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
