Puppet

Normally to update the host (instead of waiting for the timer)

sudo puppet agent --test

Host stops reporting, wont fetch anything

Usually when someone has stopped puppet - done lots of changes, potentially deleted the branch it was configured with.

Ensure that the /etc/puppetlabs/puppetpuppet.conf files environment is correct

[main]
vardir = /opt/puppetlabs/puppet/cache
logdir = /var/log/puppetlabs/puppet
rundir = /var/run/puppetlabs
ssldir = /etc/puppetlabs/puppet/ssl

[agent]
pluginsync      = true
report          = true
ignoreschedules = true
ca_server       = puppetmaster.domain
certname        = thishost.domain
environment     = develop
