悲剧啊！winxp宿主机ssh登录不上虚拟机。但是另外一个win虚拟机就能连接上！！

先ping 看看能否ping通

laohuanggua

可以ping的通！

又建立一个ubuntu 9.10 server的虚拟机。发现同样pietty链接不上！！但是这个虚拟机也能ping通。也能上网安装软件。。。。

建议楼主发个/etc/ssh/sshd_config文件看看,不知道你的系统这个东西是不是在这个位置

我估计不是配置文件的事情。---因为我的另外一个win2003虚拟机可以通过pietty登录上。


而是我的宿主机winxp的原因，但是我不清楚到底是什么导致突然链接不上！！能ping通，但是无法sssh登录成功！！！换了putty也不行！！！

你是 宿主机可以 登录到 虚拟的2003 上

感觉是 你 的 ssh 服务没有启动
/etc/init.d/sshd start


然后 ssh 127.0.0.1

[root@jl ~]# /etc/init.d/sshd stop
Stopping sshd:                                             [  OK  ]
[root@jl ~]# ssh 127.0.0.1
ssh: connect to host 127.0.0.1 port 22: Connection refused
[root@jl ~]# ps -ef|grep ssh

root      6048  3614  0 08:59 pts/0    00:00:00 grep ssh


[root@jl ~]# /etc/init.d/sshd start

Are you sure you want to continue connecting (yes/no)?

我在虚拟机上运行
ssh localhost
报告:
connect to host localhost port 22 connection refused

在虚拟机上别ssh  localhost ,直接跟IP看看。看你的本地网络解析localhost 到哪去了，hosts 文件又是怎么写的。你在虚拟2003上SSH能登入这台linux,说明这个虚拟机的SSH服务没问题的。从在里WinXP telnet  虚拟机的IP 22端口看看吧

我在虚拟机上运行
ssh localhost
报告:
connect to host localhost port 22 connection refused

看你配置文件没开localhost端，去掉 “#ListenAddress 0.0.0.0” 这一行的注释，把下面192.168.x.x那行注释掉后重开sshd试试

laohuanggua

感谢各位。我的sshd_config文件应该没问题，要不然就无法从另外的win2003和ubuntu 910虚拟机上ssh过来了。同时网卡也是桥接而非nat的。最后判断是winxp宿主机系统出了问题。


于是我丢掉了用了多年的xp，而改用win7。目前安装的是win7 65907版，已经激活。安装了虚拟机后发现pietty链接成功！！！同时很吃惊的发现，win7下安装的centos5.4，居然默认selinux是没有启动的！！！
