Windows Server Forum / IIS / FTP / June 2006FTP Command Line Question
Greetings, I have a FTP site (IIS 6.0) set up on port 7721. What is the command line syntax to use on a windows machine to attach to this? I tried ftp ftp.domain.com :7721 and ftp ftp.domain.com 7721 And neither works. I can ftp via command line through Unix just fine. In addition, when I try to go to ftp://ftp.domain.com:7721 via IE I get the following error: An error occurred opening the folder on the FTP server. Make sure you have permission to access this folder. Details: The operation timed out. Any help would be appreciated. Thank you. > I have a FTP site (IIS 6.0) set up on port 7721.

If the login is password protected, then send IE to ftp://username@ftp.domain.com:7721/  SignatureRobin Walker [MVP Networking] rdhw@cam.ac.uk Thanks guys for the responses. Still have about the same issue though. I can use the ftp -n and log on correctly. However, just a simple "ls" or "dir" will time out- it will never come back. Same issue using IE. I get the same error using ftp://username@ftp.domain.com:7721/ I authenticate just fine, but never get any listing of files. Now, if I use some other FTP client (CuteFTP, WinFTP) everything works great. I can upload, download, etc. The FTP server IS behind a NAT firewall, if that makes a difference. >> I have a FTP site (IIS 6.0) set up on port 7721.

I can only reconcile what you have said above if the FTP *client* is behind a NAT router, not the *server*. Your average NAT router cannot process Active PORT-mode FTP connections made to non-standard ports (i.e. other than port 21). Passive-mode connections will work to non-standard ports. Your use of port 7721 is non-standard, so NAT routers cannot do their magic. SignatureRobin Walker [MVP Networking] rdhw@cam.ac.uk Hmmm. Both the client AND the server are actually behind NAT routers/firewalls. So, does this mean that CuteFTP and WSFTP are using passive connections, whereas command line utilities and IE are using active mode? >> I can use the ftp -n and log on correctly.

Command-line FTP is active mode only. IE is supposedly configurable, but is quirky.
