Tu peux vérifier également que le port 4444 est bien ouvert sur ton client.
Quand la commande autossh est lancée :
% nmap -p 4444 localhost
Starting Nmap 4.62 ( http://nmap.org ) at 2010年09月18日 23:10 CEST
Interesting ports on localhost (127.0.0.1):
PORT STATE SERVICE
4444/tcp open krb524
Si je l'arrête, nmap me dit que le port est fermé. Donc pas de processus fantôme a priori.
Essaye aussi avec la commande ssh simple...
Déjà essayé, pas de différence.
Tu peux lancer ton tunnel avec un petit -v (verbose) pour voir si déjà il te dit qu'il y a quelque chose qui coince.
Ah ouais j'ai oublié de regarder avec l'option de debug (pourtant j'avais pensé à regarder les logs au cas où (rien dans syslog)).
Avec juste -v pas de différence avec une machine où ça marche. Par contre avec -vvv, là y'a des trucs louches effectivement. Regarder surtout vers la fin, après la séquence d'initialisation (dans laquelle je vois rien de spécial, mais que je laisse pour un œil plus averti) quand je demande une page dans firefox et qu'il se produit un timeout.
