Re: Persistent 'options' settings in resolv.conf

[tony mollica <tjm3 threedogs net>]

Dan, thanks for the reply.

I'll look into this a bit further.  I would rather use only one 
application to
get the job done although the addition of resolvconf allowed me to do
what I needed.

This small blurb turned up when I was trying to resolve a problem with
long delays at some websites, including googleearth servers.  This is
where I found the 'options single-request' entry for resolv.conf:
It works.

Not sure if the problem is the same in the thread titled
' cannot connect: because "association took too long" ', but it's worth
trying the single-request option for that problem, too, if you think it
might be an ipv6 dns problem.

Thanks,
Tony
