I need to ban IP range and I inserted say ip 12.44.0.0 in the deny_hosts rules, this should ban range from 12.44 but strange is people from that range still be able to access my site, any idea what went wrong?
View 3 RepliesI want to stop users from country X from accessing my website, I know I can ban people's IPs but I dont know if it is possible to ban certain geographical area and if so, I haven't got a clue about how to do it.
View 8 Replies View RelatedDoes anyone know how to range ban IPs using IPsec.
I can enter IPs manually but unable to ban an entire RANGE of ips
i.e. For example 172.10.10.10 - 172.1.1.999
Anyone know?
Do you still have to add each port individually to Server 2008's Firewall like we did on Server 2003?
If so, will the guides that were put out for 2003 work on 2008's? I want to be sure before putting all these ports in....if I can just specify a range instead, it would be much easier!
About a week ago I got logs from the server that looked like this:
unknown (200.87.116.210): 5112 Time(s)
unknown (65.111.177.212): 5005 Time(s)
unknown (bastion.fmg-kopernik.ru): 662 Time(s)
root (bastion.fmg-kopernik.ru): 657 Time(s)
I then turned on the brute force protection cPanel provides, and it went down considerably from there. I'm not concerned at all about it (since the passwords are strong), but I would like to know the best way to determine abusive users (of SSH), and the best way to ban them.
Assuming the server does not have APF installed, or any particular control panel...
Getting these emails, several a day telling me that the server is banning its own allocated IP addresses. Can someone explain what on earth it could possibly be doing to ban its own IP's?

I have centos 4 / cpanel installed with apf / bfd yet the deny host rules for apf does not show the server IP's listed as banned.
How can i ban Yahoo! Slurp and its IPs using .htacces?
View 3 Replies View Relatedý'd want to ban some ip addresses and i tried use iptables. But it doesnt work so far.
what i did is:
root/sbin/ iptables -A INPUT -p tcp -s 193.93.236.0/22 -d any/0 -m state --state NEW -j DROP
as seen, i tried to ban an ip range from my box (coz of spam). But it looks that doesnt work.
What i want to do is to prevent wp spammers to post their disgraceful links to my database.
i am using centos.
my VPS provided didn't enable a lot of modules and that's why I can use a firewall(csf or apf) and dos deflate script
I need a simple script for it.
First,it has to call this:
netstat -ntu | awk '{print $5}' | cut -d: -f1 | sort | uniq -c | sort -n
then there will be something like:
Number : IP address
20 1.2.3.4
40 1.2.3.5
80 1.2.3.6
and then the bash script has to bann IPs with more than 30 connections(In our case: 1.2.3.5 and 1.2.3.6) with this:
iptables -A INPUT -s IP_FOR_BLOCK -j DROP
I installed mod_security and the 403security rules on my VPS (Centos 4.1, Release version of WHM).
Several vBulletin files, including the ajax quick editor and some vbulletin.org add-ons are triggering this rule and banning members' IPs in CSF:
# Restrict witch content encodings we accept.
#
# TODO Most applications support only two encodings for request bodies
# because that is all browsers know how to produce. If you are using
# automated tools to talk to the application you may be using other
# content types and would want to change the list of supported encodings.
#
# Note though that ModSecurity parses only three content encodings:
# application/x-www-form-urlencoded, multipart/form-data request and
# text/xml. The protection provided for any other type of encoding is
# inferior.
#
# TODO There are many applications that are not using multipart/form-data
# encoding (typically only used for file uploads). This content type
# can be disabled if not used.
#
# NOTE We allow any content type to be specified with GET or HEAD
# because some tools incorrectly supply content type information
# even when the body is not present. There is a rule further in
# the file to prevent GET and HEAD requests to have bodies to we're
# safe in that respect.
#
# NOTE Use of WebDAV requires "text/xml" content type.
#
# NOTE Philippe Bourcier (pbourcier AT citali DOT com) reports
# applications running on the PocketPC and AvantGo platforms use
# non-standard content types:

SecRule REQUEST_METHOD "!^(?:get|head|propfind|options)$"
"chain, t:lowercase, deny,log,auditlog,status:501,msg:'Request content encoding is not allowed by policy',id:'960010',severity:'4'"
SecRule REQUEST_HEADERS:Content-Type "!(?:^(?:application/x-www-form-urlencoded$|multipart/form-data;)|text/xml)"
I don't know how to decipher this rule to know if just removing it is ok, or if it is serving an important purpose. During a couple hour period it was enabled, that rule only seemed to trigger false alarms.
The above was triggered with calls such as [uri "/forums/ajax.php?do=usersearch"] and [uri "/forums/newreply.php?do=postreply&t=11057"]
What I really don't understand is that I have an .htaccess in place to turn off mod_security for the /forums directory:
<IfModule mod_security.c>
SecFilterEngine Off
SecFilterScanPOST Off
</IfModule>
I have also had this rule triggered today when someone tried to access : ...
I've been happily banning ip's using the output from
netstat -plan|grep :80|awk {'print $5'}|cut -d: -f 1|sort|uniq -c|sort -nk 1
for over a year now, with iptables. However recently, after upgrading to apache 2.2, the connections in netstat get listed as ipv6. A row can look like this for example:
tcp6 0 0 ::ffff:12.123.123.123:80 ::ffff:12.123.12.:12382 ESTABLISHED-
(actual ip addresses changed)
As you can see, the remote ip address isn't complete, it's cut off, so the script used to sum up connections and insert into iptables isnt doing anything.
Do you recommend a software firewall when behind a hardware firewall?
All of our servers are behind Cisco ASA 5505 firewalls which we rent from Liquidweb. All are being managed correctly and setup to there optimal levels. With hardware firewalls firmly in place, do you still recommend a software firewall such as APF or IPTables (we're talking linux); in our opinion we see it as an extra administration overhead. If this is however untrue, we will change out thinking.
Let's say when i first joined the datacenter, i'm given some 16 IPs from 123.123.123.*.
Now that i need more IPs, and they have to give me IPs from 123.123.124.*, am i right to say i need a new switch?
Now is it possible that i link up the new switch together, so that both switch can pick up any available IPs from either range?
I'm running a web server with mod_evasive and want to know how can I prevent mod_evasive from blocking the googlebot crawler ip address.
Is there a script out there that can detect this crawler and make sure its ip doesnt get blocked by iptables or mod_evasive?
am using APF firewall and am getting ddos from these range ips
4.68.25.*
8.0.4.*
8.0.5.*
how could i delete all the range from these ip's?
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..
we want a dedicated server with a full range of ip with our own company name(or with my name) and abuse mail
+ kvm and apc access
we need a good support too , for example if we want to check our hard disk the provider check it fast

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.
Is there any way to block all and just allow certain IP using APF or iptables?
I want to block all the traffic to the server and just alow IP range.
I have a client who needs to block IP range on a windows server. However, he is using Cloud hosting from Rackspace. I guess they are not being corporative in doing so. Anyway to do this without root? Perhaps from the control panel?
I am getting my quote back Tuesday but need a little bargaining power with these guys...
Oakland, Ca datacenter
40mbps, 20A, 42U rack.
What should I be looking at price range here, how much per mbps?
Only info I've seen is from 2003 where people were saying $200/mbps. Obviously prices have come WAY down. I've seen people on here reselling internap bandwidth for $12/mbps, but they might have bought a huge commit.
i have 2 range ip
range 1 is : 111.111.111-119
range2 is : 222.222.222-229
how may i add both range?
i can add for one range,but about 2 rage i can`t
from 36 hours we have really critical issue:
we have 3 server with Liquidweb that have problem to "resolve" a server locate in Italy
Email sent from server with LW to Italy server is not sent and stay in queue.

We have check, there aren't problem with port and firewall
All seesm ok, for all server
We have try to restart exim, reboot, ..
Emails don't start from 3 server LW to 1 in Italy
We have try to ping from server LW the Italian server and the problem is the same, found IP but 100% packet lost..
If we ping from 3 server LW a IP of server that is "over" the server IT is all ok
The problem seems only with single IP
So, we have try to send from server in Italy to 1 of 3 server under LW.. same problem

I would like to use different Class C IP ranges across my domains for better cross linking. Of course, all domains are closely related to a particular niche.
I am currently on imountain.com, they have been extremely helpful and good. But wondering if same host can provide me different class C IP range?
want to confirm this before i order a new server from them.
or should i just go for another hosting provider? wondering anyone as good as imountain?
Is there any way to get the IP Range of providers like SAVVIS, Global Crossing, or Level3?
View 1 Replies View RelatedSome of our client emails are being blocked and it appears that the whole GNAX range of more than 103680 IP addresses was blocked.

As you should know now: It is not you, it is your complete provider which got UCEPROTECT-Level 3 listed.
Your IP xxx.xxx.xxx.xxx was NOT part of a spamrun, but you are the one that has freely chosen your provider.
By tolerating or ignoring that your provider doesn't care about spammers you are indirectly also supporting the global spam with your money.
Seen from this point of view, you really shouldn't wonder about the consequences.
What I want to know is how often do it happens that a datacenter have all it's IP addresses being blocked?
I contacted Gnax about this but their response was merely that they will take steps and the whole range will eventually be delisted. (Obviously the immediate removal fee of $200 something is too much for them)
Ironically merely a few hours AFTER I contacted them I got a "warning" about spam send from one of our clients.
The date of the email was a few weeks AGO and We already long ago warned our LEGIMATE client that such emails are not allowed and the account will be terminated if it happens again. (In other words WE immediately acted against potential spam while Gnax not and then have the nerve to warn US after WE informed them of the blacklisting)
On the one hand I understand that it can be difficult for a very large provider and uceprotect.net seems a bit harse to block ALL IP addresses due to 0.238 % spam ip addresses.
This came as a surprise today, I setup a server-based RSS reader and could not get WHT's forum RSS feeds. A little digging revealed it was the default APF installation that was blocking the 174.0.0.0/8 range, which includes WHT and a chunk of Softlayer's ip range.
The quick fix is easy, just remove that range from the /etc/apf/internals/reserved.networks file and restart, in the latest apf version, I don't know how many apf versions back this block goes.
The APF folks do a fantastic job in keeping APF up to date, but this seems to be recent update to this particular ip range that hasn't made it into APF yet.
I've found a dedicated server at a great price and plan to stick with it, my first ( already have 2 vps accounts ). I don't have the money for a hardware firewall. However, I do have a chance to renew a Kerio WinRoute Firewall license from way back.
Does anyone think this would be better than the default windows 2003 firewall?
I've read that all ethernet switches in a MST Region need the same Name, Revision number, and list of member vlans for each Instance. So what happens when you need to change the range of VLANs in a MSTI ? Let's say that you need to add a range of vlans to an instance that spans 20 switches? How would you do that?
