Analisando a conexão entre nós no librerouterOS/libremesh

Nesse tutorial vamos aprender como analisar a conexão entre os nós em uma rede mesh baseada em Libremesh

1- Acesse o seu roteador por ssh:

ssh root@thisnode.info

2- Identifique a(s) interfaces mesh do seu dispositivo:

root@gateway:~# iwinfo
wlan0-mesh ESSID: "LiMe"
          Access Point: A8:40:41:1C:85:A0
          Mode: Mesh Point  Channel: 11 (2.462 GHz)
          Tx-Power: 26 dBm  Link Quality: 42/70
          Signal: -68 dBm  Noise: -83 dBm
          Bit Rate: 25.3 MBit/s
          Encryption: unknown
          Type: nl80211  HW Mode(s): 802.11bgn
          Hardware: unknown [Generic MAC80211]
          TX power offset: unknown
          Frequency offset: unknown
          Supports VAPs: yes  PHY name: phy0

wlan1-mesh ESSID: "LiMe"
          Access Point: A8:40:41:1C:83:F2
          Mode: Mesh Point  Channel: 48 (5.240 GHz)
          Tx-Power: 23 dBm  Link Quality: 27/70
          Signal: -84 dBm  Noise: -94 dBm
          Bit Rate: 65.8 MBit/s
          Encryption: unknown
          Type: nl80211  HW Mode(s): 802.11an
          Hardware: 168C:0033 168C:0205 [Generic MAC80211]
          TX power offset: unknown
          Frequency offset: unknown
          Supports VAPs: yes  PHY name: phy1

wlan2-mesh ESSID: "LiMe"
          Access Point: A8:40:41:1C:83:DB
          Mode: Mesh Point  Channel: 157 (5.785 GHz)
          Tx-Power: 27 dBm  Link Quality: 27/70
          Signal: -83 dBm  Noise: -92 dBm
          Bit Rate: 40.5 MBit/s
          Encryption: unknown
          Type: nl80211  HW Mode(s): 802.11an
          Hardware: 168C:0033 168C:0205 [Generic MAC80211]
          TX power offset: unknown
          Frequency offset: unknown
          Supports VAPs: yes  PHY name: phy2

3- Nesse caso temos duas interfaces responsáveis por fazer conexões na malha, wlan1-mesh e wlan2-mesh. Para ver as conexões que wlan1-mesh está fazendo podemos usar o comando:

4- N
