I have a number of ftp clients I have bought. They work for most of my client's web sites, but the ones hosted on a VPS or dedicate server give me constant errors. When I call support for these different clients, they always tell me the same thing: the problem is with the server, and of course they want me to install their ftp server on the server.
Can someone shed some light on this? Could the problem be on the servers? What can I do to get a reliable ftp connection going here?
