    I use FOG 1.2 now and am just going over some of our labs that we use FOG in. For many of them, we seem to be able to multicast fine but for a couple we can’t.

    All hosts will sit at the blue screen waiting and nothing happens.

    I checked the multicast log and apparently all 31 hosts have timeout notAnswered and notReady and eventually are just all dropped.

    [CODE]Udp-sender 20120424
    Using mcast address 234.1.63.202
    UDP sender for (stdin) at 10.1.63.202 on eth0
    Broadcasting control to 224.0.0.1
    New connection from 10.9.110.68 (#0) 00000009
    New connection from 10.9.110.172 (#1) 00000009
    Starting transfer: 00000009
    Timeout notAnswered=[0,1] notReady=[0,1] nrAns=0 nrRead=0 nrPart=2 avg=10000
    Timeout notAnswered=[0,1] notReady=[0,1] nrAns=0 nrRead=0 nrPart=2 avg=10000
    Timeout notAnswered=[0,1] notReady=[0,1] nrAns=0 nrRead=0 nrPart=2 avg=10000
    Timeout notAnswered=[0,1] notReady=[0,1] nrAns=0 nrRead=0 nrPart=2 avg=10000
    …
    [/CODE]

    I’m not really sure where to start but what happened to /opt/fog/service/etc/config.php? I was going to try and increase UDPSENDER_MAXWAIT - but this doesn’t even exist in there. Is there any way to increase the timeout at all somewhere?

    Cheers

      The config for the FOG Services (FOGMulticastManager,FOGScheduler,FOGImageReplicator) fields are now done in /var/www/fog/lib/fog/Config.class.php

      The /opt/fog/service/etc/config.php only tells the services where the webroot is for the system.

      Hopefully that helps.

      That said, the timeout can, at least in SVN and possibly 1.2.0 be set by the database.

      Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG! Get in contact with me (chat bubble in the top right corner) if you want to join in.

      Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log)

      Please support FOG if you like it: https://wiki.fogproject.org/wiki/index.php/Support_FOG
