We use the calendar on a site of ours.  For soms reason, this week the site has used 10 GB of bandwidth!!!  This is a VERY small site, that usually has 100-200 visitors per month and uses like 200 MB of disk transfer.  This month 10 GB!!  Checked all formmails - all are okay.  Last resort we are thinking there is a problem with the calendar script??  Logs dont show much of anything weird.  Calendar was installed with latest version about 1 year ago.

Any help or advise is welcome!  Thanks!!

Quite likely someone is hotlinking to images or files on your site. Commonly known as "bandwidth stealing." There are some lines you can add to your top-level .htaccess file to prevent this.

See http://www.htmlbasix.com/disablehotlinking.shtml

Same thing happend to me while ago it turned the calendar folder had been used to install scripts by a hacker.
they had left a file in the calendar folder called updates/pro.pl
I Didnt have the latest update 3.21 installed. I HAVE NOW.

According to my Host This is what the file could do.

"""this program allows the hacker to enter any
shell command they want via a web browser and run it on your account.
This is normally used to download and install other code into your web
space."""

Latest update is 3.21 i would suggest instaling this. and having a Look round your calendar-cgi-bin for any extra files folders.
Let me know if it helped you
bye.

Hello,
I have a user on our server that had this problem too.  The bandwidth sucker was in fact the MSNbot.  For some reason, it crawled the entire calendar everyday; sometimes twice a day.  The user's bandwidth reached the limit quickly.  We used a robots.txt file to prevent the MSNbot from entering the cgi-bin.

Lucky it was a crawler which abides by a robots.txt file!

Web crawlers are also called web spiders from which the name is derived. Spider traps may be created to "catch" spambots or other crawlers that waste a website's bandwidth. They may also be created unintentionally by calendars that use dynamic pages with links that continually point to the next day or year.
