when i try to ping my raspbian server from my debian computer in the local network i get the "destination host unreachable" error. (the server runs properly, but is reachable neither in the local network, nor beyond.)
i'm looking forward to any responses that help me solve this problem! please bare with me, if i don't understand some technical terms, i'm rather new to linux.
compare the follwoing outputs:
cat /etc/network/interfaces
Code:
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
