Since you can get into the Web UI and start a task fine, does /opt/fog/service/etc/config.php has the same database name as /var/www/fog/commons/config.php?

If so, that’s all i can think of for now.

brian_ · Nov 8, 2012, 7:09 PM

had to reinstall and now he is whats happening.
the php command listed above still works and completes successfully
when i make a group and give it a multicast task it disappears in the task listings

/opt/fog/service/etc/config.php
define( “MYSQL_HOST”, “localhost” );
define( “MYSQL_DATABASE”, “fog” );
define( “MYSQL_USERNAME”, “root” );
define( “MYSQL_PASSWORD”, “” );

/var/www/fog/commons/config.php?
define( “MYSQL_HOST”, “localhost” );
define( “MYSQL_DATABASE”, “fog” );
define( “MYSQL_USERNAME”, “root” );
define( “MYSQL_PASSWORD”, “” );

i will try the multicast by giving it the task while it’s waiting for one. that normally works.

now that i have fixed the mysql password and the tftp password and i now get the “I could not connect!” doing the php command

i tried changing the /etc/hosts

127.0.0.1 localhost
192.168.155.69 T412-fogserver

and still no luck

maltobelli · Nov 9, 2012, 4:27 PM

System error 111 is connection refused. Is your MySQL server configured to allow connections from IP’s other than 127.0.0.1? Does using define( “MYSQL_HOST”, “127.0.0.1” ); allow the PHP code to connect?

That IP should almost always be 127.0.0.1 or localhost, since each invidual client does not actually connect to the MySQL server themselves.

brian_ · Nov 9, 2012, 4:50 PM

changed both configs back to 127.0.0.1 and i now get new messages in the multicast log file.

still does not work

if it isn’t working , could you also check the udpcast log , to see if clients are connecting successfully or not.

maltobelli · Nov 9, 2012, 5:09 PM

You typed in upcast, it is supposed to be udpcast.
[CODE]tail -f /opt/fog/log/multicast.log.udpcast*[/CODE]

Post #13 suggests there is an issue starting UDPcast, Is eth0 the correct interface and is not disabled? Do you have SE Linux or a firewall running?

Run this (taken from the multicast log in post #13)and see what error it gives you
[CODE] gunzip -c “/images/win7dual2/d1p1.img” | /usr/local/sbin/udp-sender --min-receivers 2 --portbase 63106 --interface eth0 --half-duplex --ttl 32 --nokbd;gunzip -c “/images/win7dual2/d1p2.img” | /usr/local/sbin/udp-sender --min-receivers 2 --portbase 63106 --interface eth0 --half-duplex --ttl 32 --nokbd;gunzip -c “/images/win7dual2/d1p3.img” | /usr/local/sbin/udp-sender --min-receivers 2 --portbase 63106 --interface eth0 --half-duplex --ttl 32 --nokbd;[/CODE]

also is there an easy way to switch eth0 with eth1? i need it on 1 and not 0

maltobelli · Nov 9, 2012, 5:59 PM

There is not an easy way that i’m aware of. But in the web settings(FOG_WOL_INTERFACE, FOG_UDPCAST_INTERFACE, FOG_NFS_ETH_MONITOR) and in the two config files switch all the eth0’s with eth1’s. And restart the FOGMulticastManager and FOGScheduler.

There may be more you need ot edit for each of the services if they are configured to listen on only one interface.

I havn’t tried this but perhaps editing “/etc/udev/rules.d/70-persistent-net.rules” and swapping the eth0 and eth1 for the devices, then rebooting would swap which one is which. This may break other things that are depending on specific interfaces though(other services/uses for the server).

Please Wait...
