Network Manager dispatcher.d
I've created a script that I'd like Network Manager to run after the network is up. I can run the script as root manually if I pass or set the $status variable and everything works, however I can't seem to get the script to run when I start NetworkManager service. Where does NetworkManager log since there is no daemon.log file in /var/log?
Following script is within /etc/NetworkManager/dispatcher.d/ with permissions of 711.
Here is the script (very similar to what was posted in Arch Wiki):
#!/bin/bash
USER='xxxx'
REMOTE='[email protected]:/home/xxxx'
LOCAL='/home/xxxx/mnt_sshfs'
OPTIONS="-o idmap=user -o follow_symlinks -C -p 22"
interface=$1 status=$2
case $status in
up)
sleep 5
#expect fwknop daemon call (Which is run as 49_fwknopcall)
su "$USER" -c "sshfs $OPTIONS $LOCAL $REMOTE"
down)
fusermount -u "$LOCAL"
esac
Thanks for tip about journalctl!! Made a big difference.
Here is what the script is telling me:
Apr 03 11:45:08 orphan nm-dispatcher.action[553]: Script '/etc/NetworkManager/dispatcher.d/50-mount_sshfs_share_gohilton_2223.sh' took too long; killing it.
I'm guessing the ssh part where it attempts to connect to the remote server and mount the remote ssh is taking to long however even using journalctl in verbose mode really doesn't confirm this assumption.

[SOLVED]Network Manager dispatcher unexpected unmounting davfs folders
I have used Network Manager dispatcher to configure automatic mount of cloud storage using webdav. i have used davfs2 to perform mounting and wrote a script for NM dispatcher.
If i run /etc/NetworkManager/dispatcher.d/10-YandexDisk.sh manualy all works perfect.
If this script will be executed by NM-dispatcher all will fine(YandexDisk mounts successfully, sycronization - successfully), but after ~10 seconds mount.davfs gets signal 15.

Last edited by pirat9600q (2013-08-02 08:14:44)I solved the problem. Here is a little explanation.
After NetworkManager establishes network connection, NetworkManager-dispatcher service is started( for ~10 seconds). This service execute /usr/lib/networkmanager/nm-dispatcher.action, which execute scripts in /etc/NetworkManager/dispatcher.d. After exiting nm-dispatcher.action mount.davfs process appears in NetworkManager-dispatcher`s CGroup. By default all processes in CGroup must be killed when service stops. To change this behavior I have added KillMode=process to [Service] section of NetworkManager-dispatcher.service file.

Network Manager Dispatcher with NFS/Autofs
I'm looking to see what is the most recommended method of starting automounted nfs shares after network manager has brought up a wireless connection.
Currently, I'm using the network manager dispatcher and I have dispatch files for:
netfs
autofs
In rc.conf DAEMONS I still have
rpcbind
nfs-common
Should I make dispatcher files for rpcbind and nfs-common as well? What do people around here consider the proper way to do this?Thanks for tip about journalctl!! Made a big difference.
Here is what the script is telling me:
Apr 03 11:45:08 orphan nm-dispatcher.action[553]: Script '/etc/NetworkManager/dispatcher.d/50-mount_sshfs_share_gohilton_2223.sh' took too long; killing it.
I'm guessing the ssh part where it attempts to connect to the remote server and mount the remote ssh is taking to long however even using journalctl in verbose mode really doesn't confirm this assumption.
I'm wondering if this would best be done with systemd unit files? -
Network Manager Dispatcher returns error code 1 on tested scripts
I'm trying to write a simple script to test the network manager dispatcher but while it's working when I manually launch the script, the nm dispatcher print "nm-dispatcher.action: Script '/etc/NetworkManager/dispatcher.d/start_dropbox.sh' exited with error status 1" into the logs.
#!/bin/sh
IF=$1
STATUS=$2
/bin/su USERNAME -c "/usr/bin/notify-send lol woot"
exit $?
I tried using absolute paths, just the commands, running with sudo(although the scripts should be run as root) and without su. I tested the script as root and as a simple user using a terminal and it works just fine every time.
echo seems to work fine as I don't get any errors in the logs, but that way I can't see what's inside $1 and $2 when the dispatcher calls the script and I can't think of any way to debug the script which doesn't involve notify-send.
I'm sure I'm missing something very simple here, but I can't see it myself and searching google and the arch forums hasn't helped me any.I solved the problem. Here is a little explanation.

Network Manager Dispatcher???
Can someone point me to a document that explains just how the hell to set this up....the wiki is very vague and confusing. I find some posts here saying to load networkmanager-dispatcher in the DAEMONS in rc.conf...but t.hat just causes an error message to the effect of "can't find this daemon" when I boot up... Please help. I'm trying to get my cifs mounts in fstab to mount up AFTER the network is connected. Thanks

How to create a persistent network manager profile with openvpn?
After installing networkmanager and openvpn everything works fine except that the networkmanager profile is not persistent and nm creates and selects a new profile with every boot. I followed Persistent configuration on boot using systemd which creates a persistent profile and cuts out the creation of a new profile, but when I build a openvpn connection it won't change the i.p. any longer. I've been searching for a week, read and learned a lot, but without a solution.
My main question is what's creating and selecting a new network profile after booting? I've 2 fresh installations of Arch and Archbang on 2 pc's and with both the same issue/problem.

Network Manager driving me crazy (3 issues)
Hey guys I'm new here, hope you can help me
nm-applet is driving me crazy!
First issue: when I boot nm-applet doesn't appear in my tint2 eventhough I'm connected. This don't appear all the time, it's random. I have to kill it and restart it to be able to see it.
I use openbox and I have this in .config/openbox/autostart
(sleep 3 && /usr/bin/nm-applet --sm-disable) &
Second issue:
I selected the save option for the password of my vpn but it won't save it... Or wait, yes it will.. But not all the time. It asks me for the pass sometimes, and sometimes not
Third issue:
I thicked the "automatically connect to vpn for this connection" but guess what... It won't
Any idea about how to troubleshot this. I'm seriously considering pacman -R network-manager and pacman -S something else
Thank you
Last edited by Truc (2014-03-06 21:17:51)1st issue: run nm-applet from the command line (take it out of openbox's start file wherever that is) after you log in to see what's going on.
2nd issue: do you have gnome-keyring installed? I believe it should be started with by networkmanager when it's needed, but you may need to figure out how to start it on your own. I don't know how.
3rd issue: I believe the automatic connection to vpn on a specific network is triggered by networkmanager-dispatcher which is just part of the networkmanager package, but is its own separate service. When you enable/start NetworkManager via systemctl, it should enable/start 3 services - the dispatcher is one of them. Do you have that running?
I may be wrong about some of this; it's been a while since i've used NetworkManager. -

Can anyone offer some suggestion on how to get network manager going, I would like to use it. In the past
I have used Wicd, but it has some limitations.
Cheers,

Ok, I found the issue. I was missing the firmware for the card. I downloaded firmware from the intel site as per the wiki on wireless and
my interface comes up (shown with ifconfig) and I can see all the networks.
However, I cannot seem to connect to my network with WPA. When I go to connect I get network manager thinking the access point is WEP and asking for pass phrase.
If I select WPA(personal) and fill in a password, nothing happens .... just says unavailable.
Can anyone give some idea's here. I have not used network manager before for WPA.
Cheers,

I use WPA2 with network manager without a problem. It should "just work", im not sure why you have issues, can you switch your router to a different security protocol to test? -
How do I install individual driver of Killer LAN without its Network Management application?
I found sometimes the Network Management application would conflict with other online application, and in other forum an user provided a pure driver package that can solve the problem.
Here is the steps:
First you can download MSI pure Killer LAN driver from this link:
http://pan.baidu.com/s/1mgwZs96
Please uninstall old Killer LAN driver package from control panel if you already have the driver in OS.
Download and extract the RAR file to windows desktop. Double click “dpinst.exe” to install the killer driver.
It is normal if you see the message of “No device for update present” in the last step, that’ s because the driver package includes all kinds of killer LAN chip drivers, some don’t exist in your system.
Just click “Finish” to complete the driver installation. Restart system and you can start to enjoy the web surfing.
And if you encounter problem when you uninstall Killer LAN driver, you can use Killer official uninstall utility to completely remove the driver.
32 bit:
https://www.qca.qualcomm.com/drivers/KillerCleaner_32bit.exe
64 bit:
https://www.qca.qualcomm.com/drivers/KillerCleaner_64bit.exeJust install the Killer LAN driver from MSI website, the manager is always installed with the driver.

Mock RFP for SUN network management tool, desperate 4 help, just need specs
OK, I have a project that in essence is a mock Request for Proposal (RFP), I play as an intern, & our instructor roleplays the manager we need to convince. The different network management tools that were available were for example; HP Openview, Cisco Works, Sniffer....& I of course chose SunNet. We need to gather information on the tool, then turn around & design a relatively simple network from the specs that were given, & finally discuss how the management tool's abilities could benefit the (mock) company...power point presentation & all.
Here it is from the homework sheet given to us...."These products will need to be useful in a 5000 node network that has four main locations that are primarily Ethernet. There is a legacy 100 nodes of Token Ring attached to a mainframe. Cisco or Foundry routers connect the Four main locations, with swiches employed. Other connections to these sites are done via DSL or ISDN. Additional considerations are wireless communications, VOIP & Content delivery systems.
I know this is a lot & I'm not asking for someone to do all this for me, just simply provide any information you know about Enterprise management tools 2.0 or 3.0,or anything you may feel better suits my needs, as the links I have surfed about them give little to nothing about specifics that I need to make any argument. If you have any links send them...if you have anyting in hard copy I will pay for postage... I need to get this done & have little time as I go to school & work full time at Motorola (but only as a contractor), so I'm starting to choke & need help....any u can give is so very appreciated....& sorry to make this request a publishable novel here on the board, but thats what it is. Thanks again......MarkA good solution. Liked it very much. Can you please make it a technet blog for others.

ORACLE NETWORK MANAGER 기본적인 사용방법
제품 : SQL*NET
작성날짜 : 2002-04-12
ORACLE NETWORK MANAGER 기본적인 사용방법
========================================
I. TERMINOLOGY TO KNOW BEFORE USING THIS GUIDE
A. community - a set of nodes that use the same network protocol.
B. listener - a service that waits for incoming requests from client
and server nodes.
C. system identifier - (SID) name of the Oracle database instance,
which is usually the same as the database name
II. NETWORK CONFIGURATION STEPS
A. Develop a pictorial representation of the network.
B. Provide configuration data to Network Manager.
C. Save the network configuration data and generate the configuration files.
Step A. Develop a pictorial representation of the network.
The sample network is a single protocol TCP/IP network with two
databases. Each node has one listener.
Step B. Provide configuration data to Network Manager.
Network Manager requires information about the objects in the
network before it creates the configuration files. There is an
on-line walk-through which leads you through the creation of a
network definition from the beginning (specification of definitions)
to the end (generation of the configuration files). The walk-through
provides information in pop-up boxes before each step. During the
walk through, a series of object property sheets, which gather the
data about network objects, appear with values which you may need
to alter.
** Tasks **
1. Launch Network Manager and click OK to store the network definition
in a file. In the Open window click Cancel.
2. Choose New from the File pull-down menu to start a new network
definition. Use the on-line walk through and click OK in the Network
Description dialog box.
3. In the Community property sheet, enter TCP as the name of the
community and choose TCP/IP from the protocol list box. Close the
community property sheet by clicking OK.
4. a. To define a node, enter the node name, TCP_node1, in the Node
property sheet.
b. Specify UNIX as the type of operating system in the drop-down
list.
c. Click on the community folder tab. Add TCP.WORLD to the node
community list (Note:WORLD is a default suffix) and close the
node property sheet by clicking OK.
5. Click OK to close the Node property sheet. To create the node,
TCP_node2, repeat step 4 and specify the type to be OS/2.
6. Create a listener in the Listener property sheet, by entering
TCP_listener1 as the name and choosing TCP_node1 in the node
pull-down menu to indicate what node TCP_listener1 will listen to.
Select the addresses folder tab and click Create. This defines the
address of the listener. A service address property sheet appears
with the address information as default values. Click OK.
7. Click the database folder tab to define a database for the listener.
In the Database property sheet, click Create to specify information
about the Oracle database that will be included in the network.
Enter TCP_DB1 as the name of the database. Click TCP_node1 as the
node. Enter the SID: db1. In the Operating System Specific Details
field, enter the directory path of the Oracle executables, i.e.
/usr/oracle for Unix or c:\oraos2\ for OS/2. Click OK to close the
Database property sheet.
8. Click OK to close the listener property sheet. To create
TCP_listener2, repeat steps 6-7 and substitute TCP_node2, TCP_DB2,
and db2 for the node, database, and SID, respectively.
Note: The on-line walk-through automatically validates the network configuration.
Step C. Save the network configuration data and generate configuration files.
1. Save the network definition.
2. Click File System in the Export Network Definition dialog box and
click OK. Choose the directory and click OK. The network definition
is now complete and the configuration files are generated.
III. OTHER INFORMATION
A. About the configuration files
If the network definition is saved to the file system,
Network Manager creates two types of subdirectories within the
directory chosen to store the network definition.
These are: a node specific directory, which has the same name as the
node and contact configuration files for the service the node provides,
and a client profile directory, which has the same name as the client
community and contains configuration files for each client.
B. Hardware and Software Requirements
PC with 6Mb disk, IBM or 100% compatible with an 80386 processor
or higher one CD-ROM drive
MS-DOS Version 5.0 or later and Windows 3.1Hi Steve,
1) PL/SQL API for Network Analysis is coming in Oracle 10g Release 2.
2) In Oracle 10g Release 1 it is a requirement to load the entire network. Loading the entire street network of new york city on my 1 Ghz laptop requires about 1 minute. In Oracle 10g Release 2 you can specify a predicate on the load network so you do not have to load the entire network.
3) Source code for elocation will be available as an Oracle 10g Release 2 feature (I'm not sure what the "name" of the feature is, but it is a bundling of geocoding and routing, and when combined with MapViewer is a complete "elocation in a box" type of feature.
Hope this helps. -
Trying to use wireless N with iwlwifi & network manager
Have all the h/w necessary to use wireless N:
Intel Centrino-N 1030
Linksys E3200 running Tomato 1.28
Linksys E4200 running dd-wrt 21286
Also updated everything today (pacman -Syu):
>uname -a
Linux hostname 3.12.9-2-ARCH #1 SMP PREEMPT Fri Jan 31 10:22:54 CET 2014 x86_64 GNU/Linux
So, with either router set up with as an AP at 2.4GHz and N-Only (the centrino 1030 doesn't support 5GHz), and the module defaults loaded, I see odd behavior. First, once connected to either AP, Network Manager still reports the connection to be at B/G.
I checked the module config, and this part is relevant:
>modinfo iwlwifi | grep 11n
parm: 11n_disable:disable 11n functionality, bitmap: 1: full, 2: agg TX, 4: agg RX (uint)
There's a lot of chatter on the forums about earlier kernels not supporting N w/ iwlwifi, and recommending to disable it with '11n_disable=1' in /etc/modprobe.d/iwlwifi.conf. So I tried explicitly enabling it, and assuming it's a binary value:
>cat /etc/modprobe.d/iwlwifi.conf
options iwlwifi 11n_disable=0
After reloading the module(s) (and restarting wpa_supplicant & networkmanager), the thing I'm finding confusing is that I can see evidence of this change take effect:
>cat /sys/module/iwlwifi/parameters/11n_disable
0
...but it doesn't affect the output of modinfo (same as above), nor am I able to connect to either router at N (NM still reports B/G). Also confused how it connects at all when the routers are set to N-Only?modinfo iwlwifi
That is not supposed to change. It just shows you the parameters and their valid configurations.
options iwlwifi 11n_disable=0
>cat /sys/module/iwlwifi/parameters/11n_disable
0
Did you check that it was not already 0?
...but it doesn't affect the output of modinfo (same as above), nor am I able to connect to either router at N (NM still reports B/G). Also confused how it connects at all when the routers are set to N-Only?
If the card connects with the routers set to n only, then the card is capable of working with n. I usually check with nm-tools and look at the speed indicated.
Here is the thing: Routers and cards sometimes negotiate a lower speed to prevent intereference with other devices. I usually 'get' N-speed only once I start to saturate the link. -
Oracle BPM for Network Management Projects
Has anybody used Oracle BPM for network management projects with millions of events?
Can Oracle BPM handle it?Please follow this step may this solve your problem.
please modify any thing in process "ExpenseReporting" for example any transition or any activity to place some where else or any other modification and then save that process. Then clean the project and build and deploy it.
if this also not solve the problem then export that project to and import it again in your workspace (Create new workspace or change the project name in same workspace ) and then again clean, build and deploy the application then test in work space.
Thanks,

Hi Everybody
I just tried to play a little with gnome-network-manager from AUR, first of all the normal network manager was missing a few files, but I managed to find them(http://aur.archlinux.org/packages/networkmanager/networkmanager/).
But when i start up gnome, it is shown fine in the Status Area, and shows all the networks, but it won't connect to any...
When connecting to an unencrypted network it says it is waiting for the network, when connecting to an encrypted network, it is waiting for the key to be verified.
My assumption is, that it is waiting for DHCP, in both cases.
If I use wifi-radar it gets an IP perfectly, also if I use dhclient or dhpcd it works fine.
Any suggestions?I tried to use the one from testing, along with the gnome GUI from testing, but with no luck...
As you can see here, it tells me it is waiting fr the key, http://gallery.timmy.dk/Screenshots/gno … anager.png
But in the consle, iwconfig says I'm already connected...
So I'm pretty sure there something wrong with the dhcp
