Hello , I'm looking for help to write a tcpdump filter that only dumps dns queries that are looking for the hostname corresponding to the IP 123.123.123.12 ... I'm thinking about something like : tcpdump udp dst 123.123.123.12 port 53 , but I'm not sure if it is correct .. any ideas and/or assistance are highly appreciated, Thanks, -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
