and to add
fedora might not have installed telnet
you might have to install it from the dead and unsupported fedora 14 repos
currently ONLY fedora 16 and 17 are supported
If you 100% MUST use a dead version of fedora and a insecure program on a insecure "out of date" operating system
you might want to post on the
"END OF LIFE"
thread over at Fedoraforum
also from the FIRST post you are using this "su-"
That is wrong
it is "su" then a blank space and then a "dash"
then you type in your root account password
