CentOS-5.6 fuse-2.7.4-8.el5 fuse-curlftpfs-0.9.1-1.el5.rf

I am trying to mount an ftp connection as a local file system using fuse and curlftpfs. I can connect to the remote system (an HP3000 running MPEiX 7.5) and the directory seems to mount but I cannot use it. What I get is an Input/output error:

$ curlftpfs -v hahp3k01.harte-lyne.ca tmp/hp3000 * About to connect() to hahp3k01.harte-lyne.ca port 21 * Trying 192.168.1.102... * connected * Connected to hahp3k01.harte-lyne.ca (192.168.1.102) port 21 < 220 HP ARPA FTP Server [A0012H15] (C) Hewlett-Packard Co. 2000 [PASV SUPPORT]

Is this a problem with fusermount, curlftpfs the ftp server on the Hp3000 or something else?

Suggestions as to what is wrong and how I can get this to work are most welcome.
