Virtualbox installation on Fedora Linux

Hello All,

Virtualbox installation on Fedora Linux This short “how to” will guide a Fedora user with a steps on howto install VirtualBox on a Fedora linux system.

First, become a root and install all required prerequisites:

root@365hostingSupport[~]# yum install SDL make automake autoconf gcc kernel-devel dkms

Download RPM binary package of Virtualbox:

root@365hostingSupport[~]# wget

http://download.virtualbox.org/virtualbox/3.2.12/VirtualBox-3.2-3.2.12_68302_fedora14-1.i686.rpm

Next install a downloaded RPM package with rpm command:

root@365hostingSupport[~]# rpm -i VirtualBox-3.2-3.2.12_68302_fedora14-1.i686.rpm

Recompile vboxdrv modules:

root@365hostingSupport[~]# /etc/init.d/vboxdrv setup

Make your self belong to a group vboxusers:

root@365hostingSupport[~]# usermod -G vboxusers -a username

Now, you need to log out and log in to apply the above group changes. Once you log in into the system again you should have a working version of Virtualbox on your Fedora Linux.

Configure Highly secure cluster with HAProxy

Hello,

 

Configure Highly secure cluster with HAProxy

365HOstingSupport provide the facility to install and configure the HAProxy Clustering and optimization of your server,  HAProxy is very fast and reliable solution offering high availability, load balancing, and proxying for TCP and HTTP-based applications. It is particularly suited for web sites crawling under very high loads while needing persistence or Layer7 processing.

 

 

HAProxy  implements an event-driven, single-process model which enables support for very high number of simultaneous connections at very high speeds. Multi-process or multi-threaded models can rarely cope with thousands of connections because of memory limits, system scheduler limits, and lock contention everywhere. Event-driven models do not have these problems because implementing all the tasks in user-space allows a finer resource and time management. The down side is that those programs generally don’t scale well on multi-processor systems. That’s the reason why they must be optimized to get the most work done from every CPU cycle.

 

HAProxy is known to reliably run on the following OS/Platforms :

Linux 2.4 on x86, x86_64, Alpha, SPARC, MIPS, PARISC
Linux 2.6 on x86, x86_64, ARM (ixp425), PPC64
Solaris 8/9 on UltraSPARC 2 and 3
Solaris 10 on Opteron and UltraSPARC
FreeBSD 4.10 – 8 on x86
OpenBSD 3.1 to -current on i386, amd64, macppc, alpha, sparc64 and VAX (check the ports)

Based on those facts, people looking for a very fast load balancer should consider the following options on x86 or x86_64 hardware, in this order :

HAProxy 1.4 on Linux 2.6.32+
HAProxy 1.4 on Linux 2.4 + epoll patch
HAProxy 1.4 on FreeBSD
HAProxy 1.4 on Solaris 10

DDOS and IPtables

Using following iptables rules we can try to stop ddos.

iptables -I INPUT -p tcp –dport 80 -i eth0 -m state –state NEW -m recent –set
iptables -I INPUT -p tcp –dport 80 -i eth0 -m state –state NEW -m recent –update –seconds 20 –hitcount 50 -j DROP

service iptables save

service iptables restart

 

DOS: How to check it?

Now a days DDOS attack became the usual in the server. You can follow the below checklist to Stop at certain extent.

Steps:

1.How to find DOS attack on the server

[root@root]# pidof httpd

If you find more than 5 rows of PID from above command result, you can suspect there is DOS attack in the server.

2. Run the below script to confirm the DOS attack and block the IPs continuously.

[root@root]# netstat -plan|grep :80|awk {‘print $5’}|cut -d: -f 1|sort|uniq -c|sort -nk 1

OR

[root@root]# netstat -an | grep SYN|sort|uniq|awk ‘{print $5}’|sed ‘s/\:/ /g’|awk ‘{print “csf -d “$1}’

you can find high hit from different IPs. Once You confirm DOS attack in the server ,

4. Now we have to check the “MaxClient” and Timeout value in Apache configuration.

MaxClients 150
Timeout 300

Timeout 300 is the default value. We can reduce bit lower into avoid DOS attack at certain extend

5. Now we have to find , on which are the domain, DOS attack is happening.

[root@root]# cd /usr/local/apache/domlogs/
[root@root]# ls -ltr |tail -50

(it will list the TOP 50 domains which are in high access.

6.Now, Run the following command to know the IPs which is hitting the particular domain..

[root@root]# tail -f domainname | awk {‘print $1’}

7. If the hit is coming from same IP, we can block only those IP. if hit is from different ranges of IP, we have to suspend or disable that account or can block the range of IPs.

8.Instead we can remove the DNS/pdns DB entry for the domain.

[root@root]# mv /var/named/domainname.com.db /var/named/domainname.com.db.bak[root@root]# touch /var/named/domainname.com.db

9. Also remove ZONE entry from PDNS.

10. In WHM : Apache status you can see the domain which is receiving more hits or request. As per that take an action.

11. If attack is not in control then make changes in csf.conf as follows

1. vi /etc/csf/csf.conf

find : CT_LIMIT and set it to 150

2. FIND: SYNFLOOD, SYNFLOOD_RATE and SYNFLOOD_BURST

Set the values as follows:

SYNFLOOD = “1”
SYNFLOOD_RATE = “10/s”
SYNFLOOD_BURST = “15”

Definition: SYN flood: A SYN flood is a type of DoS attack. A SYN packet notifies a server of a new connection. The server then allocates some memory in order to handle the incoming connection, sends back an acknowledgement, then waits for the client to complete the connection and start sending data. By spoofing large numbers of SYN requests, an attacker can fill up memory on the server, which will sit their waiting for more data that never will arrive. Once memory has filled up, the server will be unable to accept connections from legitimate clients.

3. Also enable PORTFLOOD as follows.

PORTFLOOD = “80;tcp;300;5”

3. save and exit

4. Restart csf.

 

How to Count Apache, POP3, IMAP, SMTP and FTP connection

How to Count Apache, POP3, IMAP, SMTP and FTP connection

Using following script or command we can check it.

root@gold [~]# netstat -plan | grep :80 | awk {‘print $5’} | grep -Eo “[[:digit:]]{1,3}\.[[:digit:]]{1,3}\.[[:digit:]]{1,3}\.[[:digit:]]{1,3}” | sort -n -t . -k 1,1 -k 2,2 -k 3,3 -k 4,4|uniq -c | sort -nk 1 > /root/1.out; echo “Apache:”; tail -5 /root/1.out; rm -f /root/1.out; netstat -plan | grep :110 | awk {‘print $5’} | grep -Eo “[[:digit:]]{1,3}\.[[:digit:]]{1,3}\.[[:digit:]]{1,3}\.[[:digit:]]{1,3}” | sort -n -t . -k 1,1 -k 2,2 -k 3,3 -k 4,4|uniq -c | sort -nk 1 > /root/2.out; echo “POP3:”; tail -5 /root/2.out; rm -f /root/2.out;  netstat -plan | grep :143 | awk {‘print $5’} | grep -Eo “[[:digit:]]{1,3}\.[[:digit:]]{1,3}\.[[:digit:]]{1,3}\.[[:digit:]]{1,3}” | sort -n -t . -k 1,1 -k 2,2 -k 3,3 -k 4,4|uniq -c | sort -nk 1 > /root/3.out; echo “IMAP:”; tail -5 /root/3.out; rm -f /root/3.out;  netstat -plan | grep :25 | awk {‘print $5’} | grep -Eo “[[:digit:]]{1,3}\.[[:digit:]]{1,3}\.[[:digit:]]{1,3}\.[[:digit:]]{1,3}” | sort -n -t . -k 1,1 -k 2,2 -k 3,3 -k 4,4|uniq -c | sort -nk 1 > /root/4.out; echo “SMTP(25):”; tail -5 /root/4.out; rm -f /root/4.out;  netstat -plan | grep :26 | awk {‘print $5’} | grep -Eo “[[:digit:]]{1,3}\.[[:digit:]]{1,3}\.[[:digit:]]{1,3}\.[[:digit:]]{1,3}” | sort -n -t . -k 1,1 -k 2,2 -k 3,3 -k 4,4|uniq -c | sort -nk 1 > /root/5.out; echo “SMTP(26):”; tail -5 /root/5.out; rm -f /root/5.out;  netstat -plan | grep :21 | awk {‘print $5’} | grep -Eo “[[:digit:]]{1,3}\.[[:digit:]]{1,3}\.[[:digit:]]{1,3}\.[[:digit:]]{1,3}” | sort -n -t . -k 1,1 -k 2,2 -k 3,3 -k 4,4|uniq -c | sort -nk 1 > /root/6.out; echo “FTP:”; tail -5 /root/6.out; rm -f /root/6.out
———

And the result will be as follows:

Apache:
2 0.0.0.0
2 208.115.111.72
4 91.177.88.53
13 59.94.223.174
