I have linux on my machine at work and here at home. When I work from home I have a couple of options. Remote XWindows over ssh, which is pretty slow, or a local copy of the sources to work on. The best way I've found to get a local copy is to use rsync to replicate my source directory from work to home. The alternative is to use CVS to update a home copy of the code. Not only is rsync faster it also lets me work on stuff I haven't checked in yet. Because I'm syncing with my own copy of the sources I don't have to worry about overwriting other people's changes and I can either check in the code by logging in to work with ssh or just wait and do it the next day.
