PCM — Python Connection Manager

L'alternativa Linux a MobaXterm — tutto in una finestra: SSH, RDP, VNC, SFTP, FTP, Telnet, Mosh, Seriale.
Scritto in Python con GTK3 e terminale VTE nativo. Funziona su X11 e Wayland senza XWayland.

Versioni disponibili

Versione	Cartella	Framework	Terminale	Wayland	Stato
GTK3	`gtk3/`	GTK3 (PyGObject)	VTE nativo	✅ Nativo	Sviluppo attivo
PyQt6	`pyqt6/`	PyQt6	xterm	XWayland richiesto	Solo bugfix critici

La cartella pyqt6/ contiene la versione legacy (solo bugfix critici); le nuove installazioni devono preferire GTK3.

Protocolli supportati

SSH · SFTP · FTP/FTPS · RDP · VNC · Telnet · Mosh · Seriale · Exec · SSH Tunnel

Funzionalità principali

🖥 Protocolli — tutto in una finestra

Protocollo	Come si apre	Punti di forza
SSH	Tab VTE interno o terminale esterno	Jump Host, X11, Agent Forward, pre-cmd VPN, macro
SFTP	Browser dual-pane integrato	Drag & drop, coda trasferimenti, rinomina
FTP / FTPS	Browser integrato o file manager	TLS esplicito, modalità PASV
RDP	Pannello interno o finestra esterna	xfreerdp3/xfreerdp/rdesktop, multi-monitor
VNC	gtk-vnc nativo o client esterno	Scala, grab input, screenshot
Telnet	Tab VTE interno	—
Mosh	Tab VTE interno	Resistente a disconnessioni
Seriale	Tab VTE interno	Baud, parità, stop bit configurabili
Exec	Tab VTE interno	Qualsiasi comando shell in una scheda
SSH Tunnel	Background gestito graficamente	SOCKS -D, locale -L, remoto -R

🔐 Sicurezza — sopra la media

Password mai sulla command line: PCM digita la password nel terminale VTE quando il server la richiede (feed_child), come farebbe un utente. Nessun sshpass, nessun argomento visibile in ps aux.
Fallback SSH_ASKPASS per OpenSSH ≥ 8.4: se SSH gestisce l'auth prima che appaia un prompt (keyboard-interactive), uno script helper temp mode 0700 passa la password silenziosamente.
Cifratura AES-256 (Fernet + PBKDF2-SHA256, 480k iterazioni): utenti e password in connections.json cifrati con password master. La chiave non tocca mai il disco.
KeePassXC integrato via Browser Protocol v2 (NaCl box): cerca e compila credenziali direttamente dal database KeePassXC aperto — nessun browser necessario.
Modalità protetta: nasconde tutte le password nell'interfaccia.
Gestione chiavi SSH: genera, copia sul server, visualizza la chiave pubblica.
Agent Forwarding (-A): propaga le chiavi ssh-agent per hop multipli senza copiare le chiavi private.

💻 Terminale avanzato

VTE nativo — zero dipendenze X11, funziona su Wayland puro
Split verticale/orizzontale — più sessioni affiancate nella stessa finestra
Temi: Dracula, Nord, Gruvbox, Solarized Dark/Light, One Dark, Monokai, Cobalt, Tomorrow Night e altri
Macro per sessione — comandi inviati con un clic dalla sidebar
Broadcast terminali — invia lo stesso testo a tutti i terminali selezionati contemporaneamente (ideale per cluster)
Multi-exec — esegui un comando su più sessioni in sequenza
Log output su file per ogni sessione (con script(1))
Scrollback configurabile o infinito per sessione
Pre-comando locale: attiva VPN o monta volume prima di aprire la connessione

📁 Gestione sessioni

Organizzate per gruppo con barra di ricerca live
Sezione Recenti in cima alla sidebar: ultime 20 sessioni con timestamp
Quick Connect: utente@host:porta dalla toolbar — si connette senza salvare un profilo
Doppio clic per connettere, tasto destro per menu contestuale ricco
Ping TCP dalla sidebar — verifica raggiungibilità sulla porta configurata (ms)
Duplica, modifica, elimina, esporta script .sh per riaprire da terminale
Import da: Remmina (.remmina), Remote Desktop Manager (.rdm/.json), PuTTY (~/.putty/sessions/), ~/.ssh/config

🛠 Strumenti integrati

Tunnel SSH grafici — avvia, ferma, monitora tunnel in background
Server FTP locale (pyftpdlib) — espone una cartella locale via FTP/FTPS in un clic
Variabili globali {NOME} — riutilizzabili nei comandi di tutte le sessioni
Wake-on-LAN — invia magic packet prima di connettersi
Audit log — storico connessioni con timestamp, durata, protocollo, stato; esportabile CSV
Verifica dipendenze — controlla automaticamente quali tool sono installati

🌍 Internazionalizzazione

Installazione

GTK3 — versione raccomandata

Automatica

git clone https://github.com/buzzqw/Python_Connection_Manager.git
cd Python_Connection_Manager
bash setup.sh

Lo script rileva la distribuzione (Debian/Ubuntu, Arch, Fedora, openSUSE, FreeBSD) e installa tutte le dipendenze di sistema e Python. Crea anche un launcher .desktop nel menu applicazioni.

# Solo verifica dipendenze, senza installare:
bash setup.sh --check

Avvio

cd Python_Connection_Manager/gtk3
python3 PCM.py

Al primo avvio PCM crea connections.json con sessioni di esempio e propone di abilitare la cifratura AES-256 delle credenziali.

🔐 Security — above average

Password never on command line: PCM types the password into the VTE terminal when the server asks for it (feed_child), just like a user would. No sshpass, nothing visible in ps aux.
SSH_ASKPASS fallback for OpenSSH ≥ 8.4: if SSH handles auth before a prompt appears (keyboard-interactive), a temp helper script (mode 0700) passes the password silently.
AES-256 encryption (Fernet + PBKDF2-SHA256, 480k iterations): usernames and passwords in connections.json encrypted with a master password. The key never touches the disk.
KeePassXC integration via Browser Protocol v2 (NaCl box): find and fill credentials directly from the open KeePassXC database — no browser needed.
Protected mode: hides all passwords in the interface.
SSH key management: generate, copy to server, display public key.
Agent Forwarding (-A): propagates ssh-agent keys for multiple hops without copying private keys.

💻 Advanced terminal

Native VTE — zero X11 dependencies, works on pure Wayland
Vertical/horizontal split — multiple sessions side by side in one window
Themes: Dracula, Nord, Gruvbox, Solarized Dark/Light, One Dark, Monokai, Cobalt, Tomorrow Night and more
Per-session macros — commands sent with one click from the sidebar
Terminal broadcast — send the same text to all selected terminals simultaneously (ideal for clusters)
Multi-exec — run a command across multiple sessions in sequence
File output logging per session (via script(1))
Configurable or infinite scrollback per session
Local pre-command: activate VPN or mount volume before opening the connection

📁 Session management

Organized by group with live search bar
Recent sessions section at the top of the sidebar: last 20 sessions with timestamps
Quick Connect: user@host:port from the toolbar — connects without saving a profile
Double-click to connect, right-click for rich context menu
TCP Ping from the sidebar — checks reachability on the configured port (ms)
Duplicate, edit, delete, export .sh script to reopen from terminal
Import from: Remmina (.remmina), Remote Desktop Manager (.rdm/.json), PuTTY (~/.putty/sessions/), ~/.ssh/config

🛠 Integrated tools

Graphical SSH tunnels — start, stop, monitor background tunnels
Local FTP server (pyftpdlib) — expose a local folder via FTP/FTPS in one click
Global variables {NAME} — reusable in commands across all sessions
Wake-on-LAN — sends magic packet before connecting
Audit log — connection history with timestamp, duration, protocol, status; exportable to CSV
Dependency checker — automatically checks which tools are installed
