master branch 
This module manages Red Hat/Fedora traditional network configuration.
It allows for static, dhcp, and bootp configuration of normal and bonded interfaces. There is support for aliases on interfaces as well as alias ranges. It can configure static routes. It can configure MTU, ETHTOOL_OPTS, and BONDING_OPTS on a per-interface basis.
It can configure the following files:
- /etc/sysconfig/network
- /etc/sysconfig/networking-scripts/route-*
- /etc/sysconfig/networking-scripts/ifcfg-*
Class and Define documentation is available via puppetdoc.
Please note that the following examples do not depict all of the paramters supported by each class or define.
Global network settings:
class { 'network::global':
gateway => '1.2.3.1',
}
Normal interface - static (minimal):
network::if::static { 'eth0':
ensure => 'up',
ipaddress => '1.2.3.248',
netmask => '255.255.255.128',
}
Normal interface - static:
network::if::static { 'eth1':
ensure => 'up',
ipaddress => '1.2.3.4',
netmask => '255.255.255.0',
gateway => '1.2.3.1',
macaddress => 'fe:fe:fe:aa:aa:aa',
mtu => '9000',
ethtool_opts => 'speed 1000 duplex full autoneg off',
}
Normal interface - dhcp (minimal):
network::if::dynamic { 'eth2':
ensure => 'up',
}
Normal interface - dhcp:
network::if::dynamic { 'eth3':
ensure => 'up',
macaddress => 'fe:fe:fe:ae:ae:ae',
mtu => '1500',
ethtool_opts => 'speed 100 duplex full autoneg off',
}
Normal interface - bootp (minimal):
network::if::dynamic { 'eth2':
ensure => 'up',
macaddress => 'fe:fe:fe:fe:fe:fe',
bootproto => 'bootp',
}
Aliased interface:
network::alias { 'eth0:1':
ensure => 'up',
ipaddress => '1.2.3.5',
netmask => '255.255.255.0',
}
Aliased interface (range):
network::alias::range { 'eth1':
ensure => 'up',
ipaddress_start => '1.2.3.5',
ipaddress_end => '1.2.3.20',
clonenum_start => '0',
noaliasrouting => true,
}
Bonded master interface - static:
network::bond::static { 'bond0':
ensure => 'up',
ipaddress => '1.2.3.5',
netmask => '255.255.255.0',
gateway => '1.2.3.1',
mtu => '9000',
bonding_opts => 'mode=active-backup miimon=100',
}
Bonded master interface - dhcp:
network::bond::dynamic { 'bond2':
ensure => 'up',
mtu => '8000',
bonding_opts => 'mode=active-backup arp_interval=60 arp_ip_target=192.168.1.254',
}
Bonded slave interface:
network::bond::slave { 'eth1':
macaddress => $macaddress_eth1,
ethtool_opts => 'speed 1000 duplex full autoneg off',
master => 'bond0',
}
Static interface routes:
network::route { 'eth0':
address => [ '192.168.2.0', '10.0.0.0', ],
netmask => [ '255.255.255.0', '255.0.0.0', ],
gateway => [ '192.168.1.1', '10.0.0.1', ],
}
- Runs under Puppet 2.6 and later.
- Only works with RedHat-ish systems.
- Read /usr/share/doc/initscripts-*/sysconfig.txt for underlying details.
- Read /usr/share/doc/kernel-doc-*/Documentation/networking/bonding.txt for underlying details.
- Read /etc/sysconfig/network-scripts/ifup-aliases for underlying details.
- Only tested on CentOS 5.5 and CentOS 6.3.
- There is an assumption that an aliased interface will never use DHCP.
- bootp support is unknown for bonded interfaces. Thus no bootp bond support in this module.
- It is assumed that if you create a bond that you also create the slave interface(s).
- It is assumed that if you create an alias that you also create the parent interface.
- There is currently no IPv6 support in this module.
- network::route requires the referenced device to also be defined via network::if or network::bond.
- Setting ETHTOOL_OPTS, MTU, or BONDING_OPTS and then unsetting will not revert the running config to defaults.
- Changes to any configuration will result in "service network restart". This could cause network inaccessability for the host if the network configuration is incorrect.
- Modifying or creating a slave interface after the master has been created will not change the running config.
- There is presently no support for removing an interface.
- Support /etc/sysconfig/network-scripts/rule-<interface-name>
- Support IPv6.
- Support for more than Ethernet links.
- Support for bridge interfaces.
- Testing of VLAN support (it should Just Work(TM)).
See TODO.md for more items.
The define network::global will be replaced by a paramterized class in version 3.0.0 of this module. Please be aware that your manifests may need to change to account for the new syntax.
This:
network::global { 'default':
# blah
}
would become this:
class { 'network::global':
# blah
}
The define network::if::alias and network::bond::alias will be merged into network::alias in version 3.0.0 of this module. Please be aware that your manifests may need to change to account for the new syntax.
This:
network::if::alias { 'eth0:1':
# blah
}
would become this:
network::alias { 'eth0:1':
# blah
}
The define network::route will have parameter address renamed to ipaddress in version 3.0.0 of this module. This is for the purpose of consistency with all the other defines in the network class. Please be aware that your manifests may need to change to account for the new syntax.
This:
network::route { 'eth0':
address => '192.168.17.0',
# blah
}
would become this:
network::route { 'eth0':
ipaddress => '192.168.17.0',
# blah
}
