Rxtx no permission to create lock file

The text was updated successfully, but these errors were encountered:. Sorry, something went wrong. That is linked to the rxtx lib. In later projects I use a serial port lib from google that works better. But as said this project is 8 Years old and not of priority for me.

Just add yourself to the lock group or run elevated,. Skip to content. Star New issue. SerialPorts and gnu.

If either of these is set, then no scanning will be carried out and only the specified ports will be available. You can use this to make one platform look like another, to restrict Java access to ports, or possibly for other reasons. For example. A note on Linux port enumeration. We have set most ports aside. Once the number of possible devices started getting into the thousands, checking them all made little sense.

Just copy the few you need. The RXTXcomm. In this code, you will find. Make sure the new compiled file goes into the right place. One way is to extract all files from RXTXcomm. Create a new RXTXcomm. Replace this new updated jar file with the old one. RXTX uses lock files by default. Lock files are used to prevent more than one program accessing a port at a time. Lock files may require a bit of sysadmin to work properly.

If you do not want to use lockfiles in RXTX, run 'configure' with option '--disable-lockfiles'. It is however strongly recommended that you do use lock files to prevent RXTX from stomping on other programs that might use the serial ports concurrently. RXTX has support for lock files on Linux only. It may work on other platforms but read the source before blindly trying it. In this case 'jarvi' is the login name for the user that needs to use lock files.

Do not change the number Whatever is in your group file is correct. On Red Hat, do this also for group 'lock'. Why: from Red Hat 7. On the other hand, the serial device files are owned by group 'uucp' and are not world-writeable by default.

Thus any user which may or may not actually be using uucp See also I cannot open the port. You may need to create the lock directory with group 'uucp' ownership. There is a script in 'contrib' called 'fixperm. As another option it is possible to use a Lock File Server. In this case, a server runs in group 'uucp' or 'lock' and rxtx then connects to localhost to lock and unlock the port.

It fails with the given message above. Maybe restarting the device could help? Fun fact: adding the controller always works. Kai any builds available in between M1 and M2 to bisect the issue? M1 was done on Aug 15 and M2 on Aug 28, so you might want to check the snapshots between those dates - I am just not sure, if those are still anywhere available.

Here you can see the changes between the two milestones. As this happens with Z-Wave dongles, maybe chris has any input on the issue? It is mine Setup, Configuration and Use Installation. Any ideas? Regards, Bastiaan. If you shutdown OH, delete the files, and restart OH, do you still get the error? To me it looks like a threading issue.

It is mine testRead Lock file failed. M1 works 2. M2 controller added successfully, discovery fails 2. M3 controller added successfully, discovery fails 2.
