How to Enable TELNET for root user in Linux.

Now before getting into the details of how to configure Red Hat Linux for root logins, keep in mind that this is VERY BAD security. Make sure that you NEVER configure your production servers for this type of login.

    Configure Telnet for root logins

    Simply edit the file /etc/securetty and add the following to the end of the file:

    pts/0
    pts/1
    pts/2
    pts/3
    pts/4
    pts/5
    pts/6
    pts/7
    pts/8
    pts/9

    This will allow up to 10 telnet sessions to the server as root.

    Configure FTP for root logins

    Edit the files /etc/vsftpd.ftpusers and /etc/vsftpd.user_list and remove the 'root' line from each file.

This is strongly discouraged as you will end up sending root password in clear over the network.

The alternative approach is to telnet as a normal user then use "su" to get to root.

However even that is frowned on and ssh should be used instead of telnet.
