Ubuntu-Server-Hardening

1. Avoid Using FTP, Telnet, And Rlogin / Rsh Services on Linux

Under most network configurations, user names, passwords, FTP / telnet / rsh commands and transferred files can be captured by anyone on the same network using a packet sniffer. The common solution to this problem is to use either OpenSSH , SFTP, or FTPS (FTP over SSL), which adds SSL or TLS encryption to FTP.

Type the following command to delete NIS, rsh and other outdated service:

sudo apt --purge remove xinetd nis yp-tools tftpd atftpd tftpd-hpa telnetd rsh-server rsh-redone-server
