+persist across a reboot.
+If prompted by sudo, use student as the password.
+From workstation, test access to the default web server at http://
+serverb.lab.example.com and to the virtual host at http://
+serverb.lab.example.com:1001.

+4. From workstation, test access to the default web server at http://
+serverb.lab.example.com and to the virtual host at http://
