# 👀 Server-Setup Overview

This repository helps you build a complete self-hosted environment on your own VPS or home server. Host your own file server, Git repositories, video conferencing platform, online office suite, RSS reader, file sharing service, uptime monitoring, forms, synchronization tools, email server, vpn server and many other applications—all under your own control.  

*Terminal icerisinde yukari asagi yapmak icin 'Shift+Page_Up' ve 'Shift+Page_Down' tuslarini kullanabilirsin*  
*'sudo dmesg -D' kodu ile terminale yazirilan auid yazilarini o oturum icin kisa sureli durdurur*

In your Server Hosting change (Reverse DNS Management>PTR Records(IPV4 to mail.domain / IPV6 to mail.domain))  

sudo cp /etc/postfix/main.cf /etc/postfix/main.cf.bak  
export TERM=xterm-256color

sudo postconf myhostname  
>myhostname = mail.domain  

openssl s_client -starttls smtp -connect mail.domain:587  
Type>EHLO test 
>250-mail.domain  

PTR Test
dig -x <IPv4> +short  
>mail.domain  

Üçü de mail.domain gösteriyorsa yapı tamamen tutarlı hale gelmiş olur.

# -Wireguard VPN-  
❌ Bence anonimlik değil.  

✅ Ortak Wi-Fi'da tüm trafiğin VPS'ine kadar şifreli gider.  

✅ Nextcloud, Gitea, SSH gibi servislerine güvenli şekilde bağlanırsın.  

✅ İstersen SSH ve yönetim panellerini yalnızca VPN'den erişilebilir yapabilirsin.  

✅ DNS sorgularını da kendi sunucundan geçirerek yerel ağın bunları görmesini engelleyebilirsin.
