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 process may send at most, http://enterprisedt.com/questions/index.php/2838/521-internal-error 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 command sequence groups. 4xx Transient Negative Completion https://en.wikipedia.org/wiki/List_of_FTP_server_return_codes 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. The User-process is discouraged from repeating the exact request (in the same sequence). E

Solved FTP error - Firewall or something else Posted on 2006-04-20 Software Firewalls 1 Verified Solution 33 Comments 2,290 Views Last Modified: 2013-11-16 I have one client who uses a Windows 2003 member server,Titan ftp server is installed on port 521 which is ftp error configured to allow passive mode. Firewall is Symantec security gateway 360. I have created inbound security rules to allow ftp traffic on port 521 When i try to ftp from outside with filezilla as client i end up only with error "Transfer channel cant be opend" and in dos mode i am given error 425. I tried to ftp on the memberserver itself - it works and i am able to see directory listing I tried ftp error 421 from an internal machine - it works and i am able to see directory listing tried from internal machine with public ip adress and port - this works too. this means that sgs 360 allows the traffic. Only when i try from external computer with public ip adress on port 521 it give this error. Do i have to open some other ports on my sgs ? or where is it going wrong.
