Hello,

I have a dedicated server with LunarPages (Dedicated III) with CentOS.

The problem is about bandwidth measurement. I have a vBulletin forum in that server that receives an average of 12,000 visits a day with image attachments hosted in the same server.

Since January or so, bandwidth measured by LunarPages, available at

https://account.lunarpages.com/bandwidth_graphs.php

has been up to 3x more than bandwidth reported by cPanel in my server.

For example, in April:



Red is bandwidth measured by LunarPages, blue bandwidth measured by cPanel.

Visits were constant during those days, but on day 4 I deactivated attachments so bandwidth consumition would go down. It wasn't until April 18th that both measurements were almost the same.

I don't use SCP (Secure Copy via SSH) or download great amounts of data via SSH. I just log once or twice a day on WHM to check server health and sometimes via telnet on SSH, but just for some minutes a day.

I know that bandwidth measured at the network switch port may be a bit higher than the reported bandwidth by WHM/cPanel, it is usually 10% higher, but right now it's 200% higher or more.

My site compresses all .html and .php files with mod_deflate and controls not being hotlinked with .htaccess, so files can only be linked from the domains I have.

I write here because I contacted quite some times LunarPages support about this issue and no one of the support team has given me an answer or solved the problem in the last five months, so I would like to know if someone can help me with this issue. Any ideas will be very welcome.

Thanks for your help and best regards,

Well, I just have an account and a website in that server and I have asked Lunarpages support about giving me a more detailed report about bandwidth consumption and they have not given me any answer.

What I don't like it's that LunarPages haven't offered me an answer about this issue, just vague interest and no detailed information even I have asked quite some times about this.

As far as I know, cPanel measures HTTP/SMTP/FTP/POP3/IMAP Traffic.

I don't have any experience installing a 3rd party script with iptables, could you give me some advice about it, pointing me to a site, wiki or instructions?

Thanks.
