SSH masih meminta kata sandi dengan berwenang_kunci

1

Saya mencoba masuk ke server dengan pengguna yang berbeda. Nama pengguna di server adalah gitquery. Saya menggunakan ssh-keygen untuk membuat file-file ini secara lokal: 

/opt/gitquery/gitquery-rsa
/opt/gitquery/gitquery-rsa.pub

Lalu saya menyalin kunci publik ke server: 

scp /opt/gitquery/gitquery-rsa.pub [email protected]:~/.ssh/authorized_keys

Menurut pertanyaan lain di StackOverflow, masalah yang biasa terjadi adalah izin, jadi saya memastikan mereka benar: 

gitquery@someserver:~/.ssh$ ls -al
total 20
drwx------ 2 gitquery gitquery 4096 Jul 27 10:19 .
drwxr-xr-x 4 gitquery gitquery 4096 Jul 27 10:08 ..
-rw------- 1 gitquery gitquery  403 Jul 27 10:07 authorized_keys
-rw------- 1 gitquery gitquery 1766 Jul 27 09:38 id_rsa
-rw-r--r-- 1 gitquery gitquery  397 Jul 27 09:38 id_rsa.pub

Ketika saya mencoba terhubung ke server, masih meminta kata sandi! Inilah keluaran verbose:

Strange: Output verbose mengatakan 'Identifier RSA1 salah' meskipun saya membuat kunci dengan ssh-keygen. Server menerima kunci, tetapi kemudian key_parse lokal mengembalikan kesalahan. Apa yang sedang terjadi?

masalah Anda adalah "Masukkan frasa sandi untuk kunci". Sebenarnya tidak ada yang salah. Pertimbangkan untuk menggunakan ssh-agent atau hapus saja frasa sandi. help.github.com/articles/working-with-ssh-key-passphrases
Chris.C
Anda salah. Seluruh ide di balik file Authorized_key adalah untuk memungkinkan login tanpa kata sandi. Lihat halaman manual ssh, lihat ini: 'Setelah ini, pengguna dapat masuk tanpa memberikan kata sandi.'
digory doo
seluruh ide di balik berwenang_kunci adalah bahwa Anda tidak perlu memasukkan password server , ini berbeda dari frasa sandi untuk kunci pribadi, yang merupakan lapisan keamanan ekstra tapi opsional - dan itulah masalah Anda yang sebenarnya di OP. Silakan luangkan waktu sebentar untuk membaca tautan github lagi.

OKE, kamu benar.

Metode praktik terbaik untuk menyalin kunci publik ke server jauh adalah dengan menggunakan ssh-copy-id. 

ssh-copy-id [-i [identity_file]] [user@]machine

Saya menyarankan untuk menghapus file yang diotorisasi yang dibuat dan menyalin kembali kunci Anda dengan ssh-copy-id. 

ssh-copy-id -i /opt/gitquery/gitquery-rsa gitquery@company

Selama pembuatan kunci Anda hanya perlu menekan enter ketika ssh-keygen meminta Anda untuk kata sandi jika Anda ingin login tanpa kata sandi 

Enter passphrase for key '/opt/gitquery/gitquery-rsa':

Saya memindahkan file otor_keys dan menggunakan ssh-copy-id untuk menginstalnya kembali seperti yang Anda sarankan. File Authorized_key baru dibuat dalam file .ssh, tetapi diff memberitahu saya bahwa file lama dan baru persis sama. Ssh tanpa harus memberikan kata sandi masih tidak berfungsi. :(

Mungkinkah Anda memberikan kata sandi selama pembuatan pasangan kunci? Anda hanya perlu menekan enter ketika ssh-keygen meminta kata sandi jika Anda ingin login tanpa kata sandi Enter passphrase for key '/opt/gitquery/gitquery-rsa':

Ups! Itu dia! Saya konyol! Tulis ini sebagai jawaban, maka saya akan menerimanya ...
