Howto Implement A Spam Appliance Correctly

May 14, 2009

We are planing to implement a spam appliance like the mailfoundry for our 60 cpanel servers.

What is the best and easiest way to replace the standard cpanel mx entry in the dns zonefiles with our two new MX entries?

Additionaly we need to enable the option "Always accept mail locally even if the primary mx does not point to this server." for all the dnszonefiles where we use the new MX entries.

The problem is, that some customers are using already own mx entries, therefore we can not change all of them, but only the entries which point to the cpanel server.

Does someone have a script for this, or how would you change this?

Anti-spam Appliance - Barracuda, MailFoundry, Etc.

Jul 31, 2009

Does anyone have any experience to share concerning these devices?

I'm having some serious spam issues and would like to look into a better approach to preventing this than the typical SpamAssasin solution bundled with cPanel, Plesk and so on. SA seems rather inefficient, needs a lot of training, can get a lot of false positives, tends to break now and then, and so on.

Have any of you used either the Barracuda or the MailFoundry applicances, or even better - compared them first hand? Are there any similar solutions out there, perhaps cheaper/more cost effective in the long run?

$2000-3000+ for the hardware and around $500 a year for an anti-spam solution is a little steep in my opinion. Especially considering the old and cheap hardware for an example MailFoundry uses. How accurate they actually are in terms of false positives is also seemingly debated. MailFoundry promises a near 0 false positive rate, while some user-experiences suggest somewhere between 6-10% - which could represent an issue just as problematic as spam itself. Nobody wants to lose out on important email. To spend such an amount on a device and updates, it certainly needs to be worth it. Is it?

Are there any equally good or better software based solutions out there, that one could for an example use to set up a custom anti-spam server using existing hardware at the DC?

Plesk Automation :: Use Mail Node With Spam Filtering Appliance

May 20, 2014

We want to configure our PPA mail node to send all outbound mail through our spam filtering appliance but don't know where to start.

Reading standard Postfix docs give basic instructions on how to direct a handful of domains through a mail relay but we want to direct every outbound email from all domains through our spam filter.

We also want to ensure that any regular updates to the mail node won't break or undo this config.

Jan 29, 2008

i am having a complete nihgtmare trying to implement ssl on my website.

I have ports forwarded on my router for 80 and 443 to my webserver and i can always access my website when i do not have ssl activated. When i do activate ssl though i get the message saying this site must be used using a secure channel which is ok but when i enter [url] i just get a message saying page cannot be displayed.

I have installed a certificate and i think it is correct. I am not even be able to access it internally on my intranet.

How To Safely Implement 301 Redirects On A Shared Windows Server

Oct 3, 2007

Have done some searching as to how I might do this. On a Unix server it's no problem, .htaccess and away we go. However I want to set up a stack of redirects on a shared Windows server, without causing any issues.

The shared server has many of our clients so we can't do anything too 'risky'. This includes a global.asa, or messing with the IIS settings via remote desktop.

It is too late to reuse the old file paths, besides they were not seo-friendly.

This leaves simply retaining the old files and putting asp 301 scripts up top of each page. Fair enough, but it still leaves a mess on the server - ideally I want just the new files in there.

The vast majority of the old pages are actually just HTML, there's only a couple that were .asp (contact forms etc). Does that open up any options? PHP doesn't appear to be enabled as of now, but apparently could be.

Apache :: Configure And Implement Server With Ssl Using Ldap For Authentication

Apr 28, 2015

I have a class project that we are working on where we have to configure and implement an Apache server with ssl using ldap for authentication. I have documentation of literally everything I have done in the configuration. Everything seems to be fine with the config that I can tell. The client gets a prompt for username and password when they access the server ip address. However, once the correct username and password are entered, then the client receives a 500 internal server error message instead of the webpage: "Internal Server Error...The server encountered an internal error or misconfiguration and was unable to complete your request.

Rackmount AntiVirus Appliance?

Apr 25, 2007

Can anyone recommend an affordable antivirus hardware appliance that can be put in-line between a physical machine acting as a mail server and the switch? I need it only to filter on ONE machine so it would not have to be extremely fast. Spam filtering would be a plus as well. Any recommendations? I am looking for something plug and play.

Bring Web-filtering Inhouse - Appliance / Application

May 1, 2008

I have a requirement to bring web-filtering inhouse on our own hardware.

This is to support up to 50 remote sites - I've looked at iron port / barracuda but Im not sure if it can do what is required.

I need each remote site to effectively have a seperate 'account' with the ability for each sites manager to see the traffic just for their site, create users for that site, specify site specific blocks / allows and also monitor which users are browsing which sites.

Does anyone know of a product or application that allows this sort of segmentation? I'm not a big fan of Surf Control (I don't believe it's able to deal with this sort of setup)

The other option is 1 appliance per remote site - but the costs associated with this are probably out of our budget for this project.

This one's an itnerestign one thats been bugging me for a while!

Great Success !
Apache is working on your cPanel® and WHM™ Server
If you can see this page, then the people who manage this server have installed cPanel and WebHost Manager (WHM) which use the Apache Web server software and the Apache Interface to OpenSSL (mod_ssl) successfully. They now have to add content to this directory and replace this placeholder page, or else point the server at their real content.

HowTo - Bouncing Of Dedicated

Jun 13, 2007

I'm on CentOS 4.4, webmin, LAMP, OpenSSH and ProFTPD server.

But what I'm wondering is how to look at my off network backup space.

I can only access my backup space through the DC network/my own server. So I need some kind of way to bounce a GUI ftp connection off the server - which would allow me to look at the files...

I know I can use rsync for backing up and restoring. But the way I understand rsync I need to know exactly what I am to move, as it operates on an exact command.

Howto: ASSP Installation In CPanel

Jan 29, 2007

What is ASSP? ASSP is an Anti-Spam SMTP Proxy . The homepage can be found here. ASSP is a lightweight daemon that can filter mail based on various things such as SPF, RBLs, Bayesian word lists, as well as blocking email addresses from getting mail, or having mail filtered.

This tutorial will walk you through getting the admin interface for CPanel setup for ASSP. Currently, a paid user interface can be obtained here (note that I am in no way affiliated with, nor have I tried to use this UI, I am just offering the link to those that might find it useful)

Firstly, the setup:
You will need to activate Cpanel PRO (pro.cpanel.net/activate) for your server in order for this to fully work. This activation is currently free. Simply go to the previous mentioned URL and enter your IP address if you have not done so already.
Once you have activated CPanel PRO, go into whm->addon modules and check clamav connector, then click on "save". This will install clamav for you to use
Once you have done THIS, go to whm->service manager and UNcheck spamd (it is no longer necessary with ASSP), and again click on save/submit. Note that this IS optional, however the purpose of ASSP is to defeat spam before it GETS to SpamAssassin.
Once you have done THAT, go into whm -> tweak settings and uncheck SpamAssassin and BoxTrapper mail.

Secondly, the requirements:
ASSP needs certain perl modules established To install these, simply login (as root) to your server, and type the following

Code:
/scripts/perlinstaller --force Compress::Zlib
/scripts/perlinstaller --force Email::Valid
/scripts/perlinstaller --force File::ReadBackwards
/scripts/perlinstaller --force File::Scan::ClamAV
/scripts/perlinstaller --force Mail::SPF::Query
/scripts/realperlinstaller --force Mail::SRS
/scripts/realperlinstaller --force Tie::RDBM
/scripts/realperlinstaller Sys::Syslog
/scripts/perlinstaller --force Net::LDAP
/scripts/perlinstaller --force Time::HiRes
/scripts/perlinstaller --force Tie::DBI
Note that the --force is optional, however it will make sure you've got it installed. Do these one at a time as some of these have configurable options to them.
One more perl module is needed. Since the later versions of Net::DNS are known to cause issues with RBLs, SPFs and the like, it is advised to use 0.57 . This can be obtained by doing the following:

Code:
mkdir /usr/local/assp
cd /usr/local/assp
mkdir /usr/local/assp/tmp
cd /usr/local/assp/tmp
wget [url]
tar xzf Net-DNS-0.57.tar.gz
cd Net-DNS-0.57
perl Makefile.PL
make
make test
make install
Do NOT remove the /usr/local/assp/tmp directory as when you update cpanel, it will try to auto update Net::DNS again, so you will want this intact.

Now, let's get with the program here and install ASSP:

Code:
cd /usr/local/assp
wget [url]
unzip -d /usr/local/assp /usr/local/assp/ASSP_1.2.6-Install.zip
mv --target-directory=/usr/local/assp /usr/local/assp/ASSP/*
mv --target-directory=/usr/local/assp /usr/local/assp/ASSP/.DS_Store
rm -rf /usr/local/assp/__MACOSX
rm -rf /usr/local/assp/ASSP
rm -f ASSP_1.2.6-Install.zip
rm -f Win32-quickstart-guide.txt;rm -f freshclam.bat
cd /usr/local/assp
mkdir pb
cd pb
touch denysmtp.txt
touch exportedextreme.txt
touch pbdb.black.db
touch pbdb.rbl.db
touch pbdb.white.db
cd /usr/local/assp
mkdir /usr/local/assp/notspam
mkdir /usr/local/assp/spam
mkdir /usr/local/assp/errors
mkdir /usr/local/assp/errors/notspam
cd /usr/local/assp
wget [url]
chmod 755 start
wget [url]
chmod 755 stop
cd /etc/rc.d/init.d
wget [url]
chmod 755 assp
The core of ASSP is now installed. However, the development versions have updated functions to use for users. Of course, this is completely optional, but is recommended completely. This can be done by the following in SSH

Code:
cd /usr/local/assp/
mv assp.pl assp.pl_old
mv spamdb spamdb.old
mv rebuildspamdb.pl rebuildspamdb.pl.old
mv repair.pl repair.pl.old
mkdir Data
mkdir Data/Lists
wget [url]
wget [url]
000F4555.2/rebuildspamdb.pl
wget [url]
wget [url]
mv assp.css images
wget [url]
cd Data/Lists
wget [url]
chmod u+x /usr/local/assp/*.pl
Now, let's get it up and running, and configure it, shall we?

Code:
cd /usr/local/assp
/etc/init.d/assp start
You'll see ASSP sending out some messages and then doing nothing. This is ok, and it's the expected response. Now, we need to edit some stuff. Hit ctrl-c (cancel) to shut down ASSP
once it's stopped, you'll see the following file in the assp directory - assp.cfg . Edit that with whatever you want for an editor, something like:

Code:
nano assp.cfg
You want to change a few options immediately just to get it working
Look for the lines that are something like:

Code:
runAsGroup:=
runAsUser:=
and change them to be:

Code:
runAsGroup:=root
runAsUser:=root
Then look for the line that is

Code:
AsADaemon:=
and change it to

Code:
AsADaemon:=1
Now, let's change the password just so that we're secure:
look for the line that is

Code:
webAdminPassword:=nospam4me
and change that to

Code:
webAdminPassword:=insertrandompasswordhere
Now, let's tell ASSP to setup and accept mail for our domains. Look for the line something like

Code:
localDomains:=
and change that to be

Code:
localDomains:=file:/etc/localdomains
Almost there, just a couple more changes needed.
Look for the line that is something like

Code:
smtpDestination:=127.0.0.1:225
and change that to be

Code:
smtpDestination:=127.0.0.1:125
(or another port instead of 125, just REMEMBER the port!)
and one more change
change the line that looks like

Code:
listenPort:=125
to

Code:
listenPort:=25
Now save and exit the file. If you're using nano/pico, that would be ctrl-x , just make SURE to save the file before you exit!
Now, let's get ASSP fired up again

Code:
/etc/init.d/assp start
let's make sure you have assp starting on system boot:

Code:
chkconfig --add assp
Let's add a crontab to make sure that ASSP rebuilds the bayesian spam list

Quote:

crontab -e

Code:
10 4 * * * cd /usr/local/assp;/usr/local/assp/rebuildspamdb.pl
Occasionally, what I've seen is ASSP will get "hung" on certain things and just kill itself. This fix will work for this, and make sure your ASSP installation is running smoothly

Open up another file on the server, my example will be /bin/asspcheck. In this file, add the following contents

Code:
assplog=/usr/local/assp/check.log
DATE=`date "+%m-%d-%y [%k:%M]"`
pidof=/usr/local/assp/pid
thispid=`cat $pidof`
if [ ! -d /proc/$thispid ];then
rm -rf $pidof;
/etc/init.d/assp start
echo "$DATE - ASSP - restarted" >> $assplog
else
echo "$DATE - ASSP - ok" >> $assplog
fi
Now, chmod the file itself

Code:
chmod u+x /bin/asspcheck
Now, make sure it's called every 60 seconds. Add this to your root crontab

Quote:

crontab -e

Code:
* * * * * /bin/asspcheck
Now, let's go BACK into WHM and setup the variables needed to get exim to use ASSP
In exim configuration editor, click on "advanced editor"
Clear out EVERYTHING from all of the existing boxes. Keeping these with data can cause ASSP to not function as it should
When you've done that, add the following to the top box:

Code:
# assp
local_interfaces = 127.0.0.1.125
If you changed this variable to something else

Code:
smtpDestination:=127.0.0.1:125
put in the other port, NOT 125, so it would look like 127.0.0.1.whateverporthere

Click on Save
Exim will restart and you now have a working installation of assp

Now, let's go to it and work with it a bit, shall we?
go to [url], enter the user admin and the password you changed nospam4me to. This will get you logged in and you can tweak the settings as you feel necessary.

ASSP is a great and powerful proxy for any mail server, which blocks using RBLS, whitelists, etc. It is advisable to setup the email interface and let your customers know of this so that you can get them to help you in reporting and addressing spam.

Parts of this howto were taken from this page, however much of that data has been found to be outdated as far as downloads from CVS and the like go, and I've added quite a bit of useful information into it as well.

Go through the ASSP configuration VERY carefully, and ONLY change what you're sure of.

Start with the RBLs, increase the list to 5 and max hits to 2 as suggested.

If you notice problems with this or know how it might be better, hey, feel free to post in here and I'll keep it as updated as possible :)

Exim + Cpanel + Dspam Howto

Mar 21, 2007

I found a handful of howto's for dspam, but none of them catered for exim with virtual users. After hunting around, I eventually have it working on a cPanel server, with user authentication for mail users.

My setup:
dspam version 3.6.8, using mysql driver.
exim version 4.
mysql 4.1
CentOS (2.6.9-023stab033.9-enterprise)
cPanel / WHM - latest RELEASE version.

Download the source, configure and compile:

Code:
# cd /usr/local/src
# wget http://dspam.nuclearelephant.com/sou...m-3.6.8.tar.gz
# tar -zxf dspam-3.6.8.tar.gz
# cd dspam-3.6.8
Configure, replacing user/groups with your web-server user (web / apache / nobody), and use your mysql-include / library paths (will need mysql-devel on rh based systems).

Code:
# ./configure --prefix=/opt/dspam-3.6.8 --with-local-delivery-agent=/usr/sbin/exim --with-storage-driver=mysql_drv --with-userdir=/var/spool/mail/dspam --with-userdir-owner=nobody --with-userdir-group=nobody --with-dspam-mode=none --with-dspam-owner=nobody --with-dspam-group=nobody --enable-whitelist --enable-spam-delivery --enable-alternative-bayesian --disable-dependency-tracking --enable-virtual-users --with-mysql-includes=/usr/include/mysql --with-mysql-libraries=/usr/lib/mysql/ --with-dspam-home=/opt/dspam-3.6.8/var/dspam
# make && make install
Set up mysql

Code:
# mysqladmin -p create dspamdb
# mysql -p
>grant all privileges on dspamdb.* to dspamuser@localhost identified by dspampass;
>flush privileges;
>exit;
Create tables:

Code:
mysql -p dspamdb < /usr/local/src/dspam-3.6.8/src/tools.mysql_drv/mysql_objects_speed.sql
mysql -p dspamdb < /usr/local/src/dspam-3.6.8/src/tools.mysql_drv/virtual_users.sql
Link dspam in opt for easy versioning:

Code:
ln -s dspam-3.6.8 /opt/dspam
Copy the web interface files to a web directory:

Code:
# cp webui/cgi-bin /opt/dspam -r
# cp webui/htdocs /opt/dspam/

This next step is required for pop3 authentication.
Install perl module Apache::AuthPOP3 - which does apache pop3 authorisation:

Code:
perl -MCPAN -e shell
install Apache::AuthPOP3
Next, apache will need mod_perl installed - WHM -> Apache Update will allow you to enable the perl module (I am running it alongside php with no issues).

Then in /usr/local/apache/conf/httpd.conf:

Code:
ScriptAlias /dspam/ /opt/dspam/cgi-bin/
Alias /dspam_files/ /opt/dspam/htdocs/
<Directory /opt/dspam/cgi-bin>
Options None
AllowOverride AuthConfig
Order allow,deny
Allow from all
</Directory>
Create .htaccess in /opt/dspam/cgi-bin as follows:

Code:
AuthName "Dspam"
AuthType Basic
PerlAuthenHandler Apache::AuthPOP3
PerlSetVar MailHost localhost
Require valid-user
#PerlSetVar UserMap pop3user1=>realname1,pop3user2=>realname2
#Require user pop3user1 pop3user2 pop3user3 pop3user4
there are 2 commented parameters you can set when using POP3 auth - sure its pretty self-explanatory.

Set up admin user (the admin_user must be able to authenticate as a pop user):

Code:
#echo "admin_user" >> /opt/dspam/cgi-bin/admins
Create a queuesize script for web user - so dspam can determine how many messages in the queue.

Code:
vi /usr/local/bin/eximqsize
#!/bin/sh

/usr/bin/find /var/spool/exim/input/ -type f | wc -l | cut -d" " -f1-
##EOF

# chmod 4755 /usr/local/bin/eximqsize
# chown nobody /usr/local/bin/eximqsize
Configure web ui, edit /opt/dspam/cgi-bin/configure.pl:

Code:
$CONFIG{'MAIL_QUEUE'} = "/usr/local/bin/eximqsize";
$CONFIG{'WEB_ROOT'} = "/dspam_files";
$CONFIG{'LOCAL_DOMAIN'} = "FQDN"; #your servers fully qualified domain name - e.g. host.yourdomain.com
Next, set the default preferences for the system (you need /opt/dspam/bin in your path if you copy and paste this...):

Code:
dspam_admin ch pref default trainingMode TEFT
dspam_admin ch pref default spamAction quarantine
dspam_admin ch pref default spamSubject "[SPAM]"
dspam_admin ch pref default enableWhitelist on
dspam_admin ch pref default showFactors off
Permissions:
I would suggest reading the README over dspam to get a full understanding of the permissions required for running of dspam. My permissions were:

Code:
# chown nobody:mail /opt/dspam/var/dspam -R
# chown nobody:mail /opt/dspam/etc/ -R

Edit dspam.conf (in /opt/dspam/etc/. I have only listed the parameters I changed here...):

Code:
TrustedDeliveryAgent "/usr/sbin/exim -oMr spam-scanned"

Trust: root
Trust: mail
Trust: nobody / httpd #choose 1 - what ever your webserver runs as - `ps axu | grep httpd` to find out

#Use the same details as you did for the "grant all privileges on...." statement in mysql.
MySQLServer /var/lib/mysql/mysql.sock
MySQLPort
MySQLUser dspamuser
MySQLPass dspampass
MySQLDb dspamdb
MySQLCompress true

MySQLVirtualTable dspam_virtual_uids
MySQLVirtualUIDField uid
MySQLVirtualUsernameField username
Almost there....
Confirm that mysql is configure to listen on a socket in /etc/my.cnf (or whereever your config file is):

Code:
# cat /etc/my.cnf
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
Now the final step - exim configuration. This is the part that took the longest, hopefully it works for you. Just as I read in the howto's I used for this, please please please dont just copy and paste - you stand a good chance of breaking your mail server if you make changes without understanding. Be warned.

My config file is /etc/exim.conf. This should be edited using the WHM -> Exim Configuration Editor -> Advanced.

Code:
#Routers - Add these in the box before virtual_user delivery / user delivery router).
dspam_router:
no_verify
#uncomment the next line to disable dspam for virtual users.
# check_local_user
condition = "${if and {
{!def:h_X-Spam-Flag:}
{!def:h_X-FILTER-DSPAM:}
{!eq {$sender_address_domain}{$domain}}
{!eq {$received_protocol}{local}}
{!eq {$received_protocol}{spam-scanned}}
} }"
headers_add = "X-FILTER-DSPAM: by $primary_hostname on $tod_full"
driver = accept
transport = dspam_spamcheck

## The next 2 routers allow you to forward spam / non-spam to dspam for training (e.g. spam-yourmail@yourdomain.net).
# spam-username
dspam_addspam_router:
driver = accept
local_part_prefix = spam-
transport = dspam_addspam

# nospam-username
dspam_falsepositive_router:
driver = accept
local_part_prefix = notspam-
transport = dspam_falsepositive

##Transports - can be added anywhere:
#this adds the spam-scanned protocol header, so when it is passed back to exim after being processed by dspam, it doesnt get stuck in a loop.
dspam_spamcheck:
driver = pipe
command = "/usr/sbin/exim -oMr spam-scanned -bS"
transport_filter = "/opt/dspam/bin/dspam --stdout --deliver=innocent,spam --user $local_part@$domain"
use_bsmtp = true
home_directory = "/tmp"
current_directory = "/tmp"
user = nobody
group = mail
log_output = true
return_fail_output = true
return_path_add = false
message_prefix =
message_suffix =

dspam_addspam:
driver = pipe
command = "/opt/dspam/bin/dspam --user $local_part@$domain --class=spam --source=error"
home_directory = "/tmp"
current_directory = "/tmp"
user = nobody
group = mail
log_output = true
return_fail_output = true
return_path_add = false
message_prefix =
message_suffix =

dspam_falsepositive:
driver = pipe
command = "/opt/dspam/bin/dspam --user $local_part@$domain --class=innocent --source=error"
home_directory = "/tmp"
current_directory = "/tmp"
user = nobody
group = mail
log_output = true
return_fail_output = true
return_path_add = false
message_prefix =
message_suffix =

If you have set up authentication correctly as well, then you should be able to open [url] and log in - if you add your login details to the "admins" file, you can configure defaults, etc. It also allows ALL users (with 1 user being an email account) to log in, using www.yourclientsdomain.com/dspam/dspam.cgi

This will not work with suexec enabled!! This is because dspam needs specific permissions, and it is expecting user nobody to access it. If suexec is enabled, you will need to use the default host, and NOT virtual hosts (and even this may not work - testing still required).

Watch exim_mainlog after this - you should pick up what transports and routers are being used.

Dspam can really hammer a system - mysql, cpu and memory usage will go up a bit, especially on busy production servers. Monitor your servers performance.

Other settings: add /opt/dspam/man to MANPATH in /etc/man.config or move dspam man directory to an existing man directory.

[ADDED]
This dspam.cgi hack will do a lookup in the cpanel config file to find the domain for any username without a domain, and append it on match (or leave just the username part if nothing is found). This requires unsecuring your system a bit - your http user will need to be able to read /etc/trueuserdomains (either chmod 644 or chown nobody):

Code:
#add this just after $CURRENT_USER is set.
if ($CURRENT_USER !~ /@.+./) {
open(TUD, "</etc/trueuserdomains");
while(<TUD>) {
my ($domain, $user) = split(/:/,$_);
chomp($user);
$user =~ s/^s*//g;
if ($user eq $CURRENT_USER) {
$CURRENT_USER = $CURRENT_USER . "@$domain";
}
}
close(TUD);
}

That should do it

dspam will allow all messages through by default, and will require some training. With this config, users can train using email commands - all they need to do is forward any spam that hits their mailbox to spam-emailaddress@domain.com (their own email address with spam- prepended). Unfortunately this does not allow handling of false positives if you are using a "quarantine" policy instead of subject. the web interface comes in handy for this.

I am busy testing a combination of dspam with assp, which seems to be working well - I especially like the greylisting feature of assp and ProtectionBox... Will add to this howto when testing is finish.

Bandwidth Limiting HOWTO With Linux, Tc And Iproute2

Jul 2, 2008

I've seen a lot of requests for a simple howto dealing with bandwidth limiting/"capping" on Linux. I put together a howto yesterday on this which I hope you'll find useful.

Ifve recently optimized the scripts used for bandwidth management in one of our UK facilities and I thought Ifd post a quick howto on it.

The full script can be found directly here: http://www.adamsinfo.com/bandwith-li...oute2/#more-15

My setup here is a live feed entering eth0 on this linux router and leaving eth1 into a switch connected to a collection of other servers. This is set up as an unrestricted public router, routing between a /30 on eth0 and a /24 on eth1.
Note: We canft in any way restrict the amount of traffic that eth0 receives from the outside, so instead we restrict how fast eth0 sends data out, the same applies the other way round. So, if we want to limit the amount of data that the local servers can send, we shape the routerfs external interface (eth0). If we want to limit the amount of data that the local servers can receive, we shape the routerfs internal interface (eth1)

With Debian Etch on 2.6.x, run:
apt-get install tc iproute2 bc

Then script as follows:
# Set some variables
#!/bin/bash
EXT_IFACE=heth0
INT_IFACE=heth1
TC=htch
UNITS=hkbith
LINE=h10000 #maximum ext link speed
LIMIT=h5000 #maximum that wefll allow


# Set some variables for individual gclassesh that wefll use to shape internal upload speed, i.e. shaping eth0
CLS1_RATE=h200 # High Priority traffic class has 200kbit
CLS2_RATE=h300 # Medium Priority class has 300kbit
CLS3_RATE=h4500 # Bulk class has 4500kbit
# (Wefll set which ones can borrow from which later)

# Set some variables for individual gclassesh that wefll use to shape internal download speed, i.e. shaping eth1
INT_CLS1_RATE=h1000 #Priority
INT_CLS2_RATE=h4000 #Bulk

[...] A few hundred lines [...]

I have tried not to get bogged down with too many irrelevant details here and would be happy to answer any questions or take any corrections. Itfs pretty simple and it works well. Install bmon and you can confirm this yourself. The purpose of this is that I can take a 10mbit connection and limit the traffic to 5mbit ensuring that I donft break the 95th percentile that I want to maintain at the datacenter. I can increase and decrease this at any time as traffic requires or permits respectively.

Howto: FP Uploading Sites With Subwebs (subsites)

Oct 13, 2007

Here is the procedure to upload websites and their subwebs (subsites) with FP 2002/2003
Upload the website with FTP
Install FP extensions
Wait for the DNS to pullulate
Open your remote website with FP
Convert folders to subwebs as needed
Upload (again) all your website files with FP
An error message will appear: "cannot find a web server at <domain name> on port 80 ...."
select <OK>
Wait for FP to stop and a message "status unknown" will appear
start uploading again
A message asking something about replacing remote files will appear. Select <YES>
Repeat the process for each subweb (it might take a while)
At the end, you will find a status message: "Successful upload", or similar
That was all

It works for some hosts with cPanel but I cannot be sure if it works for all

Some just require oppening the remote site with FP and convert the requiered folders to subwebs as neeeded.

Moving MultiAccounts To New Host HowTo Request

May 8, 2007

I know Cpanel has some features to do this unfortunately i have a private lable Pannel
that is why I want to move to a host that can allow me to move all my customers in and out as fast as I need to. There are many reasons to leave or find different hosting
that is not the question the question is how to do this without having your customers
go crazy or if posible to do it without them even noticing more then a short period of downtime late at night.

Please offer any opinions or directions on Pannel choice and methods to make the move seamless.

Mistakes are also very interesting And although we all know every hosting company is willing to help us do this and they are all nice guys it is important that things like this can be done fast and also without need for outside tech support All things are important like checking php versions and perl moduals and apache, mysql, phpMyadmin versions.. is setting up a dns3. and dns4. and asking customers to use that important for fast migration?

Howto Convert Ini_set Function In Code To Php.ini Setting

Jul 6, 2008

I have a website that was running fine for a month or two until my host recently changed some settings on the server, and now it shows a bunch of errors. I contacted the host and they said >

"To avoid the errors, please do not use disabled function. If you need such functionality, you can have your own php.ini on your root http folder containing only necessary option"

Since I'm not a programer, I have no idea what they're talking about. So, I asked them how to do that, they're reply of course was>

"Please consult with the script writer on how to convert ini_set function in your code to php.ini seting. As the script is not encrypted, you can do it with commenting all ini_set calls and write a substitute on php.ini (Create php.ini file in webroot folder)."

I tried to contact the developer, but it appears he has gone MIA! So, now I am left with no clue how to fix the website, so I turn to you guys!

The website is [url]. You can see the errors in the header, but I'll post them here as well>>

"Warning: ini_set() has been disabled for security reasons in /home/buymydom/public_html/includes/global.php on line 3

Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at /home/buymydom/public_html/includes/global.php:3) in /home/buymydom/public_html/includes/global.php on line 32

My question is, How do I convert ini_set function in my code to php.ini?
