Hello! I have worked with Linux for just over 2 years now, acquiring many skills along the way. I'm able to use the command line (via SSH) very well, and can resolve bugs and error codes easily. I have configured most if not all of the list provided by you, including; FTP server, network interfaces (Adding additional IPv4 addresses), mail servers, SSL installations, and worked with many domain setting, and DNS configuration. Feel free to message me! :)
