    hi .
    the "View Bandwidth Usage" shows only 300 gig transfer ( BW ) .
    the band admin and Mrtg graph show 1300 gig transfer .

    it means , something is using the BW but not on port 80 !
    @ the reporst of bandadmin , we can see a huge bw usage on the ip , which has no hosts ! (30-50 gig daily !! )
    what can cause the huge bw usage on the ip with no host ? how can i find it ? how can i stop it ?
    thanks :confused:

    Go on, have a guess
    If you have unexpected very high network traffic, then you should check your sever over for exploits, i.e. processes that should not be running, rootkits, etc.

    You'll have to track them down in shell using ps lsof top, etc. If you don't know how to do this, you really ought to find some Linux tutorials and teach yourself, or in the immediate term, hire someone or ask your datacentre to check your server for you.

    There isn't one unless you've installed and configured one.

    That looks suspiciously like a time window when backups would run - you don't FTP your cPanel backups off-server do you?

    You can view users crontabs by looking at the files in /var/spool/cron/*, however you should not edit them directly, always use:

    crontab -e -u accountname
