Bug #15143
Updated by Dominic Cleal almost 8 years ago
since version 1.11.x the :subnet: definition in foreman-proxy dhcp settings is no longer optional. Below config was migrated during one of the earlier updates: <pre> ~]# cat /etc/foreman-proxy/settings.d/dhcp.yml --- :enabled: https :use_provider: dhcp_isc Default config from package: --- # Can be true, false, or http/https to enable just one of the protocols :enabled: false # valid providers: # - dhcp_isc (ISC dhcp server) # - dhcp_native_ms (Microsoft native implementation) # - dhcp_virsh (simple implementation for libvirt) #:use_provider: dhcp_isc #:server: 127.0.0.1 # subnets restricts the subnets queried to a subset, to reduce the query time. #:subnets: [192.168.205.0/255.255.255.128, 192.168.205.128/255.255.255.128] ~]# grep -i debug /etc/foreman-proxy/settings.yml # WARN, DEBUG, ERROR, FATAL, INFO, UNKNOWN :log_level: DEBUG Restart foreman-proxy: D, [2016-05-23T16:13:23.489289 #3599] DEBUG -- : Rack::Handler::WEBrick is mounted on /.
