[Dnsmasq-discuss] Infiniband IBoIP support

[Moshe Levi]

Hi John,

The Infiniband dhcp is using client –id option as identifier so your host file should be
00:11:75:78:d6:7e,id:ff:00:00:00:00:00:02:00:00:02:c9:00:00:11:75:00:00:78:d6:7e,set:pxemenu,192.168.22.1,db711-02-1,1d

Let me know if that helps.

Thanks,
                Moshe Levi

Hello,

I'm trying to hand out addresses to my Infiniband adapters using dnsmasq, but doing the naive configuration doesn't seem to work. In my dhcp-hostsfile I have this entry:

ff:00:00:00:00:00:02:00:00:02:c9:00:00:11:75:00:00:78:d6:7e,set:pxemenu,192.168.22.1,db711-02-1,1d

When I attempt to bring up the ib0 interface on this node, I see this in the dnsmasq log:

717987360 available DHCP subnet: 192.168.16.0/255.255.240.0<http://192.168.16.0/255.255.240.0>
717987360 DHCPDISCOVER(ib0) ff:00:00:00:00:00:02:00:00:02:c9:00:00:11:75:00:00:78:d6:7e ignored
717987360 available DHCP subnet: 192.168.16.0/255.255.240.0<http://192.168.16.0/255.255.240.0>
717987360 DHCPDISCOVER(ib0) ff:00:00:00:00:00:02:00:00:02:c9:00:00:11:75:00:00:78:d6:7e ignored

How do I get dnsmasq to hand out addresses to these requests? My searching hasn't turned up much other than some rpms for a mellanox version of dnsmasq, which I haven't yet tried as I am hoping to just use a vanilla DNSmasq for this project.

Thanks,

jbh
