DHCP to static ip address doesn't work #18

Open gdeverlant1 opened 7 years ago

gdeverlant1 commented 7 years ago

Moved the issue from other thread to this separate ticket.

I changed also the DHCP Ip address at \etc\network\interfaces.d\eth0 by the following:

auto eth0
#iface eth0 inet dhcp
iface eth0 inet static
address 192.168.1.14
netmask 255.255.255.0   
gateway 192.168.1.1

and rebooted and it seems not to work anymore. Can't access the node via SSH.

@umiddelb In my observation when I do ip a in shell I get this output : 

debian@bambuserver12:~$ ip a

This part is weird I never saw this before in IP on Debian:

inet 192.168.1.34/24 brd 192.168.1.255 scope global eth0

Does it mean that my setting should look like ?:

auto eth0
#iface eth0 inet dhcp
iface eth0 inet static
address 192.168.1.14/24
netmask 255.255.255.0/24
broadcast 192.168.1.255
gateway 192.168.1.1/24

I'Ve found this link with the new replacement of ifconfig by ip :

Finally I've decided to set the IP of the node on my Router statically for the moment it bypass this problem.
