Failed to listen for TCP connection / Can't create socket

[betzburger]

Hello,

DtCyber runs very well on my Raspberry as well as on my Linux Mint system.
On macOS I am facing a strange problem. I am sure this is on my side, but I am stuck.
Any hint is welcome.

This is the output after I entered "sudo node start" in NOS 2.8.7:

Hi Peter, There are a couple of possibilities: 1. DtCyber ran previously and exited abnormally without being able to stop its "helper" processes properly. Enter the "ps ax" command and look for processes named "webterm-server", "STK4400", "rjews", and "console-server". Terminate these using "sudo kill <pid>", if any are running. If any of them are running, they might be holding ports 175 and 16612 open. 2. Some other process on your system is using port 175. To work around this, update your cyber.ovl file to choose a different port on which DtCyber should listen for NJE connections. Find this line in cyber.ovl: terminals=*175*,0x30,1,nje,98.0.36.170:175,NCCMAX,B8192 and change the first occurrence of 175 to another port number, for example, 1175, as in: terminals=*1175*,0x30,1,nje,98.0.36.170:175,NCCMAX,B8192 cheers, Kevin

(console) Failed to listen for TCP connections on port 16612 (NPU_net) Can't create socket for port 175 IIRC MacOS requires root permissions to bind to low ports (<1024) or to create a SOCK_RAW socket. Kevin, is that handled here? De

[kej715]

Peter indicated that he tried starting DtCyber using the command “sudo node start”, so it would have been started as root and binding to port 175 would be allowed, unless another process was already bound to that port.On Dec 25, 2023, at 4:38 PM, Dennis Boone ***@***.***> wrote: (console) Failed to listen for TCP connections on port 16612 (NPU_net) Can't create socket for port 175 IIRC MacOS requires root permissions to bind to low ports (<1024) or to create a SOCK_RAW socket.

Port was indeed blocked by another process. I "killed" it. Maybe it had to do with things that I had to install to get everything up and running (XQuartz, Homebrew, ..) But even after I did a restart, the port is not blocked anymore and DtCyber runs fine.
Well, seems okay. now. Thanks!
