HP RP8400 双机热备份，运行SAP，数据库ORACLE。今天突然TELNET,FTP,
CONSOLE LOGIN都不能进入系统，网络正常，SAP GUI能够进入SAP系统，TELNET 时出现信息：
   “Escape character is '^]'.
       Local flow control off
      Connection closed by foreign host.”
这是什么问题，如何解决，请各位老大帮忙，谢谢。

try login with single user mode and check inetd configuration.
If no problems, try:
rm /dev/pty/t*
rm /dev/pts/t*
insf -e

then try again on multi-user mode
