How To Block IP Addresses In Windows 2003 Server - Software Firewall
Jun 18, 2007I 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.
Apache :: Block IP From Accessing A Certain Page On Website
Dec 14, 2014I have the following code in my .htaccess file to block an IP from accessing a file on my site and it works fine.
<Files mypage.html>
Order Deny,Allow
Deny from XXX.XXX.XXX.XXX
</Files>
Is there a way to block an IP from accessing a page (e.g., mydomain.com/mypage/)?
Block A Range Of IP Addresses?
Feb 27, 2007Server: 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.
How To Block All And Allow Certain IP Addresses Range

Dec 3, 2007Recently 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:

Accessing Our Server From Some Locations
Apr 20, 2009Few months back we migrated to a new server (Layered tech Savvis to Databank)
All has been running smoothly, better than before the move.
Over the last week we have had reports from a few clients in various locations across australia and a few in the uk that they can not access the server.
The DNS is resolving correctly for them and traceroutes have not proven anything.
Layered tech have not been real helpful, eventually they put me onto their network department who ran a global test which came back as the server being accessible from everywhere.
The problem appears to be intermittent
Accessing My Server From The Internet
Jul 28, 2008when I install apache on my machine I can open up port 80 on the router and allow outside access.
But, now here is the issue.
I have a p4 server which connects via ethernet to my apple mac. My apple mac connects to the internet via wireless. My apple mac has web sharing activated so the server can access the web. The server has OpenBSD 4.3 installed without X.
What I want to do is get my server online.
It's IP is 192.168.2.4, my macs IP is 192.168.1.1. In the router configuration how would I set it up? Would the router see 192.168.2.4?
Accessing PHP.ini On A Dedicated Server
Jan 10, 2007I'm using a dedicated server for the first time and I want to access the PHP.ini file so that I can set up the mail() function and also enable error reporting.
However, all access has to be done remotely through a KVM console and I'm unsure what I need to do in order to get to the file that I want.
Multiple Server Accessing Files
Mar 28, 2009I have one server right now and will be adding a second server in the next 4-5 months. In the meantime I've upgraded the coding in my community site to act as if there is already two servers. Mainsite.com has all the php files, and a separate HD for mysql db only, [url] has all the user images and videos.
This problem I'm having right now is the permission to delete files from [url]via [url]
What I've Tried:
vsFTPd - it has a small footprint but its not reliable, needed to be restarted a few times while testing on the beta site.
usermod - this is messy, changing chmods, owners, grps... etc I tried all of that but still had problems getting the Mainsite to be part of the group without having to change all the chmods and grps.
NFS mount - haven't tried yet...
Does anyone run a multiple server site? My sites pretty big been around for 4yrs, and i've upgraded servers 3 times since then.
If i can't get this to work right my final option would be to continue to upgrade to a new server each year, everytime a bigger and faster server setup becomes available.
Current server Dual Xeon 5310 4gb, 3 x 146gb scsi/sas. The server is doing fine with this setup. But with the new site uprade and features it's going to top things out. I can keep throwing ram on the server and move mysql off site.
The site has little over 1mil users with about 60-70% of them being active daily...
Remotely Accessing Testing Server - How
Mar 31, 2007id like to set up apache on a spare pc i have lying around, for local dev. id like to stick it in the back of a closet (no screen, kb or mouse) but im wondering how i can best access it from my main computers. is there some kind of decent and preferably free remote desktop application that can be used for this?
i know i can access the xampp installation via the ip address, but inevitably ill also have to access whatever OS i decide to install on it (xp or ubuntu)
DNS Migration: People Still Accessing The Old Server After 4 Days
Apr 3, 2007I migrated my server on friday, and I changed the IP address of my DNS. There are still a few customers accessing the old server. What can I do? Is it possible to flush some persistent DNS cache somewhere?

# Process Tracking. This option enables tracking of user and nobody processes

# further as the script takes no further action. Processes (PIDs) are only
# reported once unless lfd is restarted.

# Port Scan Tracking. This feature tracks port blocks logged by iptables to
# syslog. If an IP address generates a port block that is logged more than
# PS_LIMIT within PS_INTERVAL seconds, the IP address will be blocked.
#
# This feature could, for example, be useful for blocking hackers attempting
# to access the standard SSH port if you have moved it to a port other than 22
# and have removed 22 from the TCP_IN list so that connection attempts to the
# old port are being logged
#
# This feature blocks all iptables blocks from the iptables logs, including
# repeated attempts to one port or SYN flood blocks, etc
#
# Note: This feature will only track iptables blocks from the log file set in
# IPTABLES_LOG below and if you have DROP_LOGGING enabled. However, it will
# cause redundant blocking with DROP_IP_LOGGING enabled
#
# Warning: It's possible that an elaborate DDOS (i.e. from multiple IP's)
# could very quickly fill the iptables rule chains and cause a DOS in itself.
# The DENY_IP_LIMIT should help to mitigate such problems with permanent blocks
# and the DENY_TEMP_IP_LIMIT with temporary blocks
#
# Set PS_INTERVAL to "0" to disable this feature. A value of between 60 and 300
# would be sensible to enable this feature

SMTP Server > ISP's Block
Feb 22, 2008As some of you might already know, many ISP's have been blocking outbound traffic via port 25 to try to lower the amount of spam sent from thier clients.
I am looking for a free smtp server for windows. (This is just for me to use, personal) I would rather run it on my windows server than my linux. I have tried over 7 free ones already including "Free SMTP Server" and after time they have all failed/not worked well/gave errors/and whatnot. Could anyone recommend me a simple smtp server I could run on my windows dedi that also has the function/option to change the incoming/outgoing port from 25 to another #?

Feb 4, 2008I am having a pretty weird problem about ip s at my server. I have a dedi at netdirekt and they gave me like 4 free ips,
all of the sites are at main ip, but today i created a new account and also add 1 of those ips to server and i changed ip of the site.
After that problem started, when i try to ping site it shows ip of the site (new ip), but it gives request timed out. Also sometimes it says, 89.149.218.46 : Destination host unreachable.
If i change the ip of the new site to main ip, site loads well but when i change it to new ip it doesn't load plus gives that ping problem
How Do You Block Multiple Ips In Windows 2003 Server
Oct 30, 2008I found out the ips that were being used to attack my server, but I don't know how to block them. My provider (Limestonenetworks) will not block them from the main router because they don't believe in blocking traffic. Is there a way I can run a firewall that could block the ips? The windows firewall does not have an option to block ips. Last question, if I was to install a 3rd party firewall, it won't lock me out of the server right?

New Server Has Banned IP Addresses
Jul 8, 2008My story starts with my getting burned by fumiNET (the first *grrr*)...
Burstnet reactivates my server (for an additional payment of course). The server seems fine but I thought that I might do better with a BurstNET reseller (better service). So...
I sign up with a reseller, and since I got my new server I've been plagued with email bounces, rejections, etc. Seems that my server (via the reseller) was supplied with a bunch of banned IPs (in other words, crap IPs). (the second *grrrr*)
I've reported to the providers abuse department, but was told that I have to handle this. (third *grrrr* - or is it just continued from the second?)
I've had it. I'm ready to fold up shop. As it is the sites keep me busy - but then...
- I get screwed by fumiNET (losing a big chunk of money)
- the hassle of trying to get my fumiNET server back up (thanks BurstNET)
- transferring to the reseller for better service, and finding out that perhaps BurstNET service was better than the reseller's
I'm open if anyone has suggestions. Some that I've come up with myself...
- finding yet another server provider (recommendations welcome)
- drinking large quantities of Guinness (worth it regardless)
- pulling the plug on the server and getting shared hosting to hold some minimal content
- forgetting the whole damn thing and getting a job as a [pick one]: store clerk, street cleaner, used car salesman
