    In the Services panel located in Start>Settings>Control Panel>Administrative Tools>Services

    On linux, edit f you want to disable Telnet then edit the file /etc/xinetd.d/telnet and set the disable parameter to "yes".

    # default: on
    # description: The telnet server serves telnet sessions; it uses \
    # unencrypted username/password pairs for authentication.
    service telnet
           flags          = REUSE
           socket_type    = stream
           wait           = no
           user           = root
           server         = /usr/sbin/in.telnetd
           log_on_failure += USERID
           disable        = yes


    You'll then have to restart xinetd for the new settings to take effect.

     [root@bigboy tmp]# /etc/init.d/xinetd restart
