The guide is essentially a compilation of various posts and your own research.
Linux socat tutorial serial#
Ser2net is installed on the server and shares the serial port on the network and socat is installed on the client and provides the interface there.
Linux socat tutorial Bluetooth#
the Bluetooth adapter from BlueGiga or a Z-Wave adapter like the one from Aeotech, the solution can be the combination of ser2net and socat. If you now have a USB adapter that looks like a serial interface, e.g.
Solution 2: ser2net and socat for serial USB ports sudo modprobe vhci-hcdįor the removal of the connection refer to the above mentioned blog article “ Linux, RPi and USB over IP updated”
Attention: On a Raspberry I did not succeed in integrating the adapter. The Bluetooth adapter is now shared on the network and can be integrated with the following commands. : Wireless / Radio Frequency / Bluetooth (e0/01/01) Exportable USB devicesġ-1.3: Cambridge Silicon Radio, Ltd : Bluetooth Dongle (HCI mode) (0a12:0001) The result of the list command should be something like this. IP address should be replaced with the IP address of your server. After that we can check if our enabled adapter is visible. sudo usbip -debug bind -b 1-1.3Īnd now we come to the client side, the openhab server. With a bind it is bound and shared on the network. The one we are looking for has the bus id 1-1.-3 and is a bluetooth adapter. : SMSC9512/9514 Fast Ethernet Adapter (0424:ec00)Ĭambridge Silicon Radio, Ltd : Bluetooth Dongle (HCI mode) (0a12:0001) Then the usbip daemon is started and the matching USB adapter is identified and shared.
Linux socat tutorial install#
We omit the check whether the kernel is prepared for it, since this is usually the case in current kernels sudo apt install usbip Hierzu muss zunächst usbip installiert werden. The guide is based on the blog entry “ Linux, RPi and USB over IP” by Piotr Król and is a little shortened here.Įrste Schritt ist das Aufsetzen des Servers, an dem der USB Adapter angeschlossen ist. Disadvantage: I got it to run on the server (the one with the adapter), but not on the openHAB site (the client) yet. In contrast to the ser2net / socat combination, this solution can be used for any USB port. And openhab runs on a Raspberry Pi 3 with SSD and a manually installed openHabian and Raspbian Stretch (Kudos to 1: USBIP for non-serial USB ports I use a first generation Raspberry Pi with DietPi as OS for the server (which comes with the adapter). The server on which openHAB runs is always referred to as the client and the server to which the respective adapter is connected is referred to as the server. For serial ports the combination of ser2net and socat and for USB ports usbip is a possible solution.īefore we start, here are some definitions. In order to solve this problem, there are two solutions, depending on the task, which are briefly presented below. However, if the cable length is limited or the installation of cables is not possible, this does not lead to the desired success. To improve the range, the corresponding adapters can be connected with extension cables. Services such as Zwave or Bluetooth are limited in their transmission range for technical reasons. This tutorial is the result of my efforts to use Vlad Kolotov’s Bluetooth binding (kudos to ) for my MiFlora plant sensors. If you want to learn more, check out the socat man page, section “ADDRESS TYPES” or the online documentation.As promised, here comes the tutorial on forwarding serial or USB ports to openHAB. I hope you enjoyed this quick socat tutorial.
socat TCP4-LISTEN:5000,fork OPENSSL:localhost:443įinally if you are tunneling a connection between servers using socat you can use the -v option to print all the traffic to stdout. You should also check out the options that you can apply, for example you can use fork to tell socat to listen and handle multiple clients. SSL server socat OPENSSL-LISTEN:443,cert=/cert.pem - SSL client socat - OPENSSL:localhost:443īoth addresses don’t have to use the same protocol, so you can do “ssl server -> non-ssl server”. Openssl req -new -x509 -days 365 -nodes -out cert.pem -keyout cert.key Now we can go beyond netcat with some ssl examples, but first we need to generate a ssl cert for the server. Socat TCP4-LISTEN:700 STDOUT nc -lp localhost 700 -e /bin/bash Socat - TCP4:localhost:80 OR socat STDIN TCP4:localhost:80 nc -lp localhost 700 First I want to show you how you can get the same functionality as with netcat. You have to provide both addresses in order for it to work, now these addresses look like this: protocol:ip:port The first thing you will notice with this tool is that it has a different syntax on what you are used to with netcat or other standard unix tools.
Linux socat tutorial windows#
Socat supports ipv6 and ssl and is available for both windows and linux. Socat is a network utility similar to netcat.
