ssh -D 8080 user@host

or

ssh -gCNf -D 8080 user@host

or

wathever with -D #

I need a kind of proxy that i can use with http_proxy variable, in an embedded device that doesn't support SOCKS.

What should i do?

Shouldn't it be ssh -D user@host:8080 ? –  ngen May 6 '11 at 14:51
    
i've done it with ssh a while back.. vnc through ssh. but you could I suppose use squid(an http proxy) through ssh. can't recall how i did it though at the moment. it's not -D 'cos (as you know -and better than me) -D is SOCKS if I recall. –  barlop May 6 '11 at 15:03
    
@ngen: No. -D specifies a port to open the tunnel on, not the port to connect to. (Even the connection port is specified as -p port, not :port, for compatibility reasons.) –  grawity May 6 '11 at 15:05

  • Establish the tunnel normally, then start a HTTP proxy that supports using a SOCKS upstream, such as Polipo or Privoxy. Point your program to that proxy on localhost.

    Example Polipo configuration:

    proxyAddress = "::1"
    proxyPort = 8118
    socksParentProxy = "localhost:8080"
    socksProxyType = socks5
    
  • Run your program inside the tsocks wrapper, which proxies all connections transparently.

  • As others suggested, set up a HTTP proxy on your server, then access it over SSH using ssh -L.

Thanks, I'll try all of them. –  behrooz May 6 '11 at 15:32

ssh -L 8080:localhost:12345 user@host

This will open port 8080 on the local machine, and forward all data to port 12345 on localhost, as seen from the remote machine.

Every -D results into a SOCKS server. If your client can not handle SOCKS forget -D.

You must run a HTTP-Proxy on the remote host and forward with -L:

ssh -f -N -n -L8080:127.0.0.1:8080 host

Run Privoxy at the remote host, then connect via SSH to Privoxy using the -L option:

-L [bind_address:]port:host:hostport
         Specifies that the given port on the local (client) host is to be
         forwarded to the given host and port on the remote side.  This
         works by allocating a socket to listen to port on the local side,
         optionally bound to the specified bind_address.  Whenever a con-
         nection is made to this port, the connection is forwarded over
         the secure channel, and a connection is made to host port
         hostport from the remote machine.
