Help please, I’m desperate

When I use

cx = wip_FTPCreateOpts( SERVER, evh_cx, NULL,
		  WIP_COPT_USER, DST_USER,
		  WIP_COPT_PASSWORD, DST_PASSWORD,
		  WIP_COPT_PORT, 121,
                  WIP_COPT_PASSIVE,  DST_ISPASSIVE, 
                  WIP_COPT_END);

I get problem. When I try to connect to anonumus i manage that. So problem is with OPTS user, pass or port

Hiya,

Is this a typo?

Active FTP uses TCP port 21 for commands and TCP port 20 for data
Passive FTP (which it looks like you are trying here) uses TCP port 21 to establish the link with the server, then some random port for the session.

Have a look at : http://slacksite.com/other/ftp.html (among others).

ciao, Dave

David,

It’s not a typo, but shuldn’t

WIP_COPT_PORT, 121,

set the port for establishing connection to the port on whitch my server is listening.

I’ll try to manage with teammates to server listen on 21 then I’ll post back to you what happened.

NOw, my teammates changed port to 21, and i can connect. But, this is only test server.
Now Question is there a way to set port for ftp connection? How?

Thanks

Please, if anyone knows how to set port with WIP_COPT_PORT please help.
Or where to search?

Thanks
