Well funnily enough some servers won't allow passive mode, and I have seen a broken server/firewall combo which meant that passive ftp wouldn't work because the firewall denied the clients connection for passive mode (very duh). FTP passive mode works by getting the server to bind to a port and telling the client to connect to that to get/send the data, whereas normal ftp mode the client binds the port and the server connects to it. FreeBSD's ftpd allows you to specify a port range for passive ftp so you don't have to have your system wide open. --- Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
