I made a mistake in my last comment above. It's not the ftp_getdata() function! It's the
data_accept() function that also needs to be updated.

I've found that you also have to update the ftp_getdata() function in the same ftp.c file. I
was able to get my version running with tony2001's patch. You have to modify it slightly for
the ftp_getdata() function. Basically, you have to use data->ssl_handle in the place of
ftp->ssl_handle. For more details see my post: http://www.deciacco.com/blog/archives/124

Hi, If any of you can help me I would greatly appreciate it. I'm trying to get into this thru
FTP and am getting the error for 550 SSL/TLS required on the control channel in CMD. As I am trying
to connect though I know it is a unix apache server. I am a "noob". Can anyone help me get
to this server with authentication please?
