Why does this exist?

During a CTF in late 2024, I found myself five SSH tunnels deep while pivoting between hosts trying to find a flag when I suddenly got disconnected from my ssh jump box.

When I finally got back in, all my notes were gone, and I was left with one question: Where My Tunnels?

How does this work?

1. Enumerates active ssh processes using psutil
2. Parses ssh processes into:
   • Master sockets (-MS) and attached socket forwards/sessions (-S)
   • Traditional tunnels (-L, -R, -D)
   • Traditional SSH sessions
3. Find associations between processes, forwards, and connections
4. Detect errors in forwards and connections I.E: a local forward that doesn't have an attached listening connection
5. Render everything in a tree structure using rich

Linux Install

Download the wheremytunnels binary from the release page, see (Which linux binary do I pick?) for help

Then run:

chmod 755 wheremytunnels_latest_linux.bin
mv wheremytunnels_latest_linux.bin /usr/bin/wheremytunnels

Which linux binary do I pick?

glibc vs musl

Nearly all linux systems use glibc or the GNU C Library, including:

• Ubuntu
• Debian
• Fedora
• CentOS / RHEL
• Kali
• Arch Linux

However some more "unique" operating systems rely on musl, notably Alpine linux

Architecture

Most systems run on the x86_64 cpu architecture, however some devices use ARM (aarch64)

The simplest way to tell is by running uname -m, you could also determine this by looking at your cpu specifications

Windows Install

There is currently only an x86_64 install for windows, sorry ARM users

After downloading the windows binary run:

Move-Item -Path "wheremytunnels_latest_windows.exe" -Destination "~/AppData/Local/Microsoft/WindowsApps/wheremytunnels.exe"

Examples

wheremytunnels.exe

wheremytunnels.exe --show-arguments --show-connections
