When starting the driver on the following "Specific device" or "Network device",
the device connection may fail.
[Cause]
Access to the local host is blocked by the firewall settings in the customer environment.
[background]
Epsonscan2 Linux internally starts a process for command communication
and exchanges data by interprocess communication.
Interprocess communication is realized by network communication by TCP / IP and is affected by Firewall.
[Checkpoint]
Check the Firewall settings,
and if packets are blocked to the local host, please release it.
If you are using "iptables" which is a standard Linux firewall,
you can check the settings with the following command.
# sudo /sbin/iptables -nL
Check the above command, and if access to the local host is blocked,
please review the firewall settings by yourself.
* There is a possibility that the customer is using a firewall other than iptables.
In that case, please read the settings of the firewall software you are using and check.
