Hi Stefan The port is opened and I could able to test using a sample java udp client server program. The server code ran on sample.domain.com and client code runs in my local pc.
when I run nmap -sU -p 12201 sample.domain.com, I got the below response of Starting Nmap 6.40 ( http://nmap.org ) at 2015-11-11 06:36 EST Note: Host seems down. If it is really up, but blocking our ping probes, try -Pn Nmap done: 1 IP address (0 hosts up) scanned in 4.19 seconds *if I use -Pn switch then I got the below message* Starting Nmap 6.40 ( http://nmap.org ) at 2015-11-11 06:45 EST Nmap scan report for sample.domain.com (104.214.33.xxx) Host is up. PORT STATE SERVICE 12201/tcp filtered unknown Nmap done: 1 IP address (1 host up) scanned in 2.55 seconds Thanks, Alagappan, On Wednesday, 11 November 2015 05:49:01 UTC-5, Stefan Krüger wrote: > > Hi, > > can you please try this: > nmap -sU -p 12201 sample.domain.com > is this port open? > maybe you can also create a "raw" input and send messages.. > > maybe there is a firewall or somthing like that? > -- You received this message because you are subscribed to the Google Groups "Graylog Users" group.
