Description for DNS2SOCKS
|
||||
-------------------------
|
||||
|
||||
DNS2SOCKS is a command line utility running to forward DNS requests to a
|
||||
DNS server via a SOCKS or HTTP tunnel.
|
||||
|
||||
I know that this is no new idea, but let me explain why I've coded this:
|
||||
Windows supports using a SOCKS server for Internet connections, but it
|
||||
only uses the SOCKS server for the content and not the DNS requests. I
|
||||
found several articles in the Internet referring this issue. There seem
|
||||
to be tools that do exactly the same thing as DNS2SOCKS, but they either
|
||||
need a scripting interpreter or are not available for downloading anymore.
|
||||
|
||||
So I've coded an own tool. It's very(!) simple and doesn't use any
|
||||
sophisticated technology.
|
||||
|
||||
To use it, just configure your OS to use the DNS server on the local
|
||||
IP address 127.0.0.1 (IPv4) and/or ::1 (IPv6). On Windows: open the
|
||||
properties of your network adapter. For IPv4 open the properties of
|
||||
"Internet Protocol Version 4 (TCP/IPv4)", select "Use the following DNS
|
||||
server addresses" and enter "127.0.0.1" for the "Preferred DNS server".
|
||||
For IPv6 open the properties of "Internet Protocol Version 6
|
||||
(TCP/IPv6)", select "Use the following DNS server addresses" and enter
|
||||
"::1" for the "Preferred DNS server".
|
||||
|
||||
After that run your SOCKS server (must support SOCKS protocol version 5,
|
||||
for example Tor) or HTTP proxy and start DNS2SOCKS using the correct
|
||||
command line switches (see below). Now all DNS requests of your OS
|
||||
(triggered by any application) run through DNS2SOCKS and your SOCKS
|
||||
server or HTTP proxy.
|
||||
|
||||
You can additionally configure Windows to use your SOCKS server for
|
||||
Internet connections (for the content, not DNS). To do this open the
|
||||
"Internet Options" of the control panel, select the tab "Connections" and
|
||||
click on "LAN settings". Check "Use a proxy server for your LAN..." and
|
||||
click on "Advanced". Enter your SOCKS server address and port in the field
|
||||
"Socks". Now Internet Explorer and other tools using these settings get
|
||||
web pages via your SOCKS server. This works with most browsers. However,
|
||||
you should rely on IPv4 for Tor here as (most?) Tor exit servers currently
|
||||
don't support IPv6 (see below).
|
||||
The settings are similar for using a HTTP proxy.
|
||||
|
||||
The command line call for DNS2SOCKS has the following format:
|
||||
|
||||
DNS2SOCKS [/?] [/t] [/d] [/q] [l[a]:FilePath] [/u:User /p:Password]
|
||||
[/e[f]:IP/Bits]
|
||||
[Socks5ServIP[:Port]] [DNSServIPorName[:Port]] [ListenIP[:Port]]
|
||||
|
||||
/? or any invalid parameter outputs the usage text
|
||||
/t to use a HTTP proxy instead of a SOCKS server
|
||||
(here: Socks5ServIP = HttpProxyIP, no support for /u and /p)
|
||||
/d disables the cache
|
||||
/q disables the text output to the console
|
||||
/l:FilePath creates a new log file "FilePath"
|
||||
/la:FilePath creates a new log file "FilePath" or appends to the file if
|
||||
it already exists
|
||||
/u:User user name if your SOCKS server uses user/password
|
||||
authentication
|
||||
/p:Password password if your SOCKS server uses user/password
|
||||
authentication
|
||||
/e:IP/Bits to enable and specify EDNS client subnet in DNS queries
|
||||
/ef:IP/Bits same as above but also replaces EDNS client subnet if it
|
||||
exists
|
||||
|
||||
The default values for the addresses and ports are (in case you don't
|
||||
specify the command line arguments):
|
||||
Default Socks5ServerIP:Port = 127.0.0.1:9050
|
||||
Default DNSServerIPorName:Port = 46.182.19.48
|
||||
Default ListenIP:Port = 127.0.0.1:53
|
||||
|
||||
So the SOCKS server runs locally on the TCP port 9050 (Tor's default port;
|
||||
attention: for Tor Browser Bundle you must change it to 9150). The used
|
||||
DNS server is 46.182.19.48 (Digitalcourage e.V.). The DNS server must
|
||||
support TCP on port 53 as Tor doesn't support UDP via SOCKS. DNS2SOCKS
|
||||
listens on the UDP port 53 of 127.0.0.1 (only locally) - change this to
|
||||
0.0.0.0 for listening on all available local IPv4 addresses.
|
||||
|
||||
You can launch DNS2SOCKS several times with different settings, for
|
||||
example to listen on IPv6 addresses additionally. To specify an IPv6
|
||||
address, use the typical format like 1234:5678::1234. To add the port
|
||||
number please embed the IP address in square brackets and add the port
|
||||
number separated by the colon, e.g. [::1]:1024
|
||||
|
||||
Hint: In the default configuration Tor only listens on 127.0.0.1 for
|
||||
incoming requests. You can change this in Tor's configuration file using
|
||||
the following line
|
||||
SocksListenAddress 192.168.1.1
|
||||
In this example it listens on 192.168.1.1
|
||||
Currently Tor doesn't support IPv6 addresses for listening.
|
||||
|
||||
Please note that Tor/Vidalia will output warnings that your application
|
||||
doesn't resolve host names via Tor. This is not true, but Tor can't know
|
||||
this as Tor doesn't recognize the tunneled DNS requests. DNS2SOCKS
|
||||
directly uses the IP address of the DNS server while using SOCKS and also
|
||||
your application will do this as it gets the IP address from DNS2SOCKS.
|
||||
Tor expects getting the host names instead of IP addresses and thus
|
||||
outputs these warnings.
|
||||
|
||||
However, instead of an IP address you can also specify the DNS server's
|
||||
name instead of its IP address, e.g.
|
||||
DNS2SOCKS 127.0.0.1 dns2.digitalcourage.de ::1
|
||||
Specifying an IPv6 address for the DNS server is also supported by
|
||||
DNS2SOCKS, but it's not recommended to do this as your current Tor exit
|
||||
server would need to support IPv6, which it typically doesn't. So it's
|
||||
better to specify the DNS server name as the exit server can choose IPv4
|
||||
or IPv6 automatically this way. Directly specifying an IPv4 address might
|
||||
be a bit faster; currently all Tor exit servers should support this.
|
||||
|
||||
Use the /e parameter to specify/overwrite the EDNS client subnet in your
|
||||
DNS queries. This is a hint for the DNS server to reply with IP addresses
|
||||
close to the specified subnet. It can speed things up. However, please
|
||||
be aware of the privacy risk. There are three possible variants DNS2SOCKS
|
||||
handles concerning the DNS requests if /e... is enabled:
|
||||
1. There is no OPT pseudo-RR -> DNS2SOCKS adds one with the EDNS client
|
||||
subnet option. It sets the DNSSEC flag to 0 as the original request
|
||||
didn't have it.
|
||||
2. There is an OPT pseudo-RR but no EDNS client subnet in it -> DNS2SOCKS
|
||||
only adds the EDNS client subnet option but doesn't change the rest.
|
||||
3. There is an OPT pseudo-RR including the EDNS client subnet. Now it
|
||||
depends what you specify:
|
||||
/e:... leaves it untouched.
|
||||
/ef:... overwrites the original EDNS client subnet (f=force).
|
||||
|
||||
As DNS requests running through the SOCKS/HTTP tunnel are very slow, the
|
||||
calling application might time out before it gets the answer - in this
|
||||
case just try it again (press "reload" in the browser).
|
||||
|
||||
The output of DNS2SOCKS is very simple. On each new request it outputs
|
||||
the requested name prefixed by the current number of entries in the
|
||||
cache (just an increasing number in case the cache is disabled) and a time
|
||||
stamp. DNS2SOCKS caches DNS requests, so the next time it can serve the
|
||||
answer faster. The cache is a very simple list. There is no sophisticated
|
||||
hash algorithm or something like that for the cache and DNS2SOCKS doesn't
|
||||
really interpret the DNS requests and answers - it just forwards them.
|
||||
|
||||
DNS2SOCKS runs as long as you don't manually stop it.
|
||||
You can also run several instances of DNS2SOCKS at the same time when
|
||||
using different local ports or IPv4 and IPv6 at the same time, e.g. use a
|
||||
batch file and Window's Start command to do this.
|
||||
|
||||
If you think that DNS2SOCKS is not the right tool for you, but you want
|
||||
to route all network traffic of a specific Windows application through a
|
||||
SOCKS tunnel, you might want to try my tool InjectSOCKS.
|
||||
|
||||
|
||||
|
||||
Now about some technical details:
|
||||
DNS2SOCKS listens on the local UDP and TCP port you specify. In case it
|
||||
gets a request it first searches the cache for an identical request.
|
||||
In case of a cache miss or expiration of the entry, the tool creates a new
|
||||
thread for resolving the request. The new thread opens a TCP connection to
|
||||
the SOCKS server and forwards the DNS request. This time the DNS request
|
||||
always runs on TCP as Tor currently doesn't support UDP via SOCKS. So the
|
||||
DNS server must support TCP. When the thread finally gets the answer, it
|
||||
forwards it via UDP or TCP to the requesting client and stores it in the
|
||||
cache. DNS2SOCKS supports user/password authentication (method 0x02) for
|
||||
SOCKS.
|
||||
|
||||
I've tried to comment the source code as good as possible and you can
|
||||
compile it using Visual C++ 2015 Express Edition (or any other edition).
|
||||
I've also tested it on Knoppix and Damn Small Linux and compiled it via
|
||||
gcc -pthread -Wall -O2 -o DNS2SOCKS DNS2SOCKS.c
|
||||
It should also run on other *nix variants; maybe with tiny modifications.
|
||||
|
||||
Have fun using this software!

|
||||
|
||||
|
||||
Changes of version 1.3 (released on 2012-11-03)
|
||||
-----------------------------------------------
|
||||
|
||||
- DNS requests/responses via TCP additionally to UDP (still always via
|
||||
TCP for transportation via SOCKS)
|
||||
- UDP requests/responses can now have the maximum possible size for UDP
|
||||
- You can specify the local port number to use for UDP and TCP
|
||||
- You can specify the remote port number to use for contacting the DNS
|
||||
server
|
||||
- You can compile the sources on Unix/Linux now and use it like on
|
||||
Windows. You only need DNS2SOCKS.c and stdafx.h for that and compile
|
||||
it with a command like
|
||||
gcc -pthread -Wall -O2 -o DNS2SOCKS DNS2SOCKS.c
|
||||
(tested on Damn Small Linux; use sudo to run it as otherwise it's
|
||||
impossible to bind port 53; please be aware that the connect time-
|
||||
out on Linux is typically several minutes while it is just some
|
||||
seconds on Windows, so in case connecting to the SOCKS server doesn't
|
||||
work, it takes very long until you see an error message)
|
||||
- On Windows DNS2SOCKS is no console application anymore, but it creates
|
||||
its own new console window at start-up; this way you can start it with
|
||||
the new /q option to suppress any output and it has no window in this
|
||||
case - use the Task Manager to terminate it
|
||||
- SHA1 for DNS2SOCKS.exe: 596015cba187a9184c5b480b8666c0d4b37d9552
|
||||
|
||||
|
||||
Changes of version 1.2 (released on 2012-01-13)
|
||||
-----------------------------------------------
|
||||
|
||||
You can configure the listen address via the command line now. The default
|
||||
is 127.0.0.1 instead of 0.0.0.0 of version 1.1. This way the Windows
|
||||
firewall doesn't show up.
