Hi, I have installed a FOG server on Ubuntu. WOrks really well on unicast, takes about 15mins to image a machine. However, when I try unicast, it does work, but the send speed drops to about 5mbps, and reckons it will take 36hours!
I thought multicast was supposed to be just as fast as unicast? Multicast is working, just extremely slowly. It looks like queueing the imaging with 1 or 2 at a time will be faster!
Machine specs aren't great, 2.8Ghz with 512mb ram. 100mbps network.
Any thoughts? Thanks in advance.
I've not used FOG so I'm not sure how well it does multicast. The wiki says "Multicasting in FOG may require special switch configuration." which is a wonderful get out clause :-)
typically, you need to look at IGMP snooping on your switches - it should be enabled to allow multicast to work well.
Thanks srochford. Gotta admit, routers and switches scare me, not really sure what to do with them. No worries, I'll just use fog to do a unicast, but queue them up a few at a time. Won't be as fast as multicast working properly, but probably faster than multicast not working....
Thanks for your help anyway. :)
