openssh改密码认证后

prenewbie · 发表于 2010-10-6 19:08

v版pre 1.45，装了openssh，以前老版本的openssh好像是默认密码登录的，现在要密匙，感觉没必要，又改回密码认证了

配置文件sshd_config改了一下就可以了，但是遇到一个奇怪的问题，每次第一次连接，如果wifi没先激活就用winscp之类的ssh客户端连接，就会出现”不支持的验证方式“的错误，重启关机pre也没用，只有把resolv.conf的nameserver更新了才行，附上我的配置文件，不知道跟设置有关系吗

# $OpenBSD: sshd_config,v 1.80 2008/07/02 02:24:18 djm Exp $

# This is the sshd server system-wide configuration file.  See
# sshd_config(5) for more information.

# This sshd was compiled with PATH=/opt/sbin:/opt/bin:/usr/sbin:/usr/bin:/sbin:/bin

# 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 change a
# default value.

#Port 22
#AddressFamily any
#ListenAddress 0.0.0.0
#ListenAddress ::

# Disable legacy (protocol version 1) support in the server for new
# installations. In future the default will change to require explicit
# activation of protocol 1
Protocol 2

# HostKey for protocol version 1
#HostKey /opt/etc/openssh/ssh_host_key
# HostKeys for protocol version 2
#HostKey /opt/etc/openssh/ssh_host_rsa_key

# For this to work you will also need host keys in /opt/etc/openssh/ssh_known_hosts
#RhostsRSAAuthentication no

# Change to yes if you don't trust ~/.ssh/known_hosts for
# RhostsRSAAuthentication and HostbasedAuthentication

# Set this to 'yes' to enable PAM authentication, account processing,

# be allowed through the ChallengeResponseAuthentication and
# PasswordAuthentication.  Depending on your PAM configuration,

# the setting of "PermitRootLogin without-password".
# If you just want the PAM account and session checks to run without

感觉这个openssh不太稳定，有时候会验证失败，然后造成vpn都工作不正常了

这是我每次刷机后装ssh所用的配置文件,用wqi发到手机上,即可用密码登录.供参考
