新装Centos5.6后ssh登陆不上去

chenyx

正常应该有这样的行

Event Log: Server version: SSH-2.0-OpenSSH_4.3
Event Log: Using SSH protocol version 2

我把原来的设置都清除了，然后用了你的设置,结果就是这样的，刚才登陆一下opensuse，结果如下：（数字码太多，只取了前面的）
192.168.1.106为centos，105为suse

没连接成功.问题出在什么地方呢

chenyx

你对比下centos和suse两个虚拟机与宿主机网络连接的方式看看

还没好.... 哈哈


现在 log/secure  里还显示啥了?   


putty 连接失败后  窗口界面里具体的报错是什么?

zage2004

好像还有port22，不过前面应该已经禁用ipv6了

putty点击连接后，只有一个光标在左上角。没有任何文字
如图：

楼主有没有对比过centos和suse虚拟机的连接方式?

     别的系统能ssh进      

     centos有密钥 的话先 清除掉     

      打开putty 就手动填个...105  IP  然后open登录

    再尝试手动改下 centos  IP    试试

同意,建议楼主先停掉sshd,手动修改下网卡的ip,重启下ssh
