Multicast not working on 1.3.0-RC-5 SVN Revision: 5943

[LibraryMark]

Folks - I am using Version 1.3.0-RC-5 SVN Revision: 5943 on Ubuntu 16.04.1 LTS. Unicast imaging works fine, but multicast does not. I am on the trunk version because I could not get 1.20 to install on 16.04.

The PC’s do come on, but they say:

Attempting to check in…failed
No active task for Host: (…)

And this goes on forever.

When I look at the “Active Multicast Tasks” page it says “No results found”.
In the “Active Tasks” page the two machines that I put in my test group are there.

Before I upgraded, the version I was on , 0.32 i think, multicasted just fine, so I don’t think there are any networking issues.

After starting the multicast session, the multicast log just says,
[08-03-16 12:17:57 pm] | This is not the master node
every 10 seconds forever.

What should I be looking for?

Did you follow the 16.04 installation instructions?

[LibraryMark]

This is the command line I used: php_ver=‘7.0’ php_verAdds=‘-7.0’ ./installfog.sh

That is the only change I made. Is there something I missed?

[LibraryMark]

BTW, the groupmanager.log file needs a newline put in after each entry. It’s a little hard to read right now.

I did not do this with mysql:
ALTER USER ‘root’@‘localhost’ IDENTIFIED WITH mysql_native_password BY ‘’;

Is there a reason we would want anyone to login with root and no password?

Still no luck. I am using a VM so I wiped it out and started over. Completely stock 16.04 install, nothing but SSH installed. Installed subversion, then

svn co https://svn.code.sf.net/p/freeghost/code/trunk /root/fogproject

Ran the install from /root/fogproject/bin with:

php_ver='7.0' php_verAdds='-7.0' ./installfog.sh

It never asked me for a password for the MySQL install so I assume it is blank when the install script asks me if it is. When I get to the part where it says to go to the browser and hit a button, I do this first from another ssh session:

"ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '';

Then go to the browser and hit the button.

Then I copy my disk images from my original server.

After that I download the database backup from my original server. It says it’s running version 7909, and import them into the new server.

Am I running into issues with my backup?

Alternatively, would I be better off running a different version of Ubuntu? Which one? Which version of Fog is the safest? This whole thing started when I got some PC’s that would not boot off the kernel that 0.32 had. I was perfectly happy with that version and everything worked and was rock-solid. I just want to be able to multicast again.

[Tom Elliott]

@LibraryMark 7909 is extremely old, in comparison.

Now that you’ve made the 16.04 progress (the mysql native bit), you can fix the “version” issue.

Run this command please: (If you have custom data in the fog folder back them up please.)

rm -rf /var/www/fog /var/www/html/fog

Then rerun the installer.

No. 16.04 will have the longest support period and runs fog just fine.

Which version of Fog is the safest?

The latest RC is more stable than the official stable version at this point, and will work with the most hardware. The devs are just making very sure everything is good with it, and we appreciate you coming here with this issue.

I just want to be able to multicast again.

We have troubleshooting articles on multi-casting. Please read through them and try the testing steps:

Finally got it working. I had to completely wipe my install and not try to import anything from my old server. Now I have to go around and re-register all my PC’s but I’ll gladly do that so than I can image them all at the same time.

Thanks for all your help. FOG is a true lifesaver!

@LibraryMark If you had the new client deployed, they would register themselves, and show up as pending hosts for you to approve. Just an FYI.

Also - if exporting the hosts list isn’t working for you, we need to figure out why and fast. I can help you figure out why - please message me and we can do a Team Viewer session and I’ll figure it out. I won’t break what you’ve done so far, either - I’m actually pretty good at this.

Thanks for the offer, Wayne. I put in some extra fields int the host table, like hostHomepage and hostScreenWidth and such. Might that be causing the problem?

@LibraryMark You could have pulled the same SVN version as on your old server, installed that, imported your DB and then upgrade to RC6, but glad you got it working anyway.
