hostA (172.29. 0. 28)
hostB(172.29.0.29)
故障：hostA和hostB同时init 6 重起，过了一会发现hostB已可以连接，但hostA连接不上，从hostB telnet上 hostA的管理IP.

检查hostA的路由表(其实我的环境里不需要检查这一步,因为hostA,hostB 都在同一个网段, 没有这个问题).

参考
总结: 主机通过secureCRT/ ssh 工具无法连接的处理办法:
1) 能否ping通,rsh 上去
2) 通过console连上去检查 df, ifconfig –a输出, /etc/hosts,路由信息(同网段的不需要)
3) 检查/var/adm/message
4) 是否是telnet,rsh服务未启动
5) 如果是telnet,rsh服务未启动, solaris10之前单独用脚本启动, 10用svcs –a 查看, 用 svcs –xv 检查原因(这是最重要的)
附 Solaris 10 x86开启root远程telnet登陆
Solaris 10和后续版本为了保护系统安全，缺省只提供ssh服务，而且还不允许root用户直接登录，这对于开发和调试系统的使用用户来说很不方便。在Solaris 10上开放telnet服务并允许root用户登录的方法如下：
1. 打开telnet服务
# svcadm enable telnet
svcadm是Solaris下最新的网络服务管理系统，要了解它和svcs的使用方法，请参见其帮助手册。
2. 开放root登录权限
修改/etc/default/login文件，注释掉其中的：
CONSOLE=/dev/console
3. 修改root用户的缺省shell为bash
修改/etc/passwd文件，将root用户的shell改为/usr/bin/bash
root:x:0:0:Super-User:/:/usr/bin/bash
不需要重新启动，你再试一试，哈哈，能够telnet登录了吧
