Multicast problem with 1.3.0-RC-8 ?

  • Hi everybody :-)

    I’m installing a new fresh Fog Server on a Debian 8.x (the previous was perfect, but the system disk died 0:-) ). Your work on Fog 1.3 is incredible, you made a very great job !

    Managing computers, groups, uploading images (…) : all is ok, but not multicast :-/ When I make a multicast task, I have errors like “invalid multicast session” or “attempting to check in”. Here are the logs from /opt/fog/log/multicast.log ; the “Array” PHP error just after “–interface” looks very suspect…

    Do you know where is the problem ?

    My Fog version is SVN Revision 5952 :

    commit a84bdebfe1b1149829cf14e745ae1f086b34ef14

    Fix issue of hosts not able to search. Maintain as 1.3.0-RC-9.

    Thank you for your help !

    Confirmed the capture issue and this has since been fixed in RC-10.

    Solving as the multicast issue was already confirmed fixed.

  • @Wayne-Workman It’s a luck that upgrading and downgrading Fog is so easy :)

    I confirm with running Version 1.3.0-RC-9 (SVN Revision: 5952), I can make capture. It works perfectly (but multicast is still broken ^_^).

  • @JiC Can you move back to RC-9 and see if capture works?

  • @Tom-Elliott Thank you so much :-)

    I tried the “version 19” from branch “working-RC-10” (SVN Revision: 5953). The problem with the multicast is solved, you rule !!!

    But when I tried to capture a new image, the upload doesn’t work anymore (I have an error like “Mounting file system : failed”). I think the problem is more general, because when I start capture in “debug mode”, I can see many settings are not defined :


    (uploading was ok yesterday)

  • Senior Developer

    @JiC to ease you a little it’s already been patched

  • Hum, yes you’re right, I’m already in RC-9, I don’t know if the problem was in RC-8 too. I’ll wait for the next release, I hope for you this will not be too hard to patch ;-)

    With my encouragement !


  • Senior Developer

    Issue was actually in RC-9, possibly RC-8 as well, but as he stated SVN Version was 5952 (which is rc-9) It wasn’t too hard to find or correct.

    RC 10 will have this fix (which I probably will release tomorrow evening is you’re looking for a spoiler).

  • Upgrade to rc-9 first. Then look in the wiki for “Troubleshoot Multicast”
