MikroTik

Hi there Mikrotik fans!

I have something to share that I've been working on for the office. When the Internet seems slow I like to be able to see who is doing what, and that is what this little Windows app does. It looks like this:

It is also extremely useful to see the traffic shaping effects when playing around with shaping rules on your Mikrotik router. It uses the Accounting feature of your router.

The tool with basic instructions is attached to this post or you can download it from the links below.

I hope this can be of use to someone! Comments welcome.

Daniel

PS: I know this is technically not a 'sniffer' but it actually started off as one so the name stuck.

EDIT:
I added a new version to this post (V1.0.3). Download the service and viewer from the links below. I had to split them because the forum does not allow files larger than 1 MB any more.
Change Log:
V1.0.3 (2014-06-24)
Download: Viewer and Service

Ability to specify service name
Use keepalive on service
Added code to help plink.exe start up the first time
Added more FAQ's to readme.txt

V1.0.2 (2014-01-15)

Added ability to track multiple subnets
Fixed and improved logging for service
Removed 'Save to CSV' button which was not working
Fixed typo in readme.txt instructions
Added some FAQ's to readme.txt

Odd, it works in my browser. The zipfile is also attached to the message if the link does not work for some reason.

Not sure I understand the question. This tool shows all traffic going through the router (Lan to Internet) and shows host names. Sounds like that is what you need?

This looks really useful, I'll give it a try and report back.

Works great, I really like it. The colorscheme is abit hard to get used to but its quite handy I love it. However if I may make some suggestions, perhaps a way to sort/filter the IP's for future versions ? You have all these columns but I can't use them to sort the list and see which user has the highest send/receive or total download...etc. Or the ability to filter, i.e monitor a few specific IP's, known downloaders and such, perhaps a list ? Anyways, great work, I've been looking for something like this for a while, and its fairly simple to get working.

edit:
you may wanna double check the numbers, for some reason its reporting some of my IP's over their 1mb limit, but I have winbox opened and its barely close to the limit

Thanks for the feedback, glad you like it! The colour scheme is the same as the one used in munin. The columns are sorted by total transfer size (sum of up and down traffic) i.e. your top users will be listed first. Active users (>= 100kbps up or down) will be marked in bold so they will stand out anyway. Our office is only 16 people so showing the 30 most active ones is really sufficient. On a Lan with more than 30 machines all IP's generating traffic are always shown but all the ones more than 30 are summed together as 'other' on the graph.

I'm surprised to hear your numbers are out because I find it very accurate. I do use a 5 second running average, however, so you will see some smoothing out. But a sustained load should be reflected quite accurately. I would be curious what other users experience.

Is it possible to add sorting by day, week, month ?

eXtremer, do you mean having a daily/weekly/monthly graph?

eXtremer, do you mean having a daily/weekly/monthly graph?

Yes.

And BTW the *.csv file isn't saved. I click save but I don't see the file.

Posted: **Thu Oct 24, 2013 6:19 pm**

Yes.

And BTW the *.csv file isn't saved. I click save but I don't see the file.

Hmm, you're right about the CSV. I actually never use it but I'll fix/remove it for a next version. Does anyone need it?

The viewer app has no history capability, only real-time. I do have a (slightly crude but working) munin plugin that will plot the same details for day/week/month/year if anyone is interested. It connects to the same service as the viewer does. Of course you will need a working munin setup.

Here you go. Note that it is written in python so you will need that too.
I'm no python programmer, so it can probably be done much cleaner. But it does the job.

The daily graph looks like this:

Is 172.0.0.1 your mikrotik? Did you enable accounting? You should get traffic info when you enter 172.0.0.1 in your browser.

Hi Daniel
Tnx for this program.. works great..
I need more of these tools..
Indeed also for Saving and monitoring for month statistics.. per user, or per IP...
Keep up the good work
Do you have a website , where we can follow this ?
Tnx

JP

Posted: **Tue Dec 17, 2013 7:58 pm**

thx danielm, this tool working great here.

Can you make this tool to accept different subnet too?
I want to capture for ex. 192.168.0.0/24 and 10.100.100.0/24

Posted: **Wed Dec 18, 2013 11:27 am**

JP,

Glad you like it. To keep track of monthly usage you can set this setting in the SnifferService.ini file:

ClearSchedule=monthly

This will store the usage for the whole month (instead of just one week) and also write out a CSV file i.e.
201312.txt (yyyymm.txt) in the service folder.

Sorry, there is no website at this time.

Daniel

tnx for tip..
the Save File does not work.. like said, one can choose a folder, but nothing is saved..
Would there be an update ?
Tnx in advance
JP

Posted: **Wed Dec 18, 2013 2:53 pm**

JP,

I'd rather remove that feature since it saves the values as "34.66 GB and "12.34 MB" instead of byte values. Best would be let the service create the file.

Anything is possible

I'll see if I can add capability to accept comma delimited values for network and mask.

This is a great utility, just what i needed.
Is it also somehow possible to see the hosts name, next to the Ip address (in my case the hosts name dont always show up)?
Also how do i now disable the logs in mikrotik router, for the ssh sniffer user ( now my logs are full with the "sniffer" user, log-in and log-out?

Thank you

imaljko4,

If you use DHCP and/or DNS on the mikrotik the host names should show (that is what you see in the logs - the dns entries being downloaded)
Not sure how to disable logging in mikrotik

Hi ircome

Did you manage to get http://192.168.88.1/accounting/ip.cgi to show in a browser? If so how because I have the same problem at a particular site where hotspot is used and I don't know how to get around it (I cannot access the mikrotik accounting page from a browser or from the sniffer)

You are wright, the host-names do show up, just they sometimes get lost when my server-computer(with sniffer service running) resumes from standby.
So when my computer resumes from standby i had to stop/start the sniffer service, and then i got the host-names again.

Thanks

One more question; is it possible to monitor Ip addresses for 2 networks?

On my Mikrotik router i have :
network 1 : 192.168.1.0/24
network 2: 10.0.0.0/24

I would like to monitor Ip addresses on both networks.

So how do i need to change the values in the SnifferService.ini file?
Something like this or?

#Capture packets from this network (ignore internal traffic) - network 1
Network=192.168.1.0
Mask=255.255.255.0

#Capture packets from NETWORK 2

Network=10.0.0.0
Mask=255.255.255.0

#Mikrotik Server
Mikrotik=192.168.1.1
MikrotikSSHUser=sniffer
MikrotikSSHPassword=XXXXX

Thank you for help

It should refresh every 5 mins. Just give it a while.

Now you can

. I have added this feature and added all the info below to the first post of this thread.

Changes are

Added ability to track multiple subnets
Fixed and improved logging for service
Removed 'Save to CSV' button which was not working
Fixed typo in readme.txt instructions
Added some FAQ's to readme.txt

Tested on 3 different Windows 7 machines and all I see in the log is:

2014/01/16 12:26:07 - Info: Starting up sniffer service
2014/01/16 12:26:07 - Info: Mikrotik user: sniffer
2014/01/16 12:26:07 - Info: Mikrotik IP: 172.16.0.1

Then nothing in the viewer. It doesn't seem as though the SnifferService.exe continues running after that point?
Is there any way to see more debug info?

Posted: **Thu Jan 16, 2014 8:37 am**

omega-00,

There are a number of checks described in readme.txt that you can do. Basically you want to check:
- you can access the traffic info on the mikrotik from a browser running on the machine where the sniffer service runs
- when you start the service you want to see that the user 'sniffer' logs in on the mikrotik (check mikrotik logs)
- then check you can see traffic and ips using a browser to connect to the service
- then start the viewer

Does the service crash at that point or is it still running?

Posted: **Thu Jan 16, 2014 7:55 pm**

Tnx Daniel and Happy 2014
Love this new version... works great, monitoring 2 network segments..
Keep U the good work
JP, Antwerp

Posted: **Fri Jan 17, 2014 3:24 am**

- can access the traffic page from the machine running the sniffer service (http://ipaddress/accounting/ip.cgi loads, can see traffic listed)
- can't see user 'sniffer' login to the mikrotik (user account is present on the mikrotik) no user login error shows in the log either
telnet and ssh are available from the machine running the sniffer service to the mikrotik

service crashes before the login process it seems.
I run avast antivirus/security suite on my machine but tried disabling that before starting the service too to ensure it wasn't trying to block/intercept anything.

Posted: **Fri Jan 17, 2014 8:32 am**

Firstly, is plink.exe available in the same folder as snifferservice.exe? Can you execute it successfully from command line?

Otherwise it may be a config issue - the app does not tolerate an invalid config very well (I guess I can improve that at some stage). Can you perhaps post your snifferservice.ini file?

Can you make sure that the sniffer service is running (after install i had to manually start the "sniffer service" under control panel- "services")?
Also can you access the http://ipaddress/accounting/ip.cgi page?
if yes, then "danielm" will have to help you out

But would be good if you can also post the "SnifferService.log" file.

Mikrotik=192.168.80.1:8292

I see a problem. The 'mikrotik' setting does not support a port. At the moment it defaults to port 80.

Edit: it defaults to port 80 for web traffic and port 22 for ssh.

Hello danielm foremost appreciate your response.
I mention that I changed the port Mikrotik Web service, from 8292 to 80.
I verify that I can access via browser http://192.168.80.1/accounting/ip.cgi

With the following results:

I also keep seeing in the log file indicating that the line can not run the program plink.exe located in the same folder as SnifferService.exe

Of course I appreciate your comments

lucianog,

Please try the attached service (just replace the existing exe file). It has some extra debugging info. Upload your logfile again.

Hi Danielm:
This is the information requested:

Thanks in advance!

SOLVED!!
Hi Danielm
The problem was on the SSH port, I changed it to 222 of 22

Thanks for the support!

Weird, im my conf, it works fine with other port other than the default just like lucianog's conf

Hmm, it turns out you can indeed specify a port in the .ini file. It is used for http but ignored for SSH (by plink.exe). So if you specify 192.168.88.1:8080 it will be used as follows

- to get traffic, sniffer will connect to http://192.168.88.1:8080
- to get DNS and DHCP, sniffer will connect to 192.168.88.1:22 using ssh

So you MUST use port 22 for SSH (in the current version), as lucianog discovered

service crashes before the login process it seems.
I run avast antivirus/security suite on my machine but tried disabling that before starting the service too to ensure it wasn't trying to block/intercept anything.

Omega-00, do give the updated snifferservice.exe a try. If it still fails you can execute plink.exe from the command line using the same parameters as in the logfile to see what results you get.

Hello. Can you create a list with the names of host? how works the ips.txt file? Thank you.

Easiest and best option is to add them as DNS entries on your Mikrotik. The app will then display them correctly if the ssh setup is done as described in the readme.

Alternatively create a file and specify it in IPSource entry for Sniffer.ini
i.e. ips.txt

192.168.1.1=firewall
192.168.1.2=server1
192.168.1.20=my pc

However, this would ignore all DNS and DHCP info from the mikrotik server.

plink.exe does the ssh comms with your mikrotik.

Try to run it from the command line e.g.:
plink.exe sniffer@192.168.88.1

You should be able to connect to the mikrotik.

Hello everyone.

I'm a French student in computer networks and I must admit that you have done an amazing job.
Nevertheless, I would like to know if there is a possibility to export a daily basis of the real time capture without using munin ?
The goal is to find which IP uses more bandwidth in the day.

If you know any other scripts/tools/programs that can do that, I'm interested !

Thank you everyone and goodbye !

Posted: **Tue Apr 29, 2014 6:31 am**

Hi Daniel,

I am so happy that I found this tool you made. Thanks for your effort, great effort

It's the tool which I've been searched for a while, and now I found it.

I successfully set this tool on my computer, and the service runs well.
I just do not have understanding about the munin plugin you post. How does that plugin applied to the tool?

Please enlighten me.

Again, many thanks for your great effort

Cheers

I have a small request seeing that we have multiple mikrotik devices can you make it so u can install the service as another name so we have unique instances of the service running to "segment" the bandwidth? thanks.

I'm using the new snifferservice.exe.

Executing/logging in via plink.exe manually works fine. Gives me the MT command prompt as expected.

Executing the new snifferservice.exe just generates the following 3 lines; from command line the app appears to start then stop straight away.

You can just interrogate the sniffer service using rest to get realtime traffic info. Just go to the snifferservice ip address using a browser. The headers are at the top.

Hi Daniel, been trying to get it to work on my RB750UP, but it is set up as a basic Switch (bridge) not using DHCP etc, should it still work somehow? Is there any extra settings I need to consider?

I note you say in the file "The setup works best when you use the miktorik router for DCHP and optionally DNS" ... so it gives me hope it may still work for me??

OK, I have finally found the trick to get plink.exe working. The problem lies in the fact that plink does not yet trust the ssh connection to the mikrotik box. The first time you connect plink asks you to add the host key to your registry and you must answer yes.

SO, open a command prompt and execute the following command from your snifferservice folder (specify the mikrotik router ip):

plink 192.168.88.1

The output looks like this:

C:\Program Files\Sniffer\Service>plink 192.168.88.1
The server's host key is not cached in the registry. You have no guarantee that the server is the computer you
think it is.
The server's dss key fingerprint is:
ssh-dss 1024 xxxxxxxxx
If you trust this host, enter "y" to add the key to PuTTY's cache and carry on connecting.
If you want to carry on connecting just once, without adding the key to the cache, enter "n".
If you do not trust this host, press Return to abandon the connection.
Store key in cache? (y/n) y
login as: sniffer

That's it. Just Ctrl-C to exit. Now restart the sniffer service and confirm you see the user sniffer log in to the router.

Richard,

If you don't use DHCP that should not be an issue - you just won't see names next to the IP's. your problem lies in the fact that you cannot access http://192.168.178.14:80/accounting/ip.cgi. If you can't then the sniffer can't. I assume 192.168.178.14 is your mikrotik?

The munin plugin is just to keep track of traffic for longer than 100 seconds. Draws graphs etc. If you are not familiar with munin i'd give it a skip.

You need to specify the custom http port 81 in the following setting in snifferservice.ini.

The setting 'ServicePort' is for the sniffer service to listen on a different port than 80.

as I am using hotspot on LAN interface so port 80 is used by my hotspot and I have changed router service port to 88.
so my accounting address is http://192.168.0.1:88/accounting/ip.cgi and I can see log in my browser. So I have changed accounting path in services.ini

AccountingPath=http://192.168.0.1:88/accounting/ip.cgi

..and its working now thanks
just a quick question how can I see a whole month log at once ?
Glad its sorted. The accountingpath gets appended to the ip address of the "Mikrotik" setting.

Do you mean the whole month as a graph or the whole month in text (how much data per ip)?

whole month as a graph, and is there any way to record the websites users view, as I am using Radius so sorry to say that but radius is doing all the job of accounting and loging of user data per session and I have almost 3 years data per user now in my radius I was kind of searching some thing that can record or show what websites users visited (this is now required due to government policy for all WISP to keep 1 year record of user activity).

For a graph you'll have to take a look at the munin script I posted earlier in this thread. It talks to the snifferservice and plots the info of 30 most active users (per IP). But you'll need some experience with munin and linux. As for the visited sites I'm afraid I can't help.

Win machine is needed running 24/7?

Only if you need accurate values for the amount of data transferred per ip for the week. You might also notice a spike in measured traffic when the service starts up due to the build-up of accounting data. Other than that no issue.

Dear danielm,

Thanks for this awesome utility. I install it a month ago, its works fine.
Now i enable Mikrotik Web Proxy(transparent mode) and i observe that the tool doesn't show me the real bandwidth utilization of users.
Do i need to made some changes to work with Web Proxy?

thanks in advance.

Hmm, when you use a web proxy the traffic does not go through the router as normal, instead it terminates on the router and the router makes a new connection to the internet. I'm not sure how this is handled in accounting. (You can try switching on 'account local traffic' in accounting perhaps?)

What I can tell you is the logic in the sniffer. For the sniffer to count a packet the source must be local (according to the specified network and mask) and the target must not be local. Or the other way round. If both are local (or both are not local for some reason) it is not counted because we are interested in Local -> Internet traffic.

Posted: **Sat Jul 05, 2014 6:44 am**

Dear danielm.

Thanks for your brief reply. I have tested it with "account-local-traffic=yes" but no such success. as you mentioned, traffic redirected to proxy doesn't count.
for my understanding is it possible to count the per ip traffic on a particular interface (i.e LAN) with dst-address=!local for upload and dst-address=local for download.
As TORCH tool does on an interface(i think its also using ip accounting, but not pretty sure

).

Thanks and regards,

OK, let's do an experiment. If the mikrotik accounting reports the traffic from the LAN to the router then we can show that. I have added some logic to do that. Grab the service attached below and specify

MeasureTrafficToRouter=1

in the ini file. Also set account-local-traffic=yes on your mikrotik.

It should show all traffic going through the router as well as LAN traffic to and from the router.

I have not tested this yet so no guarantees

Let me know how it goes.

How can i use your tool for monitor everything?

Skyflash, glad you like it. Note this comment in snifferservice.ini:

#Capture packets from this network
#Comma-separated values are accepted.  Specify a mask for each network even if they are the same.

So for you that would mean

Network=192.168.1.0,192.168.2.0,10.0.0.0
Mask=255.255.255.0,255.255.255.0,255.255.255.0

LineCapacityOutbit=512000

All is functioning now, thank you for the great tool.

I have downloaded both he service and viewer files.
Created the SSH user & group on the MT router enabled accounting, set the web access accepted IP.

When i access the router VIA http://10.0.0.1/accounting/ip.cgi.... The browser displays the following in example.

Highly unlikely. Your router must provide accounting info on http in this format (at the very least):

23.57.219.27 192.168.21.46 52 1 * *

Check your mikrotik log. You should have an SSH connection or at least a connection attempt every 5 minutes from the 'sniffer' user. Maybe you see a logical error. Also check the snifferservice log file.

Nice idea but will take a while to implement. Maybe some time in the future.

I have seen the graph becoming corrupt but have not been able to find the cause. On the other hand I have had the viewer run for weeks without issues too. If you can figure out under what circumstances it happens it would be very helpful. (Of course restarting the viewer sorts it out but it is a bit of a pain.)

this tool is pretty awesome i must admit i like it alot

i have but one question

is this tool grabbing data written to the routers memory or is it polling and collecting data in real time

the question i ask is if i was to turn off the machine with the service running.. if i was to turn it off and go to work and come back and fire it back up will it have account the data from when it was turned off or will it just start logging from there ? im looking for something that will look but do the same thing that your system does without having to have a machine on 24/7

this tool is awesome and you should be really proud of your work

Great works you did. BTW, I'd like to ask if you will release the source or not? I think this is a great idea to enrich more functions for this app. For my personal opinion, I think it should at least have a column for connect manually instead of store the server address in a INI file. And also it should use the per-user config store to save last connect address. Since it's the first time I try the app, but I already got lots of idea to improve it. I'm afraid some of my idea will conflict with your original intention. So I think it will be better for you to publish the source in some repository(like github, sourceforge etc.) and then people can develop different version for different purpose. But if that's not quite possible to release the source, would you like to write some documents to describe the protocol between server and viewer? Thank you!

I've already tried this and its work amazingly.
but why cant i see the hostname (in my case)
can you help me with it?

Posted: **Sun Apr 19, 2015 11:16 am**

I've got the same problem. It works great but doesn't show hostnames. I'm using DHCP on my MT. I've tested on 2 MT's with the same effect.

Usually it takes few minutes for the hosts to appear.

Check in your log on the mikrotik router if you see the "sniffer" user connecting ?(if all works fine, you will see the "sniffer" user connecting constantly in your log).
If it doesn't show in the log, then something is wrong...

See the picture.

Can i monitor 2 different mikrotik routers on the same server ? ( 1 service running with 2 servers or 2 services running with 1 server each ?)

I am able to monitor 2 different routers on the same computer.
I had to install/run 2 services (had to rename the 2nd service to "sniffer2"), and then i used 2 viewers, each viewer is setup to connect to one of the services.
Then it works

So " viewer1" is connecting to "snifferservice1"
"viewer2" is connecting to "snifferservice2"

You have to set this parameters in the snifferservice folder "snifferservice.ini" file
and in the viewer folder on the "sniffer.ini" file

Hi, Thanks for the programs, it look like Awesome.

Try to type this link in your browser and see if you can access it: http://192.168.1.1/accounting/ip.cgi

instead of the "192.168.1.1" you put your router ip address.

If you cannot acces that page, see if you have enabled accounting under: winbox- ip- accounting
and check if you have enabled http access to your router under: winbox- ip - services (here the port 80 must be enabled for access)

Posted: **Tue Jun 02, 2015 4:57 pm**

Yep, I could see the Mikrotik telling the connections in an plane text interface, and restarted the windows service many times. (the service port is set in the 80, I don't have any other service in this port in this computer)

Posted: **Tue Jun 16, 2015 10:28 pm**

Hi,
got this working except I cant get the viewer to use port 85 ??? cant use 80 already in use
I can see the data so the sniffer works, just the viewer I have used 192.168.x.x:85 no go ?

Hi All

I wonder if someone can help me. I followed the instructions below to create the sniffer user for the monitor, I logged out of the router and thereafter I could not login as admin anymore. I have restarted the routerboard but no joy. I am desperate to get back in as admin. Did anyone else experience this? Any suggestions at all?

Thanks

On Mikrotik
-----------
Create an SSH user for getting DHCP lease names and DNS entries
/user
group add name=sniffer policy="ssh,read"
add address=192.168.88.0/24 disabled=no group=sniffer name=sniffer

Enable accounting, required for graph
/ip accounting
set account-local-traffic=no enabled=yes threshold=2560
/ip accounting web-access
set accessible-via-web=yes address=192.168.88.XX/32
(XX is the IP of the Windows machine where SnifferService will run)

check on http://192.168.88.1/accounting/ip.cgi that it works (from specified machine)

Posted: **Mon Jul 13, 2015 11:02 am**

HI, thanks again for your software, do you know how many ip-s (computers) can the viewer show at once on a network. My network has about 50 computers connected, but seems that the viewer will show only up to 33 computers, or am i wrong?
Do you know if i can somewhere specify that the viewer shows more than 33 computers (actually all the computers that are connected to the network) ? thanks

Posted: **Mon Jul 27, 2015 4:55 pm**

Is there any way of overriding the default ssh port 22? To avoid brute force attacks, my Mikrotik is set to a different port.

The ini.file's port setting only overrides web, not SSH access. I tried changing the server to 192.168.1.88:5005, but that does not seem to register.

Any guidance much appreciated!

Hello,

First I have to thank you for providing this tool. I would like to ask whether I can put the service on another PC (192.168.168.250) and run the viewer from my notebook (192.168.168.124)? If its possible can you show me what I should enter on the viewer config file. Also, is it possible to save the traffic by day, maybe to a csv file?

Thanks.

Hello guys,

it seems i have a problem here which i cant completely understand and fix it..

I used the sniffer perfectly until today...Today i renabled my transparent web proxy which redirects all the port 80 traffic to port 8989. As soon as i did that the sniffer stopped working. I checked the accounting from web and browser sends back a 401 error (anauthorised access). It seems that the proxy doesnt authorise the accounting, but my sniffer is configured on port 249 (random port i assigned when i first set it up, coz port 80 was blocked).

How can i bypass it?

EDIT : i created 2 address lists in firewall, all the network range exluding mine and i created 2 nat chains with both lists in each redirect. Now all the hosts in the network go through the proxy apart from my pc. Is there another way to have both proxy and accounting?

I'm having problems seeing traffic in the viewer and looking for help.

I can see traffic if I go to the address: http://192.168.0.1:81/accounting/ip.cgi
I can see information in the traffic.txt file
The log file show's me logged in with no errors.

I'm not using port 80, I'm using port 81 and have change the web access port on the MT to port 81.
(This solved the error

Error: Cannot get traffic: Connect timed out. (192.168.0.1:81)

I was having by the way)

anyone got any advise?

Posted: **Fri Sep 18, 2015 3:08 pm**

Solved: After I changed ports from 80 to 81 I forgot to change the port number in sniffer.ini as per readme file.

Viewer on Windows machine
-------------------------
- Copy the Viewer files to your machine (any windows machine on the LAN)
- Configure sniffer.ini as per comments (add a port number to the ip if you are not using port 80 for the 
  SnifferService, i.e. SnifferService=localhost:81)
- Start up SnifferViewer.exe

Posted: **Tue Sep 29, 2015 11:51 am**

I have Windows 8.1 for some reason I can't see service running in task manager. and I get error when I start the viewer up Invalid floating point operation

Same issue with me running the viewer, any clue on resolving the isssue?

*edit*

Thanks BroganOs, specifying the alternate port in the Sniffer.ini (host:port) solved my client crashing too...

In snifferService.ini try changing the "Network" address to the address of your router which I'm assuming is 192.168.0.3 and put the new service port number at the end of the IP address under the microtik server ( see example below)

#Capture packets from this network (ignore internal traffic)
#Comma-separated values are accepted.  Specify a mask for each network even if they are the same.
Network=192.168.0.3
Mask=255.255.255.0
#Match everything BUT the above (only for special custom situations):
InverseMatch=0

#Mikrotik Server
Mikrotik=192.168.0.3:2560
MikrotikSSHUser=sniffer
MikrotikSSHPassword=sniffer
#This is combined with the Mikrotik IP address to create the accounting URL:
AccountingPath=/accounting/ip.cgi

#Alternative service port to listen on
ServicePort=2560

If you cannot acces that page, see if you have enabled accounting under: winbox- ip- accounting
and check if you have enabled http access to your router under: winbox- ip - services (here the port 80 must be enabled for access)
