请教：用ssh登录RH Linux AS3空闲后自动断开

small-bird

安装RH Linux AS3以后，用ssh登录后，一段时间空闲不操作的时候，就会自动断开，不知道是什么原因，有没有办法设置，请指教。谢谢。

好像RH8没有这个问题。

这个是很基本的安全设置。
你看一下$HOME/.bash_profile或是.bashrc，看看是不是有TMOUT=...的设置。

1. [root@MyServer root]# cat .bash_profile
   
2. # .bash_profile
   
3. 
   
4. # Get the aliases and functions
   
5. if [ -f ~/.bashrc ]; then
   
6.         . ~/.bashrc
   
7. fi
   
8. 
   
9. # User specific environment and startup programs
   
10. 
    
11. PATH=$PATH:$HOME/bin
    
12. BASH_ENV=$HOME/.bashrc
    
13. USERNAME="root"
    
14. 
    
15. export USERNAME BASH_ENV PATH

好像没有类似的设置。

ssh一会就退出，是件挺痛苦的事.....
