TightVNC: free, lightweight Windows remote desktop, with encryption behind Pro
TightVNC 4.0.2 is a free, lightweight Windows remote desktop tool with no time limits for personal or commercial use, but encrypted connections require a paid TightVNC Pro subscription at both ends.
TightVNC : Léger, bureau à distance GPL pour Windows et anciens systèmes Unix
TightVNC est une application open source compatible VNC pour un bureau à distance conçu pour un partage d’écran efficace et un contrôle à distance. La branche actuelle 2.x se concentre sur Windows (fonctionne sous Windows XP et versions ultérieures) avec des installateurs pour les systèmes 64 et 32 bits ainsi que du code source sous licence GPL disponible en téléchargement. Les versions plus anciennes 1.3.x offrent un support plus large pour les systèmes de type Unix et les versions Windows héritées.
Caractéristiques clés et performances
- Compression efficace : Un encodage serré réduit l’utilisation de la bande passante, rendant TightVNC adapté aux connexions à faible bande passante et à haute latence.
- Télécommande : Contrôle complet clavier et souris des bureaux à distance pour le dépannage, l’administration et le travail à distance.
- Transfert de fichiers : Le transfert de fichiers intégré entre le client et le serveur simplifie l’échange de documents et de fichiers de configuration pendant les sessions.
- Java et visionneurs natifs : Multiples options de visualiseurs, dont Java viewer pour l’accès via navigateur et lecteurs natifs Windows pour de meilleures performances.
- Disponibilité du code source : Le téléchargement du code source GPL v2 permet l’audit, la personnalisation et l’intégration dans des environnements open source.
Sécurité et licences
TightVNC est distribué sous la licence publique générale GNU (GPL) v2, permettant une utilisation, une distribution et une modification libres sous des conditions open source. Une licence commerciale est disponible pour les organisations qui doivent intégrer le code TightVNC dans des produits propriétaires. Les utilisateurs doivent prévoir des protections au niveau du réseau (VPN, tunneling SSH ou pare-feux de plateforme) lorsqu’ils exposent des services VNC à des réseaux non fiables.
Options de téléchargement et informations sur la version
- Derniers installateurs Windows 2.x : Des installateurs MSI séparés 64 bits et 32 bits sont fournis pour la version 2.8.87.
- Source GPL : Archive source complète en C++ disponible pour les développeurs qui doivent construire ou modifier le logiciel.
- Versions héritées : Les anciennes versions 1.3.10 restent disponibles pour la compatibilité avec les systèmes Windows et Unix hérités.
Outils avancés et écosystème
L’écosystème du projet TightVNC inclut des outils complémentaires tels que MightyViewer, un visualiseur multi-VNC pour Windows qui propose des carnets d’adresses, des aperçus en direct, un support multi-moniteurs et une gestion par onglets pour surveiller simultanément de nombreux postes de travail à distance. MightyViewer est disponible en téléchargement gratuit séparé et utile pour les administrateurs et les classes.
Qui devrait utiliser TightVNC
- Les administrateurs système et les équipes de support informatique ont besoin d’un serveur VNC léger et scriptable ainsi que d’un visualiseur pour le dépannage à distance sur des machines Windows.
- Les développeurs et organisations qui nécessitent un code VNC open source sous GPL v2 ou une licence commerciale pour un usage propriétaire.
- Les utilisateurs opérant sur des réseaux contraints bénéficient des encodages TightVNCs optimisant la bande passante.
