The question was:
I would like to disable FTP service for incoming requests on a Tru64 box. Is
it possible to do that temporally without to rebuild kernel or stuff like
that?
I know I have to modify /etc/services file to disable outgoing FTP sessions
but how to disable incoming? Can I disable the service for particular user?
The answers :
1.
Comment out the ftp entry in /etc/inetd.conf and send a HUP signal to the
inetd.
For example, kill -HUP 1234

2.
Comment out the line in /etc/inetd.conf which starts ftpd. Then " kill -1 1"
and you are done.

In the file /etc/inetd.conf comment out the following line:
ftp stream tcp nowait root /usr/sbin/ftpd ftpd
Then restart inetd. This will stop all incoming FTPs.

if you want to disable ftp for a particular user, theres a file in /etc
called ftpusers
simply add a user to each line to deny ftp service

/etc/ftpusers will disable for listed users.

comment out with a # the ftp entry in /etc/inetd.conf
you will have to HUP inetd ( kill -HUP <pid of inets>) or reboot.
look for tcp wrapper to control incoming access.

Go into your /etc/inetd.conf file and comment (#) out your ftp line. Then
kill -HUP your inetd service.

Do a cut -f1 -d: /etc/passwd (which cuts the login name from the password
file) >/etc/ftpusers . This file will disallow all people who have access
to your system with telnet or rlogin. (I would recommend removing root from
this list.) You can add logins to this list as necessary. (That where the
particular users comes in.) Check the man page for more info.

Deleting or comments out ftp in /etc/inetd.conf and /etc/services will stop
incoming requests.
I don't think that has any effect on outgoing requests (except you could no
longer use "ftp"
as an alias for port 21 in telnet commands if you do that).

Comment the ftp line out of your /etc/inetd.conf file will disable all
incoming FTP requests.
If you don't want to disable it for all users, you'll find downloading and
installing tcpwrappers to handle
your incoming requests very helpful. It allows you to specify users and/or
groups of users in
.allow and .deny files.

You rem out the ftp line in /etc/inetd.conf. Then HUP the inet daemon. This
will keep anyone from logging in using ftp. You can also use TCP Wrappers to
allow/deny by ip address.

comment out the line for ftpd in /etc/inetd.conf and the send a HUP signal
to the inetd process.
