I did read that bit about the DH-1984 key exchange, which implies there is some sort or encryption being used, but didn't find any info regarding the actual encryption protocol. Now that I know what to search for I can find the documentation that states the RC4-drop3072 protocol. So, thanks for the ...

geoffsmith31

I've been experimenting with The Dude v7.15.3 on CHR. I note that The Dude client no longer has a "secure" radio button. It seems unlikely that connection security has been removed and more likely that the insecure option is no longer available. I have not been able to locate any conclusiv...

geoffsmith31

I never did get an answer to the question about the SNMP traffic with Dude agents. It seems that Mikrotik are not planning to provide this info (either they don't know, or they don't care about Dude user base). I am now retired and no longer in a position to do the following testing, but I think it ...

geoffsmith31

Mike - if you have not already figured this out: With the .Dashboard map open, Right-Click on empty space and select add sub-map. Then select the existing map that you want.

geoffsmith31

Make sure the filename extension is correct (and correct case) eg. "picturefile.jpg" is recognised by Dude as a picture but "picturefile.JPG" is not.

geoffsmith31

Have you tried device_property("Name") to return the device name?

I'm running version 4b3 on a Windows server and am using device_property("CustomField1") and device_property("CustomField2") to extract device information for use as parameters for some function probes.

geoffsmith31

You'd be better off to write a function probe to get the solution you want rather than the auto-created probes that just do the value compare as in your example. Look in the Probes thread there are heaps of examples about how to do this.

geoffsmith31

FYI - the following is the execute part of a probe that I wrote a few years ago: execute("link-test.bat",concatenate(device_property("FirstAddress")," ", device_property("CustomField2")),"c:\\snmpget") "link-test.bat" is the batch script to...

geoffsmith31

Not that I have ever known of. Dude discovery just builds a layer 3 view of what it discovers from memory (I did it once, then deleted the results as it was of no use to me). I discovered my network by starting with the switch I was connected to and mapping things out by using lldp neighbor informat...

geoffsmith31

Yes "execute on server" is definitely a working function. This is the reason that we have not been able to upgrade beyond 4b3 as since that version there is no longer a Windows server option for Dude. The syntax for the command is extremely unforgiving and there is not much help available ...

geoffsmith31

Just putting this out there without any real knowledge of RouterOS, just a bit of experimentation a while ago. I assume that the devices that move between VLANs will still have the same MAC and will be contactable by your router, so the router will have an arp entry for these devices. Can you put a ...

geoffsmith31

I've never had much success with Autodiscovery :( It just seems to give you a heap of data that isn't really related in any sort of clever way. My preference has always to manually add devices one at a time and learn how they interconnect manually. A very slow way to build a monitoring system but yo...

geoffsmith31

Salut Adrien, I'm not sure what version of Dude you are running but I run ver 4b3 on Windows Server OS. This version has an "Execute on Server" notification capability, which means that you can write a Windows script to do whatever you want when a probe goes into error. Since 4b3 Dude will...

geoffsmith31

The Dude already supports multiple IP addresses per device (well 4b3 does anyway). https://drive.google.com/file/d/0B8nO44wKEKSwS3JReGQ0elpUQnhyQVJFRUhnZ1J3YXdFbzE4/view?usp=sharing There is no built-in method to probe the second,third,fourth,etc addresses but I have written a probe that pings the s...

geoffsmith31

As long as the router has an OID that can be queried to determine the temperature - you can do this. Check out the Probes thread - there are details of how to build custom probes to generate alerts.

geoffsmith31

Change the polling times in the global settings. There is a button up in the top left somewhere that says "settings" - go to the "polling" tab. This is the default polling settings for every device. You can over-ride those settings at the device level or at the service level.

geoffsmith31

Firstly - make sure that you have the SNMP set up correctly on both switches and Dude. Confirm this by double-clicking on the switch object in Dude and open the SNMP tab, then look on the Interfaces sub-tab and see that all the interfaces on your switch are listed. Then, right-click on a blank part ...

geoffsmith31

I am in the same situation as @ChiMaster. My organisation is aware that The Dude is a critical tool for us and it is no longer being supported. We "may" have a project next year to move to an alternative and the first stage will be to investigate possible alternatives. If/When the time com...

geoffsmith31

On your network maps you can set up dependencies between devices. If a device is down then dependent devices are not monitored and therefore to not generate alerts while that "upstream device" is down. On the map, up top on the right, change from links to dependencies, to set up and to vie...

geoffsmith31

You can remove the notification at the device level. Then open the device settings, select the services tab, edit the ping service and set up the notification for that service.

geoffsmith31

If you have a notification set up, you also need to look at the notification triggers in the "On Status" window on the Advanced Tab of the "Notification". There are 5 different statuses: OK, Unknown, Unstable, Acked, Down. A notification will be sent only on the state changes tha...

geoffsmith31

Sorry - don't know how to set a default start page - apart from what I described above. Note that I am using Dude 4b3 running on a Win 2012 server - so could be different to what you see if you are running a later version on Mikrotik ROS

geoffsmith31

Probably not exactly what you are wanting to do, but I had a similar issue where I have aggregated links (ie. 2 or more ethernet connections between switches that are bonded as a single virtual ethernet interface) and want I to know if one of the individual links is down. I could not figure out how ...

geoffsmith31

What you are describing is how we use Dude in my organisation. A number of different "full" access accounts that can manage the monitoring of various systems that they have responsibility for and a couple of "read only" accounts that most people that just need to see what is goin...

geoffsmith31

Yes. Almost anything is possible with The Dude. To do what you are asking, first - create a CPU probe (using an SNMP function) that shows an error state when CPU utilisation is greater than 90% (see the Probes thread for help on creating various probes). Name the probe something meaningful like CPU-...

geoffsmith31

After Version 4 beta 3 Mikrotik stopped developing The Dude server for Windows OS. They only provide the server package for Mikrotik Router OS. Though The Dude client is still supported on Windows OS. I was investigating changing from our 4b3 installation on Win Server 2012 to the latest Router OS v...

geoffsmith31

Thanks peson. I had to add the username and password to the router object on The Dude map. I also checked the Router OS and Dude Server boxes (not sure if this is required - more experimentation needed). Now the object appearance shows the values that I expect from the ros_command function. https://...

geoffsmith31

To determine if the problem is with the function or the probe, try the following: Right-click the device icon and select appearance. In the Label section put [Cisco_SG_CPU_a()] The device icon should then show the CPU % as part of the device label. If it doesn't, then there is probably something wro...

geoffsmith31

OK - I finally got some time to get back onto this.... I have downloaded and set up CHR 6.39.2 but still no luck with this ros_command function. :( Here is what I've done: My (very basic) CHR setup [admin@MikroTik] > /ip address print Flags: X - disabled, I - invalid, D - dynamic # ADDRESS NETWORK I...

geoffsmith31

Can someone comment on this please? Getting the ros_command function to work is critical for us to be able to upgrade from 4b3.

geoffsmith31

Can someone comment on this please? Getting the ros_command function to work is critical for us to be able to upgrade from 4b3.

I think what you are referring to here is ROS functions - Not Dude functions. If I'm...

geoffsmith31

I'm also keen to be able to pass parameters into a function that I have written. It seems that this should be possible as many of the built-in functions can accept input parameters. Just that this capability is not exposed (or not documented) for user functions.

geoffsmith31

I'm trying to write some probes using the ros_command function on Dude 6.40.3 but cant get it to work. I've tried a few different commands as the parameter for the function but never see anything as a return value. Has anyone used this function successfully? If so could they please post a working ex...

geoffsmith31

I have been using The Dude for 7-8 years and have not figured out a way to do this yet. But - it would be a useful thing to have. To now I have always had to plan the monitoring map layouts so there is no more than 2 layers.
May be worthy of a feature request?

geoffsmith31

In addition to more granular user permissions, as requested by @ffrauter, could the users be authenticated using Active Directory, LDAP or RADIUS rather than just locally defined users in The Dude?

geoffsmith31

I've hit a bit of a roadblock with trying to make the ros_command function work. Not sure if this is a Dude issue or a Router OS issue but figured I'd continue this thread as it relates directly to migrating to the latest Dude. I am trying to write a probe that will read the contents of a file on th...

geoffsmith31

I have set up The Dude server on CHR in VirtualBox on my laptop and using a Win7 Virtualbox VM to run The Dude client. Most features/functions I need are still there and work as previously (from the rudimentary testing that I have done so far). However - the "execute" function no longer ex...

geoffsmith31

Thanks for the info everyone. I'll have a look at it.

geoffsmith31

Thanks for the info. What you've suggested seems like a no risk way to see what we can do to get out of our situation. Excuse my ignorance, but what is CHR? Where can I download it?

geoffsmith31

Any info on my queries from the Mikrotik team?

geoffsmith31

The organisation I work for has a fairly heavy reliance on The Dude but we are currently running 4b3 on a Windows 2012 virtual server. In fact we run multiple Dude instances (some are agents) but all on W2K12. Some of the probes, functions and alerts that we have developed over the years use the &qu...

geoffsmith31

I have not tried this but a possible workaround for the issue of The Dude not being able to accept a host name as an SMTP server may be: 1. Put in 127.0.0.1 as the IP address of the SMTP server 2. Set up an SMTP server on the same machine that is running The Dude server (hMailServer is an opensource...

geoffsmith31

OK - a NAT setup. Not a situation I have in my system. I can see why you need a Dude agent to monitor remote subnets. Windows Dude server can also act as an agent, but could be costly in licensing of Windows servers and hardware as well. Sorry - no simple answers from me.

geoffsmith31

The Dude uses SNMP (mainly) to probe the devices that you have configured for monitoring. The protocols that are used by The Dude are all supported byTCP/IP (in my experience anyway) and, so are rotable. Therefore Dude can monitor devices on any subnet so long as there is a route to that subnet from...

geoffsmith31

Here is a screenshot of the config of the RDP tool in my Dude setup. I use the /admin switch to connect to the console connection rather than a user session. Perhaps you are missing the /v option to specify the server that you want to connect to? Anyway - here is mine and it works fine.

geoffsmith31

The size of the background shape is determined by the size of what it contains. In the example you have shown I would reduce the font size of the text to make the containing shape smaller.

geoffsmith31

Tony, firstly - welcome. I'd advise against using autodiscovery, in my experience it doesn't give you anything of great value, just a logical interconnection of devices by subnets. I've always had my monitoring set up along physical interconnection lines. Makes more sense to me that way. The only wa...

geoffsmith31

We had problems with our Dude setup a while ago. One of the symptoms was maps not saving (intermittently), so deleted objects would reappear and newly created objects would not be there next time you restarted the server. Another symptom was history graphs taking a very long time (minutes) to be dis...

geoffsmith31

I had a play around with Intermapper for a while on a trial licence. It seems to do everything that I am doing with The Dude. Plus it has some other features which would be handy as well. It is almost as intuitive and simple to set up as The Dude. Unfortunately we did not have any budget for a new m...

geoffsmith31

I would put a Dude agent at each site and use that agent to "proxy" Dude probes and statistics gathering for all other devices at that site. This will keep your firewall rules cleaner I think. So only the Dude Master and the Dude Agents will need to communicate with one-another. This is gu...

geoffsmith31

The Dude will not pull the maps from a Dude agent onto the central Dude server, though this something that I would have had a great need for in a previous job. I think that this sort of feature would be great in an environment where you are monitoring multiple client's networks but you also want to ...

geoffsmith31

The graph is showing the response time for the snmp query by the look of it. In your probe definition you need to specify what it is that you want to graph for that probe. Put the OID of the counter that you want to graph in the "value" of the probe. Check the probes thread http://forum.mi...

There is no actual "save button" as far as I am aware. We had similar problems intermittently, where some stuff would revert to a previous version after a Dude server reboot. I worked out that shutting The Dude service down before rebooting the PC fixed the issue. That is - until the datab...

There is a topic on this forum from a year or two back that explains how to do what you want. I think it was related to automatically downloading graphs from The Dude.

Unfortunately your observations also apply to our network and the limitations that The Dude presents. I have tried: Argent (extremely capable and also extremely complex to set up and maintain)...

The script and associated supporting files are too large and complex to post here. Let me know your email address and I will send you the information.

geoffsmith31

Payment certainly introduces a whole other layer of complexity to the issue.

The problem we all see with it is the lack of development (at the rate we want). I think opening u...

Same issue. I have set my network equipment up so that SNMP v1 has only a READ community and SNMP v3 has both Read and Write access configured. The Dude accesses the SNMP v1 community string. This gives me all the monitoring, alerting and traffic statistics. When I want to make changes to network eq...

Dude will restart at the map you were on when you closed it - if you are a Read/Write user. If you are a Read Only user it will always start up on the same map, no matter which map you were on when you closed it down. If you want a Read Only user to start on a particular page you need to temporarily...

geoffsmith31

Dude does not have that sort of permissions granularity I am afraid. Just global Read Only or Read-Write. I have requested the sort of granularity you are talking about a couple of times. Maybe in a future release?

geoffsmith31

Here is my understanding/experience of Dude agents for what it is worth: First you set up the main Dude server, lets say in the head office part of your enterprise network. You create maps of all the things in that part of the network that you want to monitor and in the "General" tab for e...

geoffsmith31

I use Dude 4b2 and what you are seeing is tha same as what I see. I believe this is the normal behavior. If a probe goes into error it is listed on the device it is associated with and the device goes orange (or red if all probes are in error). You then have to open the device to see the error messa...

geoffsmith31

Sorry I do not have the answer but have had the same problem. I gave up relying on Web access and only enable it when needed (hardly ever). So the problem is not yours alone. My Dude is 4b2 on Win 2003 R2 server on an ESX system.

I am certainly happy to share it with you. Let me know where to send it as an email. It is quite large and complex as it does more than just send an SMS. It is the main alerting script that we use. In summary: it will send either an email or SMS to the group responsible for a particular service duri...

I have always added the links between devices manually. I used autodiscover once or twice when I first started using The Dude but only got the devices connecting to a subnet as you have experienced.

geoffsmith31

I advise you to spend a bit of time planning your map layout. You need to set up a system that is only 2 layers deep otherwise you will not see a "down" device on the third layer from the top layer. Maybe a Top layer showing your backhaul links and submap connectors for each of your tower ...

It seems that this is the intended behaviour, though in most cases an automatic UnAck when the device comes back up would make more sense.

Are you wanting to generate a syslog message when a probe is out of tolerance, or are you trying to get some sort of notification when a particular syslog message is received by The Dude?

There could be restrictions on your Email system that only allows certain classes of users t...

geoffsmith31

If the device goes blue when the link goes down then it must have been "Acked" at some stage. This is most likely causing the problem as you probably do not have a notification for when it goes from unstable->acked. Either UNack the device/probe or tick the notification for unstable->acked

geoffsmith31

It is most likely to do with the logic of your probe Error statement. If the device is down then the OID query will not be able to retrieve any value - this will be evaluated as a 0 and may end up making your error statement come out as a TRUE. I always write my probes with an if inside an if statem...

Correct. It keeps a record of the time that it lost contact (or the particular probe went down). How long it has been down and whether the outage is acive or resolved. You have to do your own calculations to figure out what time the outage was resolved.

geoffsmith31

I have not used autodiscovery, apart from trying it when I first started using The Dude 5 or 6 years ago. The results that I got with autodiscovery was exactly as described here - everything connected to one IP network cloud. I have always added individual devices and then manually set up links betw...

The Dude will keep the history of total trafic in/out on each link that you add to a map.

The data is saved in RRD style so the furth...

1. Capability to specify a "Context" for an SNMP configuration 2. Security groups (AD integrated?) to give none, read only or read/write access to different maps and tools 3. Outages on sub-maps and sub-sub-maps to flow up to the top level 4. Automatic unAck for devices/probes once theu ar...

You sure it was The Dude that automatically connected the switch links? I have a proprietary network monitoring tool produced by the manufacturer of my network equipment which does exactly that. But I have never seen The Dude automatically detect switch interconnections - only what you describe. Con...

I have tried a few things to get this sort of notification working - without success :( I have asked for this type of notification to be included in future releases of The Dude - here's hoping it happens one day. In the end I have redesigned my Dude maps so it is only 2 layers deep. My "main&qu...

My assumption, which seems to be correct, based on experimentation - is that "default" means that the standard inheritance applies. So any settings that you specify explicitly on a service will over-ride the inherited setting from the device. If you explicitly configure a setting on a devi...

I have a network with many switches that have redundant links. Some use Spanning Tree to control the redundant configuration and some use LACP. I have had situations where a redundant link will fail and I do not discover it for some time (and only by chance). I am trying to write a probe that will g...

We have a Dude system with multiple agents distributed through various network segments. My experience is that there is inheritance of settings. The service inherits settings from the device, the device inherits settings from the map it is on and the map inherits settings from the global settings. S...

I suggest making a tool that passes the IP address parameter into a VB script. Make a VB script that does the substitution of the first octet of the IP address and then calls whatever application you need using that address.

Give them Dude clients so that only the one Dude server is querying the devices, then they all connect to the Dude server to get the status of the devices. Or, maybe regularly export the map of what you want to display to a webserver that the techs have access to. Or, use the Dude web interface so t...

A very ingeneous way of creating an escalation method when none exists natively. I had been thinking about ways to do this, as I can imagine that it is something the bosses will want at some stage. I shall spend no more energy on thinking about this issue... thanks for sharing that.

It would be worth your time to have a good read through the "probes" thread in this forum. There are some very good examples of how to set up probes for all sorts of useful things.

geoffsmith31

I have created a function probe for each disk on my Win2K3 servers. This probe loggs the % of the disk used over time and also alerts you when 95% utilisation is reached. Details are below: Available: if((oid("1.3.6.1.2.1.25.2.3.1.6.3")/oid("1.3.6.1.2.1.25.2.3.1.5.3"))*100>0, 1, ...

I have a very similar requirement to what you are trying to do - my boss wants monthly statistics on our WAN utilisation (8 different sites). I looked at getting the data directly from Dude database and doing something in excel as well, but the data is not easily extracted. I did end up downloading ...

geoffsmith31

I have had this issue before and in these situations I "wrap" the probe inside a timeout probe: if(string_size(snmp_description())=0,"Timeout",(<the probe you are having issues with>)) This way, if the device is down the snmp_description function will return an empty string (zero...

Select the item (or items) you want to copy. Click the "copy" button (looks like two documents). Once you have copied the device the "paste" button will become active. (looks like a document on a clipboard). Go to the map you want to duplicate the device on and click the "pa...

The default Dude DNS probe tests for DNS resolution of mikrotik You may find that although your own DNS server is fine, there are problems upstream that are causing issues with timeout of the resolution. Try changing the probe to resolve something that your DNS server is authoritative for.

I have had to be very careful with map design to ensure I only have 2 layers of maps. Some maps are very crowded and it would be easier to understand the network if we had sub-sub-maps or sub-sub-sub-maps. Unfortunately the functionality is not there to let a down device on a sub-sub-map show up at ...

Normis, I think the issue of devices staying "Acked" in The Dude has been raised before. Can I suggest that in future development of The Dude, Mikrotik provide the ability to "permanently Ack" or "temporarily Ack". Permanent Acked devices would show green when they are ...

geoffsmith31

It most certainly is!! You can set up just about any alerting method you want - only limited by your (or others) ingenuity. There are a number of built-in notification methods (email is one of them). One method allows you to run an external script or application which allows you to do all sorts of t...

I have also had issues with high CPU utilisation on some Enterasys switches due to The Dude (and have heard of others with different types of gear). This seems to be because of the large amount of info that The Dude gathers frome every device that has SNMP probing turned on (generally a good thing -...

Regarding the Win2008 SNMP config. Have you configured the SNMP service after you installed it? Add a Read-Only community (public) and permit access to it from your Dude server (and whatever other devices you want to be able to query it) within the service configuration. You probably need to restart...

I fully agree with ste. We use email notifications for most things but use SMS for email or internet connectivity issues. We use a third-party SMS tool (SMS-IT) and a dial-up modem on a PSTN line. A 3G modem would also be a good way but I think you would need a third-party app to send an SMS using i...

I have not found versions 3 & 4 to be unusable, but there are a few things that don't quite work the way I'd like them to. In most cases I have found ways around these "limitations", however the ACK/UNACK issue described is annoying and I'm still having to manually UNACK things when th...

I had the same issue and have encapsulated the "real" probe test within a test to see if the device is responding to SNMP queries. This has solved my false positives. This is the probe I am using to test if batteries need to be replaced in an APC UPS. First it cheks to see if the UPS will ...

We had similar sort of problems when we were monitoring 300-400 devices with a single Dude machine (Win XP - I think).

From the info provided it seems that user permissions are a global setting. So a user will get the same permissions on every map. This has been my experience also. i would like to be able to set up "read only" users that have "Write" access to one or two maps. (Feature request ?)

geoffsmith31

The workaround I am using to get Read-Only users to start at the top-level map is: Create the new user as an Admin user, log on as that user and navigate to the top level map, log off then log in with my admin user account and change the new user to a Read-Only user.
