Introduction
This is a selection of problems that can be quickly solved.
Ubuntu
Too many network interfaces
If the following appears in /var/log/syslog:
avahi-daemon[1113]: IP_ADD_MEMBERSHIP failed: No buffer space available
It's probably because you've too many network interfaces. This can easily happen with docker. You can check your current configured maximum using this:
sysctl net.ipv4.igmp_max_memberships
You can increase that amount using the following command:
sysctl -w net.ipv4.igmp_max_memberships=50
