 Unix Tip #4327- January 15, 2025
 
LOCK DOWN TELNET OR FTP  
  
When inbound access isn't required into  
a system deny users Telnet or FTP access  
do the following:  
  
vi /etc/inetd.conf  
  
Comment the line starts with Telnet or  
FTP.  Save the file and exit.  
  
Stop and start the inetd daemon now by  
following commands:  
  
/etc/rc.d/init.d/inet stop  
  
/etc/rc.d/init.d/inet start  
  
(Your flavor may be /etc/init.d)
