由于项目的需求,我这边ubuntu下常常需要SSH访问另外一台MACOS。
每次输入密码有点烦,就想到RSA公钥和密钥验证的方法。
像所有教程上讲的一样,本机执行
gong@hzsx:~$ ssh-keygen -t rsa
将公钥拷贝到MACOS的/tmp下,并给其他人以读权限:
gong@hzsx:~$ scp .ssh/id_rsa.pub git@192.168.1.123:/tmp
git@192.168.1.123‘s password:
id_rsa.pub
100% 390
0.4KB/s 00:00
于是登陆了MACOS,这里需要做一些准备工作。
MACOS用户目录下没有.ssh目录。更不用说.ssh下authorized_keys文件了。
dev-mini:~ devone$ mkdir .ssh
dev-mini:~ devone$ sudo chmod 740 /tmp/id_rsa.pub
dev-mini:~ devone$ sudo cat /tmp/id_rsa.pub >>
/home/devone/.ssh/authorized_keys
dev-mini:~ devone$ sudo chmod 740 /home/devone/.ssh/authorized_keys
dev-mini:~ devone$ exit
为了以后ssh访问方便 我在本机添加一个配置文件
gong@hzsx:~$ cd .ssh/
gong@hzsx:~/.ssh$ vim config
添加以下内容
Host dev-mini
HostName dev-mini.local
User devone
IdentityFile ~/.ssh/id_rsa
以后ssh访问MAC OS,我就可以直接
gong@hzsx:~/.ssh$ ssh dev-mini
但是还是让输入密码。
我想应该是MAC OS上sshd_config的配置问题。不是ssh_config哦。
输密码进去
dev-mini:~ devone$ sudo vim /etc/sshd_config
修改后如下:
# $OpenBSD: sshd_config,v 1.89 2013/02/06 00:20:42 dtucker Exp $
# This is the sshd server system-wide configuration file. See
# sshd_config(5) for more information.
# This sshd was compiled with PATH=/usr/bin:/bin:/usr/sbin:/sbin
# The strategy used for options in the default sshd_config shipped with
# OpenSSH is to specify options with their default value where
# possible, but leave them commented. Uncommented options override the
# default value.
# See sshd_config(5) for details on setting the Port and Listen values on Mac OS X
Port 22
#AddressFamily any
#ListenAddress 0.0.0.0
#ListenAddress ::
# The default requires explicit activation of protocol 1
Protocol 2
# HostKey for protocol version 1
#HostKey /etc/ssh/ssh_host_key
# HostKeys for protocol version 2
HostKey /etc/ssh_host_rsa_key
HostKey /etc/ssh_host_dsa_key

StrictModes no
#MaxAuthTries 6

# The default is to check both .ssh/authorized_keys and .ssh/authorized_keys2
# but this is overridden so installations will only check .ssh/authorized_keys

# For this to work you will also need host keys in /etc/ssh/ssh_known_hosts

# similar for protocol version 2

# Change to yes if you don‘t trust ~/.ssh/known_hosts for
# RhostsRSAAuthentication and HostbasedAuthentication
#IgnoreUserKnownHosts no
# Don‘t read the user‘s ~/.rhosts and ~/.shosts files

# To disable tunneled clear text passwords both PasswordAuthentication and

# 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‘.
# Also, PAM will deny null passwords by default. If you need to allow
# null passwords, add the " nullok" option to the end of the
# securityserver.so line in /etc/pam.d/sshd.
UsePAM yes

尤其注意这几个路径
HostKey /etc/ssh_host_rsa_key
HostKey /etc/ssh_host_dsa_key
HostKey /etc/ssh_host_ecdsa_key
中间不是 /etc/ssh/ssh_host_rsa_key
dev-mini:~ devone$ exit
gong@hzsx:~$ ssh dev-mini
dev-mini:~ devone$
终于搞定了。
