View 4 Replies View RelatedI have many domains on my mail servers using catch-all accounts. Due to this they receive a large number of spam and also the mail queue is always high. As a result, I have been thinking of disabling the catch-all account entirely on all the mail servers. I am however, not sure whether to do it or not. Are there any other companies which have disabled the catch-all facility in their mail servers? Shall I proceed towards disabling the catch-all facility?

Going through [url] Installing_Moodle I came to see the thumb rule of 1GB RAM for 50 concurrent users. While I do not think it is mentioned for VPS, it may imply around 15 concurrent users for 256 MB RAM. A cheap shared hosting can handle that easily without moodle chat. I have heard that VPS is more powerful than typical shared hosting. But, if it is only powerful for the root access but not for handling larger users then it looks like a dilemma situation.
View 5 Replies View RelatedMy client currently have news website that gets around 2.5 million average hits (number of requests) per day. Currently the site is hosted on single enterprise class server in a local data center (in Asia). Some days with breaking news the traffic peaks up and the website become unresponsive for several hours. 60% of the traffic is local and the other 40% is mostly from US and Europe.
My client is on a best available server on his local IDC and the IDC doesn't have anything further to offer, hardware or technology wise. In the same time client doesn't want to drop the local IDC as the 60% of his traffic is local.
What are my options?
1. I'm looking for a multi processor server with 8GB ram/10K 2X400GB SAS HDD's. In general, do I really need this type of server to serve 1 million hits?
2. What type of providers that you recommend for the above requirement?
3. I mainly need to route the US/Europe traffic to a US server or at least blindly route 50% of the traffic to a US server. How do I do this?
-- 3.a. Can this be done with software load balancing or something like Round Robin world work? Or how do we do this?
-- 3.b. What type server Admin's or management providers who can help clients with similar service (see 3.a)?
-- 3.c. Does Cloaking type of thing helps?
how good is adding SPF to a host with catch-all emails in preventing spams. Web hosts suggest to turn off the catch-all emails. But what if there is need to turn catch-all emails, then does SPF record do a good job in preventing hacker from sending out emails that appear to originate our web host?

Recently I've started receiving spam that appears to originate from a hosted domain on my VPS. It appears to only be an issue with this website account and not the VPS generally.
I've disabled the IMAP service to ensure the spam was not being sent from the server. The spam continues which leaves the POP email accounts as a possibility or something else.
My hosting provider says it looks like email spoofing.
Someone seems to be using the address at foobar.com to send out spam. The method that he has employed is called email spoofing. Email spoofing is the practice of changing your name in email so that it looks like the email came from somewhere or someone else. However, you need not be concerned.
Individuals, who are sending "junk" email or "SPAM", typically want the email to appear to be from an email address that may not exist. This way the email cannot be traced back to the originator. The spammer is not using our server to send out spam, hence your email address will never be blacklisted.
There is really no way to prevent receiving a spoofed email. Remember that although your email address may have been spoofed this does not mean that the spoofer has gained access to your mailbox.
The following are headers of two spam emails. Both of these addresses are setup as forwarders and not actual email accounts. The spam came to our attention because it is being sent to addresses on foobar.com with headers as also originating from foobar.com
I changed the actual names for privacy
host.vpsdomain.com [123.123.123.123] - VPS domain
foobar.com - website account on VPS
myemailaccount@gmail.com - address foobar forwarders send to
Delivered-To: myemailaccount@gmail.com .....
It looks like someone spammng from our server. I have checked exim_mainlog and got the this info.

this spammers causing to load cpu very hi and freeze my server sometimes.
is there any way i can setup to only allow authenticated users to access the mail server. or any idea..
im not a hosting company hosting my websites and im a poor guy can't hire server admin.. and i have search it on google could'nt found anything..
I was wondering if anyone has any methods to stop spammers? Currently i am keeping watch on the mail queue and making sure nothing unsual. I have in WHM configuration setup to not allow more 200 mail messages per account per hour but for some reason it will hit thousands. WHMCS does seem to suspend them automatically or maybe its because of WHM BUT only when its too late.
Any thoughts or suggestions?
I have found some spammer hotlinking to my images to get his site crawled, I have modified the .htaccess to attempt and serve his hotlinking domain with a warning but it does not work...
My actual .htaccess file is the one below (it was created by wordpress automatically):
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
I am adding these lines right below:
--------------------------------
RewriteEngine On
RewriteCond %{HTTP_REFERER} ^http://(.+.)?spammerdomain.com/ [NC,OR]
RewriteRule .*.(jpe?g|gif|bmp|png)$ /images/nohotlink.jpe [L]
------------------------------------
My questions...
I dont kmow too much what I am doing, following the tutorial here, http://altlab.com/htaccess_tutorial.html but the problem is that my .htacces already contains something created by wordpress that to me looks like garbage as I don't understand the meaning.
I dont know if I should add the lines inside the <IfModule mod_write.c> or outside them as I have done.
I dont know if it is ok to have two times Rewrite Engine On
PS: When I added the lines I describe above, my site also stopped displaying the images, I had stopped everyone including myself from hotlinking them. I only want to stop certain domain. or even better, my ideal solution is to WHITELIST my domain names (I have two using hotlinkg to those images), but I will settle for blacklist if it is easier.
Have a persistent spammer who kept emailing my clients, even non existent domain accounts and getting the bounced emails to be send to a particular yahoo address. I tried to block in all ways but can't seem to stop him. His spams are from all over the world. Any suggestions?
View 3 Replies View RelatedI was on my visitors on AWstats, and when looking up most of the top IPs (the ones that viewed the most pages), most of them were associated with IANA, and tagged as spam/hacker IPs.
Of course, I've blocked all of those IPs with my .htaccess file, but how can I further protect my server from such threats? How can I rid my server of these spammers/hackers?
Someone posted some code similar to below, I made modifications or two after trying to detect PHP "nobody" users, after dumping a few printenv I found PHP exports PWD when calling an external program such sendmail. Basically the PWD will show the user directory that is coming from, which is enough to detect who is sending SPAM even as nobody! It's not 100% secure in that they could wipe /var/log/formmail but I don't imagine any spam will notice the logger, they presume any cPanel server (or other CP for that matter) is the same.
mv /usr/sbin/sendmail /usr/sbin/sendmail2
pico /usr/bin/sendmail (paste the below code into it)
chmod +x /usr/bin/sendmail
echo > /var/log/formmail
chmod 777 /var/log/formail
#!/usr/local/bin/perl
# use strict;
use Env;
my $date = `date`;
chomp $date;

I wonder if there is anyone else out there who face such problem and how did you stop?
As hosting providers, it is important to follow the standard industry supported AUP/TOS agreements to keep spammers in their place. Do you believe spammers should be able to buy their way to hosting? Some hosting providers have allowed spammers to stay by allowing them to pay a premium hosting fee.

I can confirm that the person who is doing this IS NOT using the 'nobody' user because I am keeping a spam_log for that.
How else is a user able to use our server for spam? Please help as I would like to get this sorted ASAP.
I've been on yet-another crusade this morning..and have a few questions for the..umm.."general" hosting audience.
We live in odd times. If you told me that script kiddies might be able to completely comprimise a server via php..or that spammers are now using the webserver *itself* to send spam a few years ago..I would have laughed. This is no laughing matter.
A concept of privacy comes into play..and I'm curious how many of you handle it. Joe pays me for a account..agrees to my TOS/AUP..and starts uploading files. The way I see it..we have many ways of dealing with scripts that do bad things. It seems to me, though...this may be considered "spying" on our customers.
If we have a script..say..that runs every fifteen minutes..and looks for these scripts..wouldn't that be considered spying?
Or would this be something we should just bury in our aup/tos that this might happen? I have read and agreed to quite a few of those AUP/TOS things..and I can't remember even one time even a mention that files that I upload to the server may be scanned or inspected..before allowing the file to be placved on the server.
Never..not once.
However...this may have changed. If you've ever tried to get even a simple Perl script to work on a Cpanel server...you probably understand that many safeguards are there for the sake of everybody else on the server...and may prevent you from doing what you want to do with the script(s).
At the same time..though..it seems to fly in the face of common sense that many script packages available today are inherently insecure. Chmod 777 files and directories? Even in the times we live in today and know this is a very, very bad idea?
Yet..there seem to be even more like this today than ever before.
>>I mention this from first hand expereince. One of the many magazines I get had a article detailing the trials the author was having trying to get Simple Groupware working on a vps.
yesterday..I noticed a post with a person wanting something installed on a production server. Not only was the program a beta..but..just like Simple Groupware..looked horribly insecure.
In retrospect...I can remember the very first php script I ever used. The year was 1996..and this was my first Cpanel shared account. I even remember having to add *.php to the mime types.
It installed without a hitch..and..coming from the Perl world I had spent many years in..and many hours getting those scripts to work..it seemed almost like a miracle.
It seems, as hosts, there are a few ways we can go at this.
1) Modify the ftp server so it inspects files
2) Have a program that looks for things..much like rkhunter does.
3) A front-end for all scripts..perhaps MySQL as well..that enforces rulesets..for restricted content..or resource allocations.
1. Install CSF
2. Install Iptables if it's not installed (apt-get install iptables on redhat/centos)
3. In WHM under "# ConfigServer Security&Firewall" click on firewall deny ips
4. Open a 2nd window, Goto Main >> Server Status >> Apache Status
5. Check if there are any spammers with lots of connections to a specific file, that's how I got a lot of the IP's.
6. Goto http://ws.arin.net/whois/?queryinput=99.225.243.201
7. Enter the IP you found at "Server Status" and enter it at ws.arin.net to get the proper CIDR which you can easily add to your CSF deny hosts file (which is open in another window)
8. Get a tea and watch the server status closely.
Just got alerted that my server is being used to send spam. Here is the information the datacenter gave me:
[information .....]
NOTE: I changed the real domain name and IP only.
Is there an expert who can help me decipher this? How do I find the culprit? My provider is threatening to shut me down and sink all my clients with the ship!
I am running the latest WHM and cpanel server, fyi.
