newbie question...

[Ron]

I know this is possible, but I am unsure how to go about implementing it.  I 
am leaving on vacation next week but there are a number of documents that I 
have on my desktop computer that I would like to be able to access while I am 
away.  I have Kubuntu6.06 with a home network set up using Samba.  How do I 
configure Kubuntu to allow me to access those files from outside of my home 
network?  I am guessing that I would have to, somehow, set up my machine as 
an ftp server but how do I go about doing this and, most importantly, how do 
I make it secure?

TIA,

Ron
