If the UDP query returns TC=1 DiG retries with TCP. I want to see the UDP results and am unable to. Specifying +notcp makes no difference. The correct option is +ignore:
# dig @127.0.0.1 'web_client\;*\;athena\;*.keys.redis.sophia.m3047' txt +notcp | tail web_client\;*\;athena\;*.keys.redis.sophia.m3047. 30 IN TXT "web_client;194.55.186.216,404;athena;1670154435" web_client\;*\;athena\;*.keys.redis.sophia.m3047. 30 IN TXT "web_client;43.134.92.151,400;athena;1670132664" web_client\;*\;athena\;*.keys.redis.sophia.m3047. 30 IN TXT "web_client;35.162.155.28,200;athena;1670132664" web_client\;*\;athena\;*.keys.redis.sophia.m3047. 30 IN TXT "web_client;159.89.118.246,200;athena;1670132664" ;; Query time: 9 msec ;; SERVER: 127.0.0.1#53(127.0.0.1) (TCP) ;; WHEN: Sun Dec 04 18:42:19 PST 2022 ;; MSG SIZE rcvd: 7500 # dig @127.0.0.1 'web_client\;*\;athena\;*.keys.redis.sophia.m3047' txt +ignore | tail web_client\;*\;athena\;*.keys.redis.sophia.m3047. 30 IN TXT "web_client;80.94.92.40,200;athena;1670111034" web_client\;*\;athena\;*.keys.redis.sophia.m3047. 30 IN TXT "web_client;161.35.213.88,200;athena;1670154435" web_client\;*\;athena\;*.keys.redis.sophia.m3047. 30 IN TXT "web_client;103.10.62.92,404;athena;1670176114" web_client\;*\;athena\;*.keys.redis.sophia.m3047. 30 IN TXT "web_client;54.185.160.223,200;athena;1670154435" ;; Query time: 16 msec ;; SERVER: 127.0.0.1#53(127.0.0.1) (UDP) ;; WHEN: Sun Dec 04 18:42:26 PST 2022 ;; MSG SIZE rcvd: 1193 The "tell" is that on the footer SERVER line it reports the protocol. Note that in the first case it's TCP, even though +notcp was specified. (The MSG SIZE is also a clue.) Searching the intertubes wasn't much help. When I tried to search the list archives I got a Gateway Timeout. :-( Anyway, it's been a minor personal annoyance for a while; hopefully this helps somebody else with a problem they didn't know they had. -- Fred Morris, internet plumber
