I am trying to debug a remote application. I have initiated a SOCKS proxy on server: ssh -D 9999 hostname
I then try to connect to it from my eclipse debug setting where hostname is the same and port=9999.
However I get error:
channel 3: open failed: connect failed: Connection refused
I have also update eclipse network connections to allow SOCKS proxy. The configuration works on a different host name in the same network.
I am not able to interpret this error message. Can someone please assist where I am going wrong? I looked at this: SSH -L connection successful, but localhost port forwarding not working "channel 3: open failed: connect failed: Connection refused" but did find it useful in my case.
I have initiated my process on remote server in debug mode listening a specific port 4111
I confirmed that debug port is open by netstat -a command
Thank-you

Your local computer doesn't have an SSH client installed To establish an SSH connection, your computer must have a program called SSH client. It allows you to communicate with a remote server and execute SSH commands. If the program is missing, you will see the SSH “Connection refused” error.
To terminate the ssh tunnel, run ps aux | grep ssh , search for the correct tunnel and PID, and then run kill 12345 replacing 12345 with the PID on your machine.
SSH tunneling, or SSH port forwarding, is a method of transporting arbitrary data over an encrypted SSH connection. SSH tunnels allow connections made to a local port (that is, to a port on your own desktop) to be forwarded to a remote machine via a secure channel.
AllowTcpForwarding Specifies whether TCP forwarding is permitted. The default is ''yes''. Note that disabling TCP forwarding does not improve security unless users are also denied shell access, as they can always install their own forwarders.
Rather than relying on SOCKS proxying, use
ssh -L4111:localhost:4111 server
To establish a direct connection across the ssh tunnel.
