Hello,
I'm trying to use ssh and netcat to forward dns queries from a
6.1-STABLE workstation to a remote 6.1-STABLE DNS server. I was
inspired by the information supplied at:
http://zarb.org/~gc/html/udp-in-ssh-tunneling.html
The methodology is elegant and simple, but I'm unable to get it
working. Here's what I've done:
local# ssh -L 6667:localhost:6667 server.foo.com
server# rndc trace
server# rndc querylog
server# mkfifo /tmp/fifo
server# nc -l -p 6667 < /tmp/fifo | nc -u 127.0.0.1 53 > /tmp/fifo
local# mkfifo /tmp/fifo
local# nc -l -u -p 53 < /tmp/fifo | nc localhost 6667 > /tmp/fifo
local# echo "nameserver 127.0.0.1" > /etc/resolv.conf
local# dig www.freebsd.org
; <<>> DiG 9.3.2 <<>> www.freebsd.org
;; global options: printcmd
;; connection timed out; no servers could be reached
I see nothing in the server's named.run file and dig reports the
server wasn't reached. Also, I'm unable to ctrl-C out of either nc
command local or remote.
What am I doing wrong?
