You are absolutely right. I should jxchecg what he wanted with telnet. The alternative to replacment for telnet is ssh and sshd (the server).
Code:
yum install openssh-server openssh-askpass openssh-askpass-gnome openssh openssh-clients
The only disadvantage ssh has is that windows doesn't have it installed by default, but one can easily install it.
The vsftd I mention above is the default and is secure. It uses the sftp protocol which is similar to https.
