[gentoo-user] Suddenly, ssh is slow to connect
In the last few days, connection takes a minute or so to my gentoo box. It used to be no longer than a namespace lookup. It's not TCP, I think, because connecting to apache is fast and my web pages bet served as usual. What happened to sshd???-- Kevin O'Gorman, PhD

I'll look, but I did just change domain registrars. Maybe I've got a sluggish nameserver. But then, why would it continue to be slow when I do it a second time -- doesn't anybody cache resolutions any more? Anyway, this gives me some stuff to look at. ++ kevin -- Kevin O'Gorman, PhD

I've edited the zone file; I'll see what happens when the change propagates to the universe. ++ kevin-- Kevin O'Gorman, PhD
