Saya sudah mencoba untuk setup password-kurang ssh b / w A
untuk B
dan B
untuk A
juga. Menghasilkan kunci publik dan pribadi menggunakan ssh-keygen -trsa
pada kedua mesin. Menggunakan ssh-copy-id
utilitas untuk menyalin kunci publik dari A
ke B
dan B
ke A
.
Kata sandi ssh berfungsi dari A
ke B
tetapi not
dari B
ke A
. Saya telah memeriksa izin folder ~ / ssh / dan tampaknya normal.
A's .ssh
izin folder:
-rw------- 1 root root 13530 2011-07-26 23:00 known_hosts
-rw------- 1 root root 403 2011-07-27 00:35 id_rsa.pub
-rw------- 1 root root 1675 2011-07-27 00:35 id_rsa

drwx------ 2 root root 4096 2011-07-27 00:38 .
B's .ssh
izin folder:
-rw------- 1 root root 884 2011-07-07 13:15 known_hosts
-rw-r--r-- 1 root root 396 2011-07-27 00:15 id_rsa.pub

drwxr-xr-x 8 root root 4096 2011-07-06 19:44 ..
drwx------ 2 root root 4096 2011-07-27 00:15 .
A
adalah ubuntu 10.04 (OpenSSH_5.3p1 Debian-3ubuntu4, OpenSSL 0.9.8k 25 Mar 2009) B
adalah mesin debian (OpenSSH_5.1p1 Debian-5, OpenSSL 0.9.8g 19 Okt 2007)
Dari A
:
#ssh B
bekerja dengan baik.
Dari B
:
#ssh -vvv A

Yang pada dasarnya berarti tidak mengautentikasi menggunakan file /root/id_rsa
. Saya menjalankan ssh-add
perintah di kedua mesin juga.
Bagian otentikasi /etc/ssh/sshd_config
file adalah
# Authentication:
LoginGraceTime 120
PermitRootLogin yes
StrictModes yes
RSAAuthentication yes
PubkeyAuthentication yes
#AuthorizedKeysFile %h/.ssh/authorized_keys
# Don't read the user's ~/.rhosts and ~/.shosts files
Saya kehabisan ide. Bantuan apa pun akan dihargai.
yes
jika tidak, pengguna tidak akan dimintai kata sandi.
PermitRootLogin
pada/etc/ssh/sshd_config
pada A?
