I see that thread has been closed as duplicate. so I don't know if there is still yet another thread I haven't seen (with possible replies) or if this is the other thread.
As for your ssh/telnet problem, is compiling them from source an option? Or is RH6.2 too old for even that to work? (If it is, maybe you could find some older source code.)
EDIT: If you don't need security (i.e. this is over a trusted LAN), and you have access to both machines simulateously, I believe you can use nc
(netcat) to do a low level file transfer. (I've never done it.)
