⚡ SLOPshell

A pure-Python reverse shell generator TUI for CTFs and pentesting.
Zero dependencies — stdlib only. Runs anywhere Python 3.8+ is installed.

---

Features

• Based on https://www.revshells.com/ https://github.com/0dayCTF/reverse-shell-generator
• 40+ reverse shell payloads across Bash, Python, Netcat, PHP, Ruby, Perl, PowerShell, Java, Go, Node.js, Socat, Awk, Lua, and more
• MSFVenom quick-reference commands
• TTY upgrade one-liners
• Auto-detects IP from any network interface (default: tun0)
• One-keypress clipboard copy (xclip, xsel, or pbcopy)
• Persistent config at ~/.config/slopshell/config.toml
• Handles tmux splits and terminal resizes cleanly
• No pip, no venv, no nonsense

Usage

# Interactive TUI
python3 slopshell.py

# Dump all shells to stdout (no TUI)
python3 slopshell.py --list <ip> <port>

# Example
python3 slopshell.py --list 10.10.14.5 4444

Other	Java, Go, Awk, Lua, Socat, Node.js, curl
MSFVenom	msfvenom payload generation commands
TTY Upgrade	Python pty, stty, script, socat PTY pairs

Configuration

SLOPshell reads from ~/.config/slopshell/config.toml on startup.
Press s at any time to write the current session values to this file.

The file is created automatically on first save. You can also create it manually:

# ~/.config/slopshell/config.toml

default_port      = "4444"
default_category  = "All"
ip_from_interface = "tun0"
default_ip        = ""

Options

Key	Type	Default	Description
default_port	string	"4444"	Port pre-filled on startup
default_category	string	"All"	Category tab selected on startup. Must match exactly: All, Bash, Python, Netcat, PHP, Ruby/Perl, PowerShell, Other, MSFVenom, TTY Upgrade
ip_from_interface	string	"tun0"	Network interface to read IP from at startup and on r refresh. Set to "" to disable and use default_ip instead
default_ip	string	""	Static IP used when ip_from_interface is empty or the interface cannot be found. Falls back to 10.10.14.X if both are unset

Interface vs static IP

Using an interface (default):

ip_from_interface = "tun0"
default_ip        = ""

SLOPshell reads the IPv4 address of tun0 on startup and when r is pressed.
Works for HTB (tun0), THM (tun0), or any other VPN interface (eth0, wlan0, etc).

Using a static IP:

ip_from_interface = ""
default_ip        = "192.168.1.100"

The IP is fixed at startup. Use e to change it mid-session, then s to persist.

---

Clipboard Support

Copy works automatically if any of these are installed:

• xclip (X11)
• xsel (X11)
• pbcopy (macOS)

If none are available, the shell command is still displayed in the command box at the bottom of the screen for manual selection.

---

Requirements

• Python 3.8+
• A terminal with at least 80×24 characters
• Linux or macOS (Windows not supported — no fcntl)

tomllib (Python 3.11+ stdlib) is used to parse the config file. On Python 3.8–3.10 the config parser falls back to a simple built-in key=value reader that handles the generated format correctly.

---

Tips

• HTB / THM workflow: leave defaults as-is — tun0 is auto-detected on launch
• After popping a shell: jump to TTY Upgrade category for stabilisation one-liners
• Port reuse: press p, change the port, press s — persisted for next time
• tmux: works correctly across splits and pane switches; the layout redraws on resize
