The machine also had two Ethernet interfaces. eth0 connected to the LAN and eth1 with the cable unplugged. After many tries and debugging I ended configuring the IP manually via the boot parameter ip= which was an option for my use case. I'm raising the severity of this because this breaks automatic IP configuration for any machine with more than one internet interface, which is not uncommon nowadays. signature.asc Description: OpenPGP digital signature

Alexander thanks for your bug report! Your workaround hint was the essential information, that helped us to solve our issues with PXE net boot on our multi-homed servers. Syslinux documents the IPAPPEND flag here: http://www.syslinux.org/wiki/index.php/SYSLINUX#IPAPPEND_flag_val_.5BPXELINUX_only.5D Regards, Jan -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.

Bug#733988: klibc-utils: ipconfig fails to get dhcp on machine with two interfaces
Package: klibc-utils Version: 2.0.2-1 Severity: normal Hi! I'm trying to boot a machine with two e1000e interfaces and nfsroot. It works fine with kernel 3.2.0-4-amd64, but fails to get DHCP address with 3.11.10-1~bpo70+1-amd64. Network is attached only to eth1, eth0 is left unconnected. There is also an IPMI console session over connected interface. Manual network configuration from initramfs shell (root is set to non-existent device to achieve this shell) gives this: (initramfs) ipconfig -t 2 -c dhcp -d IP-Config: eth1 hardware address f4:6d:04:03:28:40 mtu 1500 DHCP IP-Config: eth0 hardware address f4:6d:04:03:27:99 mtu 1500 DHCP IP-Config: no response after 2 secs - giving up (initramfs) ipconfig -t 2 -c dhcp -d eth1 IP-Config: eth1 hardware address f4:6d:04:03:28:40 mtu 1500 DHCP IP-Config: eth1 complete (dhcp from 192.168.0.254): address: 192.168.0.18 broadcast: 192.168.0.255netmask: 255.255.255.0 gateway: 192.168.0.254dns0 : 192.168.0.254dns1 : 0.0.0.0 host : node-18 rootserver: 192.168.0.254 rootpath: filename : In the first case and in the wild ipconfig sends DISCOVER request, but ignores OFFER. To workaround this issue I have to set IPAPPEND 2 in pxelinux config file. -- System Information: Debian Release: jessie/sid APT prefers testing APT policy: (990, 'testing'), (192, 'unstable') Architecture: i386 (x86_64) Kernel: Linux 3.12-1-amd64 (SMP w/4 CPU cores) Locale: LANG=ru_RU.UTF-8, LC_CTYPE=ru_RU.UTF-8 (charmap=UTF-8) (ignored: LC_ALL set to ru_RU.UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages klibc-utils depends on: ii libklibc 2.0.2-1 klibc-utils recommends no packages. klibc-utils suggests no packages. -- no debconf information -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.
