Package: udhcpc Version: :1.20.0-7 Severity: normal Tags: d-i udhcpc always returns a domain of "bad" when receiving a valid dhcp ack from an upstream dhcp server. To reproduce first create a shellscript to dump all of the variables set by udhcpc uppon successful receipt of a lease:
echo '#!/bin/sh' > /tmp/export.sh echo 'export' >> /tmp/export.sh chmod +x /tmp/export.sh Then call udhcpc with flags set to call the script: /sbin/udhcpc -s /tmp/export.sh In my environment with a known good/working isc-dhcpd config, the output is: /tmp/udhcpc -s /tmp/sh.sh udhcpc (v1.20.2) started export BOOT_IMAGE='debian-installer/amd64/linux.wheezy' export HOME='/' export LANG='C' export LANGUAGE='en' export MENU='/usr/bin/main-menu' export PATH='/sbin:/usr/sbin:/bin:/usr/bin' export PWD='/' export SHELL='/bin/sh' export SHLVL='1' export TERM='vt102' export TERM_TYPE='serial' export USER='root' export _='/tmp/udhcpc' export initrd='debian-installer/amd64/initrd-wheezy-isc.gz' export interface='eth0' Sending discover...

Testing with isc-dhcp-client also yields a successful lease with the correct domain name set. The major problem with this bug is that when using debian installer the network config generated is always invalid. The domain-name cannot be set in preseed either since the d-i logic in netcfg always give precedence to values received from dhcp. -- System Information: Debian Release: wheezy/sid APT prefers testing APT policy: (500, 'testing') Architecture: amd64 (x86_64) Kernel: Linux 3.2.0-3-amd64 Locale: LANG=C, LC_CTYPE=C (charmap=ANSI_X3.4-1968) Shell: /bin/sh linked to /bin/dash -- To UNSUBSCRIBE, email to debian-boot-requ...@lists.debian.org with a subject of "unsubscribe".
