Re: [Pdns-users] failover LUA record
Hmmm my mistake. I assumed that the syntax for addresses for ifportup
should be the same for ifurlup. Checked on my server with version 4.6.3
and its also giving me error.
So would suggest using the ifurlup check for failover.

Strangely the ifportup line doesn't seems to work on my server. I get
"Host ... not found: 2(SERVFAIL)"
Could this be the caused by my server version, 4.4.1 ?

I suggested ifurlup because it will actually do http get request and
verify if it responds with 200 OK message. A better health check for
web servers.

Re: [Pdns-users] failover LUA record
Yes, of course http get is a better option for web servers.
Strangely the ifportup line doesn't seems to work on my server. I get
"Host ... not found: 2(SERVFAIL)"
Could this be the caused by my server version, 4.4.1 ?

Re: [Pdns-users] failover LUA record
You can do with ifportup also like this:
www.domain.com 60 IN LUA A "ifportup(443,
{{'192.168.1.10'},{'192.168.2.20'}}, {timeout=5})"
I suggested ifurlup because it will actually do http get request and
verify if it responds with 200 OK message. A better health check for web
servers.
