Perhaps you could start by telling us what OS you are discussing but then
again maybe the following will answer your question? The commonly used
access methods are often controlled by a daemon 'inetd' so chances are you
want to look at commenting out lines in /etc/inetd.conf, in particular lines
beginning with ftp, telnet, shell, login, exec. It should be noted that if
your system can simultaneously support IPv4 and IPv6 ( e.g. Solaris 8 )
there may be multiple instances for some services, obviously you should
comment out all instances of each service you wish to disable. Personally
speaking on one of our hosts we run with a completely empty inetd.conf and
since sshd is started independently of inetd it is unaffected. To get inetd
to reread the configuration file you must send it the hang-up signal which
can be achieved by finding the process id of the daemon and then issuing
'kill -HUP process_id'. You probably want to read the man pages for 'ps' on
your host to find out how to do this.
On Solaris and IRIX for instance you can issue the following commands
blink 52 > ps -ef | grep inetd
root 146 1 0 Jan 05 ? 0:32 /usr/sbin/inetd -s
kennys 2752 2705 0 09:53:25 pts/7 0:00 grep inetd
blink 53 > kill -HUP 146
On Solaris 7 and 8 you can do the same thing in a single step with
blink 54 > pkill -HUP inetd
On IRIX the equivalent is
sneeze 12 > killall -HUP inetd
