hi,there are some binarys on the realvnc homepage:
http://www.realvnc.com/download.html
this are for an older version of redhat, but maybe it will work. if you don't have succes, please go to any rpm serch engie (like
www.rpmseek.com) and serch for it.
of course you could try to get any connection using the pakages included on the distribution. in the documentation, you can see with wich versions of vnc it can entablish conections.
for example, im running version 4.0b4 and i can connect to windows vnc's... no problem. vnc is good.
if it does not work, try installing the tar from the vnc website. this isn't very difficult. read the documentation abbout installing.
have a while,
leg
