Meshcentral: Need help server is now running on Port 1029

[haxmachine]

My meshcentral server has always been running on port 1027 and for some reason my server went down and now when i start it,
it runs on port 1029 and none of my clients report back now.
is there a way i can start the service on a specific port.

the command i use to start meshcentral is
nohup node ./node_modules/meshcentral &

any help would be appreciated thanks.

Hi. The quick answer is that your probably running MeshCentral twice or more. Do ps -aux | grep mesh and look to see if other processes are running.

The longer answer is that MeshCentral will try to use the ports that are specified in config.json, but if not available will use the next available port. So, if 1027 is busy and it's going to jump to the next available higher port. Your going to have to stop MeshCentral, stop the process that is using port 1027 and start MeshCentral again.

Try running MeshCentral without the & at the end and you will see what ports it's using and can hit ctrl-c to stop and start again. Should make it easy to see what is going on.

Hope that helps,
Ylian

So, screen shows MeshCentral running. Your going to have to diagnose this a bit more. Kill that version and try running it again.

i have stopped meshcentral and confirmed with my Host that port 1027 is free and available yet meshcentral wants to start on 1029.
is there a way i can set the port in the config.json to always use port 1027?

confirmed with my Host that port 1027 is free

Do you mean you have verified yourself that nothing else is running on that port? What does netstat -tulpn show ?

[Ylianst]

There is a sample config.json here and a more advanced sample here.

You can set the port like this:

{
  "settings": {
    "cert": "myserver.mydomain.com",
    "_WANonly": true,
    "_LANonly": true,
    "port": 443,
    "redirPort": 80
  },
  "domains": {
    "": {
      "_title": "MyServer",
      "_title2": "Servername",
      "_minify": true
    }
  }
}

Change port 80 and 443 to the ports you want.

I also would like to know what "netstat -tulpn" returns.

I wasnt able to run the command netstat -tulpn it returned the below message

[haxmachine]

also changed these to 1027 and some reason it still start on 1029

@haxmachine The Port and RedirPort values have to be different; they can't occupy the same port.

[Ylianst]

RedirPort is a HTTP port that typically redirects users to the HTTPS port, it's optional, if you don't want it, put 0 as the value.

Whats your OS ?

[haxmachine]

Its running on my web-host shared server which is a Linux distro not sure which one though.

[whalehub]

@haxmachine You can find out which distribution you're running by executing the following command(s):

cat /etc/issue
cat /etc/*-release
cat /proc/version

If netstat isn't installed on it by default, which seems to be the case here, you can get it by installing the package net-tools.

netstat is not included in redhat by default I believe, try:

[haxmachine]

since its on a shared webhost i will not be able to run that command, the helpdesk assure me that port 1027 is not being used by anything

[haxmachine]

any other ideas ive been trying my hardest to get it to run on port 1027 but it always goes to port 1029
