ONFIGURING THE
RAS 1500
ROUTER
Using TFTP
TFTP (Trivial File Transfer Protocol) can be used to transfer files to and from
the system. Since this network service is enabled by default, set it up by
first configuring your computer as a TFTP client of the stack by entering
this command:
add TFTP client <hostname or IP address>
If you want to allow any system to TFTP into your system, set a TFTP client
to 000.000.000.000.
Next, from a machine that has access to the same network, use the
following TFTP commands to transfer the filter file to FLASH memory:
tftp <RAS 1500 IP address>
put <filename>
Use
list files
to verify the file was sent to RAS 1500.
If you want to obtain a file from another network host, add that host as a
TFTP client, and, from within the system, use Telnet to access that host
and use the following command to obtain the file:
get <filename>
Do not transfer binary files. Transferring binary files of any type will cause
unexpected results and may cause RAS 1500 to “hang.”
Using Rlogin and Telnet
You can connect to a specific host on the network using the
rlogin
or
telnet
commands. You must first have used the
add dns host
or
add dns server
commands for RAS 1500 to recognize an IP host
name. Both services are enabled at startup.
Rlogin is not supported into RAS 1500. You can only use rlogin to
communicate out of RAS 1500.
Rlogin and Telnet use the following syntax:
rlogin <IP name or address>
login_name <name>
tcp_port <number>
or:
telnet <IP name or address>
