How do I disable FTP and/or Telnet on an NAC appliance?

Answer

Product and Software: This article applies to all ECS product and software versions.

Requirements

  • SSH software (for example: PuTTY)

  • Familiarity with vi editor

Procedure

1) SSH into the NAC appliance.

2) Back up the 'inetd.conf' file:

cp /etc/inetd.conf /etc/inetd.conf.bak

3) Edit the 'inetd.conf' file:

vi /etc/inetd.conf

4) Comment out the following lines by typing a # in front of them.

For FTP:

ftp stream tcp nowait root /usr/sbin/tcpd in.ftpd

For Telnet:

telnet stream tcp nowait root /usr/sbin/tcpd in.telnetd

5) Save the file

:wq

6) Restart 'inetd' by issuing an HUP (hang up) kill:

kill -HUP inetd 
or
kill -HUP <inetd process id> (such as, kill -HUP 1754)

7) Test to ensure you cannot Telnet/FTP into the NAC appliance.
