Netplan/Network backend in Ubuntu 20.04 LTS

jp flag

Hope everyone is doing good.

My server is configured with static IP using netplan. I'm confused about the ubuntu 20.04LTS server network backends.

  • According to the Netplan Documentation netplan default beckend is systemd-networkd and default renderer is networkd unless changed to NetworkManager.
  • Network should stop working if I stop network service.
  • To day I have turned off all network related services for testing purpose one by one(network.target systemd-networkd.service systemd-networkd.socket networkd-dispatcher.service systemd-networkd-wait-online.service network-online.target network-pre.target) but still I can ping and ssh the machine.

Can any one help me to understand this behaviour of networking and what backend service is controlling the networking.

Thanks

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.
