tsocks and OpenSSH

Question

I try to use tsocks as a socks-wrapper for an OpenSSH socks5 tunnel:

Here's my tsocks.conf:

wishi@kage ~ % cat /etc/tsocks.conf
# This is the configuration for libtsocks (transparent socks)
# Lines beginning with # and blank lines are ignored
#
# This sample configuration shows the simplest (and most common) use of
# tsocks. This is a basic LAN, this machine can access anything on the 
# local ethernet (192.168.0.*) but anything else has to use the SOCKS version
# 4 server on the firewall. Further details can be found in the man pages,
# tsocks(8) and tsocks.conf(5) and a more complex example is presented in 
# tsocks.conf.complex.example

# We can access 192.168.0.* directly
local = 192.168.0.0/255.255.255.0

# Otherwise we use the server

server = 192.168.0.1
# Server type defaults to 4 so we need to specify it as 5 for this one
server_type = 5
# The port defaults to 1080 but I've stated it here for clarity 
server_port = 5000 

So:

ssh -D 5000 me@server

And on another terminal:

tsocks transgui

No networking for the transgui application. I wonder what the issue is.

Answer 1

By default, ssh only listens for tunnel connections on the loopback interface – try changing your server to 127.0.0.1 or ::1.

If you need to connect from outside, use either ssh -g -D 5000 or ssh -D "*:5000".

Answer 2

Use ssh -L instead of -D

it uses local ports instead of dynamic if i remeber correctly, gives you less headache.

ssh -L LOCAL_PORT:SERVER:SERVER_SOCKS_PORT SERVER

this way you can also access a proxy server behind a ssh proxy
