Hello Folks, Just starting using ntop. We would like to capture network statistics for bidirectional traffic and we are using "host_get_json.lua" script to accomplish this. What we are noticing is that the Tx traffic stats are appropriate, where as the Rx traffic stats are 0. We have done a tcpdump to determine if the response are being received on the interface, and they are coming in. Below is the snippet of he config file.
# Specifies the network interface or collector endpoint to be used by ntopng for network # monitoring. On Unix you can specify both the interface name (e.g. lo) or the numeric # interface id as shown by ntopng -h. On Windows you must use the interface number instead. # Note that you can specify -i multiple times in order to instruct ntopng to create multi‐ # ple interfaces. # --interface eth0 --interface eth1 # # -w|--http-port # Sets the HTTP port of the embedded web server. # --http-port 6398 # # -m|--local-networks # ntopng determines the ip addresses and netmasks for each active interface. Any traffic on # those networks is considered local. This parameter allows the user to define additional # networks and subnetworks whose traffic is also considered local in ntopng reports. All # other hosts are considered remote. If not specified the default is set to 192.168.1.0/24. # # Commas separate multiple network values. Both netmask and CIDR notation may be used, # even mixed together, for instance " 131.114.21.0/24,10.0.0.0/255.0.0.0". # --local-networks "172.25.1.0/24,172.25.2.0/24,172.25.3.128/25" # # -n|--dns-mode # Sets the DNS address resolution mode: 0 - Decode DNS responses and resolve only local # (-m) numeric IPs 1 - Decode DNS responses and resolve all numeric IPs 2 - Decode DNS # responses and don't resolve numeric IPs 3 - Don't decode DNS responses and don't resolve # -n=3 Have any of you seen this behavior. Would appreciate any help in this regards. Any pointers to FAQs would also be helpful. Regards, -- Ajit Sarnaik
