Please add "--max-bitrate" option...

[Wayne Workman]

@Jean-Jacques-Morda As a side thought to all this,

Because you have a 1000/100 mixed environment, maybe you should not group your machines just by model…

Maybe… say… you have a building full of nothing but Dell 9020s.

So… You’d actually have two different groups for those… 9020s with gig, 9020s without gig… Don’t mix computers with different link speeds… keep them separated in their own groups - this should solve your issues.

[Jean-Jacques Morda]

@Wayne-Workman In fact, it’s more complicated than that… i have many different switches with many different links / configurations on many different machines (mostly HP), somewhere computers in one room was connected to two or three different switches and some of switches are not configured by me but by another service that did not understand our needs. So i’m only in charge of my own switches but not VLAN ones. Some computers are far far away from the server and multicast transits in many many switches configured in differents ways because computers network card don’t act the same way if half/full duplex enabled generating lot of collisions… so, if the speed is not limited by 80m max-bitrate, timeouts rules the network traffic and udpsender no longer follows.

[Jean-Jacques Morda]

@Wayne-Workman but with --max-bitrate 80m, my 160gigs images are working like a charm with multicast download in our classrooms ! I’m happy with that.

[Wayne Workman]

@Jean-Jacques-Morda Understood… It does sound complex. But, I’ll add that - instead of dealing with the complications of multicast, you are highly likely to get them all imaged in roughly the same amount of time if you simply just used unicast.

Plus, there are incredible speed boosts in FOG Trunk. I can deploy a 40GB image to a machine in 5 minutes.

[Jean-Jacques Morda]

I’m cloning a classroom, 160 GO image in 2 hours. That is satisfactory for a so bad network such mine …

I’ve implemented the requested feature, but I do NOT know if it will work.

To set the bitrate, it’s a Per Node (master of course) setting.

You can set it how you see fit, appropriate to the way it’s set to the command. meaning you can setup the variable with 1000000, 1000k, or 1M

[Jean-Jacques Morda]

@Tom-Elliott Thank you, i’ll check the git to learn how you add it by the way and telle you results of my tests. I’ll check all of that tomorrow.

[Jean-Jacques Morda]

@Tom-Elliott Ok, don’t find the bitrate option until i remember it’s a master node option… tested and glad to see the new option appear in the udpsender command ! Thanks again.

I saw the new option on a system I was helping with last night… I didn’t know what to set it to, lol.

So I set it to 1000000

[Jean-Jacques Morda]

my needs is 80m so i set it to 80m and all is ok now for my network !!!

That means you limited its speed to 1Mbps.

You can set by 1000000 (bit)
You can set by 1000k (kilobit)
You can set by 1m (megabit)

[Wayne Workman]

@Tom-Elliott crap.

[Wayne Workman]

@no1bossman You might want to stick an “m” in the max bitrate field for the storage node.

[Wayne Workman]

@Tom-Elliott What happens if the field is left blank?

[Tom Elliott]

–max-bitrate is not set and udp-sender auto selects the speed.

[Jean-Jacques Morda]

@Wayne-Workman yes, it detect the max theoretical speed… like speed on road. On road, sometime, we have to slow down to avoid accidents, if not, cars does not arrive to destination.

[Jean-Jacques Morda]

Hehe, don’t want to abuse but is a “per group” --max-bitrate option is possible ? Some computers groups are connected to a part of the network that need to be limited with --max-bitrate and some others not. Not very important but it will avoid to change master node setting when we launch cloning with another group. I suppose it’s a little bit more complex to implement
