I would not say im new at linux I have been using it for years but this is the first time that I have had to setup a server. well let me go thou the problem. I have followed http://www.howtoforge.com/perfect-server-ubuntu-11.10-ispconfig-3 to the Tee. I have setup everything that it states. I have setup a user in ispconfig with a website, and ftp account. Now the problem is I cant access the ftp account through a ftp client I have tried everything from changing from passive to active. All ports are open. I have tried both port 21 and 22 (FTP AND SFTP) but my server will just not allow me to access it. In filezilla i get this error Error: Authentication failed. Error: Critical error Error: Could not connect to server I have DMZ my router and opened both ssh, ftp and sftp ports. Im just at a complete loss apart from this the server is working. If someone could please help I need to get it up and running as soon as possible.
