Debian SSHotorized_keys sedang diabaikan

Saya menggunakan otor_keys untuk membatasi perintah yang dapat digunakan untuk pengguna. Pemilik ~ / .ssh dan file tersebut adalah root dan diatur ke

chmod 700 ~/.ssh
chmod 600 ~/.ssh/authorized_keys

Ini bekerja cukup baik, sampai saya menemukan, bahwa pada titik tertentu, pengguna sekarang dapat menggunakan lagi semua perintah File Authorized_keys memang mengandung:

command="mysql -u arg1 -p arg2",no-X11-forwarding,no-agent-forwarding,no-pty ssh-rsa public_key

Saya tidak tahu apa yang saya lakukan salah, saya juga mencobanya dalam mode debug dan memeriksa log. Tapi dia hanya mengizinkan semua perintah.

Login-pengguna harus hanya kata sandi, jadi tidak ada sistem kunci.

Salam ProcTrap

Itu tidak diabaikan secara khusus; klien tidak mencoba otentikasi kunci publik. Perhatikan bagaimana log Anda mengatakan bahwa upaya otentikasi pertama dan satu-satunya menggunakan passwordmekanisme:

debug1: userauth-request for user restricteduser service ssh-connection method password [preauth]
debug1: attempt 1 failures 0 [preauth]
debug1: PAM: password authentication accepted for restricteduser
debug1: do_pam_account: called
Accepted password for restricteduser from XX.XX.XX.XXX port 26048 ssh2

Dan ketika kunci publik tidak digunakan, server tidak memiliki apa pun yang cocok dengan konten yang diotorisasi terhadap ... sehingga tidak menyentuh file itu sama sekali.

Jika Anda ingin menegakkan authorized_keyspenggunaan, matikan otentikasi kata sandi untuk pengguna itu, dalam /etc/ssh/sshd_configmenggunakan Match User ...grup.

Atau, atur perintah paksa untuk pengguna itu, sekali lagi dalam /etc/ssh/sshd_configmenggunakan Match. (Bahkan ada contoh untuk CVS.)
