I am setting up a DHCP reservation for my Raspberry Pi B+ on the wired connection. It's in another room. After setting up the reservation, I told it to reboot, and it did not get the new reservation. The reservation was for a different address than it currently has.
I tried sudo dhclient
and that did not grab the new address.
I tried sudo dhclient -r
and that killed the connection. Now I have to walk over to it, pull the plug, and hope it grabs a new address.
While a minor inconvenience in this case, how does one force a DHCP renew from the ssh/remote prompt/console?
