Problem Details

In case you have lost the password for an innovaphone device and there is no recent config backup available, you are still able to recover the device config.

There are two possible solutions, depending on given requirements:

• Update Server approach
• TFTP approach

The prefered approach is to use an Update Server. The last resort is to use TFTP mode to download the device config.

System Requirements

Update Server approach:

• Update Server URL need to be configured before you have lost the password

TFTP approach:

• appropriate boot code version need to be installed on device
• gwload.exe
• TFTP client

Update Server

If you know that there is an Update Server URL configured on the device and you have access to the web server with an update script on it, you can change the polled update script as follows to reset the admin password on the device.

# reset password
config change CMD0 /name mydevicehostname /log on /user admin,ip6000
config write
# encrypt it
config activate
# remove from visible config
config change CMD0 /name mydevicehostname /log on 
# done

In case one of ETH interfaces is configured as DHCP client, you can provide Update Server URL to device via DHCP.

TFTP

If the prefered usage of the Update Server approach is not possible you have to get the device configuration via TFTP as a last resort. Make sure you have read articles about Factory Reset and Gwload Utility, before you start to recover the device configuration via TFTP.

Set device to TFTP mode

Setting the device in TFTP mode is made by pressing reset button on gateway for ca. 1,5-2 sec (active LED must blink 3 times). Be careful cause if you press reset button too long, it will perform a factory reset, which means the config is lost.

Set IP adress of device with gwload

Once set to TFTP mode, the device is without IP address so you have to set it with gwload:

gwload /gwtype 6000 /i 192.168.0.1 /setip

Download config from device using TFTP-Client

Now you can use any TFTP client to download the config from device. There two different versions of boot code, so config file on device can be called c or config.

Open shell of your operating system and type:

tftp -i 192.168.0.1 GET config config.txt

or if you have device with older boot code version:

tftp -i 192.168.0.1 GET c config.txt

Now you'll have a file with config text repeated several times in it, so you have to search for latest config that was saved in this ring buffer.

This config can be changed to a known password ( e.g. config change CMD0 /user admin,ip6000 ). After sending this config to the device:

gwload /gwtype 6000 /i 192.168.0.1 /setip /cfg config.txt

the new config is effective. On the first start of the firmware the user/password definition is copied from the commandline to a crypted var.

This procedure keeps the configuration and the flashdir (ldap) directory because no long reset is done.

Known Problems

The config.txt file recovered with TFTP only includes the partial configuration (lines starting with config change). No vars, no FLASHDIR.
