Re: Wait for DHCP client on interface activation

[Alexander Pisarev <apisarev virtuozzo com>]

Hi,

The first connection is fine. But my case is in second connection.
I call this command:

# date && nmcli c up prl_nettool-nm-eth0 && ip a && date                      
Sat Jun 18 04:01:32 EDT 2016
Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/2)

Here you can see start and end time. And in log dhcp response received after the end.
I attach new log. Configuration the same.

Thank you,

Alexander.

Hi,

in the log I see:

  10:04:50 NM[669]: <info>  Auto-activating connection 'prl_nettool-nm-eth0'.
  ...
  10:04:51 dhclient[729]: DHCPDISCOVER on eth0 to 255.255.255.255 port 67
  10:04:51 dhclient[729]: DHCPREQUEST on eth0 to 255.255.255.255 port 67
  10:04:51 dhclient[729]: DHCPOFFER from 10.30.0.25
  10:04:51 dhclient[729]: DHCPACK from 10.30.0.24 (xid=0x79722431)
  ...
  10:04:51 NM[669]: <info>  (eth0): DHCPv4 state changed unknown -> bound
  ...
  10:04:51 NM[669]: <info>  Policy set 'prl_nettool-nm-eth0' (eth0) as default for IPv4 routing and DNS.

At this point eth0 has an address, a gateway and the default
route. After, the connection becomes active:

  10:04:51 NM[669]: <info>  (eth0): Activation: successful, device activated.

When this message is printed nmcli should return successfully; so from
the log it seems that the activation is working as expected and the
interface is configured when nmcli returns. Can you please explain the
problem you are seeing?
