vishytr3buchet: looks like it worked for ha networks00:00
vishytrying regular network now00:00
vishytr3buchet: actually trying with a regular network and an ha network at the same time00:01
vishygutsy :000:01

tr3buchetbananas00:01
tr3buchetyou gotta see where we are in castle now00:02
vishytr3buchet: hmm there seems to be an issue with dhcp on multiple networks00:12
tr3buchetthe default gateway?00:14
tr3buchetvishy: ^00:15
vishywell00:15
vishyyou can't have a single host sending dhcp packets on the same bridge from two different addresses i think00:15
tr3buchetso you have a single bridge with 2 networks on it?00:16
tr3bucheti don't see why not, they have different macs..00:17
vishytr3buchet: eeew00:22
vishyyes i do00:22
tr3buchetvishy: ?00:22
vishyi have to give each network its own bridge i guess?00:22
tr3buchetthat worked for me00:22
*** vladimir3p has quit IRC00:23
vishyk trying again00:23
tr3buchetvishy: we don't use the dhcps so i only played with dhcp a little and i'm pretty sure when i did i must have had 2 bridges00:23
vishyinteresting00:25
tr3buchetvishy: success?00:26
vishyi wonder if it should move the eth0 ip onto its own bridge00:26
vishyinstead of the br100 bridge in this case00:26
tr3bucheti think that's the way i've got my host setup00:27
vishymight be significantly easier than trying to put two ips on the first bridge00:27
tr3buchetvishy: you're talking about the host right?00:28
vishygah00:34
vishyyes00:35
vishythe double dhcp is not working well00:35
tr3buchetIPs are on the bridges on my host00:37
tr3buchetin the lab00:37
tr3buchetvishy: ^00:37
vishyyes00:38
vishythe issue is when you bridge into an eth device that has an ip00:38
vishyit moves the ip onto the bridge00:38
tr3buchetright00:38
vishyi'm thinking it should just move the ip onto a new bridge like public_bridge or something00:38
tr3buchetoh so the network host has a different bridge for each network?00:39
vishyfail dnsmasq: failed to bind DHCP server socket: Address already in use\n00:41
tr3buchethmm00:43
vishybig fail00:44
tr3buchetyeah00:44
vishyonly one dhcp server responds00:44
vishyif it is the wrong one it goes boom00:44
vishyyou have to have each network on its own vlan or interface for this to work00:45
tr3buchetwell we are using flat right00:45
tr3buchettalking about flat00:45
tr3buchetchances are that should approximate the setup00:45
tr3buchetvishy: i wanted to ask you about your dhcp plans with ha-net00:48
vishyi'm talking about flatdhcp00:48
vishyalso probably an insurmountable issue in vlan mode00:49
tr3buchetis there a use case for flatdhcp where you have multiple networks on the same vlan or interface?00:49
vishythat is exactly what i was trying to do00:49
tr3buchetwith ha-net..00:49
vishywith either00:49
tr3buchetright i was thinking about that at lunch yesterday00:49
vishythe good news is the code works fine with one network btw00:50
vishyi should try throwing in a couple of vlans and see if it works00:50
tr3buchetwhat if each network was an alias?00:52
tr3buchetsorry had an alias on the physical device00:52
tr3buchetwrong again, an ip from each network had an alias on the physical device on the network host00:54
tr3buchetvishy: ^00:54
vishymight work with aliases00:54
vishybut i don't think so00:54
vishythe problem is dhcp packets00:54
vishythey come in on the broadcast address00:54
vishyi don't know how to make all of the dnsmasqs receive the packet00:55
vishyeff!00:57
vishythe problem was something totally different than i thought00:58
tr3buchetvishy: why not have a single instance serving multiple subnets00:59
*** jdurgin has quit IRC01:00
*** Eric_o2 has quit IRC01:00
tr3buchetvishy: so basically have multiple dhcp-ranges configured for a single instance of dnsmasq01:00
tr3buchetgood grief it's 8pm already01:01
tr3buchetalright i'm headed out for some dinner etc. yay friday01:15
