Hi,

I need to do ftp to different ftp locations of the users. It worked fine from my local machine. But when I deployed it on my server it gave SecurityError–>Error #2048: Security sandbox violation: http://myServer.com/header.swf cannot load data from myuserftp.com:21.

I kept crossdomain.xml in server root directory and its accessible with http://myServer.com/crossdomain.xml but still the security error is thrown.

Do I need to anything else on flex side like loading the crossdomain.xml on application init etc.Any ideas?

Hi rkstar,

What do you mean by writting a daemon on the server that would listen on another port for a PID? Can you please explain?

the command socket won’t get the completed response until the data socket is closed. i struggled with this for a long time and ended up writing a daemon on the server that would listen on yet another port for a PID. the PID is of the data connection and my daemon would kill it prompting the 226 response from the command socket.

the Socket.CLOSED event is never fired.

Hi,

After the transfer is complete I want to inform the user that the transfer is complete and also close the ftp connection. Can I know how to achieve it. I tried with response 226 for transfer complete but I never got it. I checked with my ftp location and the files are getting transferred without any problem.

Thanks Keith,

It worked for me. Now I am trying to do things one by one and things are fine. I changed to

case “220″ :
//FTP Server ready responce
break;
case “331″ :
//User name okay, need password
this.passWord(pass);
break;
case “230″:
//User logged in
this.changeDirectory(“/myDirectory/”);
break;
case “250″ :
//CWD command successful
s.writeUTFBytes(“PASV\n”);
s.flush();
break;
case “227″ :
//Entering Passive Mode (h1,h2,h3,h4,p1,p2).
break;
case “226″ :
break;
