# Example configuration snippet for NetworkManager to
|
|
# overwrite some default value for more privacy.
|
|
# Drop this file for example to /etc/NetworkManager/conf.d/30-anon.conf
|
|
#
|
|
# See man NetworkManager.conf(5) for how default values
|
|
# work. See man nm-settings(5) for the connection properties.
|
|
#
|
|
#
|
|
# This enables some privacy setting by default. The defaults
|
|
# apply only to settings that do not explicitly configure
|
|
# a per-connection override.
|
|
# That means, if the connection profile has
|
|
#
|
|
# $ nmcli -f 'connection.stable-id,802-11-wireless.cloned-mac-address,802-11-wireless.mac-address-randomization,802-3-ethernet.cloned-mac-address,ipv4.dhcp-client-id,ipv6.addr-gen-mode,ipv6.dhcp-duid,ipv6.ip6-privacy' connection show "$CON_NAME"
|
|
# connection.stable-id: --
|
|
# 802-11-wireless.cloned-mac-address: --
|
|
# 802-11-wireless.mac-address-randomization: default
|
|
# 802-3-ethernet.cloned-mac-address: --
|
|
# ipv4.dhcp-client-id: --
|
|
# ipv6.addr-gen-mode: stable-privacy
|
|
# ipv6.dhcp-duid: --
|
|
# ipv6.ip6-privacy: -1 (unknown)
|
|
#
|
|
# then the default values are inherited and thus both the MAC
|
|
# address, IPv6 host identifier, and DHCP identifiers are randomized.
|
|
# Also, ipv6 private addresses (RFC4941) are used in
|
|
# addition.
|
|
#
|
|
#
|
|
# The connection's stable-id is really a token associated with the identity
|
|
# of the connection. It means, by setting it to different values, different
|
|
# addresses and DHCP options are generated.
|
|
# For some profiles it can make sense to reuse the same stable-id
|
|
# (and thus share MAC address and IPv6 host identifier) for the duration
|
|
# of the current boot, but still exclusive to the connection profile.
|
|
# Thus, explicitly set the stable-id like:
|
|
#
|
|
# $ nmcli connection modify "$CON_NAME" connection.stable-id '${CONNECTION}/${BOOT}'
|
|
#
|
|
# ... or keep it stable across reboots, but still distinct per profile:
|
|
#
|
|
# $ nmcli connection modify "$CON_NAME" connection.stable-id '${CONNECTION}'
|
|
#
|
|
# ... or use the same stable IDs for a bunch of profiles
|
|
#
|
|
# $ nmcli connection modify "$CON_NAME" connection.stable-id 'my-home-wifi yada yada'
|
|
#
|
|
# ... or use the same IDs for a bunch of profiles, but only for the current boot
|
|
#
|
|
# $ nmcli connection modify "$CON_NAME" connection.stable-id 'my-home-wifi yada yada/${BOOT}'
