Install AWStats in an ibay, then create a config file for each of the domain names you host, and you can then advise each client of the URL. No password needed.
1) First create an ibay with the name "awstats":
Information bay name: awstats
Description: AWStats Web Statistics
Group: everyone
User access: Write=group, Read=everyone
Public access: (As you like it)
Execution of dynamic content: enabled
2) Download the latest AWStats from awstats.sourceforge.net (
http://awstats.sourceforge.net/files/awstats.zip)
3) Now you have to move the content of cgi-bin directory (wwwroot/cgi-bin) inside the ZIP file into the cgi-bin directory in the AWStats ibay
4) Now you have to move icon directory (wwwroot/icon) inside the ZIP file into the html directory in the AWStats ibay. The icon directory with content should be a sub-dir inside the HTML directory.
5) Now move the content of the tools directory inside the ZIP file into the cgi-bin directory in the AWStats ibay
You now have to configure AWStats.
6) Inside the cgi-bin directory in the awstats Ibay now need to make a copy of the awstats.model.conf file where you replace the "model" with the domain name that you want to get statistics for.
ex. (from Windows/Dos)
C:\>copy awstats.model.conf awstats.www.yourdomain.com.conf
7) Now you have to edit the new .conf file with you favorite editor. Make sure to change the following parameters:
LogFile="/var/log/httpd/access_log"
LogFormat="%virtualname %host %other %logname %time1 %methodurl %code %bytesd %refererquot %uaquot"
DNSLookup=1
DirCgi="/awstats/cgi-bin"
DirIcons="/awstats/icon"
SiteDomain="
www.yourdomain.com" changed to your domain name.
HostAliases="
www.yourdomain.com yourdomain.com localhost 127.0.0.1" changed to your domain name.
AllowToUpdateStatsFromBrowser=1
UseFramesWhenCGI=1 (optional)

Now make sure the the awstats.pl file is an executable. Go to the cgi-bin directory and issue the following command.
[root@e-smith ]# chmod 755 awstats.pl
9) use you favorite browser and open the URL:
http://www.yourdomain.com/awstats/cgi-bin/awstats.pl10) For each virtual domain names, repeat steps 6 & 7, creating a "conf" file for each of the virtual domain names.
11) use your favourite browser and open the URL:
http://www.yourdomain.com/awstats/cgi-bin/awstats.pl?config=www.virtualdomain.com
