I used to = use the ddns tool in openwrt to do this, but I don't think it quite does what I want. the ip tool now has json capability, yea, but basically I have rotating addresses that expire. Stuff like this: inet6 2603:3324:1536:86f0:556d:9147:97a1:290a/64 scope global temporary deprecated dynamic valid_lft 157874sec preferred_lft 0sec And other stuff that also expires but is mildly painful. I can do this to show the current primaries ip -c -6 addr show primary | grep -A 1 2603 and the same, so I can delete secondaries So I can see having a nsupdate (or linode api) script that parses this all properly and sends it "up there", or roll my own, but I was hoping for a recommendation, that does it as addresses change... --=20 Dave T=C3=A4ht CTO, TekLibre, LLC http://www.teklibre.com Tel: 1-831-205-9740
