Description Chris Evans 2000-09-18 23:06:40 UTC

With RH7.0, OpenSSH is installed and listens to the network on a full,
default install.

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).

One root process listening on the network is better than two....

This might be a useful thing to do in the RH7.1 timeframe or so.


Comment 1 Chris Evans 2000-09-18 23:16:35 UTC
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...

Comment 2 Chris Evans 2001-01-03 00:02:15 UTC
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.
