Hi Henrique, Darac, list,I am currently talking with support from our firewall solution (astaro), because it seems that astaro drops the initial second query. (the A query goes through, and the AAAA query is dropped by astaro, without a log entry or other notification)
So it looks like a bug in astaro at the moment. But they're investigating... Thanks for your suggestions though! MJ On 11/07/2013 01:54 PM, Henrique de Moraes Holschuh wrote:

If you don't specify how to look up the domain, it takes a while, but if you say you want an IPv4 or IPv6 address, it's quick. In that case, I'd look at /etc/resolv.conf, /etc/host.conf and /etc/nsswitch.conf. My suspicion is that some other name service is being checked first (ldap, perhaps) and that's timing out.In that case, an strace might shed light on the issue.
