# Reload NetworkManager's configuration

這裡的用法，使用情境，可以用在「#5 回覆: 關於「resolvconf」的操作使用」的「實驗二」。

================================================================================

執行

$ man NetworkManager


可以找到下面這一段說明

SIGNALS
       NetworkManager process handles the following signals:

       SIGHUP
           The signal causes a reload of NetworkManager's configuration. Note that not all configuration parameters can be changed at
           runtime and therefore some changes may be applied only after the next restart of the daemon. A SIGHUP also involves further
           reloading actions, like doing a DNS update and restarting the DNS plugin. The latter can be useful for example when using the
           dnsmasq plugin and changing its configuration in /etc/NetworkManager/dnsmasq.d. However, it also means this will shortly
           interrupt name resolution. In the future, there may be further actions added. A SIGHUP means to update NetworkManager
           configuration and reload everything that is supported. Note that this does not reload connections from disk. For that there is a
           D-Bus API and nmcli's reload action

執行

$ cat /lib/systemd/system/network-manager.service | grep ExecReload

或是執行

$ cat /lib/systemd/system/NetworkManager.service | grep ExecReload

顯示

#ExecReload=/usr/bin/dbus-send --print-reply --system --type=method_call --dest=org.freedesktop.NetworkManager /org/freedesktop/NetworkManager org.freedesktop.NetworkManager.Reload uint32:0
ExecReload=/bin/kill -HUP $MAINPID

================================================================================

## 方式一

先執行下面指令，找到「NetworkManager」的「pid」

$ ps aux | grep NetworkManager

顯示

root 1121 0.0 0.2 452280 16004 ? Ssl 15:07 0:00 /usr/sbin/NetworkManager --no-daemon
...略...

執行下面指令，重新載入「NetworkManager」的「configuration」

$ sudo kill -1 1121

或是執行下面指令，重新載入「NetworkManager」的「configuration」

$ sudo kill -HUP 1121

最後執行

$ sudo /etc/init.d/network-manager status

可以看到類似如下面的訊息

...略...
Oct 04 16:46:39 my-host-name NetworkManager[1121]: <info> [1507106799.0357] reload configuration (signal Hangup)...
Oct 04 16:46:39 my-host-name NetworkManager[1121]: <info> [1507106799.0362] config: signal SIGHUP (no changes from disk)
Oct 04 16:46:39 my-host-name NetworkManager[1121]: <info> [1507106799.0362] dns-mgr: Writing DNS information to /sbin/resolvconf
...略...

也可以在「/var/log/syslog」這個檔案，看到類似的「log」。

例如執行

$ tail /var/log/syslog -n 20

可以看到類似如下面的訊息

...略...
Oct 4 16:46:39 my-host-name NetworkManager[1121]: <info> [1507106799.0357] reload configuration (signal Hangup)...
Oct 4 16:46:39 my-host-name NetworkManager[1121]: <info> [1507106799.0362] config: signal SIGHUP (no changes from disk)
Oct 4 16:46:39 my-host-name NetworkManager[1121]: <info> [1507106799.0362] dns-mgr: Writing DNS information to /sbin/resolvconf
...略...

================================================================================

## 方式二

執行下面指令，重新載入「NetworkManager」的「configuration」

$ sudo /etc/init.d/network-manager force-reload

顯示

[ ok ] Reloading network-manager configuration (via systemctl): network-manager.service.

接著執行

$ sudo /etc/init.d/network-manager status

可以看到類似如下面的訊息

...略...
Oct 04 16:54:28 my-host-name systemd[1]: Reloading Network Manager.
Oct 04 16:54:28 my-host-name NetworkManager[1121]: <info> [1507107268.7520] reload configuration (signal Hangup)...
Oct 04 16:54:28 my-host-name NetworkManager[1121]: <info> [1507107268.7524] config: signal SIGHUP (no changes from disk)

Oct 04 16:54:28 my-host-name systemd[1]: Reloaded Network Manager.
...略...

================================================================================

## 方式三

執行下面指令，重新載入「NetworkManager」的「configuration」

$ sudo dbus-send --print-reply --system --type=method_call --dest=org.freedesktop.NetworkManager /org/freedesktop/NetworkManager org.freedesktop.NetworkManager.Reload uint32:0

顯示

method return time=1507107719.119897 sender=:1.142 -> destination=:1.152 serial=288 reply_serial=2

或是執行下面指令，重新載入「NetworkManager」的「configuration」

$ sudo qdbus --system org.freedesktop.NetworkManager /org/freedesktop/NetworkManager org.freedesktop.NetworkManager.Reload 0

或是執行下面指令，重新載入「NetworkManager」的「configuration」

$ sudo gdbus call --system --dest org.freedesktop.NetworkManager --object-path /org/freedesktop/NetworkManager --method org.freedesktop.NetworkManager.Reload 0

最後執行

$ sudo /etc/init.d/network-manager status

可以看到類似如下面的訊息

...略...
Oct 04 17:01:59 my-host-name NetworkManager[1121]: <info> [1507107719.1095] audit: op="reload" arg="0" pid=10143 uid=0 result="success"

# Dispatcher scripts

================================================================================

執行

$ man NetworkManager

可以找到下面這一段敘述

DISPATCHER SCRIPTS
       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.

       Each script receives two arguments, the first being the interface name of the device an operation just happened on, and second the
       action. For device actions, the interface is the name of the kernel interface suitable for IP configuration. Thus it is either
       VPN_IP_IFACE, DEVICE_IP_IFACE, or DEVICE_IFACE, as applicable. For the hostname action it is always "none".

       The actions are:

...略...

       up
           The interface has been activated.

...略...

       down
           The interface has been deactivated.

暫告一段落

報告完畢

剛在重新檢視「network-manager」這個套件，
發現有「nmtui」可以使用，以前沒特別去注意使用它，
剛測試了一下，是在「Terminal」下的「圖形界面」工具。

執行

$ dpkg -L network-manager | grep bin | grep nmtui | sort

顯示

/usr/bin/nmtui
/usr/bin/nmtui-connect
/usr/bin/nmtui-edit
/usr/bin/nmtui-hostname

執行

$ dpkg -L network-manager | grep '/man/man.*/' | grep nmtui | sort

顯示

/usr/share/man/man1/nmtui.1.gz
/usr/share/man/man1/nmtui-connect.1.gz
/usr/share/man/man1/nmtui-edit.1.gz
/usr/share/man/man1/nmtui-hostname.1.gz

## Manpage

* $ man nmtui
* $ man nmtui-connect
* $ man nmtui-edit
* $ man nmtui-hostname

簡單的測試了一下，我的理解，「nmtui」是入口，
而「nmtui-edit」是用來維護「連線設定」，也就是「列表」，「新增」，「編輯」，「刪除」。
編輯好後，則是使用「nmtui-connect」來啟用某一個連線。
