Ntop - not reading configuration file

[pankaj]

Hi,
I've installed Ntop's community edition, using Ports and it is working fine. The Community Edition restricts the number of interfaces to a maximum of 8. Here is the information on interfaces on OPNSense machine:

Code Select Expand


root@OPNsense:/var/db # ntopng -h
Available interfaces (-i <interface index>):
   1. igb0
   2. igb1
   3. ovpns1
   4. igb2
   5. igb3
   6. igb4
   7. igb5
   8. igb1_vlan20
   9. igb2_vlan30
   10. igb3_vlan40
   11. igb0_vlan100
   12. lo0


The max limit of 8 interfaces is enough for me but the ones that I need i.e. 9, 10 & 11 are not getting picked up. So edited "/usr/local/etc/ntopng/ntopng.conf " file and added following lines:

Code Select Expand


  -i=igb1_vlan20
  -i=igb2_vlan30
  -i=igb3_vlan40
  -i=igb0_vlan100
  -i=igb4
  -i=igb5
  -i=ovpns1


The above interfaces are less than 8 but when I restart the console shows following logs:

28/Jun/2022 22:19:10 [Prefs.cpp:1951] ERROR: Hint: reset redis (redis-cli flushall) and then start ntopng again


So seems like Ntop is still using the default interface list instead of the ones specified in "/usr/local/etc/ntopng/ntopng.conf".

Does any one has any idea what I might be doing wrong here or how to make Ntop use the interfaces selectively.
Thanks,

I did some experiment in the "/usr/local/etc/ntopng/ntopng.conf " and changed the port number from 3000 to 3001.

After restart the Ntop still shows up on 3000 so seems like Ntop rc service is not reading the "/usr/local/etc/ntopng/ntopng.conf " file when starting.
