BASH – Connessione a Internet vista da Ubuntu
BASH – Connessione a Internet vista da Ubuntu – Aggiornamento anno 2024.
ATTENZIONE: Le prove sono state effettuate su un PC dotato di hardware in grado di connettersi ad internet sia tramite rete Ethernet, sia tramite WiFi USB, sia tramite WiFi integrato. I relativi output rilevano 2 periferiche WiFi USB in quanto -come dimostra l’output del comando [lsusb -vt]- la periferica WiFi USB integrata è connessa alla scheda madre tramite porta USB interna.
Il comando [dmesg] può essere impartito senza i pribilegi di amministratore solo se prima di impartirlo è stato impartito il comando
sudo sysctl -w kernel.dmesg_restrict=0 # UBUNTU: sudo dmesg DIVENTA dmesg
Quest’ultimo comando diviene efficace quando viene impartito e perde di efficacia allo spegnimento del computer.
