sec
Syntax: sec [port#] [options]
Description: This command changes the permission lists for each port. Each port has an IP
address white list. The white list contains the IP addresses checked each time a
serial port is opened through the network. If the client’s IP is not in the list the
client will be denied access to that serial port. If the list is empty then any client
may open the port. If there is a lockout associated with the list then no client can
access the list. The sec command allows you to display and edit these IP security
white lists. The permission level is used to allow access to groups of commands.
Options: port#
This specifies the port number. This number can be any valid port number
starting at 1 to the number of ports available on the particular Blue Heat/Net
unit.
list
This displays the current white list for the specified port. Remember, if the list
is empty, any client (any IP) can access the port. There is no sub option for this
command.
clear
This removes all IP addresses from a list, thus allowing any client to access the
port. This command also clears the lockout if it exits. There is no sub option for
this command.
rm
This command is used in conjunction with the list command. The user typically
examines the IP white list and makes note of which entry needs to be removed.
You must note the record number that appears to the left of the IP. Use this
record number as a sub option to the sec/rm command, in order to remove a
desired IP.
add
This appends new IPs to a given list. The sub option for the sec/add command is
a valid IP in dot-number notation. You may want to execute the list command to
confirm that an IP was successfully added.
lockout
This list is used to deny access to the specified serial port. There is no sub
option for this command. The lockout can be eliminated with a clear command.
Examples: sec 1 list Display the IP white list for port number 1.
sec 5 clear Clear the IP white list for port number 5.
sec 3 add 210.98.82.99 Add IP 210.98.82.99 to the white list for port number 3.
sec 3 rm 1 Remove the 1
st
entry in the white list for port number 3.
