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
[...]
--rw-rw-rw- M 24238 ckeen   ckeen    0 Mar 14 15:44 /net/cs
--rw-rw-rw- M 24240 ckeen   ckeen    0 Mar 14 15:44 /net/dns
[...]
cpu% ndb/dns -r
dns 95194: suicide: sys: trap: fault read addr=0x0 pc=0x0001ec0a
cpu% acid 95194
/proc/95194/text:386 plan 9 executable
/sys/lib/acid/port
/sys/lib/acid/386
acid: stk()
abort()+0x0 /sys/src/libc/9sys/abort.c:6
mountinit(mntpt=0x3c754,service=0xdfffeed4)+0x70 /sys/src/cmd/ndb/dns.c:281
main(argv=0xdfffefb0,argc=0x0)+0x223 /sys/src/cmd/ndb/dns.c:200
_main+0x31 /sys/src/libc/386/main9.s:16

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

Thanks!

Christian

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?
