DNS names not picked up by bandwidthd

Pootle · Mar 6, 2007, 4:21 PM

I have DHCP running and I have register DHCP leases and static mappings set in the DNS service page.

I can see pc names in the DHCP leases and I can connect to machines using my local domain name (iain.local) and all works fine.

But bandwidthd just shows IP addresses and only the machine with a static mapping (and pfsense itself) are identified by name.

Does the DNS relay not support reverse lookup for dhcp leases?

BandwidthD will not work in this way. It uses the ISP's dns server or whatever items that are entered into the system, general page.

Pointing the DNS at itself would be dangerous and can have unpredictable results in case that is your follow up question.

the dnsforwarder will detect a loop and shut down requests for some time (have seen that on not properly configured systems). So don't use "loopback" DNS.

Sorry I don't follow this, I'm not trying to change the DNS setup in any way, and bandwidthd is only a user of the DNS service. Surely bandwidthd could use the local (on the same machine) DNS service and not use the DNS identified to pfSense general settings.

Using nslookup on my laptop, with pfsense machine as the DNS server, it quite happily resolves the IP addresses back to names for the DHCP allocated addresses.

Surely what is needed is to be able to configure bandwidthd to use the local machine as a DNS server instead of picking up the DNS servers configured on the machine itself?

No, bandwidthd uses the standard resolver. There is no way to force it to use a different DNS server and I really don't feel like changing the C code.

Ah! OK Thanks Sullrich, one to put in the wibni list then :)
