I have a pretty active phpBB forum. I was looking at my stats today and I notice some strange referrals. I checked it out and it and it is a bunch of spam sites. But with a link to one of my threads in the bottom (different per spam site).
- The spam sites have nothing related to my content - The link to the threads in my forum has no relation to each other. - Out of all the sites to put, why mine? My forum is not a very very popular forum.
I can post the link if it will better understand the above situation.
I just like to know why and what purpose does it serve? Also is it bad for me? As it is a spam site is linking to my forum. I dunno if search engines will think my site is a spam site as well.
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
I tried to block incoming referrer traffic from those sites using htaccess but it didn't work , I still see their http request on my server logs and memory keep goes high , am not sure my code is the right
how can I block these http request from these domains , what is the right htaccess code , I use DirectAdmin panel by the way
I'm currently experiencing a lot of IP's starting with 200 and 201 (from Brazil) some IP’s have over 200 connections. I have APF installed and want to know how to block a block on ip's if this is possible. IPS: 200.11.******* 201.*******
Fortigate appliances blocking an IP that is not in RBLs I have a problem with the IP 66.187.108.157 of my VPS it seems to be blocked by Fortigate appliances, as you can see in this error message:
SMTP error from remote mail server after RCPT TO:[url] host mail.am.com.pe [200.62.221.107]: 554 5.7.1 This message has been
blocked because it is from a FortiGuard - AntiSpam black IP address.(connection black ip 66.187.108.157)
However I have searched in this URL [url]and it is clean.
Any ideas on how to have/force Fortigate databases to become updated.
I'm having difficulties with a whm running on centos dedicated server. The problem is that we receive too much of spam and junk emails. by too much I mean 2000 bulks per week. It's killing us.
Is there any way to block a particular ISP? Have a visitor that changes IP hourly, but the IP always resolves back to a hostname like dsl.yuns.sksk.uk .
I have CSF installed. Any way to block all visitors from dsl.yuns.sksk.uk?
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:
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
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?
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
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?
I have spamassassin configured its working 90% but still I am receiving mails from my ID only. Like I have info@domain.com so I am receiving mail from info@domain.com to info@domain.com.
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 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.

I am seeing quite a few hacking attempts coming from the TOR network. I'd like to block the TOR network on the firewall level. Anyone know how to block them?
There is a python script, but I am not familiar with Python at all and do not know how run this script. It is supposed to extract all current IP Addresses and provide a list.
I think they have about 450 IP addresses and I would like to block them.
I currently have a private server in my office which has cPanel and APF installed. The server only allows one static IP to access SSH, at the moment I'm away and don’t have a static IP on my current ISP connection so cannot access SSH.
Is there a way to add say 123.456.000.000 which would allow all IP's in the 123.456 block?
What would you think about creating a big text file with IPs of known hackers, bots and similar "bad" creatures to keep out from our servers? Do you think it's worth it?
Since some days I have a problem with apf: It can't BAN one of the Ip from file deny_hosts.rules. Other IP's are correctly banned. Of course in apf log are:
apf(28474): {trust} deny all to/from 88.84.141.233
but this ip still have access to my server and scan my ports. I have this problem after editing internals/rab.ports (I added some ports to RAB_PSCAN_LEVEL_2). I don't know how can I fix this problem.
Topic should have title: APF can't block one of the banned IP.
I was told by my colocation provider that in order to get a Class C block through them we would have to upgrade to a full rack or get an ASN. At this time, we don't need the full rack space so I guess I have to go the ASN route (no pun intended).
I'm wondering how easy it is to get an AS number and about how long it would take. I did some research on the apnic site and it looks like the cost is $625 per year for just the AS numbers. Is this correct or is there anything else that we may need.
Are there any sites that sell portable ip address blocks like this [url], but for the united states? I can't really read that site, but it looks like for 150 euros a month you can get a 256 portable IP address block. 89.36.148.0/23 seems to be a block purchased from them [url], then routed to AWKnet.
As most hosting company owners know, rapidleech is a very bad script which causes high CPU loads and abuses the server a lot. I do get a lot of abusive users like this on my shared hosting server, running the rapidleech script and abusing the server so much. I have to terminate, at least a few people a day. This is getting to be really annoying.
Is there anyway to block the rapidleech script for a cPanel/WHM server?
I've read that you can do this using Mod Security, but what do I put in my mod security configuration to block it?
Rapidleech is a script that allows anyone to upload the script to a server to download via rapidshare/megaupload to the server, which uses lots of hard drive, CPU, and RAM.
I was wondering we use ConfigServer Security & Firewall for our firewall and was wondering how we can go about blocking certain countries from being able to access our servers, mainly Korea, China and Russia?
On my domain access logs, I see a spammer using many different IPs to join my top site list with fake emails. At the end of every line, it contains I am SPAMER! How can I configure htaccess to block this spammer when a request contains that text?
Hi. I want to block a range of IPs. Currently, I use the following command as an effective weapon against the IPs of people I find in the log trying to do bad things.
/sbin/route add -host x.x.x.x reject
Works like a charm. I then put the offending IP in the file /etc/rc.d/rc.local so that it will reload the bad ips when the server reboots next.
I also use the CSF/LFD firewall, and it successfully blocks single, offensive IPs also.
What I need, though, is the ability to block an entire range of IPs. For example, i have a very persistent hacker trying to access from a certain range like so.... 255.155.x.x.
The last two numbers are always changing but the first two remain the same.
How do I block this "range" of IPs from accessing my server?
Note, I know how to block a range of IPs in a .htaccess file for a certain account, I put this in the .htaccess file...
deny from 205.196.
But when I try this with /sbin/route, it will not accept the ip. My firewall will also not accept a range of IPs.
