After installing OpenVAS you may need to setup a user. Running the following command will create the user admin and will print the password for the user below.
openvasmd --create-user admin
Example output.
User created with password 'b4539967-c521-fe41-d255-aeb53e735h9a'.
If needed you can delete a user with the following command
openvasmd --delete-user=USERNAME
Boot up the virtual machince
Insert the “Guest Additions CD Image…” from the Devices menu
In the VM, open up Files/Nautilus or Dolphin and find the CD. Open a terminal in the same directory and execute the auto run script
sudo sh autorun.sh
It should pop up another window to install the guest additions. After it is installed, you’ll need to reboot the VM for the new changes to take effect.
You can use find command to find and delete files older than the specified days. In this case 30.
find /backup/* -mtime +30 -exec rm {} \;
Non recursive example. The -prune option should limit find to only look for files in the /backup directory. So it won’t check any subdirectories.
find /backup/* -prune -mtime +30 -exec rm {} \;
Install adb
sudo apt-get -y install adb
Backup with adb
adb backup -apk -obb -shared -all -f ~/Desktop/AndroidBackup.ab
Unlock your phone, authorize usb debugging, and hit “Back up my data”
You may need to enable USB debugging in the developer options in the settings.
Follow output
journalctl -f
Follow service
journalctl -f -u sshd
Print x many lines. Change x to the amount of lines you want printed
journalctl -n 25 -u sshd
Initiate a ssh connection to the server or device you want to use as a proxy. You can change the port to something else if so desired.
ssh username@ipaddress -D 1880
Log in and leave the session running
You can now setup your computer or browser to use the Proxy.
Specify SOCKS Host, hostname is either localhost or 127.0.0.1, the port is 1880.
