Hello,

just to verify, is port `2022` correct? Usually `CONFD_PROT` is used (value `4565`) unless overridden (see `/confdConfig/confdIpcAddress/port` and `28.6. ConfD IPC` in the ConfD User Guide). `2022` is usually assigned for `NETCONF` port (`/confdConfig/netconf/transport/ssh/port`).

Then you need to use:

```auto
new Socket("localhost", Conf.PORT)

```

Thanks, now I am able to make the connection but locally only  
  
127.0.0.1  
4565

But if i use some remote ip like  
  
10.204.42.57  
4565

where 10.204.42.57 is the ip of my windows machine from where I am making the socket connection…

confd --reload gives the error –  
Cannot bind to internal socket 10.204.42.57:3465 : can’t assign requested address
