Hi,
I connect two MINIXs in the laboratory to finish Bonus Part 2. I tried all the commands mentioned in the pdf, i.e.,
# sudo echo 1 > /proc/sys/net/ipv4/ip_forward
or # sudo sysctl net.ipv4.ip_forward=1
or # su --
For the first two, I got the permission denied and for the last command, I got authentication failure. The password that I input is iew, which is the opening pincode for the MINIX.
Could you please give me some hints on this? Thanks in advance.
