It sounds like their firewall is preventing passive mode by blocking inbound connections to port 5998. You can probably get peter@freebsd.org to fix that. Or, if you are not behind NAT, active mode will probably work. To select it, either use "-P a" or "-P 6666" (for example). It works like FTP, where the server initiates a connection back to the client. With "-P a" the client will listen on an arbitrary transient port. With the numeric form you can specify a particular port number or a range of ports. Your firewall will need to allow inbound connections to the relevant ports, of course. John -- John Polstra John D.
