According to the method provided by the user, first use the Rpm-qa telnet query to install the Telnet Service Pack, the RHEL5 system is installed, and then modify the Telnet service profile, there are some xinetd-bound services under/etc/xinetd.d/, You can find ekrb5_telnet and krb5_telnet, both of which are configuration files for the Telnet service, which can only be used for ciphertext transmissions (authenticated using the Kerberos protocol), The latter can be used for both plaintext transmission (which is generally used for the transmission of plaintext) or ciphertext transfer. Using krb5_telnet instead of ekrb5_telnet, open krb5_telnet with vim, find the Disable line, and then modify Yes No, save, and then restart xinetd~~
