oh dear. Seems like all the time when SSH got the hick-ups on my mac and I blamed the raspberry pi that I was wrong. SSH on my mac sometimes loses connection and tells me the host is down, but when I call top it tells a long uptime. That is weird. Not sure what happens.

I'm installing php and mysql right now, all over a ssh-client on my phone.

Change the names of your raspberryPIs if you have had more than one.

sudo service dhcpcd status

told me to do reload my daemons with

sudo systemctl daemon-reload

No clue and final thoughts for today:

whenever my ssh terminal or the browser tells me that the IP address is not reachable, my cellphone has no problems and likewise the browser, if I connect over dynamicDNS. Whenever I cannot connect over IP, the pizero.local address is also unreachable from my mac. If I then refresh or try to reconnect, it gets back again. Power supply is 1A and it is only the pizero with an OTG connected edimax usb wifi dongle. It must be something with routing in general. I've seen this at my grandmas place too. Gnargh. Is DHCP on jessy a bad thing? I have no idea. Just more questions than before.

This morning I had to wake it up with multiple requests, that made google a bit more. Found kbd settings to play with.

sudo nano /etc/kbd/config

Powersaving and monitor blank set to 0 now

Seems to be a valid thing turning the PI headless (that's what I want for all of them anyway, so, hurray!)

I ran out of mojo again. Maybe it's the WiFi dongle.

sudo nano /etc/modprobe.d/8192cu.conf
