-# Radionice – Workshop Slide Decks
+# Radionice
 
-This repository contains a collection of slide decks written in Markdown and compiled to PDFs (and optionally handouts) for a variety of workshops.  The slides are organised under the `slides/` directory – each sub‑folder represents a different workshop and contains a single `.md` file along with any required images or resources.
+Usage: `make`
 
-## Quick start
+## Dependecies:
+
+### For Debian:
 
 ```bash
-# List available make targets
-make
-
-# Build all PDFs (default theme: Warsaw Beamer)
-make pdfs
-
-# Remove generated PDFs
-make clean
+sudo apt update
+sudo apt install pandoc
+sudo apt install tikzit
 ```
 
-The `Makefile` uses `pandoc` with the `beamer` template.  If you prefer a different theme, edit the `pandoc` options in the `Makefile`.
+### For Arch:
 
-## Directory layout
-
-```
-slides/
-├─ 3Dprint
-│  ├─ 3DPrint.md
-│  └─ pics/…
-├─ algebragrupe
-│  └─ algebragrupe.md
-├─ ansible
-│  ├─ ansible.md
-│  └─ examples/…
-└─ … (other workshops)
+```bash
+pacman -Sy pandoc texlive-binextra texlive-pictures texlive-latexrecommended texlive-fontsrecommended
 ```
 
-Each workshop folder contains:
-* A single Markdown file (e.g. `ansible.md`).
-* A `pics/` or `examples/` directory with images or code snippets.
-
-## Building requirements
-
-| Tool | Purpose | Debian | Arch |
-|------|---------|--------|------|
-| `pandoc` | Markdown → PDF | `sudo apt install pandoc` | `pacman -S pandoc` |
-| `tikzit` | Optional diagram support | `sudo apt install tikzit` | `pacman -S tikzit` |
-| `texlive-*` | LaTeX backend for beamer | `sudo apt install texlive-binextra texlive-pictures texlive-latexrecommended texlive-fontsrecommended` | `pacman -Sy texlive-core texlive-latexrecommended texlive-fontsrecommended` |
-
-You can also install the full `texlive` bundle if you prefer.
-
-## How to create a new slide deck
-
-1. Create a folder under `slides/` with a descriptive name.
-2. Add a `YourWorkshop.md` file with the Markdown content.
-3. Add any images or auxiliary files into a `pics/` or `examples/` sub‑folder.
-4. Run `make` to see the new target or `make pdfs` to build PDFs.
-
-## Contributing
-
-Pull requests are welcome.  Please keep Markdown styling consistent and ensure all images are correctly linked.  If you add a new workshop, update the `README` section above if necessary.

-# Mail server - 1. deo
-
-# Osnovni koncepti
-
-- SMTP
-- DNS,rDNS
-- IMAP,POP
-- SPF,DKIM,DMARC
-
-# Simple Mail Transfer Protocol
-
-- opensmtpd, postfix (softver za servere)
-- jednostavan protokol (mail from, rcpt to, data)
-- relay (podesava se prosledjivanje ka programu, serveru ili dalje)
-- napravljen za sistemske korisnike
-- auth (autentifikacija za prosledjivanje od nasih korisnika)
-- aliases (redirect na OS korisnika, virtual users moze i vise domena)
-- user db: fajl, sql, ldap
-
-# DNS
-
-- staticka IP adresa zbog spama
-- MX rekord (koji serveri primaju mail)
-- priority (kojim redosledom drugi serveri pokusavaju da dobiju nase)
-- PTR rekord je reverse DNS, ISP ga kontrolise, mi im samo trazimo
-
-# IMAP,POP
-
-- SMTP server konfiguracija: mbox (stari-1 fajl) vs maildir (novi, dir)
-- Local dilivery agent (LDA) (program kome prepustimo da on cuva mejlove)
-- Dovecot je serverski softver za LDA i za protokole IMAP i POP
-- IMAP (cuva na severu, vise klijenata) vs POP (skine mejlove sa servera)
-
-# SPF,DKIM,DMARC
-
-- spam glavni problem
-- DNS se koristi za konfiguraciju + DKIM softver
-- SPF je ACL za outgoing mail (koje IP adrese smeju da salju mejl)
-- DKIM radi sa digitalnim potpisima, odlazne (sign) i dolazne (verify)
-- DMARC za reporting, npr. koliko su dobili nepotpisanih mejlova od "nas"
-- tagovi se koriste za unutrasnje rasporedjivanje mejlova, za match rule
-- grey listing, nije nie whitelist ni blacklist, nego privremeni blacklist
-
-# Sta mi koristimo?
-
-- Nemamo web interfejs
-- Postfix (nazalost)
-- Dovecot (kao LDA i za IMAP)
-- opendkim (servis kome postfix prosledjuje mejlove)
-- LDAP i za postfix SMTP auth i virutal users, a i za dovecot za IMAP
-- Detaljnije u 2. delu predavanja
-
-# Zakljucak
-
-- Lako je primiti mail, ali zbog spama je tesko poslati
-- Gmail ima monopol, uvodi pravila za spam koja nam ne govori
-- Mnogo razlicitih programa, stvara nepotrebnu komplikaciju
-- Stari programi, ali neophodan servis
-- Lako se distribuira na vise servera, ali sinhornizacija fajla potrebna
