Note : l'adresse IP 192.168.0.17 est celle du deuxième PC que j'utilise pour communiquer avec le PC ayant le problème.
Merci pour tes suggestions. Voici dans l'ordre les commandes que j'ai exécutées:
piantino@Piantino-25:~> sudo systemctl start firewalld.service
[sudo] Mot de passe de root :
Job for firewalld.service failed because a fatal signal was delivered causing the control process to dump core.
See "systemctl status firewalld.service" and "journalctl -xe" for details.
