Ubuntu change of the name of the network card

[QVENGADOR]

Hello everyone, Recently on the pc that has ubuntu when I have wanted to use it from another pc that I have on the network it launches the message that I can not access the pc with the same user. The case is that it is strange given that I have been doing it for years and it has never given me problems. Well I go into the pc of ubuntu I look at arp -a and it tells me that it has established netbios with another pc whose ip is out of my network configuration. That is to say as an example so as not to put it clearly here I have the network configured up to position 12 it would be 192.168.1.12 as a maximum because it tells me that it is in netbios with a pc with the ip 192.168.1.25
It does not stay comfortable here the network card has always been called eth0 well now it is called enp3s8
I do not know everything this gives me a bad feeling. And I would like to know your opinion.

There is a front page entry about why they have changed the names of the network interfaces. That is to say, that is completely normal and there is a technical justification behind the change.

When you say that you access from another PC, what do you mean, SSH?

My God is in everything. Thank you for the information, I thought they had pirated it.
Indeed I was referring to the use of ssh. I did not understand that netbios to the mentioned address if the router was not configured for it.
However, I still do not understand what it does by connecting through netbios at the address 192.168.1.25 if it does not exist in my network. In fact, I ping it and it does not send packets.

I am editing the post again. The fact is that if I stop the samba daemon, that address stops appearing. I will see if it is possible to do a flush in samba.

In the end I reconfigured the network and samba and it seems to have gone. Just as it came, it went. I can now sleep peacefully. Well, just a little.

Well yes, the truth is that Samba sometimes has some strange behaviors. If you only use PCs with Linux I suggest you try file transfer via SSH. Dolphin (KDE) can use it as a file system more. It is safer and more versatile than Samba. From the console you can use the scp command to copy from one machine to another. The only drawback is that you can only move by ips and domains.
