posted November 24, 2000 4:13 AM Hi! I'm trying to work with a FTP server that use ftpPassive=False so when I try to send a file FTP Tool send a Port command. This command should go with the IP address od the client. Well ftpTools is sending the command without the IP address in almast all cases (not in all) so the FTP server rejects the connection. I'm working with MS Proxy 2.0. Anybody knows why in some cases the FTP tool send the Port command without IP address? Thanks in advance. |

posted November 24, 2000 6:46 AM Hi! More data: I have checked the LocalAddress just before give the store command and it is OK. Why IP address is empty in the PORT command? Best regards. |

posted November 24, 2000 10:41 AM When you say "without the IP" do you mean it sends "PORT <crlf>" or do you mean it sends "PORT <wrong ip><crlf>? When we send the PORT command, we get the IP from Winsock. |

posted November 24, 2000 10:43 AM That's a weird one. If you click on the "details" button of the "About" box of one of samples, what do you see in the addesses listbox? |

posted November 25, 2000 4:52 PM I'm sorry, but I honestly don't know why it would do that. We make a string out of the local address and pass it with the PORT command. This must be some weird thing with MSPROXY. Look's like you'll have to use PASV transfers in the situation. |

posted November 25, 2000 6:24 PM Hi! But why doesn't happend with other programs FTP programs as WS_FTP? What can I do for avoiding the problem. The customer doesn't want to work with passive mode. I think too many people is working with MSProxy and Passive=False so somebody should have had the same problem. Thanks. |

posted December 4, 2000 11:23 AM Hi! I have found the following error description in Microsoft database related with MS-Proxy client " Third-Party FTP Clients Cannot Connect WinSock Proxy can only support PASV or passive FTP connections. The client informs the remote server which port should be opened. Regular FTP connections require that the client listen and wait for the server to launch subsequent connections on any port. Most popular FTP clients have a configuration option to do PASV FTP, or you can use FTP through your Web browser. " Can be this teh reason of my problem? Does anybody know how can I avoid this problem? Thanks and best regards. |

posted December 4, 2000 11:52 AM In your first message you stated that you had to use passive = false. If you set passive = true the problem would go away because the PORT command would not be used. |

posted December 4, 2000 12:25 PM Hi! Yes but the my customer doesn't to work with ftpPassive = True. So I'need a solution. Best regards. |

posted December 4, 2000 12:35 PM I'm sorry, but I don't have anything else. As you yourself pointed out, MS's solution is to use Passive transfers. |
