Forward Port on Internal IP VPN that is running on the VM using SSH

run this comand inside the vm

ssh -L <vm_ip>:<vm_port>:<vpn_internal_ip>:<vpn_internal_port> <vm_user>@<vm_host>
# Example
ssh -L 10.10.10.11:8080:10.10.186.35:80 user@10.10.10.11

run this comand on your local

ssh -f -L <vm_port>:<vpn_internal_ip>:<vpn_internal_port> <vm_user>@<vm_host> -N
# Example
ssh -f -L 8080:10.10.186.35:80 user@10.10.10.11 -N

And now you can access 10.10.186.35:80 using 10.10.10.11:8080 on your local browser.

Consideration When Using External Resources on Your Web Page

    Unfortunately some network did not have internet connection except you log in to their instance. Before you can even reach the login page, the site you are trying to reach are requesting data to fonts.googleapis.com that mean require any internet connection. This process will stuck and wait until reach the timeout (limit). 

    The other case are when you are try to developing a website with your local environment without charge any internet / data connection. And the last that always hearth-bleeding are waiting for the DNS resolver to solve this issue when they cannot understand what is fonts.googleapis.com domain. 

    Last but not least, you can try to download specific fonts and put it on your web folder or you can just using default fonts that are available without requesting from the external sites. With this concern, I hope your site are very fast to load and not causing any issues because of "unimportant thing" that you copy from the internet.

NPM Install Take So Long and Sometimes Looks Hang

    I am currently using NPM for developing ReactJS and I just test sample code from git. Eventually when I try to install packages for the first time its work normally, because of some reason I try to upgrading some package and reinstall it but the installation process looks hang.

The package that I try to reinstall is react-scripts. Here is some advice from StackOverflow:

• Try to remove package-lock.json (https://stackoverflow.com/questions/50522376/npm-install-hangs-on-loadidealtreeloadalldepsintoidealtree-sill-install-loadid)
• Try to using unix command line (e.g. git bash). (https://stackoverflow.com/questions/64290462/npx-create-react-app-takes-too-long-every-time)
• Try to using `npm install <package> --verbose` to know the progress

Walkthrough:

    I just try install using verbose and hang after checking several packages. I find the pattern which different between the package that pass the check and package that hang, it was the status code (HTTP Response), package that pass check will response with status code 304 (Not Modified) and for the hang one there is no response. I search some solution on StackOverflow and found this 'https://stackoverflow.com/questions/45433130/npm-install-gets-stuck-at-fetchmetadata' that lead me to checking the npm installation registry domain (registry.npmjs.org) which is the global config of my npm registry.

Figure out:

    I try the url of hang package in the browser, for the first time it return ERR_NETWORK_CHANGED that I know because of DNS Server not correctly response my request. After that I try to ping to make sure my connection and it was fine.

Resolve:

    After several test and check, I try to add static route to my hosts list that direct to the npm registry url. I add this line  at the end of file /etc/hosts.

104.16.20.35 registry.npmjs.org

This is the end because when I try install again (with verbose) it was really smooth and the log is show that not only response with status code of 304, it also show the status code of 200.

NMAP

How to Scan Nmap Ports

To scan Nmap ports on a  remote system, enter the following in the terminal:

sudo nmap 192.168.0.1

Replace the IP address with the IP address of the system you’re testing. This is the basic format for Nmap, and it will return information about the ports on that system.

In addition to scanning by IP address, you can also use the following commands to specify a target:

To scan a host:

nmap www.hostname.com

To scan a range of IP addresses (.1 – .10):

nmap 192.168.0.1-10

To run Nmap on a subnet:

nmap 192.168.0.1/13

To scan targets from a text file:

nmap –iL textlist.txt

Note: The developers at nmap.org provide a test server that you can experiment on, located at scanme.nmap.org. You can use this to test your Nmap utility.

Scan a Single Port, All Ports, or Series

Nmap commands can be used to scan a single port or a series of ports:

Scan port 80 on the target system:

nmap –p 80 192.168.0.1

Scan ports 1 through 200 on the target system:

nmap –p 1-200 192.168.0.1

Scan (Fast) the most common ports:

nmap –F 192.168.0.1

To scan all ports (1 – 65535):

nmap –p– 192.168.0.1 

Other Types of Nmap Port Scans

Different types of scans can be performed:

To scan using TCP connect (it takes longer, but is more likely to connect):

nmap –sT 192.168.0.1

To perform the default SYN scan (it tests by performing only half of the TCP handshake):

nmap –sS 192.168.0.1

To instruct Nmap to scan UDP ports instead of TCP ports (the –p switch specifies ports 80, 130, and 255 in this example):

nmap –sU –p 80,130,255 192.168.0.1

Run a fast scan on the target system, but bypass host discovery. (Host discovery uses ping, but many server firewalls do not respond to ping requests. This option forces the test without waiting for a reply that may not be coming):

nmap –Pn –F 192.168.0.1 

The nmap utility can be used to detect the operating system of a particular target:

nmap –A 192.168.0.1

It can also be used to probe for the services that might be using different ports:

nmap –sV 192.168.0.1

Note: The –sV option can be tuned to be more or less aggressive in its scan. Use the ––version-intensity 2 option to specify the level of testing. Replace the number 2 with a number from 0 (light testing) to 9 (run all probes). The more intense the testing, the longer the scan will take.

Common Ports

Here is a brief list of standard ports and their designations:

• 21 – FTP
• 22 – SSH
• 25 – SMTP (sending email)
• 53 – DNS (domain name service)
• 80 – HTTP (web server)
• 110 – POP3 (email inbox)
• 123 – NTP (Network Time Protocol)
• 143 – IMAP (email inbox)
• 443 – HTTPS (secure web server)
• 465 – SMTPS (send secure email)
• 631 – CUPS (print server)
• 993 – IMAPS (secure email inbox)
• 995 – POP3 (secure email inbox)
