After fixing this problem in /etc/hosts: 192.168.0.127 raspberry8.alogt.com Raspberry8 192.168.0.128 raspberry8.alogt.com Raspberry9 After fixing the second line to 192.168.0.127 raspberry8.alogt.com Raspberry8 192.168.0.128 raspberry9.alogt.com Raspberry9 and adjusting the names in the respective /etc/rc.conf files, everything started to work. Before, I left then names as they have been but changed the IP addresses of the clients to run some tests. I do not know why is affected IPs above 120 but not the IPs from 116 to 120.
