Hi. We are running FreeRADIUS with a local patch that uses PTR record of NAS IP address instead of shortname in logs - this greatly helps with bulk client specifications like: ===================== client mgmt_net_location_1 { ipv4addr = 10.0.10.0/24 ... } ===================== And in radiusd.log we got 'Login OK ... from <PTR>' instead of 'Login OK ... from %{client:shortname}'. While looking for a proper way to `upstream'ize` this patch I came across ip_ntoh function that does resolving but does not cache results. Am I right that adding cache to this function (driven by fr_hash) and adding configuration knob for client is a good way to get rid of our local patch in favor of upstream? Any other thoughts? -- Boris Lytochkin Yandex NOC +7 (495) 739 70 00 ext. 7671
