DuraMAR 2150 – User’s Manual
Limiting remote access to the system
Access to the system by connecting through the
gprs0
interface can be restricted to a list of specific IP
addresses. There are no limits to the number of IP addresses in the list.
By default there is no access restriction. By issuing one or more
set admin-ip
ip-address
commands the
user can restrict the access to only the given IP addresses.
The
no-form
of the command removes the permission. If the list is empty, the access will be automatically
granted from any IP address.
Here is an example that allows access from just two IP address:
!
set admin-ip 217.22.11.23
set admin-ip 217.22.11.24
!
These restrictions apply to any kind of IP traffic coming from an IP address that is not included in the list,
thus also SSH, SNMP and ICMP packets will be rejected.
Rebooting the system
An immediate reboot of the ECC system can be performed by issuing the
reboot
command. Please note
that this command will reboot ECC only, while CISCO 3200 ISR subsystem will not be affected.
Setting controller time and date
The user can setup the controller time and date using the
set time
configuration command.
There is no internal battery for maintaining the system’s clock so, if the device is powered off for a couple of
hours or more, the time will be lost.
If you need or want to maintain a precise system time you can keep the system clock in sync with up to three
external NTP (Network Time Protocol) servers using the
set ntp
configuration command. Please note that
when the system operates in Bridge Mode, one or more static routes need to be defined for this feature to
work (see further for details)
The complete list of commands available for managing system time:
show time
Displays the current time and date
Sets the current time and date values
set time hh:mm[:ss] mm/dd/yyyy
Defines up to three NTP servers
set ntp <ip-address> [ip-address ip
address]
Setting the time zone
The internal clock is typically maintained in UTC coordinates. You can define the time zone in which the
system is used using the
set tz
configuration command.
The time zone is expressed defining the name of a geographical area (ie. Europe, Asia,..) followed by the
name of a city in that area (ie. Rome, Singapore,…). A question mark (?) can be used in place of the zone or
city names, to obtain a list of these fields.
The syntax of this command is:
set tz <area name> <city name>
25
