Note that commands marked with a * the remote server returned an error 227 entering passive mode c# are not implemented in a number of FTP servers.

- terminate the connection RETR - retrieve a remote file RMD - remove a remote directory RNFR - rename from RNTO - rename to SITE - site-specific commands SIZE - return the size of a file STOR - store a file on the remote host TYPE - set transfer type USER - send username Less common commands ACCT* - send account information APPE - append to a remote file CDUP - CWD to the parent of ftp cwd the current directory HELP - return help on using the server MODE - set transfer mode NOOP - do nothing REIN* - reinitialize the connection STAT - return server status STOU - store a file uniquely STRU - set file transfer structure SYST - return system type ABOR Syntax: ABOR Aborts a file transfer currently in progress. ACCT* Syntax: ACCT account-info This command is used to send account information on systems that require it. Typically sent after a PASS command. ALLO Syntax: ALLO size [R max-record-size] Allocates sufficient storage space to receive a file. If the maximum size of a record also needs to be known, that is sent as a second numeric parameter following a space, the capital letter "R", and another space. APPE Syntax: APPE remote-filename Append data to the end of a file on the remote host. If the file does not already exist, it is created. This command must be preceded by a PORT or PASV command so that the server knows where to receive data from. CDUP Syntax: CDUP Makes the parent of the current directory be the current directory. CWD Syntax: CWD remote-directory Makes the given directory be the current directory on the remote host. DELE Syntax: DELE remote-filename Deletes the given file on the remote host.

FTP may run in active or passive mode, which determines how the data connection is established. Active mode: command connection: client >1024 -> server 21 data connection: client >1024 <- server 20 passive mode: command connection: client > 1024 -> server http://geekswithblogs.net/hmloo/archive/2012/10/16/the-remote-server-returned-an-error-227-entering-passive-mode.aspx 21 data connection: client > 1024 <- server > 1024 In active mode, the client connects from a random unprivileged port (N > 1023) to the FTP server's command port(default port 21). If the client needs to transfer data, the client will use PORT command to tell the server:"hi, I opened port XXXX, please connect to me." and then server will use port 20 to initiate the data connection to that client port number. In passive mode, the client connects from a random unprivileged port (N > 1023) to the FTP server's command port(default port 21). If the client needs to transfer data, the sever will tell the client:"hi, I opened port XXXX , please connect to me." and then client will initiate the data connection to that sever port number. In a nutshell, active mode is used to have the server connect to the client, and passive mode is used to have the client connect to the server. So if your FTP server is configured to work in active mode only or the firewalls between your client and the server are blocking the data port range, then you will get error message, to fix this issue, just set System.Net.FtpWebRequest property UsePassive = false. Hope this helps! Thanks for reading! Posted on Tuesday, October 16, 2012 1:55
good, bad or incomplete: Range Purpose 1xx Positive Preliminary reply The requested action is being initiated; expect another reply before proceeding with a new command. (The user-process https://en.wikipedia.org/wiki/List_of_FTP_server_return_codes sending another command before the completion reply would be in violation of protocol; but server-FTP processes should queue any commands that arrive while a preceding command is in progress.) This type of reply can be used to indicate that the command was accepted and the user-process may now pay attention to the data connections, for implementations where simultaneous monitoring is difficult. The server-FTP 227 entering process may send at most, one 1xx reply per command. 2xx Positive Completion reply The requested action has been successfully completed. A new request may be initiated. 3xx Positive Intermediate reply The command has been accepted, but the requested action is being held in abeyance, pending receipt of further information. The user should send another command specifying this information. This reply is used in 227 entering passive command sequence groups. 4xx Transient Negative Completion reply The command was not accepted and the requested action did not take place, but the error condition is temporary and the action may be requested again. The user should return to the beginning of the command sequence, if any. It is difficult to assign a meaning to "transient", particularly when two distinct sites (Server- and User-processes) have to agree on the interpretation. Each reply in the 4xx category might have a slightly different time value, but the intent is that the user-process is encouraged to try again. A rule of thumb in determining if a reply fits into the 4xx or the 5xx (Permanent Negative) category is that replies are 4xx if the commands can be repeated without any change in command form or in properties of the User or Server (e.g., the command is spelled the same with the same arguments used; the user does not change his file access or user name; the server does not put up a new implementation.) 5xx Permanent Negative Completion reply The command was not accepted and the requested action did not take place.
