Working as designed.

Telnet and ftp are insecure, and are not loaded/enabled during normal installs.

login id and password is passed as clear text and can
be snatched with a packet sniffer off both ends of the connection.

Use ssh/sftp instead.
Be sure to get the lastest from your distribution vendor.

If using, windoze get Putty.

But if you realy want to use it:
man xinetd
man hosts.allow
man tcpd

Himba,

Rename /etc/securetty to /etc/securetty_orig to enable root login via
telnet or you can add specific IP's that are ok to log in from. Try
"man securetty" Example move is:

    cd /etc
    mv securetty securetty_dist

...note that the idea here is not to allow anyone to get into your
system from outside your LAN (or maybe even ON your LAN) as "root".
Doing this rename allows you in, but if you're widely connected, it
allows others in as well. Packet sniffers can obtain your password and
then others will on your system like flies on Windows.

1. Can't access my box via telnet...

1) I deleted the contents of the /tmp ... /var/tmp ... and /usr/temp...
        ( Then it would not allow anyone in but root )
2) I tried to install sudo and it gave me errors..so I deleted the SMCsudo
directory because it wouldn't let me
re-install it...
3) I installed TCP wrappers yesterday and set them to launch at rc3..(  I
put the sh in the rc3.d )

Now after I rebooted I can not access the box via telnet and also could not
ping it... Any ideas??/
