Block A Range Of IP Addresses?
Feb 27, 2007
Server: OS RHEL 4
Web Server: Apache1.3.37
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 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..

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 try to force delivery and error is:
Message 1Je39R-0000wk-3N is not frozen LOG: MAIN
cwd=/usr/local/cpanel/whostmgr/docroot 4 args: /usr/sbin/exim -v -M
1Je39R-0000wk-3N delivering 1Je39R-0000wk-3N Connecting to italyserver.com

italyserver.com [**.**.**.**]:25 Connection timed out LOG: MAIN
== email@italyserver.com R=lookuphost T=remote_smtp defer (110): Connection
== timed out
--
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

Recently our windows 2003 server, running Microsoft SQL 2005 has been the victim of brute force attacks on the MS SQL admin account. They are unsuccessful, but its annoying all the logged entries in event viewer and the extra stress they are putting on the server asking to authenticate 25 – 60 times a minute.
It comes from the same IP addresses. Is there a way to configure a software fix to block these ip addresses completely from the server? We are running a Hotbrick NAT router, SPI firewall but to my knowledge there is no way to configure an individual IP block with it. Here is link to the specs on the Hotbrick we have:

I am running windows 2003 server.
Recently, there have been brute force attacks to try and compromise my sa password (MSSQL) and root password (MYSQL).
I would like to block certain ip addresses, but looking in the built in firewall in windows I don't see a way to do this. Is this possible with the built in tools/firewall that comes with windows 2003?
If not, can anybody recommend a simple firewall solution that will allow me to block ip addresses? I don't want something that is bloated and blocks popups, viruses, adware, etc. I just want a solution that will allow me to block ip addresses and prevent brute force attacks.

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?

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 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?

Some of our client emails are being blocked and it appears that the whole GNAX range of more than 103680 IP addresses was blocked.
Quote:
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 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?

I've been trying to install a new WHM/cpanel in a clean machine with RAID 1 and in the middle in the install (its a long process as u may know well) throws me some strange messages like this
Apache restart failed. Unable to load pid from pid file and no httpd process found in process list.
If apache restart reported success but it failed soon after, it may be caused by oddities with mod_ssl.
You should run /scripts/ssl_crt_status as part of your troubleshooting process. Pass it --help for more details.
Also be sure to examine apache's variouse log files.

Is there some way to trigger a script or send an email if someone from a specified IP or IP range (e.g. 125.125.125.%) accesses an account, or any URL on the server? Perhaps by placing something within .htaccess or httpd.conf or something of that nature.
For instance, an email "$IP is visiting the URI $REQUEST_URI" would be sent, or a PHP script that sends the email would be triggered (though in that case, I'd need some way to tell the script the IP and URI).
And in a related matter, is there any way (perhaps some existing software) to filter the access logs of an account to find all requests by a certain IP address?

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!
