redleader Posted January 18, 2017 Report Share Posted January 18, 2017 So, I.T. have changed our Network setup, again ... We now have 3 network ranges within our company; 10.122.133.1 ... 255 fixed wired ethernet desktops 10.122.132.1 ... 255 fixed wired ethernet servers 10.122.134.1 ... 255 wifi laptops Users could be on any of these. 255.255.255.192 subnet for all Retropsect Server is on 10.122.132.20 So I need to lock-on and track the Retrospect Clients for Mac Desktops or Laptops across these IP ranges using my Retrospect Server for ac OSX Server. Can I do this? Some setup in Retrospect->Preferences-?Network ? Thanks for you help, Mac OSX Desktops 10.10 to 10.12 Mac OSX Server 10.11.6 Retrospect Server for Mac 12.5.0 (111) Quote Link to comment Share on other sites More sharing options...
DavidHertzberg Posted January 18, 2017 Report Share Posted January 18, 2017 I am but a lowly home user, with a single Internet-facing router. However I am capable of reading the Retrospect Mac 13 User's Guide (the Mac 12 UG, which you can download, should be similar in this area). Try "Subnet Broadcast" on page 92, and "Configuring Network Interfaces and Subnets" on pages 94 and 95. For Retrospect User's Guides, the Table of Contents is your friend; if that doesn't help, try the Find function in your Web browser. Speaking of friends, the ever-friendly Mayoff (who is head of Retrospect Inc. Tech Support) put a video tutorial about this on YouTube in 2011. In other words, I suggest you learn to find documentation by clicking the icons at the bottom of this page. Good luck! Quote Link to comment Share on other sites More sharing options...

Then I don't understand what you mean by "lock-on and track the Retrospect Clients for Mac Desktops or Laptops across these IP ranges". Does "Configuring Network Interfaces and Subnets", on pages 88 and 89 in the Retrospect Mac 12 User's Guide, not do what you need? What precisely is your problem?

DavidHertzberg Posted January 19, 2017 Report Share Posted January 19, 2017 On the other hand, maybe there is a problem with your subnet mask. I'm extremely rusty, as well as inexperienced, in that area. However, by specifying 255.255.255.192, aren't you saying that any client with an address of 10.122.13n.(evenly-divisible-by-32) isn't in your range? Or do I just not know what I'm talking about? Most people use 255.255.255.0 as a subnet mask. I suggest you talk to your I.T. people. P.S.: Changed address range at the end of third sentence of my first paragraph. I haven't actually used hexadecimal notation in the last 45 years, so I made a stupid mistake. P.P.S.: In the video linked to in post #2 in this thread, Mayoff specifies a subnet mask around minute 0:25. He specifies 255.255.255.0. In general, Mayoff makes it a practice never to explain in one of his Retrospect videos why he is doing something. I believe he does that because he has found, by bitter experience, that any explanations in a video tend to lose the viewer. However Mayoff's lack of explanation in videos has, on occasion, proved to be a problem. Nevertheless, if he specifies 255.255.255.0 as a subnet mask, IMHO you'd better have a pretty good reason for specifying 255.255.255.192 instead. It might be a good idea for you to go to this Web page, and use it to either send an e-mail or phone Retrospect Inc. Support. Quote Link to comment Share on other sites More sharing options...
DavidHertzberg Posted January 20, 2017 Report Share Posted January 20, 2017 Yes, after a search of the Ars Technica Networking Matrix forum, it does appear I know what I'm talking about. Look at this post there, from 2001. Now look at the third paragraph. Note that it says "The subnet mask 255.255.255.192 in binary is11111111.11111111.11111111.11000000The zeros represent your 62 available host addresses." That's 62 available host addresses, not 63. The reason for this is that a host address (what you get after flipping the ones to zeros and vice-versa in the subnet mask and then ANDing that with the address) which evaluates to all zeros is not a valid host address. So when I said in post #5 in this thread "any client with an address of 10.122.13n.(evenly-divisible-by-32) isn't in your range" of host addresses, I'm correct. If your problem is not being able to "lock-on and track the Retrospect Clients for Mac Desktops or Laptops across these IP ranges" for certain clients, that may be the answer. The solution would be to use 255.255.255.0 as your subnet mask. Quote Link to comment Share on other sites More sharing options...
DavidHertzberg Posted January 20, 2017 Report Share Posted January 20, 2017 On second thought, even more important is what is on page 93 of the Retrospect Mac 13 User's Guide: "According to TCP/IP standards, every subnet has both a network address and a subnet mask, such as 192.168.1.0 and 255.255.255.0. Routers use these to identify the physical network to which computers are connected. Routers also support queries [my emphasis] to all the computers on a particular subnet." You have 3 physical networks within your company: 10.122.132.1 ... 255, 10.122.133.1 ... 255, and 10.122.134.1 ... 255; the network addresses are denoted by the first 3 sets of digits in each address; 10.122.13n. So by making your subnet mask 255.255.255.192, you are telling Retrospect to broadcast to physical networks that don't exist in your company. Again, use 255.255.255.0 as your subnet mask.
