yes. For this I use socks proxy over ssh (-D option), and proxychains for the client program.

Eg.
Create the tunnel

Code:

ssh -f -N -D localhost:5555 myserver.some.where

Configure proxychains

Code:

echo 'socks4 127.0.0.1 5555' >> /etc/proxychaings.conf

Use the tunnel with some program

Code:

proxychains someprogram

HTH,

Hi,

one more thing, you don't need root for this since proxychains will also look for a config file in ~/.proxychains.conf

copy paste with code flags what you did and what happened directly from the CLI.

i ran the following command to open the socks proxy on port 5555:

Code:

ssh -f -N -D localhost:5555 server.ip

i then saved the following in /etc/proxychains.conf (well i edited the old config to remove the default tor line etc):

Code:

socks4 127.0.0.1 5555

i then ran the following (just a test i know it can be done within chrome much better etc):

Code:

proxychains /usr/bin/google-chrome-stable

all i get is 'This web page is not available' via chrome (and likewise other apps also have no internet access)

this is the output via command line for the above command: http://pastie.org/pastes/8906135/tex...utkrtjfznfd2bw

Hi,

ok from the pastebin I can see that libproxychains.so.3 is not being found. Was ldconfig run by the postinstall script? If not please try running it now (as root). You may also need to log out and back in again (but I'm just guessing here).

If the above fails then _instead_ of running the proxychains script do:

Code:

export LD_PRELOAD=/usr/lib/libproxychains.so.3
someprogram

The only difference between this and using the proxychains script is that the full path is specified for LD_PRELOAD.

/usr/lib/libproxychains.so.3 isn't on my system? :/

evo2 · 03-10-2014, 11:50 PM

Hi,

what is the output of the following?

Code:

find /usr/lib -name libproxychains.so.3

Evo2.

steve51184 · 03-10-2014, 11:50 PM

/usr/lib/x86_64-linux-gnu/libproxychains.so.3

evo2 · 03-10-2014, 11:52 PM

Hi,

ok, so use that path.

Evo2.

steve51184 · 03-10-2014, 11:53 PM

sorry to sound dumb but what do i do with the following? :/

Code:

export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libproxychains.so.3
COMMAND

evo2 · 03-10-2014, 11:56 PM

Hi,

run it in a terminal replacing "COMMAND" with whatever command you want to run eg chrome-chrome-stable. Look at the contents of /usr/bin/sockproxy to understand why.

steve51184 · 03-10-2014, 11:59 PM

/usr/bin/sockproxy is empty :/

also same problem no internet access for the app although the libproxychains.so.3 error is gone:
