这是我的拳头帮助，尽pipe是一个每日读者为了学习。
我正在Unix环境（Solaris和Aix服务器）上工作，我的公钥在几个月后突然停止工作。 我试图重新创build密钥，但仍然无法正常工作，下面是我已经完成的步骤：
cd cd .ssh ssh-keygen -t dsa (input nothing on 3 prompts just as did before) cat id_dsa.pub > authorized_keys 之后，我确实发送了所有文件到〜/ .ssh所需的服务器，并validation它在那里。 它没有工作。
我做了一个故障排除和：1.权限是好的：.ssh dir是700; 授权密钥是600（我尝试了许多权限）。 2. sshd_config只有这个条目：
ListenAddress 0.0.0.0 Protocol 2 HostKey /etc/ssh/ssh_host_rsa_key HostKey /etc/ssh/ssh_host_dsa_key SyslogFacility AUTH LogLevel INFO PermitRootLogin yes PrintMotd yes PidFile /etc/ssh/sshd.pid Banner /etc/issue Subsystem sftp /usr/sbin/sftp-server
我试图重新创build这些密钥多次…此外，我已经尝试创buildRSA密钥和authorized_keys2，都没有工作。 好奇的是，这是相同的configuration之前工作。 与其他Unix工具一样，SSH服务由此环境中的系统pipe理员pipe理。 这是我的ssh -vv输出，所以你可以帮助我：

我需要的是login到服务器而不被提示密码。
