debops.tcpwrappers default variables

Main configuration

tcpwrappers__enabled

Enable or disable configuration of tcpwrappers.

tcpwrappers__enabled: True
tcpwrappers__ansible_controllers

Optional list of CIDR hosts which will be allowed to connect to sshd service. Entries are saved in the local facts on remote hosts.

Remember to specify IP address from the remote host point of view. Format: "IP address/netmask", for example: 192.168.1.1/32.

Note: If you are using debop.ferm role too (or the DebOps playbook),

mind setting ferm__ansible_controllers. An easier way would be to use the debops.sshd role to configure ssh service.

tcpwrappers__ansible_controllers: []
tcpwrappers__deny_all

By default debops.tcpwrappers will deny all connections using /etc/hosts.deny file and only allow whitelisted connections in /etc/hosts.allow. Set this variable to False to disable that.

tcpwrappers__deny_all: True
tcpwrappers__divert_hosts_allow

Path of the diverted /etc/hosts.allow file. It will be merged with the rest of the generated configuration files using assemble ansible module. Warning: do not change this variable while the role is enabled.

tcpwrappers__divert_hosts_allow: '/etc/hosts.allow.d/05_debian_hosts.allow'
