Scanning linux assets

[cheche]

Hi,
We have our workstations with dual boot and different IP, Windows-Ubuntu, now we have in Lansweeper database Windows operative systems and we try to enter Ubuntu operative systems in Lansweeper database.

I boot two computers on Ubuntu.
I run device tester OK.
I run SSH from server to clientes with credential provided OK.

Scan Ubuntu IPs, but Ubuntu assests don't appear in Lansweeper. However, Windows assets change them IP to Ubuntu IP when I search:

* Windows: e210a020h049w (172.25.20.49)
* Ubuntu: e210a021h049l (172.25.21.49)

When I search for 172.25.20.49 nothing appear, when I search for 172.25.21.49 appears Windows asset but asset IP properties are OK: 172.25.20.49.

I did another proof:

I delete Windows asset, boot computer in Ubuntu and scan it: All OK, Ubuntu asset appear.
I boot computer in Windows and scan it: All OK, Windows asset appear but, again, I must search for 172.25.21.49 IP.

Is this an unsupported configuration?

Thanks.

Most likely the Ubuntu and Windows installations are using the same MAC address. The MAC address is used as a unique identifier, when 2 devices have the same MAC they will interfere with each other. The best solution for this is to change the MAC addresses on either the Ubuntu or Windows installations. If the device has multiple network interfaces, make sure all MAC addresses are unique.


To check the MAC address on Ubuntu (look for "HWaddr"):
ifconfig -a

To check the MAC address on Windows (look for "Physical Address"):
ipconfig /all


Changing the MAC address on Ubuntu:

After you change the MAC address, delete both the Windows and Ubuntu assets in Lansweeper, then rescan them.


Also please note that having a Windows and Linux device with the same IP address can also cause these problems.
