Hi all
I'm having problems with a remote connection by sftp. I'm using public key to connect avoiding the passwd request. The correct key is added to the authorized_keys file.
The problem is that the remote host is closing the session. (I'm in charge of the incoming host, a partner in other location is trying to connect to my host via sftp).
I've test with dsa key, rsa key, with different permissions and groups. It was working fine but after add another key for other user connection, it cease to work (all of them).
The vervose of the command is:
/usr: sftp -v msva@10.235.149.12
