This is a follow up post for that one: Hosted Raspberry Pi at PCExtreme – Reinstalled with Raspbian.
I crashed my original OS and asked the kind people at PCExtreme to reinstall my RPi. They did and here is what I did when I received the credentials for the newly set up system:
elk:WhatsMyIP pklaus$ ssh root@bigpi
Warning: Permanently added the RSA host key for IP address '36.29.81.60' to the list of known hosts.

OK, so the time is not correct, but that can be fixed. They connected from firewall-gyro.office.pcextreme.nl last time for login.
[root@alarmpi ~]# cat ~/.bash_history
cd /etc/netctl/
ls
vi eth0
cd examples/ethernet-static ./eth0
cd examples/ethernet-static .eth0
cp examples/ethernet-static /etc/netctl/eth0
cd ../
cd netctl/
vi eth0
nano eth0
reboot
ping google.nl
cd /etc/netctl/

nano /etc/resolv.conf

halt
fdisk -l
passwd root

I don’t think this is the whole bash_history. If you reboot without logging out first, entries get lost…
Let’s check how they configured the static IP address (I changed the IPs though!):
[root@alarmpi ~]# cat /etc/netctl/eth0
Description='A basic static ethernet connection'
Interface=eth0
Connection=ethernet
IP=static
Address=('36.29.81.60/24')
Gateway='36.29.81.3'
DNS=('37.29.81.1')
AutoWired=yes
## For IPv6 autoconfiguration
#IP6=stateless
## For IPv6 static address configuration
#IP6=static
#Address6=('1234:5678:9abc:def::1/64' '1234:3456::123/96')
#Routes6=('abcd::1234')
#Gateway6='1234:0:123::abcd'
Here’s the difference to the template that comes with netctl:
[root@alarmpi ~]# diff /etc/netctl/examples/ethernet-static /etc/netctl/eth0
5,9c5,8
< Address=('192.168.1.23/24' '192.168.1.87/24')
< #Routes=('192.168.0.0/24 via 192.168.1.2')
< Gateway='192.168.1.1'
< DNS=('192.168.1.1')

What about autostart?

What’s the current status of the system?

netctl enable profile
netctl reenable profile
Reenabling IPv6 (see Enable IPv6 with Arch Linux on Raspberry Pi and IPv6 on Arch Linux’ Wiki):
