I install OpenSSH on nearly all my systems for easy remote access, but until now have never been able to easily transfer files between the host & client machines.
To do this on a Ubuntu 8.04 client, install the sshfs package via
apt-get install sshfs
Then simply mount drives like this
sshfs 192.168.0.1:/mnt/stuff /mnt/ssh
192.168.0.1 is the server your connecting to
/mnt/stuff is the folder on the server you want to mount
/mnt/ssh is the local folder you want the mount to go
Thats all there is to it!
