Well, I had just set up pdnsd (a small caching name server) before reading
your message... since I only need caching, and none of the advanced features
of named, I think I will keep pdnsd.
Anyway, it has not made browsing much smoother. Maybe Opera has an internal
DNS cache...
I have also recompiled -Stable dating from 02/22. But after the usual "make
buildworld" and "make buildkernel", I only did "make installkernel", and
rebooted, getting a -Stable kernel on a -CURRENT world.
(I know that is not something to do, but I could not resist...)
I checked if Opera would hang: it did.
Then, I did a "make installworld", rebooted, checked Opera: it did not hang,
whatever I tried.
I am currently recompiling the latest -Stable to try the same thing, but I
will not be able post the results before tomorrow. I will try with the latest
-CURRENT as well.
So I guess this is a userspace issue, and the problem is in the difference
between -CURRENT and -Stable...
