How to connect to a remote server securely using Open SSH (Secure SHell)
Tags: security, linux, devops, aws
Published: 2023-09-09 10:37:54

In this article i will be explaining how we can connect to a remote server using the Open SSH (Secured Shell) protocol.

But before that, we will be getting some basic command checks out of the way.

First, we check the client PC to ensure the SSH directory is currently empty.

```
ls -latr ~/.ssh
```

*Output*

![Output of the above syntax](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/oexiuv3nhg617a3eadfm.png)

### Step 1: 

Generate the SSH key pair (*SSH used the asymmetric cypher for encryption*) 

```
sudo ssh-keygen
```
*Output*

![Output of the sudo ssh-keygen command](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/xkm69dqgsl8bqmwg6tgk.png)

If you noticed the above image, the SSH key pair was created in the /root/.ssh/ directory.

Checking the directory to see the files generated.

```
sudo ls -ltar /root/.ssh
```

*Output*


![Screenshot of the above command](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/31p9n6tlywrv26wpf4o7.png)

**We are done with the client Configuration, SSH on the client has now been installed**

**On to the Server now**

### Step 2:

Install the Open SSH Server software on the Server itself.

```
sudo apt install openssh-server -y
```

### Step 3: 
Now we need to send/transfer the public key on the client computer to the Server using the command (utility tool on the client ssh) on the client:

```
sudo ssh-copy-id -i /root/.ssh/id_rsa.pub username@serverIPAddress
```
----------------------------------------------------------

```
sudo ssh-copy-id -i /root/.ssh/id_rsa.pub afeez@192.168.1.163
```

> You can use the `ifconfig` command to check the IP address of the server

The public key will now be transferred into the server.

To confirm this, run the command on the server.

```
ls -ltar ~/.ssh 
```

*Output*

![Comamnd output](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/39v5qeyf000k5hlkz013.png)

**To confirm the public key is the same you can run a cat command on both files**

### Final Step:
Connect to the remote server using the command:

```
ssh username@remoteserverIP
``` 
-----------------------------------

```
ssh afeez@192.168.1.163
``` 

*Output*

![Ooutput](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/kgfni7uy0nlsbinp3ofe.png)

And BOOM!!!!


![Output](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/hg6dd4vv3qjz2h9g0wyj.png)


We are now connected to the Sever using SSH.

I hope this helps.

GPG secret key: How to change the passphrase
Tags: gpg, gnupg, privacy, encryption
Published: 2023-09-09 09:17:43

## Summary

Suppose you get along with [GPG](https://gnupg.org/) (The GNU Privacy Guard, GnuPG) for good privacy, and sometimes want to change the passphrase of its secret key.

This post shows how to do it.

To be short:

1. Get the secret key ID
2. Run `gpg --edit-key ${the-key}` to start the prompt
3. Run `passwd`

### Environment

- OS: [Devuan](https://www.devuan.org/) [5 - Daedalus](https://www.devuan.org/os/announce/daedalus-release-announce-2023-08-14)
  - A [systemd](https://www.freedesktop.org/wiki/Software/systemd/)-free fork from [Debian](https://www.debian.org/) [Linux](https://www.kernel.org/)+[GNU](https://www.gnu.org/)
- Desktop Environment: [Xfce](https://www.xfce.org/) [4.16](https://www.xfce.org/about/news/?post=1608595200)
- Cryptographic Software: GPG [2.2.40](https://gpgtools.org/releases/gpgsuite/release-notes.html#2022.2)
  - Based on the [OpenPGP](https://www.openpgp.org/) standard as defined by [RFC4880](https://www.ietf.org/rfc/rfc4880.txt)

## Description

First, get the secret key ID by running:

```console
$ gpg --list-secret-keys --keyid-format=long
```

It will print out like below:

```console
/home/${USER}/.gnupg/pubring.kbx
---------------------------------
sec   rsa4096/${KEY:LIKE-123ABC456DEF} 202X-XX-XX [SC]
      ${HASH}
uid                 [...] ${NAME} <${EMAIL}>
ssb   rsa4096/${SUBKEY} 202X-XX-XX [E]
```

Get the key in `sec`.

Next, run `gpg` with `--edit-key` option and the key:

```console
$ gpg --edit-key ${KEY:LIKE-123ABC456DEF}
```

Then it will show information on the key like below and start the prompt:

```console
gpg (GnuPG) 2.2.40; Copyright (C) 2022 g10 Code GmbH
This is free software: you are free to change and redistribute it.
There is NO WARRANTY, to the extent permitted by law.

Secret key is available.

sec  rsa4096/${KEY:LIKE-123ABC456DEF}
     created: 202X-XX-XX  expires: never       usage: SC  
     trust: unknown       validity: unknown
ssb  rsa4096/${SUBKEY}
     created: 202X-XX-XX  expires: never       usage: E   
[...] (1). ${NAME} <${EMAIL}>

gpg>
```

Type as below:

```console
gpg> passwd
```

The current passphrase will be required:

![gpg-change-passphrase-01](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/bilgbql0c4uw7dqv1fvi.png)

Finally, fill the new passphrases:

![gpg-change-passphrase-02](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/xxhk1cnfa528a571bjtb.png)

Done without any output if there is no error.
You can exit with:

```console
gpg> quit
```

## Conclusion

This is how to change the password on GPG.

Wish you privacy protected well 😉

Graph databases as a powerful tool for fraud detection
Tags: apacheage, postgressql, database, opensource
Published: 2023-09-09 08:36:44

**Introduction:**
AgeDB, PostgreSQL, and open-source databases combined offer a potent toolbox for uncovering fraudulent activity in financial transactions.
This article will examine the effectiveness of graph databases in detecting fraud, emphasizing the best methods and practical examples.

**Optimal Data Modeling Techniques**
Following these rules will help you create a strong graph database data model for financial transaction data:


- Finding Important Entities Recognize key players in the network of financial transactions, such as clients, vendors, accounts, and transactions.

- Node and Edge Attributes Specification: Establish node and edge properties to record crucial details such transaction amounts, timestamps, and locations.

- Upholding Consistency To improve the readability and clarity of the data model, use uniform naming rules for the nodes, edges, and properties.

**Best Practices for Querying:**
It is crucial to use the following querying techniques when working with financial transaction data that is organized in a graph database:

- Making Use of Graph Algorithms: Use community detection and PageRank graph techniques to find nodes and edges that might be connected to fraudulent activities.

- Accepting Cypher Use the Cypher query language, which is optimized for graph database querying, to create strong and targeted queries.

- Increasing Query Effectiveness: Caches for frequently used data and a reduction in the amount of nodes and edges fetched each query can improve query performance.

**Real-World Examples**
The efficiency of fraud detection systems powered by graph databases has been shown in numerous situations, including:

- PayPal: Making use of a graph database, PayPal creates models that cover interactions between customers and merchants, account activity, and transaction histories, enabling the proactive detection of fraudulent behavior.

- Mastercard: To create models that describe the connections between cardholders and merchants, transaction trends, and geographic information, Mastercard uses a graph database. This makes it possible to quickly identify fraudulent transactions.

- IBM: IBM uses a graph database to build models that record user behavior, network activity, and security-related events, giving it the capacity to precisely identify fraud and cyber threats.

**Conclusion:**
Finally, the combination of ageDB, PostgreSQL, and open-source databases with graph database capabilities is a formidable weapon in the continuous war against fraud in financial transactions. Organizations can strengthen their defenses against illegal activity and protect their financial ecosystems by following industry best practices for data modeling and querying.
Deploying Apps on Render
Tags: webdev, programming, tutorial, python
Published: 2023-09-09 07:47:06

Deploying is one of the essential stages in development of any softwares or apps. Deploying an app makes it accessible to users, allowing them to use and benefit from the software. Without deployment, the application remains confined to the development and testing environments.Apps are created to provide value to users or organisations. Deployment ensures that the value envisioned during development is delivered to the intended audience.

As we are now aware of the importance of deployment. Let's get into deploying the app. In this scenario, I have chosen a streamlit application which enables us to create custom dashboards or web-apps.

**Pre Requisite:**

1. Have the files of the application on a <a href="https://github.com/Monish3004/test-deployment/tree/ef1058e8d03f069d6972b9305a74a60499feeab7">Github Repository</a> along with the requirements.txt file which contains the necessary packages to be installed.

2. Sign up on <a href="https://render.com/">Render</a>

**Deployment Flow**

1. Access your dashboard which contains the list of apps once you have deployed it.

_Dashboard:_
![Dashboard](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/eolcdcf5sroplzf7cww4.png)
<br>

2.Create a new web service which is accessible from the dashboard.
<br>
![Create a web service](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/1615psdu8adyehxqgzy0.png)
<br>
3.Choose the option of deploying from a GitHub Repository.

![Deploy from GitHub](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/m9jporp2v0jiolj1y8wk.png)
<br>

4.Select the desired repository and connect it.


![Choosing a Repository](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/o7hlxv8kl98xncsb2wha.png)
<br>

5.Name your app with a unique name and do not alter any other details for maximum performance. 
![Name your app](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/w6h0ygoitvow5qpntxwg.png)
<br>

6.Enter the runline or start command to initialise the app. i.e.for streamlit apps :  streamlit run _appname_.py
    for wsgi apps :  gunicorn run _appname_.wsgi

7.The process has been complete and the deployment has been after clicking the button to create web service.The app should be deployed automatically in 5 minutes.

You can access the app that has been deployed with the url allotted to your account.
Checkout the [basic app](https://test-deployment-g0tx.onrender.com) that has been deployed.
