Bonjour,

Citation:

Envoyé par pcouas

j'ai copié mon . pub sur le serveur

C'est à dire ?

Et rajoute quelque -v sur ta commande ssh genre -vvv histoire que l'on voit plus de détails sur ce qu'il fait.

Bonjour

j'ai un doute sur les droits et le repertore ou j'ai copie sur le serveur

J'ai également essayer de renommer le id_rsa.pub en  authorized_keys sous /home/git/.ssh sur le serveur avec un chown git et chmod 600 mais sans resultat Idem
Le Pc client est un Windows10

Faut aussi que ton répertoire .ssh soit en 700 .

Et lance la commande ssh avec plus de -v:

Code:

ssh git@127.0.0.1 -vvv -p 2223 -i Z:\zpoubelle\tssh4\id_rsa

Après, il se peut que ta clé privée (id_rsa) ne soit pas prise en compte par le client car celui-ci ne la considère pas "sécure" , par exemple sur ton Z, les fichiers ne sont pas en ton nom ou droit trop permissif.

Mais en principe, on a le message dans le retour ssh...

cool c'etait le chmod sur le répertoore Merci
ssh git@127.0.0.1 -v -p 2223 -i Z:\zpoubelle\tssh4\id_rsa OK

Maintenant je m'attaque au git clone
sur le serveur
git@541a15a5adb5:/srv/git/your-repo.git$
drwxr-xr-x 1 git git 512 Oct 1 17:42 your-repo.git

depuis le PC
set GIT_SSH_COMMAND='ssh -p 2223 -i Z:\zpoubelle\tssh4\id_rsa'
D:\zpoubelle\tstClone>git clone git@127.0.0.1:2223/srv/git/your-repo.git
Cloning into 'your-repo'...
'sshCommand = ssh -p 2223 -i Z:\zpoubelle\tssh4\id_rsa': line 1: sshCommand = ssh -p 2223 -i Z:\zpoubelle\tssh4\id_rsa: No such file or directory
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

Il se peut que cela soit le problème que je soulève sur la clé privée dans mon message précédent, en principe la clé privé sur unix/linux doit être en 400 pour qu'elle soit prise en compte.

Sous windows, je ne sais pas.
