### nmap

for quick scan of available ips 
```bash
nmap -sn ip/24
```
to filter output for open ips 

```bash
nmap -sn 192.168.1.0/24 | grep "for " | awk '{print $5}' > ips.txt
```
scan open ports
```bash
nmap -sCV -A -p $(nmap 192.168.1.155 -p- | grep open | awk -F '/' '{print $1}' | tr '\n' ',' | sed 's/.$//') 192.168.1.155

## TTY Spawn Shell

Often during pen tests you may obtain a shell without having tty, yet wish to interact further with the system. Here are some commands which will allow you to spawn a tty shell. Obviously some of this will depend on the system environment and installed packages.

### Python spawn shell

python -c 'import pty; pty.spawn("/bin/bash")'

Fully Interactive TTY

#### All the steps to stabilize your shell

**The first step:**

python3 -c 'import pty;pty.spawn("/bin/bash")'

Which uses Python to spawn a better-featured bash shell. At this point, our shell will look a bit prettier, but we still won’t be able to use tab autocomplete or the arrow keys.

  

**Step two is:**

export TERM=xterm

This will give us access to term commands such as clear.

  

**Finally (and most importantly) we will background the shell using**

Ctrl + Z

Back in our own terminal we use

stty raw -echo; fg

This does two things: first, it turns off our own terminal echo which gives us access to tab autocompletes, the arrow keys, and Ctrl + C to kill processes

### OS system spawn shell

echo os.system("/bin/bash")

### Bash spawn shell

/bin/sh -i

### Perl spawn shell

perl —e 'exec "/bin/sh";'

### Ruby spawn shell

ruby: exec "/bin/sh"

### Lua spawn shell

lua: os.execute("/bin/sh")

### IRB spawn shell

exec "/bin/sh"

### VI spawn shell

:!bash

### VI(2) spawn shell

:set shell=/bin/bash:shell

### Nmap spawn shell

!sh
