为啥新的telnet会话被关掉了？

james5

脚本执行到telnet 然后就退出了

1. 
   
2. #!/bin/ksh
   
3. echo "begin"
   
4. telnet -e ^A $MAILSERVER 25 <<-!
   
5. helo localdomain
   
6. ehlo localdomain
   
7. auth login
   
8. $DEC_ACCT
   
9. $DEC_PASS
   
10. mail from:<[email]xxx@xxx.com[/email]>
    
11. rcpt to:<$rcpt>
    
12. data
    
13. test
    
14. .......
    
15. !
    
16. echo "end"
    

复制代码

执行的结果是

1. 
   
2. Telnet escape character is '^A'.
   
3. Trying 10.1.1.1...
   
4. Connected to 10.1.1.1.
   
5. Escape character is '^A'.
   
6. Connection to 10.1.1.1 closed by foreign host.

修改脚本为如下，还是不行。

1. 
   
2. #!/bin/ksh
   
3. echo "begin"
   
4. telnet -E $MAILSERVER 25 <<-!
   
5. helo localdomain
   
6. ehlo localdomain
   
7. auth login
   
8. $DEC_ACCT
   
9. $DEC_PASS
   
10. mail from:<[email]xxx@xxx.com[/email]>
    
11. rcpt to:<$rcpt>
    
12. data
    
13. test
    
14. .......
    
15. !
    
16. echo "end"

执行结果是

1. 
   
2. Trying 10.1.1.1...
   
3. Connected to 10.1.1.1.
   
4. Escape character is 'off'.
   
5. Connection to 10.1.1.1 closed by foreign host.
