snetaid is an UNIX configuration daemon for simple-netaid, whose mission is to automatically connect the ethernet device when a cable is plugged in, or in the second place, the wireless device if some of the available active wifis has been installed in your system previously. It uses Debian’s native ifupdown program for that.
Use the APT package manager to install snetaid.
apt-get install snetaid
That done, the configuration of the daemon will be defined in /etc/simple-netaid/snetaid.conf. This file is sourced by the init script and used to start snetaid with appropriate arguments. Edit the content for configuration changes. Default values are:
pid_file=/var/run/snetaid.pid delay=10 automatically_connect=1 stop_if_connected=1
The pid file stores the process ID of the running daemon, and the standard syslog is used as the message logging so far. If you only need to see the logs generated by snetaid, you can use pipe and grep command to add display filter like this:
tail -f /var/log/syslog | grep "snetaid"
The pid file also locks the resource in order to prevent other instances of the program running, playing at the same time the role of a lock file. On the other hand, the sleep time is the delay -in seconds- between two consecutive network connection attempts when the automatically_connect option is set to 1.
You can build your own debian packages in a very easy way using
git-buildpackage (a wrapper for
All you need to do is:
$ git clone https://git.devuan.org/aitor_czr/snetaid.git $ cd snetaid
If you type
git status you can see all:
On branch master Your branch is up-to-date with 'origin/master'. nothing to commit, working directory clean
To list all the local and remote branches type:
$ git branch -a
Let’s checkout on the following branches (in this order):
$ git checkout -b pristine-tar origin/pristine-tar $ git checkout -b gbp-release_0.1 origin/gbp-release_0.1
gbp reflects those branches containing the debian folder.
Now we can build the packages:
$ gbp buildpackage
Once the packages have been generated, go to the build directory and install them:
$ cd ../build-area $ sudo dpkg -i *.deb
If you are using a different package management system, then you’ll need to build the project from source.
The current version of snetaid has been tested under Devuan Beowulf, requering:
libnetaid is available here.
Download the tarball from the git repository of devuan snetaid,
extract it with
tar xvf master.tar.gz and go into the extracted folder. There, run the
$ mkdir build $ cd build $ cmake .. $ make $ sudo make install
Note: By default, CMake does not provide the “make uninstall” target; so, in general, you cannot do this. However, snetaid adds an uninstall target to the CMAKE generated Makefile, in such a way that you can run:
$ sudo make uninstall
If the library in
/usr/local/lib is not found (this is the destination when building from source), what you need to do is to tell
the runtime loader to also look in this directory for libraries. There are two ways for that:
/etc/ld.so.conffile, by putting the line
/usr/local/libsomewhere in that file, or by creating a new *.conf file in the
/etc/ld.so.conf.d/directory that contains the new path. For example
/usr/local/libin it. This is the recommended way of doing this, as it allows you to keep your custom library paths separate from paths set by the system. The “99” prefix is there to make sure the file is loaded last compared to other files there, so that it won’t preempt system paths that could contain the same libraries (read here). After you modify/create the file in
/etc, you need to update the
$ sudo ldconfig
You can test snetaid running the binary from the command line:
But this way does not run the daemon. Let’s have a look at the command line parameters and arguments:
snetaid -- Simple Netaid Daemon Usage: snetaid [options] Options: -a --conf_file filename Read configuration from the file -l --log_file filename Write logs to the file -p --pid_file filename PID file used by daemonized app -b --background Run in the background -f --foreground Run in the foreground (Default) -s --stop Stop the service once the connection has been stablished -h --help Show this help -k --kill Kill a running daemon -c --check-running Check if a daemon is currently running
-b option is append, it will become real UNIX daemon. However, this
is not the way how UNIX daemons are started nowdays. Some init scripts
or service files must be used for this purpose.
For instance, if you are using sysvinit as init system, then you should be able to control the daemon via:
service snetaid start service snetaid status service snetaid reload service snetaid stop
The third command reloads the configuration file restarting the daemon afterwards.
snetaid detects whether the ethernet cable has been plugged in, in which case it will try to connect to the wired device in the first place. In order to carry out a wireless connection attempt you need to install some available active wifi in “/etc/network/wifi” by using the wpa_passphrase command as follows:
wpa_passphrase ESSID PASSWORD > /etc/network/wifi/<some_descriptive_name_for_the_wifi>
The daemon will do the rest.

Please make sure to update tests as appropriate.
