Hello ... I'm trying to use libssh0.4.8 on AIX6.1 and have a problem with public key authentication.
My program simply : - Initialize a session. - Verify the remote server/key matching. - Test if pubkey authentication is ok for the remote server. - Create a private key from the file. - Calculate public key from the private key. - Offer this pubkey to the remote server. - Try to authenticate with this pubkey. And it failed here. After a call to :rc = ssh_userauth_offer_pubkey(my_ssh_session, username, privkey_type, pubkey_string);
rc is SSH_AUTH_SUCCESS. But just after when i try : rc = ssh_userauth_pubkey(my_ssh_session,username, pubkey_string, privkey); rc is SSH_AUTH_ERROR Of course when i try to use ssh to this remote server i can connect.I attached a libssh_trace log part (from the start to the end of ssh_userauth_pubkey call) if it can help.
Any ideas ? Thanks for all Pierre-yves
