Multicast problem with fog 1.5.7 ubuntu server 18.04.3 and aruba switch

[dario.vettore]

Hi all.

As I write in the description I have some problems doing multicast with fog.

My configuration is:

• 106 computers
• ubuntu server 18.04.3
• fog 1.5.7
• switch Aruba 2930M 48G (4 in stack)
• snooping activated

when I start the multicast task, partclone don’t start and I must poweroff all the computer manually.

Any Ideas?

Thanks Dario

@dario-vettore Try testing aß suggested in the wiki: https://wiki.fogproject.org/wiki/index.php?title=Troubleshooting_a_multicast

Are you sure there is no firewall between FOG server and the clients??

@Sebastian-Roth

yes, they are in the same VLAN

I try also this:

udp-sender --file /opt/fog/.fogsettings --log /opt/fog/log/multicast.log --ttl 1 --nopointopoint --portbase 9000

with this:

nc -u 10.1.10.164 9000

but I have no answer

there is no error in /aparche2/error.log

@dario-vettore Are clients und FOG server all in the same subnet und same VLAN?? Please post more details about your network layout.
