OpenSSL: socket: Connection refused connect:errno=111

I am trying to connect to one Linux server from a client,

openssl s_client -connect <IP of Server>:443

I am getting the following error:

socket: Connection refused
connect:errno=111

Solution

  • Check the ports of the server by any tool. For Example,

     nmap <IP>

Starting Nmap 5.21 ( http://nmap.org ) at 2015-05-05 09:33 IST
Nmap scan report for <IP>
Host is up (0.00036s latency).
Not shown: 996 closed ports
PORT    STATE SERVICE
22/tcp  open  ssh
111/tcp open  *****
139/tcp open  *****
443/tcp open  openssl
MAC Address: 18:03:73:DF:DC:62 (Unknown)

    Check the port number is in openstate.
