Network Discovery across VLANs


Recommended Posts

  • Administrators

Hi Darrell,

We scan all the local (and public if configured) networks that are assigned to your NICs. We take each IP address and subnet mask to calculate which networks we need to scan. If you provide access to other networks via static routes these networks will not be included in your network discovery.

As a NFR I think it would be better to permit identifying the ip ranges that are static routes that you wish to scan. Permit entering something like: 192.168.1.1-254, 192.168.10.1-254, 192.168.20.1-254 and then off the discovery goes across your defined VLANs.

Hi Darrell,

Thank you for your suggestion, we will consider the possibility to introduce this option into the future, but meanwhile, in order to scan other subnets, you will need to change the subnet mask on the system which is marked as a probe.

I'd also like to add that you either change the subnet of a NIC as @Chris pointed out to include the other networks or you can simply add additional IP addresses in the other networks on the same NIC just for the duration of the agent deployment procedure.

We will consider adding support for manually inputting which networks to scan.

Hi Paul,

I would like to second the suggestion for being able to manually request an IP range to be scanned.

I have quite a few clients where i would like to be able to do a probe from their domain controller that is hosted off site and on a tottally different network than the on site router (f.x. router network is 192.168.1.x and DC is on 10.100.100.1)

I have tried adding a 192.168.1.x IP to the NIC before running the probe but it doesn't work.

P.S. The on premise network is completely accessible from the DC.

      We reinstalled Pulseway on a re-imaged system and after the install we noticed issues. In the patch mgmt section, the status was "assign failed" in red. We rebooted the system and then the service was not starting. We checked the service, it was set to start automatically and in the event log it was generating this error: "Service cannot be started.  The handle is invalid"  We removed the system from Pulseway, uninstalled, and reinstalled. Service is starting normally, but still getting the same issue of the patch policy failing to assign. I tried moving the system to another group that did not have a patch policy at all and got the same result.

      I had installed Pulseway and then wanted to delete it but I was not able to find Pulseway in the control panel uninstall feature and so I tried manually uninstalling files but that also did not work. I tried running the .msi installer again but an error came up saying that Pulseway is already installed but it still was not showing up. Please help me with this.

      I am working on building an Ad Hoc report in PSA to be able to list on-hand products and serial numbers assigned to that product for inventorying purposes.
      I know the Serial Numbers are tracked, and are listed when deploying them as assets in Service Desk.  Is there a way to get that information to display in a report to possibly inventory product & serial number?

      Hi there,
      This might be a bit of a long shot - but I have an end client who's interested in deploying custom Teams issues with Pulseway (as there aren't many users in-office for obvious reasons).
      I've attempted to deploy this by pushing a batch script, to copy the backgrounds from a shared location. The backgrounds folder in question is located in the user's roaming appdata (%appdata%\Microsoft\Teams\Backgrounds\Uploads). For this reason I wasn't able to use %username% correctly in my batch script, as the script is being run by some Pulseway service, rather than as the local user account.
       
      Please let me know if you've any ideas and have a great day.
       
      Cheers,
      Joe

      Hi all,
      I hope you're having a great day and are keeping safe.
      I'm having an issue with setting up email notifications via SMTP to Office365. I've followed the document on setting Pulseway up to talk with Office365. I've also been in touch with support on this and haven't been satisfied with their answer.
      Have any of you linked this up successfully? If so, which IP addresses do you have whitelisted? Is there anything obvious I'm missing?
      I've set up a relay and can't see any attempt at mail delivery via 365.
      Cheers!
      Joe
