the network that the LTSP server is on. (172.16.10.*) And since I expanded the network from a class c to whatever (I now have 172.16.8,* through 172.16.11.*), I would just assign the
| |
| 17:10 | LTSP box to be on the 172.16.10.* network and all was OK. However, last night I noticed that one of the boxes booted into the LTSP with a 172.16.9.* address and I thought, how could this be? I'm not sure where or how to even troubleshoot that but I thought I'd throw it out here and see if anyone else experienced this too.
| |
| 17:11 | <alkisg> Monkberry: output of this? grep range /etc/dnsmasq.d/ltsp-dnsmasq.conf
| |
| 17:12 | <Monkberry> peter@standrews-ltsp:~$ 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

| 17:28 | Guest284 has joined IRC (Guest284!~Guest284@66.207.221.237) | |
| 17:41 | <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

| 18:36 | <alkisg> 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
