How do I block known proxy sites such as anonymouse.org or such via CSF (firewall)? I'll need to block by domains, wildcard domains (such as *proxy.tld) and IP's.
What is the proper way and is there a nice list of such proxies? I'm trying to prevent some degenerate troll from accessing my forum.
I want to block all http requests coming to my website via proxy. Is there any way/script to achieve this on the server?

I need to forward this to an IP address, for example to this address:100.12.33.45/folder.While keeping the original URL (www.xyz.edu/folder). I'm unsure of the apache syntax for this.
Anyone can inform how to fix "http-put proxy" or "http-connect proxy" ?

I am curious, what is the best way to ban certain IP from accessing server? I have software firewall (APF) and there is, of course, /etc/hosts.deny.
Which is the most efficient? I've read that software firewall becomes unstable after so many entries. Does the same apply to /etc/hosts.deny file?
Or is there a better way altogether?
some Chinese forums hotlinking images from my site and I even delete those images they keep sending me huge amount of http requests to my hosting server and eating 800mb of memory and upto 1GB cause server crash

View 9 Replies View RelatedI recently got into a question that how can I use my server to connect to the internet as a proxy server.
I want it to use just for my personal use so don't want to make it a proxy server.
I found out that it's possible to do so with putty and firefox( like this: [url]
but although I tried several times, I was not successful.
Anybody has any way to let me connect to my server to surf the web?
I work for a company who is on Microsoft Technology, IIS 6.0 specifically is what I deal with day to day. We support classic asp 3.0, .net and php ( through plain jane cgi mode *yuck* ) and I am newly hired and bring ruby on rails to the table.
Eventually we are going to replace the entire stack with ruby on rails as I re-code our existing tech. While waiting for IIS 7 to solve the majority of their problems with the lack of MS made IIS modules for rewriting URLs, fast CGI, Server-Side Forwarding I need to get my application out the door and for it to be stable.
Our server is a 2.4ghz Xeon with 512mb and our first order of business is to finally push it to 2g ram. That will help Ruby best as the application is running. What I would like to do is Have IIS sit in front of Mongrel, a ruby HTTP server serving my RoR applications, and pass requests to it.
For example the IIS right now is serving 3 .org/edu sites. We use a company to redirect our URL requests to our IP and IIS has 3 virtual servers passing on the buck all on port 80. It works very well.
I want mongel to sit at, for example, port 8080 and have 1 .org that we serve to use mongrel to serve the content. As I understand it this is called Server-Side Forwording, aka Proxy, and is very ellusive on Windows.
The options I have found is a) the use of Microsoft ISA which is probably out of the question. b) an ISAPI such is ISAPI Rewrite or c) Pound
Our problems arise is that we don't have the ability to toss up another machine for Pound or ISA. Pound can run on CentOS out the box but again, no machine as we are funded by grants, and that will ruin one of the network admins remote desktop uses [so I understand but I could be wrong.]
I have posted on the ISAPI Rewrite forums to see if their 'proxy' feature is indeed what I am looking for. I don't have anything bad to say about Microsoft tech, I enjoy Apache 1x, 2x and have come to respect IIS 6 as well. I just find it hard to find a lot of solid products and documented howto's on MS. One thing I don't find lack of is people with the same darn problem and nobody willing to share solutions exept the ones that are really just technology previews.
So my question is : Has anyone has run across this need and what you did to solve it. Am I on the right track? Again, solutions like mod_proxy for apache isn't an option I need IIS.
Here is the situation:
I'm from a country that block websites! Recently they blocked a useful website that my friends and me can't live without!
We already have a dedicated server (located in the US). We need to do the following:
- register a domain name, and when this domain is requested, requests will be served through our server. That means that our server will get the requested website then delivers it to the user who has requested the website
I know I can simply install a web proxy script such as CGIProxy and use it to surf this blocked website or other blocked websites as well, but that website heavily uses Javascript which I noticed that it does not function probably with scripts such as CGIProxy .
I do not need a detailed HowTo of course, I just need to know where to start from, is this related to some apache option? Do I need some specific software to be installed on server? I need any clue to get me started.
i came across on so many forums and asking a vps that is good for proxy, please state also the standard memory for it...

I have blocked this IP 125.115.144.28
/etc/apf/apf -d 125.115.144.28
But
netstat -anp|grep tcp|awk '{print $5}'| cut -d : -f1 | sort | uniq -c | sort -n
It still showing
202 125.115.144.28
Why?
Is it supposed to blocked right away, or need some time to get blocked.
When I checked /etc/apf/deny_hosts.rules
The IP is in the file.
I set up a forum for a small group of users, so I don't really wish to see spiders or bots on it, so I've put a robots.txt file there to prevent all of them from accessing the forum pages.
I know not all bots follow the robots.txt rule, and these days a really annoying bot called MUNAXNET or Munax AB with IP range 82.99.30.0 - 82.99.30.127 is causing the forum to have extra and unexpected loads.
I've tried to block this IP range with .htaccess and uploaded it to the root of the site a few days ago, here is the content:
<Limit GET HEAD POST>
order allow,deny
deny from 82.99.30.0-82.99.30.127
allow from all
</LIMIT>
However strangely it seems that all of these are not working for this bot, today I saw my forum had 80 users online and that army still keeps coming and browsing all pages of my forums...
I tested the .htaccess with blocking myself, and it actually worked for me, dunno why it's not working for that bot..
I was just researching my log analyzers to see whats happening... I noticed something new in the logs, a large number of unnamed robots or spiders... so I found the robot... it was this:
23310 7.99% 23303 9.48% 1159765 18.56% 22 0.12% 77.88.26.26
After some reading, sites say the ip belongs to spider26.yandex.ru
For simply security reasons, would it be in best interest to block the entire subnet? It seems that the same IP ending in .25 belongs to spider25.yandex.ru
Is anyone using snort?
Does it really block any web based attacks?
I know I can do port scans, and it can alert you to a whole bunch of false positvies, but is it blocking/detecting any serious attacks on your web server?
If so, which rules are the one is alerting on?
I have a Juniper firewall. I'm seeing a ton of traffic from the Twiceler bot in the range of 100,000 hits a day. Luckily they've more recently put up a list of IP addresses their bots use at:
[url]
So, I'm blocking all of these now. However I think it's a simple Netmask issue I'm having. I'm blocking all ports from
208.36.144.0/24
38.99.13.0/24
38.99.44.0/24
64.1.215.0/24
However, I am still seeing the bot in server log files. Could it be that I should not be specifying .0 at the end, but instead .1? Like this in the policy?
64.1.215.1/24

how to block those referrals please?
It can be either using .htaccess, php, whatever.
I Have APF and BFD Installed but it always seems to show 80 odd events before blocking the IP. Is there a way of setting it to say 10 wrong attempts?
I Tried this, but it hasn't done a thing. below happened after the change.
