scitex-ssh

name	scitex-ssh
description	[WHAT] Persistent, auto-reconnecting SSH reverse tunnels for NAT traversal — installs an `autossh` systemd unit on the local host so a bastion/relay server can SSH back in even through firewalls and dynamic IPs. [WHEN] Use whenever the user asks to "set up a reverse SSH tunnel", "keep SSH alive through NAT", "access a lab machine from outside", "tunnel through a bastion", "autossh systemd service", "check tunnel status", "remove a tunnel", "expose this machine via a jump host", or mentions bastion server, NAT traversal, autossh, reverse SSH, HPC login node. [HOW] `pip install scitex-ssh` then `import scitex_ssh`; see leaf skills for details.

Installation & import (two equivalent paths)

The same module is reachable via two install paths. Both forms work at runtime; which one a user has depends on their install choice.

# Standalone — pip install scitex-ssh
import scitex_ssh

# Umbrella — pip install scitex
import scitex.tunnel

pip install scitex-ssh alone does NOT expose the scitex namespace; import scitex.tunnel raises ModuleNotFoundError. To use the scitex.tunnel form, also pip install scitex.

See [../../general/02_interface-python-api.md] for the ecosystem-wide rule and empirical verification table.
