Wiki: Troubleshooting Multicast
-
I understand what needs to be changed. I’ve already added it, but I’ll admit I haven’t tested it.
If you’d be willing and report back if it’s helping.
I’ve added two parts.
First is the Multicast Address to use. If it’s set, it should specify what to use, though I’m not 100% sure if th init needs to be directed as well, which I’m guessing it may be.
Second is the Multicast Port Override. Normally FOG creates tasks and it randomly generates a new port to allow multiple sessions as needed. However the override will not use random ports and will always use the override if set.

I’d like to try it out. Where can I find the installer?
I’ll report back on how it goes. -

I was able to get the version in Fog_Trunk going.
I saw the new multicast settings, that’s great.
Did have a few problems with NFS service, but I got them sorted out. The installer changed my configuration in /etc/exports and added a line to a directory that didn’t exist. I got rid of that, and set the settings back the way I had them for ProxyDHCP, then restarted NFS and all was well.
After that, I double checked the other files that I made custom changes to and they were all fine. I input my multicast settings & port number. Then gave the FOG server a reboot for good measure.
I created a multicast task to one client (a group with just one machine in it), and tried… and it doesn’t work…
Got the same issue I had before. It gets to the partclone screen and just sits saying
"Starting to restore image (-) to device (/dev/sda1)
inside /opt/fog/log/multicast.log there aren’t any new errors… just old ones from the 13th saying “StorageNode Not found on this system.” I think that error was from when I was still figuring out how to get NFS, and FTP to work right for the imaging process…
Keeping in mind that unicast works for uploading & downloading… My images move from the /images/dev folder to the /images folder properly via FTP (that was a hard one to fix).
Where should I look next? OR, Tom Elliott, would you like to mess with the multicast feature more? I understand you made these changes YESTERDAY, and man are you quick! So there might be a glitch somewhere you overlooked… I’ll be patient, because you guys are awesome.

Can you PM me your Gmail Address?
I can try working out issues directly as these kinds of troubleshooting is much more useful in near realtime communications.

This issue has been resolved. Tom got me going, big thanks!
I’ll be getting my installation documentation up on the wiki soon.

i am having this issue with multicast . upload/download images works ok ,but not multicast.
i do see one error that might be related and might not : “populating /dev using udev: udevd[2166]: error creating epoll fd: function not implemented”
any thoughts are welcome.
thanks

Have you tried the refereed to wiki documentation yet?
[url]http://fogproject.org/wiki/index.php/Multicasting[/url]Try the 1 client and then the 2 clients and please let us know of your results. [U]Usually[/U] we find that it is an environment setup issue and no an issue with Fog.

i havemanualy managed to send the log file to two clients , that went well, but gunzip recieve command just loaded the partiton image 0.6.9 inteface instead of recieving the file

Do your [U]ALL[/U] network switches currently have portfast enabled? or is STP disabled?

simple 10/100 switch [url]http://www.tp-link.com/en/products/details/?model=TL-SF1016DS[/url]
just one , the server and the clients -
[SIZE=3][FONT=Arial][COLOR=#333333]seems like a ‘dumb’ switch (“No configuring is required.”) so you are using fog as your dhcp also? you may want to try another switch, crossover cable test, or try using dnsmasq.[/COLOR][/FONT][/SIZE]
