BFD Events Before Block

Feb 12, 2007

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.

Quote:

REQ="/usr/sbin/sshd"
if [ -f "$REQ" ]; then
LP="/var/log/secure"
TLOG_TF="sshd"
TRIG="10"

WiredTree Review (will Update With Noteworthy Events)

May 15, 2009

I came here about three days ago asking for a good managed dedicated server. WiredTree was mentioned by several people so I checked them out and managed to get a Q6600, 8GB RAM, 2x 250GB HDD's and 4000GB bandwidth for $215.20 per month. Not sure if the deal is still going on or not...anyway! This is my first server so I will try to keep everyone updated as I go through the process.

I ordered the server at about 4AM in the morning and got an e-mail telling me that they'd make a verification call at 9AM-11PM which is when those calls are normally made. I got the call at 9:05AM which is great because i'm used to always being held up by companies making promises then breaking them. The guy on the other end was friendly and asked if I had any questions. I didn't at the time so he told me the server should be up in 12 hours.

13 hours later the server is up and I get my welcome e-mail with all the important login info but I got something else I didn't expect. Actual instructions. Now I know this is a managed server but it still blows my mind that I got a starters guide which explained some of the stuff I had no clue how to do. It saves both my time and the tech supports time. So I dove in and set everything up today when I had some free time. Now i'm just waiting for the DNS to propagate.

In the meantime I decided to upload a file (which it uploaded at maximum speed) and then download that file. It never skipped a beat and I was once again maxing out my cable modem service at 700kbps. Now we will have to see how it holds up once I start having viewers all trying to grab stuff at once but it's nice to know the server is at least performing good right now since i've read some horror stories about people getting super slow download speeds even on dedicated servers with barely any hits.

Well, that's it for now. I'll make new posts when stuff worth mentioning happens. So far i'm satisfied.

Way To Block IP

Jul 8, 2009

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?

Apf To Block An IP Address

Apr 29, 2008

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.

Block An IP Range ...

Apr 6, 2008

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..

Should I Block Yandex

Mar 13, 2008

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

Block A Bot By Netmask

Jan 8, 2008

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 Certain Referrals

Apr 22, 2008

Since yesterday I have noticed some odd activity at one of my websites - www.cartuningcentral.com

The problem is that I am getting huge traffic from what I would say are traffic exchange programs, which I didn't buy, and don't want to have at all.

Examples of the referrals I am getting are:

[url]
[url]

Full details can be found here:

[url]

Now, I have tried to block all those using .htaccess, but I am by no means an expert on that.

Here's what I have done:

RewriteEngine on
# Options +FollowSymlinks
RewriteCond %{HTTP_REFERER} ^(http://)?67.192.42.*$ [NC,OR]
RewriteCond %{HTTP_REFERER} (tserve) [NC,OR]
RewriteCond %{HTTP_REFERER} (trafficserver) [NC,OR]
RewriteCond %{HTTP_REFERER} (67.192.42.2) [NC,OR]
RewriteCond %{HTTP_REFERER} (67.192.42.5) [NC]
RewriteRule .* - [F]
But it's not working at all.

how to block those referrals please?

It can be either using .htaccess, php, whatever.

APF Can't Block Banned One Of The IP

Class C IP Block / ASN

Oct 16, 2007

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.

Block Rapidleech Script?

Jul 29, 2009

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.
