recipe_gentoo

Check system configuration for a Gentoo machine (VM or PHYSICAL) based on GRIFON's architecture.
It's a Gentoo OS configuration recipe.
This script normally doesn't modify anything on the system.

To use (with root user) :

mv ./vars.example ./vars.sh  
vim  ./vars.sh # Edit all values which will be used by the script  
./recipe_gentoo.sh [--physical]  

If you cannot execute the script, add the 'x' permission for the user

chmod u+x ./recipe_gentoo.sh

Not finished, in progress....

TO DO :

• Test the recipe check auto-backup (OK, not fully tested)
• Others (script design, documentation...)

Checked points :

• User is root to run the script
• Check requirements
• Installed packages
• Hostname configuration
• DNS configuration (resolve external name, configured nameserver, check if all IPs (scope global) are configured in DNS and check if the hostname has A and AAAA recods in DNS)
• Ping external machine for IPv4 and IPv6
• If Admin IPs are configured
• Services status
• SSH configuration (PasswordAuthentication no, PermitRootLogin no, and ListenAddress only on Admin LAN)
• NRPE basic configuration (allowed_hosts, nrpe_user and nrpe_group)
• MUNIN basic configuration (allow and port)
• SNMP basic config (agentAddress, rocommunity, trap2sink, informsink, sysLocation and sysContact)
• Mail alias configuration (root and operator mail alias configured)
• Check postfix config (inet_protocols, mail_owner)
• Add to check service if they are enabled
• Check portage configuration (FEATURES, PORTAGE_BINHOST, ACCEPT_LICENSE, USE, CHOST, GRUB_PLATFORMS, CPU_FLAGS_X86 and if GENTOO_MIRRORS includes organization mirror)
• Check if IPs (scope global) are recorded in IPAM
• Check if the selected Gentoo profile is the expected profile
• Check if auto-update script is configured (presence, executable and if cron task is configured)
• Check if auto-backup script is configured (presence, executable, content, connection to remote service, if cron task is configured ...)
• Print additional manual verifications (send reporting mail, if /etc conf file need to be updated, if a new kernel can be installed, if server-side for Icinga / SNMP / Munin are configured)
