Yes I did fix this problem! I downloaded a different (newer) kernel and used that, worked a charm. Don't remember it being a kitchensink version. Good luck Cheers -Stu
-
Plus it also then goes onto say 'hard disk not found!' So not sure what to do there also! Possibly change some kernel arguments I read somewhere if you could spare a moment of knowledge there? Cheers -Stu

Thanks for your reply morganw, I have installed FOG version 0.29 and I see that the kernel gets downloads after the PXE boot. I don't see anywhere it display the version that it is included with the 0.29 version. I shall keep an eye out again for any numbers popping up. I might try kernel version 0.24 as you suggest or another new version, I am currently having issues booting some new Netbooks (Samsung N145). They PXE boot just fine, when they have pulled down the bootstrap images/kernel then it gives me some errors of... found HQ with no IRQ check BIOS/PCI init 0000:00:1d.7 fail, -19 a few times then... IP-Config: No network devices available. So from what I gather here, the network card isnt supported somewhere! Cheers -Stu

It is a layer 3 managed switch and there are a number of options when it comes to this, such as broadcast storms and such like. If I had more time to look into the problem then I might do but for now just having it disabled so far hasn't upset anyone Will soon see if it causes any other issues, there shouldn't be any other multicast/broadcast traffic on the network to disrupt normal traffic flow. Essentially when running multicast traffic/tasks with this setting turned off it denies service to other hosts. Cheers -Stu

I have a similar problem in that I cannot see any options in the Kernel Update page in the FOG management. I am not behind a proxy and using a virtual machine with bridged access to the network/internet so should not be an issue. Is there a reason or where can I look to get the kernels to show without manually downloading them and renaming them? Is this where you get them all from... FOG - A Free Cloning Solution - Browse /Kernels at SourceForge.net and how do you check what the current Kernel version you are using? I have not seen it anywhere yet..? Cheers -Stu

Ok quite a simple fix for this one.... The 3Com switches were stopping all the multicast traffic on them. The hosts were joining the session but of course when it started boshing out all the multicast traffic they didnt get it, sat there and timed out. Went into the switch config and changed IGMP snooping to be disabled and multicasting works a treat. This although does unfortunatly have a downside in that during a multicast task, the whole network gets bombarded with traffic, so it seems. Luckily in this scenario when these tasks will be executed there will be no other users Although I thought IGMP snooping would be able to be enabled for this process to work correctly and only filter out the traffic to the ports relevant to the multicast? Hmm? Cheers -Stu
-
Any information on how to do this would be extremely useful? Any ideas if you can? Cheers -Stu
-
Shouldnt IGMP snooping be disabled and not enabled in this case? Because you dont want the packets to be filtered...? Cheers -Stu

I get you, It happens before the multicasting process starts. From looking at the logs it registers the clients joining the session and then it waits a short time.... one of the clients drops out and it states it is disconnected in the log. The multicast image is started but only with the one machine (I am currently only multicasting to two machines on two different switches) Both switches are managed layer 3 48port buggers so may need to check some config within them Not got that far yet in the investigation as I was using v0.30 with no success. Suggesting its an ownership or timeout issue.... I remember seeing someone with a similar issue and change the MySQL connection timeout to something higher. I will try this and your suggestion and report back Thanks for your help BigDaddyTeemoe -Stu

Thanks very much, I shall give your suggestions a go tomorrow By changing the image type, from what I remember I have already given the whole of that directory root access but will check also. Did you have it successfully multi-casting to computers plugged into different network switches? I shall post my findings Cheers -Stu

BigDaddyTeemoe, over the last few weeks I have been using FOG version 0.30 and not once had a successful multicast over a physical network. It has only ever seemed to have worked to virtual machines (at that is it multicast as they were travelling down one switchport!). I would stick with 0.29 personally but good luck with 0.30 if you do decide to go down that way. Cheers -Stu
-
I am also getting this error unfortunately. In the logs it looks like this client times out just before the process is then started. They are being casted through 2 different switches and it worked when the machines were all plugged into the same switch. Running for v0.29 and Ubuntu 10.04 It would be useful to find a solution to this Cheers -Stu
