Usage

Enable SSH and Telnet

1. Log in to the web interface (http://192.168.1.1, user 1234, password 1234).
2. Open the developer console of the browser and run the commands one by one: they enable SSH (port 22) and Telnet (port 23) for the user with uid 3.

$.xmo.getValuesTree("Device");
$.xmo.getValuesTree("Device/UserAccounts/Users");
$.xmo.getValuesTree("Device/UserAccounts/Users/User[@uid='3']");
$.xmo.getValuesTree("Device/UserAccounts/Users/User[@uid='3']/RemoteAccesses");
$.xmo.getValuesTree("Device/UserAccounts/Users/User[@uid='3']/RemoteAccesses/RemoteAccess[@uid='3']/Enabled");
$.xmo.getValuesTree("Device/UserAccounts/Users/User[@uid='3']/RemoteAccesses/RemoteAccess[@uid='4']/Enabled");
$.xmo.setValuesTree("ACCESS_ENABLE_ALL", "Device/UserAccounts/Users/User[@uid='3']/RemoteAccesses/RemoteAccess[@uid='3']/LANRestriction");
$.xmo.setValuesTree("ACCESS_ENABLE_ALL", "Device/UserAccounts/Users/User[@uid='3']/RemoteAccesses/RemoteAccess[@uid='4']/LANRestriction");
$.xmo.setValuesTree(22, "Device/UserAccounts/Users/User[@uid='3']/RemoteAccesses/RemoteAccess[@uid='3']/Port");
$.xmo.setValuesTree(23, "Device/UserAccounts/Users/User[@uid='3']/RemoteAccesses/RemoteAccess[@uid='4']/Port");
$.xmo.setValuesTree(true, "Device/UserAccounts/Users/User[@uid='3']/RemoteAccesses/RemoteAccess[@uid='3']/Enabled");
$.xmo.setValuesTree(true, "Device/UserAccounts/Users/User[@uid='3']/RemoteAccesses/RemoteAccess[@uid='4']/Enabled");

3. Reboot the modem from the maintenance page.
4. Connect with ssh 1234@192.168.1.1 and run su (password root).

Note

If a command returns null or the SSH connection times out, retry with the fiber disconnected.

GPON/OMCI settings

Getting ONU GPON PLOAM password

cat /opt/filesystem2/data/optical_conf.txt

Alternatively, copy the configuration on a USB stick and search the RegId tag (the PLOAM password, in hex) in cfg.xml:

cp /tmp/cfg.xml /mnt/sda1

The mount point can also be /mnt/sda. The same file also contains the SIP credentials of the VoIP line. The PLOAM password can be converted from hex to ASCII with the ASCII/HEX converter.
