Just because something has a valid > DNS entry doesn't imply it will respond to ping. What is inconsistent is that ping will not resolve the address but drill will. The only nameserver defined in /etc/resolv.conf is 127.0.0.1. We never get to the point of determining if the target replies to the ping. > > Also pkg uses SRV records, it's been discussed here before. > pkg.freebsd.org happens to be the domain that I used to test whether or not ping could resolve. I get the same results irrespective of the domain used. -- *** e-Mail is NOT a SECURE channel *** Do NOT transmit sensitive data via e-Mail Do NOT open attachments nor follow links sent by e-Mail James B.
