AIX7-00-003081 - The tftp daemon must be disabled on AIX.

Information

The tftp service allows remote systems to download or upload files to the tftp server without any authentication. It is therefore a service that should not run, unless needed. One of the main reasons for requiring this service to be activated is if the host is a NIM master. However, the service can be enabled and then disabled once a NIM operation has completed, rather than left running permanently.

Solution

In "/etc/inetd.conf", comment out the "tftp" entry by running command:
# chsubserver -r inetd -C /etc/inetd.conf -d -v 'tftp' -p 'udp'

Restart inetd:
# refresh -s inetd
