One of the most used password pentesting method is password dictionary attack. In this case, the cracking tool sequentially checks all possible passwords stored in special files called password dictionary.

Typically, password dictionary store frequently used passwords and familiar words, such as names and place names.

Password Dictionaries may contain words from various languages of the world. Password crackers check them one by one in search of a suitable one.

If you decide to use password dictionary attack, you will need some basic dictionaries or whats called password list.

How To View Block Devices And File System Under RHEL7

Last Updated on May 20, 2021 by Walid Salame Leave a Comment

Under RHEL7 view block devices filesystem is more or less same as we used to do it under RHEL6. Lets understand some interesting commands to view block devices and filesystem under RHEL7.

lsblk:
lsblk command allows you to display a list of available block devices.

lsblk command displays the device name (NAME), major and minor device number (MAJ:MIN), if the device is removable (RM), what is its size (SIZE), if the device is read-only (RO), what type is it (T YPE), and where the device is mounted (MOUNT POINT ). Reember, by default lsblk command shows ouput in tree format. To display the information as an ordinary list, add the -l command line option.
blkid

blkid command, as was under RHEL6, in RHEL7 is used to view information about available block devices.

Be default, the blkid command displays available attributes such as its universally unique identifier (UUID), file system type (T YPE), or volume label (LABEL), as in command one, in above snapshot.

You can also use blkid to display information about a particular device only, specify the device name on the command line – blkid /dev/sda1, as in command two, above snapshot.

Further, you can also use the above command with the -p and -o udev command line options to obtain more detailed information. You need to have root privileges to run the third command in above snapshot.
findmnt

findmnt command allows you to display a list of currently mounted file systems. findmnt command displays the target mount point (TARGET ), source device (SOURCE), file system type (FSTYPE), and relevant mount options (OPT IONS).

Like lsblk command, findmnt lists file systems in a tree-like format. T o display the information as an ordinary list, add the -l command line option.

Exactly like in RHEL6, here in RHEL7 df command allows you to display a detailed report on the system’s disk space usage. df command displays its name (Filesystem ), size (1K-blocks or Size), how much space is used (Used), how much space is still available (Available), the percentage of space usage (Use%), and where is the file system mounted (Mounted on).

Similar like in RHEL6, the df command in RHEL7 shows the partition size in 1 kilobyte blocks and the amount of used and available disk space in kilobytes. To view the information in megabytes and gigabytes, supply the -h command line option, human-readable format.

du command allows you to displays the amount of space that is being used by files in a directory. Like df, du command displays the disk usage in kilobytes. T o view the information in megabytes and gigabytes, supply the -h command line option and to get the summary information only use -s option.

And lastly, you have the gnome-system-monitor tool in rhel7 viewing block devices & filesystem.

Set Your WiFi Card TX Power Higher Than 30 dBm

Last Updated on May 20, 2021 by Walid Salame Leave a Comment

Do you have an Alfa AWUS036NH Wi-Fi adapter that claims it can go to 2000 mWs, or some card that can supposedly transmit power over 1000 mW? If so, you may have run into problems setting your card’s TXPOWER higher than 30 dBm, which is about 1000 mW. Well, I will show you how to break that barrier and go as high as you want!
WARNING Removing all restrictions is illegal in the United States. This tutorial is only for educational reasons, and if you choose to apply it and break the law, then that is your choice and not mine. Please be careful putting this into action.

Changing Your WiFi apadter TX Power

i will showed you how to set your TXPOWER all the way to 30 dBm, or 1 full watt, or 1000 mW.
I’m going to quickly review the commands to do so:

iw reg set BO
iwconfig wlan0 txpower 30

If you try to go over 30, though, you will get an error.
What happens is that the iw reg set command reads the regulatory database for the country that you specified (BO) and comes back with the rules for that country. In Bolivia, the rules are that you can set your txpower to 30 dBm and no more, but if we were to change those rules, we could change how much we can increase it to.
So without further delay, let’s get into how to change that!
NOTE: KALI users have to do it just a tad bit differently. Go to Step 7 to learn what the differences are. The differences occur in Steps 4 through 6.
