Since sshd and telnetd are doing very similar things, maybe telnetd should
not be listening to the network on a full, default install (because telnetd
is the unencrypted less secure service).

Oh - same goes for "rshd", "rlogind" of course.
The more listening ports we can kill (or de-priv) in the default install, the
Also, the more we encourage ssh usage over unencrypted protocols, the better...
I happily notice that RH7.1 beta1 does not have any of telnet, rsh, rlogin
listening. It just has SSH, a worthy replacement :)
Is this intentional and going to remain for RH7.1 final?
If so, we can close this bug as fixed.
Yup, it's intentional.
