How I can block other domains that point to my server IP?

[MrTeck]

I found that atleast 2 domains (from china) have an A record that points to one of my server IPs, and I can see at the logs that somebody is scanning it randomly.

....

Can I prevent it with iptables, httpd.conf, named.conf or modsecurity?
I tried with httpd.conf

Code: Select all

Deny from thefakedomain.com

But still showing the default plesk page.

I'm on CentOs 5 with Plesk 10.2

Thanks in advantage

Personally, I use the geo-blocking feature in ASL to just block China completely. I'm not sure if that would solve your problem, but it's something to consider.

[MrTeck]

Well, I can't just block all the country. Have some customers traveling to China and having daily contact with people there.
Thanks for the idea spaceout

[spaceout]

If you have the Firewall module in Plesk or use ASL you could block those IP addresses at the firewall fairly easily using the web interfaces.

In this case its client's that are probably owned by spy/malware and its doing some kind of click-jacking or something. You could always do something clever with mod_rewrite to return those 404 pages to say "Excuse me, you know you're owned right?"... like a public service announcement or something.

[MrTeck]

For me all indicates that is just an A record pointing to my IP
DNS tests online:

dns23.hichina.com. ['119.145.145.59', '218.244.147.146', '218.30.103.224', '222.73.40.39'] [TTL=172800]

MX Records: None
WWW A Record: Your scammerdomain.com A record is: [my server IP]

Imagine I get the domain: thisserversux.com, and with my own DNS I put an A record that points to your server IP.
Is not possible to block the traffic that comes from thisserversux.com?

Well, I will try with modsecurity, but ofcourse could be better if I can block before with iptables.

MrTeck,

Maybe a single Redirect rule at .htaccess (or vhost file) would solve your problem. Something like:

RedirectMatch 301 http://thisserversux.com/(.*) http://myserverrocks.com/owned.html

[MrTeck]

Thanks eduardo.
Finally I created a domain with some adsense banners and with the redirect will get some cents

[scott]

Haha, thats brilliant
