Dear List,
I am currently having strange problems with my ndb/dns resolver.
cpu% ndb/dnsquery
can't open /net: '/net' dns: permission denied
cpu% ls -l /net

cpu% ndb/dns -r

ÃAny idea what's going on here? I am typing this all via a drawterm connection as user ckeen...
Thanks!

as a matter of fact, i just stumbled on part of your problem this morning.
you need to be the hostowner to start dns.
as to the permission denied problem, did you have a running resolver
before you tried to start one?

This is not as reproducible as I thought. I just opened another
window and ran ndb/dnsquery and it works now. Could this be due to
temporary dns failure problems?
Thanks,
Christian

do you have any other broken dns, other than the one you started?
