I have work with databases such as Digital RDB (later to become Oracle RDB), Oracle DBMS, Microsoft SQL Server, MySQL and PostgreSQL on VAX, Alpha, Sun and Intel.Ĭheck out my professional profile and connect with me on LinkedIn. ![]() I have programmed in 8-bit assembly language on 6502, FORTRAN and COBOL on IBM System/370 (and I still hate JCL), VAX BASIC and COBOL (and a weird and massive WordPerfect 4.0 macro) on DEC VMS (Alpha), C/C++ on Digital Unix (ALPHA), and C/C++, Perl (it may be powerful but I still hate it), PHP on Linux (Red Hat, Centos, Ubuntu, etc.). I’ve been around information technology since 1983 with computers such as DEC Rainbows (weird machine – the standard DOS couldn’t format its own floppy disks – remember them? – and I had to format them on a friend’s IBM PC) to Radio Shack TRS-80 to Apple ][e and Apple //c in the beginning. One important thing to remember: If you statically set the IP addresses of your UniFi devices you will not get the DHCP Option 43 provided to the devices. Browserling has a page to convert the IP address to hex: Convert IP Address to Hex Format. You have to add 01:04 to the hex version of the IP address of your UniFi Controller. In my DHCP configuration (on pfSense), I added DHCP Option 43.That way when a device restarts (such as after a reboot, power loss) it can find the controller when it boots and executes the set-inform The hostname unifi will resolve to my UniFi Controller. I configured my DNS server with an alias that allows unifi to resolve to the UniFi Controller. ![]() The option that I took, or maybe it is two options, is: There are a number of ways that this can be resolved (other than putting the Controller on the same subnet) as documented in UniFi – Device Adoption Methods for Remote UniFi Controllers. The problem, if you will, with this configuration is that when a UniFi device looks for the UniFi Controller is that is cannot find the Controller on a different subnet. Here is the scenario: My UniFi devices are on a separate subnet from my UniFi Controller. This is, as always, is maybe more of an aide-mémoire for me, but may be helpful if someone else is searching for a solution…
