I think you might want to use "lsof" (or your system equivalent) to find the open ports that are directly related to BIND. r...@yellow:~# lsof -i -n -P | grep named | grep IP COMMAND PID USER FD TYPE DEVICE NODE NAME named 6043 root 20u IPv6 17419 TCP *:53 (LISTEN) named 6043 root 21u IPv4 17424 TCP 127.0.0.1:53 (LISTEN) named 6043 root 22u IPv4 17425 TCP 127.0.0.1:953 (LISTEN) named 6043 root 23u IPv6 17426 TCP [::1]:953 (LISTEN) named 6043 root 24u IPv4 133746 TCP 192.168.1.125:53 (LISTEN) named 6043 root 25u IPv4 646882 TCP 172.16.33.1:53 (LISTEN) named 6043 root 26u IPv4 646884 TCP 192.168.136.1:53 (LISTEN) named 6043 root 512u IPv6 17418 UDP *:53 named 6043 root 513u IPv4 17423 UDP 127.0.0.1:53 named 6043 root 514u IPv4 133745 UDP 192.168.1.125:53 named 6043 root 515u IPv4 646881 UDP 172.16.33.1:53 named 6043 root 516u IPv4 646883 UDP 192.168.136.1:53 (output slightly edited to fit 80 columns) > is first number the total queries which asked from my server on port 53 > or number of sessions that stablished? They are useless, as your method of collecting the information did not actually gather anything that is provably related to BIND. > # rndc status > xxx... > soa queries in progress: 1 > query logging is OFF > recursive clients: 365/32668/32768 > tcp clients: 3/10000 > server is up and running > what is the meaning of recursive clinets 365/32668? > is 365 the number of queries which asked from my server or number of > sessions from other clients to me? You currently have 365 clients asking questions. > what is the meaning of tcp clients:3? Three clients are using TCP for some reason (zone transfer, truncation fall-back-to-TCP, or direct TCP queries). AlanC
