关于ssh公钥登录

小UUUU

想从A登录B

A上ssh-keygen -t rsa
拷贝生成的id_rsa.pub到B /home/aaa/.ssh下
cat id_rsa.pub >> authorized_keys 之后修改了B上的/etc/ssh/sshd_config的相关设置
从A上连接B报“Permission denied (publickey,gssapi-with-mic).”
加-v参数见下

到底啥问题呀 没看出来撒？ 指点一下

$ ssh -l aaa 10.10.115.27
Permission denied (publickey,gssapi-with-mic).
[aaa@CentOS-26 .ssh]$ ssh -l aaa 10.10.115.27 -v

    生成key时候你直接回车默认还是 修改过key  哪保存 ?

     看下log/secure 关于ssh的报错

    bad ownership or modes for file /home/aaa/.ssh/authorized_keys   

    权限错误  

     ll -a     /home/user/.ssh/    列出来     


     对比下我这root的
    -rw-r--r-- 1 root root     authorized_keys

     权限644   属主要对应给用户

   不用什么文档   就是 用A的aaa用户  生成key   pub 到B机器 aaa家目录的 authorized_keys   

   你配置文件都修改什么?

小UUUU

唉 果然是权限的问题 解决了

    error: Bind to port 22 on 0.0.0.0 failed: Address already in use.   

     这个地方有个小报错信息,虽然没影响,但可以去掉  

     你把sshd.config里的   Listenaddress  0.0.0.0 前面的 # 去掉就行!  

     再重启服务就没那提示了!
