dhclient : que signifie « RTNETLINK answers: File exists » ?

I wanted to mettez à jour le DHCP lease of an Amazon EC2 instance, so I executed le suivant command:

user@host:~$ sudo dhclient

Following that, le system's DHCP lease is updated successfully updated. Cependant, le command prints le suivant to le console:

RTNETLINK answers: File exists

What on earth does that mean? Is it a cause for concern?

For what c'est worth, dhclient returned sans tout errors:

user@host:~$ echo $?
0

Basically what happens is that dhclient adds a route to le routing table.

It tries this tandis que le route is déjà in le table.

Check

ip route

for a route qui was added by le dhcp server.

For having le lease renewed do

dhclient -r

if thats pas enough you can remove tous leases by removing le file et getting a nouveau lease

sudo rm /var/lib/dhcp/dhclient.leases; sudo dhclient eth0

Depending on votre exact setup this might be an issue avec having to type votre password twice, so watch out for that.
