If the IP address is set as 0.0.0.0, then the access is possible from
anywhere in the network.

tftp
The command configures the TFTP server used for the firmware
upgrade. Three options are possible:
¡
tftp on
- enables the TFTP server
¡
tftp off
- disables the TFTP server
¡
tftp host <IP address>
- if the server is enabled, the access to
it may be limited to a certain IP address. If this address is set to
0.0.0.0, then the access isn’t limited.
4.3.32.
timeout
The command sets the inactivity time (in seconds), after which
the telnet connection is closed. It has following syntax:
timeout <during the session> [<during logging in>]
The first parameter is used after the logging in and the second
one (optional) during the log-in. Entering “0” disables the timer.
These settings are also applied to the serial console if its access is
password protected (using the „console passwd on” command).
4.3.33.
uptime, w
Shows the time elapsed since the modem booting and the current
processor temperature.
4.3.34.
user
The “user” command is used to manage users having access to
the modem. The modem may work in two different modes:
¡
single user
- only the password is necessary to access the
modem. The user that logs in has the full access to the device.
¡
multiple users
- allows creating many users with different
names, passwords and access levels
The “user” command has following syntax:
¡
user list
- shows the user list
¡
user add <name> -
adds a new user
¡
user del <name> -
removes an user
¡
user passwd <name> <password>
- changes the user’s
password
¡
user level <name> <access level>
- changes the user’s
access level. The <access level> parameter may be one of:
§
admin
- full access to the device
§
read-only
- permits only reading of the configuration and the
statistics
¡
user mode { single | multi }
- selects the working mode - to
either single or multi-user
4.3.35.
ver
Displays current firmware version.
4.3.36.
wake
The „wake” command is used to power-on a LAN station (e.g. a
PC) using „wake-on-LAN” functionality. The required parameter is
station's MAC address:
wake 00:01:c0:3c:14:50:46
An optional
„-b” parameter may be added before MAC address to
send the wake-up packet as a broadcast.
4.3.37.
watchdog
The “watchdog” command gives additional control over the
modem’s unpredicted behavior (i.e. a misconfiguration disabling further
communication with the modem). The modem uses the “ping” command
to check the availability of certain IP addresses and reboots, if one of
them doesn’t answer.
The command has following syntax:
¡
watchdog on
- enables the watchdog
¡
watchdog off
- disables the watchdog
¡
watchdog <interval> <amount> <wait> <IP address>
[<additional IP address> ]
- configures the watchdog. After
<interval>
seconds the modem sends
<amount>
of pings to
the
<IP address>
(and the
<additional IP address>
if set)
waiting
<wait>
seconds after each of them. If there is no answer
for any of the pings sent to the first address or for any of the pings
