Tool for port forward & intranet proxy, just like lcx
/ ew
, but better
Why write?
lcx
and ew
are awesome, but can be improved.
when I first used them, I can't remember these complicated parameters for a long time, such as tran, slave, rcsocks, sssocks...
. The work mode is clear, why do they design parameters like this(especially ew
's -l -d -e -f -g -h
)
Besides, I think the net programming logic could be optimized.
For example, while running lcx -listen 8888 9999
command, client must connect to :8888
first, then :9999
, in iox
, there's no limit to the order in two ports. And while running lcx -slave 1.1.1.1 8888 1.1.1.1 9999
command, lcx
will connect two hosts serially, but it's more efficient to connect in concurrently, as iox
does.
And what's more, iox
provides traffic encryption feature. Actually, you can use iox
as a simple ShadowSocks.
Of course, because iox
is written in Go, the static-link-program is a little big, raw program is 2.2MB (800KB for UPX compression)
Feature
- traffic encryption (optional)
- humanized CLI option
- logic optimization
- UDP traffic forward (TODO)
Usage
You can see, all params are uniform. -l/--local
means listen on a local port; -r/--remote
means connect to remote host
Two mode
fwd:
Listen on 0.0.0.0:8888
and 0.0.0.0:9999
, forward traffic between 2 connections
./iox fwd -l 8888 -l 9999 for lcx: ./lcx -listen 8888 9999
Listen on 0.0.0.0:8888
, forward traffic to 1.1.1.1:9999
./iox fwd -l 8888 -r 1.1.1.1:9999 for lcx: ./lcx -tran 8888 1.1.1.1 9999
Connect 1.1.1.1:8888
and 1.1.1.1:9999
, forward between 2 connection
./iox fwd -r 1.1.1.1:8888 -r 1.1.1.1:9999 for lcx: ./lcx -slave 1.1.1.1 8888 1.1.1.1 9999
proxy
Start Socks5 server on 0.0.0.0:1080
./iox proxy -l 1080 for ew: ./ew -s ssocksd -l 1080
Start Socks5 server on be-controlled host, then forward to internet VPS
VPS forward 0.0.0.0:9999 to 0.0.0.0:1080
You must use in pair, because it contains a simple protocol to control connecting back
./iox proxy -r 1.1.1.1:9999 ./iox proxy -l 9999 -l 1080 // notice, the two port are in order for ew: ./ew -s rcsocks -l 1080 -e 9999 ./ew -s rssocks -d 1.1.1.1 -e 9999
Then connect intranet host
# proxychains.conf # socks5://1.1.1.1:1080 $ proxychains rdesktop 192.168.0.100:3389
enable encryption
For example, we forward 3389 port in intranet to our VPS
// be-controller host ./iox fwd -r 192.168.0.100:3389 -r *1.1.1.1:8888 -k 656565 // our VPS ./iox fwd -l *8888 -l 33890 -k 656565
It's easy to understand: traffic between be-controlled host and our VPS:8888 will be encrypted, the pre-shared secret key is 'AAA', iox
will use it to generate seed key and IV, then encrypt with AES-CTR
So, the *
should be used in pairs
./iox fwd -l 1000 -r *127.0.0.1:1001 -k 000102 ./iox fwd -l *1001 -r *127.0.0.1:1002 -k 000102 ./iox fwd -l *1002 -r *127.0.0.1:1003 -k 000102 ./iox proxy -l *1003 $ curl google.com -x socks5://127.0.0.1:1000
Using iox
as a simple ShadowSocks
// ssserver ./iox proxy -l *9999 -k 000102 // sslocal ./iox fwd -l 1080 -r *VPS:9999 -k 000102
