Install Mailscanner MRTG

Luigi Ramone | 15 December, 2005 21:55

This will install Mailscanner MRTG on your system. I have tested it on Ensim 3.1.10 and Ensim 3.5.17. Others have also done this on CPanel, but make sure you make the change noted...

Regular, I am not responsible for your box/you are doing this at YOUR OWN RISK... It should not screw anything up, but you are ultimately responsible if it does. I will help out as much as I can, but I am not a genius.

PREREQUISITES
1) MRTG *MUST* be installed (HOW-TO)
2) Mailscanner *MUST* be installed (I use gpans MS/SA/CM HOW-TO, but there is a MS Only HOW-TO too)

INSTRUCTIONS
cd ~
wget http://umn.dl.sourceforge.net/sourc...rtg-0.05.tar.gz
tar -xzvf mailscanner-mrtg-0.05.tar.gz
cd mailscanner-mrtg-0.05
cp mailscanner-mrtg.conf /etc/MailScanner/
cp mailscanner-mrtg.cfg /etc/mrtg/
cp mailscanner-mrtg /usr/sbin/
cp mailscanner-mrtg.include /etc/httpd/conf/
cp /etc/httpd/conf/httpd.conf /etc/httpd/conf/httpd.conf.bk

Email with attachments from command line

Luigi Ramone | 15 December, 2005 21:53

Sending emails from command line
I’ll describe possible ways to send emails from the command line. Of course there are much nicer ways to do it, but you may be in the situation (such as the one that drove me to do a deeper research and come out with this solution) and will need an easy and fast way to send mails from the prompt.


Simple text emails:
You can send simple emails by using the already installed sendmail program with the following command at the prompt:

echo "Simple, small body Text goes here" | mail -s "The Subject goes here" user@domain.com

If you have already typed a message in a text file, then import the text into the body of the email you are sending by using command:

mail -s "The Subject goes here" user@domain.com < text_file

Disadvantage: the email will be sent using header From: root@host.domain.com

Easy Mailscanner + Clam Antivirus + SpamAssassin *Updated 5/9/2003*

Luigi Ramone | 15 December, 2005 21:52

We have put together the following package which will install Mailscanner, Clam Antivirus and SpamAssassin on your Ensim 3.1, or Ensim Pro 3.5 server.

This package installs:
Mailscanner 4.22
Clam Antivirus 0.60
SpamAssassin 2.55


We have tested it on upgrades from 4.11 + Mailscanner versions without issues. If you have an older Mailscanner install, we would recommend uninstalling it first and deleting the /etc/MailScanner folder before running this package.

This package does not use f-prot as you need a commercial license for use in a business environment.

Set up Tripwire on RedHat

Luigi Ramone | 15 December, 2005 21:45

Install tripwire

It's installed by default, but if it isn't, grab your RedHat disks, and install it:

---------------------

# rpm -ihv /mnt/cdrom/RedHat/RPMS/tripwire-2.3.1-5.i386.rpm
# /etc/tripwire/twinstall.sh

---------------------

Clean the policy file
Go over to /etc/tripwire, and clean out the policy file with this handy script:

---------------------

# cat > ./cleantw.pl
#!/usr/bin/perl

while (<>){
#look at the line, and check for a line that can be
# Construed as a file name
CASE:{
( m|(^s*)(/[/w._-]+)(s+->.*)| ) and do {
print $1;
print "#" unless (-e $2);
print "$2$3n";
last;
};

print $_;
}
};
^D
#

---------------------

Use SFTP (Secure FTP via SSH2) instead of FTP

Luigi Ramone | 15 December, 2005 21:41

NOTE: If you have SSH set up on your server, your server is ready to be an SFTP server. SFTP uses SSH.


What does this How-To show you?

a. How to install, setup and use an SFTP client to connect to your box using SSH2 to download/ upload files rather than FTP.

b. How to block port 21 (the default FTP port) which you don't need anymore.

c. How to uninstall and remove the FTP server from your box (if you don't need it anymore).


Why you should NOT use normal FTP

Most people use normal unsecure FTP do upload and download files to their servers using an FTP client from home.

The problem with this is that YOUR USERNAME AND PASSWORD are sent in PLAIN TEXT - a hacker can easily get this information and use it to gain access to your server.

APF Firewall 0.9.4-7

Luigi Ramone | 15 December, 2005 21:32

Just thought I'd update the howto's for APF.

Type ifconfig

Find out if it’s using eth0 or eth1.

Usually its eth0 but if its not, change it in conf.apf or you’ll be completely blocking the server from access

wget http://www.rfxnetworks.com/downloads/apf-current.tar.gz

tar -xvzf apf-current.tar.gz
cd apf*
./install.sh
pico -w /etc/apf/conf.apf

RESV_DNS="1"

All SYSCTL options should be set to 1 EXCEPT for
SYSCTL_OVERFLOW="0"
SYSCTL_SYNCOOKIES="0"

USE_DS="1"
USE_AD="1"

Antidos via APF Firewall

Luigi Ramone | 15 December, 2005 21:30

Antidos is a really nice feature of the APF firewall, but it's not automatically turned on when you install and run APF.

First you probably want to make sure APF is running nicely for a few days and you have your own IP listed in the "allow_hosts.rules" file so you can't lock yourself out. You also want to understand how to access the EV1 remote console (from your EV1 account manager), just in case you do lock yourself out.

And to be even more safe, lets set DEVEL_MODE to "1" (on) and we need to setup USE_AD to enable the use of antidos, so find and edit these:

pico -w /etc/apf/conf.apf

DEVEL_MODE="1"

USE_AD="1"

apf -r

Now APF will quit in 5 minutes. Don't forget to put DEVEL_MODE back when everything is OK!

Using fail2ban to ban abusive IP's for SSH and Apache

Luigi Ramone | 15 December, 2005 21:24

How to automatically ban abusive ip's using fail2ban

Originally from Ensim 4.0; similar steps had to be taken after the upgrade to 4.0.2; I would assume the same follows until python 2.3 is included [it may already be; corrections welcome].

Fail2Ban scans log files like /var/log/pwdfail or /var/log/apache/error_log and bans IP that makes too many password failures. It updates firewall rules to reject the IP address.

Install/Upgrade ProFTPd

Luigi Ramone | 15 December, 2005 21:22

Ensim
I'm not going to handle Ensim again since gpan made a nice Howto on this issue and even created
rpms for your usage all information can be found here.
After installing it you can also do the proftpd.conf tweak but you have todo pico -w /etc/proftpd.conf
note:
1. that i can't give any support on the rpm made by gpan, so that will have to go through him.
2. Mouse is against upgrading your ProFTPd on Ensim when you run a up to date 3.1.x and 3.5.x

Plesk
Nighthawk just said to me that this is actually a bad idea for Plesk.
Nighthawk has years of experience with Plesk so i fully support what he's saying about Plesk whatsoever .
So your officially warned by me and NightHawk so dont do this howto on your system.
You will destroy it otherwise but you can do the proftpd.conf tweak without a problem, so just skip most of this how-to and usage pico -w /etc/proftpd.conf instead just like Ensim.

This guide will continue to be updated and should not be considered a complete list of SSH commands or linux shell commands, but commands, we found, often used.

Upgrade kernel on Dual Xeons

Luigi Ramone | 15 December, 2005 21:15

Updated for latest kernel (RH 7.3):

2.4.20-24.7

This is the way I did it - I went to 2.4.20-18.7 first, then went to 2.4.20-20.7. (in any case I am running 2.4.20-20.9 which is the latest for RH 9 - this How-To assumes you are running RH 7.3, but the steps are the same).

This section has 2 parts:

If you are running a kernel that is OLDER THAN 2.4.20-18.7 run PART A first, then PART B.

If you are already running 2.4.20-18.7, go straight to Part B.
