hi all, i am monitoring the ports that are used by kafka server on my machine. When i do,
sudo netstat -ntp | grep 9092 it shows, tcp 0 0 192.168.122.1:9092 192.168.122.6:59158 ESTABLISHED 27413/java tcp 0 0 192.168.122.1:9092 192.168.122.1:58338 ESTABLISHED 27413/java *tcp 1 0 192.168.122.1:57821 <http://192.168.122.1:57821> 192.168.122.1:9092 <http://192.168.122.1:9092> CLOSE_WAIT 27413/java * The last entry in CLOSE_WAIT state surprises me because sudo lsof -i tcp:57821 shows COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME java 27413 root 42u IPv4 3266648 0t0 TCP sk-box:57821->sk-box:9092 (CLOSE_WAIT) indicates, that the port 57821 is owned by kafka process (pid - 27413) . Does kafka use extra ports other than listening port, 9092 to talk to itself? thanks, saravana
