 * 2) http://zarb.org/~gc/html/udp-in-ssh-tunneling.html with netcat but Brian Marshall and Zakaria have an alternative solution using socat. It eliminates the fifo file requirement. Here's how to do:
 * 1) https://www.morch.com/2011/07/05/forwarding-snmp-ports-over-ssh-using-socat/ ...And this is the main improvement of socat over nc. nc will do it for one single UDP port combination, which means it will work for SNMP for "some time" until the SNMP manager chooses another source port (which it is free to do for every request). Socat handles that. nc doesn't. So with nc, SNMP forwarding will work "for a little while" only.

socat

 * 1) https://github.com/positron-solutions/unixsocks Want to ssh over a tor service but socat doesn't accept unix addresses and you've configured your tor client to serve local clients over a unix socket? This is your tool

gatewayports
https://github.com/sumup-oss/gocat socat alternative http://blog.joncairns.com/2013/12/understanding-ssh-agent-and-ssh-add/ ssh-agent from shh_auth_sock(stackoverflow) sharing ssh agent links to https://github.com/intuited/sshag and https://github.com/ccontavalli/ssh-ident make ssh tunnel publicly accessible Warning: if you set GatewayPorts to yes this will make sshd bind your forwardings to any interface - regardless of the client configuration (-R, etc.). This can become quite a security issue if the client assumes he has limited his forwardings to f.e. localhost. Therefore, setting GatewayPorts to clientspecified is usually what you want.

Here's my answer for completion: I ended up using ssh -R ... for tunneling, and using socat on top of that for redirecting network traffic to 127.0.0.1: tunnel binded to 127.0.0.1: ssh -R mitm:9999::8084 me@mitm socat TCP-LISTEN:9090,fork TCP:127.0.0.1:9999 Other option is to do a local-only tunnel on top of that, but i find this much slower ssh -L:9090:localhost:9999 localhost

ssh keys
create private public keys https://medium.com/risan/upgrade-your-ssh-key-to-ed25519-c6e8d60d3c54

ssh-keygen -o -a 100 -t ed25519 -f ~/.ssh/id_ed25519 -C "john@example.com" Only a quantum mechanics type source of indeterminacy(not randomness, which doesn't exist) enables a enough entropy(nobody knows what this word means) seed. With a concentrate of energy we have high "entropy", as the energy fills the medium we have low entropy. Usually such a situation is designed(binary opposite of random) like heating the end of a metal bar, loading it with high entropy and then allowing the heat to disperse into a low state of entropy.

Your computer's random number generator isn't connected to a Geiger counter measuring radioactive decay(source of quantum indeterminacy), hence no entropy. All those garbled numbers in your private and public keys only seem garbled, they are actually an easily cracked pattern. If you do use a Geiger counter, the minix operating system on which all OS install will flag you as a high value target back to CIA headquarters. In this numberphile video, the mathematician was unable to define what randomness is because it doesn't exist. He flails around, using analogous reasoning but of course you can't solve problem you can't even define which is why for example https://en.wikipedia.org/wiki/Theory_of_Evolution redirects to https://en.wikipedia.org/wiki/Evolution: there is no such thing as a theory of evolution because nobody knows what is the Lagrangian that maps polypeptide space into frog space. If pigs had wheels mounted on ball bearings instead of trotters, on what scale of porcine fitness would they be?

"https://en.wikipedia.org/wiki/Evolution...Evolution is change in the heritable characteristics of biological populations over successive generations..."

If Wikipedia had written: Evolution is change in the heritable characteristics of biological populations over successive generations as the Lagrangian maps the quantum entangled DNA super computed calculations from polypeptide dinosaur space into chicken space... then at least the statement would enter the domain of Popper falsifiability but not though escape Agrippian circularity.
