Computer networking is the connection two or more computing devices for transmitting and sharing data. The devices use common communication protocols over a physical or wireless connection. Use this tag for questions about managing and using network connectivity on an Ubuntu system.

This tag covers general questions about network connectivity, such as:

  • Configuring network interfaces
  • Diagnosing network issues
  • Establishing a network connection

Questions about networking between Ubuntu and a non-Ubuntu system are on-topic unless the issue is clearly on the non-Ubuntu side.

Do not use the tag if your question is specifically about a networked application and not about network configuration. For example:

  • How do I configure my Linux firewall to let FTP through?
  • How can I upload only files that are more recent than the remote version over FTP?
