Selecting Ubuntu (22.04 or 24.04) as a primary workstation OS requires a curated set of tools to bridge the gap between functionality and performance. This collection focuses on essential software and configurations for a seamless workflow, primari utilizing apt and snap for package management.

Network and Proxy Management

Proxychains

proxychains is a command-line utility that forces any application's TCP traffic through a proxy (SOCKS4, SOCKS5, or HTTP). Unlike standard environment variables, it works even for applications that do not natively support proxy settings.

Installation: sudo apt install proxychains4

Usage: proxychains4 curl https://google.com

Environment-Based Proxy Control

For shell-level proxying, adding helper functions to your .bashrc or .zshrc simplifies toggling connection settings.

# Enable network proxy
set_proxy() {
    local target_host="${1:-http://127.0.0.1:7890}"
    local bypass="localhost,127.0.0.1,::1"

    export http_proxy="$target_host"
    export https_proxy="$target_host"
    export ftp_proxy="$target_host"
    export all_proxy="$target_host"
    export no_proxy="$bypass"

    printf "Proxy set to: %s\n" "$target_host"
}

# Disable network proxy
unset_proxy() {
    unset http_proxy https_proxy ftp_proxy all_proxy no_proxy
    echo "Proxy environment variables cleared."
}

Privoxy: SOCKS5 to HTTP Translation

Privoxy acts as a web proxy that can forward requests to a SOCKS5 usptream, which is useful for applications that only support HTTP proxies.

sudo apt install privoxy
sudo systemctl enable --now privoxy

Edit /etc/privoxy/config to define the forwarding rule:

# Listen on port 8118
listen-address 127.0.0.1:8118

# Forward all traffic to a local SOCKS5 proxy on port 1080
forward-socks5t / 127.0.0.1:1080 .

Custom DNS Routing

For internal development domains, you can configure systemd-resolved to use specific DNS servers for specific suffixes.

Create a configuration file: /etc/systemd/resolved.conf.d/dev-dns.conf:

[Resolve]
DNS=10.0.0.53
Domains=~internal.corp ~dev.local

Development Stack

Integrated Development Environments (IDEs)

• VS Code: Easiest to maintain via Snap: sudo snap install code --classic.
• JetBrains IntelliJ IDEA: After manual installation, create a desktop entry to enable docking in the Ubuntu launcher.

Example ~/.local/share/applications/intellij.desktop:

[Desktop Entry]
Type=Application
Name=IntelliJ IDEA
Icon=/opt/idea/bin/idea.png
Exec="/opt/idea/bin/idea.sh" %f
Comment=Capable and Ergonomic IDE for JVM
Categories=Development;IDE;
Terminal=false
StartupWMClass=jetbrains-idea

VIM Configuration

A lightweight .vimrc for improved readability and navigation:

" Basic Editor Settings
set nocompatible
set number
set relativenumber
set cursorline
set showmode
set showcmd

" Indentation
set expandtab
set shiftwidth=4
set tabstop=4
set autoindent

" Search Behavior
set hlsearch
set incsearch
set ignorecase
set smartcase

" Encoding
set encoding=utf-8

Input Frameworks

Ubuntu defaults to IBus, but Fcitx5 is often preferred for its performance and modern plugin ecosystem.

To install Fcitx5 for Chinese input support:

sudo apt install fcitx5 fcitx5-chinese-addons fcitx5-config-qt

Configure the environment variables in ~/.profile or /etc/environment:

GTK_IM_MODULE=fcitx
QT_IM_MODULE=fcitx
XMODIFIERS=@im=fcitx

System Management

• RustDesk: An open-source, self-hosted alternative to TeamViewer for remote support.
• HardInfo: A system profiler that provides detailed hardware specifications in a GUI.
• GParted: A critical tool for disk partition management and file system resizing.
