Connect to my ssh server via lokal port

3 posts in this topic

#1 ·  Posted (edited)

Hi,

I created simple proxy to allow me to connect to my secure sh server.

But i cannot successfully connect.

Updated:

Finally i can reach my vps server, modified some code from another thread.

but there was another problem:

It said that the connection has been terminated due to a time-out or other failure. [Error WSAECONABORTED]

Here is my code:

#Region ;**** Directives created by AutoIt3Wrapper_GUI ****
#AutoIt3Wrapper_outfile=proxy.exe

Where are you trying to connect from? Is it in your local network? Or is it from outside your network?

There are a few things that you have to consider:

1. Are your firewall settings correct?

2. Have you properly forwarded your ports?

3. Is your AV possibly blocking traffic on that port?

Best advice, get it working locally first, then work on setting firewall rules and forwarding your ports.

Yea i first listen to local port and then connect to my vps through that port.

I just updated the first post.

Any help appreciated
