Situation réelle de la question

Dans mon serveur Debian Squeeze, scp y rsync ne semble pas copier quoi que ce soit. Cela fonctionne bien avec un autre serveur (ce n'est donc pas un problème de client). Lorsque l'on utilise scp, il crée simplement un fichier vide et attend. /etc/bash.bashrc contient [ -z "$PS1" ] && return en haut de la page. SSH fonctionne bien. Quel est le problème ?

Inférence : Il ne s'agit pas d'un problème côté client car scp y rsync fonctionne bien avec un autre serveur

Je soupçonne que le serveur qui se comporte mal a des éléments inhabituels dans le fichier ~/.bashrc , ~/.profile ou d'autres scripts. Chaque fois que j'ai vu un comportement similaire, il y avait un logiciel d'exécution automatique sur .bashrc ou quelque chose de similaire.

Il semble qu'il s'agisse d'un une fois par lune bleue bug avec le fournisseur d'accès. Je suis heureux que ce problème ne se soit pas reproduit depuis :-)
