I have several generations of NAS from QNAP. QNAP removed sleep function on new NAS products Maybe the apache2 is preinstalled for a very long time but never initiated but the libapache2-mod-php8.1 upgrading process triggered it on.Īfter I purge apache2* and libapache2-mod-php8.1, the nginx can be restarted without any problem. I don’t find any log related to apache installation. Who wanna run apache aside nginx in a production environment, uhh?īy checking the log of apt, I found that php8.1 is upgraded with a library named libapache2-mod-php8.1 installed automatically. This server never has apache configured or started. When checking the status of nginx, it reports that port 80 is taken: nginx: bind() to 0.0.0.0:80 failed (98: Unknown error)Īnd the lsof command lsof -i -P -n | grep LISTEN

Today, after I fire a regular update by using apt update, apt upgrade and a reboot, my web server is down. I have a server using Ubuntu Server 22.04 LTS with nginx and php supported for a long time. Is there any approach to cancel the running Read method of FileStream without exiting application? And finally, the Thread.Abort is obsoleted and no use any more. Setting read timeout is not supported in FileStream. Cancel the CancellationToken cannot break the ReadAsync either. I also tried to use BinaryReader - “Stream was not readable” reported. And there is no way to break the waiting. If there is no data available currently but not reaching the end of file, it will block and wait. The Read method is designed to read at least one byte. The sad thing is, there is no way to stop the FileStream.Read method except quit the app.

For make it easy, I post the code in GitHub.

Using the method Read() form the instance of FileStream, all key events can be processed one by one. To read from the device in Linux, FileStream need to be created on the device file. Reading the event from keyboard device file /dev/input/eventX is a good choice. All devices are presented as files in Linux. Because the program is running background, hosted in systemd, there is no way to get the entered text from console. Switching to the second network card may help resolve this.Recently, I need to read the data from a code scanner, which is recognized as a keyboard, in the dotnet program development of Linux. A computer may have multiple Network Identification Cards (NICs).These settings might be absent at all or might look different depending on router model. Some of routers have features that allow to map multicast to unicast or simply block multicast packets. Direct multicast is disabled in router settingsĬheck your router settings.Make sure that your firewall is not blocking UDP packets coming to port 3838. It might be especially the case if peers are on different subnets, VPN. Multicast packets are not allowed in the network.If peers are in the same network and you are trying to connect devices over your LAN, these may be causing the problem: Troubleshooting will be the same as above, with proxy server involved. For that connection to relay server shall be possible for all peers. If direct connection is not possible, Sync will try to establish indirect relayed connection. Recheck traffic routing rules especially if multiple NIC are involved. Open Sync's listening port in your router and all possible firewalls in the way. Make sure that tunnel is actually possible in your network. Once Sync knows addresses of other peers, it tries to connect to them directly and establish UDP or TCP tunnel on given IP:port IP:port. Listening port of Sync may also be blocked.If for a reason it's not possible, use option 'Predefines hosts' and put there the address of a remote peer. Check that connection to tracker is allowed and that 'Use tracker' option is enabled in Sync settings. Once Sync learns addresses of tracker, it tries to connect to it to learn addresses of other peers. Check the file's availability with wget and try downloading it using a browser. Sync learns addresses of tracker and relay server from this nf file. If peers in a different network (not in your LAN) try to connect, but do not show up on Peer List window, there may be a few things happening that are preventing the peers from connecting.
