I have an Apache web server running on this machine with Debian stable, this PHP program have to connect using FTP to a remote online server among other things.
Everything worked fine until I installed an FTP server (vsftpd version 3.0.3-8+b1), but I don't think this is the culprit.
vsftpd
Now I get this error
The exact error/s are:
I won't open a connection to x.x.x.x --->*remote server ip* (only to x.x.x.x ---->*my public ip*)
And can't even ls remote directories, getting this error instead:
ls
Unable to list directory
I suspect this is because FTP runs in active mode "by default" now, but I am really not sure. Those errors seems something related with passive mode.
What do you think?
The PHP routines we are talking about are: ftp_login() and ftp_fput()
ftp_login()
ftp_fput()
I think it's auto active mode because everytime I use ftp_pasv(, true) it does work fine. Didn't have to specify before.
ftp_pasv(, true)
