System Administration 3-9
Providing TFTP Access Trivial File Transfer Protocol (TFTP) provides a simple way to transfer files from one
machine to another. The 3Com HomeConnect ADSL Modem Ethernet has a TFTP
server that allows you to copy files to or from the unit. All you have to do is set up
TFTP access on the 3Com HomeConnect ADSL Modem Ethernet and run a TFTP
client program on a workstation.
You can configure the 3Com HomeConnect ADSL Modem Ethernet to provide
access to all TFTP clients or you can specify the IP addresses of the TFTP clients for
restricted access.
■
To view the current TFTP client access list, use the command:
list tftp clients
■
To add a TFTP client to the list, use the command:
add tftp client <host name or IP address or 0.0.0.0>
Provide either the host name or the IP address of the workstation running the TFTP
client. An address of 0.0.0.0 allows all TFTP clients unrestricted access.
■
To remove a TFTP client from the list, use the command:
delete tftp client <host name or IP address or 0.0.0.0>
Setting Password
Protection
The 3Com HomeConnect ADSL Modem Ethernet provides the capability to
password-protect access to the CLI. When the password protection feature is
enabled, a user connecting to the CLI via the serial console port will be prompted
for the CLI password.
After the correct password is entered, all CLI commands are accessible by the user.
The user can ’exit’ from the CLI to disable further access or can configure an idle
timeout period. If no commands are executed by the CLI for a period longer than
the idle timeout period, the user will automatically be logged out of the console.
The password will have to be re-entered in order to access the CLI again.
CLI password protection is disabled by default.
Password protection can be configured by the QuickSetup program or by using
CLI commands.
■
To enable or disable CLI password protection, use the commands:
set command login_required yes or
set command login_required no
■
To configure the login password, use the command:
set command password < password>
■
where <password> is an alphanumeric string of 1 to 8 characters. The default
password is "password."
Be sure to save your configuration after entering a new password.
■
After logging in to the CLI, you can exit the CLI with the command:
exit cli
■
To set the idle timeout period, use the command:
set command idle_timeout <timeout>
■
where <timeout> specifies the idle timeout period in minutes.
By default, there is no idle timeout period.
