There are one master and one agent in my environment.

192.168.11.12 puppet-master

192.168.11.13 puppet-agent01

puppet-master

# dpkg -l | grep puppet ii  puppet-common                       3.4.3-1                       all          Centralized configuration management ii  puppetmaster                        3.4.3-1                       all          Centralized configuration management - master startup and compatibility scripts ii  puppetmaster-common                 3.4.3-1                       all          Puppet master common scripts

agent

# dpkg -l puppet ii  puppet         3.4.3-1      all          Centralized configuration managem

Assumes that you have installed the master and the agent.

on the master

/etc/puppet/files is a directory to transfer files to agents.

# ls /etc/puppet/files root@puppet-master:~#

You can define this directory in /etc/puppet/fileserver.conf

on the master

root@puppet-master:~# grep -v ^# /etc/puppet/fileserver.conf [files]  path /etc/puppet/files  allow * [plugins]

I added “allow *” in the [files] section to allow agents to get files

restart the master

root@puppet-master:~# /etc/init.d/puppetmaster restart * Restarting puppet master                                              [ OK ]

create a file on the master

root@puppet-master:~# echo "hello world" > /etc/puppet/files/helloworld.txt root@puppet-master:~# root@puppet-master:~# cat /etc/puppet/files/helloworld.txt hello world

here is a manifest file.

on the master

root@puppet-master:~# cat /etc/puppet/manifests/site.pp node "puppet-agent01" {    file {"/root/helloworld.txt":        ensure => file,        owner => "root",        group => "root",        mode => 0644,        source => "puppet://puppet-master/files/helloworld.txt"    } }

on the agent

the agent got the file from the master.

root@puppet-agent01:~# puppet agent --verbose --no-daemonize --onetime Info: Retrieving plugin Info: Caching catalog for puppet-agent01.tcv.jp Info: Applying configuration version '1410190960' Notice: /Stage[main]/Main/Node[puppet-agent01]/File[/root/helloworld.txt]/ensure: defined content as '{md5}6f5902ac237024bdd0c176cb93063dc4' Notice: Finished catalog run in 0.22 seconds root@puppet-agent01:~# root@puppet-agent01:~# cat /root/helloworld.txt hello world

the agent connected to the master over TCP dst 8140

root@puppet-master:~# tshark -n -r a.pcap -Y '(tcp.port == 8140)' Running as user "root" and group "root".
