一台主机telnet失败

mrsg

一台主机，此前一直都可以telnet登录维护，今早起来连接，出现如下情况
bash-2.03$ telnet 10.10.10.2
Trying 10.10.10.2...
Connected to 10.10.10.2.
Escape character is '^]'.
Connection closed by foreign host

此前都是正常的，从未遇到过这种情况，不知哪位遇到过。

使用ssh同样失败
bash-2.03$ ssh -l root -p 22 10.10.10.2
ssh_exchange_identification: Connection closed by remote host

Do you have access to the console of the server?  Did the server get rebooted recently? It is likely that the server is in single user mode waiting for fsck.

没有重启啊 设备在机房里面，和它同一个机架的设备都正常，应该不是供电的问题

我现在就是没法去机房，所以暂时无法通过console线连接下去

plsease use 'ping' command check the machine netcard status,if it's ok,the server should can normal runing,we need connect console cable login the serve collect explorer,if it's not ok, maybe the server drop to single user mode,

ping是没有问题的，就是去机房太麻烦了

很可能是根或者什么卷满了，导致登陆失败

端口有开，貌似被什么访问列表拒绝了。。。
