      The problem with making that configurable is that it’s set in the boot image, which would need to be built for it. There are methods that could be used to pass this setting along from the web server to the boot image, but I don’t think it’s been considered a priority, and that would be a non-trivial change.

      As for the half-duplex networks… there are some older network printers are statically set to half-duplex, and unfortunately not all businesses provide sufficient IT budgets for replacing devices that aren’t “broken”.

      I would suggest that you make a feature request for the change… unfortunately there is no dedicated feature request tool currently in use, so your best bet is to just make a thread in the Developer forum with Feature Request in the title. Or if you’re comfortable attempting to write the feature yourself, pull down the latest SVN and go for it, and pass it on to the developers once you’re done so they can work with you on getting it into the next version.

        ok, I understand that…

        we are talking about multicast 😉
        Every printer will surely slow down the transfer if igmp isn’t used etc.
        The question was why anyone is using hubs and not switches.

        or I will keep patching it by hand every release 😉

          How much better does multicast perform after this change?

            mmh, it’s quite a while ago that I tested it - don’t know any numbers anymore but it was enough to say that I will patch the files after each release again 😉

            I can’t test it currently because we’ve upgraded our network and now the server and the clients are the bottleneck (5 GiB/min for Multicast and full 1 Gbit/s for NFS - with decompressing on the client).

              haha must have been good enough then, so all i have to change is [COLOR=#000000][COLOR=#dd0000]–half-duplex [COLOR=#000000]to[/COLOR] --full-duplex [COLOR=#000000]?[/COLOR][/COLOR][/COLOR]

              i may just give that a test, cheers

                is it really as simple as changing --half-duplex to --full-duplex?

                  So another question I have, for unicast, or imaging 1 device, is that set to half-duplex or is it set to full-duplex?

                    would be great to have the higher speed confirmed.
                    Setting it on the FOG-Server should be sufficient - it’s a udp-sender option and not udp-receiver 😉

                    Unicast is handled over nfs, not udp-sender

                      Jtb, you’re right. I don’t know why I thought that was in the boot image.

                        Have you tested it yet?

                            just done a quick test, after editing the MulticastTask.class.php my multicast speed was at 580-590/mb min. When set back to half duplex the multicast was at the normal (for this network) 670mb /min
