-====== Ubuntu - Legacy Communication Services ======
-A large number of legacy Unix programs do not provide essential security during data transmission. These include FTP, Telnet, rlogin, and rsh. No matter whether you’re securing your Linux server or personal system, stop using these services for good.
-You can use other alternatives for this type of data transfer tasks. For example, services like OpenSSH, SFTP, or FTPS makes sure that data transmission happens over a secure channel.
-Some of them employ SSL or TLS encryptions to harden your data communication.
-You may use the below commands to remove legacy services like NIS, telnet, and rsh from your system.
-<code bash>
-# yum erase xinetd ypserv tftp-server telnet-server rsh-server
-# apt-get --purge remove xinetd nis yp-tools tftpd atftpd tftpd-hpa telnetd rsh-server rsh-redone-server
