GloMoSim Access Explained
Access to the GloMoSim download page is controlled by an Apache Web Server access list. The Apache server does a DNS lookup on the IP address you are using to access the server. If that IP address resolves to an academic domain name (like *.edu or *.ac.uk) that is in the access list, then the web server grants access to the page. If not, then the server will send back "Access Denied" with your IP address (as seen by the server). You can check what your returned IP address resolves to in both Unix and Windows NT/2000 by executing "nslookup xx.xx.xx.xx" on the returned IP address. Note that firewalls may cause this to be different from your machine's actual IP address.
If the address returned by our webserver DNS resolves to an university domain, then send an email to: firstname.lastname@example.org to ask that this domain be added to the access list.
There is a problem with this method if your university does not export the name of your computer to DNS or the machine is behind a firewall that is not owned (or whose name is not exported) by the university. In this case, you should try to get access to a more central (and thus DNS named) academic computer to access the page. Even with only a shell account and Lynx (text only WWW browser), you will be able to download GloMoSim. Another method of getting access is proving that your machine's IP address is part of an academic IP subnet. This is done by looking up your subnet's IP address in an IP allocation database such as: http://www.ripe.net/cgi-bin/whois or http://www.arin.net/whois/arinwhois.html and again sending an email to:
email@example.com to have your IP subnet added to the access list.
If these methods fail, you are out of luck, sorry.
If you have gotten past the web page access checks, a final hurdle in the registration process is the checking done on the user's email address. In general, we frown upon "Hotmail" type email addresses and thus there are some checks to ban such addresses.
