NetworkManager will connect any network device when a connection for that device becomes available, unless that behavior is disabled\&. Information about networking is exported via a D\-Bus interface to any interested application, providing a rich API with which to inspect and control network settings and operation\&. +.SH "DISPATCHER SCRIPTS" +.PP +NetworkManager will execute scripts in the /etc/NetworkManager/dispatcher\&.d directory or subdirectories in alphabetical order in response to network events\&. Each script should be a regular executable file owned by root\&. Furthermore, it must not be writable by group or other, and not setuid\&. +.PP +Each script receives two arguments, the first being the interface name of the device an operation just happened on, and second the action\&. +.PP +The actions are: +.PP +\fIpre\-up\fR +.RS 4 +The interface is connected to the network but is not yet fully activated\&. Scripts acting on this event must be placed or symlinked into the /etc/NetworkManager/dispatcher\&.d/pre\-up\&.d directory, and NetworkManager will wait for script execution to complete before indicating to applications that the interface is fully activated\&. +.RE +.PP +\fIup\fR +.RS 4 +The interface has been activated\&. +.RE +.PP +\fIpre\-down\fR +.RS 4 +The interface will be deactivated but has not yet been disconnected from the network\&. Scripts acting on this event must be placed or symlinked into the /etc/NetworkManager/dispatcher\&.d/pre\-down\&.d directory, and NetworkManager will wait for script execution to complete before disconnecting the interface from its network\&. Note that this event is not emitted for forced disconnections, like when carrier is lost or a wireless signal fades\&. It is only emitted when there is an opportunity to cleanly handle a network disconnection event\&. +.RE +.PP +\fIdown\fR +.RS 4 +The interface has been deactivated\&. +.RE +.PP +\fIvpn\-pre\-up\fR +.RS 4 +The VPN is connected to the network but is not yet fully activated\&. Scripts acting on this event must be placed or symlinked into the /etc/NetworkManager/dispatcher\&.d/pre\-up\&.d directory, and NetworkManager will wait for script execution to complete before indicating to applications that the VPN is fully activated\&. +.RE +.PP +\fIvpn\-up\fR +.RS 4 +A VPN connection has been activated\&. +.RE +.PP +\fIvpn\-pre\-down\fR +.RS 4 +The VPN will be deactivated but has not yet been disconnected from the network\&. Scripts acting on this event must be placed or symlinked into the /etc/NetworkManager/dispatcher\&.d/pre\-down\&.d directory, and NetworkManager will wait for script execution to complete before disconnecting the VPN from its network\&. Note that this event is not emitted for forced disconnections, like when the VPN terminates unexpectedly or general connectivity is lost\&. It is only emitted when there is an opportunity to cleanly handle a VPN disconnection event\&. +.RE +.PP +\fIvpn\-down\fR +.RS 4 +A VPN connection has been deactivated\&. +.RE +.PP +\fIhostname\fR +.RS 4 +The system hostname has been updated\&. Use gethostname(2) to retrieve it\&. The interface name (first argument) is empty and no environment variable is set for this action\&. +.RE +.PP +\fIdhcp4\-change\fR +.RS 4 +The DHCPv4 lease has changed (renewed, rebound, etc)\&. +.RE +.PP +\fIdhcp6\-change\fR +.RS 4 +The DHCPv6 lease has changed (renewed, rebound, etc)\&. +.RE +.PP +The environment contains more information about the interface and the connection\&. The following variables are available for the use in the dispatcher scripts: +.PP +\fICONNECTION_UUID\fR +.RS 4 +The UUID of the connection profile\&. +.RE +.PP +\fICONNECTION_ID\fR +.RS 4 +The name (ID) of the connection profile\&. +.RE +.PP +\fIDEVICE_IFACE\fR +.RS 4 +The interface name of the device\&. +.RE +.PP +\fIDEVICE_IP_IFACE\fR +.RS 4 +The IP interface name of the device\&. +.RE +.PP +\fIIP4_ADDRESS_N\fR +.RS 4 +The IPv4 address in the format "address/prefix gateway", where N is a number from 0 to (# IPv4 address \e\- 1)\&. +.RE +.PP +\fIIP4_NUM_ADDRESSES\fR +.RS 4 +The variable contains the number of IPv4 addresses the script may expect\&. +.RE +.PP +\fIIP4_ROUTE_N\fR +.RS 4 +The IPv4 route in the format "address/prefix next\-hop metric", where N is a number from 0 to (# IPv4 routes \e\- 1)\&. +.RE +.PP +\fIIP4_NUM_ROUTES\fR +.RS 4 +The variable contains the number of IPv4 routes the script may expect\&. +.RE +.PP +\fIIP4_NAMESERVERS\fR +.RS 4 +The variable contains a space\-separated list of the DNS servers\&. +.RE +.PP +\fIIP4_DOMAINS\fR +.RS 4 +The variable contains a space\-separated list of the search domains\&. +.RE +.PP +\fIDHCP4_<dhcp\-option\-name>\fR +.RS 4 +If the connection used DHCP for address configuration, the received DHCP configuration is passed in the environment using standard DHCP option names, prefixed with "DHCP4_", like "DHCP4_HOST_NAME=foobar"\&. +.RE +.PP +\fIIP6_<name> and DHCP6_<name>\fR +.RS 4 +The same variables as for IPv4 are available for IPv6, but the prefixes are IP6_ and DHCP6_ instead\&. +.RE +.PP +In case of VPN, VPN_IP_IFACE is set, and IP4_*, IP6_* variables with VPN prefix are exported too, like VPN_IP4_ADDRESS_0, VPN_IP4_NUM_ADDRESSES\&. +.PP +Dispatcher scripts are run one at a time, but asynchronously from the main NetworkManager process, and will be killed if they run for too long\&. If your script might take arbitrarily long to complete, you should spawn a child process and have the parent return immediately\&. Also beware that once a script is queued, it will always be run, even if a later event renders it obsolete\&. (Eg, if an interface goes up, and then back down again quickly, it is possible that one or more "up" scripts will be run after the interface has gone down\&.) +.SH "OPTIONS" +.PP +The following options are understood: +.PP +\fB\-\-version\fR | \fB\-V\fR +.RS 4 +Print the NetworkManager software version and exit\&. +.RE +.PP +\fB\-\-help\fR | \fB\-h\fR +.RS 4 +Print NetworkManager\*(Aqs available options and exit\&. +.RE +.PP +\fB\-\-no\-daemon\fR | \fB\-n\fR +.RS 4 +Do not daemonize\&. +.RE +.PP +\fB\-\-debug\fR | \fB\-d\fR +.RS 4 +Do not daemonize, and direct log output to the controlling terminal in addition to syslog\&. +.RE +.PP +\fB\-\-pid\-file\fR | \fB\-p\fR +.RS 4 +Specify location of a PID file\&. The PID file is used for storing PID of the running proccess and prevents running multiple instances\&. +.RE +.PP +\fB\-\-state\-file\fR +.RS 4 +Specify file for storing state of the NetworkManager persistently\&. If not specified, the default value of /var/lib/NetworkManager/NetworkManager\&.state is used\&. +.RE +.PP +\fB\-\-config\fR +.RS 4 +Specify configuration file to set up various settings for NetworkManager\&. If not specified, the default value of /etc/NetworkManager/NetworkManager\&.conf is used with a fallback to the older \*(Aqnm\e\-system\e\-settings\&.conf\*(Aq if located in the same directory\&. See +\fBNetworkManager.conf\fR(5) +for more information on configuration file\&. +.RE +.PP +\fB\-\-plugins\fR +.RS 4 +List plugins used to manage system\-wide connection settings\&. This list has preference over plugins specified in the configuration file\&. Currently supported plugins are: keyfile, +\fBifcfg\-rh\fR, +\fBifcfg\-suse\fR, +\fBifupdown\fR\&. +.RE +.PP +\fB\-\-log\-level\fR +.RS 4 +Sets how much information NetworkManager sends to the log destination (usually syslog\*(Aqs "daemon" facility)\&. By default, only informational, warning, and error messages are logged\&. See the section on +logging +in +\fBNetworkManager.conf\fR(5) +for more information\&. +.RE +.PP +\fB\-\-log\-domains\fR +.RS 4 +A comma\-separated list specifying which operations are logged to the log destination (usually syslog)\&. By default, most domains are logging\-enabled\&. See the section on +logging +in +\fBNetworkManager.conf\fR(5) +for more information\&. +.RE +.SH "DEBUGGING" +.PP +The following environment variables are supported to help debugging\&. When used in conjunction with the +\fB\-\-no\-daemon\fR +option (thus echoing PPP and DHCP helper output to stdout) these can quickly help pinpoint the source of connection issues\&. Also see the +\fB\-\-log\-level\fR +and +\fB\-\-log\-domains\fR +to enable debug logging inside NetworkManager itself\&. +.PP +\fBNM_PPP_DEBUG\fR: When set to anything, causes NetworkManager to turn on PPP debugging in pppd, which logs all PPP and PPTP frames and client/server exchanges\&. +.SH "SEE ALSO" +.PP +\fBNetworkManager.conf\fR(5), +\fBnmcli\fR(1), +\fBnmcli-examples\fR(5), +\fBnm-online\fR(1), +\fBnm-settings\fR(5), +\fBnm-applet\fR(1), +\fBnm-connection-editor\fR(1) |
