Csf Blocking
Apr 28, 2007At the moment it will block people who login with the wrong username/password 5 times. it also blocks people if they do the wrong email settings.
Is there a way to turn the pop3/email blocking off?

Blocking EV1
Apr 5, 2007I've had it with EV1. On any given day we get 30-50 BFD attacks from their servers. That doesn't include the dozens of other types of attempts per day our IPS/IDS catch. We've also traced back client servers that were hacked directly via EV1 servers.
It's obvious that EV1 does little or nothing to stop these issues. We spoke to the FBI about these issues and their comments lead me to believe that EV1 is one of the major sources of these issues and that EV1 has shown little or no effort to curb the problem or cooperate in stopping the issue.
We have elected to now block all all EV1 IPS.
Drastic measures, not really. If they won't take care of their own problems I no longer want them dumped at my door step. I think other hosts might want to think about this.
POP3 Blocking
Dec 3, 2006I am hitting a limit on number of POP signons per hour imposed by my host. I host maybe 10 domains on this account and have 4 or 5 email addresses to monitor for each domain. If I check once every 15 minutes I run up against a limit on the number of POP3 signons permitted by my ip. Add this to having multiple mail clients behind a NAT router and I am beginning to have real problems.
Does anyone else have this issue? Is my only workaround to forward all email to a single account or install a local mail server? Does 100 POP signons an hour from a single IP sound like a lot to anyone? Any advice?

Blocking A Referrer
Jul 5, 2007seems one of my sites has been added to some mega "toplist" site thats bringing in fake traffic to my site which is basically like a DOS attack - over 1000 connections.
coming from
[url]
[url]
[url]
linking to a php file in one of my accounts which has since been removed. however still getting a heck of a lot of hits, they probably all see 404 messages which still causes load on my server.
any suggestions how to fix this? the traffic is referred from above urls but hundreds of ip addresses. is there anyway to blacklist the referrer so people are just blocked, period?

Apr 14, 2007I had a few sites hacked today. I'm using phpbb (all updates) and, apparently, the only thing they did was to drop the database and replace it with one featuring a single post "advertising" their hacker group. I tried bringing everything back on-line, but they would just attack again and take it down quickly... I'm thinking it's probably just some script kiddies.
They announce themselves as "turkish hackers". Browsing around for their message, I found they attacked quite a few sites. What I was thinking, to help preventing this from happening again, is to ban all visitors from Turkey (none of these sites has a need for them, as they're aimed at a local audience).
Can I do this simply by using "deny from .tr" in htaccess? Or are there any more steps to be taken?
How Can I Tell If My ISP Is Blocking Ports
Nov 7, 2007I have my server set up with the smtp daemon running on port 125, and assp listening on ports 25 and 26, and forwarding to port 125 if the mail passes. This setup has been working for months and months. Already today I've received several emails.
I just attempted to send an email, however, and thunderbird could not connect to port 26. (I use an alternate port because my ISP blocks port 25 except to their mail servers)
So I thought that assp had stopped running. Attempted to go to myip:55555, but the page would not load. Now I really thought assp was broken. SSH'd into server and was able to telnet to localhost, port 26 without an issue. Was also able to lynx [url] without an issue.
Since I'm able to log in to all of these weird ports via SSH but not from my local computer, I'm apt to think that they are blocking the ports (for some reason).
Is there any way I can test this theory? Nothing has changed on my side firewall-wise, and the poor girl at the ISP company didn't even know what a port was. I would like to be 100% sure before I give them another call demanding to speak to someone higher up...

Apf Blocking Allowed IP Addresses
May 24, 2007APF firewall is blocking IP's from the allowed range
I have this inserted in /etc/apf/allowed_hosts.rules and restarted APF of course
67.79.221.0/24

It still blocked this IP for example, 67.79.221.154
Anyone know why?
CSF Firewall Blocking FTP Connections
Jul 11, 2009I have a virtuozzo VPS with CSF. People can't connect to ftp because the firewall is conflicting with iptables. I looked at the csf guide:
[url]
To correct it, the ftp issues states:
Quote:
For example, with pure-ftpd you could add the port range 30000:35000 to TCP_IN
and add the following line to /etc/pure-ftpd.conf and then restart pure-ftpd:
PassivePortRange30000 35000
Where is pure-ftpd.conf? Do I have to install it or something?
Blocking IP Range On Windows

Blocking Access To A Directory
Apr 3, 2009ive got a flash music player that gets its tracks from a dedicated directory on my server. there's about 10GB of music in there (we own it) and i want to stop people getting at the files (they can see the path in the source of the page that has the flash player).
i tried an htaccess directive that stops listing the directory contents but that obviously wont work. what is the best & most secure strategy to achieve this, blocking all ip addresses apart from my server's?
Blocking Entire Countries In IIS
Jul 23, 2009I have come across an issue where traffic from India is hurting my business. What I have is a number of job boards. Realistically, the only issue I am having is with IT and Engineering positions being applied for heavily by people in India. Since my customer base is all in the USA, I would like to just block India.
While I know this is easy with Apache using a .htaccess file, I am using IIS on server 2007. Does anyone have any idea on how to do this easily with the large number of IPs that India uses?
Server Email Blocking <?>
Mar 9, 2008I recently signed up a new client to my dedicated server - The minute they switched over to my server, it seems that all hell broke loose. (I'm going to refer to them as "Company A")
Company A called me up and said that one of their employees was getting a huge amount of SPAM and that after a day or two, they were having issues with their E-mail.
I looked at my logs and it showed something unusual-
LOGIN FAILED, user=myclientuser@companya.com, ip=[::ffff:XX.XXX.170.47]: 110 Time(s)
When I explained this to Company A, they ran some virus checks on their computers and 3 out of 5 computers had viruses on them.
They claim to have fixed the viruses but now, they cannot send e-mails to specific clients.
I checked their I.P. against blacklists and they are using Comcast cable internet at their location and I cleared their only blacklisting (spamhaus.org).
I'm still getting calls that Company A cannot e-mail a few of their clients and just to make sure it's not JUST them, I tried to send a test e-mail to the same clients as Company A.
The e-mails from me were rejected due to time-out.
HERE IS MY QUESTION:
Is this an issue on MY end that must be taken care of *OR* is it due to the fact that they had viruses on their computers and now they are blocked because the virus tried to attack everybody in THEIR e-mail address book?
None of my other clients are complaining of e-mail issues or that e-mails are getting kicked back. Just Company A.
Weird Example Of Blocking Port 25
May 6, 2008I have a client who was sending email to another server with Cpanel, all of a sudden all emails are in the queue for a few days and we checked everything was ok on our side even the logs are able to find the domain name, just that it drops from there.
Took me a while I finally telnet their port 25 and found it block, but somehow a few minutes later it was unblocked. Is there any mechanism in Cpanel that auto block port 25? I know the client uses a catchall so all rubbish went there, I cleared the catchall for him.
MSN / Hotmail Blocking Messages
Feb 13, 2007It appears that MSN / Hotmail have recently began blocking an awful lot of servers I manage. Several of them (for a company I work for) are in a few blacklists however a number of the IP addresses I manage are 100% clean.
Anyone know of something MSN/Hotmail recently began enforcing?
The blocks began at around 6 PM EST on Thursday of last week.
The error message is as follows:
Your e-mail was rejected for policy reasons on this
gateway. Reasons for rejection may be related to content such as obscene
language, graphics, or spam-like characteristics (or) other reputation
problems. For sender troubleshooting information, please go to
http://postmaster.msn.com. Please note: if you are an end-user please
contact your E-mail/Internet Service Provider for assistance.
I feel like a pawn for asking this on WHT but from what I can see
it's fairly widespread.
The domains in question do have basic SPF implemented as well.
not limited to a contact at hotmail / msn that would enjoy a phonebeating.
Blocking Mails With Certain Subject
Nov 5, 2007I would like to block emails that contain certain subject that goes to one domain and also the one being sent internally between the users on the same domain. The tricky part is, the recipient of the blocked email will receive a notification (The message has been blocked. To retrieve the full emails, please contact the administrator). Anybody has done it before?

APF Blocking Legit Users
Aug 21, 2007This is just a notice: one of the staff of a large site I run was no longer able to log into the site. As it turns out his IP was being blocked by APF.
The reason for his IP being blocked was that it ended in 255 (x.x.x.255). Any such addresses are blocked by the PKT_SANITY_STUFFED option, which is turned on by default in recent versions of APF. When restarting APF this option shows up as {pkt_sanity} deny all to/from 0.0.0.255/0.0.0.255 and can be seen under "OUT_SANITY" when doing "apf --list".
As you notice the problem is that some ISPs are are assigning supposedly "bad" IPs ending in 255 to users. And I'm not the only one hitting this problem either: [url]
If you are also using (a recent version of) APF, you might want to turn this option OFF.
In the meanwhile, if anyone is so enlighted... why was this option in APF in the first place? What so bad about IPs ending on 255? The APF docs say they're bad broadcast addresses, so why are ISP assigning them anyway? Who is at fault: APF or ISPs?
Mod Evasive In Apache2 Keeps Blocking Me

My ISP Is Blocking Ports From 2082+

What Else Would Be Blocking HTTP Requests
Jan 19, 2007I have a guy who can't get to any of the 100 or so virtual hosts on my RHEL3 server.
It's running the latest Apache RPM from RedHat. I also have mod_evasive and mod_security running.
Here's what I know. The guy *CAN* connect via SSH and FTP. The guy *CAN* see the default web page when he hits the IP in his web browser (e.g. he types [url]into the address bar on IE). But when he uses any of the host names on the server he *CAN NOT* see anything. He gets timeout errors.
His IP in NOT in ANY error logs, it's not in mod_evasive or mod_security, it's not in IPTABLES, it's not anywhere I can see.
I must be missing something. Anyone have any ideas?
What would be in front of Apache blocking his requests?

Oct 3, 2007when I enable csf my server looses the ability to do an nameserver lookups. It doesn't seem like port 53 is being blocked, I've added the 2 nameservers in /etc/resolve.conf to my csf.allow file, but still nothing. Outgoing mail fails because it can't lookup domain names, I've tried nslookup from the command line and it times out. I'm out of ideas. Am I wrong about looking at port 53?

Apache :: Configuring IP Blocking?
Apr 7, 2014I've been trying to figure out some IP blocking with no success. The environment is UNIX and Apache version is 2.2.22-14.
The site is on a hosted solution and doesn't have a firewall due to the virtualization software limitations. I've tried setting something similar to the following:
Code:
<Directory /home/username/mysite.com>
#IP Blocks
Deny from 1.2.3.1/24
Deny from 1.2.4.5
etc..
but with no success. I've also tried it in the <Location> tag with no success.
The way I'm testing this is editing the conf and then bouncing the apache server.
Yahoo Is Blocking Our Domain Name Emails
Apr 20, 2009We are only a small construction business in NEW Zealand, and send very few emails. But from the 4th April, Yahooo has started blocking all emails from our domain name?
We hve not done bulk newsletters, we have not had bulk reject messages. Our website/ email host is Clevernet.
YAhoo NZ have sent us a bulk email form, which Clevernet submitted. We then had to get another approved server form filled out by Cleverney which they did last Friday, but our email domain is still blocked.
Xtra/ Yahoo NZ< seem to think there is nothing they can do, but wait and see if Yahoo unblock it. There does not seem to be anyone who we can contact at the Yahoo server. NZ say they cant contact anyone at Yahoo. We seem to be stuck between a rock and a hard place.
