Package: isc-dhcp-client Version: 4.3.2-1 Severity: normal Hi,
dhclient -v -r eth0 gives the following output: root@grml ~ # dhclient -v -r eth0 Killed old client process Internet Systems Consortium DHCP Client 4.3.1 Copyright 2004-2014 Internet Systems Consortium. All rights reserved. For info, please visit https://www.isc.org/software/dhcp/ Listening on LPF/eth0/52:54:00:4d:cc:3d Sending on LPF/eth0/52:54:00:4d:cc:3d Sending on Socket/fallback DHCPRELEASE on eth0 to 192.168.181.13 port 67 send_packet: Network is unreachable send_packet: please consult README file regarding broadcast address. dhclient.c:2331: Failed to send 300 byte long packet over fallback interface. root@grml ~ # Aside from that I find it strange that obviously, the interface is being taken down before dhclient tries to send the DHCPRELEASE, the error message refers the README file which does not seem to be included in the isc-dhcp-common or isc-dhcp-client package. If it refers to the README in the root of the source package, the information is useless for recent Debians since one will only find information about weirdness in Linux kernel versions prior to 2.2 regarding broadcasts. So it would probably the best idea to patch away that referral to the README.
