Re: Excluding hosts or a subnet from being monitored [ In reply to ]
Hi Simone,

Seem it doesn't work with my version 7.4.170109 of nprobe!

Can you show me an example, because I'm not able to do it on nprobe with the -f option.

Simone,

I found the problem: If you dont use the = sign on the filter parameter line, it doesn't see it.

Doesn't work -> --packet-filter "ip and not proto ipv6 and not ether host ff:ff:ff:ff:ff:ff and not net (224.0.0.0/8<http://224.0.0.0/8> or 239.0.0.0/8<http://239.0.0.0/8>) and not host 192.168.2.227"

Work -> --packet-filter="ip and not proto ipv6 and not ether host ff:ff:ff:ff:ff:ff and not net (224.0.0.0/8<http://224.0.0.0/8> or 239.0.0.0/8<http://239.0.0.0/8>) and not host 192.168.2.227"

That is true, I have made a fix.

The point is that when the filter is not seen, *ntopng doesn't say anything from the command line*. Nevertheless, in all your emails, you were sending us logs with ntopng showing "Packet capture filter set on ..." so it was not possible to figure out the cause of the issue. I don't know which logs you were sending but for sure they were not consistent with the claimed behavior. Next time please make sure to post logs that are actually representative.


Also, if I've eth0 and tcp://127.0.0.1:5556 as my NIC,

BPF is not supported for collector interfaces. If you want to use it then specify it on the nProbe.

it doesn't work, here the output:

Simone,

Did you run ntopng with the filter directly from the command line or via the configuration file? I think the problem happens when the filter is in the configuration file and you run ntopng to read it in this file.

Gerhard,

I've just tried to reproduce on centos6. The filter is working properly. I also tried to exclude the ntopng host and it works. So the only additional suggestion I have is to try and update ntopng to the latest stable.

Because, I've changed 10.0.0.39 for 192.168.2.227 for the test.

OK, so the filter is properly parsed. I went back through this thread and found that you complained that

The point here is that the filter doesn't contain any clause that matches host 10.0.0.39 ...

Seem that the filter passed but still can see IP 192.168.2.227 on my list!

Gerhard,

From the logs I can't see anything that confirms ntopng has read/parsed the bpf filter specified. It looks like the filter is ignored. I am not sure those logs contain the full output, though.

Can you please run ntopng in foreground and paste the output? Simply call /usr/local/bin/ntopng /etc/ntopng/ntopng.conf

Regards,
Simone

Simone,

The issue is that even if 10.0.0.39 is filtered to be excluded, it appears in the view of top hosts. Also, the IP 0.0.0.0 appaers and I don't have any idea about what it is?

The filter is correct and properly parsed by ntopng. So what is the issue you are experiencing?

Brett, the filter is not complete. If you want to exclude 10.0.50.246
set:

--packet-filter="not host 10.0.50.246"

If you look at the ntopng output you will see if the filter is parsed
correctly.

Hi,



--packet-filter is the proper way to do that. Can you please report
the
exact filter you specified? Also check (and paste) ntopng output.
ntopng
prints a confirmation message if it has successfully parsed the
filter.



Regards

Simone

Hi.



Is there any way to exclude a subnet or a range of hosts from being
monitored and appearing on the dashboard etc.



Our servers are in a specific IP range and I am not interested in
receiving their usage data.



I tried –B and –packet-filter and “not” but they don’t seem to work.



Thanks

Can you show me an example, because I'm not able to do it on nprobe with the -f option.

I found the problem: If you dont use the = sign on the filter parameter line, it doesn't see it.

Doesn't work -> --packet-filter "ip and not proto ipv6 and not ether host ff:ff:ff:ff:ff:ff and not net (224.0.0.0/8<http://224.0.0.0/8> or 239.0.0.0/8<http://239.0.0.0/8>) and not host 192.168.2.227"

Work -> --packet-filter="ip and not proto ipv6 and not ether host ff:ff:ff:ff:ff:ff and not net (224.0.0.0/8<http://224.0.0.0/8> or 239.0.0.0/8<http://239.0.0.0/8>) and not host 192.168.2.227"

That is true, I have made a fix.

The point is that when the filter is not seen, *ntopng doesn't say anything from the command line*. Nevertheless, in all your emails, you were sending us logs with ntopng showing "Packet capture filter set on ..." so it was not possible to figure out the cause of the issue. I don't know which logs you were sending but for sure they were not consistent with the claimed behavior. Next time please make sure to post logs that are actually representative.


Also, if I've eth0 and tcp://127.0.0.1:5556 as my NIC,

BPF is not supported for collector interfaces. If you want to use it then specify it on the nProbe.

it doesn't work, here the output:

Did you run ntopng with the filter directly from the command line or via the configuration file? I think the problem happens when the filter is in the configuration file and you run ntopng to read it in this file.

I've just tried to reproduce on centos6. The filter is working properly. I also tried to exclude the ntopng host and it works. So the only additional suggestion I have is to try and update ntopng to the latest stable.

OK, so the filter is properly parsed. I went back through this thread and found that you complained that

The point here is that the filter doesn't contain any clause that matches host 10.0.0.39 ...

From the logs I can't see anything that confirms ntopng has read/parsed the bpf filter specified. It looks like the filter is ignored. I am not sure those logs contain the full output, though.

Can you please run ntopng in foreground and paste the output? Simply call /usr/local/bin/ntopng /etc/ntopng/ntopng.conf

Simone,

The issue is that even if 10.0.0.39 is filtered to be excluded, it appears in the view of top hosts. Also, the IP 0.0.0.0 appaers and I don't have any idea about what it is?

Gerhard,

The filter is correct and properly parsed by ntopng. So what is the issue you are experiencing?

Brett, the filter is not complete. If you want to exclude 10.0.50.246
set:

--packet-filter="not host 10.0.50.246"

If you look at the ntopng output you will see if the filter is parsed
correctly.

Hi,



--packet-filter is the proper way to do that. Can you please report
the
exact filter you specified? Also check (and paste) ntopng output.
ntopng
prints a confirmation message if it has successfully parsed the
filter.



Regards

Simone

Hi.



Is there any way to exclude a subnet or a range of hosts from being
monitored and appearing on the dashboard etc.



Our servers are in a specific IP range and I am not interested in
receiving their usage data.



I tried –B and –packet-filter and “not” but they don’t seem to work.



Thanks

Gerhard,

BPF filters are only available for packet interfaces, not for Netflow.

Can you show me an example, because I'm not able to do it on nprobe with the -f option.

I found the problem: If you dont use the = sign on the filter parameter line, it doesn't see it.

Doesn't work -> --packet-filter "ip and not proto ipv6 and not ether host ff:ff:ff:ff:ff:ff and not net (224.0.0.0/8<http://224.0.0.0/8> or 239.0.0.0/8<http://239.0.0.0/8>) and not host 192.168.2.227"

Work -> --packet-filter="ip and not proto ipv6 and not ether host ff:ff:ff:ff:ff:ff and not net (224.0.0.0/8<http://224.0.0.0/8> or 239.0.0.0/8<http://239.0.0.0/8>) and not host 192.168.2.227"

That is true, I have made a fix.

The point is that when the filter is not seen, *ntopng doesn't say anything from the command line*. Nevertheless, in all your emails, you were sending us logs with ntopng showing "Packet capture filter set on ..." so it was not possible to figure out the cause of the issue. I don't know which logs you were sending but for sure they were not consistent with the claimed behavior. Next time please make sure to post logs that are actually representative.


Also, if I've eth0 and tcp://127.0.0.1:5556 as my NIC,

BPF is not supported for collector interfaces. If you want to use it then specify it on the nProbe.

it doesn't work, here the output:

Did you run ntopng with the filter directly from the command line or via the configuration file? I think the problem happens when the filter is in the configuration file and you run ntopng to read it in this file.

I've just tried to reproduce on centos6. The filter is working properly. I also tried to exclude the ntopng host and it works. So the only additional suggestion I have is to try and update ntopng to the latest stable.

Because, I've changed 10.0.0.39 for 192.168.2.227 for the test.

OK, so the filter is properly parsed. I went back through this thread and found that you complained that

The point here is that the filter doesn't contain any clause that matches host 10.0.0.39 ...

From the logs I can't see anything that confirms ntopng has read/parsed the bpf filter specified. It looks like the filter is ignored. I am not sure those logs contain the full output, though.

Can you please run ntopng in foreground and paste the output? Simply call /usr/local/bin/ntopng /etc/ntopng/ntopng.conf

Simone,

The issue is that even if 10.0.0.39 is filtered to be excluded, it appears in the view of top hosts. Also, the IP 0.0.0.0 appaers and I don't have any idea about what it is?

Gerhard,

The filter is correct and properly parsed by ntopng. So what is the issue you are experiencing?

This doesn't work for me, I'm using the following parameters to exclude 10.0.0.39 which is my ntopng server IP:
--packet-filter "ip and not proto ipv6 and not ether host ff:ff:ff:ff:ff:ff and not net (224.0.0.0/8<http://224.0.0.0/8> or 239.0.0.0/8<http://239.0.0.0/8>) and not host 10.0.0.39"

Thank you Simone.

I will try that tomorrow morning.

Much appreciated.

Brett, the filter is not complete. If you want to exclude 10.0.50.246
set:

--packet-filter="not host 10.0.50.246"

If you look at the ntopng output you will see if the filter is parsed
correctly.

Hi there.



Thanks for getting back to me



This is the contents of my ntopng.start file:-



-G=/var/run/ntopng.pid

--daemon=

--local-networks="10.0.50.0/25,10.0.50.128/26,10.0.50.193/30<http://10.0.50.0/25,10.0.50.128/26,10.0.50.193/30>"

--packet-filter 10.0.50.246

-m "10.0.50.0/25,10.0.50.128/26,10.0.50.193/30<http://10.0.50.0/25,10.0.50.128/26,10.0.50.193/30>"

Hi,



--packet-filter is the proper way to do that. Can you please report
the
exact filter you specified? Also check (and paste) ntopng output.
ntopng
prints a confirmation message if it has successfully parsed the
filter.



Regards

Simone

Hi.



Is there any way to exclude a subnet or a range of hosts from being
monitored and appearing on the dashboard etc.



Our servers are in a specific IP range and I am not interested in
receiving their usage data.



I tried –B and –packet-filter and “not” but they don’t seem to work.



Thanks
