Regarding your second question, uptime does not show the real users logged in, but the total number of pseudo-terminal allocated. That is, if you have more than one open terminal, you will be counted for more than 1 user. You may compare with the output of who to clarify this point.

Colucix,

12:02:09 up 1 day, 9:15, 4 users, load average: 0.02, 0.06, 0.14
[root@oracle d05]# uptime
12:02:59 up 1 day, 9:16, 4 users, load average: 0.05, 0.06, 0.13
[root@oracle d05]# who
root pts/1 Dec 12 10:44 (yusuf.ali.com.kw)
oracrp pts/3 Dec 11 14:10 (yusuf.ali.com.kw)
root :0 Dec 12 10:54
root pts/2 Dec 12 10:55 (:0.0)


uptime shows system is rebooted before 9hours 16 mins.. but I didnt reboot my system .NFS service is also stopped automatically.. but all the remaining applications are running normally ..


Please clear this .

Look at the output of the command last: it will show when a system boot has been done, as in
Code:
reboot   system boot  2.6.22.9-0.4-def Wed Dec 12 09:08          (01:10)
anyway, it will not show who or what triggered the system shutdown (if any). Sometimes shutdowns are related to A/C power losses, and if your BIOS is capable of restore power on A/C return, they will result in system reboots. Could be this an issue for your system?

Colucix,

result as follows :

[root@oracle d05]# last | grep boot
reboot system boot 2.6.9-42.ELsmp Tue Dec 11 02:47 (1+09:35)

system was rebooted at night 2.47 PM ..

I had my telnet session opened all the night and morning I came and accessed it and it was working fine.. I dont know why linux in all aspects sound mystery to me..


Thanks Colucix
Yusuf
