I want to setup a simple ssh tunnel from a local machine to a machine on the internet. I'm using
ssh -D 8080 -f -C -q -N -p 12122 <username>@<hostname>
Setup works fine (I think) cause ssh returs asking for the credentials, which I provide.
Then i do
export http_proxy=http://localhost:8080
and
wget http://www.google.com
Wget returns that the request has been sent to the proxy, but no data is received back. What i need is a way to look at how ssh is processing the request....

To enable SSH debug, run the SSH command with the -v, -vv, or -vvv option: In this example, you can see what a successful SSH connection would look like with the complete back and forth communication between the hosts. debug1: Connecting to 9.55. 216.115 [9.55.
The simplest way to test a ssh tunnel is with the telnet command and with a python http server. For reverse connection, this would be the following. On the local, install python3 and ssh, then. >telnet localhost 8080 Trying 127.0.
Troubleshooting steps:Verify that the host IP address is correct. Verify the firewall rules, check the inbound rules allowed by the security group. Verify the port number allowed for ssh. Verify that the service is running properly.
To get more information out of your SSH connection for debugging, leave out the -q and -f options, and include -vvv:
ssh -D 8080 -vvv -N -p 12122 <username>@<hostname>
To address your actual problem, by using ssh -D you're essentially setting up a SOCKS proxy which I believe is not supported by default in wget.
You might have better luck with curl which provides SOCKS suport via the --socks option.
If you really really need to use wget, you'll have to recompile your own version to include socks support. There should be an option for ./configure somewhere along the lines of --with-socks.
Alternatively, look into tsock which can intercept outgoing network connections and redirecting them through a SOCKS server.
