How do I make a direct connection between two computers via ethernet?
I hooked up an ethernet cable between two computers. I brought up the interfaces, assigned ip addresses and inputed the hostname and MAC address of each by using the arp command. Now, when I try pinging each other, I get an icmp host unreachable message. Both computers' /proc/sys/net/ipv4/icmp_echo_ignore_all is set to 0.
