Hello,
I am doing the Troubleshooting in paradise challenge in the foundations of cybersecurity course I manged to fix linux-A and linux-B so they can both ping to 8.8.8.8 and google.com linux-A can ping to Linux-B and Browser-B but with 0% packet loss. I am trying to set up and smb server called FILESERVER to troubleshoot smb share connectivity using dns however linux-A still doesn’t recognize the server… I appreciate the help.
The point of the lab is to fix issues on Linux-A, Linux-B and Browser-B as they have intentionally broken network configurations. There is also a DNS issue on the DNS server to fix (an A record is missing). SMB is not part of the challenge 
Is this something you are trying to fix above and beyond the challenge requirements?
In the Network Troubleshooting Basics lab, Linux-B (10.10.10.10) is configured to reach FILESERVER by adding a HOSTS file entry for FILESERVER. The 10.10.10.0/24 network does not use 192.168.1.5 for DNS.
I’m trying to ping the FILESERVER on the network troubleshooting basics. Anyone know what to do?
