Re: ftp_nlist problem

When you do FTP its actually two TCP connections, a outgoing to port 21, and then a incoming. The most common problem with FTP is that the incoming connection gets blocked by a firewall or NAT. So most people use passive FTP where instead it makes two outgoing TCP connections. I think the directory listings are sent over this 2nd connection, so I would suggest your problem is that the incoming data connection is being blocked by a firewall on your server. Try to either use passive FTP or to change your firewall rules.

I have a script using some ftp functions that runs just fine on various server I have tested. Now that I've installed it om a customer's server, it ( obviously ) stopped working. claning the script to isolate the problem, I've discovered that the problem is on the ftp_nlist command that freezes the script execution for a lot ( and the machine too, like doing an heavy work ) and then returns an error ( false ). ftp_rawlist has the same problems. all the previous operations ( connect, login and chdir ) work without problems. any idea on where could I check for a solution? thank you,
