SSH/Telnet into Nokia G-2425G-A

2024-01-26

Device Infromation:

Device Name G-2425G-A
Vendor Nokia
Boot Version U-Boot Dec-31-2016--12:00:00
Router IP https://192.168.1.254
Chipset MTK7528

Default login for SSH, Telnet CLI, and Web GUI AdminGPON / ALC#FGU. However this can be changed by ISP by using TR069 after connecting the fiber cable.

There is also another user userAdmin / userAdmin.

Steps#

Reset the router so that it is possible to use the AdminGPON user. Another way is to extract the configuration after ISP has setup the modem router using TR-069. (contact me for further info – see secure notes on phone)
Extract the cfg file using nokia-router-cfg-tool.py
Enable TelnetSSHAccount. in the extracted XML file using the script above. Set username as ONTUSER and password as OYdLWUVDdKQTPaCIeTqniA== which equates to admin. If using another username, root access might not be possible.

<TelnetSshAccount. n="TelnetSshAccount" t="staticObject">
<Enable rw="RW" t="boolean" v="true"></Enable>
<UserName ml="64" rw="RW" t="string" v="ONTUSER"></UserName>
<Password ml="64" rw="RW" t="string" v="2NtCuV9+tykYlr4EmoJFxg==" ealgo="ab"></Password>
</TelnetSshAccount.>

Set LimitAccount_ONTUSER to false. Further, ONTLOCK (search the XML file) might also be needed to be set to false

<LimitAccount_ONTUSER rw="RW" t="boolean" v="false"></LimitAccount_ONTUSER>
<X_ASB_COM_ONTLOCK t="boolean" v="false" dv="false" rw="RW"></X_ASB_COM_ONTLOCK>

Repack the xml file using nokia-router-cfg-tool.py
Upload the new cfg file into the router. You might want to use a LAN connection for this, but it has been working fine over WLAN for me.

Notes#

After logging to the router portal, greyed-out (disabled) settings can be changed using the inspect element and removing the disabled prop from html.
