[technique] deux IP pour la même framboise

[toufalk <toufalk@xxxxxxxx>]

Après avoir installé raspbian sur ma framboise, j'ai voulu la passer en
ip fixe. Elle me sert de serveur d'impression.



pi@framboise # cat /etc/network/interfaces
auto lo
iface lo inet loopback

auto eth0
allow-hotplug eth0
iface eth0 inet static
      address 192.168.1.25
      network 192.168.1.0
      netmask 255.255.255.0
      broadcast 192.168.1.255
      gateway 192.168.1.1



Mais depuis mon PC de bureau, j'ai ça :



vincent@bureau $ nmap 192.168.1.*

Starting Nmap 6.40 ( http://nmap.org ) at 2015-12-09 15:56 CET

On voit donc la box, le pc de bureau, la framboise et 192.168.1.11
Et là, je ne comprend plus:



$ ssh pi@192.168.1.11 hostname
pi@192.168.1.11's password:
framboise

$ ssh pi@192.168.1.25 hostname
pi@192.168.1.25's password:
framboise



Le raspberry répond donc aux deux adresses alors qu'il n'a qu'un port
(et un cable). Pourtant,



pi@framboise ~ $ ifconfig
eth0      Link encap:Ethernet  HWaddr b8:e7:eb:64:c4:73

          RX bytes:3683 (3.5 KiB)  TX bytes:3683 (3.5 KiB)



Je ne comprend plus. J'ai désinstallé isc-dhcp-client au cas où ce
serait un coup du client dhcp... mais non.

Des idées pour virer 192.168.1.11 ??
