Hi Stefan, nmap can't really tell if a UDP socket is open or not if the listener doesn't send a reply (which the GELF UDP input doesn't).
FWIW, I think this problem has been solved on IRC (GELF UDP input was bound to 127.0.0.1 instead of 0.0.0.0 or a public network interface): https://botbot.me/freenode/graylog/2015-11-11/?msg=53904194&page=1 Cheers, Jochen On Wednesday, 11 November 2015 14:20:49 UTC+1, Stefan Krüger wrote: > > you check TCP and not UDP ;) > try > nmap -sU -Pn -p 12201 sample.domain.com > > can you please create a RAW-Input and send some data to him, to check if > graylog works correctly and get messages? > -- You received this message because you are subscribed to the Google Groups "Graylog Users" group.
