I compiled bind9 in its own directory, but not installed.
When I run it "by itself" I get :
vjofn# ./bin/dig/dig +trace -x 204.107.90.128
; <<>> DiG 9.3.1 <<>> +trace -x 204.107.90.128

And when I force it to the local server (only?)
vjofn# ./bin/dig/dig @127.0.0.1 +trace -x 204.107.90.128

If I run it w/o the +trace :
vjofn# ./bin/dig/dig @127.0.0.1 -x 204.107.90.128
; <<>> DiG 9.3.1 <<>> @127.0.0.1 -x 204.107.90.128
; (1 server found)
;; global options: printcmd
;; connection timed out; no servers could be reached
Why does it look like its getting the answer when I trace, but
not as normal.
Thanks, Tuc
