But so, crontab doesn't work, "at" also maybe not. TO BE CHECKED * Simple network config in /etc/network/interface. Nothing else needed. * Very simple startup bash script that launch everything. Other scripts in /home/pi/shells/ * Network config via ETH0 o WLAN0, cable o wifi. * Automatic hostname as "raspamiXX" where XX = last number of the wlan0 IP address (same can be done with eth0) * USB wifi dongles already configured with their own firmware etc. * Implement a wifi scanner * Screensaver & screen blanking disabled * Automatic network check: if disconnected, reboot network subsystem, checking every 2 minutes. * VPN access / mosh / screen * VNC access under VPN :) * Chromium installed * ansible and recipes to mod every rasp in the network * USB wifi dongles configured without the FUCKING POWERSAVING MODE. === IDEAS === * underclock sistema? non necessario al momento, non serve a un cazzo- * VPN gestita interamente dai nostri server (zaverio.com) (voyanet cmq e' affidabile ed io sono root su una macchina apposita, quindi non so quanto questo sia necessario) * Mplayer accelerato per rasp pi: fare check su quei 2 link che sono spariti * Test su programma in PYTHON per controllare OMXPlayer, che PARE usi addirittura OSC per fare solo POCHE cose. * Check telecamerina del raspberry e test di streaming audio/video === ACCESSING THE SHIT === USER pi, PW vivabasaglia.

Look also VncHowto !!! === VNC installation on raspberry === Look [[https://www.raspberrypi.org/documentation/remote-access/vnc/]] {{{ sudo apt-get install tightvncserver }}} and launch '''tightvncserver''' to configure it, here you give a password that you will need to access. in '''~/shells/start.sh''' I added {{{ vncserver :1 & }}} === VNC installation on our computers === {{{ sudo apt-get install xtightvncviewer }}} so just launch {{{ vncviewer 172.16.66.9:1 }}} put the pw and desktop appears.

Another solution would be to have your ISP (or whatever institution is responsible for your publicly-routable IP addresses) fix their reverse-DNS record for your IP address on their DNS name servers that are authoritative for the reverse-DNS records for that block of IP addresses. In other words, "make it so people can find your host name based on your IP address, and make sure the hostname they find maps back to your IP address". 7 mins · Unlike · 1 Set into ssh config: '''UseDNS no''' == HIDE X cursor after some seconds of inactivity == {{{ sudo apt-get install unclutter unclutter -display :0 -noevents -grab }}} == Automagic wifi connection == Our wifi: Edimax EW-7811Un 150Mbps 11n Wi-Fi USB Adapter, Nano Size Lets You Plug it and Forget it, Ideal for Raspberry Pi, Supports Windows, Mac OS, Linux IDEAL this DICK!!!

Only /boot for now is read only, /tmp is in tmpfs ramdisk, with some /var links. So crontab is volatile. MAYBE we can put crontab symlinks on /boot so we can have a fixed crontab to be modified into /boot. * [[http://k3a.me/how-to-make-raspberrypi-truly-read-only-reliable-and-trouble-free/]] * [[https://www.raspberrypi.org/forums/viewtopic.php?p=213440]] * [[http://blog.pi3g.com/2014/04/make-raspbian-system-read-only/]] sembra il sistema migliore! provare == HDMI port always ON == WE NEED THIS Because if we don't have hdmi active, the raspberry switches itself on the crappy video out connector.
