Hi guys,

I am novice in linux.

I'm trying to access a linux machine.

But it returns the error message. ERR_CONNECTION_REFUSED

I used the a command to iptables -F and iptables -X. Even so, when I try to access it still gives the same error = ERR_CONNECTION_REFUSED

What can I do?

There may be various reasons for connection refused... possible reasons are...

  • The IP address does not exist
  • There is no route to that IP address (mis-configuration)
  • There is a firewall which is blocking access
  • There is no service listening on the port. For "https", the default port is 443.

  • Unfortunately, the error message does not provide enough information to tell you what the issue is. The error message simply states that it doesn't have access.

    Wow, something I actually know something about.

    My head ain't right at the moment but that error means 1 of 2 things:

    1)  You can't access that IP address
    2)  You're hitting a port where nobody is listening.

    How to fix:

    1.  Ping the IP.  If you can reach it goto step 2.  Otherwise figure out why you can't ping it.
    2.  On the remote system (note:  remote could be the same box if your IP is, commonly known as localhost.  Hint:  this is a great way to debug your stuff) ensure your server is running.
        a)  It's not.  Start it.
        b)  It is.  Debug it  That is, debug the server, not the client.
        c)  You don't own the IP address.  This is a whole 'nuther issue I won't touch here.  But, um, cough, nmap -sP IP/8 could be a start.
