ser2netweb shares local serial ports over the network (raw TCP, telnet, RFC 2217, UDP), is a Modbus RTU/TCP gateway and publishes to MQTT and Sparkplug B, all set up in a web UI. It is an independent project (named ser2net up to 2.9.x), not related to the classic ser2net daemon, whose configuration files it can import.
USB serial adapters (/dev/ttyUSB*, /dev/ttyACM*, also by /dev/serial/by-id) need the raw-usb interface: sudo snap connect ser2netweb:raw-usb The service is off after installing: sudo snap start --enable ser2netweb.daemon Its web UI then listens on 127.0.0.1:8080; for the network: sudo snap set ser2netweb bind-ip=0.0.0.0 port=8080 Its data is in /var/snap/ser2netweb/common/data. The first admin password: sudo ser2netweb --data-dir /var/snap/ser2netweb/common/data --set-password admin

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
Snap is available for CentOS 7.6+, and Red Hat Enterprise Linux 7.6+, from the Extra Packages for Enterprise Linux (EPEL) repository. The EPEL repository can be added to your system with the following command:
sudo yum install epel-release
Snap can now be installed as follows:
sudo yum install snapd
Once installed, the systemd unit that manages the main snap communication socket needs to be enabled:
sudo systemctl enable --now snapd.socket
To enable classic snap support, enter the following to create a symbolic link between /var/lib/snapd/snap and /snap:
sudo ln -s /var/lib/snapd/snap /snap
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
To install ser2netweb, simply use the following command:
sudo snap install ser2netweb
Browse and find snaps from the convenience of your desktop using the snap store snap.
