Commit Message

adig: set fallback TCP port (#891)

When got a truncated UDP packet and switch the query to TCP, use the
same port.

Fallback TCP port was always default 53.

Tested on e037002. Also existed before a41b85e.

To reproduce it, on Windows:
1. Build and launch a "parrot" DNS server, which just echo back the
query with `data[3] |= 0x82`, meaning with flag truncated is true. For
example on: `127.0.0.2:33053`.
2. Launch another DNS server, on `127.0.0.2:53`. Or use a packet capture
tool, like Wireshark.
3. Run `adig @127.0.0.2 -p 33053 google.com`. You will see the log
appears on TCP port 53.

Using a non-default port DNS server, `adig @127.0.0.2 -p 33053 -t txt
gitlab.com` is very likely to trigger it, as the answer would be very
long (rcvd: 1465).
