What are interfaces when viewing vnstat data?

us flag

I'm trying out vnstat. I can see rx (recieved) and tx (transmitted) data counts for two interfaces. Simple enough. But what are the interfaces? how can I look up what service they represent?

by flag

You can use ip or ifconfig These commands will give you detailed information about each interface, including its type, IP address, and other relevant information.

In a terminal:

ip addr show will give the ip addresses associated with the interfaces

ifconfig will give you your available interfaces

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
