Managing and using network connectivity on a unix system

Use this tag for general questions about network connectivity:

  • configuring network interfaces
  • diagnosing network issues
  • establishing a network connection
  • etc.

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

Most questions should also have one or more tag to identify the aspect or protocol that the question is about:

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?
