Yes it is exactly as I put it in. The port number might be the issue then, some example I saw used the IP twice. I cannot seem to find the port number for this website though. I'll try to find it and try again. Thanks.

Is this the rule exactly as you put it in?  You have the ip in twice and it should be 'ip<space>port'   where port is probably [80,443] depending on how you access the site.

Thanks for the input, Ed. I have tried what you suggested.

I made a new rule based on the rules already present:

"alert tcp any any -> 173.254.252.81 173.254.252.81 (msg: " **Alert gtx0.com has been opened**")"


(IP used above is the one for www.gtx0.com)

I used command "snort -d" and opened up gtx0.com in a browser but no notifications or logs were given. Any further tips, anyone?

Here's a quick and dirty way. You can take another rule and copy it. Then you have to pick a Sid that's not in use. 

Change the msg content to the URL. 
If you create a new rules file, you will have to include it in your snort.conf. 
If you using something like barnyard2 there's more to do.  

Cheers,Ed

I am quite new to using Snort. 


I was hoping to get pointers on how write a rule to get notification
if a certain website, like say www.facebook.com, is opened in a web browser, and how would I get this notification/alert to show.
