Why nm-tool is no longer available in Ubuntu 15.04?
Please read the 2015-01-27 changelog for network manager. A snippet form all the changes ...
network-manager (0.9.10.0-1) unstable; urgency=medium
- New upstream release.
- Exclude libtool .la files from list-missing.
- Update symbols files.
- Update Build-Depends as per configure.ac.
- Build and install nmtui, a curses-based interface for easier console operation.
- Install new device plugins.
- Stop installing the nm-tool binary which was dropped upstream as it has been replaced by the much more powerful nmcli tool.
The name of what you want is nmcli.
Besides that there is a new tool call nmtui:
network-manager (0.9.10.0-1) unstable; urgency=medium
- New upstream release.
- Exclude libtool .la files from list-missing.
- Update symbols files.
- Update Build-Depends as per configure.ac.
- Build and install nmtui, a curses-based interface for easier console operation.
From the manual page for nmtui:
nmtui — Text User Interface for controlling NetworkManager
nmtui [edit | connect | hostname] [...] nmtui-edit [connection-id | connection-name] nmtui-connect [connection-name | connection-uuid | device-name | Wi-Fi-SSID] nmtui-hostname
nm-tool was used to report network manager's status and information about interfaces, providing a convenient summary of network connections and your connection status. However my understanding is that as of 15.04 Ubuntu is switching to systemd service manager, and NetworkManager from previous versions doesn't work quite well with systemd, hence now NetworkManager has changed to the one very similar to NetworkManager used in Fedora ( which by the way uses systemd ).
What you can do is to use nmcli options to give you a convenient summary of just like nm-tool use to do. In particular use nmcli device show <interface>. This is the same as nmcli dev list <iface> on the previous version. <interface> part is optional, and can be used only if you need info about specific interface, such as wlan0 or eth0.
To view info for alll interfaces, use nmcli dev show. There is a lot of material , so you can pipe it all into less like so : nmcli dev show | less
And here is a little one-liner I wrote to give general overview of system connections: nmcli dev show | awk '/GENERAL.DEVICE/,/GENERAL.DRIVER/;/GENERAL.CONNECTION/;/IP4.ADDRESS/,/IP4.DOMAIN/'
Sample output:
GENERAL.DEVICE: eth0
GENERAL.TYPE: 802-3-ethernet
GENERAL.VENDOR: Realtek Semiconductor Co., Ltd.
GENERAL.PRODUCT: RTL8101E/RTL8102E PCI Express Fast Ethernet controller
GENERAL.DRIVER: r8169
GENERAL.CONNECTION: not connected
GENERAL.DEVICE: wlan0
GENERAL.TYPE: 802-11-wireless
GENERAL.VENDOR: Realtek Semiconductor Co., Ltd.
GENERAL.PRODUCT: RTL8187SE Wireless LAN Controller
GENERAL.DRIVER: r8180
GENERAL.CONNECTION: /org/freedesktop/NetworkManager/ActiveConnection/0
IP4.ADDRESS[1]: ip = ******/24, gw = ******.1
IP4.DNS[1]: 208.67.222.222
IP4.DNS[2]: 208.67.220.220
IP4.DNS[3]: 8.8.8.8
IP4.DOMAIN[1]: ******.edu
nmcli dev wifi will list available access points. Note, that dev and device are used interchangeably.
As of recent versions, nm-tool is no longer included as part of the network-manager package.
For 15.04+:
You can, however, extract nm-tool from the 14.04 version of network-manager. Here's how it can be done.
It should be noted that there may have been security updates since posting this. You can visit http://packages.ubuntu.com/trusty/network-manager to verify the version listed below is the most recent version available.
Run the following commands:
cd
mkdir nm-tool; cd nm-tool
wget http://security.ubuntu.com/ubuntu/pool/main/n/network-manager/network-manager_0.9.8.8-0ubuntu7.1_amd64.deb
ar xvf *
tar xvf dat*
sudo mv ./usr/bin/nm-tool /usr/local/bin/
cd ..
rm -r nm-tool
The following commands should now be available:
nm-tool.
