Server hacking Precuations

Web hacks happen due to a lot of reasons, especially for common CMS scripts like WordPress. It can be a bad theme, plugin or an insecure permission. As you can see, we gave the customer steps to secure his wordpress website and he said he will implement it.
We can avoid 99% of hacks by securing the WP Admin area, wp-contents and avoiding low rated plugins/themes. I will have the quality department add/implement few more steps to check these hacks.
Server hacking/ check
=====================
- Logs, check entries from IP’s and what they accessed.
- File/Folder permissions secure?
- All passwords for root, mysql, ftp, etc should be changed to something more difficult
- Brute force should be installed
- Check for the scripts they may have gained access from
>> We can also run maldet, clamav anti viruses on that server to prevent further hacking

File found while using the cmd locate but it was hidden >> Hacked

This issue might be a funny one but too dangerous
====
We can locate the file

locate example..

But we cannot see the file or folder by using  ll, ls , vi ,cd cmds..
The amazing fact is there is no log too. But using the hacked file we can easily login with out permission and upload and sown load the files ..
I have sorted this issue by finding the script in the .htacess file and in the index.php, and php.ini file
tough but crazy one

Server load high but no cpu usage

Just check the load via user ..
like
/usr/local/cpanel/bin/dcpumonview | sed -e ‘s/<[^>]*>/ /g’ | grep  username
ex:  /usr/local/cpanel/bin/dcpumonview | sed -e ‘s/<[^>]*>/ /g’ | grep  root

What is RAID?

RAID (redundant array of independent disks; originally redundant array of inexpensive disks) is a way of storing the same data in different places (thus, redundantly) on multiple hard disks. By placing data on multiple disks, I/O (input/output) operations can overlap in a balanced way, improving performance. Since multiple disks increases the mean time between failures (MTBF), storing data redundantly also increases fault tolerance.
How to reload server with Raid-1 using mdadm raid
We need two identical hard disks for doing this. Let this be sda and sdb.
When reaching the partition menu we need to select custom layout
Follow the steps below for the first drive:
Click Create
From the popup choose RAID Partition and click Create
From the popup select ONLY sda, set the Size to 1000MB (this is the size for /boot), select Fixed size, select Force to be a primary partition and click OK.
For the second drive the steps are similar but in the second pop-up select sdb:
Click Create
From the popup choose RAID Partition and click Create
From the popup select ONLY sdb, set the Size to 1000MB (this is the size for /boot), select Fixed size, select Force to be a primary partition and click OK.
In the main overview we need to create a RAID device for /boot:
Click Create
From the popup choose RAID Device and click Create
From the popup set the Mount Point to /boot, select both sda1 and sdb1 and click OK.
Now we can continue creating the other partitions.
Start with the first drive:
Click Create
From the popup choose RAID Partition and click Create
From the popup select ONLY sda, select Fill to maximum allowable size and click OK.
Second drive:
Click Create
From the popup choose RAID Partition and click Create
From the popup select ONLY sdb, select Fill to maximum allowable size and click OK.
In the main overview we need to create a RAID device for the other partitions:
Click Create
From the popup choose RAID Device and click Create
From the popup I have set the mount point as / and continued with the installation.
Please let me know if you have any further queries.

SoftRAID +New server : Reloading server

In this thread we will see how to provision a server with Software RAID once the server is booted in OS.
1. Install OS with ISO over IPMI on sda drive.
2. yum install mdadm initramfs-tools
3. # Add raid1 or raid0 to /etc/modules
echo “raid1″ >> /etc/modules
(for raid0 add that module)
echo “raid0″ >> /etc/modules
4. # Regenerate initrd.img file
mkinitramfs -o /boot/test -r /dev/mapper/root (replace /dev/mapper/root with your actual LVM root partition)
5. # Rename old img file (replace .x for whatever kernel version you are using)
mv /boot/initrd.img-x.x.x /boot/initrd.img-x.x.x.original
6. # Rename new img file
mv /boot/test /boot/initrd.img-x.x.x
7. grub-install –no-floppy /dev/sda
grub-install –no-floppy /dev/sdb
8. # Change UUID for (hd0,0) on /boot/grub/menu.1st if your file has the UUID in it.
# This most likely involves replacing the root UUID=XXXXX line with root hd(0,0)
# vi /boot/grub/menu.1st
9. Change UUIDs for proper md0 devices on /etc/fstab if your file has the UUID in it.
# Now do the same thing for the /etc/fstab file.
# Replace the UUID=XXXXXXXXX /boot ext3 defaults 0 1 line with /dev/md0 /boot ext3 defaults 0
# vi /etc/fstab
10. Clone the partition table from 1st drive to 2nd
sfdisk -d /dev/sda | sfdisk –force /dev/sdb
11. Create md devices with second drive only
mdadm –create /dev/md0 –level=1 –raid-devices=2 missing /dev/sdb1
mdadm –create /dev/md1 –level=1 –raid-devices=2 missing /dev/sdb2
12. Save new mdconf file
mdadm –detail –scan >> /etc/mdadm/mdadm.conf
13. # Get boot device setup
mkfs.ext3 /dev/md0
mkdir /mnt/md0
mount /dev/md0 /mnt/md0
cp -ax /boot/* /mnt/md0
umount /mnt/md0
umount /boot; mount /dev/md0 /boot
sfdisk –change-id /dev/sda 1 fd
mdadm –add /dev/md0 /dev/sda1
14. # Setup data device
pvcreate /dev/md1
vgextend pve /dev/md1
# this step takes a LONG time
pvmove /dev/sda2 /dev/md1
vgreduce pve /dev/sda2
sfdisk –change-id /dev/sda 2 fd
mdadm –add /dev/md1 /dev/sda2
15. Rebuilding an array currently requires us to manually rebuild the partition table on the fresh hard drive. We need to know which drive is still active and which one is the new one. To see this let’s run the following command:
# cat /proc/mdstat
Personalities : [raid1]
md0 : active raid1 sdb1[0]
104320 blocks [2/1] [U_]
md1 : active raid1 sdb2[0]
1052160 blocks [2/1] [U_]
md2 : active raid1 sdb3[0]
243039232 blocks [2/1] [U_]
unused devices: <none>
To read this look at the first managed disk, md0. If you are adding back in a partition on a drive that is not empty you may have to keep track of which drive different ones are on. For the current purposes we will assume that we are installing a fresh, unpartitioned drive.
16. We need to see what the current drive is partitioned as, so we can duplicate the same partition table on the new drive:
# fdisk -l /dev/sdb
Disk /dev/sdb: 250.0 GB, 250059350016 bytes
255 heads, 63 sectors/track, 30401 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot      Start         End      Blocks   Id  System
/dev/sdb1   *           1          13      104391   fd  Linux raid autodetect
/dev/sdb2              14         144     1052257+  fd  Linux raid autodetect
/dev/sdb3             145       30401   243039352+  fd  Linux raid autodetect
… and just to verify that /dev/sda is blank …
# fdisk -l /dev/sda
Disk /dev/sda: 250.0 GB, 250059350016 bytes
255 heads, 63 sectors/track, 30401 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot      Start         End      Blocks   Id  System
17. Now we need to edit the partition table on /dev/sda to match exactly what we see on /dev/sdb.
# fdisk /dev/sda
The number of cylinders for this disk is set to 30401.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)
Command (m for help): n
Command action
e   extended
p   primary partition (1-4)
p
Partition number (1-4): 1
For the cylinder start/stop values just refer to the existing partition table. It says “Start” and “End” values for each partition. If you just copy these exactly as the fdisk -l for that drive outputs it will create them exactly the same for you.
First cylinder (1-30401, default 1): 1
Last cylinder or +size or +sizeM or +sizeK (1-30401, default 30401): 13
Command (m for help): p
Disk /dev/sda: 250.0 GB, 250059350016 bytes

Device Boot      Start         End      Blocks   Id  System

Command (m for help): p

Device Boot      Start         End      Blocks   Id  System
/dev/sda1               1          13      104391   83  Linux
/dev/sda2              14         144     1052257+  83  Linux

Last cylinder or +size or +sizeM or +sizeK (145-30401, default 30401): 30401
18. We need to set the boot partition as bootable or this drive won’t be very useful if the other dies
Command (m for help): a
Partition number (1-4): 1
19. Now we need to set the partition type to ‘fd’ for all of the partitions which is hex for a linux raid partition.
Command (m for help): t
Partition number (1-4): 1
Hex code (type L to list codes): fd
Changed system type of partition 1 to fd (Linux raid autodetect)
Command (m for help): t
Partition number (1-4): 2
Hex code (type L to list codes): fd
Changed system type of partition 2 to fd (Linux raid autodetect)
Command (m for help): t
Partition number (1-4): 3
Hex code (type L to list codes): fd
Changed system type of partition 3 to fd (Linux raid autodetect)
20. Let’s look at the partition table we created, it should be identical to the one above from the existing hard drive.
Command (m for help): p
Disk /dev/sda: 250.0 GB, 250059350016 bytes
255 heads, 63 sectors/track, 30401 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1          13      104391   fd  Linux raid autodetect
/dev/sda2              14         144     1052257+  fd  Linux raid autodetect
/dev/sda3             145       30401   243039352+  fd  Linux raid autodetect
21. If it looks good then we use w to write to the disk and exit
Command (m for help): w
The partition table has been altered!
Calling ioctl() to re-read partition table.
Syncing disks.
22. I usually run ‘cat /proc/mdstat’ again so I can see the partitions and compare as I add the newly created partitions back into the raid array.
# cat /proc/mdstat
Personalities : [raid1]
md0 : active raid1 sdb1[0]
104320 blocks [2/1] [U_]
md1 : active raid1 sdb2[0]
1052160 blocks [2/1] [U_]
md2 : active raid1 sdb3[0]
243039232 blocks [2/1] [U_]
unused devices: <none>
23. Now we have to add in each of the partitions back into the managed disks, one at a time. I run ‘cat /proc/mdstat’ again after each addition to make sure it worked.
# mdadm /dev/md0 –add /dev/sda1
mdadm: added /dev/sda1
# cat /proc/mdstat
Personalities : [raid1]
md0 : active raid1 sda1[1] sdb1[0]
104320 blocks [2/2] [UU]
md1 : active raid1 sdb2[0]
1052160 blocks [2/1] [U_]
md2 : active raid1 sdb3[0]
243039232 blocks [2/1] [U_]
unused devices: <none>
# mdadm /dev/md1 –add /dev/sda2
mdadm: added /dev/sda2
# cat /proc/mdstat

md0 : active raid1 sda1[1] sdb1[0]
104320 blocks [2/2] [UU]
md1 : active raid1 sda2[2] sdb2[0]
1052160 blocks [2/1] [U_]

# mdadm /dev/md2 –add /dev/sda3
mdadm: added /dev/sda3

[>....................]  recovery =  0.1% (308480/243039232) finish=78.6min speed=51413K/sec
unused devices: <none>
24. The last step is to update/refresh the grub configuration on both drives. These steps need to be taken on the main drive (eg. /dev/sda not /dev/sda1) of each member of the RAID array:
# /sbin/grub
grub> device (hd0) /dev/sda
grub> root (hd0,0)
grub> setup (hd0)
grub> device (hd0) /dev/sdb
grub> root (hd0,0)
grub> setup (hd0)
grub> device (hd0) /dev/sdX
grub> root (hd0,0)
grub> setup (hd0)
NOTE: the device name changes, but the grub values (hd0) do not. This ensures that the drives are detected properly in a failure situation.
And that is it. We are rebuilding as you can see. In this case it should take almost an hour and a half to rebuild the largest partition, with the smaller ones done almost as fast as you can type the commands.

memory exceeds >> php.ini file edit

The error normally occurs when PHP tries to process a big database records or when importing or exporting. To solve the error, there are two fixes. One is to increase PHP memory limit of the account by using a custom php.ini file. But sometimes it won’t work.
If it didn’t work, then you can fix the error by increasing the memory of the particular PHP script (displayed in error message) by adding an additional line at the top of the script:

Code: [Select]

ini_set(”memory_limit”,”32M”);  

(Change the value based on the error message).
Now browse the page again, perform the operation again. It will just work fine if you have set correct value based on the error message.

Can not open `/var/lib/mlocate/mlocate.db’: No such file or directory

The locate command is a very useful command to find the exact path/location of files in Linux if you know the file name. You can install it using yum and the package is mlocate.

Quote

can not open `/var/lib/mlocate/mlocate.db’: No such file or directory

It is a common issue while using locate command, and the error is because we haven’t created the db for locate. To create db for locate, simply run the command :

Code: [Select]

# updatedb

Wait for it to complete and run the locate command again. It should be working fine this time…!!! 
You can use the same command (updatedb)to update recent changes to locate’s db.

Enable MySQL slow query log

The slow query log consists of SQL statements that took more than long_query_time seconds to execute and required at least min_examined_row_limit rows to be examined. It is very helpful in troubleshooting bad queries.
Add the following to /etc/my.cnf file to enable the slow query log:
Code: [Select]
log-slow-queries=/var/lib/mysql/slow.log
After that, then do the following commands to create the file with the right ownership and file permissions:
Code: [Select]
touch /var/lib/mysql/slow.log
Code: [Select]
chmod 660 /var/lib/mysql/slow.log
Code: [Select]
chown mysql:mysql /var/lib/mysql/slow.log

Php page showing a warning message: phpinfo() has been disabled

If you get the message while browsing php info page, it means that phpinfo function is disabled. To resolve this you will have to :
Remove phpinfo from disable_functions in php.ini
To locate php.ini file, use command :

Code: [Select]

# php --ini

Check the line Loaded Configuration File: for php.ini location. Remove phpinfo  from disable_functions in php.ini and save it.
Now check the phpinfo page

Softaculous – The INFO.XML file could not be found!

This happens if the scripts are not downloaded. The fix is to run CRON :
SSH to your server as root and enter following commands:
For cPanel:
# /usr/local/cpanel/3rdparty/bin/php /usr/local/cpanel/whostmgr/docroot/cgi/softaculous/cron.php
For Direct Admin:
#  /usr/local/bin/php -d open_basedir=/ -d safe_mode=0 -d disable_functions=”" /usr/local/directadmin/plugins/softaculous/cron.php
For Plesk:
SSH to your server as root and enter following command :
# php /usr/local/softaculous/cron.php

Whitelist an IP from IPTABLES

To check if an IP is blocked in iptables, use the command :
Code: [Select]
# iptables -nL | grep IP
Sample output :
DROP       all  –    x.x.x.x    0.0.0.0/0
If the IP is blocked in iptables, to see the rule :
Code: [Select]
iptables-save|grep IP
Sample output :
-A LOCALINPUT -s x.x.x.x -i eth0 -j DROP
Take the results and replace “-A” with “-D” and run it with iptables
Eg : iptables -D LOCALINPUT -s x.x.x.x -i eth0 -j DROP

Solusvm master and slave installation for KVM/XEN/OPenvZ

Solus Vm master means>> Normal solusVm that we are used as the up to node level handling
==============================
Note:

>> CANNOT Install a SolusVM Master on a Xen/KVM Slave Directly >> install your SolusVm Master on a Xen VPS which is hosted on this slave.

This Script should NEVER be used to upgrade SolusVM to the latest version, doing so will destroy your installation of SolusVM

DO NOT use this installer on servers that contain any other control panel (cPanel, Directadmin etc..) Always use a clean install of CentOS/RHEL/Scientific!
===============================

Supported Host Operating Systems

    CentOS 5/6
    RHEL 5/6
    Scientific Linux 5/6

Reload the vps and make the partition as below
KVM                           Xen                 OpenVZ

5> select your Option
====
Once the installer is complete you will be presented with the slave keys and any further instructions for your install type.

Note:
If you need to install a master that 'won't' host any virtual servers, select option 1 (recommended)

If you need to install a master that 'will' host virtual servers, select option 2
====


Once installed go to http://myipaddress:5353/admincp/ and login using (uname) vpsadmin (pword) vpsadmin
==============
==================
=======================
Installing a Slave
====
 Same steps as In master Installation
Install SolusVM Slave
    wget http://soluslabs.com/installers/solusvm/install
   chmod 755 install
   ./install

   Once the installation Complete >> Copy the key and pass
 ======================

 Add this slave to your SolusVM master using the following details:

 ID Key .......... : 6IK10OCRJEZWXYWME909GQW5RR6
 ID Password ..... : EEFbx0bH6QfJhLUs5VyBAWXwXXeIAGuT1kV0k2koEWbEbhsQrNb

 Edit /boot/grub/menu.lst and set the Xen kernel to boot (usually default=0)

 IMPORTANT!! Run: php -f /usr/local/solusvm/includes/xenkernel.php after you have rebooted into the Xen kernel!

 Please set SELINUX=disabled in /etc/selinux/config before rebooting.


=======
EX:

1. Partition layout:
    /dev/sda1    --    /boot            (1024MB)
    /dev/sda2    --    LVM PV
                -VolGroup00
                --LogVol01    /    (24544MB)
                        swap    (8192MB)
    /dev/sda3    --    LVM PV
                -VolGroup01    unmounted, rest of space
=======
2)

 Install Xen do the following first
    yum -y install xen-kernel xen xen-devel
 Install KVM dowsn't need to alter the kernel 
 Install OpenVZ No need of slave(or you could create a slave openvz )
   Then Do the following
    cd /etc/yum.repos.d
    wget http://download.openvz.org/openvz.repo
rpm --import  http://download.openvz.org/RPM-GPG-Key-OpenVZ
yum -y install ovzkernel-xen
yum -y install vzctl vzctl-lib vzquota
=========

//
vi /boot/grub/menu.lst
    Set default boot option to 0
    Insert “dom0_mem=512M” without quotes after the kernel.

 Example:
  
default=0
timeout=3
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
title CentOS (2.6.18-194.17.1.el5.028stab070.7xen)

LSI MegaRAID Email Alerts

To start, the server needs to have either postfix or sendmail installed


Check
====

ls /etc/init.d | grep postfix   (defaults)

ls /etc/init.d | grep sendmail
===========
if not installed

yum install postfix -y 
yum install sendmail -y
======
chkconfig postfix on 
chkconfig sendmail on

======================

Set cronjob for mail aleart

=========== 

cd /etc/cron.hourly
vi MegaRAIDcron

#!/bin/bash
cd /opt/MegaRAID/MegaCli
./MegaCli64 -AdpAllInfo -aALL | grep "Degraded" > degraded.txt
./MegaCli64 -AdpAllInfo -aALL | grep "Failed" >> degraded.txt
cat degraded.txt | grep "1" > /dev/null
if [[ $? -eq 0 ]];
then
cat degraded.txt | mailx -s 'Degraded RAID on '$HOSTNAME <testgmla@gmail.com> 

fi       

==============
To test cron, we need to make one small change to the file. Change the following:

From
cat degraded.txt | grep "1" > /dev/null

To
cat degraded.txt | grep "0" > /dev/null

Save the changes and run the cron manually:

/etc/cron.hourly/MegaRAIDcron

If you have installed everything correctly, you should receive an email which shows the following:

Degraded : 0
Security Key Failed : No
Failed Disks : 0
Deny Force Failed : No
