Re: TFTP service
If you want to disable particular service not to listen, disable the service on /etc/services file

Re: TFTP service
tftpd is started usually from inted. Did you disabled the corresponding line from inted.conf and re-configured inetd (inetd -c)?
For the existing connections you must kill the running daemon (tftpd)

Please stop offering this defective advice.
Leave "/etc/services" in peace.

HOW? Rather than tell us what you hope that
you did, it might help to tell us what you
actually did. As usual, showing actual
commands with their actual output can be more
helpful than vague descriptions and interpretations.

Commenting out any line from /etc/services it is a bad habit.
Also, commenting out the very same line could or could not disable the service from starting.
/etc/services it is only a mapper of ports and protocols into service names.

If you have seen my question thoroughly u should have understood.
i have mentioned.
"i have added entry tftp deny in /var/adm/inetd.sec"
And my question is once we disabled tftp service after running #netstat -a |grep -i tftp
i am getting output "udp 0 0 *.tftp *.*"
what can be done to disable listining of tftp service?
Thanks to confirm....

Solution"i have added entry tftp deny in /var/adm/inetd.sec"
This does not mean that you actually disabled the tftpd daemon.
You only stopped new connections through inetd on tftp server. But if your tftpd server is still running or it is not even started from inetd (yes, tftpd can be started also outside of inetd as a stand alone service), your actions would have no effect on new connections
To actually disable the service you must comment the corresponding line from /etc/inetd.conf (put a # in fromt of it) if tftpd is started from inetd.
Best regards,
Horia.

Hence my confusion, and request for accurate
information.

Kicking inetd after editing its configuration
file can be helpful, too.
man inetd
Look for "-c".
