-# linux_academy
 
-IaC for platfrom to teach Linux and Network Administration.
+# Learning Plattform for Students
+
+## init
+
+Build a reliable platform on a pve host to teach students Linux/Windows server administration and accompanied other interesting topics such as
+
+- firewalls and routing
+- subnetting
+- vlans
+- installing a ms dc/ad
+- join a Linux host to a ms ad
+- powershell usage and scripting
+- smb server setup and joining with ad
+- databases (mariadb/mysql)
+- web servers
+- certificate management
+- mail server
+- security and network tools like nmap or tcpdump
+- and other things
+
+## User Management
+
+Apart from the pve host, the main core of the environment will be a _FreeIPA_ Server which combines
+
+- identity management server (ldap, sso, acl, ...) via a 389 directory server
+- DNS server (bind) 
+- NTP server
+- Kerberos
+- Dogtag for certificate management
+- NFS server or 'advertise' one for home folders of all users and other userful shares when needed in an exercise
+
+
+We will setup user accounts for each student on the ipa server and a home folder for each one which are shared via nfs 
+and automatically mounted on user login on any device in the domain/realm.
+The student will always have their files available no matter the device they login with their own account.
+
+Define designated groups, `linux_admins`, `linux_students`, `linux_users`, with each its own ACLs mediated via the ipa server. 
+
+
+## Facts
+
+**Domain:**
+
+- domain:   `lab.softbox.net`
+- realm:    `LAB.SOFTBOX.NET` 
+- ipa:
+    - hostname:     `ipa.lab.softox.net`
+    - ip address:   `10.11.12.65/24`
+
+
+**Students:**
+
+- username:                 `firstname.surname`
+- mail:                      `firstname.surname@softbox.de`
+- user_ssh_public_key:      Created in exercise sheet-00
+- uid:                      `1000-1020`
+- gid:                       `1000-1020`
+- groups:                    `linux_students` 
+
+**VMs:**

+## Schedule
+
+Time Slot: Friday 3p.m. to 4p.m.
+
+1. Handout Sheets in this week at 4p.m.
+2. Have a 30-60 mins class for the students to ask questions
+3. Discuss sheets next week and handout begin at 1. handing out the new sheet
+
+
+## Ideas for exercises
+
+Separate by different levels of difficulty. In the beginning only easier concepts should be presented. 
+Write guide which can be followed in order to learn and see concepts such as a manual to install a nextcloud instance. 
+In the process the student would learn how a mariadb database is setup. Just following some simple commands.
+
+### Level 0
+
+- [ ] base commands - 20 most useful commands: cd, ls, mkdir, mv, rm , cp, touch, find, grep, cat, ssh
+- [x] ssh key-exchange authentication
+- [x] ssh hardening - not root login, no password hardening
+- [x] nginx
+- [ ] user and group management
+
+### Level 1
+
+- [x] fail2ban-server
+- [ ] samba server 
+- [ ] couple samba share with ms ad
+
+### Level 2
+
+- [ ] git local and remote repo as github and internal gitea
+- [ ] powershell: remote powershell and installation of ninja agent
+
+### Level 3
+
+- [ ] git server
+- [ ] setup mysql/mariadb database
+- [ ] nextcloud setup
+
+### Level 4
+
+- [ ] nmap 
+- [ ] ip and ipcalc - set ip addresses and routes
+- [ ] ufw
+
+### Level 5 
+
+- [ ] simple mail server Ports: 25 (smtp), 587 (submission), 143 (imap) (no tls first)
+- [ ] tcpdump -> catch clear text passwd with tcpdump at imapsync 
+- [ ] pki for mutual tls trust
+- [ ] build each their own firewall/router with openbsd
+- [ ] build together an firewall which will be the sbx_lab firewall

+## TODOs
+
+- [ ] change hostnames and correspondingly the dns entries of the student hosts to `vm_00` -> manage dns via opentofu 
+- [ ] include all users to freeipa and integrate freeipa as main identity and dns server. Deprecate current bind servers -> automate client installation
+- [ ] migrate dns zone to freeipa and manage its bind server with opentofu
+- [ ] create nfs shares for the home folder of each user
+- [ ] write loop for student_vm deployment -> they are similar
+
+- [ ] include automation which install freeipa-client on each vm via opentofu or ansible executed via opentofu
+- [ ] write nice markdown template for sheets. With better code highlighting and better text formatting
