nmap_cheatsheet.md

Sat, 31 Jan 2026 00:00:00 +0530

I used zapgpt to create a nmap cheat sheet that you too can follow. Just follow the following steps:

Fist save the output of nmap help command to a file. You can also try with nmap man page but that is too huge :(

`1`	`nmap -h > /tmp/nmap.txt`

Now you have the nmap help output, you can use zapgpt to create the cheatsheet :

zapgpt -p openrouter -m moonshotai/kimi-k2.5 -f /tmp/nmap.txt "Create a 2 page cheatsheet (nicely formatted) for this content. I want you to provide the output in dvi and tell me how to convert that to pdf?"

This will provide you with a text file and how to convert the text to pdf file. I had to use the following commands for converting the tex file to pdf.

Short url to full url

Wed, 19 Jun 2024 00:00:00 +0530

Most of the Social sites will shorten the links. There are a lot of ways to check the url before you go to the url and get phished :)

For example, for bitly you can just add a ‘+’ at the end of the url. For example, you can enter the following in url bar https://bit.ly/2KEOXNx+ and see the details of the where the url takes you. This is just a example url that I got from google but you get the idea.

Run X11 applications on docker or podman

Fri, 29 Mar 2024 00:00:00 +0530

Found x11docker project in github. This is a very nice project if you are trying to run GUI applications in dockers. It takes the hassle out and helps you run the GUI applications very easily in docker.

Whats more, if you are on Fedora, you are in luck. You can install this tool with

`1`	`sudo dnf install x11docker`

and if you are not on Fedora, then head over to their github. Some other distributions also have it packaged but otherwise also it is very simple to install.

Show Local IP

Show local IP

You can see the local IP of the machine with the command - ip a. However if you have to use the address in some variable in a scrit. It becomes little tricky, something like

Show the interfaces in one line with ‘-o’
Show only IPv4 address’s with ‘-4’

and the command looks like

`1`	`ip -4 -o a show dev eth0\|awk '{gsub(/\/.*/,"",$4);print $4}'`

Replace eth0 with then correct interface name.

Openvpn files to nmcli connection

Many times you get openvpn file and when you want to connect to the VPN server, you have to start the vpn client from the cli.

Install a fully functional terminal server capable of accepting connections from RDP(Windows).

Sun, 12 Dec 2010 03:28:43 +0000

Inoformation on xrdp:

The goal of this project is to provide a fully functional Linux terminal server, capable of accepting connections from rdesktop and Microsoft’s own terminal server / remote desktop clients.

  <td>
    <div class="text codecolorer">
      &nbsp;sudo yum install xrdp
    </div>
  </td>
</tr>

There is not much configuration needed for this so I will not go into details. If you are stuck with something though, you can ask in the comments for the post.
