A socket is bound to a port number so that the TCP layer can identify the application that data is destined to be sent.Normally
Ftp 550 I O Error Socket Closed
an FTP server runs on a specific machine and has a socket that is set socket closed error java to a specific port number. The server mainly waits and listens to the socket for a client to make a connection request. The socket closed error rdp client makes a connection request by trying to meet with the server on the server's machine and port. If everything goes well, the server accepts the connection. Upon acceptance, the server gets a new socket bound to

the same port. It needs a new socket so that it can continue to listen to the original socket for connection requests from other clients while tending to the needs of the currently connected client. On the client side, if the connection is accepted, a socket is successfully created and the client can use the socket to communicate with the server. The client and server can now communicate by writing to or reading from their sockets.
How To Fix Socket Error
A socket error can occur if one or more of the above conditions are not met or something is blocking communication between the client and server (e.g. firewall, anti-virus). Additionally, a client connection can already be established with a server when a socket error occurs such as in cases when the network connection goes down or the host that the client connected to suddenly crashed and/or rebooted. Common FTP Socket Error Codes 11001 - Host not found. Check that the hostname or IP address has been entered correctly. 11004 - Valid name, no data record of requested type.This error generally indicates that the specified FTP server name is incorrect or not specified. Try entering the hostname or IP address, not a URL (e.g. if ftp://server.domain.com/ is entered, then change it to server.domain.com). Another possibility is that connection is blocked by a firewall. Try temporarily turning off the Windows firewall or any other software firewall you are running.10061 - Connection refused. The hostname is correct, but the FTP server is not listening on the port, there is no FTP server running, or a firewall is blocking the connection.10093 - Connection failed. This can happen when the network connection goes down, e.g. the FTP server is no longer connected to the network.10039 - Destination address required. There may be a problem getting the IP address fo
SyncBackFree,use a different FTP engine and so return less cryptic error messages. Article Detail When testing an FTP connection you may receive one what is a socket error of the following errors: Socket Error # 11001, Host not found:

Also, enter the hostname or IP address, not a URL, e.g. if http://www.networkautomation.com/urc/knowledgebase/common-ftp-socket-errors/02899795-9874-19FA-89D9FA88304286FA/ you have entered something like ftp://my.hostname.com/ then change it to my.hostname.com Socket Error # 10061, Connection refused: The hostname is correct, but either the FTP server is not listening on the port, there is no FTP server running, or a firewall is blocking the connection. Socket Error # 10093: This can happen when the network connection goes http://support.2brightsparks.com/knowledgebase/articles/213469-common-ftp-errors-and-socket-error-messages down, e.g. the FTP server is no longer connected to the network. Socket Error # 10038: If you are using Serv-U modify your FTP server settings so that the following are unticked: “Block anti time-out schemes”, “Block FTP_bounce attacks and FXP”, and “Block users who connect more than 6 times within 60 seconds for 30 minutes.”. You may also want to be sure you are using a passive connection. Socket Error # 10039: There may be a problem getting the IP address for the hostname. Socket Error # 10052: The host you were connected to crashed and rebooted. Try reconnecting at a later time. Unable to connect: Connection time out: The hostname may be incorrect or the FTP server may be behind a firewall. Unable to connect. Not logged in: The username and/or password is not correct. Unable to connect. Error connecting with SSL: The FTP server does not support SSL, or you are using implicit SSL and it only supports explicit, or the wrong port number is being use

Prior to this there was no issue. WinSCP continues to work without any issues. Best Answer B Ben Spink said over 1 year ago Your ports are not open. You said they are, 2000-2100, but they definitely are not. Either the router has another place controlling this, or the OS has a firewall enabled blocking.A socket error simple test is change a CrushFTP server port to be any number between 2000-2100 and try and connect. If it works, it means the port is forwarded. If it doesn't, it proves the point that the port isn't open and can't be used for PASV mode then either.Thanks,Ben 25 CommentsOldest FirstPopularNewest FirstSorted by Oldest First Ben Spink said over 1 year ago spinkb @ Wed Jan 14 04:07:01 EET 2015Does your server work for error socket closed FTPES on our diagnostic page test?http://crushftp.com/diagnostics.jspIf not your ports aren't forwarded on your router for PASV. We suggest 2000-2100, this needs to be configured on the FTP port, and your router.Thanks,Ben Ben Spink said over 1 year ago PaulP @ Wed Jan 14 04:19:51 EET 2015Hi Ben,Thanks for the quick response. The Server does pass the diagnostic test. Should I still forward the suggested ports? Just seems odd that this was fine up until most recent Filezilla update.Kind regards,Paul Ben Spink said over 1 year ago spinkb @ Wed Jan 14 04:42:25 EET 2015Its only the latest FZ that starts using FTPES by default.So the diagnostic test passed for FTP or FTPES?Thanks,Ben Ben Spink said over 1 year ago PaulP @ Wed Jan 14 04:48:24 EET 2015Hi Ben,Apologies......Passes FTP, fails FTPS (Received fatal alert: handshake_failure).So this is why I have to configure the ports within Crush and my router?ThanksPaul Ben Spink said over 1 year ago spinkb @ Wed Jan 14 04:57:20 EET 2015We don't seem to have a test for FTPES. :( Didn't realize that until now.Do you have a PASV port range forwarded? 2000-2100? On the port and your router?Thanks,Ben Ben Spink said over 1 year ago PaulP @ Wed Jan 14 05:03:00 EET 2015Hi Ben,No, currently only port 21 forwarded on the router.ThanksPaul Ben Spink said over 1
