How to build Zephyr wallet GUI in .rpm package, aka Fedora OS?

25/04/2024 @ Saigon Mining Rig

1. Clone source code

Go to https://github.com/ZephyrProtocol/zephyr-wallet and do git clone

$ git clone https://github.com/ZephyrProtocol/zephyr-wallet

2. Build zephyr wallet client

Change directory to zephyr-wallet/client, install packge dependencies and build

$ cd zephyr-wallet
$ cd client
$ npm install
$ export NODE_OPTIONS=--openssl-legacy-provider
$ npm run build:desktop
$ npm run copy-build

3. Build zephyr wallet desktop app

Change directory to zephyr-wallet/zephyr-desktop-app, install package dependencies.

$ cd zephyr-wallet/zephyr-desktop-app
$ npm install

Modify the file named forge.config.js at line 90. Add a new maker named @electron-forge/maker-rpm. This config is a must for Electron Forge to build .rpm file. For reference, please check https://www.electronforge.io/config/makers/rpm.

{
  name: '@electron-forge/maker-rpm',
  config: {
    options: {
      homepage: 'http://example.com'
    }
  }
}

Now, it’s time to build rpm file, I do reference from zephyr-wallet/sh/make.sh

$ cd zephyr-wallet/zephyr-desktop-app
$ export ZEPHYR_DESKTOP_DEVELOPMENT=false
$ export NODE_INSTALLER=npm
$ npm run make -- --targets="@electron-forge/maker-rpm"

> zephyr@1.0.2 make
> npm run build && electron-forge make --targets=@electron-forge/maker-rpm


> zephyr@1.0.2 build
> tsc

✔ Checking your system
✔ Loading configuration
✔ Resolving make targets
  › Making for the following targets: rpm
✔ Running package command
  ✔ Preparing to package application
  ✔ Running packaging hooks
    ✔ Running generateAssets hook
    ✔ Running prePackage hook
  ✔ Packaging application
    ✔ Packaging for x64 on linux [11s]
  ✔ Running postPackage hook
✔ Running preMake hook
✔ Making distributables
  ✔ Making a rpm distributable for linux/x64 [42s]
✔ Running postMake hook
  › Artifacts available at: /home/***/Projects/zephyr-wallet/zephyr-desktop-app/out/make

The rpm file should be in out/make/rpm/x86/. Done!

For quick testing without rpm install, you can execute zephyr-wallet/zephyr-desktop-app/out/Zephyr-linux-x64/zephyr.

For rpm istall, you can run the following command.

$ cd zephyr-desktop-app/out/make/rpm/x64
$ sudo dnf install zephyr-1.0.2-1.x86_64.rpm

How to fix redash saml's self-sign Certificate Authority?

12/09/2023 @ Saigon Redash

During handling of the above exception, another exception occurred:

Max retries exceeded with url: /FederationMetadata/2007-06/FederationMetadata.xml
(Caused by SSLError(SSLError("bad handshake: Error([('SSL routines', 'tls_process_server_certificate', 'certificate verify failed')])")))

Why does it happen?

Redash trying to get SAML’s FederationMetadata.xml from a self-sign ADFS server. Python package named certifi did not update with your new CA’s certificate.

How to solve?

Find certifi’s cacert.pem and update it. In terminal, type python to access its interactive shell. Then, type the following command.

>>> import certifi
>>> certifi.where()
'/usr/local/lib/python3.7/site-packages/certifi/cacert.pem'

In this case, it’s /usr/local/lib/python3.7/site-packages/certifi/cacert.pem.

Append your CA’s certificate to cacert.pem.

$ cat my-ca.crt >> /usr/local/lib/python3.7/site-packages/certifi/cacert.pem

How to test?

In terminal, type python to access its interactive shell. Then, type the following command.

>>> import requests
>>> requests.request("GET", "https://YOUR_ADFS_DOMAIN/FederationMetadata/2007-06/FederationMetadata.xml")

Good luck!

How to add Certificate Authority (CA) in Fedora to support chain certificate?

09/09/2023 @ Saigon SSL

Step 1. Using chrome to extract certificates.

[1] Open certificate viewer in Google Chrome

Only need to use extract CA’s certificate. Export it with file extension named .pem

Please take a note that, update-ca-trust determines certificate format using file header which locates in very first bytes in the binary file. Eventhough you save certificates with .crt , .cer, it’s still .pem.

To determine file format, you shoule use command file, for example $ file file_name.

To illustrate this point. I’ll give an example.

####### List all file, take a look at the file extension, .crt and .pem
$ ls -l
'Default Trust_DigiCert Global Root CA.crt'
'Default Trust_DigiCert Global Root CA.pem'


####### Determine file format with command named `file`
$ file *
Default Trust_DigiCert Global Root CA.crt: PEM certificate
Default Trust_DigiCert Global Root CA.pem: PEM certificate

Step 2. Copy certificate authority’s certificate to `/etc/pki/ca-trust/source/anchors`

Step 3. Update `/etc/ssl/certs/ca-certificates.crt`

$ sudo update-ca-trust extract

You can check this file /etc/ssl/certs/ca-certificates.crt to ensure that it is updated.

Step 4. Testing

This is an image before update-ca-trust

And, this is an image after update-ca-trust.

Good luck!

How to compile xmrig on Fedora?

02/09/2023 @ Saigon Mining Rig

This is a repost from https://xmrig.com/docs/miner/build/fedora which then I can save my time searching in future.

I. Basic build

Basic build is good for local machine, because it is easy, but if you need to run the miner on other machines please take a look at advanced build.

$ sudo dnf install -y git make cmake gcc gcc-c++ libstdc++-static libuv-static hwloc-devel openssl-devel
$ git clone https://github.com/xmrig/xmrig.git
$ mkdir xmrig/build && cd xmrig/build
$ cmake ..
$ make -j$(nproc)

II. Advanced build

We use build_deps.sh script to build recent versions of libuv, openssl and hwloc as static libraries.

$ sudo dnf install -y git make cmake gcc gcc-c++ libstdc++-static automake libtool autoconf perl
$ git clone https://github.com/xmrig/xmrig.git
$ mkdir xmrig/build
$ cd xmrig/scripts && ./build_deps.sh && cd ../build
$ cmake .. -DXMRIG_DEPS=scripts/deps
$ make -j$(nproc)

Use command ldd xmrig to verify binary dependencies.

How to change DBeaver's heap size?

23/08/2023 @ Saigon etc

Edit /usr/share/dbeaver-ce/dbeaver.ini, change the -Xms and -Xmx. In the example belows, check line 20 and 21.

-Xms: It is used for setting the initial and minimum heap size. I set to 1GB.
-Xmx: It is used for setting the maximum heap size. I set to 6GB.

On Window, it’s C:\Users\user\AppData\Local\DBeaver\dbeaver.ini or C:\Program Files\DBeaver\dbeaver.ini

On Mac, it’s /Applications/DBeaver.app/Contents/Eclipse/dbeaver.ini
