XRDP ne fonctionne pas sur eole 2.8
- La connexion dépanneur => XRDP fonctionne
- Un netcat permet de se connecter au poste depuis le conteneur XRDP :
- Côté client :
netcat -l 0.0.0.0 5900 - Côté serveur :
echo "a" | netcat -N 10.20.26.165 5900 - Résultat
aapparait sur le client
- Côté client :
- Mais la connexion XRDP => X11VNC plante avec l'erreur suivante
- Sur le poste dépanneur
- Sur le serveur, si on lance
xrdpà la main, on voit les logs suivants :
