Udp-Sender: half-duplex?
-
[quote=“BryceZ, post: 1684, member: 2”]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.[/quote]
ok, I understand that…
[quote=“BryceZ, post: 1684, member: 2”]
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”.[/quote]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.[quote=“BryceZ, post: 1684, member: 2”]I would suggest that you make a feature request for the change… […][/quote]
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[quote=“Kevin, post: 1720, member: 3”]So another question I have, for unicast, or imaging 1 device, is that set to half-duplex or is it set to full-duplex?[/quote]
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?
-
no not yet, if I get time today I will post back my findings
-
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
