[pkg-dhcp-devel] Bug#791788: dhclient references README file which is not included

[Marc Haber]

Package: isc-dhcp-client
Version: 4.3.2-1
Severity: normal

Hi,

dhclient -v -r eth0 gives the following output:

root at grml ~ # dhclient -v -r eth0
Killed old client process
Internet Systems Consortium DHCP Client 4.3.1
Copyright 2004-2014 Internet Systems Consortium.

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 at 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.

Greetings
Marc
