I don't think CVS is usually installed by default - you can find out by typing
and if it doesn't return anything, then you don't have it installed.
It doesn't look like there's a Linux binary available from that FTP server, so if you were going to download it from there you'd have to get the source and compile it. However, since CVS isn't some tiny, unheard-of application it'll almost certainly be available as a package for SUSE (using YaST IIRC?). I can't give you any pointers on how to use YaST, but I can almost guarantee that you can get and install CVS using it, and it'll be easier and more robust than getting either the source or
the binaries from the FTP site.
