Lista de comandos para routers Technicolor

Aqui temos uma lista de comandos telnet para utilização em routers technicolor que a MEO e a Vodafone utilizam.

(Os comandos foram achados na internet e a GCT não se responsabiliza por problemas causados pelo o utilizador.)

Deve-se entrar no cmd e colocar  telnet 192.168.1.254     (192.168.1.254 é o endereço do vosso router).

De seguida a linha de comandos vai pedir o utilizador e a password, após a autenticação os comandos podem ser usados.

Alguns dos comandos necessitam de acesso root.

Note (1) :
The “intf=Internet” part of the above commands may need to be changed depending on the routers firmware.
ie “intf=Internet” should be correct for standard firmware.
O2 supplied routers may need “intf=Internet” replacing with :-
For O2 supplied routers on a LLU connections replace with “intf=O2_ADSL2plus” or in some cases “intf=RoutedEthoA”
For O2 supplied routers on the Access service replace with “intf=O2_ADSL”
Hint – You can check which one to use for the WAN interface by looking at the results from the “dns server route list” command.
See the screen capture below, in this case it’s “intf=O2_ADSL2plus”.

Note (2)
To close the telnet session type — exit — press “enter”

  • Bom dia!
    Agradeço a listagem de comandos! Mas..a maioria não funciona!:

    Este, por exemplo:
    {Administrator}=>script add name=useroot command=”user add name=Administrator password=xxxxxxxxxxxx role=root”
    Command not allowed.
    {Administrator}=>script add name=useroot command=”user add name=Administrator”
    Command not allowed

    Acho que deveriam testar os comandos antes de os publicar…penso eu!
    Como contornar esta situação?
    É que, na maioria, dá sempre: Command not allowed

    • Bom dia,
      como foi indicado, para alguns comandos, é necessário acesso root, aqui temos um router desbloqueado tg784n v3 e quase todos funcionaram. No router tg789vac v2 é normal a maioria não funcionar porque não existe acesso root. Quando existe a mensagem “Command not allowed” significa que o utilizador não tem as permissões necessárias para fazer a alteração.
      Alguns dos routers MEO já tem root e pode ser consultado nesta página: http://gigacom.servehttp.com/gct/index.php/2016/07/09/root-tg784n-v3-meo/
      Para a Vodafone o utilizador deverá ser : Administrator ou Administrador (sem password), onde não é necessário criar acesso root.
      Alguns dos comandos têm o seguinte: “intf=Internet” que pode mudar para intf=InternetGPON, intf=InternetADSL, ou outra designação.
