| Description | ||||
| 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. | ||||
