Thanks for reply you are perfect.

I have installed ntop again but I give error messages like below.
What is the meaning of "open of /usr/local/var/ntop/prefsCache.db failed: Can't be writer"
What do I need to do for this problem. mysql or something like that. What did I do wrong? I can't reach admin panel because password isn't compatible. pictures are attached. All of the data is removing when I stop ntop. I think ntop can't write any data in own file. but why?

# [[ $(pgrep ntop) ]] && killall ntop

*try start ntop again
# ntop -d -u ntop -P /usr/local/var/ntop --skip-version-check -L --use-syslog=daemon

* look ntop logs that what happened

Thanks friend. I have controlled files and folders permissions go by /var/log/messages.
I can reach to configuration page of admin site.

*All of data is removed when service is stoped. Could you offer a suggestion about storing information.
*How can I limit to reach http://ntop:3000 page from LAN. I want that only 3 or 4 person can browse this page. Is iptables enough for limiting the users. or .....?
