Consumes less than 1% CPU and 8MB memory under 800 concurrency.
slaver is single file and only depends on python(2.7/3.4+) standard library.How it works
Access company/school computer(no internet IP) from home
Make private network/site public.
Help private network penetration.
Help CTF offline competitions.
Connect to device with dynamic IP, such as ADSL
Master: Python3.4+, OS independent
Slaver: Python2.7/3.4+, OS independent
no external dependencies, only python std lib

(optional) if you need a single-file slaver.py, run python3 build_singlefile_slaver.py
run these command
# master listen :10000 for slaver, :10080 for youpython3 master.py -m 0.0.0.0:10000 -c 127.0.0.1:10080# slaver connect to master, and use example.com as tunnel target# ps: you can use python2 in slaver, not only py3python3 slaver.py -m 127.0.0.1:10000 -t example.com:80# doing request to mastercurl -v -H “host: example.com” 127.0.0.1:10080# — some HTML content from example.com –# — some HTML content from example.com –# — some HTML content from example.com —
a more reality example:
assume your master is 188.8.131.52 (just like the graph above)
# slaver_local_ssh slaver master(184.108.40.206) You# —- master —-python3 master.py -m 0.0.0.0:10000 -c 0.0.0.0:10022# —- slaver —-python(or python3) slaver.py -m 220.127.116.11:10000 -t 127.0.0.1:22# —- YOU —-ssh 18.104.22.168 -p 10022

ANY service using TCP is shootback-able. HTTP/FTP/Proxy/SSH/VNC/…
shootback itself just do the transmission job, do not handle encrypt or proxy.
however you can use a 3rd party proxy (eg: shadowsocks) as slaver target.
in windows, due to the limit of CPython select.select() , shootback can NOT handle more than 512 concurrency, you may meetValueError: too many file descriptors in select()
If you have to handle such high concurrency in windows, Anaconda-Python3 is recommend, it’s limit in windows is 2048
