Multiple VNC Users on a debian / ubuntu

Problem: My kids want to VNC into a VM and use it.

Solution: 

apt update && apt install tigervnc-standalone-server xfce4 xfce4-goodies

adduser kid1

su - kid1

You should now be in the kid1 user.

==== KID1 ====

vncpasswd

nano ~/.vnc/xstartup

==== CODE ====

#!/bin/sh

unset SESSION_MANAGER

unset DBUS_SESSION_BUS_ADDRESS

exec startxfce4

==== CODE ====

chmod +x ~/.vnc/xstartup

exit

==== KID1 ====

On the server, 

nano /etc/tigervnc/vncserver.users 

==== CODE ====

:3=kid1 #This means port 5900 + 3 = kid1 screen

==== CODE ====

systemctl daemon-reload

systemctl enable tigervncserver@:3.service

systemctl start tigervncserver@:3.service

Might need UFW allow

ufw allow 5901:5905/tcp

Default is listen to 127.0.0.1

To listen to 0.0.0.0

vim /etc/tigervnc/vncserver-config-defaults 

enable > $localhost="no"

Blank screen after some time while using ESXi + Ubuntu / Debian

Problem: After some time, the screen went black. From VCSA, unable to click console.

Solution1: If you still can ssh, ssh in and issue `sudo systemctl restart gdm` for a temp fix.

Solution2: `sudo apt install -y dconf-editor gnome-shell-extension-manager`

Run dconf-editor in a GUI, search for power especially org > gnome > settings-daemon > plugins > power > ambient-enabled.

Turn off all sleep features.

Solution 3:

Changing the settings in /etc/gdm3/custom.conf to WaylandEnable=false worked well.

Updating old esx servers to ESXi 6.7

A few of the old ESXi servers are lying around and needs to be upgraded.

Power all VM.
Turn on maintenance mode.
Enable SSH
SSH into the server

esxcli network firewall ruleset set -e false -r httpClient
esxcli software sources profile list --depot=https://hostupdate.vmware.com/software/VUM/PRODUCTION/main/vmw-depot-index.xml | grep 6.7
esxcli software profile update -d https://hostupdate.vmware.com/software/VUM/PRODUCTION/main/vmw-depot-index.xml -p ESXi-6.7.0-8169922-standard
Might wanna open another SSH
tail -f /var/log/esxupdate.log
esxcli network firewall ruleset set -e false -r httpClient
reboot

Kali Linux - Creating your own distro

A colic of mine was trying to act cute and said he wanted his own custom version of kali linux.
As remaster-sys might not work, ( i think ), went on to figure if it's really possible.
As he sucks in googling, here are the steps for my own reference.

Install Kali to a VM.
apt update && apt install curl git live-build
git clone git://git.kali.org/live-build-config.git
cd live-build-config
Inside the kali-config folder, there are various "environments" available.
I choose the LIGHT version as though it's a variant of the XFCE env, it's really light.
With this in mind, lets add some "special" packages that my colic wants.
Edit the config in kali-config/variant-light/package-lists/kali.list.chroot
Add your packages etc.
As he wanted to add custom "code and scripts" as well, add them to kali-config/common/includes.chroot/ folder. EG: root/Desktop/aaa.txt will make the aaa.txt appear on the root desktop.
To enable SSH on startup, 
echo ‘update-rc.d -f ssh enable’ >> kali-config/common/hooks/01-start-ssh.chroot
chmod 755 kali-config/common/hooks/01-start-ssh.chroot
Once done, build the image.
./build.sh --variant light --verbose
Drink coffee and the build ISO will be at: images/xxx.iso

VM Fusion Persistant Disk

Add a new hard disk to your VM Fusion.
Open up the VMX File in your editor.
Search for your workdisk
scsi0:1.fileName = "YOUROWKDISK-000001.vmdk"

Add in the following lines
scsi0:1.mode = "independent-persistent"
snapshot.disabled = "TRUE"
snapshot.action = "keep"

To take snapshot. Shut down the VM. 
Then take the snapshot

Blank screen after some dist-upgrade

So my kali was doing some dist-upgrade.
Took wayyyyy too long and i just killed it.
However, next reboot, everything was black. =_+''

After booting, press Ctrl+Alt+F1~F12.
This should get you a terminal.
Login as root
dpkg --configure -a
WAIT PATIENTLY ( which i failed )
Once done, reboot, volia.

Auto Backup MYSQL DB table structure

Usually during coding, one would often forgot about the MySQL databases structure.
I would usually check in my code but not my DB design.

Below is a sh file that backup the MySQL table structure.
Not the best script. But it does the job.

#!/bin/bash

Host=localhost
BDir=/root/SQLStructureBackup/

Dump="/usr/bin/mysqldump -d -h $Host -u BACKUPUSER -pSOMEPASSWORDHERE "
MySQL=/usr/bin/mysql

Today=$(date +%Y-%b-%d)

# Get a list of all databases
Databases=$(echo "SHOW DATABASES" | $MySQL -u BACKUPUSER -pSOMEPASSWORDHERE)

for db in $Databases; do
        date=`date`
        file="$BDir/$Today-$db.sql.gz"
        echo "Backing up '$db' from '$Host' on '$date' to: "
        echo "   $file"
        $Dump $db | gzip > $file
done

Getting SAMBA to work

One of my colics have trouble setting up samba for his linux server.
apt-get install samba smbfs
Edit the samba config file at /etc/samba/smb.conf
# Global parameters
[global]
       workgroup = HOME
       netbios name = SAMBA
       server string = Samba Server %v
       map to guest = Bad User
       log file = /var/log/samba/log.%m
       max log size = 50
       socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
       preferred master = No
       local master = No
       dns proxy = No
       security = User
        hosts allow = 127. XXX.XXX
        interfaces = 127.0.0.1/8 XXX.XXX.XXX.XXX/16
        bind interfaces only = yes
        guest account = nobody
        null passwords = no
        username level = 6
        #password level = 6
        encrypt passwords = true
        unix password sync = yes
        domain master = no
        preserve case = yes
        short preserve case = yes
# Share
[files]
       path = /files/
       valid users = SOMEUSERHERE
       read only = No
       create mask = 0777
       directory mask = 0777

useradd -c "NAME HERE" SOMEUSERHERE
smbpasswd -a SOMEUSERHERE

*Note that usually samba will not start if your config is wrong..

Single boot kali into MAC

Friend has an old imac around.

Decided to install it with kali.

Pop in kali usb and press OPTION to boot menu.

Should see a WINDOWS and EFI BOOT partition.

Choose windows and install normally.

After installation, boot back to LIVE MODE.

Syncing Apple Wireless Mouse and keyboard to kali

And so i have an old apple mouse and keyboard and decided to sync it to kali via bluetooth instead!

Holding on the keyboard power button throughout the syncing not sure if it works.

Bluetooth setup was a hassle.

So...

apt-get install blueman

Then run blueman-manager
:P

Setting up mod-security for apache.

And so we were looking into WAF for our sites....
Lets go...

apt-get install libapache2-modsecurity

Verify that all is well. If there is a shared, all is well.
apachectl -M | grep --color security

Rename the config file..
mv /etc/modsecurity/modsecurity.conf{-recommended,}

Restart apache
/etc/init.d/apache2 restart

Logs should be in /var/log/apache2/modsec_audit.log

Let's enable modsecurity
nano /etc/modsecurity/modsecurity.conf
SecRuleEngine DetectionOnly becomes SecRuleEngine On
SecResponseBodyAccess On becomes SecResponseBodyAccess Off
Restart apache

Test SQL injection
Create a php

<html> <body> <?php if(isset($_POST['login'])) { $username = $_POST['username']; $password = $_POST['password']; $con = mysqli_connect('localhost','root','password','sample'); $result = mysqli_query($con, "SELECT * FROM `users` WHERE username='$username' AND password='$password'"); if(mysqli_num_rows($result) == 0) echo 'Invalid username or password'; else echo '<h1> Logged in</h1> <p> A Secret for you....</p> '; } else { ?> <form action="" method="post"> Username: <input type="text" name="username"/><br /> Password: <input type="password" name="password"/><br /> <input type="submit" name="login" value="Login"/> </form> <?php } ?> </body> </html>
Change password to suit your database.

Login to MYSQL.
mysql -u root -p
create database sample;
connect sample;
create table users(username VARCHAR(100),password VARCHAR(100));
insert into users values('jesin','pwd');
insert into users values('alice','secret');
quit;

Test your page to see if can login.
Then under username, use this: ' or true -- 
Note the space behind --
You should be able to login. FUCK!!!!

Lets get the ruleset.
wget "https://github.com/SpiderLabs/owasp-modsecurity-crs/tarball/v2.2.5"
tar -zxf 

Lets move the ruleset
rm -rf /usr/share/modsecurity-crs/*
mkdir /usr/share/modsecurity-crs
mv SpiderLabs-owasp-modsecurity-crs-5c28b52/* /usr/share/modsecurity-crs/
cd /usr/share/modsecurity-crs/
mv modsecurity_crs_10_setup.conf.example modsecurity_crs_10_setup.conf
cd /usr/share/modsecurity-crs/activated_rules/
ln -s ../modsecurity_crs_10_setup.conf .
for f in `ls /usr/share/modsecurity-crs/base_rules/` ; do sudo ln -s /usr/share/modsecurity-crs/base_rules/$f /usr/share/modsecurity-crs/activated_rules/$f ; done
for f in `ls /usr/share/modsecurity-crs/optional_rules/` ; do sudo ln -s /usr/share/modsecurity-crs/optional_rules/$f /usr/share/modsecurity-crs/activated_rules/$f ; done

nano /etc/apache2/mods-available/mod-security.conf
Add in the following 2 lines
        Include "/usr/share/modsecurity-crs/*.conf"

        Include "/usr/share/modsecurity-crs/activated_rules/*.conf"

Make sure that mod-security.conf is something like that...


        # Default Debian dir for modsecurity's persistent data
        SecDataDir /var/cache/modsecurity

        # Include all the *.conf files in /etc/modsecurity.
        # Keeping your local configuration in that directory
        # will allow for an easy upgrade of THIS file and
        # make your life easier
        Include "/etc/modsecurity/*.conf"
        Include "/usr/share/modsecurity-crs/*.conf"
        Include "/usr/share/modsecurity-crs/activated_rules/*.conf"

Make sure that mod-security.load is something like that...

LoadFile libxml2.so.2

LoadModule security2_module /usr/lib/apache2/modules/mod_security2.so

Make sure that mod-security is loaded via a2enmod. It should be done by default.

Restart your apache.

You might need to a2enmod headers or apt-get install libapache2-mod-proxy-html
Remove relevant rules if needed.
Also check that the mod-security.conf does not load duplicate conf
Test your injection, it should fail.

The site: https://www.owasp.org/index.php/Category:OWASP_ModSecurity_Core_Rule_Set_Project requires modsecurity >= 2.7.

Connect WPA2 on linux

And so i have a linux that is far from the router.
And i need to connect it via wifi.

apt-get install 

Know your interface first...
nano /etc/network/interfaces

auto wlan0

iface lo inet loopback

iface eth0 inet dhcp

allow-hotplug wlan0

iface wlan0 inet static ( Else use iface wlan0 inet dhcp )

address 192.168.1.155

netmask 255.255.255.0

gateway 192.168.1.1

wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

iface default inet dhcp

nano /etc/wpa_supplicant/wpa_supplicant.conf

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev

VMWare Workstation 12 - Kali Rolling - No internet too...

And so i decided to install Kali on my office laptop.
Which unfortunately, LAN and WIFI is spoilt...
Being a poor guy as usual, did not have money to buy a USB wireless adapter....
So.... 
Lets do it the HARD CORE USB THUMBDRIVE WAY!

Install VMWare.
Get the installer from the website. It's a bundle file.
chmod +x {bundle name}
./{bundle name}
VMWare installation will start.
Next all the way, for CDKEY, google youtube. There's a key out there that works...

After installation, while trying to run vmware
Should get an error saying that some headers are not found.

FUGGGGGG!
No internet, how to update?????

On another internet PC somewhere far far away...
On kali-rolling, the headers are unfortunately linux-headers-4.0.0 ( uname -r )
In the kali-rolling repo, the headers are 4.4.0 ( apt-cache search linux-headers )
HOW HOW HOW!

Let's revert the apt/sources.list and change it to SANA repo.
nano /etc/apt/sources.list
deb http://http.kali.org/kali sana main non-free contrib deb http://security.kali.org/kali-security sana/updates main contrib non-free deb-src http://http.kali.org/kali sana main non-free contrib deb-src http://security.kali.org/kali-security sana/updates main contrib non-free

apt-get flush && apt-get autoremove
apt-get update
apt-cache search linux-headers
You should see that there is a linux-headers-4.0.0

Lets download this and move it to the lousy office laptop.
This command will list the packages (deb) files needed and output to a urls.txt
apt-get -qq --print-uris install build-essential linux-headers-$(uname -r) | cut -d\' -f2 > urls.txt

Lets download the deb files...
mkdir temp
mv urls.txt temp/
cd temp
wget -i urls.txt

Once done, move everything over to the no internet laptop.
dpkg -i *.deb
