Curl normally first attempts to use EPRT before using PORT, but 21with this option, it uses PORT right away. EPRT is an extension to the 22original FTP protocol, and does not work on all servers, but enables more 23functionality in a better way than the traditional PORT command. 24 25--eprt can be used to explicitly enable EPRT again and --no-eprt is an alias 26for --disable-eprt. 27 28If the server is accessed using IPv6, this option has no effect as EPRT is 29necessary then. 30 31Disabling EPRT only changes the active behavior. If you want to switch to 32passive mode you need to not use --ftp-port or force it with --ftp-pasv. 33
