NetworkManager.conf: NetworkManager Reference Manual (original) (raw)

802-1x.auth-timeout

cdma.mtu

connection.auth-retries

If left unspecified, the default value is 3 tries before failing the connection.

connection.autoconnect-ports

connection.autoconnect-slaves

This is deprecated, please use "connection.autoconnect-ports" instead.

connection.down-on-poweroff

Whether the connection will be brought down before the system is powered off.

connection.ip-ping-addresses-require-all

Whether it is sufficient for any ping check to succeed among the list of target addresses, or if all ping checks must succeed for the entire list of target addresses.

connection.mud-url

If unspecified, MUD URL defaults to "none".

connection.lldp

connection.llmnr

If unspecified, the ultimate default values depends on the DNS plugin. With systemd-resolved the default currently is "yes" (2) and for all other plugins "no" (0).

connection.mdns

Currently only the systemd-resolve DNS plugin supports this setting. If the setting is unspecified both in the profile and in the global default here, then the default is determined by systemd-resolved. See MulticastDNS= inresolved.conf(5).

connection.mptcp-flags

If unspecified, the fallback is 0x22 ("enabled,subflow"). Note that if sysctl /proc/sys/net/mptcp/enabled is disabled, NetworkManager will still not configure endpoints.

connection.dns-over-tls

If unspecified, the ultimate default values depends on the DNS plugin. With systemd-resolved the default currently is global setting and for all other plugins "no" (0).

connection.stable-id

ethernet.cloned-mac-address

If left unspecified, it defaults to "preserve".

ethernet.generate-mac-address-mask

ethernet.mtu

If configured explicitly to 0, the MTU is not reconfigured during device activation unless it is required due to IPv6 constraints. If left unspecified, a DHCP/IPv6 SLAAC provided value is used or the MTU is not reconfigured during activation.

ethernet.wake-on-lan

gsm.mtu

hostname.from-dhcp

hostname.from-dns-lookup

hostname.only-from-default

hostname.priority

infiniband.mtu

ip-tunnel.mtu

ipv4.routed-dns

ipv4.dad-timeout

ipv4.dhcp-client-id

ipv4.dhcp-dscp

ipv4.dhcp-iaid

If left unspecified, it defaults to "ifname".

ipv4.dhcp-ipv6-only-preferred

If left unspecified, the "IPv6-only preferred" DHCPv4 option is disabled.

ipv4.dhcp-hostname-flags

If left unspecified, the value 3 (fqdn-encoded,fqdn-serv-update) is used.

ipv4.dhcp-send-hostname

Whether a hostname is sent to the DHCP server when acquiring a lease. When the property is not specified in the connection, the global value from NetworkManager configuration is looked up. If the global value is not set, the value from ipv4.dhcp-send-hostname-deprecated, which defaults to true, is used for backwards compatibility. In the future this will change and, in absence of a global default, it will always fallback to true.

ipv4.dhcp-send-release

Whether the DHCP client will send RELEASE message when bringing the connection down.

ipv4.dhcp-timeout

If left unspecified, the default value for the interface type is used.

ipv4.dhcp-vendor-class-identifier

If left unspecified, the default is to not send the DHCP option to the server.

ipv4.dns-priority

If unspecified or zero, use 50 for VPN profiles and 100 for other profiles.

ipv4.required-timeout

ipv4.link-local

If left unspecified, fallback to "auto" which makes it dependent on "ipv4.method" setting.

ipv4.route-metric

ipv4.route-table

If left unspecified, routes are only added to the main table. Note that this is different from explicitly selecting the main table 254, because of how NetworkManager removes extraneous routes from the tables.

ipv6.routed-dns

ipv6.addr-gen-mode

If the per-profile setting is either "default" or "default-or-eui64", the global default is used. If the default is unspecified, the fallback value is either "stable-privacy" or "eui64", depending on whether the per-profile setting is "default" or "default-or-eui64, respectively.

ipv6.ra-timeout

If left unspecified, the default value depends on the sysctl solicitation settings.

ipv6.dhcp-duid

If left unspecified, it defaults to "lease".

ipv6.dhcp-iaid

If left unspecified, it defaults to "ifname".

ipv6.dhcp-hostname-flags

If left unspecified, the value 1 (fqdn-serv-update) is used.

ipv6.dhcp-send-hostname

Whether a hostname is sent to the DHCP server when acquiring a lease. When the property is not specified in the connection, the global value from NetworkManager configuration is looked up. If the global value is not set, the value from ipv6.dhcp-send-hostname-deprecated, which defaults to true, is used for backwards compatibility. In the future this will change and, in absence of a global default, it will always fallback to true.

ipv6.dhcp-send-release

Whether the DHCP client will send RELEASE message when bringing the connection down.

ipv6.dhcp-timeout

If left unspecified, the default value for the interface type is used.

ipv6.dns-priority

If unspecified or zero, use 50 for VPN profiles and 100 for other profiles.

ipv6.ip6-privacy

If ipv6.ip6-privacy is unset, use the content of "/proc/sys/net/ipv6/conf/default/use_tempaddr" as last fallback.

ipv6.temp-valid-lifetime

If ipv6.temp-valid-lifetime is unset, use the content of "/proc/sys/net/ipv6/conf/default/temp_valid_lft" as last fallback.

ipv6.temp-preferred-lifetime

If ipv6.temp-preferred-lifetime is unset, use the content of "/proc/sys/net/ipv6/conf/default/temp_prefered_lft" as last fallback.

ipv6.required-timeout

ipv6.route-metric

ipv6.route-table

loopback.mtu

macsec.offload

sriov.autoprobe-drivers

If left unspecified, drivers are autoprobed when the SR-IOV VF gets created.

vpn.timeout

If left unspecified, default value of 60 seconds is used.

wifi.ap-isolation

If left unspecified, AP isolation is disabled.

wifi.cloned-mac-address

If left unspecified, it defaults to "preserve".

wifi.generate-mac-address-mask

wifi.mac-address-randomization

If left unspecified, MAC address randomization is disabled. This setting is deprecated for wifi.cloned-mac-address.

wifi.mtu

wifi.powersave

If left unspecified, the default value "ignore" will be used.

wifi-sec.pmf

If left unspecified, the default value "optional" will be used.

wifi-sec.fils

If left unspecified, the default value "optional" will be used.
