[Jailkit-users] sftp chroot: Connection closed

[Stefan Reichel \(nmedia GmbH\)]

I installed a sftp jail according to the given documentation.

The only change I've made is, that sshd_config does not permit
PasswordAuthentication, so only publickey authentication is permitted.

Unfortunately, I can't login. The given response of sftp -v address@hidden is

(relevant snippet)
debug1: Next authentication method: publickey
debug1: Trying private key: /home/username/.ssh/id_rsa
debug1: Offering public key: /home/username/.ssh/id_dsa
debug1: Server accepts key: pkalg ssh-dss blen 433
debug1: read PEM private key done: type DSA
debug1: Authentication succeeded (publickey).

I'd be glad to get some help.
