Can't use multicast on FOG 1.2.0 help please!

[tennosuke]

Hi, my problem is that i cannot use multicast on the clients, i’ve tried it with a host and with a group, didn’t work in both cases.

I’ve tried this also : https://wiki.fogproject.org//wiki/index.php?title=Troubleshooting_a_multicast#Troubleshooting

And works perfectly, u can see the log :

$ tail -f /opt/fog/log/multicast.log
11:17:12.804261 Using mcast address 232.158.158.51
11:17:12.805397 UDP sender for /opt/fog/.fogsettings at 192.158.158.51 on eth0
11:17:12.805783 Broadcasting control to 224.0.0.1
11:19:33.254858 Starting transfer: 00000009
11:19:33.283621 Transfer complete.
11:19:33.286490 Disconnecting #0 (192.158.158.12)
11:19:33.288428 Disconnecting #1 (192.158.158.16)```

But if i try with a multicast task nothing happens:

I didn’t make any change on multicast settings… i don’t know if i should make some change in the Config.class.php file or what…

My fog settings are:

ipaddress="192.158.158.51";
interface="eth0";
routeraddress="         option routers      192.158.158.18;";
plainrouter="192.158.158.18";
dnsaddress="    option domain-name-servers      208.67.222.222; ";
dnsbootimage="208.67.222.222";
password="";
osid="2";
osname="Debian";
dodhcp="y";
bldhcp="1";
installtype="N";
snmysqluser=""
snmysqlpass="#####";
snmysqlhost="";
installlang="0";
donate="0";
fogupdateloaded="1"

And the Config.class.php file (multicast settings) :

private static function svc_setting()
        {
                define( "UDPSENDERPATH", "/usr/local/sbin/udp-sender" );
                define( "MULTICASTLOGPATH", "/opt/fog/log/multicast.log" );
                define( "MULTICASTDEVICEOUTPUT", "/dev/tty2" );
                define( "MULTICASTSLEEPTIME", 10 );
                define( "MULTICASTINTERFACE", "eth0" );
                define( "UDPSENDER_MAXWAIT", null );
                define( "LOGMAXSIZE", "1000000" );
                define( "REPLICATORLOGPATH", "/opt/fog/log/fogreplicator.log" );
                define( "REPLICATORDEVICEOUTPUT", "/dev/tty3" );
                define( "REPLICATORSLEEPTIME", 600 );
                define( "REPLICATORIFCONFIG", "/sbin/ifconfig" );
                define( "SCHEDULERLOGPATH", "/opt/fog/log/fogscheduler.log" );
                define( "SCHEDULERDEVICEOUTPUT", "/dev/tty4" );
                define( "SCHEDULERSLEEPTIME", 60 );
        }

Thanks and sorry for my bad english

Ok… seems that something is wrong with the FOGMulticastManager… it stops, starting it again solved the problem.

sudo service FOGMulticastManager stop && sleep 30 && sudo service FOGMulticastManager start

Hello, I am also having the same problem in this version of FOG. Tennosuke, performed the procedure that you mentioned, but without success. Is there any other way to solve this problem?

I’m with Debian 7.9 32bit, identified in various forums, the most commonly used distribution is Ubuntu 12.02, but I have not done the test.

@rogwol make sure your interface name is correct.

ip link show

I have to admit that I see this kind of issue from time to time too. Usually I check the multicast log on the web interface and just restart the service if it doesn’t play nice.

@rogwol Are you sure seeing the same problem? Have you gone throught the troubleshooting guide and tried multicast by hand too? I am sure there is a way to solve the problem on your machine but you/we need to dig a little further I suppose. What do you see in the multicast log (web interface -> FOG configuration -> Log viewer)?

[Wayne Workman]

@rogwol Also check that FOGMulticastManager is running.

Probably something like service FOGMulticastManager status
