Asset Not Being Added

[dwclarknu]

I have an IP Range scan set up to pull in anything that is live on a particular subnet. Some of the IPs that I know are live are not being detected or imported. They respond to both ping and https. In a separate scan for another subnet, identical devices are being picked up. I do have the "Save Pinged IP" box checked.

From the server, I am able to ping the devices.

The only difference I am aware of is that the devices that are not importing are on the same subnet as the Lansweeper server while the ones that are are not.

I figured out my issue. All my linux VMs had a network adapter labeled virbr0. All these network adapters have the same MAC address. Once we blacklisted the MAC addresses, the asses added with no isue.

I'd also recommend going through this knowledgebase article to do some basic checks: https://www.lansweeper.com/kb/370/no-asset-created-for-scanned-computer-or-device.html

Once you've checked the article you can also try the following:

• Enable the "Don't ping" option in the IP range scanning target as a test.
  
• Enable the "Save Pinged IP" if it wasn't.
  
• Esnure that "No SSH" is not enabled.

Is there an 'unknown' or 'webserver' asset for the IP address in LS? If so, delete the asset and scan the IP address again...

Do you have the SSH credential associated with the subnet? (or is it the global SSH credential?)

Is there anything under the 'Other Scanning Errors' report under the scanning menu?

are you running the tester from the LS server itself?

Good day!

I am having the same issue with multiple Lunux VMs. LanSweeper will not add them as an asset. When I use devicetester, the SSH credentials work with no issue. Here is the start of the SSH scan:

I have at least 35 machines with this issue that I know of. Any idea why the assets are not adding?

[jacob_bks]

what's the output for the tester, to the asset that's properly being inventoried/scanned?

[dwclarknu]

That is correct

[jacob_bks]

ok so it's the cisco UCS management console?

[dwclarknu]

Scanned it, came back as detected and having http and https open. See below

I use the connection and device tester .exe's in the lansweeper folder, from the lansweeper server itself, to see what it says... and then run them on the one that works.

if it's snmp device, sometimes devices are locked down to only certain IP addresses or object groups on that device.
