Re: FTP commands issue

Patrik,

The reason I'm a little baffled is that the same Windows PC client (FTP.exe), is accessing different i servers with no problem.

I only seem to have a problem with this i. That's why I don't think it's a Windows firewall issue. The VPN I'm using for this connection is FortiClient. So the two possibilities I see are the VPN or the server config. So is there a way to turn off the requirement for the i to need passive mode? If not, why would it work on connections to other i's?

The network admin says that all ports are open.

If the issue is that the i side requires passive mode, how would I turn off passive mode on the server side?

This is confusing.

You're talking about i side and a server side. So far I understood that the i is the server for you and the client side is Windows?

I fail to find how to state more clearly than I already did in my message before:

Your problem is twofold:
- The standard Windows ftp client does not support passive mode — at least to my understanding. Forcing the server to negotiate a passive data connection ("quot") did not help as you've experienced.
- Probably your local Windows Firewall prohibited the incoming connection from the FTP server in active mode on your first try.

This is from my previously established understanding that you want to do an FTP transfer between your Client (Windows) and Server (IBM i).

I don't see that as an option in CHGFTPA.

Yes, because I already stated: Passive mode is negotiated ephemeral per session. Both the server and client must support passive mode. It's not something you configure globally.
