SSH into headless server

Question

Hi,
I'm trying to rescue my headless power pc box at home.
On my desktop machine I'm running ArchLinux and on my headless server the Debian GNU/Linux Wheezy operating system.
The headless server can be booted with an USB stick rescue system.
I have setup my desktop machine to be a DHCPD server. I did followings:
# nano /etc/dhcpd.conf
# Using the google's dns in the example.
# Change it to 192.168.1.1 if you have a dns server installed
option domain-name-servers 8.8.8.8;
option subnet-mask 255.255.255.0;
option routers 192.168.1.1;
subnet 192.168.1.0 netmask 255.255.255.0 {
range 192.168.1.20 192.168.1.020;
I created the following file too:
# nano /etc/conf.d/dhcp
DHCP_ARGS="-q -s 192.168.1.1"
Then I run the following commands:
# netctl stop ethernet-dhcp
# ip link set up dev enp0s20
# ip addr add 192.168.1.1/24 dev enp0s20
# systemctl start dhcpd4.service
and finally I want to connect to my headless server with SSH:
# ssh [email protected]
but get the message:
ssh: connect to host 192.168.1.20 port 22: No route to host
What did I wrong?
Regards, from Paul

The headless power pc box should be my gateway/router that get it's static IP address from my ISP, and my desktop pc box is on LAN of that headless power pc box ( gateway/router ). Actually, I don't know how to setup the /etc/network/interfaces file on headless powerpc box to achieve this goal.
It can't get it's static IP from the ISP, you manually enter that yourself or you have DHCP from the ISP (which is normally the case).  If you use whatever DHCP addresses come from the ISP (hopefully this is private addresses), then you don't really need Arch or anything else serving DHCP.  You might be getting into DHCP competition.  You only need one DHCP server.  If you're doing something complex like PXE booting, then you'll need a router/arch box capable of configuring various DHCP options.  One if by static IP, two if by DHCP, you shouldn't have to deal with your /etc/network/interfaces.  Then you can just figure out what IP has been assigned to your headless box.
