SSH 비밀번호 인증 완료


여기에 언급 된대로 ssh 클라이언트가 암호 프롬프트에 액세스하지 못하도록하는 방법을 찾고 있습니다.

password:루트 로그인 프롬프트 를 할 수 없습니다 . sshd_config읽을 파일을 변경했습니다 .

ChallengeResponseAuthentication no
PasswordAuthentication no
UsePAM no

권한 chmod 700 ~/.sshchmod 600 ~/.ssh/authorized_keys. 내가 무엇을 놓치고 있습니까? 암호가 필요합니까?

상세 정보 :

debug1: Authentications that can continue: publickey,password
debug1: Next authentication method: publickey
debug1: Offering RSA public key: /home/user/.ssh/id_rsa
debug1: Authentications that can continue: publickey,password
debug1: Trying private key: /home/user/.ssh/id_dsa
debug1: Trying private key: /home/user/.ssh/id_ecdsa
debug1: Next authentication method: password

/ etc / ssh / sshd_config :

# Package generated configuration file

# What ports, IPs and protocols we listen for

RSAAuthentication yes
PubkeyAuthentication yes
#AuthorizedKeysFile %h/.ssh/authorized_keys

# Don't read the user's ~/.rhosts and ~/.shosts files
IgnoreRhosts yes
# For this to work you will also need host keys in /etc/ssh_known_hosts
RhostsRSAAuthentication no
# similar for protocol version 2
HostbasedAuthentication no
# Uncomment if you don't trust ~/.ssh/known_hosts for RhostsRSAAuthentication
#IgnoreUserKnownHosts yes

# To enable empty passwords, change to yes (NOT RECOMMENDED)
PermitEmptyPasswords no

# Change to yes to enable challenge-response passwords (beware issues with
# some PAM modules and threads)
ChallengeResponseAuthentication no

# Change to no to disable tunnelled clear text passwords
#PasswordAuthentication no

# Kerberos options
#KerberosAuthentication no
#KerberosGetAFSToken no
#KerberosOrLocalPasswd yes
#KerberosTicketCleanup yes

# GSSAPI options
#GSSAPIAuthentication no
#GSSAPICleanupCredentials yes

Subsystem sftp /usr/lib/openssh/sftp-server

# Set this to 'yes' to enable PAM authentication, account processing,
# and session processing. If this is enabled, PAM authentication will
# be allowed through the ChallengeResponseAuthentication and
# PasswordAuthentication.  Depending on your PAM configuration,
# PAM authentication via ChallengeResponseAuthentication may bypass
# the setting of "PermitRootLogin without-password".
# If you just want the PAM account and session checks to run without
# PAM authentication, then enable this but set PasswordAuthentication
# and ChallengeResponseAuthentication to 'no'.
UsePAM no


/etc/ssh/sshd_config

# Change to no to disable tunnelled clear text passwords
#PasswordAuthentication no

두 번째 줄의 주석 처리를 제거하고 필요한 경우 예를 아니요로 변경합니다.

그런 다음 실행

service ssh restart

운영

service ssh restart

대신에

/etc/init.d/ssh restart

이 작동 할 수 있습니다.


이 작업을 자동으로 수행하는 펼쳐집니다.

# only allow key based logins
sed -n 'H;${x;s/\#PasswordAuthentication yes/PasswordAuthentication no/;p;}' /etc/ssh/sshd_config > tmp_sshd_config
cat tmp_sshd_config > /etc/ssh/sshd_config
rm tmp_sshd_config 

다음 단계를 따랐습니다 (Mac의 경우).

/etc/ssh/sshd_config

직원 변경

#ChallengeResponseAuthentication yes #PasswordAuthentication yes

ChallengeResponseAuthentication no PasswordAuthentication no

이제 rsa 키 생성 : ssh-keygen -t rsa -P '' -f ~/.ssh/id_rsa(저를 위해 rsa 키가 작동했습니다. dsa 키가 작동하지 않습니다).

~/.ssh/id_rsa와 함께 생성됩니다.~/.ssh/id_rsa.pub

이제 .ssh 폴더로 이동하십시오. cd ~/.ssh

입력하십시오 rm -rf authorized_keys(때때로 여러 키로 인해 오류가 발생 함).

시작하다 vi authorized_keys

:wq이 빈 파일을 저장하려면 입력 하십시오.

시작하다 cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys

SSH 다시 시작

sudo launchctl stop com.openssh.sshd sudo launchctl start com.openssh.sshd


이것은 내가 가진 튜토리얼에서 가져온 것입니다.

컴퓨터에서 루트로 :

ssh-keygen -t rsa 

암호를 비워 둡니다.

로컬 컴퓨터에서 : (비밀번호를 입력해야합니다)

ssh root@remotemachine mkdir -p .ssh

그때:

cat .ssh/id_rsa.pub | ssh root@remotemachine 'cat >> .ssh/authorized_keys'

이제 pw 프롬프트없이 로그인 할 수 있습니다.

ssh root@remotemachine
