On the Mac mini normally en0 is the built-in Ethernet and en1 is the AirPort. Even on the Mac mini you are using the built-in Ethernet and built-in AirPort (WiFi) still count as two interfaces. Some models of Mac such as the Mac Pro and XServe have two Ethernet interfaces. The error you listed of "Jul 6 11:47:43 localhost configd: bootp_session_transmit: bpf_write(en1) failed: Network is down (50)" might be suggesting you have enabled the NetBoot service on a network interface which is not in use. The first thing to do is to get things so the NetBoot image does show up in Startup Disks, then worry later about actually trying to NetBoot. what Interfaces have you enabled it to serve on, what archictectures are supported, have you configured any restrictions as to models that can connect, have you configured a filter for MAC addresses, etc.? Can you however provide more details as to your NetBoot configuration, e.g. The NetBoot service does not need to run on a server also running DHCP so you are ok on that front, you will only need AFP if you are going to use diskless NetBoot. It appears that the remote host is not getting a proper DHCP address and therefore cannot see the netboot server.?Īny suggestions or help would be greatly appreciated!

You may be able to start your Mac with Apple Diagnostics, even if it doesn’t start using macOS. What am I missing? The only thing I have been able to find so far are these entires in the NetBoot log within Server Admin: Apple Diagnostics is a tool you can use to diagnose problems with your computer’s internal hardware, such as the logic board, memory, and wireless components. The permissions are set so that everyone can read the image files. If I turn AFP on, I can connect to it that way and view the image files, etc. When going into System Preferences > Startup Disk, it does not see the AST server. I get the flashing globe for about 20 - 30 seconds and then the system boots normally into the OS. However, when I plug in a remote host on the same network segment (same subnet), it will not netboot. I also registered my Gateway Manager with my Apple ID and ASP location, etc. I gave the server a static IP and reserved it in our DHCP server. I DO NOT have DHCP turned on on this machine, namely because:Ī.) We have a district DHCP server supplying IPs to all our machines, andī.) The instructions from Apple actually say to avoid running any services on the AST Gateway machine besides NFS and NetBoot. In Server Admin, I turned on only NFS and NetBoot services (as per the instructions) and configured NetBoot to work via Ethernet with the AST image as the default. Installation was no problem and everything went smoothly. I have followed Apple's instructions on how to install/configure AST Diagnostic Gateway from the Service Source page to the T. Here are the specs of the Mini, if needed by anyone: NBI is not intended to replace histopathological sampling as a means of diagnosis.I recently set up a new Mac Mini as a stand-alone server for the Apple Service Toolkit Diagnostic Gateway. *Based on a weighted average, studies have shown that using NBI allows physicians to visualize lesion boundaries. Studies* have shown that NBI visualized 17% additional patients with Non-Muscle Invasive Bladder Cancer, 24% additional tumors and 28% additional Carcinoma In Situ (CIS). Blue and green light are strongly absorbed by hemoglobin and appear darker than normal tissue. Unlike white light, which uses all colors in the spectrum, NBI uses only blue and green. NBI enhances visibility of vascular structures on the mucosal surface. NBI is the world’s only patented endoscopic light technology that enables effective targeting of biopsies not seen under white light, without the use of dyes or drugs. NBI is recommended as enhanced cystoscopy to increase detection and decrease recurrence. The app highlights the fact that Narrow Band Imaging is now on the AUA/SUO 2016 Non-Muscle Invasive Bladder Cancer Guideline as well as having qualified FDA Claims. The intention is twofold to demonstrate how easy NBI is to use to show the effectiveness of narrow band imaging to aid in the visualization of vascular lesions. The Olympus NBI Virtual Reality app “The NBI Experience” is a gamified Virtual Reality simulation experience where you travel inside the bladder to visualize potentially cancerous lesions toggling between White Light and Narrow Band Imaging technology.
