Auto starting an application during boot
Crosslink TG uses systemd as a service manager. Systemd provides an easy way of setting up
services on the device.
To create an application that will launch during the boot up, a .service file should be created.
A typical configuration file can look like this:
[Unit]
Description = Example that runs an application during boot
After = syslog.target
[Service]
ExecStart = /opt/bin/myApplication
[Install]
# multi-user.target corresponds to run level 3
WantedBy = multi-user.target
You must also create (as root user) a file named
myapplication.service
in folder
/etc/systemd/system
to complete the process.
5.
Security
The CrossLink TG is by default an open device and not suitable for connection to the Internet
directly. There are a few simple steps to take to improve security.
Change the user password from default. Both for root and debian users.
Verify that root login via SSH is disabled.
Activate the built in firewall (see below)
Use a SIM card with a customized APN / VPN solution to only allow access to a specific
server.
