VIOLA SMSCONFIG VERSION 1.3

The smsconfig is meant for "emergency usage" to monitor and control the Arctic devices on the field. Such a situation would be e.g. when a configuration error prevents device GPRS/VPN access and dial-in access is not possible.

NOTE: USING GSM DATA DIAL-IN FOR DEVICE CONFIGURATION IS PREFERRED METHOD OVER SMSCONFIG. SMSCONFIG SHOULD ONLY BE USED AT "EMERGENCY SITUATIONS".

SETTINGS

The settings are done by using WEB configuration.

Enabled {yes | no}-defines whether the smsconfig is enabled or disabled

Get command access {disabled | everywhere | defined phone}-defines are the "get" smsconfig commands accepted. Disabled: Disables the "get" commands. Everywhere: Allows "get" commands from every phone. Defined phone: Requires the command to arrive from define phone number.

Get allowed phone [complete phone number]-if the "Get command access" parameter has value "defined phone" then the "get" commands are only accepted from that phone. The phone numbers are compared exactly so the number should have country code prefix (e.g. +358 for Finland) defined.

Get require password {yes | no}-additional to other "get" settings above, the password can be used to limit access to "get" commands. The password is same as Arctic's login password.

Set command access {disabled | everywhere | defined phone}-defines are the "set" smsconfig commands accepted. Disabled: Disables the "set" commands. Everywhere: Allows "set" commands from every phone. Defined phone: Requires the command to arrive from the predefined phone number.

Set allowed phone [complete phone number]-if the "Set command access" parameter has value "defined phone" then the "set" commands are only accepted from that phone. The phone numbers are compared exactly so the number should have country code prefix (e.g.+358 for Finland) defined.

Set require password {yes | no}-additional to other "set” settings above the password can be used to limit access to "set" commands. The password is same as Arctic's login password.

Set allow execute commands {yes | no}-additional to other "set” settings above this parameter can be used to limit access to "execute" commands like executing potentially dangerous user defined commands.

Reply error to unknown commands {yes | no}-defines are unknown SMS commands replied with error SMS or discarded silently.

Reply error to unauthorized commands {yes | no}-defines are unauthorized SMS commands (like having invalid password) replied with error SMS or discarded silently.

COMMAND SYNTAX

The smsconfig has two main types of commands, "set" and "get". The "set" commands are divided to "normal" and "execute" commands.

Examples:get hostnameset hostname MyArcticset execute reply setio 1 0All commands must be given by using small caps. The command parameters caps are not limited (e.g. "set gprs user SomeUser" is allowed).

If the password is required then it must be given before the commands and delimited with '#' character.

Example:mypass#get hostnameMaximum SMS message length is 160 characters. Commands can be concatenated to single SMS message by separating the commands with ';' character. The SMS command length must not exceed160 characters.

Example:mypass#set hostname MyArctic;set gprs apn INTERNET;set commit;get gprs statusIf the command has multiple parameters the parameters must be separated by comma "," character. Not all commands require every parameter. If the parameter is empty it's not altered. If there are less than maximum amount of parameters given, the parameters are processed in hard-coded order.

Examples:"set gprs settings" allows defining the:enabled,usepin,pin,apn,username,password,idle,defaultroute in single

message.

Giving values for all of the parameters:mypass#set gprs settings 1,1,1122,INTERNET,user,pass,1800,0Altering the value of "enabled" status only:mypass#set gprs settings 1ormypass#set gprs settings 1,,,,,,Altering the values of "enabled", "apn", "idle" and "defaultroute" only:mypass#set gprs settings 1,,,INTERNET,,,1800,0Altering the value of defaultroute only:mypass#set gprs settings ,,,,,,0

RETURN MESSAGES

The returned SMS messages contain the original command and response delimited by ':' character. With "get" commands the return message can be either the requested value or "error" message. With "set" commands the return message can be either "ok" message or "error" message.

Example of successful "get" response:get gprs apn:INTERNET

Example of "error" response:get gprs phonenumber:error (unknown function)

Example of successful "set" response:set gprs pin 1234:ok

EXAMPLES

The following examples present strategies for handling different problems.

PROBLEM 1The SMS commands are not working.

Solution:Check that you have SIM card with correct PIN installed to Arctic. This information is available on WEB UI Tools->Modeminfo. After that check from Network->SMS Config that the SMS Configuration is enabled and the set/get access are correct. Alter the settings if required, apply settings and reboot. Now send SMS command to Arctic and follow the system log file on Tools->Recent events to see are the commands processed.

PROBLEM 2The installation location is powered only occasionally and I need to known when Arctic is up in order to alter the configuration.

Solution:-send command "set echo im up now" to Arctic. When it is up it will reply to you with "I'm up now" SMS message. Then make dial-in to Arctic to configure.

PROBLEM 3Arctic on the field is totally unconfigured/I don't know the configuration. I need to configure it.

Solution A:-make dial-in connection to Arctic GSM number and configure it.-if dial-in is not successful send command "get dialin status" to see if someone is already using the dial-in (line busy) or if the dial-in is disabled.-if someone is using the dial-in send command "set dialin restart" in order to drop the user from line. After that try dial-in again.

-if the dial-in is disabled enable it, commit and reboot with "set dialin settings;set commit;set reboot" and try again-if dial-in is not working it probably means the SIM card has not GSM data call enabled, the network does not support GSM data call or the network is busy. On that case move to solution B below.

Solution B:-Set up M2M Gateway to public IP address that Arctic can form the SSH-VPN connection to it-enable FTP server and WEB server on M2M GW and make required holes to firewall-define new peer to M2M GW SSH-VPN with appropriate hostname-configure Arctic to default settings with: "set default"-wait for response-configure Arctic hostname and GPRS with SMS:"set hostname myarctic;set gprs settings 1,<pincode>,<apn>,<user>,<pass>,1800,0"-wait until Arctic replies to both commands with OK-configure Arctic SSH-VPN with:"set sshvpn settings 1,gprs,<your_m2mgw_ip>,22,0,0,,0;set commit;set reboot"-wait few minutes until Arctic is up again-change the keys with"set sshvpn fetchkey ,,;set sshvpn sendkey ,,<user>,<pass>,,"-insert the file to "known hosts" on M2M GW-wait until Arctic forms the SSH-VPN connection to M2M GW-now it's possible to Access Arctic by using VPN connection

Solution C:-Set up M2M Gateway to public IP address that Arctic can form the SSH-VPN connection to it-enable FTP server and WEB server on M2M GW and make required holes to firewall-define new peer to M2M GW SSH-VPN with appropriate hostname-form a script to be executed on Arctic to configure it-store the script to M2M GW WEB server-configure Arctic GPRS with:"set hostname <your_hostname>;set gprs settings 1,<pincode>,<apn>,<user>,<pass>,1800,0;set commit;set restart gprs"-wait few minutes until GPRS is up-download and execute the script on Arctic by"set execute download <your_script>,<your_m2mg_ip>,gprs;set commit;set reboot"

HINTS

When constructing the update scripts executed on Arctic one can use the shell-tools sendftp and wget to send and receive files. Also shell-tool sendsms is available for sending SMS. Set the hostname with SMS before running the update script.

In that case you can identify the required files on server by using hostname as a key to correct folder. The hostname for script is available with command `cat /proc/config/hostname`.
