Why is Google Chrome trying to run netbiosd attempting to connect to 192.168.2.255?
Netbios searches for local services like shared files and printers. What device is at 192.168.2.255 and did you enable chrome to try to print or open files?

This could be harmless or it could be code running that you don’t want to.

The process is a helper, Apple installed it, it’s running code that google likely was told by you to run.
