Hey,
I have had a look at the /etc/network/interfaces file in a VPS, and I am surprised by the values of the netmask and the broadcast
255.255.255.255 for the netmask and 0.0.0.0 for the gateway.
I have tried to modify these values for more realistic ones
255.255.255.0 for the netmask and 192.168.10.255 for the broadcast, but then, I can not change the IP values with the vzctl command. And it becomes impossible to do live migration too.
Here is the content of the /etc/network/interfaces file
# Auto generated interfaces
auto lo
iface lo inet loopback
auto venet0
iface venet0 inet static
address 127.0.0.1
netmask 255.255.255.255
broadcast 0.0.0.0
up route add -net 192.0.2.1 netmask 255.255.255.255 dev venet0
up route add default gw 192.0.2.1
auto venet0:0
iface venet0:0 inet static
address 192.168.10.126
netmask 255.255.255.255
broadcast 0.0.0.0
gateway 192.168.10.1
I don't understand why there are two blocs (one for venet0 and the second one for venet0:0)
And why are these values for netmask and broadcast set like this?
To finish with, I have added the IP-address of the gateway in this file, but after checking, it is not needed! It should however be set somewhere, the VPS can not establish an internet connection without the gateway address?
Thank you for your answers and help, and sorry for my bad English!
