Socket Error 10049
oldest votes up vote 4 down vote accepted What you should do is handle the Error event of the TClientSocket, because that is where you will be able to capture your socket errors. The ErrorCode parameter is the one that will have the WinSock Error code If you want to silence the Error, you can set ErrorCode to 0, which will prevent the exception from being thrown, and after that you can identify what the error is and handle it the way you want it procedure TForm1.ClientSocket1Error(Sender: TObject; Socket: TCustomWinSocket; ErrorEvent: TErrorEvent; var ErrorCode: Integer); var error : Integer; begin error := ErrorCode; {prevent exception from being thrown} ErrorCode := 0; if error = 10049 then showmessage('asynchronous socket error'); . . . end; I hope this helps Gaetan Siry share|improve this answer answered Aug 1 '10 at 19:59 G-Man 3,570124575 thanks a heap.... –Omair Iqbal Aug 2 '10 at 6:13 add a comment| up vote -1 down vote The TClientsocket component (which is deprecated for a while already) uses the asynchronous communication model, so it is possible that the exception is not thrown in the Open method but in the message / event handling method which receives the incoming data. update: I can

It is during this connection that a variety of socket errors can manifest. The socket error 10053 message is quite rare because, unlike other errors that result from a poor server connection or a problem with the server, the 10053 error comes from the computer attempting to make the connection. This is commonly caused by either antivirus programs or an application error. This type of error can also occur if the server software has not been upgraded since the 1990s. Antivirus programs and firewalls can become a constant annoyance for some users. For those who upgrade their computers often or install new software, the antivirus software or firewall blocks access because it believes the upgrade or program is malicious. While these programs shield the computer from hackers, they can also cause problems such as the
the presence of firewall or anti-virus software on the local computer or network connection. Either can block the ports needed to make a successful FTP connection to the remote server. For a regular FTP session, either disable the firewall or anti-virus software or configure them to allow CuteFTP to establish an FTP session over ports 20 and 21. Consult the documentation or help file for your specific firewall or antivirus software product for instructions. Usually the manufacturer of the device or software will also have specific instructions available on their Web site. If you continue to receive the same error after insuring ports 20 and 21 are open, contact the administrator of the site you are trying to connect to.

WSAETIMEDOUT (10060) 10060 is a connection-timeout error that usually appears when the client does not receive a response from the server for a specific command. This error often occurs when you try to connect in PASV mode to a server that prefers PORT for data connections. If you see an error log similar to the one below, in the Site Properties of the problem site, click the Type tab, then change the Data Connection Type to Use PORT. COMMAND:> PASV 227 Entering Passive Mode (xxx,xx,xxx,xx,x,xxx). COMMAND:> LIST STATUS:> Connecting ftp data socket xxx.xx.xxx.xx:xxxx... ERROR:> Can't connect to remote server. Socket error = #10060. ERROR:> Failed to establish data socket. If you still receive a 10060 error, the server may be trying to send a listing for a very large directory (with many thousands of files) causing the client to time-out while waiting. Try increasing the time-out value in the Global Options dialog box (Tools > Global Options > Transfer > Reconnect and resume in [ n ] seconds if nothing received ) to a higher value, such as 45 or 60 seconds. The connection fails due to an error or timeout. Verify that the destination IP address is correct. Increase the connection timeout threshold under Global Settings > Connection. Switch to the opposite data conn
