配置文件里中括号里面的索引序号应该写多少

lgatuk

有个工程师告诉我配置这个文件：

NOTE:  The changes will last until the next reboot.  For permanent changes,
edit /etc/rc.config.d/nddconf:

     TRANSPORT_NAME[X]=ip
     NDD_NAME[X]=ip_ire_gw_probe
     NDD_VALUE[X]=0

Replace the X in the brackets with the appropriate index, e.g. [0].

最后一句的意思就是 “括号中的X替换为相应的指数,例如[0]。”

请问我的这个配置文档中，我想加入上述工程师说的参数的话，X应该是几呢？ 0？5？

请看我的这个配置文件内容

1. [/]#more /etc/rc.config.d/nddconf
   
2. # nddconf:  network tunable parameters for Streams TCP/IP
   
3. #
   
4. # @(#)B.11.31_LR $Revision: 1.1.119.4 $ $Date: 97/04/23 15:18:44 $
   
5. #
   
6. # Network tunable parameters read in by the networking startup script -
   
7. # /sbin/init.d/net or by executing "ndd -c".
   
8. #
   
9. # TRANSPORT_NAME:     Name of transport component, valid names are:
   
10. #                     ip, tcp, udp, rawip, and arp.
    
11. #
    
12. # NDD_NAME:           Name of ndd tunable parameter
    
13. #
    
14. # NDD_VALUE:          Value for ndd tunable parameter
    
15. #
    
16. # Note: Set all clock time values in milliseconds.  For example,
    
17. #        240000 = 4 minutes
    
18. #
    
19. # Note: The ndd tunable parameters specified in this file must be writable.
    
20. #       "ndd -c" can only handle the write operation.
    
21. #
    
22. # For each additional tunable parameter, add a set of variable assignments
    
23. # like the ones below, changing the index to "[0]", "[1]" et cetera.
    
24. # Index must be starting from 0 and they must be in sequential order.
    
25. # Missing index values inside the array range is not supported.   
    
26. #
    
27. #
    
28. # Example 1: Change the interval for sending the first keepalive probes
    
29. #            for idle TCP connection to one hour
    
30. # TRANSPORT_NAME[0]=tcp
    
31. # NDD_NAME[0]=tcp_keepalive_interval
    
32. # NDD_VALUE[0]=3600000
    
33. #
    
34. #
    
35. # Example 2:  Change the interval for sending keepalive probes to 1 minute
    
36. #             when TCP is detached. (e.g.FIN_WAIT_2)
    
37. # TRANSPORT_NAME[1]=tcp
    
38. # NDD_NAME[1]=tcp_keepalive_detached_interval
    
39. # NDD_VALUE[1]=60000
    
40. #
    
41. #
    
42. # Example 3:  Change the amount of time TCP endpoints persist in TIME_WAIT
    
43. #             state to 30 seconds.  
    
44. # TRANSPORT_NAME[2]=tcp
    
45. # NDD_NAME[2]=tcp_time_wait_interval
    
46. # NDD_VALUE[2]=30000
    
47. #
    
48. # Example 4:  Change the UDP default ttl parameter to 128
    
49. # TRANSPORT_NAME[3]=udp
    
50. # NDD_NAME[3]=udp_def_ttl
    
51. # NDD_VALUE[3]=128
    
52. #
    
53. # Example 5: Change the amount of time that ARP entries can stay in
    
54. #            ARP cache to 10 minutes.

56. # TRANSPORT_NAME[4]=arp

按顺序下来，如果之前没有配过的话，先用0；如果有0和1了，则用2。
