Cable Modem Factory Reset

Here is what I am trying do:
I need to be able to factory reset Cable Modems through SNMP.
I need to do it so that web access username/password of the modem is reset to default.
I also need to reset all the settings.

I am working with Motorola, Arris, SMC and other manufacturer cable modems.
I have my own test head-end to be able to do this. So I have all access to settings, snmp etc.

Does anybody know how I can do this through SNMP or through some other access like telnet? The manual reset by pressing button wont work for me.

Please help. Desperate.

Motorola

on Motorola you can set the Username and Password for the Web-Access in the CM Config-File:

SnmpMibObject cmRegularUserName.0 String "admin";
SnmpMibObject cmRegularUserPassword.0 String "admin";
SnmpMibObject cmSuperUserName.0 String "root";
SnmpMibObject cmSuperUserPassword.0 String "root";

and reboot over snmp with:

snmpset -v 2c -c $COMMUNITY $IP .1.3.6.1.2.1.69.1.1.3.0 i 1

Arris

On arris modems, this is set in the cm config file, and cannot be changed by a factory reset - except for the gateways, but that only pertains to the user side entry for the gateway part of the modem. For arris, you set a DES encryption key for the PWoD in your cm config, and use arris's pwod tool to generate the daily password for access. (the tool will also give you the des encryption key to enter for whatever base password you use for the key)

What is the above for exactly?

Arris

In Arris, all access is granted by a password (password of the day) generated against the date and your DES encryption key, so it changes daily.
In the tool, you type in a seed (base password) that is 8 characters long, it will then generate you a DES key, that you add into your cm config.
SnmpMib = arrisCmDoc30AccessClientSeed.0 hexstr: 54.49.33.EF.84.B0.79.89
Then, when you want to access telnet or the advanced pages of the modem, it will ask for a password that is made by that key+todaysdate.
You *want* to put in your own key, because the default is well-known and makes the modem easily accessible. You can get a tool online to generate the password of the day based on the default des key. The key should be put in all your Arris config files.

There is a seperate but similar mib for their Docsis 2.0 modems.
SnmpMib = arrisCmDevHttpClientSeed.0 hexstr: 54.49.33.EF.84.B0.79.89

If you are using a common config, then put them both in it.
You can get the tool from Arris, it comes with PacketAce - their modem/mta config file editor.
